Programme Tropical Deep-Sea Benthos (ex MUSORSTOM)
Description
L’un des plus ambitieux programmes hauturiers d'exploration biologique
En 1976, l'Office de la Recherche Scientifique et Technique d'Outre-Mer (ORSTOM) - qui allait devenir l'Institut de Recherche pour le Développement (IRD) - décide d'affecter à son centre de Nouméa son chalutier de recherche, le Vauban. Sur la route depuis Marseille, le navire fait un crochet par les Philippines pour une petite campagne océanographique de 10 jours à la recherche d'un crustacé « fossile vivant ». Le 22 mars 1976, le Vauban retrouve un spécimen de l’espèce Neoglyphea inopinata exactement à l'endroit où l'Albatross avait collecté le premier spécimen, en 1908, au large de l'île de Lubang, par 190m de profondeur. Cette redécouverte spectaculaire s'accompagne d'une moisson d'échantillons dans tous les groupes zoologiques. Jacques Forest et Alain Crosnier, les promoteurs de cette « campagne Musorstom », s'entourent d'un réseau d'experts pour les étudier, les décrire, les publier : c'est l'acte de naissance des « campagnes Musorstom », devenues en 1999 Tropical Deep-Sea Benthos.
Depuis, le programme Tropical Deep-Sea Benthos a réalisé plus de 5 000 opérations de dragage et chalutage dans ce qui constitue l'une des dernières frontières de l'exploration de la biodiversité : le domaine bathyal des grandes îles tropicales. Avec le lancement du navire de recherche Alis, en 1986, le programme connaît un incomparable âge d'or en Nouvelle-Calédonie puis, à partir de 1992, essaime vers les archipels du Pacifique Sud : Vanuatu, Fiji, Wallis & Futuna, Tonga, Marquises, Australes, sous la conduite infatigable de Bertrand Richer de Forges. A partir de 2000, vient le tour des grands archipels de Mélanésie - Iles Salomon, Papouasie Nouvelle-Guinée.
Des partenariats sont noués avec d'autres équipes scientifiques pour l'exploration de Taïwan, des Philippines, de Madagascar et du Mozambique en utilisant des navires locaux. A partir de 2014, le programme s'étend à l'Atlantique tropical américain. Avec 11 millions de km², la France se vante d'avoir la deuxième plus grande Zone Economique Exclusive (ZEE) du monde ; avec Tropical Deep-Sea Benthos, elle a aussi le plus ambitieux programme hauturier d'exploration biologique !
LES NOMBREUSES RETOMBEES DU PROGRAMME
La valorisation des collections engendrées par ces campagnes mobilise plus de 200 scientifiques du monde entier, qui multiplient les superlatifs pour qualifier l'exceptionnelle qualité et diversité du matériel échantillonné. Des centaines d'articles scientifiques, publiés dans les volumes de la série éponyme Tropical Deep-Sea Benthos, une dynamique d'accompagnement de chercheurs invités, des thèses, l'implication d'amateurs de haut niveau : la systématique des organismes marins a bénéficié du remarquable élan collectif d'un programme qui mobilise le savoir-faire de toute une chaîne d'acteurs - équipages des navires, scientifiques embarqués, techniciens de collections, chercheurs, assistants de rédaction.
Au-delà de la découverte de milliers d'espèces nouvelles, le programme a aussi été pionnier dans l'étude des faunes associées aux bois coulés ; il a exploré l'endémisme et la vulnérabilité des monts sous-marins ; il a aussi créé les outils de connaissance qui sous-tendent les politiques de conservation du domaine hauturier tropical. Ces outils prennent une importance notable dans un contexte actuel de « course à la mer et aux ressources » avec notamment un regain d'intérêt pour les ressources minérales sous-marines. Le cas de la Polynésie française est dans ce contexte emblématique : sa ZEE présente les encroûtements polymétalliques les plus riches connus - notamment en cobalt - et les seules données biologiques sur ces environnements sont issues de ces campagnes. De même pour la Nouvelle-Calédonie, les données scientifiques du programme constituent un socle robuste pour la mise en place du plan de gestion du parc naturel de la mer de Corail créé en avril 2014 par le gouvernement de la Nouvelle-Calédonie.

New Caledonia Obducted Peridotite Nappe: Offshore Extent and Implications for Obduction and Postobduction Processes. Tectonics 37(4): 1077-1096. DOI:10.1002/2017TC004722
Résumé [+] [-]One of the largest ophiolitic peridotite masses in the world covers a quarter of the island of Grande Terre, New Caledonia. The Peridotite Nappe was obducted during the Eocene, is weakly deformed, and corresponds to the highest of a structurally simple pile of thrust nappes. We present new marine seismic data that allow us to track the offshore continuation of the Peridotite Nappe along strike for a distance of more than 500 km south of New Caledonia and to image its preobduction, synobduction, and postobduction sedimentary records. Offshore, the Peridotite Nappe underlies a ~150 km wide and 2 km deep basin. Flat-topped horsts of peridotite are clearly bounded by major normal faults; in contrast, faults are obscure onland. To the east, the Peridotite Nappe roots along the eastern margin of the Félicité Ridge (new name), a ~300 × 25 km dome-shaped ridge, which we interpret as being the southern extension of the high-pressure/ low-temperature metamorphic core complex observed in New Caledonia. Two alternative tectonic models address the relative timing and relationships between Peridotite Nappe emplacement, uplift of a metamorphic core complex, and extensional tectonics. These models provide new ideas for the understanding the formation of the eastern margin of the Zealandia continent. Our results contribute to an understanding of how oceanic mantle is emplaced onto continental margins.

Résumé [+] [-]La majorité des informations disponibles sur les minéralisations marines profondes au sein de la ZEE de Nouvelle-Calédonie provient des travaux entrepris par l’ORSTOM (IRD) entre 1970 et 1980. L’objectif de ce projet, mené conjointement entre l’Institut Français pour l'Exploitation de la Mer (IFREMER), le Service Géologique de Nouvelle-Calédonie (SGNC) et l'Agence de Développement Économique de Nouvelle- Calédonie (ADECAL) est de mettre à jour les connaissances sur ces dépôts en utilisant des méthodes analytiques modernes. L'inventaire de tous les échantillons de dragages existants en Nouvelle-Calédonie depuis 1970 a permis de mettre en évidence 104 échantillons présentant des encroûtements au sein et à proximité de la ZEE. Ces échantillons sont principalement localisés au Sud-Est de la Nouvelle-Calédonie, mais également au Nord dans la continuité de la Ride des Loyauté et à l'Ouest sur les monts sous-marins de la Ride de Lord Howe. Une caractérisation chimique et minéralogique de ces minéralisations (XRD/XRF, MEB et ICP-MS) a permis de confirmer qu'elles sont pour la plupart des encroûtements ferromanganésifères hydrogénés, et a également mis en évidence l’originalité de certaines minéralisations associées à une activité hydrothermale et/ou diagénétique, dont la description et l'analyse sont une première en Nouvelle-Calédonie. Les encroûtements ferromanganésifères hydrogénés sont enrichis en métaux de base, traces et terres rares (17,4% Mn, 20,8% Fe, 0,42% Co, 0,31% Ni et 1 307 ppm ΣREE), alors que les minéralisations hydrothermales et/ou diagénétiques sont appauvries en métaux traces et terre rares, mais présentent pour quelques-unes des concentrations fortes en Mn (plus de 50%) et Ni (jusqu'à 0,7%). La comparaison de ces résultats avec ceux issus d'autres océans du globe montre que la Nouvelle-Calédonie se situe dans la moyenne des concentrations en métaux. Les fortes concentrations en Co, Ni et Cu de certains échantillons, ainsi que la physiographie particulière de la zone Sud des rides de Loyauté et de Norfolk, en font une des zones les plus propice pour des investigations supplémentaires. Une première approche, couplant les données de prélèvements, de réflectivité du fond et de bathymétrie haute-résolution, a permis de tester une méthode de prédectivité de présence d'encroûtement sur les sites les plus intéressants et potentiellement minéralisés. La robustesse de ces cartes a été testée en comparant les zones potentielles avec des données vidéo ROV de fonds marins acquises lors de la campagne KANADEEP II. Cette étude a permis de répertorier pour la première fois les minéralisations Fe-Mn de la ZEE de Nouvelle- Calédonie, et d'en caractériser leurs grandes diversités, compositions et morphologies. L'effort d'échantillonnage reste malgré tout insuffisant pour poursuivre l'évaluation du potentiel économique. La poursuite de cette évaluation nécessite la réalisation de campagnes d'exploration dédiées avec des méthodes d'échantillonnage et d'acquisition de données propres à l'étude des minéralisations profondes.

Résumé [+] [-]Located in the South-West Pacific, at the northern extremity of the mostly submerged Zealandia continent, the New Caledonian Exclusive Economic Zone (EEZ) covers 1,470,000 km2 and includes basins, ridges and seamounts where abundant ferromanganese crusts have been observed. Several investigations have been conducted since the 1970s on the nature and composition of ferromanganese crusts from New Caledonia’s seamounts and ridges, but none have covered the entire EEZ. We present data from 104 ferromanganese crusts collected in New Caledonia’s EEZ during twelve oceanographic cruises between 1974 and 2019. Samples were analysed for mineralogy, geochemical compositions, growth rates, and through a statistical approach using correlation coefficients and factor analysis. Crust thicknesses range from 1 mm to 115 mm, with growth rates between 0.45 mm/Ma and 102 mm/Ma. Based on textures, structures, discrimination plots, and growth rates, we distinguish a group of hydrogenetic crusts containing the highest mean contents of Co (0.42 wt%), Ni (0.31 wt%), and high contents of Mo, V, W, Pb, Zn, Nb, from a group of hydrothermal and/or diagenetic deposits showing high mean contents of Mn (38.17 wt%), Ba (0.56 wt%) and low contents of other trace metals. Several samples from this later group have exceptionally high content of Ni (0.7 wt%). The data shows that crusts from the southern part of the EEZ, notably seamounts of the Loyalty Ridge and the Lord Howe Rise, present high mineral potential for prospectivity owing to high contents of valuable metals, and constitute a great target for further investigation.

Neogene to Quaternary evolution of carbonate and mixed carbonate-siliciclastic systems along New Caledonia's eastern margin (SW Pacific). Marine Geology 438: 106524. DOI:10.1016/j.margeo.2021.106524
Résumé [+] [-]Neogene and Quaternary shallow-water carbonate records surrounding New Caledonia main island, Grande Terre, provide a good example for understanding the stratigraphic architecture of tropical mixed carbonatesiliciclastic systems. Due to a southeastern tilt of the eastern margin, the eastern shelf of Grande Terre has been better preserved from erosion than the western part, favouring the development and preservation of shallow-water carbonates. Based on the integration of bathymetric and seismic data, along with paleoenvir onmental and biostratigraphic constraints derived from dredged carbonate rocks, a comprehensive geomor phological and architectural characterization of the offshore eastern margin of Grande Terre has been made. During the Mio-Pliocene, a wide, up to 750 m-thick carbonate build-up developed and extended over at least 350 km from north to south. This Mio-Pliocene build-up, currently lying at 300 to 600 m water depths, is overlain by a Pleistocene-Holocene barrier reef-lagoon complex and associated slope deposits. The switch from aggrading Neogene carbonate banks to backstepping Quaternary platforms likely reflects an increase in accommodation due to a high subsidence rate or to relative sea-level rise, and/or results from a switch in carbonate producers associated with global environmental changes. The internal architecture of the Quaternary barrier reef-lagoon complex is highlighted, especially the development of lowstand siliciclastic prisms alternating with trans gressive shallow-water carbonate sequences. This pattern agrees with the reciprocal sedimentation model typically invoked for mixed sedimentary systems. This stratigraphic pattern is well developed in front of the Cap Bayes inlet in the north of our study area, yet it is not observed southward along the eastern margin. This dif ference suggests that other factors than relative sea-level variations directed the architecture of the margin, such as low terrigenous inputs, lagoon paleo-drainage networks or sediment by-pass towards deep basins.

Molodtsova T. & Budaeva N. 2007. Modifications of corallum morphology in black corals as an effect of associated fauna. Bulletin of Marine Science 81(3): 469–480
Résumé [+] [-]Antipatharians, or black corals, are colonial anthozoans characterized by a chitinous skeletal axis covered to a varying degree with small spines. Important taxonomic features in this group are the size and the structure of polyps, as well as the skeleton morphology, including the mode of branching and/or pinnulation and the spine morphology. Black corals are a characteristic component of seamount suspension-feeding fauna and they often host abundant associated fauna. We examined ~300 antipatharians with symbiotic polychaetes from oceanic rises of the Indo-Pacific region, representing the two families Myriopathidae and Antipathidae. All examined specimens had symbiotic polychaetes of the families Polynoidae [Benhamipolynoe antipathicola (Benham, 1927)] and Eunicidae (Eunice marianae Hartmann-Schröeder, 1998 and Eunice kristiani Hartmann-Schröeder, 1998). It appeared that the morphology of corallum and to some degree the morphology of the skeletal spines was influenced by symbiotic polychaetes. As these features are of a high taxonomic value in antipatharians, they should be used with a caution in black corals with associated polychaete fauna.

Résumé [+] [-]We describe Hesiobranchia lifouensis n. gen., n. sp. from coral reefs at Lifou, Loyalty Islands, New Caledonia in the south-west Pacifi c. It is distinguished from all other hesionids by the presence of two elongated lateral projections on the proboscis, by having both noto- and neurochaetae starting on segment 5, by the presence of parapodial branchiae, and by a unique pigmentation pattern. A morphology-based parsimony analysis of the phylogeny of hesionids indicates that H. lifouensis n. gen., n. sp. belongs within Gyptini and is the sister group of Gyptis Marion & Bobretzky in Marion, 1874.

Résumé [+] [-]The species of Hesione Savigny in Lamarck, 1818 are among the most colorful marine benthic annelids, but their pigmentation often fades in ethanol, rendering it of little use as a diagnostic feature. Further, the body includes only 16 chaetigers but because parapodia are modified after preservation, several authors have lumped most species under a few names. The digestive and reproductive systems are known for a single species (H. sicula delle Chiaje, 1830), and its gonads are hermaphroditic. In order to improve our knowledge of the genus, available specimens in the larger collections of the world were studied under a standardised approach, parapodial/neurochaetal features were defined following previous guidelines, and pigmentation patterns were reassessed. Some observations were made on the digestive system and on some details of the gonads, including Scanning Electron Microscopy (SEM) photos of sperm. Hesione includes 23 species. Twelve were already known: H. ceylonica Grube, 1874 reinstated; H. eugeniae Kinberg, 1866; H. genetta Grube, 1867 restricted; H. intertexta Grube, 1878 restricted; H. pacifica McIntosh, 1885 reinstated; H. panamena Chamberlin, 1919 reinstated; H. pantherina Risso, 1826 restricted; H. picta Müller, 1858 (incl. H. proctochona Schmarda, 1861 and H. vittigera Ehlers, 1887); H. praetexta Ehlers, 1887 reinstated; H. sicula delle Chiaje, 1830 reinstated (incl. H. steenstrupi de Quatrefages, 1866); and H. splendida Savigny in Lamarck, 1818 (incl. H. ehlersi Gravier, 1900); H. reticulata von Marenzeller, 1879 has been recently redefined. Eleven species are newly described: H. beneliahuae n. sp. from La Réunion; H. fitzhughi n. sp. from Australia; H. harrisae n. sp. from Puerto Rico; H. hartmanae n. sp. from the Galápagos Islands; H. helenensis n. sp. from Saint Helena Island; H. horsti n. sp. from Indonesia; H. keablei n. sp. from Australia; H. mooreae n. sp. from Saudi Arabia; H. osbornae n. sp. from the Philippines; H. paulayi n. sp. from Papua New Guinea; and H. uchidai n. sp. from the Philippines.

Salazar-vallejo S.I. 2020. Revision of Leocrates Kinberg, 1866 and Leocratides Ehlers, 1908 (Annelida, Errantia, Hesionidae). Zootaxa 4739(1): 1-114. DOI:10.11646/zootaxa.4739.1.1
Résumé [+] [-]Leocrates Kinberg, 1866 and Leocratides Ehlers, 1908 are two genera of hesionid errant annelids (Hesionidae, Hesioninae) whose species have 16 chaetigers (21 segments). Leocrates species are free living in rocky or mixed bottoms, whereas Leocratides species are usually symbiotic with hexactinellid sponges. Marian Pettibone revised both genera as part of the R/V Siboga Expedition monographs 50 years ago, and most of her ideas have remained unchallenged regarding synonymy for genera and species. For example, she included three genera as junior synonyms of Leocrates: Lamprophaes Grube, 1867, Tyrrhena Claparède, 1868, and Dalhousia McIntosh, 1885, and from 21 nominal species, she regarded only eight as valid. In this revision, all material available was studied, and different morphological patterns were noted in nuchal organs lobes, pharynx armature, and chaetal features. Leocratides species belong to a single pattern; however, in Leocrates several patterns were detected. Three patterns are present for nuchal organs lobes: barely projected posteriorly (horizontal C-shaped), markedly projected posteriorly (U-shaped), and with lateral transverse projections (L-shaped). In the pharynx, upper jaws were noted as single, fang-shaped, or as double, T-shaped structures, whereas the lower jaw can be single, fang-shaped, or a transverse plate. Neurochaetal blades can be bidentate with guards approaching subdistal tooth, unidentate without guards, or with guards hypertrophied projected beyond distal tooth. The combinations of these features are regarded as different genera and consequently, Leocrates is restricted (including Tyrrhena), but Dalhousia, and Lamprophaea (name corrected) are reinstated, and three new genus-group names are proposed: Paradalhousia n. gen., Paralamprophaea n. gen., and Paraleocrates n. gen. Further, the standardization of morphological features allowed several modifications and the recognition of novelties. Thus, four type species were redescribed, four others were reinstated, 10 were newly combined, and 18 from different World localities are described as new. The new species are Lamprophaea cornuta n. sp. from the French Polynesia, L. ockeri n. sp. from the Hawaiian Islands, L. paulayi n. sp. from the Red Sea, L. pettiboneae n. sp. from the Marshall Islands, L. pleijeli n. sp. from La Réunion, L. poupini n. sp. from the French Polynesia, Leocrates ahlfeldae n. sp. from India, L. harrisae n. sp. from the Revillagigedo Islands, L. mooreae n. sp. from New Caledonia, L. reishi n. sp. from the Marshall Islands, L. rizzoae n. sp. from the Seychelles Islands, L. rousei n. sp. from Papua New Guinea, L. seidae n. sp. from the French Polynesia, Leocratides jimii n. sp. from Madagascar, Paralamprophaea bemisae n. sp. from the Maldives, P. crosnieri n. sp. from Madagascar, P. leslieae n. sp. from Kiribati, and P. meyeri n. sp. from the French Polynesia. However, Leocrates japonicus Gustafson, 1930 is a nomen nudum. Keys are included for identifying all hesioninae genera, and for all species in all the included genera.

Patchiness of deep-sea communities in Papua New Guinea and potential susceptibility to anthropogenic disturbances illustrated by seep organisms. Marine Ecology 36: 109-132. DOI:10.1111/maec.12204
Résumé [+] [-]The deep-sea part of the ‘Papua Niugini Biodiversity Expedition’ surveyed the deep-sea environments along the coasts of New Guinea Island in the Bismarck Sea, from the Vitiaz Strait to the border between Papua New Guinea (PNG) and Irian Jaya. This expedition was a follow-up of the BIOPAPUA cruise (2010) that gave some of the first insights into the diversity of the deep-sea fauna of the Bismarck and Solomon Seas for environments other than deep-sea hydrothermal vents. The main aims of the cruise were to survey the diversity of the fauna of (i) hard bottoms that are typically found on deep seamounts, (ii) Astrolabe Bay from 200 m to about 1000 m, (iii) the chemosynthetic environments of the deep sea, including cold-seep environments and plant debris. Astrolabe Bay was one of our targets because its topography allows sampling over the complete bathymetric gradient covered by our sampling gear (down to 1000 m depth), and the recent start of nickel refining activities in the bay is a potential threat to its marine fauna for which little reference data are available. Sampling in the bay revealed not only a diversified fauna associated with soft bottoms and plant debris, but also a chemosynthetic fauna typical of coldseep environments (e.g. siboglinid worms and bathymodioline mussels) below the Ramu refinery. Although the refinery activities had officially started just one week before our work in the area, we observed impacts of these activities. Our molecular work indicates that the siboglinid tubeworm species and one of the two mussel species collected below the Ramu refinery have so far only been documented from this location, despite intensive sampling effort. This illustrates the potential destructive effects of human activities in areas where the diversity and uniqueness of deep-sea communities are poorly understood.

Bitner M.A. 2006. First Record of Brachiopods from the Marquesas Islands, French Polynesia, South Central Pacific. Pacific Science 60(3): 417-424
Résumé [+] [-]Two species of Recent brachiopods, Eucalathis cf. murrayi and Frenulina sanguinolenta, have been identified in the collection from the Musorstom 9 Expedition to the Marquesas Islands in 1997. They represent the first record of brachiopods from the Marquesas Islands. Both species previously have been reported from the western Pacific, and F. sanguinolenta is also known from Hawai'i in the North Central Pacific. Presence of these species in the Marquesas extends the eastern boundary of their biogeographic range. The brachiopods from the Marquesas show very low diversity when compared with the fauna from the western Pacific, as well as with that from the Hawaiian Islands. This decrease in number of species in the Pacific from west to east is also observed in other benthic invertebrate groups.

Résumé [+] [-]Nine species of Recent brachiopods, including two new, belonging to seven genera, i.e. Basiliola beecheri, Abyssothyris wyvillei, Dallithyris pacifica n. sp., Terebratulina japonica, Terebratulina reevei, Terebratulina australis n. sp., Fallax neocaledonensis, Frenulina sanguinolenta, Amphithyris buckmani, and one unidentified rhynchonellide have been recognised in the new material from the Fiji and Wallis and Futuna Islands, collected during the French cruises MUSORSTOM 7, 10 and BORDAU 1. The species Amphithyris buckmani is reported for the first time outside its type locality in New Zealand waters. The brachiopods from Fiji, although less diversified, show affinities to the New Caledonia fauna, having five genera in common.

Gyrothyris williamsi sp. nov. and inter-relationships of some taxa from waters around New Zealand and the southern oceans (Rhynchonelliformea: Terebratelloidea). Earth and Environmental Science Transactions of the Royal Society of Edinburgh 98(3-4). DOI:10.1017/S1755691008075142
Résumé [+] [-]This paper describes a terebratelloid articulate brachiopod, Gyrothyris williamsi sp. nov., based on 95 specimens from seamounts on the Lord Howe Rise, Coral Sea, SW Pacific Ocean. The new species is attributed to Gyrothyris on the basis of (a) morphological and growth trajectory similarities; (b) phylogenetic analyses of an alignment of DNA sequence (similar to 2900-sites) obtained from nuclear-encoded small- and large-subunit ribosomal RNA genes (SSU and LSO; and (c) the presence of a distinctive, two-part deletion in the LSU gene. It is distinguished morphologically from Gyrothyris mawsoni and its subspecies by both internal and external morphology and by its isolated geographical distribution, which extends the patchy, known range of this genus to an area some 2000 km north of its previous northern limit around New Zealand. Phylogenetic analyses of the rDNAs and of mitochondrial cox1 gene sequences (663 sites) confirm previous indications that the New Zealand endemic terebratelloid genera form a clade (Neothyris (Calloria, Gyrothyris, Terebratella), but the position of Terebratella with respect to Calloria and Gyrothyris remains weakly established. These sequences disagree inexplicably about the closeness of the relationship between Neothyris parva and N. lenticidaris. Analyses of the first sequences from Calloria variegata, a species restricted to the Hauraki Gulf, New Zealand, are consistent with the possibility that it originated locally, and recently, from C inconspicua. Magellania venosa from S. America/Falklands joins with Antarctic Magellaninia fragilis and M. joubini to form an rDNA clade that excludes Terebratalia as the putative sister-group of the New Zealand terebratelloid clade. The cox1(but not the rDNA) sequences of the New Zealand clade pass a test for clock-like rates of evolution, and maximum likelihood pairwise distances suggest that if genetic isolation between the ancestor of Antarctic Magellania and the last common ancestor of the New Zealand terebratelloid clade was initiated by separation of the Antarctic and New Zealand plates similar to 90 Mya, isolation from M. venosa was initiated earlier, perhaps similar to 145 Mya. However, in the simple phylogenctic reconstruction presented here from cox1 sequences, S. American and Antarctic Magellania spp. do not yield a well-supported clade, perhaps because of differences in base composition.

Bitner M.A. 2007. Recent brachiopods from the Austral Islands, French Polynesia, South-Central Pacific. Zoosystema 29(3): 491
Résumé [+] [-]Four Recent brachiopod species, including one new, Acrobrochus marotiriensis n. sp., Dallithyris pacifica Bitner, 2006, Megerlia truncata (Linnaeus, 1767) and Thecidellina maxilla (Hedley, 1899), have been recognised in the material collected during the French BENTHAUS Expedition to the Austral Islands (French Polynesia) in 2002. The Austral Islands are situated on the south-eastern limit of the Indo-West Pacific biogeographic Province. This is the first record of brachiopods from off the Australs. Dallithyris pacifica, M. truncata and T maxilla have been already reported from the southern Pacific, while the genus Acrobrochus is noted for the first time from the Pacific. Acrobrochus marotiriensis n. sp. belongs to the short-looped brachiopods. Its loop is characterized by a very broad, gently folded transverse band. The triangular outer hinge plates are margined by a small elevation of the, crural bases. This species differs from congeneric species in its smaller size, its less elongate outline and its greater convexity

Résumé [+] [-]Twenty-two brachiopod species belonging to 19 genera have been recognized in the material collected during two cruises, Norfolk 1 and Norfolk 2, to the Norfolk Ridge south of New Caledonia, at depths of 180 to 1150 m. Thirteen species are reported for the first time from this locality, while four genera, Aulites, Septicollarina, Annuloplatidia and Campages, are noted for the first time from the New Caledonian region. Thecidellina minuta is recorded for the first time from the Pacific. Four new species are described - Cryptopora norfolkensis sp. nov., Aulites crosnieri sp. nov., Septicollarina zezinae sp. nov. and Annuloplatidia richeri sp. nov. The distribution of the particular species and their abundance vary considerably between the 15 sampled seamounts, with Stenosarina crosnieri and Fallax neocaledonensis being most widely distributed, and the seamount Crypthelia having the highest biodiversity. The seamount brachiopods show considerable affinity to the brachiopods of adjacent regions, and only three species - C. norfolkensis, A. crosnieri and A. richeri - can be regarded as potential endemics. The brachiopod fauna is more similar to that in the area around Fiji than to that around Australasia.

Résumé [+] [-]Twelve species of recent brachiopods belonging to the genera Lingula, Discradisca, Novocrania, Xenobrochus, Eucalathis, Frenulina, Argyrotheca, Campages, Thecidellina and Lacazella were identified in samples collected during shallow-water cruises around New Caledonia, southwest Pacific. Six genera, Lingula, Xenobrochus, Eucalathis, Frenulina, Campages and Thecidellina, have been already reported from the New Caledonian region, while four genera, Discradisca, Novocrania, Argyrotheca and Lacazella are the first records from this region. Additionally, Discradisca stella is the first discinid brachiopod recognized in the New Caledonia area. One new species is described, the megathyridid Argyrotheca neocaledonensis n. sp. The biogeographical affinities of the New Caledonia brachiopod faunas are briefly discussed.

Résumé [+] [-]The genus Xenobrochus, with the type species Gryphus africanus COOPER, 1973, was erected for short-looped brachiopods of small size, rectimarginate and having a loop with anteriorly convex transverse band. A new species of Xenobrochus, X. norfolkensis sp. nov. has been identified in the material collected during the French cruises SMIB 8, NORFOLK 1 and NORFOLK 2 to the Norfolk Ridge, New Caledonia, SW Pacific. This species differs from those hitherto described in the absence of cardinal process and relatively wide outer hinge plates. The genus, represented now by nine species, has a distribution restricted to the Indian Ocean and West Pacific.

Résumé [+] [-]Six species of recent brachiopods have been identified in material collected during the French Tarasoc Expedition to the Tarava Seamounts and the Society and Tuamotu Islands, French Polynesia, in 2009. Two of them, Frenulina sanguinolenta (Gmelin, 1790) and Thecidellina maxilla (Hedley, 1899), have already been reported from the studied region. Two species, Discradisca sparselineata (Dall, 1920) and Septicollarina zezinae Bitner, 2009, are reported for the first time from French Polynesia, and two other species are described as new, Dallithyris tahitiensis Bitner, n. sp., and Annuloplatidia curiosa Bitner, n. sp., although the latter species was already recorded from French Polynesia, ascribed to a different taxon. When compared with the brachiopod fauna from the southwestern Pacific, that of French Polynesia is taxonomically depauperate, which might reflect the younger geological age of the islands of the central Pacific.

Comparison of articulate brachiopod nuclear and mitochondrial gene trees leads to a clade-based redefinition of protostomes (Protostomozoaand ) and deuterostomes (Deuterostomozoa). Proceedings of the Royal Society B: Biological Sciences 265: 475-482
Résumé [+] [-]Nuclear and mtDNA sequences from selected short-looped terebratuloid (terebratulacean) articulate brachiopods yield congruent and genetically independent phylogenetic reconstructions by parsimony, neighbour-joining and maximum likelihood methods, suggesting that both sources of data are reliable guides to brachiopod species phylogeny. The present-day genealogical relationships and geographical distributions of the tested terebratuloid brachiopods are consistent with a tethyan dispersal and subsequent radiation. Concordance of nuclear and mitochondrial gene phylogenies reinforces previous indications that articulate brachiopods, inarticulate brachiopods, phoronids and ectoprocts cluster with other organisms generally regarded as protostomes. Since ontogeny and morphology in brachiopods, ectoprocts and phoronids depart in important respects from those features supposedly diagnostic of protostomes, this demonstrates that the operational definition of protostomy by the usual ontological characters must be misleading or unreliable. New, molecular, operational definitions are proposed to replace the traditional criteria for the recognition of protostomes and deuterostomes, and the clade-based terms 'Protostomozoa' and 'Deuterostomozoa' are proposed to replace the existing terms 'Protostomia' and 'Deuterostomia'.

Résumé [+] [-]Brachiopod and phoronid phylogeny is inferred from SSU rDNA sequences of 28 articulate and nine in- articulate brachiopods, three phoronids, two ectoprocts and various outgroups, using gene trees reconstructed by weighted parsimony, distance and maximum likelihood methods. Of these sequences, 33 from brachiopods, two from phoronids and one each from an ectoproct and a priapulan are newly determined. The brachiopod sequences belong to 31 di¡erent genera and thus survey about 10% of extant genus-level diversity. Sequences determined in di¡erent laboratories and those from closely related taxa agree well, but evidence is presented suggesting that one published phoronid sequence (GenBank acces- sion U12648) is a brachiopod phoronid chimaera, and this sequence is excluded from the analyses. The chiton, Acanthopleura, is identi¢ed as the phenetically proximal outgroup; other selected outgroups were chosen to allow comparison with recent, non-molecular analyses of brachiopod phylogeny. The di¡erent outgroups and methods of phylogenetic reconstruction lead to similar results, with di¡erences mainly in the resolution of weakly supported ancient and recent nodes, including the divergence of inarticulate brachiopod sub-phyla, the position of the rhynchonellids in relation to long- and short-looped articulate brachiopod clades and the relationships of some articulate brachiopod genera and species. Attention is drawn to the problem presented by nodes that are strongly supported by non-molecular evidence but receive only low bootstrap resampling support.

Résumé [+] [-]We present maximum likelihood and Bayesian inference relative time-tree analyses of aligned gene sequences from a worldwide collection of craniiform brachiopods belonging to two genera, Novocrania and Neoancistrocrania. Sequences were obtained from one mitochondrial and three nuclear-encoded ribosomal RNA genes from varying numbers of specimens. Data-exploration by network (splits) analyses indicates that each gene identifies the same divergent clades and (with one minor exception) the same inter-clade relationships. Neoancistrocrania specimens were found only in the Pacific Ocean, near Japan, on the Norfolk and Chesterfield Ridges, and near the Solomon Islands. The Novocrania clades, in approximate order of increasing distance from the root comprise 1. a ‘Northern’ clade of animals collected in the NE. Atlantic, W. Mediterranean and Adriatic; 2. a ‘Tethyan’ clade comprising animals from the E. Mediterranean, Cape Verde islands and the Caribbean (Belize and Jamaica); 3. a ‘NE. Pacific’ clade containing animals from Vancouver Island and from localities near Japan and south of Taiwan; 4. a ‘Southern’ clade that contains two widely separated subclades, one from New Zealand and the other with an extraordinarily wide distribution, ranging from near Japan in the north to the Chesterfield Ridge and Solomon Islands in the West, and in the East to the Galapagos Islands, the coast of South America (Chile) and Richardson seamount (off South Africa) in the South Atlantic. To the South, members of this clade were found in the Weddell, Scotia and Bellinghausen Antarctic Seas. The root of the extant craniid radiation was previously found (by relaxed-clock analysis) to lie on the branch connecting the two genera so that, in effect, the one clade of Neoancistrocrania serves to polarise evolutionary relationships within the several clades of Novocrania. As previously suggested, all results confirm that Neoancistrocrania is sister to the ‘Northern’ Novocrania clade, and this leads to a proposal that Neoancistrocrania represents one extreme of a wide range of variation in ancestral ventral valve mineralisation, speciation (∼90 Ma) resulting from competitive exclusion in rapidly-growing reef environments. To the extent possible, the identified molecular clades are correlated with named species of Novocrania. The reproductive and population biology of craniid brachiopods is not well known, but from available evidence they are considered to have low-dispersal potential and, except in enclosed localities such as cold-water fjords, to have small effective population sizes, features which are consistent with the observed divergent populations in well-separated localities. Exceptionally slow craniid molecular (rDNA) evolution is suggested by the short branch of Novocrania where it has been used as an outgroup for large-scale analyses of metazoans. Slow molecular evolution is also indicated by the existence of a distinct Tethyan clade, reflecting restricted dispersal at former times, and by the uniform, short, genetic distances and exceptionally wide geographical distribution of the Southern clade. Thus, the geographical distribution and phylogenetic divergence of craniid brachiopods is an example of phylotectonics, in which relationships revealed by phylogenetic analyses reflect opportunities for dispersal and settlement that were created by tectonic plate movements associated, in this case, with opening and closure of Tethys and the breakup of Gondwana. Molecular dating of craniid divergences and radiochemical dating of tectonic events thus illuminate one another.

Mémoires du Muséum national d'Histoire naturelle 168:55-123, ISBN:2-85653-501-1
Résumé [+] [-]A systematic study of the ctenostome and anascan cheilostome (malacostegan, cellularine, and scruparioid) Bryozoa collected during the recent set of MUSORSTOM cruises has yielded 12 families, 26 genera and subgenera, 51 species and 4 subspecies, mostly from bathyal depths. Only 6 of the species have previously been recorded from New Caledonian waters. The new taxa comprise 1 family (Leiosalpingidae), 3 genera (Candomenipea, Candoscrupocellaria, Astoleiosalpinx), 2 subgenera (Beanodendria, Thaminozoum), 15 species and 4 subspecies. Also newly recorded for the first time from New Caledonian waters are 5 families (4 ctenostomatous), 14 généra (4 ctenostomatous) and 25 species ; 11 of the latter are common to New Caledonia and New Zealand in deeper waters.

Résumé [+] [-]This study concerns the systematics of Entoprocta and Cheilostomate Bryozoa (infraorders Pseudomalacostegomorpha and Cryptocystomorpha) collected during various cruises around New Caledonia. One new entoproct species is described in the genus Loxokalypus, and 12 families (1 new), 27 genera (2 new), and 40 species (16 new) of Bryozoa are recorded. The new bryozoan taxa comprise the family Bryopastoridae, the genera Lamoitrouxia and Promicroa and the subgenus Henrimilnella. A new key is provided for the identification of genera of Cellariidae. A new species of the buguloidean bryozoan Himantozoum is also provided. The genus Pseudothyracella, previously known only from the Paleogene of Northwestern Europe and North America, is represented by a new, living species. Thirteen genera and 19 species are newly recorded in the New Caledonian fauna.

D'hondt J.L. 2006. Description of two new genera and three new species of ctenostomatous Bryozoa. Bulletin de la Societe Zoologique de France 131(4): 247-260
Résumé [+] [-]Description and discussion of Cephaloalcyonidium, gen. nov., a new genus of claviform ctenostomatous bryozoans, morphologically and structurally intermediate between the pedunculate species of Alcyonidium (the most evolved species within the family Alcyonidiidae) and the Clavoporidae sensu stricto, in which this genus is placed. The new taxon is currently monospecific for the species Cephaloalcyonidium morchellanum n. gen., n. sp. The family Clavoporidae is divided into two subfamilies. A new type of coenozoecia, the «polypido-myoecia» is characterized. Descriptions are given of Alcyonidium torpedo, n. sp., with lobed zoarium, and of the new genus (incertae sedis) Pseudobathyalozoon (with P. profundum as type-species), related to the genera Bathyalozoon, Farrella, Mimosella and Triticella.

Résumé [+] [-]Knowledge of the little-known cheilostome bryozoan family Petalostegidae has hitherto been based on only two extant species (Petalostegus bicornis (Busk) and P. spinosus Powell), and an Australian Miocene species (P. tenuis (Maplestone)). Previously, these have been included among the anascan superfamily Buguloidea. With the discovery of a remarkably diverse petalostegid fauna in New Caledonian waters (especially on the northern Norfolk Ridge), it is apparent that the family is neither " anascan " nor monogeneric. The obscure monotypic Australian Miocene genus Chelidozoum Stach is now recognised as petalostegid, based on the discovery of four, new. Recent species (including one from off Victoria). Among these species there is a reduction in the size of the costal field from five spines, through three, to two. The known species of Petalostegus Levinsen are redescribed and four new species are described (including one from the New Zealand deep sea). The family, which is entirely southern-hemisphere in distribution, is now included in the ascophorine superfamily Catenicelloidea. Evidence of predation on embryos is seen from boreholes in ovicells of two species of Petalostegus.

Résumé [+] [-]The present paper deals with bryozoans in three of the four infraorders of the large suborder Ascophorina (order Cheilostomatida) from MUSORSTOM cruises along the northern Norfolk Ridge and around New Caledonia (including five species from the MUSORSTOM 3 cruise to the Philippines included with the other material). A total of 44 species is recorded (Cribriomorpha : 35 species; Hippothoomorpha : 1 species; Umbonulomorpha : 8 species) of which 22 species are new. A noteworthy feature in New Caledonian waters is the remarkable diversity of two families — the Petalostegidae and Bifaxariidae. Proportionally more species of these families are found here than anywhere else in the world.

Résumé [+] [-]The discovery of living species of the predominantly Tertiary catenicellid subfamily Ditaxiporinae on the Norfolk Ridge has necessitated a revision of the subfamily, which is characterised by biseriate multizooidal segments. The type species of the genera of Ditaxiporinae and of the related family Ditaxiporinidae were examined by scanning electron microscopy, leading to the recognition of six genera (two new) and 18 species (four new) and the incorporation of the Ditaxiporinidae into the Ditaxiporinae. The earliest occurring species is Caberoides rockallensis sp. nov. In the late Paleocene of the North Atlantic. There are only two living species - Bryosartor sutilis gen. et sp. Nov. and Plagiopora recens Gordon, both on the northern Norfolk Ridge. A new monotypic genus, Ahcheethamia, is introduced for Caberoides corniculatus Cheetham from the British Eocene. With the exception of two species from North America, the subfamily is clustered in two centres of diversity - northwestern Europe and Australasia, the latter including Caberoides miranda sp. nov. and Plagiopora alma sp. nov., both newly recorded from the Eocene of New Zealand. Thus a Tethyan distribution of the subfamily was achieved relatively early in the Paleogene. Just as in other catenicellids, there seem to have been parallel trends in the Ditaxiporinae in the diversification of the frontal shield from a spinocyst to a perforated gymnocyst on the one hand and with cryptocystal elements (derived from expanded shallow pore-chambers) on the other. A unique development is indicated by the genus Vasignyella. Hitherto included in the family Savignyellidae, Vasignyella appears to have been derived from Ditaxiporina or a common ancestor by reduction to unizooidal segments and the loss of ovicells. A new subfamily of Catenicellidae, Vasignyellinae, is established for tliis genus.

Résumé [+] [-]This paper describes a fauna of 98 species of ascophorine bryozoans from 1984-89 MUSORSTOM cruises, mainly in the New Caledonian EEZ. Ten of the species occur solely in the Philippines and some species occur in both regions. The fauna is noteworthy for its endemism (57 of the 84 New Caledonian species, i.e., 68%, are endemic) and its high taxonomic novelty, the latter contributing to a clearer appreciation of the taxonomic limits of some genera and families. Two new families (Phorioppniidae, Buffonellodidae), 54 new species, and 16 new genera are described, mostly from New Caledonia; some, from elsewhere, are the consequence of systematic revision. The new genera are: Xynexecha (Exechonellidae), Parkermavella (Bitectiporidae), Phorioppnia, Oppiphorina, Punctiscutella (Phorioppniidae), Haswelliporina, Mosaicoporina (Porinidae), Wrigiana, Ijimaia (Calwelliidae), Ipsibuffonella, Maiabuffonella (Buffonellodidae), Macrocamera (Eminoeciidae), Pseudoplatyglena (Euthyrisellidae), Richbunea (Celleporidae), Lifuella (Phidoloporidae), and Ptoboroa (Batoporidae). The most speciose family in the collection is the Phidoloporidae, represented by 7 genera and 19 species. The most speciose genus in the collection is, remarkably, the little-known deep sea genus Siphonicytara, with 6 species, all new, which more than doubles the number of species previously described. Ten of the species in the New Caledonian fauna studied here are shared only with New Zealand, and 4 only with the Philippines .

Résumé [+] [-]Twenty six species of brachiopods were dredged in the bathyal area surrounding New-Caledonia and the Chesterfield Islands, from 1985 to 1989, during the cmises BIOCAL, BIOGEOCAL, CALSUB, CHALCAL 2, MUSORSTOM 4, 5, 6, SMIB 1, 4, and VOLSMAR. That fauna shows a broad diversity, including 19 genera belonging to 14 families. A new genus {Kanakythyris) and four new species are described {K. pachyrhynchos, Stenosarina globosa, S. lata, Fallax neocaledonensis). Several species are strongly sulcate {Neorhynchia strebeli. Abyssothyris wyvillei, K. pachyrhynchos, Nipponithyris afra), a feature that is usually considered as typical of deep-sea brachiopods. Nevertheless, this feature also occurs in New-Caledonian species at lesser depths. Moreover, in several taxa, size differences between populations or species seem to be related to depth.

Résumé [+] [-]Although a number of brachiopod genera have been defined mainly from their internal structures, the fixity of those structures has rarely been investigated. Variability of the rather simple loops of two New Caledonian species of the Recent genus Stenosarina (Terebratulida), one species having a variant with endemic morphology, provides insight into the relationship between the two species. Procrustes methods based on landmarks are used. Intra-population variability is found to be of the same order of magnitude as inter-population variability. Moreover, the morphological distance between the endemic variant and the other specimens is greater than the distance between the two species of Stenosarina. The study also identifies a morphocline between the three forms of Stenosarina under study.

Tort A. 2003. Morphological plasticity of the outline and the internal structures of the shell of the recent Terebratella tenuis sp. nov.(Brachiopoda, Terebratulida). Zoomorphology 122(1): 47–54
Résumé [+] [-]The practice of classifying articulate brachiopods, including Terebratulida, from minor morphological features and internal structures has led to a proliferation of genera and species, especially when external morphology is quantified by conventional measurements. Morphological plasticity and variability of the internal structures have been studied in a large sample from a population of a species (described in this paper), Terebratella tenuis sp. Nov. The shell outline is evaluated by using Fourier series while internal structures are measured by conventional methods. Both the external morphology and the internal structures of T. tenuis sp. Nov. Are highly variable and this study shows that allowance must be made for such variability when describing species. A number of internal structure indices commonly used in brachiopod species description are found to be subject to intense variation or even growth allometries. There are also asymmetric resorptions of the internal structures. These results demonstrate that morphological variability is not taken into account as much as it should be in the definitions of Recent or fossil species.

Zezina O.N. 2005. On the systematic position of some recent brachiopod species from the Norfolk Ridge (West Pacific). Invertebrate Zoology 2(1): 29-33
Résumé [+] [-]Five species of brachiopods were found in 7 samples obtained during the cruise Norfolk 2. These species were known before from this region. Four of these species are common and are considered as markers of the deep-sea biofilter, distributed globally in the upper bathyal of continental slopes and seamounts. This deep-sea biofilter remains poorly explored at low latitudes of the Western Pacific. The systematic position of examined species has been clarified. Neoancistrocrania norfolki Laurin, 1992 is included in the family Valdiviathyrididdae Helmcke, 1940. Stenosarina crosnieri (Cooper, 1983) is relocated to the genus Dallithyris Muir-Wood, 1959. A new genus, Laurinia gen. n., was established after the study of soft tissues of Fallax neocaledonensis Laurin, 1997.

Résumé [+] [-]Species of the bothid genus Arnoglossus collected from waters around New Caledonia are reviewed. Seven species, including two new species, two new zoogeographical records and three species already recorded from the region were identified, being Arnoglossus septemventralis sp. nov. and A. nigrifrons sp. nov., A. tenuis, A. elongatus, and A. macrolophus, A. japonicus and A. polyspilus, respectively. Arnoglossus septemventralis sp. nov., described from ten specimens collected between 230-315 m off southern New Caledonia, is easily separable from all other members of the genus in having seven pelvic rays on both sides. Arnoglossus nigrifrons sp. nov., described from two specimens collected from 300-315 m on the Chesterfield Plateau and northwest of New Caledonia, is characterized by a rounded upper head profile, several anterior dorsal fm rays elongated in males, gill rakers without serrations and a darkened head region. Arnoglossus tenuis, collected from 10-16 m off New Caledonia, was previously known from southern Japan to the South China Sea, and A. elongatus, from 250-350 m off New Caledonia, previously only from the Madura Sea and northwestern Australia. Arnoglossus macrolophus was collected from relatively shallow waters (49-92 m) off New Caledonia, and A. japonicus and A. polyspilus from deeper waters (210-385 m) off New Caledonia, the Loyalty Islands and Chesterfield Plateau.

Résumé [+] [-]The sequences spanning 307 bp of the mitochondrial cytochrome b gene were determined for 45 sepcimens of Beryx splendens and seven specimens of B. mollis collected in Japan, resulting in identification of 11 and three haplotypes in the two species, respectively. The parsimony tree was constructed from the determined sequences and those registered into the GenBank database as species A and W of B. splendens collected in New Caledonia, featuring with two clades. The first clade comprised species W from New Caledonia and B. mollis in the present study, whereas the second one contained species A from New Caledonia and B. splendens in the present study. These results demonstrate a large geographic distribution for both B. splendens and B. mollis. Some of the haplotypes found in Japan were identical to those of New Caledonia for both B. mollis and B. splendens, suggesting levels of gene flow at the trans-oceanic scale.

Mémoires du Muséum national d'Histoire naturelle 151:449-466, ISBN:2-85653-186-5
Résumé [+] [-]The bothid genus Tosarhombus is reviewed by comparing four species : T. octoculatus Amaoka, 1969, T. smithi (Nielsen, 1964), T. nielseni sp. nov. and T. neocaledonkus sp. nov. A description of the genus is given in addition to descriptions and a key to the four species. T. smithi from the western Indian Ocean is transferred from the genus Engyprosopon based on high numbers of dorsal fin rays, anal fin rays, lateral-line scales and total vertebrae, unsplit parhypural and hypural plates, and the tip of isthmus not extending to the middle part of the lower eye. T. nielseni sp. nov. From Saya de Malha Bank, western Indian Ocean and T. neocaledonicus sp. nov. From the Chesterfield Islands, west of New Caledonia, are described based on several male and female specimens. The former new species is distinguished by having the posterior 2/3 of the body on the ocular side in males colored pale violet, short pectoral fin on the ocular side (1.7-2.0 times in head length), and a long snout and upper jaw on the blind side (4.4-4.7 times and 2.5-2.6 times in head length respectively). The latter new species has a high number of scales in lateral line (more than 80). And the filamentous pectoral fin ray on the ocular side of males.

T. longimanus is characterized by having uniserial teeth on upper jaw, a pectoral fin on the ocular side longer than the head in males, 6 2 - 7 1 scales in the lateral line and a light brownbody. T. brevis is characterized by having a deeper body, a shorter pectoral fin on the ocular side in males and smaller mouth. P.filipes is distinguished from known congeners of the genus by the greatly elongated pelvic fm in males and the small number of scales in the lateral line. P. kiensis and P. coarctatus represent first records from the Coral Sea.

Résumé [+] [-]A new bothid flounder, Engyprosopon marquisensis, is described from 11 specimens collected in deep waters (108-408 m) off the Marquesas Islands (French Polynesia) during the French exploratory cruise MUSORSTOM 9 in 1997. Engyprosopon marquisensis is similar to E. bellonaensis from the Chesterfield Islands and Bellona Plateau in the Coral Sea and E. vanuatuensis from off Vanuatsu Island, but is easily distinguished from E. bellonaensis by the following combination of characters: narrow interorbital space in both sexes, small mouth, short caudal fin, large number of vertebrae, and fewer gill rakers. It differs from E. vanuatuensis by many scales in the lateral line, small eyes, short ocular-side upper jaw, and short blind-side lower jaw. Engyprosopon marquisensis is the deepest occurring (408 m) species of the genus, and constitutes the second species of this genus with an eastern distribution.

Résumé [+] [-]Symphysanodon mona, a new species of perciform fish, is described from a single specimen collected in Mona Passage off the west coast of Puerto Rico. It differs from all other species of Symphysanodon in having fewer gillrakers on the first gill arch (4 or 5 + 19-21 = 24 or 25 total vs. 8-14 + 20-29 = 28-42 total) and, additionally, from the other two Atlantic species of the genus (S. berryi and S. octoactinus) in two other features of gill-arch morphology, viz., in having a ventral branch of the obliquus dorsalis 3 muscle (vs. its absence in the other two species) and in having a posteriorly projecting extension of the cartilaginous lateral end of ceratobranchial 4 (vs. its absence in the other two species; S. berryi has a small accessory cartilage associated with the lateral end of ceratobranchial 4 which may also be present in S. octoactinus). Symphysanodon parini, new species, known from 10 specimens collected over Sala y Gomez Ridge in the eastern South Pacific, can be distinguished from all other species of Symphysanodon, except S. maunaloae from the central and western Pacific, by the following combination of characters: segmented anal-fin rays 7, tubed lateral-line scales 45-50, total gillrakers on first gill arch 31 34 ( 9 or 10 + 22-24), sum of lateral-line scales and gillrakers on individual specimens 77-84, depth of body 22.5-24.7% SL (4.0-4.4 times in SL), length of depressed anal fin 24.8-26.4% SL, hypurals 1&2 autogenous, hypurals 3&4 represented by a single plate, and first caudal vertebra without parapophyses. It is distinguished from S. maunaloae by differences in mean numbers of tubed lateral-line scales (mean = 47.89 for S. parini vs. mean = 44.94 for S. maunaloae) and pectoral-fin rays (mean = 16.90 for S. parini vs. mean = 16.13 for S. maunaloae) and by differences in a few morphometric characters. Symphysanodon rhax, new species, known from specimens collected off the Maldive Islands, northern Indian Ocean, is separable from all other species of Symphysanodon, except S. berryi from the Atlantic, by the following combination of characters: segmented rays in the anal fin 7, tubed lateral-line scales 50, gillrakers on the first gill arch 35-38 (10 or 11 + 25-27), sum of lateral-line scales and gillrakers on individual specimens 85 - 88, depth of body 20.6-24.8% SL (4.0-4.9 times in SL), length of depressed anal fin 21.8-23.9% SL, hypurals 1&2 autogenous, hypurals 3&4 represented by a single plate, and first caudal vertebra without parapophyses. It can be distinguished from S. berryi by its shorter second anal-fin spine and a suite of other morphometric characters. A key to Symphysanodon and a review of the other species of the genus are also presented.

Résumé [+] [-]In May 2014, a group of ichthyologists from the California Academy of Sciences and the Bishop Museum collecting fishes off the coast of Batangas, Luzon, Philippine Islands, obtained, in a depth of ca. 150 meters, four specimens of a species of Grammatonotus previously unknown to science. This new species, Grammatonotus brianne, is distinguishable from its described congeners by the following combination of characters: short anal-fin spines, rhomboid shaped caudal fin, lateral line usually disjunct, and live coloration. Herein we provide characters that distinguish callanthiids from other percoids and that distinguish Grammatonotus from Callanthias, the other genus in the family Callanthiidae, along with the description of the new species and short accounts of two other Grammatonotus, G. crosnieri and G. roseus, from the Coral Triangle.

Résumé [+] [-]Ce catalogue recense les spécimens-types de l'ordre des Gadiformes (sensu Patterson et Rosen, 1989) dans les collections ichtyologiques du Muséum national d'histoire naturelle à Paris (MNHN), du Musée océanographique de Monaco (MOM), de l'Université Claude Bernard de Lyon (UCBL) et du Musée zoologique de Strasbourg (MZS). Plusieurs articles traitant de la phylogénie des Gadiformes sont regroupés dans Cohen (1989). Les Zoarcoidei et les Ophidioidei ont été séparés des Gadiformes (voir Patterson et Rosen, 1989, pour un historique). Les premiers sont maintenant classés dans les Perciformes, les seconds dans un autre ordre de Paracantbopterygies, les Ophidiiformes (Lecointre, 1994: Nelson. 1994). Les catalogues correspondant restent à compiler. Le tableau 1 présente les récentes classifications des Gadiformes que nous avons consultées (Markle in Cohen, 1989; Cohen et al. , 1990; Nelson, 1994). Nous les avons comparées avec celles qui sont données par Eschmeyer (1990, 1998). Elles se recouvrent très largement, abstraction faite du niveau taxinomique des catégories utilisées. Markle les élève presque toutes au rang familial; Cohen et al. Ne distinguent ni les Steindachneriinae ni les Ranicipitinae; par rapport à Cohen et al. (1990), Eschmeyer (1990) incluait les Parabrotulidae dans les Gadiformes ( 1990), mais les place aujourd'hui dans les Ophidüdae (Ophidiiformes) (1998) comme les autres auteurs. Et élève les Phycinae et les Lotinae au rang familial. Néanmoins, la définition des Lotidae et des Phycidae varie d'un auteur à l'autre (Tableau Il). La liste des Gadiformes actuels est en grande partie donnée dans Cohen et al. (1990). Les Gadiformes et les Pleuronectiformes sont les deux grands ordres de Poissons qui n'ont pas été revus par Cuvier et Valenciennes dans leur monumental travail ( 1829- 1849). La liste des exemplaires historiques de l' annexe A comprend seulement des exemplaires conservés en herbier. Provenant de Risso et d' Adan son, ainsi que quelques exemplaires anciens conservés en alcool. Les types d'herbier de Risso avaient été revus par Bertin (1945). Les types des espèces de Macrouridae décrites par Vaillant en 1888 (Expéditions scientifiques du "Travailleur" et du "Talisman") avaient été revus par Bauchot et al. (1972). Nous avons intégralement repris leurs conclusions. Certains des types de Moridae ont été revus par Cohen en 1964 et 1966, et par Paulin en 1989.

Résumé [+] [-]On evolutionary timescales, sea level oscillations lead to recurrent spatio-temporal variation in species distribution and population connectivity. In this situation, applying classical concepts of biogeography is challenging yet necessary to understand the mechanisms underlying biodiversity in highly diverse marine ecosystems such as coral reefs. We aimed at studying the outcomes of such complex biogeographic dynamics on reproductive isolation by sampling populations across a wide spatial range of a species-rich fish genus: the sergeants (Pomacentridae: Abudefduf). We generated a mutlilocus data set that included ten morpho-species from 32 Indo-West Pacific localities. We observed a pattern of mito-nuclear discordance in two common and widely distributed species: Abudefduf sexfasciatus and Abudefduf vaigiensis. The results showed three regional sublineages (Indian Ocean, Coral Triangle region, western Pacific) in A. sexfasciatus (0.6–1.5% divergence at cytb). The other species, A. vaigiensis, is polyphyletic and consists of three distinct genetic lineages (A, B and C) (9% divergence at cytb) whose geographic ranges overlap. Although A. vaigiensis A and A. sexfasciatus were found to be distinct based on nuclear information, A. vaigiensis A was found to be nested within A. sexfasciatus in the mitochondrial gene tree. A. sexfasciatus from the Coral Triangle region and A. vaigiensis A were not differentiated from each other at the mitochondrial locus. We then used coalescent-based simulation to characterize a spatially widespread but weak gene flow between the two species. We showed that these fishes are good candidates to investigate the evolutionary complexity of the discrepancies between phenotypic and genetic similarity in closely related species.

Résumé [+] [-]Two sibling species, Beryx mollis and B. splendens, are potentially the main fish species of commercial interest for a bottom-line fishery in the deep waters of New Caledonia’s EEZ. Two datasets, morphological and meristic (one from Japan, the other one from New Caledonia) were obtained from specimen samples of the two species, which were species-identified by either the number of pyloric caeca (which allows total discrimination of the two species), or DNA markers, or a posteriori by the outcome of principal component analysis (PCA). Four morphological variables were measured (body height, head length, snout length, orbit diameter) and transformed to take standard length into account. None of these morphological variables, either single or combined to another, allowed sufficient discrimination between the two species. PCA on the four morphological variables led to a slightly better result, but still insufficient. Six meristic variables were utilized (numbers of soft rays in the dorsal, pectoral, pelvic, and anal fins, number of branchiospines on the lower half of the first branchial arch, number of scales on the lateral line). All these variables except the number of scales on the lateral line, proved useful to statistically distinguish the two species. However, none was diagnostic when taken separately from the other variables and the combination of two variables was only slightly better for this purpose. Canonical discriminant analysis helped determine which meristic characters could be used in priority to identify individuals: these were the numbers of soft rays on the dorsal, pectoral, and pelvic fins, and the number of branchiospines. In practice, if the fish is disembowelled or filetted, it takes only counting the number of pyloric caec for identification to species. If the fish is preserved whole before being marketed, then we recommend to count the numbers of soft rays on the dorsal, pectoral, and pelvic fins for a reasonably reliable identification.

Résumé [+] [-]Two new species of the parasitic copepod genus Dissonus Wilson, 1906 are described: D. excavatus n. sp. from the gills of a labrid, Bodianus perditio, and a lutjanid, Macolor niger, collected off New Caledonia and Taiwan, and D. inaequalis n. sp. from a hemiscylliid elasmobranch, Chiloscyllium punctatum, collected off Sarawak (Malaysia) and the Philippines. Material of D. heronensis Kabata, 1966 is described from a balistid host, Pseudobalistes fuscus, off New Caledonia, and this constitutes a new host record for this parasite. D. manteri Kabata, 1966 was collected from four serranid host species off New Caledonia and from one of the same hosts off Taiwan. Two of the hosts from New Caledonia, Plectropomus laevis and Epinephelus cyanopodus, represent new host records. D. pastinum Deets & Dojiri, 1990 was recognised as a new synonym of D. nudiventris Kabata, 1966, so the total number of valid species is now twelve. Material from museum collections of D. nudiventris, D. similis Kabata, 1966 and D. spinifer Wilson, 1906 was re-examined and provided new information which is utilised in a key to all valid species of Dissonus.

Résumé [+] [-]Flatfishes (Pleuronectiformes) are a species‐rich and distinct group of fishes characterized by cranial asymmetry. Flatfishes occupy a wide diversity of habitats, including the tropical deep‐sea and freshwaters, and often are small‐bodied fishes. Most scientific effort, however, has been focused on large‐bodied temperate marine species important in fisheries. Phylogenetic study of flatfishes has also long been limited in scope and focused on the placement and monophyly of flatfishes. As a result, several questions in systematic biology have persisted that molecular phylogenetic study can answer. We examine the Pleuronectoidei, the largest suborder of Pleuronectiformes with >99% of species diversity of the order, in detail with a multilocus nuclear and mitochondrial data set of 57 pleuronectoids from 13 families covering a wide range of habitats. We combine the molecular data with a morphological matrix to construct a total evidence phylogeny that places fossil flatfishes among extant lineages. Utilizing a time‐calibrated phylogeny, we examine the timing of diversification, area of origin and ancestral temperature preference of Pleuronectoidei. We find polyphyly or paraphyly of two flatfish families, the Paralichthyidae and the Rhombosoleidae, and support the creation of two additional families—Cyclopsettidae and Oncopteridae—to resolve their non‐monophyletic status. Our findings also support the distinctiveness of Paralichthodidae and refine the placement of that lineage. Despite a core fossil record in Europe, the observed recent diversity of pleuronectoids in the Indo‐West Pacific is most likely a result of the Indo‐West Pacific being the area of origin for pleuronectoids and the ancestral temperature preference of flatfishes is most likely tropical.

Scolecenchelys Ogilby, previously a subgenus of Muraenichthys Bleeker, is generically distinct on the basis of differences in dentition (teeth conical and uniserial or biserial vs blunt and multiserial), cephalic pores (2 pores between anterior and posterior nostrils vs 1 pore), and its posterior nostril condition (within vs outside mouth). Valid species of Muraenichthys and Scolecenchelys and their synonyms are identified.

Résumé [+] [-]Rhodopsin mediates an essential step in image capture and is tightly associated with visual adaptations of aquatic organisms, especially species that live in dim light environments (e.g., the deep sea). The rh1 gene encoding rhodopsin was formerly considered a singlecopy gene in genomes of vertebrates, but increasing exceptional cases have been found in teleost fish species. The main objective of this study was to determine to what extent the visual adaptation of teleosts might have been shaped by the duplication and loss of rh1 genes. For that purpose, homologous rh1/rh1-like sequences in genomes of ray-finned fishes from a wide taxonomic range were explored using a PCR-based method, data mining of public genetic/genomic databases, and subsequent phylogenomic analyses of the retrieved sequences. We show that a second copy of the fish-specific intron-less rh1 is present in the genomes of most anguillids (Elopomorpha), Hiodon alosoides (Osteoglossomorpha), and several clupeocephalan lineages. The phylogenetic analysis and comparisons of alternative scenarios for putative events of gene duplication and loss suggested that fish rh1 was likely duplicated twice during the early evolutionary history of teleosts, with one event coinciding with the hypothesized fish-specific genome duplication and the other in the common ancestor of the Clupeocephala. After these gene duplication events, duplicated genes were maintained in several teleost lineages, whereas some were secondarily lost in specific lineages. Alternative evolutionary schemes of rh1 and comparison with previous studies of gene evolution are also reviewed.

Résumé [+] [-]The large-eye seabreams or Monotaxinae is one of two subfamilies in the Lethrinidae, a family of perch-like coral reef fishes. Despite its widespread occurrence and its commercial interest in the tropical Indo-West Pacific (IWP), this subfamily has traditionally been considered a taxonomically difficult group. Based on 268 samples collected from all 15 known large-eye seabream species throughout their distribution ranges, we investigated the taxonomic diversity and phylogenetic relationships in the subfamily. From the results of multiple analyses on four gene markers, we confirmed the monophyly of all four genera in the subfamily (Gnathodentex, Gymnocranius, Monotaxis and Wattsia). We confirmed the occurrence of two species in the genus Monotaxis. We reported 15 delimited species within the most speciose genus Gymnocranius, four of which are potentially new species. The time-calibrated phylogenetic reconstruction enabled us to clarify the evolutionary history of the large-eye seabreams and to infer past patterns of species distribution. The most recent common ancestor to the Monotaxinae likely occurred in the central IWP ca. 32 million years ago. A burst of species diversification likely took place during the Mid- to Late Miocene, coinciding with tectonic change in the central IWP region. This gave rise to most extant lineages in Gymnocranius. The observed geographic distribution patterns in the subfamily most likely point to the central IWP as the area of origin and diversification. This was followed by multiple events of centrifugal range expansion towards either the Indian Ocean or the western Pacific Ocean, or both. Our results thus provide new support for S. Ekman’s center-of-origin hypothesis.

Résumé [+] [-]The new waspfish Ocosia dorsomaculata n. sp. (Tetrarogidae) is described, based on specimens from Australia (5) and New Caledonia (51). Although O. dorsomaculata and Ocosia apia Poss & Eschmeyer 1975 both share modally XVI, 8 dorsal-fin rays with a long second dorsal-fin spine, and presence of supraocular, lateral lacrimal, and suborbital spines, the former has modally 13 pectoral-fin rays (vs. usually 12 in the latter), a lower modal count of total gill rakers (10 vs. 16–18), greater upper-jaw length, greater third to sixth dorsal-fin spine lengths, the third dorsal-fin spine slightly shorter than the second dorsal-fin spine (vs. third spine markedly shorter than second spine), 1 or 2 prominent pale brown to dark brown blotches on the membrane between the fifth to eighth or sixth to ninth dorsal-fin spines (vs. 1 blotch on the membrane around the third dorsal-fin spine and 1 blotch on the membrane between the sixth to eighth dorsal-fin spines), and body with 11–15 longitudinal pale brown to dark brown bars along lateral line (vs. irregular brown specks). A key to the species of Ocosia is given.

Résumé [+] [-]Deep-sea fishes have been poorly sampled globally, and overall knowledge of demersal fish distributions and the drivers of community composition and diversity remain limited. Here, we used nine comparable datasets with specieslevel identification of fishes from research surveys around the world to test the hypothesis that deep-sea demersal fish assemblage composition on seamounts is consistent between major oceans. Two levels of analysis were undertaken: the first combined all presence-absence data from a seamount, while a second more detailed analysis included catch weight data based on a smaller number of seamounts. Overall, there was a consistent separation of seamounts by region based on the compositions of their fish assemblages. New Zealand and SE Australian seamounts have a very similar ichthyofauna, which differs substantially from seamounts in the eastern South Pacific Ocean off Chile. In the North Atlantic, Bear Seamount appears to be distinct from all others, while seamount fish assemblages off Ireland, the Azores, and Faraday Seamount have some affinities. The Tasman Sea and New Caledonian seamounts show strong intra-regional variation. On an ocean basin scale we therefore reject the hypothesis that the composition of deep-sea demersal fish fauna is homogeneous globally. However, regional patterns of both species composition and relative abundance show some similarities between widely separated geographical locations, especially where orange roughy is a dominant species. Salinity was the main environmental factor identified in a multivariate analysis of environmental covariate data. This is likely to be a result of salinity being a key characteristic defining both Antarctic Intermediate Water and North Atlantic Deep Water, the water masses found over most seamounts examined in this study, and which may explain similarities between deep-sea fish assemblages.

Résumé [+] [-]Narcine lasti, n. sp., is described from abundant material mostly collected from the Western Australian coast. The new species is distributed from Green Head and the Houtman Abrolhos in the eastern Indian Ocean to southeastern Indonesia in the Arafura Sea, along the upper continental slope. Narcine lasti is distinguished by a unique combination of characters including a tail length much longer than disc width or length, uniform yellowish-brown to yellowish-pink dorsal colouration that also extends anteriorly over preorbital snout region, lateral tail folds low and ridge-like, disc width and length with means of 40.3 and 42.1 % of total length (TL) respectively, nasal curtain much wider than long, and preorbital snout length over 10 % of TL. Narcine lasti is most similar to N. tasmaniensis and another undescribed species of Narcine from off the Queensland coast of Australia. All three species have relatively similar proportions and dorsal colouration, but can be distinguished on the basis of preorbital snout length, disc width and length, lateral tail fold morphology and usually also in dorsal colouration. Narcine lasti is easily distinguished from Narcine westraliensis McKay, 1966, the only other species of the genus in Western Australia, by many features including disc shape, relative proportions of the tooth bands, and in dorsal colouration. Both species do not co-occur, as N. westraliensis is distributed on the continental shelf in relatively shallow waters, while N. lasti is confined to deeper waters of the continental slope.

Résumé [+] [-]A new species of lanternshark, Etmopterus alphus (Squaliformes: Etmopteridae), is described from the south-western Indian Ocean. The new species resembles other members of the ‘Etmopterus lucifer’ clade in having linear rows of dermal denticles and most closely resembles E. molleri from the south-western Pacific. The new species is fairly common along the upper continental slopes off central Mozambique, at depths between 472 and 558 m, and is also found on the southern Madagascar Ridge in 650–792 m depth. It can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including arrangement of flank and caudal markings, dimension of flank markings and shape, size and arrangement of dermal denticles along the body. Molecular analysis further supports the distinction of E. alphus from other members of the E. lucifer clade.

(Selachii, Scyliorhynidae) from the South Pacific Ocean, with a Revision of the Diagnosis of the Order, Family, and Genus and Notes on Descriptive Terminology of Microtriches. The Journal of Parasitology 86(5): 1078-1084. DOI:10.2307/3284826
Résumé [+] [-]Ditrachybothridium piliformis is a new species from the spiral intestine of a cat shark, Galeus sp., from the southern Pacific Ocean. This is only the second species assigned to Ditrachybothridium. It differs from the type species D. macrocephalum in lacking spines on the scolex, a character originally used to diagnose the genus. The diagnoses of the Ditrachybothridiidae and of Ditrachybothridium have been revised to reflect this difference. This new species is further differentiated from the type species in its possession of pectinate spinitriches on the tegument of the scolex. The holdfast structures of this species are weakly muscularized, with no membrane-bound layer of radial muscles, indicating that the holdfast structures are bothria rather than bothridia as described in the most recent literature. Several reports for other species have indicated the same situation in other diphyllideans. The diagnosis of the order has been revised to reflect this finding.

Résumé [+] [-]An integrated taxonomic approach, combining both morphological and molecular data, was adopted to investigate the Hydrolagus lemures-ogilbyi group in the Indo-Australian region. Single mitochondrial markers (CO1 and NADH2) provided evidence supporting the separation of four distinct species in this group. However, detailed morphological data collected from specimens from across their range failed to find any consistent differences, and many features previously considered to be diagnostic were found to be variable. Nuclear DNA data also failed to support the differences found with the single mitochondrial markers and, together with the morphological data, supported the hypothesis that only a single species in this group is present in the Indo-Australian region. In addition, the results failed to support the current generic placement of this group in Hydrolagus, suggesting they belong to the genus Chimaera with doubt over the validity of Hydrolagus as a valid genus. The oldest available name for this group is Chimaera ogilbyi and a redescription is provided. This species occurs throughout Australia, eastern Indonesia (Java, Bali, and Lombok) and northern Papua New Guinea.

Résumé [+] [-]An annotated checklist of the fish species of the Madagascar EEZ (southwestern Indian Ocean) comprises a total of 1,798 species in 247 families. 158 species are recorded from Madagascar for the first time. The majority of the species is autochthonous; 28 species have been introduced, mainly in freshwater habitats. The fish fauna is mostly marine (95.4% of the total number of native fish species), with the Gobiidae, Labridae, Serranidae, Pomacentridae and Apogonidae being the families with most representatives; among the 90 native freshwater fish species (adults mainly occurring in freshwater), the Cichlidae are the dominating family, but there are also two endemic families, the Bedotiidae (16 species) and Anchariidae (6 species). The fish fauna at Madagascar is typical for offshore, high islands in the southwestern Indian Ocean. Zoogeographically, the main element of the marine fish fauna of Madagascar consists of widespread tropical Indo-Pacific species (978 species, 58.3% of the total native marine species). A total of 13 species (3.3%) are found worldwide, either circumtropical or circumtropical including warm temperate zones. A total of 215 species (12.8%) are found worldwide, either circumtropical or circumtropical including warm temperate zones. An additional 453 species (27.0%) are Indian Ocean endemics, including 233 western Indian Ocean endemics (13.9%), 73 southwestern Indian Ocean endemics (4.4%), 16 species endemic to Madagascar and Mascarenes (1.0%), 4 species endemic to Madagascar and Comoros (0.2%), 3 species endemic to Madagascar and Madagascar Ridge (0.2%), and 37 marine species endemic to Madagascar (2.2%). Most of the autochthonous freshwater fishes are endemic to Madagascar (87 species, 96.7% of the native freshwater species).

Résumé [+] [-]Descriptions of three new species of the aulopid genus Hime from the central and western Pacific and presumably the easternmost Indian Ocean are presented. Hime surrubea sp. nov., confined to the Hawaiian Island region, has been misidentified in species accounts and faunal lists as H. japonica and although resembling it is separable from that species by its shorter caudal peduncle, slightly larger head, larger eye, especially relative to head size, and slightly smaller pectoral and pelvic fins. Hime capitonis sp. nov. is known conclusively only from seamounts off the southern tip of New Caledonia and Vanuatu, and is distinguishable by its distinctively large head (32.3–35.6% SL) and eyes (orbital diameter 10.8–13.0% SL) and relatively few scales between the anus and anal fin origin (7–9). The Indonesian H. caudizoma sp. nov. is so far known from only 8 specimens, acquired in markets in southeastern Lombok and presumably caught nearby in what would be regarded the eastern reaches of the Indian Ocean. The species is recognisable by its dorsal fin of rather uniform moderate height with nearly straight distal margin and 17 rather than 16 rays, none of which is filamentous in either sex, the second penultimate ray rather than anterior rays the longest in males. Like the other two described here, H. caudizoma has among the largest head and eyes of the family. Observations on the dorsal fin form and other features of H. microps Parin & Kotlyar, 1989 are provided based on a large male specimen collected at Rapa Iti, Austral Islands and a re-evaluation of the original description.

Résumé [+] [-]Il existe de nombreux monts sous-marins à l'intérieur de la Z.E.E de Nouvelle Calédonie. Certains d'entre eux ont déjà fait l'objet d'une cartographie simplifiée et de deux campagnes exploratoires de chalutage, l'une japonaise en 1980, l'autre française (ORSTOM) en 1986. Au cours de ces campagnes, les prélèvements furent réalisés entre 220 et 690 m de profondeur, de jour et de nuit, avec des chaluts de dimensions différentes. Les captures rapportées à la surface de fond échantillonnée varièrent de 8 à 1429 kg/hectare en fonction de la taille de l'engin, de la profondeur et de l'heure du prélèvement. Les pêches de nuit s'avérèrent beaucoup plus productives que celles de jour. Au-delà de 500 m, la composition spécifique de l'ichtyofaune changeait totalement. Une évaluation très grossière permet d'estimer à plusieurs milliers de tonnes de poissons par an la P.M.S de la totalité de la Z.E.E. Une cartographie détaillée de la zone mériterait d'être réalisée pour servir de base à des prospections halieutiques plus poussées.

Résumé [+] [-]Within the framework of the programme "ZoNéCo" of evaluation of the marine resources of the economic zone of New Caledonia, a series of operations were completed in the southeastern part of Ihe economic zone. The first was a balhymetrical and geophysical survey of the major part of the Norfolk Ridge and the southem end of Ihe Loyalty Ridge. The data obtained on this survey provided a base for the preparation and completion of the deep-sea trawling survey "HALIPRO 2", the main objective of which was 10 search for commercial quantities of deep-sea fish, primarily orange roughy (Hoplostethus atlanticus). During this survey, 106 hauls were made between 230 and 1,860 m depth. A total catch of 263 fish species was made belonging to 192 genera and 101 families. In particular, 37 species of sharks and rays were collected of which 40% are new to science. The results confinn the extreme specific richness of the deep-sea ichthyofauna and the presence of species of commercial interest such as the alfonsino, Beryx splendens. However, orange roughy, was not located.

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification. Frontiers in Marine Science 8: 749078. DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

Résumé [+] [-]Studies of recent bathyal collections mainly made during MUSORSTOM cruises have shown an extremely diverse grenadier fauna in the New Caledonian region. A total of 932 grenadier specimens (families Bathygadidae and Macrouridae) representing 49 species in 16 genera were collected from 102 samples taken from depths between 395 and 2105 m (mid-depth sounding). Of the 49 species, 15 (31%) were found to be new (one recently described) and two are treated as indeterminate. The collections were dominated by the genera Caelorinchus (14 spp., 5 new), Ventrifossa (7 spp., 2 new, but one not named), Hymenocephalus (sensu lato) (7 spp., 2 new), and Nezumia (5 spp., 3 new). This paper reports the taxonomic findings on the collections. A subsequent paper will report on aspects of the distribution and biology of grenadiers in the New Caledonian region.

Iwatsuki Y., Akazaki M. & Taniguchi N. 2007. Review of the species of the genus Dentex (Perciformes: Sparidae) in the western Pacific defined as the D. hypselosomus complex with the description of a new species, Dentex abei and a redescription of Evynnis tumifrons. Bull. Natl. Mus. Nat. Sci., Ser. A, Suppl 1: 29–49
Résumé [+] [-]The lectotype of Chrysophrys tumifrons designated by Boeseman (1947) is a specimen of the species currently recognized as Evynnis japonica Tanaka, 1931. The name is, therefore, the senior synonym for that species. Dentex spariformis Ogilby, 1910, based on specimens collected at Moreton Island, Queensland, Australia, is redescribed and resurrected as a valid species, having previously been synonymized with D. tumifrons (Temminck and Schlegel, 1843). Dentex abei sp. Nov. Is described from ten type and 30 non-type specimens collected in the Ryukyu Islands, Chichi-jima of Ogasawara Islands (=Bonin Islands), Japan, and Luzon Island, Philippines. These two Dentex species, together with D. hypselosomus Bleeker, 1854 and D. fourmanoiri Akazaki and Séret, 1999 are recognized as a “Dentex hypselosomus complex” and reviewed on the basis of western Pacific and southern Indonesian material. Dentex hypselosomus differs from the others in having three eye-sized fluorescent yellow blotches dorsally, plus a small yellow spot posteriorly on the soft dorsal fin base (vs. Small bright cobalt or blue-spotted lines on the body in D. abei and no spots in D. fourmanoiri and D. spariformis) and deeper suborbital depth. Dentex fourmanoiri differs from D. spariformis in having 13 dorsal fin spines and 9 soft dorsal fin rays (vs. 12 spines and 10 rays). Dentex spariformis has a larger eye than D. abei and D. hypselosomus (mean orbit diameter 2.78 in head length vs. 3.66 and 3.32, respectively). Although none of the four species have been recorded in the equatorial zone, D. abei and D. hypselosomus are allopatric in the Northern Hemisphere, while D. spariformis and D. fourmanoiri are allopatric in the Southern Hemisphere, too. A key to the complex is provided.

Résumé [+] [-]A new species of pinguipedid fish, Parapercis nigrodorsalis, is described from 17 specimens collected off the North Island of New Zealand and Wanganella Bank, Norfolk Ridge, Tasman Sea, in depths of 56–280 m. The species has also been photographed underwater off the Poor Knights Islands Reserve and Burgess Island, Mokohinau Group, in New Zealand. It is most similar to Parapercis binivirgata (Waite, 1904) in morphology, coloration and meristic values, but is unique among the genus in having a combination of dorsal-fin rays V, 23, anal-fin rays I, 19, lateral-line scales 57–63, vomer with 1–2 irregular rows of robust conical teeth, palatines with 1–2 rows of small teeth, angle of subopercle smooth, 10 abdominal and 22 caudal vertebrae, and coloration, including seven broad reddish-brown bands on the upper body between the spinous dorsal-fin and the caudal peduncle, most bands bifurcated into close-set double bars with black smudge-like blotches below, and membrane of the spinous dorsal fin black. Comparison of the mitochondrial cytochrome c oxidase subunit 1 (CO 1) genetic marker utilised in DNA barcoding produced a genetic divergence of 5.38% and 7.63% between the new species and its two closest sampled congeners. The holotype of P. binivirgata is identified from two specimens previously regarded as syntypes, some revisions are made to meristic data in the original description of the latter, and a detailed description of the revised geographic range of P. binivirgata is provided.

Résumé [+] [-]Three valid species of Parabembras are recognized: P. curta, P. robinsoni, and the new species P. multisquamata. Parabembras robinsoni from the southwestern Indian Ocean (South Africa to Mozambique) is easily distinguishable from the other species in having eleven spines in the first dorsal fin, a distinct symphyseal knob on the lower jaw, two preocular spines, and a single lachrymal spine. Parabembras multisquamata from the southwestern Pacific (Vanuatu, Papua New Guinea) and the Philippines, and P. curta, known from the northwestern Pacific (southern Japan to South China Sea), are similar in sharing the absence of a symphyseal knob on the lower jaw, the presence of two lachrymal spines, and a single preocular spine, but the former is clearly distinguished from the latter in usually having 10 spines in the first dorsal fin (vs. eight or nine spines in P. curta), 9–11 supraocular spines (vs. 6–8 in P. curta), 40–44 pored lateral line scales (vs. 34–39 in P. curta), and the pectoral fin extending beyond the level of the anus (vs. not reaching to the level of the anus in P. curta).

Résumé [+] [-]The Indo-Pacific peristediid genus Scalicus Jordan 1923 is taxonomically revised with six species including a single new species: Scalicus engyceros (Günther 1872), Scalicus hians (Gilbert and Cramer 1897), Scalicus orientalis (Fowler 1938), Scalicus paucibarbatus sp. nov., Scalicus quadratorostratus (Fourmanoir and Rivaton 1979) and Scalicus serrulatus (Alcock 1898). The new species differs from its congeners in having a stick-like rostral projection with ball-like fleshy mass at the tip, rostral projection width 2.12–4.60 in rostral projection length; 4 lip and 3 chin barbels; 8–11 branches on filamentous barbel; filamentous barbel lacking membrane between its each branch, its length 13.1–20.4% of standard length; posteriormost chin barbel simple (rarely divided into two branches at the base); and presence of antrorse spines on posterior bony plates of upper lateral row. It is clear that Scalicus amiscus (Jordan and Starks 1904) and Scalicus investigatoris (Alcock 1898) are junior synonyms of S. hians, respectively, and Scalicus gilberti (Jordan 1921) is a junior synonym of S. engyceros. A key to the species of Scalicus is presented. In addition, lectotypes are designated for S. hians, S. quadratorostratus and S. serrulatus, respectively.

Résumé [+] [-]A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduced species. The native fi sh fauna of New Caledonia therefore consists of 2320 species in 241 families. The largest families are the Gobiidae, Labridae, Pomacentridae, Serranidae, Apogonidae, Blenniidae, Macrouridae, Myctophidae and Muraenidae. The freshwater fi sh fauna is dominated by the families Gobiidae, Eleotridae, Anguillidae and Mugilidae. A total of 61 species represent new records from New Caledonia. The fish fauna from New Caledonia includes a total of 125 species occurring in freshwater (plus eight introduced species), 266 (plus two introduced) species in transitional (brackish) waters, and 2320 marine species. The detailed geographical distribution of the New Caldonian fi sh species including the southern submarine ridges (Lord Howe Island, Norfolk Island, New Zealand) is provided. Among the New Caledonian marine species, 905 are recorded from the East Coral Sea including Chesterfi eld Islands, 193 from the New Caledonian basin, 1860 from the Grande Terre group, 85 from the Norfolk Ridge, and 1029 from the Loyalty Ridge including Loyalty Islands. New Caledonia has a considerable endemic element of 107 species (4.6 % of the total native species).

Résumé [+] [-]A new species of spurdog, Squalus bucephalus sp. nov., is described from deepwater south of New Caledonia in the northern Tasman Sea. It belongs to the ‘megalops-cubensis group’ but differs from Australian forms of S. megalops in having a broader head, larger dorsal-fin spines and reaches a larger adult size. It also differs in several other meristic and morphometric details and is the only Squalus known to possess both unicuspid and multicuspid denticles in adults. It is morphologically similar to the newly described S. crassispinus from the eastern Indian Ocean, but differs in having a lower, strongly raked first dorsal fin, more vertebrae, and more slender dorsal-fin spines.

Last P.R. & Séret B. 2008. Three new legskates of the genus Sinobatis (Rajoidei: Anacanthobatidae) from the Indo–West Pacific. Zootaxa 1671: 33-58
Résumé [+] [-]Three new species of legskates (Anacanthobatidae) are described from the Indo–Australian region. Two of these species conform to the subgenus Sinobatis Hulley of Anacanthobatis von Bonde & Swart, which is herein elevated to genus level based primarily on clasper morphology. Sinobatis presently includes S. borneensis (South China Sea and Taiwan) and possibly S. melanosoma (East and South China Seas and Taiwan), as well as the new species, S. bulbicauda sp. Nov. (eastern Indonesia and northwestern Australia, SE Indian Ocean) and S. filicauda sp. Nov. (northeastern Australia, SE Pacific Ocean). The third new species, S. caerulea sp. Nov. (northwestern Australia, SE Indian Ocean), is provisionally placed in Sinobatis in the absence of an adult male. The new species are distinguishable from each other, and from nominal Indo–Pacific legskates, based on their morphometrics, meristics, tail morphology and coloration. Legskates exhibit marked intraspecific variation in shape associated with their soft, flexible bodies, and considerable ontogenetic and sexual differentiation.

Résumé [+] [-]Members of the benthopelagic fish family Euclichthyidae, also known as the Eucla cods, occur on the upper continental slopes off Australasia at 220–1040 m depths. Euclichthyids essentially differ from other gadiform fishes in a combination of two almost contiguous dorsal fins with the second much longer based, a deeply notched anal fin with its anterior portion greatly elevated, jugular pelvic fins consisting of 3 partly united filiform upper rays and 3 free filamentous lower rays, an asymmetrical caudal fin with 5 hypurals fused into two plates, and no chin barbel, or vomerine and palatine tooth patches. Additional characters attributed to the group by other published studies include: no horizontal diaphragm within the posterior chamber of the swim bladder, no swim bladder-auditory capsule connection, presence of a luminous organ, and cranial muscle adductor arcus palatini divided by a strong ligament running from the lateral ethmoid and palatine to the medial face of the hyomandibular. Widely considered to be monotypic since its erection in 1984, the group consists of a single genus and three allopatric species, Euclichthys polynemus McCulloch, 1926 (Western and southern Australia, New Zealand), and two new taxa, E. microdorsalis sp. nov. (northeastern Australia) and E. robertsi sp. nov. (eastern Australia and New Caledonia). Eucla cods are morphologically conservative with both new species superficially resembling the type species, E. polynemus. Euclichthys microdorsalis sp. nov. is the most anatomically and morphologically divergent member of the group in having a shorter first dorsal fin, longer snout, relatively small eye compared to its interorbital width, and fewer caudal-fin rays and primary rakers on the outer gill arch than its congeners. Euclichthys robersti sp. nov. differs from E. polynemus in being smaller with a more slender head, and having a smaller eye, longer anal-fin base and tail, smaller scales, fewer primary rakers on the outer gill arch, more elongate oval otoliths, and usually having a X and/or Y bone in the caudal skeleton (both absent in other Euclichthys). Little is known of their biology but available material suggest that early juveniles remain pelagic in the open ocean with adults benthopelagic near the sea floor. Diagnoses and a key are provided for the three species.

Lee S.H., Lee M.Y., Matsunuma M. & Chen W.J. 2019. Exploring the Phylogeny and Species Diversity of Chelidoperca (Teleostei: Serranidae) From the Western Pacific Ocean by an Integrated Approach in Systematics, With Descriptions of Three New Species and a Redescription of C. lecromi Fourmanoir, 1982. Frontiers in Marine Science 6: 465. DOI:10.3389/fmars.2019.00465
Résumé [+] [-]With 11 species, the genus Chelidoperca is a small group of teleost fishes belonging to the Serranidae. They are bottom-dwelling fishes living on continental shelves/slopes in offshore areas or on remote seamounts/banks at depths ranging from around 40–400m mostly in the tropical Indo-West Pacific. Over the past few years, efforts have been made to resolve the taxonomy of Chelidoperca, and subsequently four new species were described. However, these recent advances were made with a traditional approach (i.e., morphology) and limited examinable materials, usually preserved specimens, from ichthyological collections. Further investigations are still needed to address the gaps in our knowledge about their diversity, phylogeny, and biogeography. In this study, we collected 65 new samples, mainly during eight biodiversity expeditions carried out between 2007 and 2016 in the West Pacific under the Tropical Deep-Sea Benthos program. Specimens were photographed after collection to record fresh color patterns, which are essential for species diagnosis. Our analytical approach includes state-of-the-art DNA-based methods for species delimitation. The combined evidence from both molecular and morphological examinations, as well as other information such as geography, is used to test species validity. This reveals 15 species, including six new ones. We formally describe herein C. leucostigmata sp. nov., C. microdon sp. nov., and C. barazeri sp. nov. on the basis of specimens collected on Macclesfield Bank in the South China Sea, on the Chesterfield and Island of Pines plateau of New Caledonia, and off the New Ireland Province of Papua New Guinea, respectively. These new species are morphologically distinct from all other known species of Chelidoperca by body color pattern and combinations of a few identified characters. We also redescribe one of the lesser known species, C. lecromi, from fresh specimens collected close to its type locality and a new site in the Coral Sea. The distributional records for this and other known species are updated accordingly. Genetic references of the species as well as an updated identification key to western Pacific species are also provided.

Résumé [+] [-]Commercial and scientific bottom longline catches of alfonsino, Beryx splendens, from seamounts off New Caledonia were sampled to study length-frequency distributions. A total of 14,674 fish were measured. CPUE of Beryx splendens on two seamounts is modelled in terms of length and depth.The data show that mean length increases with depth; this is well described by a bivariate normal modelthat estimates catch for a given seamount. In addition, the data show that mean length also varies with the depth of the top of seamounts ; this is described by a recursive model that is designed to predict approximate catch for any seamount. The limitations of both models are discussed, particularly with regard to temporal variation.

Résumé [+] [-]The reproductive biology of the alfonsino Beryx splendens was studied by histological examinations, gonadosomatic index and macroscopic scales of maturation of a large sample of gonads. Alfonsino is a gonochoric species. The size-frequency distribution of the sex ratio was bimodal and considered to be due to size dimorphism. In New Caledonia, the breeding period of this species occurs during the southern summer, with a peak in December to January. The spawning stage is attained at a minimum fork length of 28 cm for females and 33 cm for males. The size at which 50% of the population attain sexual maturity (FL50) is 33.2 cm for females and 34.5 cm for males. Maximum potential fecundity is estimated to lie between 270 000 to 675 000 eggs for ®sh between 34 and 40 cm in fork length. It was possible to differentiate vegetative zones, in which juvenile alfonsino grow until they reach maturity, from reproductive zones (®shing grounds) which are inhabited by mature individuals. The larvae and juveniles could be carried from the reproductive zone to the vegetative zone by currents in an oceanic eddy system.

Résumé [+] [-]A new scorpionfish, Ebosia saya sp. nov. (Scorpaenidae: Pteroinae), is described on the basis of 10 specimens collected from the Saya de Malha Bank in depths of 95–126 m. Comparisons with two valid Indo-Pacific species, Ebosia bleekeri (Döderlein in Steindachner and Do¨derlein 1884) (western Pacific Ocean) and Ebosia falcata Eschmeyer and Rama-Rao 1978 (northern and eastern Indian Ocean), showed E. saya to be most similar to the latter, with both species sharing 8 (usually) anal-fin soft rays, 17 (usually) pectoral-fin rays, the elongated parietal spine of males relatively narrow and strongly falcate posterodorsally, and the pectoral fin predominantly yellow in males, whereas E. bleekeri has 7 (usually) anal-fin soft rays, 16 (usually) pectoral-fin rays, the elongated parietal spine of males relatively broad and weakly falcate, and the pectoral fins entirely red in males. However, E. saya differs from E. falcata in having 5 scale rows above the lateral line [vs. 4 or 5 (modally 4) in E. falcata], slightly greater total numbers (5–20, mean 12.3) of preocular, supraocular, and postocular spines at 60–90 mm SL (vs. 4–18, 8.4), shorter postorbital length 18.1–19.2 (mean 18.7) % SL [vs. 19.8–23.5 (21.5) % SL], and the blotch above the pectoral-fin base and blotches on the pectoral-fin membrane all relatively smaller. Fresh coloration of E. falcata is described for the first time, based on specimens from the Andaman Sea (easternmost record for the species).

Résumé [+] [-]A new species of lionfish (Scorpaenidae: Pteroinae), Pterois paucispinula sp. nov., is described on the basis of 37 specimens from the western Pacific Ocean. The new species is closely related to and has been previously confused with Pterois mombasae (Smith 1957), both species sharing usually XIII, 10 dorsal-fin rays, usually more than 18 pectoral-fin rays, numerous black blotches on the pectoral-fin membrane, and several bands on the posterior portion of the pectoral-fin rays (free from membrane). However, P. paucispinula differs from similarly sized P. mombasae in having a lesser body depth at the anal-fin origin, head width, postorbital length, and caudalpeduncle depth, in addition to a slightly higher number of scale rows below the lateral line. Pterois paucispinula also differs from the typical form of P. mombasae, occurring off the east coast of Africa and in the central Indian Ocean and Andaman Sea, by having usually 18 pectoral-fin rays (vs. usually 19 in the latter) and relatively long dorsal-fin spines, with the longest dorsal-fin spine length 42.9–51.7 % of standard length (SL) (vs. 35.1–44.8 % of SL). Although a Sri Lankan population of P. mombasae is similar to P. paucispinula in the above characters (usually 18 pectoral-fin rays and longest dorsal-fin spine length 37.5–51.1 % of SL), such differences among P. mombasae are regarded as intra-specific geographical variations. Additionally, young and adult P. mombasae have ctenoid scales on the pectoral-fin base, ventrolateral portion of the body (below the lateral line) and laterally on the caudal peduncle. These regions in all examined P. paucispinula usually have only cycloid or at most a few ctenoid scales, thereby providing a consistent basis for identification of both species, including the Sri Lankan population of P. mombasae. Pterois mombasae is distributed in the Indian Ocean from the east coast of Africa to the Andaman Sea, whereas P. paucispinula is recorded from the western Pacific Ocean, from northern Australia to southern Japan and eastward to the Wallis and Futuna Islands.

Résumé [+] [-]A new species of scorpaenid fish, Ebosia vespertina sp. nov., is described on the basis of 19 specimens from off Mozambique, South Africa, and Madagascar, southwestern Indian Ocean. The new species is most similar to Ebosia falcata and Ebosia saya, known from the northern and eastern Indian Ocean and Saya de Malha Bank, respectively, in having usually 8 anal-fin soft rays, usually more than 17 pectoral-fin rays, and the elongated parietal spine in males narrow and strongly curved posterodorsally. However, E. vespertina can be distinguished from the two latter species by the following combination of characters: pectoral-fin rays 17–18 (modally 18); scale rows above the lateral line 4–6 (5); scale rows between the last dorsal-fin spine base and lateral line 4–5 (5); scale rows between the sixth dorsal-fin spine base and lateral line 4–5 (5); postorbital length 17.4–20.3 (mean 18.7) % of standard length (SL); longest pectoral-fin ray length 54.6–73.9 (65.1) % of SL; longest pelvic-fin soft ray length 32.4–44.0 (37.6) % of SL. The remaining congener, Ebosia bleekeri, known from the western Pacific Ocean, usually has 7 analfin soft rays and 16 pectoral-fin rays, and the elongated parietal spine in males relatively broad and not so strongly curved.

Résumé [+] [-]A taxonomic review of Plectrogenium (Teleostei: Plectrogeniidae) disclosed 10 valid species, eight being new (most previously identified as P. nanum Gilbert 1905): P. nanum (Hawaiian Islands); P. barsukovi Mandrytsa 1992 [Nazca Ridge (southeastern Pacific Ocean)]; P. capricornis sp. nov. (New Caledonia); P. kamoharai sp. nov. (Japan and Taiwan); P. kanayamai sp. nov. [Emperor Seamount Chain, Kyushu-Palau Ridge (northwest Pacific), and Taiwan]; P. longipinnis sp. nov. (Marquesas Islands); P. megalops sp. nov. (Solomon Islands); P. occidentalis sp. nov. (Madagascar); P. rubricauda sp. nov. (Japan); and P. serratum sp. nov. (Vanuatu). Each species can be distinguished from the others by a combination of morphological characters, including number of pectoral-fin rays, head spine and squamation characteristics, body proportions, and coloration. Plectrogenium nanum and P. barsukovi are briefly redescribed on the basis of their primary types. A key to the species of Plectrogenium is provided.

Résumé [+] [-]Dampierosa daruma Whitley 1932 and Erosa erosa (Cuvier in Cuvier and Valenciennes 1829) (Synanceiidae) were redescribed on the basis of both primary type and non-type specimens. The validity of Dampierosa Whitley 1932 has previously been uncertain, the name sometimes being regarded as a junior synonym of Erosa Swainson 1839. However, the following morphological differences between the type species of both genera (monotypic) confirmed the validity of the former: (1) usually XIII, 8 dorsal-fin rays in D. daruma (vs. XIV, 6 in E. erosa); (2) usually I, 6 anal-fin rays (vs. III, 5); (3) 12 pectoralfin rays (vs. 15); (4) dorsal head contour rounded in lateral view (vs. not rounded); (5) occipital pit star or asterisk shaped (vs. parallelogram or quadrate shaped); (6) opercle relatively small, with weakly developed spines and ridges (vs. opercle relatively large, with well developed spines and ridges); (7) 2nd mandibular pores (just behind mandibular symphysis) separated in large adults (fused, forming a single pore in small specimens) (vs. fused, forming a single pore throughout life); and (8) body entirely covered with numerous warts (vs. partially covered with warts). Erosa fratrum Ogilby 1910a and Erosa iridea Ogilby 1910b are regarded as junior synonyms of nominal Synanceia erosa. Dampierosa daruma is restricted to northwestern Australia, whereas E. erosa is widely distributed in the western Pacific and southeastern Indian Ocean, ranging from Australia, New Caledonia and Tonga north to Japan.

Résumé [+] [-]When the first Indo-Pacific Fish Conference (IPFC1) was held in Sydney in 1981, there were still many problems in the generic- and species-level taxonomy of all tetraodontiform families except for the recently reviewed Triacanthodidae and Triacanthidae. The period from IPFC1 to IPFC9 (1981-2013) was a time of great progress in the taxonomy and systematics of the Tetraodontiformes: many review and revisional papers have been published for various genera and species, with descriptions of many new taxa occurring mainly on coral reefs and in tropical freshwaters; and cladistic analyses of morphological characters have been performed to clarify phylogenetic relationships of various families and molecular analyses have greatly progressed to provide detailed phylogenetic relationships of families, genera, and even species. The purpose of this paper is to provide a review on developments in the taxonomy and systematics of the Tetraodontiformes, focusing primarily on contributions since 1980 (when James C. Tyler’s monumental work was published) through the period of IPFCs, including pertinent publications before 1980. This paper recognizes 412 extant species in the 10 families of living Tetraodontiformes, with the allocation of species and genera as follows: Triacanthodidae including 23 species in 11 genera, Triacanthidae seven species in four genera, Balistidae 37 species in 12 genera, Monacanthidae 102 species in 27 genera, Aracanidae 13 species in six genera, Ostraciidae 22 species in five genera, Triodontidae monotypic, Tetraodontidae 184 species in 27 genera, Diodontidae 18 species in seven genera, and Molidae five species in three genera. Phylogenetic relationships of the families have been clarified by morphological and molecular analyses and have provided well-supported sister relationships of the families: Triacanthodidae and Triacanthidae, Balistidae and Monacanthidae, and Tetraodontidae and Diodontidae. However, there remain problems with the phylogenetic positions of the Triodontidae and Molidae due to conflicts of differing positions in morphological and molecular studies (e.g., Molidae has been placed differently among molecular studies).

Résumé [+] [-]This paper reports upon the snake eels collected by trawl during the 1985 MUSORSTOM 4 New Caledonia Expedition. The 14 specimens comprised five new ophichthid taxa which are described herein: Ophichthus exounis sp. nov. from 400-520 m (also from Fiji); O. genie sp. nov. from 430-500 m (also from Maldives); O. mystacinus sp. nov. from 450-580 m; Yirrkala insolitus sp. nov. from 59 m; and Rhinophichthus penicillatus gen. et sp. nov. from 435 m. The dorsal fin location of the new species of Yirrkala provides an expanded character state within the genus. Rhinophichthus differs from other generalized ophichthins in its very conical snout, and includes Ophichthys unicolor Regan from South Africa. The affinities of the new taxa are with Indo-west Pacific ophichthids, however the collections are too few to allow significant conclusions about the bathyal ophichthid fauna of the region.

Zootaxa 3856(1): 117-134. DOI:10.11646/zootaxa.3856.1.5
Résumé [+] [-]Two new species of Hymenocephalus are described from the New Zealand region and Tasman Sea. Hymenocephalus fuscus sp. n. has 11–12 pelvic fin rays, is darkly pigmented, with enlarged bony ridges on the dorsal aspects of head, lacks a chin barbel, has few (16–19) gill rakers on inner side of first arch and is similar to other species in the H. aterrimus species group. Hymenocephalus maculicaudus sp. n. has 8 pelvic fin rays, a mid-lateral line of melanophores on body and tail that extends about a head length posterior to anal fin origin, a short (7–16 % HL) chin barbel and is similar to other species in the H. megalops species group. Hymenocephalus nascens has 12–14 pelvic fin rays, lacks a chin barbel, has a mid-lateral stripe of silvery (fresh) or brownish (preserved) pigment running along trunk and tail. Hymenogadus gracilis has a serrated (weak, near tip) first dorsal fin spine, 7–9 pelvic fin rays, long (20–30% HL) chin barbel, and one row of enlarged melanophores along lateral mid-line of the tail. Hymenocephalus nascens and Hymenogadus gracilis are recorded for the first time from the New Zealand region. A key to the known New Zealand species of Hymenocephalus and Hymenogadus is provided.

Taxonomy and distribution with ecological notes, in Crosnier A.(Ed.), Résultats des campagnes MUSORSTOM 21. Mémoires du Muséum national d'Histoire naturelle 184:723-781, ISBN:2-85653-526-7
Résumé [+] [-]We reported in an earlier paper the great species richness of the grenadier fauna (families Bathygadidae and Macrouridae) from recent bathyal trawl collections made mainly during MUSORSTOM cruises in the New Caledonian region. Here we add information from further samples to complement earlier taxonomic findings, and descriptions of 2 new species, together with comments on species, distribution and ecology. Thus a total of 2055 specimens from 221 samples examined representing 20 genera and 63 species were found to have closest similarity in composition with New South Wales, Western Australia and New Zealand. As expected, dissimilarity increased with distance from New Caledonia. Four genera dominated in species richness: Caelorinchus (17), Hymenocephalus (8), Nezumia (5) and Ventrifossa (6), comprising 2/3 of the total fauna. The generic make-up of the faunas closest to New Caledonia were most consistent with that region; propordons varied radically from there in the more distant regions invesdgated. Bathymetrically, the smaller trawls of the MUSORSTOM surveys collected grenadiers over a range of tows shallower than that reflected by the commercial gear used on the HALIPRO 2 cruise, with a generally smaller size of fish sampled. Co-occurrence of grenadier species within similar depth strata on the slope was remarkably high, with only two of the 63 species not represented, at least over part of their depth range, in the upper 1600 m. Species richness peaked at 37 in both the 700 and 800 tn strata, although it did not drop below 20 across the depth range 400-1100 m and reduced substantially only deeper than 1400 m.

Mémoires du Muséum national d'Histoire naturelle 191:611-635, ISBN:2-85653-557-7
Résumé [+] [-]Five species of the samarid genera Plagiopsetta and Samaris: P. stigmosa n. sp., P. gracilis n. sp., S. cristatus Gray, 1831, S. spinea n. sp. and S. chesterfieldensis n. sp., collected from New Caledonia and adjacent waters are described and keys to the species provided. Plagiopsetta stigmosa is easily separable from its congeners by having lateral lines on both sides and the pectoral fin with a jet-black blotch. Plagiopsetta gracilis is characterized by a uniformly dark pectoral fin, shallow body and caudal peduncle, a short ocular side pelvic fin, and large numbers of dorsal fin rays, anal fin rays, scales in the lateral line and vertebrae. Samaris spinea and S. chesterfieldensis are both characterized by caudal peduncle spines and bifurcated middle caudal fin rays, and are also separable by body depth.

Résumé [+] [-]Recent examinations of newly obtained materials of dracunculoid nematodes (Dracunculoidea) parasitizing marine fishes off New Caledonia, South Pacific, revealed the presence of several nematodes of the genera Philometra Costa, 1845 (Philometridae) and Ichthyofilaria Yamaguti, 1935 (Guyanemidae), including the following four new species: Philometra priacanthi sp. n. (males) from the gonads of Priacanthus hamrur (Forsskal) (Priacanthidae), Philometra tenuicauda sp. n. (male and mature and gravid females) from the gonads of Lagocephalus sceleratus (Gmelin) (Tetraodontidae), Philometra dentigubernaculata sp. n. (males) from the oculo-orbit of Tylosurus crocodilus (Peron et Lesueur) (Belonidae), and Ichthyofilaria novaecaledoniensis sp. n. (subgravid female) from the musculature of Hoplichthys citrinus Gilbert (Hoplichthyidae). The new species are characterized mainly by the length and structure of spicules and the gubernaculum, body size, location in the host and by the type of hosts. In addition, the findings of Philometra lethrini Moravec et Justine, 2008 from the gonads of Lethrinus miniatus (Forster) and L. variegatus Valenciennes (both Lethrinidae) represent new host records for this parasite; for the first time, its subgravid females were found to be up to 350 mm long. The occurrence of Philometra ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002 in the oculo-orbit of Epinephelus areolatus (Forsskal) (Serranidae) off New Caledonia was confirmed.

Résumé [+] [-]Recent examinations of spirurid nematodes (Spirurida) from deep-sea or coral reef marine fishes off New Caledonia, collected in the years 2006–2009, revealed the presence of the following five species: Ichthyofilaroides novaecaledoniensis (Moravec et Justine, 2009) n. gen., n. comb. (transferred from Ichthyofilaria Yamaguti, 1935) (females) (Guyanemidae) from the deep-sea fish Hoplichthys citrinus (Hoplichthyidae, Scorpaeniformes), Philometra sp. (male fourth-stage larva and mature female) (Philometridae) from Epinephelus maculatus (Serranidae, Perciformes), Ascarophis (Dentiascarophis) adioryx Machida, 1981 (female) (Cystidicolidae) from Sargocentron spiniferum (Holocentridae, Beryciformes), Ascarophis (Ascarophis) nasonis Machida, 1981 (males and females) from Naso lituratus and N. unicornis (Acanthuridae, Perciformes), and Ascarophisnema tridentatum Moravec et Justine, 2010 (female) from Gymnocranius grandoculis (Lethrinidae, Perciformes). Two species, I. novaecaledoniensis and A. nasonis, are redescribed based on light microscopical (LM) and scanning electron microscopical (SEM) examinations, the latter used in these species for the first time. Morphological data on the specimen of A. tridentatum from the new host species are provided. Philometra sp. (from E. maculatus) most probably represents a new gonad-infecting species of this genus. The newly established genus Ichthyofilaroides n. gen. is characterized mainly by the presence of a small buccal capsule and by the number and distribution of cephalic papillae in the female; it is the sixth genus in the Guyanemidae.

Zootaxa 4021(4): 529. DOI:10.11646/zootaxa.4021.4.3
Résumé [+] [-]The Indo-West Pacific species, Neomerinthe erostris (Alcock 1896), originally described as Scorpaena erostris, is redescribed as a senior synonym of Scorpaena gibbifrons Fowler 1938, N. rotunda Chen 1981, and N. bathyperimensis Zajonz & Klausewitz 2002. Although the latter three nominal species have been regarded as valid species and N. erostris has not been reported since 1898, examinations of type specimens of the four nominal species revealed that they represent a single species. A lectotype of Scorpaena erostris is herein designated. Neomerinthe erostris is characterized by having a distinct longitudinal ridge on the lateral surface of the maxilla and a strongly rounded dorsal profile of the head.

Résumé [+] [-]A taxonomic review of the scorpaenid genus Pteroidichthys Bleeker, 1856 resulted in recognizing four valid species, including two new species; P. acutus n. sp., P. amboinensis Bleeker 1856, P. caussei n. sp., and P. noronhai (Fowler 1938). The genus Pteropelor Fowler, 1938 is regarded as a junior synonym of Pteroidichthys. Rhinopias godfreyi Whitley 1954, previously treated as a valid species, is herein regarded as a junior synonym of P. amboinensis. Pteroidichthys amboinensis and P. caussei have two spines and six soft rays in the anal fin and a supplemental preopercular spine, whereas P. acutus and P. noronhai have three spines and five rays, and lack the spine. Pteroidichthys amboinensis differs from P. caussei in having flexible dorsal-fin spines (vs. rigid in the latter) and tentacles on the supraocular and posterior lacrimal spines well developed, their lengths greater than the orbit diameter (vs. less than orbit diameter). Pteroidichthys noronhai differs from P. acutus in having a relatively short snout, its length shorter than (vs. longer than in the latter) the postorbital length, and a distance between tips of the lateral lacrimal and first suborbital spines shorter than or subequal to (vs. longer than) that between tips of the first and second suborbital spines. Pteroidichthys acutus is known from the western Pacific in depths of 73–400 m, P. amboinensis from the Indo-West Pacific in 7–43 m, P. caussei from the South Pacific in 68–122 m, and P. noronhai from the western Pacific and Western Australia in 52–215 m.

Résumé [+] [-]Proctophantastes brayi n. sp. (Digenea: Zoogonidae; Lepidophyllinae) has been found in the intestine of two species of deep-sea fish Polymixia (silver eye fish) near the island of Erromango in Vanuatu at a depth ranging from 720 to 830 in. Specimen whole mounts, histological and scanning electron microscopy preparations showed that P. brayi differs from the five known species of the genus Proctophantastes (P. abyssorum, R gillissi, R glandulosum, P. infundibulum and P nettastomatis) by the following morphological characters: (i) a slit in the anterior part of the oral sucker, (ii) Laurer's canal is absent, (iii) a more extended periatrial gland than the ones in the other species of Proctophantastes, consisting of divided masses of cells and that form a conspicuous multilobated structure which does not have a membrane-bounded sac, (iv) the distal part of the metraterm has vesicle-like processes which we refer to as metratermal sacs, in addition to atrial sacs, (v) a long extension of the glandular cells surrounding the saccular bladder which extends posteriorly to the excretory pore.

Parasitology Research 110(5): 1631-1638. DOI:10.1007/s00436-011-2674-z
Résumé [+] [-]The present paper deals with Proctophantastes nettastomatis (Digenea: Zoogonidae; Lepidophyllinae) found in the intestine of three species of deep-sea fish, Dicrolene longimana (Ophidiidae, Ophidiiformes), Bathyuroconger sp. (Congridae, Anguilliformes), and Venefica tentaculata (Nettastomatidae, Anguilliformes). The fish were collected near the islands of Espiritu Santo, Erromango, and Epi, respectively, in the archipelago of Vanuatu (Southern Pacific Ocean) at depths ranging from 561 to 990 m. Morphological and histological analyses showed that the Vanuatu specimens differ from Proctophantastes abyssorum, Proctophantastes gillissi, Proctophantastes glandulosum, Proctophantastes infundibulum, and Proctophantastes brayi but are close to P. nettastomatis discovered in Suruga Bay, Japan. P.nettastomatis is redescribed based both on the observations of our specimens and of the Japanese holotype and paratype. The morphological variability of the species is described. Morphometric data allowed the identification of positive allometric growth for the hindbody, negative allometric growth for the ventral sucker, and a growth phenotypic plasticity between Ophidiiformes and Anguilliformes definitive hosts.

Résumé [+] [-]Pentanchus profundicolus is an enigmatic shark, characterized by a single dorsal fin. The holotype, which was collected in 1909 from the Philippines, had remained the only known example of the species for 90 years. A second specimen, collected from the same waters, is re-described. The presence of a single dorsal fin remains equivocal in so far as it represents the normal condition for the species. Aspects of the species' relationship with the species ofApristurus are discussed.

Nielsen J.G. & Uiblein F. 2014. The West Pacific Neobythites bimarginatus (Ophidiidae) recorded from off Madagascar. Cybium 38(4): 309–310
Résumé [+] [-]Neobythites is the largest known ophidiid genus with 52 valid species. It is commonly found on the lower part of the Continental Shelf and the upper part of the Continental Slope in the subtropical and tropical areas of all oceans, except for the East Atlantic Ocean. In 2010 a Neobythites specimen was caught off Madagascar. Twelve Neobythites species are known from the westernmost Indian Ocean (Nielsen, 1995), but the present specimen differs from them all, e.g., by the coloration of the dorsal and anal fins. Following the revision of the Indo-Pacific Neobythites species (Nielsen, 2002) it keys clearly out as N. bimarginatus Fourmanoir & Rivaton, 1979, known from New Caledonia and a few neighbouring islands.

Nielsen J.G. 2015. Revision of the aphyonid genus Aphyonus (Teleostei, Ophidiiformes) with a new genus and two new species. Zootaxa 4039(2): 323-344. DOI:10.11646/zootaxa.4039.2.7
Résumé [+] [-]The cosmopolitan, deep sea, aphyonid genus Aphyonus is known from less than 100 specimens. The type species A. gelatinosus Günther, 1878 and three additional valid species, A. brevidorsalis Nielsen, 1969, A. bolini Nielsen, 1974, and A. rassi Nielsen, 1975 were all based on single specimens. Since then several specimens have been caught of which 52 are examined for the present revision. Most of the specimens are referred to A. gelatinosus but also to A. bolini and A. rassi. A result of the enlarged material is that the type species, A. gelatinosus, is found to differ so much from the remaining species that a new genus, Paraphyonus, is established for these species. Furthermore two new species of Paraphyonus are here described, P. iselini based on six specimens from the tropical northwestern Atlantic Ocean and P. merretti based on three specimens from the northeastern Atlantic Ocean. The present knowledge of the variation of the Paraphyonus species makes it relevant to transfer Barathronus solomonensis Nielsen & Møller, 2008 to this genus.

Résumé [+] [-]A new epigonid fish, Epigonus draco n. sp., is described on the basis of six specimens (88.8–160.1 mm in standard length: SL) collected from the Philippines, Solomon Islands, and Vanuatu in the Western Pacific. This species belongs to a subgroup of Epigonus, known as the “Epigonus constanciae group,” whose members have a pungent opercular spine, more than 40 pored lateral-line scales (47–49 to the end of the hypural+3–4 on the caudal fin), and VII-I, 10 dorsal-fin rays. The new species is distinguished from other congeners of the group in having the following combination of characters: absence of a maxillary mustache-like process, absence of ribs on the last abdominal vertebra, total gill rakers 22–23; pyloric caeca 7–9; pectoral-fin rays 19–20; scales below lateral line 9; vertebrae 10+15; uppermost margin of pectoral-fin base lower than horizontal line through center of eye; proximal radial of first anal-fin pterygiophore slender; and mouth cavity black. In addition, Epigonus chilensis Okamoto, 2012 is rediagnosed based on specimens from near its type locality.

Résumé [+] [-]Epigonus okamotoi Fricke, 2017 was originally described on the basis of a single specimen collected from New Britain, Papua New Guinea during one of the exploratory cruises (campaign: MADEEP) in 2014 organized under the Tropical Deep-Sea Benthos program. However, there are no clear differences in the meristic and morphometric characters between the holotype of the new species and specimens of E. draco Okamoto, 2015, including two additional specimens of the species found in the ichthyological collections in the NTUM. The genetic distance (p-distance) between the two “species” at the COI locus was negligible. Accordingly, the holotype of E. okamotoi is considered to be a specimen of E. draco, and the former nominal species is reduced to a junior synonym of E. draco. In addition, we rediagnose and report new distributional records for E. atherinoides (Gilbert, 1905) and E. lifouensis Okamoto & Motomura, 2013 in the West Pacific.

Résumé [+] [-]A new ophidiid species, Neobythites machidai, is based on 7 specimens (63.0–93.5 mm SL), collected from Tosa Bay (139–176 m depth), Kochi Prefecture, southern Japan. It is most similar to N. bimarginatus, known from off New Caledonia, by having many pectoral-fin rays (>30), preopercle without spines and black bands in middle part of dorsal and anal fins. However, N. machidai differs from N. bimarginatus by pelvic-fin length 8.5–11.5% SL (vs. 11.5–13.5% SL in the latter species), longest gill filament 6.9–10.0% HL (vs. 4.8–6.3% HL), each side of triangular vomerine tooth patch concave (vs. Slightly convex), snout shorter than horizontal eye window (vs. Snout longer than eye), and 11–13 (vs. 6–7) light spots on middle part of body. Additionally, they differ in many characters such as number of dorsal-fin rays, pectoral-fin rays and total vertebrae and preanal length.

Peristiwady T. 2012. Historical review of ichthyological research in Indonesia. Coastal Marine Science 35(1): 153-156
Résumé [+] [-]The history of ichthyological research in Indonesian waters falls into four major periods: pre-colonial recorded history until the end of the 16th century), colonial (from the beginning of the 17th century to Indonesian independence in 1945), post-independence (from 1945 to 2000) and the 21st century. Scientific fish collections began with French expeditions conducted in the early 19th century, including La Physicienne (1817-1820), l'Uranie (1818-1819), La Coquille (1823), L'Astrolabe (1826-1829) and La Bonite (1836-1837). Bristish and Dutch expeditions included those of H. M. S. Curacoa (1873) and HMS Challenger (1872-1876), the Siboga (1899-1900), and the Snellius I (1929-1930) respectively. These expeditions did not involve Indonesian scientist; nor were collected materials deposited in Indonesian Institutions. More recent expeditions and with the participation of the Indonesian Governement included the Baruna Expedition (1964), the Te Vega (1963, 1965) and the Alpha Helix Cruises (1979), The Rumphius Expedition I-IV ( 1972-1980), The Corindon Expedition II-III (1982-1984), the Snellius II (1984-1985), the Karubar (1991) and the Anambas (2002).

No longer a circumtropical species: revision of the lizardfishes in theTrachinocephalus myops species complex, with description of a new species from the Marquesas Islands: taxonomic revision of trachinocephalus. Journal of Fish Biology 89(2): 1302-1323. DOI:10.1111/jfb.13038
Résumé [+] [-]Trachinocephalus, a formerly monotypic and nearly circumtropical genus of lizardfishes, is split into three valid species. Trachinocephalus gauguini n. sp. is described from the Marquesas Islands and is distinguished from the two other species in the genus by having a shorter snout, a narrower interorbital space, larger eye andmodally fewer anal-fin and pectoral-fin rays. The distribution of Trachinocephalus myops (type species) is restricted to theAtlantic Ocean and the name Trachinocephalus trachinus is resurrected for populations from the Indo-West Pacific Ocean. Principal component analyses and bivariate plots based on the morphometric data differentiated T. gauguini from the other two species, but a substantial overlap between T. myops and T. trachinus exists. Phylogenetic evidence based on mtDNA COI sequences unambiguously supports the recognition of at least three species in Trachinocephalus, revealing deep divergences between the Atlantic Ocean, Indo-West Pacific Ocean andMarquesas entities. Additional analyses of species delimitations using the generalized mixed Yule coalescent model and the Poisson tree processesmodel provide amore liberal assessment of species in Trachinocephalus, indicating that many more cryptic species may exist. Finally, a taxonomic key to identify the three species recognized here is provided.

Résumé [+] [-]Two new species of the mesopelagic genus Photonectes are described from the Pacific Ocean. Both of them are characterized by the presence of blue luminous tissue on the body. Photonectes cyanogrammicus new species, is characterized by the unique shape of the mental barbel, expanded distally and lacking bulbs or appendages. It is presently known only from the holotype collected in the Solomon Sea. Photonectes sphaerolampas new species, is described from four specimens collected in the western and central Pacific. It can be easily distinguished from the other species by the presence of the large spherical bulb of the mental barbel with darkly pigmented terminal appendage, split at its tip into several short filaments. Photonectes mirabilis Parr, 1927 is re-described, based on four specimens from the Atlantic and Pacific Oceans; details of jaw dentition and arrangement of the luminous tissue for this species are specified. A key for identification of the species of Photonectes with blue luminous tissue on the body is provided.

Résumé [+] [-]Identification of taxonomical units underpins most biological endeavours ranging from accurate biodiversity estimates to the effective management of sustainably harvested, protected or endangered species. Successful species identification is now frequently based on a combination of approaches including morphometrics and DNA markers. Sequencing of the mitochondrial COI gene is an established methodology with an international campaign directed at barcoding all fishes. We employed COI sequencing alongside traditional taxonomic identification methods and uncovered instances of deep intraspecific genetic divergences among flathead species. Sixty-five operational taxonomic units (OTUs) were observed across the Indo-West Pacific from just 48 currently recognized species. The most comprehensively sampled taxon, Platycephalus indicus, exhibited the highest levels of genetic diversity with eight lineages separated by up to 16.37% genetic distance. Our results clearly indicate a thorough reappraisal of the current taxonomy of P. indicus (and its three junior synonyms) is warranted in conjunction with detailed taxonomic work on the other additional Platycephalidae OTUs detected by DNA barcoding.

Résumé [+] [-]Five new species of the damselfish genus Chromis (Perciformes: Labroidei: Pomacentridae) are described from specimens collected from deep (>60 m) coral-reef habitat in the western Pacific by divers using mixed-gas closed-circuit rebreather gear. Two of the five new species (C. abyssus and C. circumaurea) are each described from specimens taken at a single locality within the Caroline Islands (Palau and Yap, respectively); one (C. degruyi) is described from specimens collected or observed throughout the Caroline Islands, and two (C. brevirostris and C. earina) are described from specimens collected from several localities throughout the Caroline Islands, Fiji, and Vanuatu. All five species can easily be distinguished from other known Chromis, and from each other, on the basis of color and morphology. These new species represent the first five scientific names prospectively registered in the official ICZN ZooBank registry. Moreover, the electronic online edition of this document has been specially formatted with many embedded links to additional resources available online via the internet to enhance access to taxonomically-relevant information, and as a demonstration of the utility of international standards for biodiversity informatics.

Résumé [+] [-]The CHALCAL I cruise on board of the RV Coriolisi the Chesterfield Island region (19°-22°S and 157°-160°E) has allowed the collection of many fish species. We present here two detailed lists of these fishes. The first list includes 75 lagoonal species, caught between 60 and 90 m, 26 species of which are mentioned for the first time in this region. The second list includes 73 species of the bathyal zone (200-400) 35 of which are also new to this region. Biogeographical remarks allow to show affinities between the fish populations of this archipelago and those from nearby zones such as New Caledonia and Australia, but also those from tropical Japan.

Résumé [+] [-]The present checklist is a compilation of aIl fish species known from the 200 miles limit around New Caledonia. A total of 1759 species are distributed among 199 families. The most speciose families are shallow water and benthic, if one excepts the Myctophidae which are pelagic. Two tables allow a few comparisons with other checklists from the Pacific. However one should be cautious when making such comparisons because the sampling effort may be very different from one checklist to the next. In new Caledonia most of the sampling has taken place in the South West lagoon and on the soft bottoms of the North. More sampling is needed in particular on the outer reef slopes of the barrier reef, on the sea mounts, around the atolls of Uvea, Surprises t Beautemps-Beaupré, the Loyalty islands and the isle of Pines. This checklist will he completed later with a list of the most common synonyms, vernacular names for most species and a better bibliography

Résumé [+] [-]The Australasian sandfish, Gonorynchus forsteri Ogilby, is recorded for lhe first time from the New Caledonian Exclusive Economic Zone (EEZ). The record is based on two adult specimens, one running ripe female and one spent or resting male, captured at 960-1233 m depth on the Loyalty Island Ridge and Lord Howe Rise. Their presence in bathyal depths over 700 nautical miles from the nearest known populations is discussed and compared with the occurrence of the species in New Zealand waters.

Résumé [+] [-]A pelagic record of a rare deep-water shark, the velvet dogfish Zameus squamulosus (Günther, 1877), is described from the southwestern Indian Ocean. This is the first pelagic record from the western Indian Ocean and the eleventh published record of this species from the entire basin. Together with non-published records from museums and online databases the number of verified Indian Ocean records of this species currently exceeds 50 individuals. Zameus squamulosus is a benthopelagic species usually occurring on the slopes of the continents and in mid-ocean oceanic ridges, between 400 and 1450 m depth, but it makes rare incursions in open water to the limits of the epipelagic zone.

Santini F. 2006. A new species of Triacanthodidae (Tetraodontiformes, Acanthomorpha) from the central Pacific. Cybium 30(3): 195–198
Résumé [+] [-]A new species of Triacanthodidae (Tetraodontiformes, Acanthomorpha) from the central Pacific is described from 24 specimens. This species, Bathyphylax pruvosti, exhibits a much longer snout than other species of the genus Bathyphylax. Its collection in the Marquesas Islands, French Polynesia, extends the geographical range occupied by species of the triacanthodid subfamily Triacanthodinae, previously known only from the Indo-western Pacific and the Caribbean (one species).

Sasaki D. & Kimura S. 2014. Taxonomic review of the genus Hypoatherina Schultz 1948 (Atheriniformes: Atherinidae). Ichthyological Research 61(3): 207-241. DOI:10.1007/s10228-014-0391-1
Résumé [+] [-]The marine atherinid fishes of the genus Hypoatherina Schultz 1948 (Atherinidae: Atherinomorinae) were redefined from both morphological and molecular analyses, and eight of the ten included species were redescribed. In the molecular phylogeny, four regions of mitochondrial DNA were analyzed. The results of both trees of maximum likelihood and Bayesian analyses indicated the paraphyly of the former Hypoatherina. ‘‘Atherina’’ valenciennei and ‘‘Atherina’’ woodwardi, both formerly belonging to Hypoatherina, show closer relationships with Atherinomorus duodecimalis and Atherinomorus aetholepis. ‘‘Hypoatherina’’ celebesensis is also apart from the clade including the majority of Hypoatherina species. In contrast, H. panatela, formerly regarded as a member of the genus Stenatherina Schultz 1948, is included in the present Hypoatherina clade. The present molecular phylogeny of the genus Hypoatherina can be supported by morphology. The genus Hypoatherina is redefined by the following combinations of characters: ascending process of premaxilla long and slender, its height more than 2.7 times the maximum width; both anterior and posterior lateral processes of premaxilla narrow and deep, the anterior process almost the same as or slightly deeper than the posterior process; premaxilla not tapering posteriorly; posterior upper margin of dentary with a prominent process; upper posterior limb of dentary with round or somewhat angular posteroventral corner; anterior preopercular ridge with a deep notch just above the corner; anus situated posterior to or slightly anterior to appressed pelvic-fin tip in adults; dorsoventral height of exposed area in the midlateral scale (third) row wide, almost equal to the maximum height of the scale, and almost the same height as scales just above or below the midlateral row. The redefined Hypoatherina includes the following ten species: H. barnesi—widely distributed in the Indo-Pacific; H. gobio (lectotype designated herein)—restricted to the Red Sea; H. golanii— restricted to the Gulf of Aqaba, inner Red Sea; H. klunzingeri— from Mozambique to eastern South Africa; H. lunata—distributed in Japan and Indonesia; H. panatela— from western and central Pacific Ocean; H. temminckii— widely distributed in the Indo-West Pacific (neotype designated herein); H. tropicalis—restricted to the northeastern coast of Australia; H. tsurugae—occurring in Japan and South Korea; and H. uisila—distributed in the western and central Pacific Ocean.

Sato T. & Nakabo T. 2002. Paraulopidae and Paraulopus, a new family and genus of aulopiform fishes with revised relationships within the order. Ichthyological Research 49(1): 25–46
Résumé [+] [-]A species group hitherto concealed within Chlorophthalmus (Chlorophthalmidae) is described as a new family and genus of Aulopiformes, Paraulopidae and Paraulopus, respectively. Paraulopus clearly belongs in Aulopiformes owing to an enlarged uncinate process on the second epibranchial, the absence of a swimbladder, and fusion of the medial processes of the pelvic girdle, but characterized by having the following combination of characters: the fourth basibranchial with a long tail but no gap separating fourth basibranchial and fifth ceratobranchial, epipleural bones distributed from posterior portion of abdominal vertebra to anterior portion of caudal vertebra, and flesh specimens of most species with paired olive spots dorsally on body. The phylogenetic position of Paraulopus is defined by a cladistic analysis of 101 morphological characters, in 21 genera of Aulopiformes. In a single most parsimonious tree, Paraulopus and Chlorophthalmus are in two different major clades, there being four major clades in all, roughly corresponding to the four suborders of Aulopiformes. Paraulopidae is included in the suborder Synodontoidei. In addition, Bathysauroides is transferred to Chlorophthalmoidei from Giganturoidei, and Bathysauroides and Bathysauropsis are elevated to familial status.

Résumé [+] [-]We recognize six species of Mataeocephalus : M. acipenserinus, M. adustus, M. cristatus sp. nov., M. tenuicauda, M. kotlyari sp. nov., and M. hyostomus. The last species was formely considered to belong to Hyomacrurus, a genus that was thought, based on its six branchiostegal rays, to be most closely related to Coryphaenoides, but differing in the advanced placement of the anus. We consider Hyomacrurus to be a synonym of Mataeocephalus, but retain it as a subgenus containing two species, M. kotlyari and M. hyostomus. Mataeocephalus microstomus Regan and M. nigrescens Smith and Radcliffe are relegated to the synonymy of M. acipenserinus. A revised diagnosis of Mataeocephalus is provided, and its status within the group of macrourids with seven branchiostegal ray is discussed.

Schwarzhans W.W. & Prokofiev A.M. 2017. Reappraisal of Synagrops Günther, 1887 with rehabilitation and revision of Parascombrops Alcock, 1889 including description of seven new species and two new genera (Perciformes: Acropomatidae). Zootaxa 4260(1): 1. DOI:10.11646/zootaxa.4260.1.1
Résumé [+] [-]An ongoing review of the fishes of the basal percoid family Acropomatidae has revealed that the genus Synagrops Günther, 1887 as it is currently understood is not a natural group. Species with a serrated pelvic-fin spine are here placed in the resurrected genus Parascombrops Alcock, 1889 (type-species: Parascombrops pellucidus Alcock, 1889), and the new, monospecific genus Caraibops n. gen. (type-species: Synagrops trispinosus Mochizuki & Sano, 1984). Parascombrops is unique amongst Acropomatidae in the combination of the presence of vacant 8th interneural space, a predorsal formula /0+0/0+2/ and an epaxialis attachment type 1. Caraibops n. gen. shares none of these characters and further differs from Parascombrops by an anal-fin formula of III + 9 (vs II + 7 or III + 6), and the absence of denticles on the ectopterygoid. Parascombrops is revised and now contains a total of 13 species, including 7 new: P. analis (Katayama, 1957), P. argyreus (Gilbert & Cramer, 1897), P. glossodon n. sp., P. madagascariensis n. sp., P. mochizukii n. sp., P. nakayamai n. sp., P. ohei n. sp., P. parvidens n. sp., P. pellucidus Alcock, 1889, P. philippinensis (Günther, 1880), P. serratospinosus (Smith & Radcliffe, 1912), P. spinosus (Schultz, 1940) and P. yamanouei n. sp. Synagrops adeni Kotthaus, 1970 and S. malayanus Weber, 1913 are treated as synonyms of P. pellucidus and P. philippinensis, respectively. Lectotypes are designated for P. philippinensis and S. malayanus. The main characters used to distinguish between the species of Parascombrops are: serration of other fin spines, number of gill rakers and pseudobranchial filaments, head profile, presence or absence of ridges on the preopercle, shape of 1st anal-fin pterygiophore, dentition on vomer, palatines and ectopterygoids, orbit diameter, pectoral-fin length, maximal body depth and otolith morphology. The genus Synagrops is here confined to two species, S. japonicus (Döderlein, 1883) and S. bellus (Goode & Bean, 1896), characterized by the apomorphic character of an otic capsule with a posteriorly open myodome, a basioccipital fossa and a very specialized otolith morphology. Synagrops is also characterized by the absence of pelvic-fin spine serrations. Two other species without a serrated pelvic-fin spine, originally described in Synagrops, are removed from this genus. Synagrops microlepis Norman, 1935 is separated into the monotypic Kaperangus n. gen., the only genus in the family with two supraneurals (cf. three in all other taxa). The second, Synagrops pseudomicrolepis Schultz, 1940 is re-assigned to the genus Verilus. The geographic distribution of Parascombrops as currently composed is discussed, and is shown to be primarily of West Pacific nature, with few species in the Indian Ocean and one in the tropical West-Atlantic (P. spinosus). The West Atlantic species Parascombrops spinosus is very closely related to P. mochizukii from the tropical northwestern Pacific, and the implications of this disjunct distribution are discussed. The high degree of speciation now recognized in Parascombrops species of the West-Pacific indicates that a diverse ecological adaptation within an overall pseudoceanic habitat may have played a major role in speciation, which would have remained obscured without adequate taxonomic resolution. Fossil, otolith-based records are also briefly discussed in the context. The extant Parascombrops argyreus and P. ohei are reported from the Pliocene of Japan, and Caraibops trispinosus has been recorded from the Pliocene of Venezuela.

Résumé [+] [-]A new genus and two new species of congrid eels, subfamily Bathymyrinae, are described from the western Indian Ocean and the western Pacific. Kenyaconger gen. nov. differs from all other congrids in having a tubular posterior nostril, opening on the edge of the upper lip behind the labial flange. Kenyaconger heemstrai sp. nov., the only species in the genus, is described from a single specimen collected off the coast of Kenya in the western Indian Ocean. Chiloconger philippinensis sp. nov. is described from the Philippines, the first record of the genus outside the eastern Pacific. It differs from Chiloconger dentatus (Garman, 1899) in several meristic and morphometric characters. Chiloconger dentatus is redescribed from additional material and its osteology is described for the first time. Chiloconger similis Wade, 1946 is reassigned to Paraconger Kanazawa.

Résumé [+] [-]A new species of congrid eel, Bathycongrus villosus sp. nov., is described from the Philippines and Vanuatu. It is similar to some of the small-toothed species currently placed in Bathycongrus and to the species of Bassanago. In this paper we compare the new species to Bassanago albescens (Barnard, 1923) and to Bathycongrus parviporus Karmovskaya, 2011, which it most closely resembles. An analysis of 19 characters shows that it agrees with Bat. parviporus in 16 characters and with Bas. albescens in one. In two characters, the three species are all different. We therefore place it in Bathycongrus.

Résumé [+] [-]The bandfish family Cepolidae, comprising the subfamilies Owstoniinae and Cepolinae, is characterized, and defining characters of the three groups are identified and discussed. Characters of larvae of both subfamilies are described and illustrated. Six nominal genera of owstoniines had been proposed by various authors, but we recognize only Owstonia Tanaka. Utility of selected identification characters of the genus are discussed. Differences in lateral-line patterns have been the primary character used by some recent authors for recognition of two owstoniine genera, with Sphenanthias Weber possessing the plesiomorphic lateral-line condition. Several other patterns also occur in these fishes bringing into question the phylogenetic significance of lateral line plasticity. Sexual dimorphism in pelvic fin lengths is also present in several species. Identification keys, descriptions, synonymies, distribution maps and photographs or illustrations are provided for all Owstonia species for which adults are available. Although only 15 valid species were previously known, a remarkable hidden diversity of these fishes was discovered in major museum collections with the following 21 species here described as new: O. ainonaka (eastern Australia), O. contodon (Philippines), O. crassa (New Caledonia and Solomon Islands), O. dispar (Solomon Islands), O. elongata (New Caledonia and Vanuatu), O. fallax (eastern Australia and New Caledonia), O. geminata (Vanuatu and Philippines), O. hastata (eastern Australia), O. hawaiiensis (Hawaiian Islands); O. ignota (Mariana Islands), O. lepiota (Tanzania), O. melanoptera (Philippines), O. merensis (eastern Australia, Torres Strait), O. mundyi (Kiribati, Christmas Island), O. nalani (eastern Australia and New Caledonia), O. nudibucca (eastern Indian Ocean, Mentawai Islands and off Myanmar), O. psilos (Western Australia), O. raredonae (Mozambique), O. rhamma (Vanuatu), O. scottensis (Western Australia, Scott Reefs) and O. similis (Madagascar). Several specimens based on small juveniles, which we describe as Owstonia sp., appear to be additional new species but are not formally described as such.

Résumé [+] [-]During the MUSORSTOM 4 (N.O. “Vauban”, September-October 1985), BIOCAL (N.O. “J. CHARCOT”, August 1985) and MUSORSTOM 5 (N.O. “Coriolis”, October 1986) oceanographic expeditions, numerous fragments and some teeth of Procarcharodon megalodon (Fig, 1) were dredged, sometimes trawled, north and south of New Caledonia and on the “Chesterfield Islands Plateau” at depths between 350 and 680 meters (Fig. 2 and Table I). At the same depths other shark teeth were collected (Carcharodon carcharias, Isurus cf. oxyrinchus, Galeocerdo cf. cuvieri) as well as abundant pharyngeal teeth of Labrodon sp. (Labridae) and Diodon sp. (Diodontidae), probably new species (Figs. 3 and 4). A similar association (teeth of P. megalodon and teeth of C. carcharias) has been recently observed by de Muizon and DeVries (1985) in the Pliocene sandstones of the Sacaco region (Peru). A sample of about thirty teeth of Procarcharodon megalodon has been retained and deposited in the collection of the Laboratoire de Paléontologie du Muséum National d’Histoire Naturelle de Paris (MNHN number 1986-3). The collecting sites are indicated in Figure 2 and their coordinates in Table 1 (re: the detailed report on the MUSORSTOM 4 expedition by Richer de Forges, 1986). The teeth are often broken and the cutting edges dulled. They constitute a large, thick, triangular crown, covered with enameloid, and a strong bilobate root. The crown exhibits a flattened or slightly concave labial side, smooth and yellowish-brown in color and a convex dark brown lingual side. The enameloid coating is thicker on the labial side than on the lingual one. On the lingual side, a chevron-shaped and non-enameloid-coated bourlette, separates the crown from the root. Vertical striations in the enameloid are observed on both sides. The convex side is generally more eroded and encrusted than the flat side, which suggests that the teeth sit on the bottom with their convex sides serving as a supporting structure for various sedentary organisms: sponges, bryozoans, corals, and tube worms. The largest collected tooth has a broken tip (Figure 6) but considering its width (106 mm), its total height must have been close to 135 mm. Although the tips and cutting edges are often broken off or dulled, some serrations are visible on the cutting edges of certain well-preserved teeth. The thickness of the largest tooth is 37 mm. The ocean floor, consisting of the external slopes of the fringing reef around New Caledonia, is generally hard and sandy. The teeth were collected with a Waren rock dredge: some specimens were trawled, notably one block containing several teeth jumbled together in a sandy matrix (site CP 193). The sedentary fauna on the teeth testify to a weak sedimentation rate. In fact in the prospected zones the slopes are steep, the currents turbulent, and the terrigenous deposits unsubstantial. The teeth found at site DW 36 (BIOCAL) are black. They were quite probably buried in the sediment and they are the teeth collected at the greatest depth (650-680 m) of the combined expeditions. P. megalodon was a cosmopolitan species for which Leriche (1936) provided a map of its geographic and stratographic distribution. The species appears in Miocene strata (around 25 million years ago) and disappears in the Pleistocene (one million years old or less according to estimates). The Pleistocene deposits are mostly offshore and have been exposed by the dredging of the Challenger and the Albatross off the coasts of the islands of Tubuai and Tahiti in the “polymetallic nodule” fields at depths over 4000 m. P. megalodon is the largest of all known sharks. Various estimates of its size have been made by extrapolation from the “tooth dimensions-animal body size” relationship established for the great white shark, Carcharodon carcharias. Therefore, Leriche (1926) recognizes that P. megalodon could attain a length of 40 m! This exorbitant figure results from the fact that the size of C. carcharias used as a reference was, itself, overestimated. Randall (1973) demonstrated that the great white shark certainly reaches 6.4m in length and at the most 8 m. One projection of his “enamel height-C. carcharias body size” relationship produces a size around 13m for the largest fossil shark.

Résumé [+] [-]Four new species of urolophid stingarees are described from the Coral Sea (South-West Pacific): Urolophus deforgesi sp. nov. and U. papilio sp. nov. from the continental slope of the Chesterfield Islands; U. neocaledoniensis sp. nov. is more widely distributed on the slopes of the Chesterfield Islands and New Caledonia and along the northern part of the Norfolk Ridge; U. piperatus sp. nov. is restricted to the coast of northern Queensland (Australia). The holotype and only known specimen of a rare and unusual stingaree, U. annatus Val. in Muller & Henle, 1841 from New Ireland (Bismark Archipelago), is redescribed and it could represent a new genus. The new species are mainly distinguished by a combination of the following characters: disc shape (particularly its width), dorsal fin (present or absent), interorbital distance (narrow or broad), tail length (short or elongated), coloration (plain or with spots), and oral papillae, vertebrae and pectoral-fin radial counts. A key for the urolophids of the Coral Sea is provided.

The body coloration, which is plain greyish brown with large dark blotches on dorsal and caudal fins and their bases, closely resembles its sibling G. gracilis, a northern Australian and Indonesian species. An identification key to Indo-Pacific Galeus species is provided.

Résumé [+] [-]Four new skates of the genus Notoraja Ishiyama, 1958 are described from the rarely accessed, deep waters off New Caledonia, Vanuatu and Fiji islands, and the Norfolk Ridge. Three of these (N. alisae n. sp., N. longiventralis n. sp. and N. fijiensis n. sp.) are “velcro skates” which are characterised by their velvety dorsal and ventral surfaces, covered with fine denticles. Although similar in shape, they differ by their colour pattern, dermal armature, development of the lateral tail folds, and size of the pelvic-fin anterior lobe and nasal curtain. The description of the fourth species, Notoraja inusitata n. sp., is based on a juvenile male exhibiting some unusual features resembling those of other skate genera.

Résumé [+] [-]The new synaphobranchid eel Ilyophis singularis is described on the basis of two specimens (248–270 mm in total length) collected from the northeastern South China Sea at a depth between 1,612 and 1,665 m. The new species is characterized by a low number of vertebrae, with 116–118 total vertebrae, which is the smallest known for a species in Ilyophis. In addition, it differs from its congeners by the following combined characteristics: preanal vertebrae 36–37; sensory pores in supraorbital series 3 (pores absent above eye); sensory pores in infraorbital series 7 or 8 (2 or 3 pores behind eye); sensory pores absent on frontal and supratemporal regions; and body naked.

Tomiyama S., Takami M. & Fukui A. 2016. Redescription of Bassozetus compressus (Günther 1878), a senior synonym of Bassozetus elongatus Smith and Radcliffe 1913 (Ophidiiformes: Ophidiidae). Ichthyological Research 63(2): 218-226. DOI:10.1007/s10228-015-0491-6
Résumé [+] [-]Re-examination of two deep-sea ophidiid species, Bassozetus compressus (Gu¨nther 1878) and Bassozetus elongatus Smith and Radcliffe in Radcliffe 1913, based on specimens from the West Pacific, Atlantic and Indian Oceans, disclosed no morphologically significant differences amongst those from the West Pacific, including the lectotype of B. compressus and holotype of B. elongatus. Two characters considered to distinguish between the species [pelvic-fin length to standard length (SL) ratio and position of a small process on the sagittal otolith] were found to be invalid, leading to the conclusion that B. compressus is a senior synonym of B. elongatus. The remaining specimens from the Atlantic and Indian Oceans, previously reported as B. compressus or B. elongatus, represented one or more as-yet undescribed species. A detailed redescription of B. compressus is provided on the basis of the West Pacific specimens, the species being distinguishable from all other congeners by the following combination of characters: dorsal-fin rays 118–127; pectoral-fin rays 22–26; oblique scales ca. 18–20; vertebrae 11–13 ? 54–58 = 66–69; distance between base of pelvic fin to origin of anal fin 15.8–20.5 % SL; eye diameter 2.0–2.7 times in snout length; a median basibranchial tooth patch; anterior margin of sagittal otolith with a small process, dorsal margin smooth. Two specimens of B. compressus, collected from off Uotsurijima Island, Senkaku Islands and Kumejima Island, Okinawa Islands, represent the first record of this species from Japanese waters.

Tongboonkua P., Lee M.Y. & Chen W.J. 2018. A new species of sinistral flatfish of the genus Chascanopsetta (Teleostei: Bothidae) from off Papua New Guinea, western Pacific Ocean. Zootaxa 4476(1): 168. DOI:10.11646/zootaxa.4476.1.16
Résumé [+] [-]Left-eyed flounders of the genus Chascanopsetta Alcock 1894 (Bothidae) occur in the Indian, Pacific, and Atlantic oceans at depths ranging from 120 to 1500 meters. They possess some unique features in bothid fishes including a strongly compressed and elongated body and a tremendously large mouth. Currently, nine species of Chascanopsetta are recognized, and three of them (C. micrognatha Amaoka & Yamamoto 1984, C. lugubris Alcock 1894 and C. prognatha Norman 1939) are distributed in the West Pacific. We collected 25 specimens of Chascanopsetta during 11 biodiversity expeditions carried out mainly in the West Pacific. Among them, eight specimens taken off Papua New Guinea present morphological features that differ from those of the three nominal species known in the West Pacific. In this study, we examined these eight specimens of unknown affinity and compared their morphology to that of specimens of other congeneric species. Results of these comparisons showed that these specimens represent an undescribed species of Chascanopsetta, named herein, C. novaeguineae sp. nov.. The new species resembles C. elski Foroshchuk 1991, which is known only from the Saya de Malha Bank in the western Indian Ocean, in having a high number of gill rakers (> 13). However, the combination of the following characters further distinguishes C. novaeguineae sp. nov. from C. elski: longer jaws, narrower interorbital width, and number of pseudobranches (21–25 vs. 26–27). The DNA sequences from the mitochondrial cytochrome oxidase subunit I (COI) gene from C. novaeguineae sp. nov. and other species were obtained and compared to confirm its taxonomic status and to infer its tentative phylogenetic position within the Chascanopsetta.

Uiblein F. & Mcgrouther M. 2012. A new deep-water goatfish of the genus Upeneus (Mullidae) from northern Australia and the Philippines, with a taxonomic account of U. subvittatus and remarks on U. mascareinsis. Zootaxa 3550: 61–70
Résumé [+] [-]Upeneus stenopsis n. sp. is described based on four specimens collected off northern Australia and Quezon Island, Philippines, at depths between 165 to 275 m and compared with four closely related species: the deep-water dwelling Upeneus davidaromi (Red Sea) and U. mascareinsis (Western Indian Ocean) and the shallow Indo-West Pacific species, U. subvittatus and U. vittatus. The new species can be distinguished from all other Upeneus species by a narrow caudal peduncle and a combination of morphometric and meristic characters. This is the first record of a deep-water goatfish of the genus Upeneus from the Pacific. A juvenile Upeneus collected off Quezon at 127–142 m depth was also assigned to the new species and compared to four similar-sized (69–79 mm SL) specimens of U. mascareinsis. A diagnosis is provided for U. subvittatus, along with evidence of its occurrence in the Eastern Indian Ocean and interspecific comparisons. The continued need to screen scientific fish collections for the occurrence of undescribed species that have successfully colonized and adapted to the depth zone surrounding the ocean margin is outlined.

Résumé [+] [-]A new goatfish, Upeneus vanuatu (Mullidae), is described based on five specimens collected off two islands of Vanuatu (South Pacific), at depths of 191–321 m, and compared with five closely related species: Upeneus davidaromi (Red Sea), U. mascareinsis (Western Indian Ocean), U. stenopsis (northern Australia, Philippines, 127–275 m), and the more shallow- occurring Indo-West Pacific species U. subvittatus (26–120 m) and U. vittatus (<100 m). The new species can be distinguished from all other congeneric species by the combination of four characters: number of gill rakers on lower limb, caudal-peduncle depth, interorbital length, and interdorsal distance. Strong allometric variation in body form between the holotype and the four smaller paratypes was found. Based on the lack of lateral body stripes, a rather narrow caudal peduncle depth, and large eyes in adults as common characteristics for U. subvittatus and the four deep-water Upeneus species, the so-called “stenopsis” species group can be distinguished from four other species groups that were established in earlier studies in order to facilitate intrageneric comparisons. The ecological and evolutionary significance of deep-water goatfishes is briefly discussed.

Résumé [+] [-]A new goatfish, Upeneus torres sp. nov. (Mullidae), is described based on 27 specimens from Australia and Vanuatu using a diversified alpha-taxonomy approach that integrates species, population and size-related allometric differences. Based on large sets of comparative morphological and colour data, diagnoses and inter- and intraspecific comparisons are provided for similar and/or co-occurring species of the so-called japonicus species group, Upeneus torres sp. nov., U. australiae, U. guttatus, and U. japonicus. The new species can be distinguished from all congeneric species by the following combination of characters: seven spines in the first dorsal fin; 13–15 (typically 14) pectoral-fin rays, 22–25 total gill rakers, barbel length 24–28 %SL, and pectoral-fin length 24–26 %SL. Fish smaller than 65 mm SL (‘subadults’) of the new species differ from larger conspecifics (‘adults’) in shallower body, larger eyes, longer anal-fin base, and longer caudal fin. Similar size-related differences were also found for the three other species. Phenotypic population differences in the new species as well as in U. guttatus are reported that may reflect character displacement in the latter. The need to study size–depth–habitat relationships in more detail, the phylogeography of individual populations, and the overall diversity of the genus Upeneus from Australian waters is discussed.

Résumé [+] [-]The phenotypic, distributional, and genetic distinctiveness of the bandtail goatfish Upeneus taeniopterus within the genus Upeneus (Mullidae) is elaborated using a comprehensive alpha-taxonomic and barcoding approach. Based on a large number of morphometric, meristic and colour characters obtained from 71 preserved or freshly photographed specimens, an updated diagnosis, a redescription, and detailed inter- and intraspecific comparisons are provided. The distribution information is revised with strong emphasis on ensuring correct species identification. Upeneus taeniopterus shows intraspecific variation in morphology and number of oblique bars on the caudal fin related to two size classes, ‘subadults’ (< 12 cm SL) and ‘adults’ (12 cm SL or larger). Indications for population differences were only detected for the smaller size class, possibly reflecting geographic developmental differences. This species is widely distributed in the Indo-Pacific from Mozambique to the Tuamoto Archipelago and from the Ryukyu Islands to Tonga and occurs mostly in very shallow subtidal sandy beach or lagoon habitats of oceanic islands and atolls. Four new records of the species for Palau, Papua (Indonesia), Tonga and Vanuatu are reported. Comparisons with all other 36 congeners revealed clear differences from U. taeniopterus in the combination of maximum size, eight meristic and colour characters, distributional range and habitat selection. The only congeneric species with similarly large maximum size and wide distributional range is Upeneus vittatus, which differs however in morphology, colour and habitat. The congeneric species differ from U. taeniopterus with sequence divergences which are comparable to those observed among genera. More genetic tissue samples are needed to further investigate the relatedness among Upeneus species and to search for phylogeographic patterns in U. taeniopterus. The need to thoroughly study the insufficiently explored subtidal sandy habitats of oceanic islands and atolls is emphasized.

Résumé [+] [-]For the goatfish genus Upeneus Cuvier 1829 (Mullidae), a new taxonomic species group called the “margarethae group” is established which can be distinguished from the six species of the most similar “tragula group” by a combination of the following characteristics: absence of dark pigmentation in the area of the first dorsal-fin tip, 21–25 total gill rakers and 28–30 lateral-line scales. Initially, three recently-described species have been included in the margarethae group: Upeneus margarethae Uiblein & Heemstra, 2010, known from the Indian Ocean including the Red Sea and from the Arafura Sea (W Pacific), U. mouthami Randall & Kulbicki, 2006, from New Caledonia and Vanuatu (W Pacific), and U. randalli Uiblein & Heemstra, 2011, from the Arabian/Persian Gulf and the inner Gulf of Oman (NW Indian Ocean). The present taxonomic review of the margarethae group analyses a large data set of 41 morphometric, 10 meristic and many colour characters obtained from 279 preserved goatfish specimens and 166 fresh-colour photos (plus a fresh-colour drawing). For the nominal species of the group, U. margarethae, a redescription of the colour patterns is provided and new records for Myanmar, Andaman Sea (NE Indian Ocean) and the Gulf of Carpentaria, N Australia (W Pacific), are reported. Three new species are described: U. caudofasciatus n. sp. from the area of the Great Barrier Reef to Torres Strait off NE Australia (Coral Sea, W Pacific), U. gubal n. sp. from the S Gulf of Suez (Northern Red Sea), and U. heterospinus n. sp. from S Indonesia to Singapore, the Gulf of Thailand, Vietnam, Philippines, China, Taiwan and Japan (W Pacific). A comprehensive alpha-taxonomic approach is adopted, considering population differences as well as intraspecific sizerelated variation in morphology and colour patterns by splitting the data set into two size classes, adults (≥ 65 mm SL) and smaller subadults. Inter- and intraspecific comparisons include statistical analyses for species and population with sufficiently large samples sizes (n ≥ 20). Colour-pattern characterization and analysis are based on photos of recently collected and deceased fish (partly associated with voucher specimens), photos obtained from active or resting fishes in situ or in a tank, and inspection of pigmentation patterns retained in preserved specimens. Species differences are elaborated under consideration of distribution patterns and the characteristics found in the closest-most population of widely distributed species such as U. margarethae, resulting in clear and consistent distinction among the six species in single or in a combination of several characteristics. Comparisons among size classes revealed species-specific patterns in morphometric, meristic and colour changes with increasing size. One species, U. heterospinus n. sp., has seven or eight spines in the dorsal fin which occur in balanced ratio across populations. This is a unique characteristic for Upeneus species which usually have either seven or eight dorsal-fin spines, respectively. The best distinction of Upeneus heterospinus n. sp. from all other congeners is reached by combined examination of dorsal-fin spines with several other characters such as barbel colour, presence of a mid-lateral body stripe, pigmentation patterns (partly retained also in preserved fish), gillraker and pectoral-fin ray numbers, and body-shape variables. The high degree of overall morphological differentation among the three most common species U. caudofasciatus n. sp., U. heterospinus n. sp. and U. margarethae, as revealed by the statistical comparisons, strongly contrasts with a still signficant, but much lower degree of differentiation among populations. The diagnostic characteristics of the margarethae group are updated and the importance to use the results of this taxonomic review in ongoing fisheries-related and ecological research is emphasized. Requirements for future taxonomic research featuring the stunning diversity of the goatfish genus Upeneus are also discussed.

Résumé [+] [-]The cuskeel genus Neobythites (Ophidiidae) is recorded for the first time from the Solomon Sea, SW Pacific, and a new species, N. solomonensis n. sp., is described based on five specimens (SL 137-166 mm) caught at 498-839 m depth in the eastern Solomon Sea. The new species is characterized by having two spines on hind margin of preoperculum, a distinct lateral body stripe and dark-brown or grey dorsal-fin margin. The most similar species is N. somaliaensis Nielsen, 1995, of which 14 specimens are compared. Neobythites solomonensis n. sp. differs from the latter in the following characters (N. somaliaensis in brackets): total vertebrae 58-61 (61-64), developed gill rakers 12-14 (9-11), orbit length 4.0-4.9 (5.0-6.1) in % SL, longest gill filament on anterior arch 4.6-5.3 (11.0-14.0) in % head length and presence (absence) of body stripe. The significance of studying colour patterns in the speciose genus Neobythites (55 valid species) is discussed.

Résumé [+] [-]The bothid flounder family Bothidae contains 20 genus and 166 species. Most of the known species have wide distributions, others are restricted to specific zones and depth ranges. Fourteen bothid specimens captured near Vanuatu Archipelago were confirmed to be Parabothus taiwanensis (Pleuronectiformes; Bothidae), a rare species described before from only five specimens from the coasts of Taiwan and recorded only from the East China Sea (Amaoka and Shen, 1993; Yamada et al., 2007). The present note provides a description of these specimens with considerable range extension for this species and a new diagnostic character.

Résumé [+] [-]Nine species of Parabothus are currently recognized. A new bothid flatfish, Parabothus rotundifrons, is described from six specimens. It is considered as a species of Parabothus because of caudal skeleton structure, moderate width of concave interorbital space in male and moderate body depth in both male and female. P. rotundifrons is easily separable from other congeners by having a lowest number of scales in the lateral line (4858), biserial teeth on the upper jaw, steep dorsal profile of the head, 8-9 non-serrate gill rakers on the low limb of the first arch, perforated membrane of dorsal and anal fins. P. rotundifrons is known from the Saya de Malha Bank, Mascareignes Plateau, Indian Ocean.

Résumé [+] [-]Setarches guentheri Johnson 1862 and Setarches longimanus (Alcock 1894) are similar to each other in sharing III, 4–6 (usually 5) anal-fin rays, a moderately deep body (29.8–42.9% of standard length; SL), three sharp spines on the lacrimal, scales absent on the lower jaw, and a fresh body color ranging from dusky-red to scarlet, S. guentheri having been considered distinguishable from the latter due to a well-developed second preopercular spine (absent or reduced in S. longimanus). Newly recognized diagnostic features of S. guentheri include the number of predorsal scales, exposed thoracic and abdominal scales, and number of ventral and caudal vertebrae. Morphological characters, including ontogenetic changes and intraspecific variation, of S. guentheri are described in detail, based on non-type specimens and all available type specimens of nominal species of S. guentheri. The distribution of S. guentheri, including a range extension to the Nazca Ridge, eastern Pacific, is also reviewed, based on previous records and examined specimens. The remarkable low genetic divergence and undefined geographical isolation in S. guentheri between the Indo-Pacific and Atlantic oceans were supported by comparison of 591 bp of the COI gene sequences from 39 and 4 specimens of S. guentheri and S. longimanus, respectively.

Résumé [+] [-]Lythrichthys Jordan and Starks 1904 (Setarchidae), previously regarded as a junior synonym of Setarches Johnson 1862, is recognized as valid, despite sharing some diagnostic characters with the latter, both genera differing from others in the family in having III, 4–6 (usually 5) anal-fin rays, the body depth at the pelvic-fin origin and interorbital width at the vertical midline of the eye 29.1–42.9% and 7.4–12.9% of standard length, respectively, snout, dorsal and ventral surface of the head naked, first lacrimal spine well developed and of similar length to the second and third spines, intestine and pyloric caeca black or grey, and swimbladder well developed. Lythrichthys differs from Setarches in having the second preopercular spine short or rudimentary (vs. well developed, of similar length to the first and third spines in Setarches), the thoracic and abdominal scales embedded (vs. exposed), the tip of the first lacrimal spine reaching the upper lip (vs. not reaching, except in juveniles), and 9 abdominal vertebrae (vs. 10). In addition, examination of all nominal species included in Setarchidae showed that five were best placed in Lythrichthys, viz. Lythrichthys longimanus (Alcock 1894), Lythrichthys eulabes Jordan and Starks 1904, Lythrichthys cypho (Fowler 1938), Lythrichthys dentatus sp. nov. and Lythrichthys grahami sp. nov., with Setarches including only Setarches guentheri Johnson 1862.

Résumé [+] [-]An annotated checklist of the chondrichthyan fishes (sharks, rays, and chimaeras) of Papua New Guinean waters is herein presented. The checklist is the result of a large biodiversity study on the chondrichthyan fauna of Papua New Guinea between 2013 and 2017. The chondrichthyan fauna of Papua New Guinea has historically been very poorly known due to a lack of baseline information and limited deepwater exploration. A total of 131 species, comprising 36 families and 68 genera, were recorded. The most speciose families are the Carcharhinidae with 29 species and the Dasyatidae with 23 species. Verified voucher material from various biological collections around the world are provided, with a total of 687 lots recorded comprising 574 whole specimens, 128 sets of jaws and 21 sawfish rostra. This represents the first detailed, verified checklist of chondrichthyans from Papua New Guinean waters.

Résumé [+] [-]With six valid species, Luciobrotula is a small genus of the family Ophidiidae, commonly known as cusk-eels. They are benthopelagic fishes occurring at depths ranging from 115–2300 m in the Atlantic, Indian, and Pacific Oceans. Among them, Luciobrotula bartschi is the only known species in the West Pacific. Three specimens of Luciobrotula were collected from the Philippine Sea, Bismarck Sea, and Solomon Sea in the West Pacific during the AURORA, PAPUA NIUGINI, and MADEEP expeditions under the Tropical Deep-Sea Benthos program, and all of them were initially identified as L. bartschi. Subsequent examination with integrative taxonomy indicates that they belong to two distinct species, with the specimen collected from the Solomon Sea representing a new species, which is described here. In terms of morphology, Luciobrotula polylepis sp. nov. differs from its congeners by having a relatively longer lateral line (end of the lateral line below the 33rd dorsal-fin ray) and fewer vertebrae (abdominal vertebrae 13, total vertebrae 50). In the inferred COI gene tree, the two western Pacific species of Luciobrotula do not form a monophyletic group. The genetic K2P distance between the two species is 13.8% on average at the COI locus.

Résumé [+] [-]Several french oceanographie expeditions have permitted to explore the bathyals lope, off the New Caledonia Island (South Western Pacifie), between 300 and 2 900 metres depth. During these recent cruises (Biocal, Biogeocal, Musorstom IV-VI, Smib, Calsub),many stalked Crinoids of different families were sampled, or observed and took in pictures with the help of the IFREMER submarine "Cyana". The New Caledonian Crinoid fauna is relatively abundant but less diversified that the fauna which was collected off the Philippines Islands (Western Pacifie). A first list of this stalked Crinoid fauna (13 taxa identified) is established in this paper with a description of three new species (Metacrinus l evii n. sp., Caledonicrinus vaubani n. sp., Proeudesicrinus lifouensis n. sp.) belonging to two new genera (Caledonicrinus n. gen., Proeudesicrinus n. gen.). Further descriptions are supplied for some taxa (Naumachocrinus hawaiiensis, Gymnocrinus, Guillecrinus).Nevertheless, New Caledonian stalked Crinoid fauna appears to be the most archaic in there cent oceans with close relationship with the fossil fauna of the Mesozoic Mesogean Sea. Many taxa have inneed very ancient affinities. Guillecrinus sp. Is the only living representative of the Paleozoic subclass Inadunata. Proisocrinus ruberrimus, Gymnocrinus richeri, Proeudesicrinus lifouensis have relationships with Jurassic adaptative radiation. Caledonicrinus vaubani is the most archaic (late Cretaceous affinities) and the shallower species of the deep-sea family Bathycrinidae. Consequently, historical biogeography and phylogeny of the Indo-Pacific stalked Crinoids through Post-Paleozoic times are discussed with regard to the origin of New Caledonia fauna.

Résumé [+] [-]Les calcaires à entroques correspondent à des accumulations d'ossicules d'échinodermes. Ce sont principalement des calcaires crinoïdiques, mais occasionnellement les débris d'astérides peuvent dominer. Le bon niveau d'organisation des ossicules de crinoïdes permet leur reconnaissance et leur interprétation écologique à partir de l'analyse de lames minces, ce qui étend leur intérêt à l'étude des forages. Pendant longtemps, ces animaux ont été pris pour des "fossiles vivants" réfugiés dans les profondeurs océaniques. Cela faisait obstacle à toute interprétation actualiste des calcaires à entroques. En fait, les faunes fossiles habitaient le plus fréquemment les plate-formes externes et les talus continentaux, donc des milieux similaires à ceux des faunes actuelles, mis à')part quelques périodes particulières (Roux, 1979). Ce changement d'optique ouvre la voie à l'analyse des modèles fournis par l'océan actuel en tant que références utiles à l'interprétation paléoécologique des faunes fossiles de crinoïdes (Roux, 1982 et 1987). Celles-ci enregistrent avec précision des points cruciaux de l'histoire des marges continentales. La bonne connaissance des faunes actuelles va favoriser une lecture correcte des annales paléontologiques. Elle fournira un remarquable outil pour apprécier les paléobathymétries, pour reconstituer l'évolution morphologique des marges et pour comprendre la géométrie et la localisation des réservoirs potentiels d'hydrocarbures que peuvent être les calcaires à entroques.

Résumé [+] [-]Numerous recent oceanographic expeditions have provided much new data on the morphology and ecology of stalked crinoids. Of the many taxa that have been sampled, the order Cyrtocrinida represents one of the most peculiar, as a majority of its species are archaic, with Mesozoic afffinities. In this study, we examine in detail the morphology of several members of the cyrtocrinid family Holopodidae, provide biometric analyses, and amend the diagnoses of the family and one of its constituent genera, Cyathidium. The family Holopodidae consists of only two genera, Cyathidium and Holopus. As the latter genus has been previously studied in some detail, here we present only an abbreviated description of this taxon; the study focuses primarily on Cyathidium. Of the four Cyathidium species examined, one, C. pourtalesi, is a newly described extant species, while another, C. senessei, is a fossil species. All specimens were examined using optical and scanning electron microscopy; because of their taxonomic importance, special attention was given to the morphology and biometry of the dorsal cup, and the arm and pinnular joints. Availability of Cyathidium specimens in different ontogenic stages, has allowed us to conclude that heterochronic processes played an important role in the evolution of this genus. Data on ontogenic stages of Cyathidium made it possible to make a comparison between different species within this genus, between Cyathidium and Holopus and between the Holopodidae and the remaining Cyrtocrinids.

Résumé [+] [-]The stalk morphology of the deep-sea stalked crinoid Guillecrinus changes a lot from juvenile to adult. As a result of its unusual morphology among the extant crinoids, its taxonomic and phylogenetic affinities remain unsettled. Distinctive morphological changes characterize the various growth stages in stalked crinoids. We conduct and discuss a detailed ontogenetic analysis of the stalk of the two species (Guillecrinus neocaledonicus and G. reunionensis) of this Indo-Pacific genus, which was observed in its environment during submersible dives off New Caledonia. Analyses examined (1) morphological changes, (2) the degree of change in morphology, (3) architectural constraints, and (4) the functional constraints related to environmental factors. The relations between three levels of integration were examined: the ossicle (columnal), the stalk, and the complete individual. The changes in level of organization were estimated. The analysis reveals that the external stalk morphology of Guillecrinus goes from a pronounced xenomorphic type in juveniles, characterized by diversified columnal articulations, which provide the proximal and distal part of the stalk with a considerable degree of flexibility, to a dominant homeomorphic type in adults, characterized by columnal articulations which allow little or no movement. This ontogenetic change through a mosaic of heterochronic developments corresponds with a change in the hydrodynamic environment, from a turbulent to a laminar water flow, and from nutritional contraints. The extensive development of deep ligament fossae in adults and in the distal stalk of juveniles corresponds to a relatively low allocation of energy to the skeleton, rather than a functional necessity. Proximal columnals in juvenile Guillecrinus display characteristics of adult Hyocrinidae. Distal columnals exhibit the typical morphology observed in Bourgueticrinina. Juveniles stages of both proximal and distal columnals show a high degree of specialization (derived characters). Well-supported classifications have typically placed the Bourgueticrinina and the Hyocrinidae in two very dissimilar groups. Specific characteristics from the three very different families Bathycrinidae, Guillecrinidae and Hyocrinidae appear to be expressed either separately (Hyocrinus or Bathycrinus) or together (Guillecrinus). Their expression appears to depend on functional and environmental constraints. The transformation of columnals from juvenile to adult shows the important role of hypermorphic processes. However, no evidence of phylogenetic recapitulation was observed. Does the evidence presented here support or disprove current taxonomic interrelationships? How does morphology relate to ontogeny? Is heterochrony involved?

Résumé [+] [-]Ontogeny of non-muscular brachial articulations in extant species of Balanocrininae, i.e., Neocrinus decorus, Neocrinus blakei and Hypalocrinus naresianus (Crinoidea, Isocrinida), is described using SEM observations. All three species share embayed synarthries and symplexies (previously only known in crinoid stalks) showing a radiating crenularium pattern in their proximal arms but differ in several important ways. Neocrinus decorus has a shallow simple symmorphy affecting symplexies, and embayed synarthries. During the latest ontogeny of embayed synarthries, irregular syzygial ridges appear on the aboral segment of the fulcral ridge. Neocrinus blakei and H. naresianus share a peculiar sharp deep symmorphy superimposed on symplexies, and synarthries with a more complete single fulcral ridge that only appears late in ontogeny. Comparison with other crinoid taxa that have more advanced arm axial synarthries shows that this ontogenetic trajectory is restricted to paedomorphic stages in extant balanocrinins. An embayed synarthry seems to be derived from the earliest developmental stage of the radiating symplexial crenularium via hypermorphosis of a single crenula. An embayed synarthry is, therefore, a symplesiomorphy based on paedomorphic stage of development; it thus lacks phylogenetic significance, and should be abandoned as a major character in the classification of Isocrinida. The most advanced brachial synarthries shared by distant crinoid taxa mainly represent a homoplasy under morphofunctional constraints. However, they could result from different ontogenetic trajectories, which have only rarely been investigated. Another distinctive articulation feature, the peculiar sharp deep symmorphy observed in extant balanocrinins is a derived character known in a few fossil isocrinids beginning in the Middle Jurassic. We question its phylogenetic significance and suggest that it has developed repeatedly via iterative evolution in Isocrinida. Therefore, because these three extant balanocrinin species share the same ontogenetic trajectories of arm and stalk ligamentary articulations, and differ only in various states of heterochronic development of a few characters, we treat them as belonging to the same genus. We, therefore, consider Hypalocrinus as a junior synonym of the genus Neocrinus.

Résumé [+] [-]The stalked crinoid fauna off New Caledonia (S.W. Pacific): a bathyal relic from the Mesogean Sea. During 1985, MUSORSTOM V and BIOCAL cruises were conducted on the bathyal slope off New Caledonia. They revealed a benthic fauna abunding in stalked crinoids. The following living species are listed : Saracrinus nobilis, Metacrinus aff. Serratus, Diplocrinus alternicirrus, Proisocrinus ruberrimus, Guillecrinus sp., Bathycrinus sp. And Zeuctocrinus sp. One additional species is only known from many brachials which are well-preserved into a bioclatic carbonate sediment: Gymnocrinus sp. Four taxa have very ancient affinities. Guillecrinus sp. is the only living representative of the paleozoic subclass Inadunata. P. ruberrinmus and Gymnocrinus have relationships with jurassic adaptative radiation. Zeuctocrinus sp. is the most archaic (late Cretaceous affinities) and the shallower species of the deep-sea family Bathycrinidae. The stalked crinoid fauna of New Caledonia appears to be the most archaic in recent oceans with close relationships with the fossil fauna of the mesozoic Mesogean Sea. Consequently, historical biogeography of the Indo-Pacific stalked crinoids through Post-Paleozoic times is discussed with regard to the origin of New Caledonia fauna.

Résumé [+] [-]A recent representative (Echinodermata) of the jurassic family Hemicrinidae: Gymnocrinusricheri nov. sp. from the bathyal slope, off the New Caledonia Island (South Western Pacific) Gymnocrinus richeri nov. sp. is a new stalked crinoid (Crinoidea) with a short stem and a very asymmetrical crown, a feature which was not yet observed in the recent fauna. The peculiar morphology of the brachials suggests an attribution to the jurassic genus Gymnocrinus which was only known from a few disassociated ossicles. The complete specimens permit to confirm the close affinities between Cyrtocrinus, Gymnocrinus and Hemicrinus, three genera which may be gathered into the family Hemicrinidae (Jurassic-Lower Cretaceous). That strange crinoid was discovered from the epibathyal slope, off New Caledonia at a depth of 470m.

Résumé [+] [-]Echinodermata : Pentacrinidae crinoids procured by the MUSORSTOM 2 and CORINDON 2 expeditions. During MUSORSTOM 2 and CORINDON 2 expeditions (West Philippines for the former, Makassar channel for the latter) many stalked crinoids of the family Pentacrinidae were sampled. They are more diversified and comparatively more abundant than the fauna which was collected during the MUSORSTOM 1 expedition. The samplings come from depths between 170 and 970 meters. Four genera are represented : Diplocrinus, Hypalocrinus, Metacrinus and Saracrinus. Detailed descriptions of the ten following species are given : D. alternicirrus, D. sibogae, H. naresianus, M. interruptus, M. musorstomae, M. nodosus, M. serratus, M. wyvillii, S. angulatus and S. superbus. For each specimen, data on morphological features, biometry, arm branching and ossicle articulations are given. Stalk and arm joints were observed under, scanning electron microscope, especially stem synostosis with regard to their importance for taxonorny. Sometimes, some peculiar growth patterns appear to be a consequence of fast regeneration. Such features are illustrated by the proximal part of the stalk of a few specimens belonging to S. angulatus and M. wyvillii. As numerous individuals of each species were collected, it was possible to study the variation of crown and stem characters. The morphological features and their variability seem to be depth related. The bathymetrical distribution of Pentacrinidae in the Western Pacific province is examined and discussed. Intraspecific polymorphism with regard to external stem morphology and arm organization is suggested for a few species of this biogeographical province. The number of recognized species might be reduced because sorne of them might be interpreted as a consequence of ecophenotypic or geographical variations. So, in the subfamily Metacrininae, S. acutus, S. cingulatus, S. batheri and S. suluensis might be synonyms of S. angulatus. It is also suggested that S. nobilis (S. varians and S. superbus included) shows intraspecific polymorphism or large morphological variations through a wide depth range. For the genus Metacrinus, simplification of the species number is more difficult to effect because each phenotype frequently seems to be clearly distinguished. Nevertheless, M. interruptus and M. musorstomae are very similar and the latter might be an ecophenotype of the former. M. costatus and M. serratus are also two species with large morphological affinities; the first species seems to be a morph living in deeper environment. M. rotundus might include M. multisegmentatus and M. cyaneus. Stem and arm morphological variations linked to bathymetry are also interpreted in terms of adaptative strategy (r and K selection). For pentacrinids, two unstability limits are suggested from their depth repartition : the upper boundary (about 100 meters) couId correspond to hydrodynamic vulnerability threshold, the lower (about 1500-2500 meters) to the trophic vulnerability limit, the food becoming too scarce. In one genus, species living close to these two unstability limits have a very important morphological variability (for example : M. rotundus, M. wyvillii). In the Western Pacifie, the most stable depth range for these crinoids could be situated between 300 and 600 meters with development of K strategy (M. serratus). Biogeographical repartition of these species is analysed from such a point ofview. Typical r strategy species (M. rotundus, M. wyvillii, S. nobilis, H. naresianus) have the largest geographical repartition. S. nobilis seems to be the species with the most eurybathic pattern with polymorphie characters. Taxonomy, paleoecology and biostratigraphy of fossil stalked crinoids must be reconsidered and discussed as a consequence of these results.

Résumé [+] [-]Several French oceanographic expeditions have enhanced the exploration of the bathyal slope, off New Caledonia (South Western Pacific). During these recent cruises (BIOCAL, BIOGEOCAL, MUSORSTOM 4-6, CHALCAL 2, SMIB 3-4, CALSUB), many stalked Crinoids of different orders and suborders (Isocrinida Pentacrinidae, Millericrinina, Bourgueticrinina, Cyrtocrinida and incertae sedis) have been sampled, or observed and photographed with the help of the IFREMER submersible « Cyana ». The samples come from depths between 230 and 3700 meters but the most numerous faunas have been gathered in the 200-600 meters bathymetrical interval. Fourteen genera are represented in the crinoid fauna of New Caledonia which have never been inventoried or illustrated : Metacrinus, Saracrinus, Diplocrinus, Proisocrinus, Caledonicrinus, Porphyrocrinus, Naumachocrinus, Bathycrinus, Gymnocrinus, Holopus, Proeudesicrinus, Thalassocrinus, Hyocrinus, Guillecrinus. Some of these are only known from the New Caledonian bathyal slope ( Caledonicrinus, Proeudesicrinus). Until now the genus Holopus was known only from the Tropical Western Atlantic Ocean and the genus Guillecrinus was known only from the bathyal slope of the Indian Ocean. Detailed descriptions of sixteen species are given. Three taxa are illustrated for the first time : Holopus alidis sp. Nov., Guillecrinus neocaledonicus sp. Nov. And Hyocrinus cyanae sp. Nov. Further descriptions are supplied for some species (Naumachocrinus hawaiiensis, Gymnocrinus richeri) and for three recently described new taxa from New Caledonia off shore (Metacrinus levii, Caledonicrinus vauhani, Proeudesicrinus lifouensis). The New Caledonian Pentacrinid fauna is abundant but ess diverse than the rich fauna which has been collected off the Philippines (Western Pacific). Only four species are known from New Caledonia : Metacrinus levii. Metacrinus musorstomae, Saracrinus nohilis, Diplocrinus allernicirrus. Cyrtocrinida are very numerous between 300-500 meters, especially Gymnocrinus richeri and Holopus alidis. This bathymetrical interval is also occupied by Caledonicrinus vauhani. The shallower species of the deep-sea family Bathycrinidae and by Porphyrocrinus. Proisocrinus ruberrimus. Naumachocrinus hawaiiensis. Bathycrinus. Hyocrinidac with Hyocrinus, Thalassocrinus and the incertae sedis Guillecrinus neocaledonicus are living in the deep sea (below 1000 meters). Nevertheless, the New Caledonian stalked Crinoid fauna appears to be the most archaic in the recent oceans showing a close relationship with the fossil fauna of the Mesozoic Mesogean Sea. Many taxa have indeed very ancient affinities : Guillecrinus is the only living representative of the Paleozoic subclass Inadunata. Proisocrinus ruberrimus. Gymnocrinus richeri and Proeudesicrinus lifouensis have relationships with Jurassic adaptative radiation, Caledonicrinus vauhani is the most archaic (late Cretaceous affinities) species of the deep-sea family Bathycrinidae. Consequently, historical biogeography and phylogeny of the Indo-Pacific stalked Crinoids, through Post-Paleozoic times, are discussed with regard on the origin of New Caledonia fauna.

Résumé [+] [-]Background: In Metazoa, mitochondrial markers are the most commonly used targets for inferring species-level molecular phylogenies due to their extremely low rate of recombination, maternal inheritance, ease of use and fast substitution rate in comparison to nuclear DNA. The mitochondrial control region (CR) is the main non-coding area of the mitochondrial genome and contains the mitochondrial origin of replication and transcription. While sequences of the cytochrome oxidase subunit 1 (COI) and 16S rRNA genes are the prime mitochondrial markers in phylogenetic studies, the highly variable CR is typically ignored and not targeted in such analyses. However, the higher substitution rate of the CR can be harnessed to infer the phylogeny of closely related species, and the use of a non-coding region alleviates biases resulting from both directional and purifying selection. Additionally, complete mitochondrial genome assemblies utilizing next generation sequencing (NGS) data often show exceptionally low coverage at specific regions, including the CR. This can only be resolved by targeted sequencing of this region. Results: Here we provide novel sequence data for the echinoid mitochondrial control region in over 40 species across the echinoid phylogenetic tree. We demonstrate the advantages of directly targeting the CR and adjacent tRNAs to facilitate complementing low coverage NGS data from complete mitochondrial genome assemblies. Finally, we test the performance of this region as a phylogenetic marker both in the lab and in phylogenetic analyses, and demonstrate its superior performance over the other available mitochondrial markers in echinoids. Conclusions: Our target region of the mitochondrial CR (1) facilitates the first thorough investigation of this region across a wide range of echinoid taxa, (2) provides a tool for complementing missing data in NGS experiments, and (3) identifies the CR as a powerful, novel marker for phylogenetic inference in echinoids due to its high variability, lack of selection, and high compatibility across the entire class, outperforming conventional mitochondrial markers.

Résumé [+] [-]We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by phylogenetic methods. The molecular data were compiled from concatenated nuclear-encoded 18S rDNA, internal transcribed spacer 1, 5.8S rDNA, and internal transcribed spacer 2, together with part of mitochondrial 16S rDNA, and comprised 3,593 sites, of which 313 were parsimony-informative. The molecular and morphological analyses include data from the bourgueticrinid Bathycrinus; the antedonid comatulids Dorometra and Florometra; the cyrtocrinids Cyathidium, Gymnocrinus, and Holopus; the isocrinids Endoxocrinus, and two species of Metacrinus; as well as from Guillecrinus and Caledonicrinus, whose ordinal relationships are uncertain, together with morphological data from Proisocrinus. Because the molecular data include indel-rich regions, special attention was given to alignment procedure, and it was found that relatively low, gene-specific, gap penalties gave alignments from which congruent phylogenetic information was obtained from both well-aligned, indel-poor and potentially misaligned, indel-rich regions. The different sequence data partitions also gave essentially congruent results. The overall direction of evolution in the gene trees remains uncertain: an asteroid outgroup places the root on the branch adjacent to the slowly evolving isocrinids (consistent with palaeontological order of first appearances), but maximum likelihood analysis with a molecular clock places it elsewhere. Despite lineage-specific rate differences, the clock model was not excluded by a likelihood ratio test. Morphological analyses were unrooted. All analyses identified three clades, two of them generally well-supported. One well-supported clade (BCG) unites Bathycrinus and Guillecrinus with the representative (chimaeric) comatulid in a derived position, suggesting that comatulids originated from a sessile, stalked ancestor. In this connection it is noted that because the comatulid centrodorsal ossicle originates ontogenetically from the column, it is not strictly correct to describe comatulids as "unstalked" crinoids. A second, uniformly well-supported clade contains members of the Isocrinida, while the third clade contains Gymnocrinus, a well-established member of the Cyrtocrinida, together with the problematic taxon Caledonicrinus, currently classified as a bourgueticrinid. Another cyrtocrinid, Holopus, joins this clade with only weak molecular, but strong morphological support. In one morphological analysis Proisocrinus is weakly attached to the isocrinid clade. Only an unusual, divergent 18S rDNA sequence was obtained from the morphologically strange cyrtocrinid Cyathidium. Although not analysed in detail, features of this sequence suggested that it may be a PCR artefact, so that the apparently basal position of this taxon requires confirmation. If not an artefact, Cyathidium either diverged from the crinoid stem much earlier than has been recognised hitherto (i.e., it may be a Palaeozoic relic), or it has an atypically high rate of molecular evolution.

Marine natural products : chemical constituents from New Caledonian deep-water species, in Troisième Symposium sur les substances naturelles d'intérêt biologique de la région Pacifique-Asie, Nouméa, CNRS-ORSTOM
Résumé [+] [-]During our ongoing program of searching for new bioactive molecules from new-caledonian marine invertebrates, the opportunities occured recently to examine a "living fossil" crinoid Gymnocrinus richeri, discovered by B. Richer de Forges at 520m depth. In vivo this crinoid is saffron yellow with the stalk darker and tentacles dark yellow-green inside. A few minutes after collecting, outside the water, it turns readily dark-green. The green pigments, extractable with methanol, turned violet on very mild acidification. In this communication the structure of five violet pigments, which constitute a novel group of brominated phenanthroperylenequinones, will be discussed. These pigments have interesting stereochemical features, i.e. the axial chirality generated by the phenanthroperylenequinone system forced into a non planar helical shape. The assignment of the stereochemistry based on CD, NMR data and correlation with natural occuring perylenequinones will he presented. There is also considered the possible relationship between the violet pigments and the native yellow and green ones. A second "living fossil" organism from New Caledonia which we had the opportunity to examine is the starfish species Tremaster novae caledoniae collected at 530m depth off Nouméa. This organism contains a group of unusual steroids in which one hydroxyl group is sulphated, one is acetylated and a third one is esterified with glucose-I-phosphate. The results of the chemical investigation of the sponge Jereicopsis graphidiophora (new genus) and Erylus sp. collected at ca. 500m depth off Nouméa, will he also presented. While the 3B- hydroxy steroids were totally absent, the extracts of J. graphidiophora contain unique 38- hydroxy steroids. L'wo of them combine the unique 38- methoxyl group with a rare secostructure. The polar extracts of Erylus sp. contain two terpenoid oligoglycosides. Sequential analysis of the oligosaccharide portions was achieved by modern 2D-NMR techniques.

Résumé [+] [-]Beside tremasterols A-C, first phosphated steroid glycosides to be found from a natural source, the starfish Tremaster novaecaledoniae contains nine more novel steroid constituents. One, 4, is related to the previous tremasterols by having the same 6-O-phosphated function. A secound of compounds (5-8) possesses the same 3,6-disulphated 3 beta, 6 alpha, (22R)- trihydroxycholestane structure, differing for the presence of the delta 9 double bond in 5 and 6 and for the acetate conjugation of the 22-hydroxyl group in 6 and 8. The remaining compounds 9-12 are highly hydroxylated steroids, among which the steroids 11 features the cis A/B ring junction, never encountered before among steroids derived from starfishes.

Résumé [+] [-]Based on the specimens collected during three deep-sea cruises, and deposited at the Muséum National d’Histoire Naturelle (MNHN) in Paris, we analysed the diversity of benthic communities within the EEZ of French Polynesia. The literature and the MNHN database allowed us to inventory 471 species of invertebrates, among which 169 were newly described. We mainly found data for Mollusca, Crustacea, Brachiopoda and Crinoidea. We also found samples from other taxa, which still remain unidentified within the collections of the MNHN. Although this inventory is incomplete, we demonstrate that the deep waters of French Polynesia host unique benthic communities and endemic species. Using diversity and multivariate analyses, we show that the deep-sea benthic communities are structured by depth, habitats, geography and also by the presence of polymetallic crust. Furthermore, by focusing on the molluscs of the central area of French Polynesia, we show that the spectrum of shell size differs among deep-sea habitats. Specifically, shells tend to be smaller on encrusted seamounts than on island slopes. Together with the size range of organisms, low abundance, rarity and endemism designate these habitats as sensitive. These results should thus be taken into account in the evaluation of the expected impact of mining activities on biological communities.

Grasshoff M. & Bargibant G. 2001. Coral Reef Gorgonians of New Caledonia. Faune marine de Nouvelle-Calédonie. IRD, Paris, 339 pp.
Résumé [+] [-]The New Caledonian reefs are among the largest reef system of the world, second only to the Great Barrier Reef. The long-term programs about the reef fauna around New Caledonia carried out by Orstom (now .IRD), Nouméa, have had a broad range of goals. A main part of this research focused on investigations of the chemical compounds that can be found in sessile animals such as sponges, octocorals, and ascidians. However, our knowledge of these animals also has been enormously increased: hardly any species of macroscopic animais escaped the attention of divers who have spent thousands of hours under water, observing, photographing, and collecting the various animais of the reef habitat. These activities have a special importance for octocoral research. Descriptions of octocorals species are based almost exclusively on dried or fluid-preserved specimens stored in museum collections. Observations in marine habitats feveal the wide gap between the characters of living octocorals and traditional descriptions. The appearance of living corals, including octocorals, is quite different from that of dead specimens, due partly to the hydraulic properties of polyps, partly to changes in colour after preservation. The discrepancy may be 50 great that even an experienced taxonomist may not recognize a well-known genus of octocoral when faced with the living animal. Research on the shallow water octocorals of New Caledonia shows how this gap can be bridged. Little was known about them until the activities of Orstom (now IRD) raised our knowledge to a new level. The appearance in life of all corals was recorded photographically before they were collected. For the first time this procedure has been applied throughout for recording an entire marine fauna. The gorgonian part is presented in this volume: good records of living octocorals in their underwater habitats correlated closely with traditional taxonomic knowledge. Not all of the technical problems of recognizing living octocorals have been solved in this way, but the procedures carried out by IRD may be taken as an example for further octocoral research in shallow water habitats.

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification. Frontiers in Marine Science 8: 749078. DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

Résumé [+] [-]Ten marine polyhydroxysteroids, 1-10, of which two, 1 and 5, are known compounds previously isolated from starfish, have been isolated from the deep water starfish Styracaster caroli, collected at a depth of 2000 m off New Caledonia. The 3ß,5,6ß-trihydroxy functionality is the common element in these steroids, and additional hydroxylgroups were found at positions 8,15a (or ß) and lbß. Greater differences are observed in the structure of the sidechains, which showed multiple functionalities and different alkylationpatterns. Characterization was accomplished by fabms and 'H- and "C-nmr spectroscopy, with the assignments of the configurations to the stereogenic centers of the side-chains being made by 'H-nmr comparison with appropriate models and on analysis of their derivatives with a chiral reagent.

Résumé [+] [-]The genus Tremaster has several primitve features and show clear relationships with middle Jurassic fossils. Tremasters are unique among recent forms in having internal calcified duct in each interradius. Each duct opens upwards and downwards into the surrounding medium through two interradial apertures. Owing to the presence of these ducts, asteroids presumably are able to change their body shape while having their margin closely appressed to the substrate. Gametes are released into these ducts which can be used as brood chambers. Such internal calcified ducts are assumed to be modified interradial speta.

Résumé [+] [-]A new species of Asterodiscides, A. bicornutus n. sp., is reported from Espiritu Santo, Vanuatu, in the tropical southwest Pacific, a region which may qualify as a southeastern extension of the zone of maximum marine biodiversity known as the coral triangle. The biogeography of the genus, in particular its apparent absence from the equatorial Indo-Malay and west Pacific region and the occurrence of disjunct distributions, is re-examined. An earlier contention that this anomalous distribution pattern could result from shelf extinctions during glacial maxima, with subsequent failure to re-invade the core diversity region during high sea level stands, is rejected. Tropical Asterodiscides species generally occur at depths corresponding to the ocean thermocline, an undersampled zone that is deeper in the west Pacific. Further intensive surveys for these comparatively rare asteroids in the core biodiversity region, sampling deeper shelf areas and targeting upwelling zones, together with supportive molecular ana yses an investigation of biology (particularly reproductive strategies), are considered essential for a more complete understanding of the biogeography and speciation of this genus.

Résumé [+] [-]New material of Brisingaster robillardi de Loriol 1883, including juveniles, allows a more complete description of the species. Papulae, obscured in the holotype and previously unknown for this taxon, are present. Abactinal plate arrangements provide new autapomorphies for the genus Brisingaster. Scanning electronic microscope photographs of pedicellariae are described and compared with those of Novodinia antillensis. The range of B. robillardi is extended to New Caledonia, Western Australia and Amami-o-shima, Japan. Morphological variation is present between material from the Pacific and the Indian Ocean. Novodinia helenae Rowe, 1989 is synonymized with B. robillardi. New phylogenetic evidence also supporrs a new family, the Brisingasteridae, which tentatively includes Brisingaster and Novodinia.

Résumé [+] [-]A phylogenetic analysis of 11 taxa and 31 characters resulted in a single most parsimonious tree that supports monophyly of the goniasterid genera Iconaster and Glyphodiscus. Four new species, Glyphodiscus magnificus n. sp., Glyphodiscus pentagonalis n. sp., Iconaster uchelbeluuensis n. sp., and Iconaster vanuatuensis n. sp., are described and two species are synonymized. At least three species within the genus Iconaster appear to have invaded shallower water from a deeper-water ancestry. Glassy tubercles, similar to those interpreted as photoreceptors in ophiuroids and other goniasterids, are present in the shallow-water Iconaster clade. Glassy tubercles are largely absent in the deeper-water sister and outgroup taxa, suggesting their occurrence is related to photic zone or shallow-water occupation. Biogeographic patterns as presently known suggest that diversification in Iconaster and Glyphodiscus has been restricted to the central and south Pacific regions.

Résumé [+] [-]A phylogenetic analysis of 13 taxa and 32 characters resulted in a single most parsimonious tree that supports monophyly of the goniasterid (Echinodermata, Asteroidea) genus Circeaster Koehler, 1909 and supports re-establishment of the genus Lydiaster Koehler, 1909. The phylogeny supports monophyly of the ingroup, including 10 species, six of which, C. kristinae n. sp., C. helenae n. sp., C. arandae n. sp., C. loisetteae n. sp., C. sandrae n. sp., and C. pullus n. sp., are new. Phylogenetic results support diversification into the Indian, Pacific, and Atlantic ocean basins. The phylogeny is constrained by a sister taxon with a Cretaceous fossil occurrence and two geologic events, including the closure of the Indonesian seaway and formation of the Panamanian isthmus. These events formed barriers limiting or preventing larval dispersal between the Indian/Pacific and the Pacific/Atlantic oceans. Larval dispersal through a deep-sea environment was a signifi cant consideration for estimating timing constraints from paleoenvironments. Based on fossil constraints, ancestry for the lineage is suggested as early as the Late Cretaceous with subsequent diversification in the Cenozoic. In situ observations of Circeaster perched on bare deep-sea coral skeletons and morphological similarities with other known corallivorous goniasterids suggest important ecological roles in the deep-sea.

Résumé [+] [-]Morphology-based phylogenetic hypotheses developed for living and fossil goniasterid asteroids have provided several unique opportunities to study bathymetric and biogeographic shifts for an ecologically important group of prominent, megafaunal invertebrates. A cladistic analysis of 18 ingroup taxa employing 65 morphological characters resulted in a single most parsimonious tree. The tree supports assignment of the Atlantic Tosia parva (Perrier, 1881) and the Pacific Tosia queenslandensis Livingstone, 1932 to new, separate genera. The phylogenetic tree supports offshore to onshore bathymetric shifts between basal and derived taxa. The phylogeny is also consistent with historical events surrounding the separation of Antarctica from Australia and South Africa. Buterminaster Blake & Zinsmeister, 1988 from the Eocene La Meseta Formation, Antarctic Peninsula, was included in the phylogenetic analysis and is now supported as the only fossil species in the genus Pentagonaster Gray, 1840. Pentagonaster stibarus H. L. Clark, 1914 is separated from synonymy with P. dubeni Gray, 1847 and resurrected as a valid species. The new genus, Akelbaster, gen. nov., shows unusual new structures that resemble cribiform organs, although their function has not been determined. One specific ingroup lineage, including Tosia and Pentagonaster, attains a much larger adult size than those of its sister-taxa, suggesting that Cope’s rule may apply to asteroids within this clade. Pentagonaster and related genera are revised. Descriptions of four new genera and three new species are presented, including: Akelbaster novaecaledoniae, gen. nov., sp. nov., Ryukuaster onnae, gen. nov., sp. nov., Eknomiaster beccae, sp. nov., Pawsonaster parvus, gen. nov., comb. nov. and Anchitosia queenslandensis, gen. nov., comb. nov.

Résumé [+] [-]We present a comprehensively sampled three-gene phylogeny of the monophyletic Forcipulatacea, one of three major lineages within the crown-group Asteroidea. We present substantially more Southern Hemisphere and deep-sea taxa than were sampled in previous molecular studies of this group. Morphologically distinct groups, such as the Brisingida and the Zoroasteridae, are upheld as monophyletic. Brisingida is supported as the derived sister group to the Asteriidae (restricted), rather than as a basal taxon. The Asteriidae is paraphyletic, and is broken up into the Stichasteridae and four primary asteriid clades: (1) a highly diverse boreal clade, containing members from the Arctic and sub-Arctic in the Northern Hemisphere; (2) the genus Sclerasterias; (3) and (4) two sister clades that contain asteriids from the Antarctic and pantropical regions. The Stichasteridae, which was regarded as a synonym of the Asteriidae, is resurrected by our results, and represents the most diverse Southern Hemisphere forcipulatacean clade (although two deep-sea stichasterid genera occur in the Northern Hemisphere). The Labidiasteridae is artificial, and should be synonymized into the Heliasteridae. The Pedicellasteridae is paraphyletic, with three separate clades containing pedicellasterid taxa emerging among the basal Forcipulatacea. Fossils and timing estimates from species-level phylogeographic studies are consistent with prior phylogenetic hypotheses for the Forcipulatacea, suggesting diversification of basal taxa in the early Mesozoic, with some evidence for more widely distributed ranges from Cretacous taxa. Our analysis suggests a hypothesis of an older fauna present in the Antarctic during the Eocene, which was succeeded by a modern Antarctic fauna that is represented by the recently derived Antarctic Asteriidae and other forcipulatacean lineages.

Résumé [+] [-]Modern goniasterids are the most numerous of living asteroids in terms of described genera and species and they have important ecological roles from shallow to deep-water marine habitats. Recent MNHN expeditions and historical collections in the USNM have resulted in the discovery of 18 new species, three new genera and multiple new occurrence records from the western Indian Ocean region including Madagascar, Glorioso and Mayotte islands, Walters Shoal, South Africa, and Somalia. This report provides the first significant contribution to knowledge of deep-sea Asteroidea from the Indian Ocean since the late 20th Century. Several deep-sea species, previously known from the North Pacific are now reported from the western Indian Ocean. Gut contents from Stellaster and Ogmaster indicate deposit feeding. Feeding modes of this and other deep-sea species are discussed. Comments are made on fossil members of included taxa. A checklist of Indian Ocean Goniasteridae is also included.

The new genus Astroglypha is described for A. pyramidata but the genus also includes the Atlantic Tamaria passiflora, which is reassigned herein. Pauliastra n. gen. is designated as a replacement for the homonym issue with Pauliella. New occurrences and synonymies are addressed for taxa related to New Caledonia, Rapa Nui and adjacent regions. A morphology based phylogenetic analysis agrees with prior work which placed Goniaster among the Asterodiscididae and posits biogeographic relationships among asterodiscidid genera. Implications for the Goniasteridae and placement of Goniaster among asterodiscidid genera are discussed. Biogeography and relationships among taxa from Rapa Nui and New Caledonia are reviewed. In situ observations from species observed from Rapa Nui are included.

The families Comasteridae, Asterometridae, Calometridae and Thalassometridae, in Crosnier A.(Ed.), Résultats des campagnes MUSORSTOM 21. Mémoires du Muséum national d'Histoire naturelle 184:627-702, ISBN:2-85653-526-7
Résumé [+] [-]Fifteen species of comatulid crinoids in eleven genera and four families collected in 180-800 m by the joint French-Indonesian KARUBAR Expedition to the Kai and Tanimbar Islands, Indonesia (October 1991), are described in detail. The specimens represent the most important collection of bathyal comatulids from the East Indies in the second half of the twentieth century. The material described herein comprises four species of Comasteridae, one Asterometridae, two Calometridae and eight Thalassometridae. One species of calometrid (Neometra xenocladia sp. nov.) is described as new. FiveTpecies are recorded for the first dme since they were originally collected. Four thalassometrids (Aglaometra valida, Oceanometra annandalei, Cosmiometra philippinensis and Stenometra cristata) together account for 75% of identified specimens, reflecting this family's importance to the outer shelf-upper bathyal comatulid fauna of the tropical Indo-Western Pacific. The substantial amount of material of several species, notably A. valida and O. annandalei, permits a better understanding of morphological variability than previously. Statistical analyses of several sipposedly diagnostic characteristics including aspects of calyx form and number of cirri, reveal substantial variation. We place several taxa in sinonymy as a result. SIM studies of different ossicles have been made for the first time for A. valida and O. annandalei. The preliminary results show that great morphological differences exist within the family. Three species (Stiremetra breviradia, Palaeocomatella hiwia and Cosmonuetra iole) are recorded from Indonesian waters for the first time. Moreover, most of the KARUBAR comatulids represent geographical and bathymetrical range extensions.

Résumé [+] [-]Three genera of unstalked crinoids, Zenometra, Sarametra and Psathyrometra, formerly included in the subfamily Zenometrinae of the family Antedonidae, are removed and placed in a distinct family, the Zenometridae. Diagnostic features include a cavernous centrodorsal cavity, a complete basal circlet with a large central lumen and cirrus sockets with a concave fulcral bowl around the lumen. Sarametra nicobarica is synonymized under S. triserialis, which is redescribed in detail. Psathyrometra is redefined and includes only the species P. fragilis, P. congesta and P. bigradata, which are redescribed. P. erythrizon is synonymized under P. fragilis. The four other species formerly included in Psathyrometra are removed to Athrypsometra gen. n., retained in the Antedonidae. The other genera formerly included in the Zenometrinae are considered incertae sedis in the family Antedonidae pending detailed re-examination. Cladistic analysis using the antedonids, Poliometra prolixa (a former zenometrine) and Florometra serratissima, and the thalassometrid, Oceanometra annandalei, as outgroups produces the following tree: (O. annandalei ((F. serratissima/P. prolixa)(((P. fragilis/P. congesta) P. bigradata) (S. triserialis/Z. columnaris)))).

Résumé [+] [-]Three new species of unstalked crinoids (Echinodermata, Crinoidea) belonging to the comasterid genera Comactinia A. H. Clark, 1909, Capillaster A. H. Clark, 1909 and Cenolia A. H. Clark, 1916 from depths of 73-310 m, are described. Comactinia titan n. sp., from the Philippines and New Caledonia, which bears thicker arms than any other comasterid, is the first representative of its genus recorded outside the tropical western Atlantic. Capillaster squarrosus n. sp., from Vanuatu, resembles C. multiradiatus (Linnaeus, 1758) but has uniquely modified arms. Cenolia amezianeae n. sp., from southern New Caledonia and Vanuatu, resembles its congeners but bears combs on pinnules as far as P-19 (rather than just to P-4 as in other Cenolia), which requires an emendation of the generic diagnosis.

Résumé [+] [-]The unusual bathyal comatulid crinoid genus Atelecrinus is widespread in the Atlantic and tropical Pacific Oceans and currently includes three recognized species. A re-assessment based on examination of new and existing specimens requires establishment of two new genera and five new species, and returns three junior synonyms to species-level status. Paratelecrinus is erected to accommodate Atelecrinus wyvilli PH Carpenter, A. conifer AH Clark, A. cubensis PH Carpenter, P. orthotriremis, new species, P. amenouzume new species, P. laticonulus new species and P. telo new species. Adelatelecrinus is erected to accommodate Atelecrinus sulcatus AH Clark and Adelatelecrinus vallatus new species. Atelecrinus retains A. balanoides PH Carpenter and A. helgae AH Clark, which restricts the genus to the Atlantic. In both Paratelecrinus and Adelatelecrinus, the basals articulate with the centrodorsal via ligament bundles anchored in deep ring-like interradial pits that project into the centrodorsal cavity, whereas in Atelecrinus the centrodorsal rim has shallow interradial concavities and attaches to the basals via a tight junction with no obvious ligament bundles. The spoon-shaped aboral fossa in the basals of Paratelecrinus appears to be unique among articulate crinoids and differs from the smooth fossa found in both Atelecrinus and Adelatelecrinus. New material extends the range of the family to the Indian Ocean. A few species are now known from enough specimens to identify some ontogenetic and distributional variations. Proximal ray morphology varies substantially with size in P. cubensis and P. orthotriremis. A. balanoides generally occurs in deeper water in the Lesser Antilles than in the Bahamas and Strait of Florida, while P. orthotriremis occurs in shallower water in the Lesser Antilles and deeper in the Bahamas.

Résumé [+] [-]A new species in the family Bathycrinidae is described from abyssal depths from the Bahamas. It is referred to the recently established genus Discolocrinus, which formerly comprised a single species D. thieli Mironov, 2008 from the Eastern Pacific. Discolocrinus iselini n. sp. is characterized by large body size, high tegmen with tube-like upper region, extremely elongated IBr1 and IBr2, large knobby processes on primibrachials, and overgrowth of soft tissue on the pinnules, the tissue containing numerous perforated or imperforate ossicles of varying size and form. Differences between Discolocrinus and other bathycrinids may seem to be of taxonomic importance at the family level, but knowledge of the morphology and variability of both species of Discolocrinus is incomplete and, until a richer material becomes available, the genus should remain in family Bathycrinidae. Representatives of five families with xenomorphic stalks were examined to characterize the genera on the basis of number or form of knobby processes. These processes occur in two families with differing external morphology: ten-armed Bathycrinidae and five-armed Bourgueticrinidae. They also occur in the comatulid family Atelecrinidae. This similarity might seem to indicate a close relationship between the three families. However, morphological analysis supports the separation of the families Caledonicrinidae and Septocrinidae from Bathycrinidae despite the fact that they share a xenomorphic stalk and IBr2ax. These conclusions are in agreement with results of recent molecular studies.

Résumé [+] [-]Echinoids are key components of modern marine ecosystems. Despite a remarkable fossil record, the emergence of their crown group is documented by few specimens of unclear affinities, rendering their early history uncertain. The origin of sand dollars, one of its most distinctive clades, is also unclear due to an unstable phylogenetic context. We employ 18 novel genomes and transcriptomes to build a phylogenomic dataset with a near-complete sampling of major lineages. With it, we revise the phylogeny and divergence times of echinoids, and place their history within the broader context of echinoderm evolution. We also introduce the concept of a chronospace – a multidimensional representation of node ages – and use it to explore methodological decisions involved in time calibrating phylogenies. We find the choice of clock model to have the strongest impact on divergence times, while the use of site-heterogeneous models and alternative node prior distributions show minimal effects. The choice of loci has an intermediate impact, affecting mostly deep Paleozoic nodes, for which clock-like genes recover dates more congruent with fossil evidence. Our results reveal that crown group echinoids originated in the Permian and diversified rapidly in the Triassic, despite the relative lack of fossil evidence for this early diversification. We also clarify the relationships between sand dollars and their close relatives and confidently date their origins to the Cretaceous, implying ghost ranges spanning approximately 50 million years, a remarkable discrepancy with their rich fossil record.

Résumé [+] [-]Ophiuroid assemblages were successfully predicted from current museum sample data using presence-only modeling techniques and a multivariate classification on the resulting species occurrence probabilities across the Coral and Tasman Seas (20-37°S, 148-172°E). The classification involves two-stages. The first uses a non-hierarchical clustering technique to reduce the number of data points (map-pixels) to a manageable number that can be analysed in a second stage with a hierarchical classification method. For both steps, the Bray-Curtis similarity statistic is used.

Résumé [+] [-]The large-scale spatial distribution of seafloor fauna is still poorly understood. In particular, the bathyal zone has been identified as the key depth stratum requiring further macro- ecological research [ 1 ], particularly in the Southern Hemi- sphere [ 2 ]. Here we analyze a large biological data set derived from 295 research expeditions, across an equator- to-pole sector of the Indian, Pacific, and Southern oceans, to show that the bathyal ophiuroid fauna is distributed in three broad latitudinal bands and not primarily differentiated by oceanic basins as previously assumed. Adjacent faunas form transitional ecoclines rather than biogeographical breaks. This pattern is similar to that in shallow water despite the order-of-magnitude reduction in the variability of environmental parameters at bathyal depths. A reliable biogeography is fundamental to establishing a representative network of marine reserves across the world’s oceans [1, 3].

Résumé [+] [-]There have been comparatively few large-scale studies on spatial genetic structure of bathyal sea floor fauna, despite the importance of these data to the successful management of the world's oceans.We use a comparative analysis of mitochondrial DNA from five bathyal (200–3500m) species of brittle-stars (Ophiuroidea) to assess phylogeographic structure along an extensive (8000km) longitudinal gradient at temperate latitudes (28–561S) from south-west Australia(113°E) to seamounts east of New Zealand (175°W). We found no evidence of a genetic discontinuity between Australia and New Zealand,either across the temperate Tasman Sea or across the Southern Ocean between the South Tasman Rise and the Macquarie Ridge. However, there were latitudinal phylogeographical breaks between tropical, temperate and polar regions; longitudinal breaks across the eastern Indian Ocean; and a bathymetric break at approximately 1700m. Although there was limited regional structure in the frequency of haplotype distributions within the major clades, and no clade appeared to be strictly panmictic, the regional structure in general was not concordant with a simple isolation-by-distance model. Demographic structure varied with three clades having a simplified haplotype network, low effective population sizes and no evidence of significant population expansion, and two clades having a high diversity of haplotypes, relatively high effective population sizes and signs of recent population expansion. These results are discussed with respect to putative dispersal strategies. We hypothesise that the ‘brooding’ species produce both brooded young and pelagic larvae, allowing for both the maintenance of local populations and long-distance dispersal.

Résumé [+] [-]The deep-seafloor in the tropical Indo-Pacific harbours a rich and diverse benthic fauna with numerous palaeoendemics. Here, we describe a new species, genus and family of brittle-star (Ophiuroidea) from a single eight-armed specimen collected from a depth between 360 and 560 m on Banc Durand, a seamount east of New Caledonia. Leveraging a robust, fossil-calibrated (265 kbp DNA) phylogeny for the Ophiuroidea, we estimate the new lineage diverged from other ophiacanthid families in the Late Triassic or Jurassic (median = 187–178 Myr, 95% CI = 215–143 Myr), a period of elevated diversification for this group. We further report very similar microfossil remains from Early Jurassic (180 Myr) sediments of Normandy, France. The discovery of a new ancient lineage in the relatively well-known Ophiuroidea indicates the importance of ongoing taxonomic research in the deep-sea, an environment increasingly threatened by human activities.

Résumé [+] [-]The genus Asteromorpha Lütken (Echinodermata: Ophiuroidea: Euryalidae: Euryalinae) is revised based on 52 specimens, including six syntypes of Asteromorpha steenstrupi, one syntype of Asteromorpha perplexum (Koehler), one syntype of Asteromorpha koehleri (Döderlein) and the holotype of Astroschema capensis Mortensen. We propose a new combination of Asteroschema capense (Euryalidae: Asteroschematinae) with the genus Asteromorpha. Consequently Asteromorpha includes four species: A. capensis, A. koehleri, A. rousseaui, and A. tenax. These four species are all redescribed. A taxonomic key to the species of the genus Asteromorpha is also provided.

Résumé [+] [-]Previous molecular analysis of the order Euryalida (Echinodermata: Ophiuroidea), has identified three monophyletic families, the Euryalidae, Asteronychidae and Gorgonocephalidae. However, family-level relationships have remained unresolved due to inadequate taxon sampling and insufficient molecular markers. Here, we present a family-level revision of the Euryalida based on sequences from mitochondrial genes (16S rRNA and COI) and a nuclear gene (18S rRNA) from 83 euryalid ophiuroids. The monophyly of the three families, Euryalidae, Asteronychidae and Gorgonocephalidae is confirmed. The Euryalidae and Asteronychidae + Gorgonocephalidae are assigned to superfamilies, the Euryalidea and the Gorgonocephalidea, respectively. Three subclades within the family Gorgonocephalidae are identified and assigned to three subfamilies; Astrotominae includes Astrocrius, Astrohamma and Astrotoma, Astrothamninae (subfamily nov.) includes Astrothamnus and Astrothrombus with Gorgonocephalinae including the remaining genera. Morphological characters are consistent with the newly recognised superfamilies and subfamilies.

Résumé [+] [-]Ophiuroids of the families Ophiacanthidae (46 species) and Hemieuryalidae (2 species) are monographed for the region around New Caledonia in the southwest Pacific Ocean. Ophiohamus nanus n. gen. n. sp. is described in the Ophioplinthacinae. New species are also described in the following genera: Ophiacantha (O. fuscina n. sp., O. richeri n. sp.), Ophioplinthaca (O. amezianeae n. sp.), Ophiomitrella (O. mensa n. sp., O. parviglobosa n. sp.), Ophiothamnus (O. biocal n. sp.) and Ophiurothamnus (O. eleaumei n. sp.). The genus Ophiocyclus is synonymised with Ophiurothamnus, Ophiomelina with Ophiacantha, Toporkovia with Ophiolimna, Ophiomytis with Ophioplinthaca, and Ophiogyptis with Ophiomoeris. Ophiomelina moniliformis (Koehler, 1904) thus becomes a junior homonym of Ophiacantha moniliformis Lütken & Mortensen, 1899 and the replacement name Ophiacantha renekoehleri n. nom. is proposed. In addition there are 37 new species-level synonymies and 19 other new genus-species combinations. A key is provided for all genera and all tropical Indo-West Pacific species of the Ophiacanthidae. The results show that the biogeographical relationship of the ophiacanthid fauna of New Caledonia is with the tropical Indo-Pacific. Less than ten percent of the fauna is shared with Southern Australia and fifteen percent with New Zealand. More broadly, there appears to be a single ophiacanthid fauna at upper to middle slope depths (200-2500 m) across the Indo-West Pacific from Africa to Hawaii, with limited east-west differentiation. This fauna grades into distinct temperate bathyal faunas near South Africa, China/Japan and Australia/New Zealand, until there is an almost complete changeover of species by 45° latitude in both hemispheres.

Marine Biodiversity 43(4): 333-339. DOI:10.1007/s12526-013-0160-9
Résumé [+] [-]Ophiodaphne scripta (Koehler, 1904) is an amphiurid brittle star exhibiting an unusual form of conspicuous sexual dimorphism and epibiosis. The males are much smaller and exist as epibionts on the larger female. These male–female pairs, attached mouth to-mouth, are in turn epibionts on cake urchins such as Echinodiscus auritus Leske, 1778, attaching themselves via the aboral side of the female. In this paper, Ophiodaphne scripta (Koehler, 1904) is reported from off the southern Indian peninsula for the first time, extending the range of this species eastwards. The distribution of this species is discussed in conjunction with that of the only other species in this genus, Ophiodaphne formata (Koehler, 1905), which also exhibits similar sexual dimorphism and epibiotic behavior. A detailed description of the specimens from India is provided, along with adaptations to their peculiar lifestyle. In addition, a brief historical review of the systematics of the genus Ophiodaphne Koehler, 1930 is presented, pointing out some discrepancies which persist, despite numerous revisions.

Fixed, free, and fixed: The fickle phylogeny of extant Crinoidea (Echinodermata) and their Permian–Triassic origin. Molecular Phylogenetics and Evolution 66(1): 161-181. DOI:10.1016/j.ympev.2012.09.018
Résumé [+] [-]Although the status of Crinoidea (sea lilies and featherstars) as sister group to all other living echinoderms is well-established, relationships among crinoids, particularly extant forms, are debated. All living species are currently placed in Articulata, which is generally accepted as the only crinoid group to survive the Permian–Triassic extinction event. Recent classifications have recognized five major extant taxa: Isocrinida, Hyocrinida, Bourgueticrinina, Comatulidina and Cyrtocrinida, plus several smaller groups with uncertain taxonomic status, e.g., Guillecrinus, Proisocrinus and Caledonicrinus. Here we infer the phylogeny of extant Crinoidea using three mitochondrial genes and two nuclear genes from 59 crinoid terminals that span the majority of extant crinoid diversity. Although there is poor support for some of the more basal nodes, and some tree topologies varied with the data used and mode of analysis, we obtain several robust results. Cyrtocrinida, Hyocrinida, Isocrinida are all recovered as clades, but two stalked crinoid groups, Bourgueticrinina and Guillecrinina, nest among the featherstars, lending support to an argument that they are paedomorphic forms. Hence, they are reduced to families within Comatulida. Proisocrinus is clearly shown to be part of Isocrinida, and Caledonicrinus may not be a bourgueticrinid. Among comatulids, tree topologies show little congruence with current taxonomy, indicating that much systematic revision is required. Relaxed molecular clock analyses with eight fossil calibration points recover Articulata with a median date to the most recent common ancestor at 231–252 mya in the Middle to Upper Triassic. These analyses tend to support the hypothesis that the group is a radiation from a small clade that passed through the Permian–Triassic extinction event rather than several lineages that survived. Our tree topologies show various scenarios for the evolution of stalks and cirri in Articulata, so it is clear that further data and taxon sampling are needed to recover a more robust phylogeny of the group.

Résumé [+] [-]The MUSORSTOM Expedition has gathered stalked Crinoids (family: Isocrinidae) belonging to the two genera Metacrinus and Saracrinus. Four species are described here, M. musorstomae is a new one. The validity of the genus Saracrinus is confirmed. The organization of the skeleton is analysed. It shows some aspects of the evolution of the Isocrinidae. Metacrinus and Saracrinus present several primitive characteristics. The study of the MUSORSTOM specimens permits a review of our knowledge about recent and fossil Isocrinidae. The recent representatives of this family are more hightly diversified than the fossil one. It becomes apparent that Metacrinus and Saracrinus are two young taxa at the outset of their adaptative radiation.

Résumé [+] [-]Two new species of hyocrinid stalked crinoids from deep waters of the Pacific Ocean are described. Thalassocrinus alvinae n. sp. was collected on the Gorda Ridge and represents the first record of the genus from the Eastern Pacific. Thalassocrinus mironovi n. sp. was found on the bathyal slope off New Caledonia (southwester Pacific). A short revision of the genus Thalassocrinus is given and affinities between the four known species are discussed.

Roux M., Eléaume M., Hemery L.G. & Améziane N. 2013. When morphology meets molecular data in crinoid phylogeny: a challenge. Cahiers de Biologie marine 54: 541-548
Résumé [+] [-]The extant crinoid fauna results from more than 485 Myr of evolution (from Early Ordovician). Detailed morphological studies on extant crinoids document large intraspecific variations, strong changes through ontogeny with various mosaics of heterochronic development, and adaptive characters which depend on environment, mainly hydrodynamics and food supply. The importance of paedomorphy and morphological convergences (homoplasies) in crinoid evolution is confirmed by studies using DNA markers, and makes difficult the use of cladistic methods of phylogenetic reconstructions. Many clades of extant crinoids based on external skeleton morphology are polyphyletic. Using the hyocrinids and a recent extensive molecular phylogeny of the extant crinoids, we show that the molecular approach, when coupled with detailed ontogenetic analyses on a large sample of specimens and taxa, may help understand the evolutionnary trends within a given group of organisms. Purely molecular or phenotypic analyses produce contrasting results because these analyses work at scales that are separated by a strong gap. We propose a deep reappraisal of the relationships between extant and fossil taxa using the concept of onto phylogeny which rejects the classical separation between ontogeny and phylogeny and argues that natural selection acts at every level of integration of the organism from DNA, cells, tissues, to the individuals and populations.

Résumé [+] [-]Tormocrinus, have yielded arguments for a revision of the taxonomy and interrelationships of extant and fossil taxa in the family Bourgueticrinidae. Conocrinus (= Tormocrinus), as here interpreted, includes six Eocene species: C. thorenti, C. archiaci, C. cahuzaci n. sp., C. duperrieri, C. cf. suessi and C. veronensis. Numerous extinct species previously attributed to Conocrinus or Democrinus are here transferred to two new genera which first occur in the lower Paleocene: Paraconocrinus n. gen. (type species: P. pyriformis) and Pseudoconocrinus n. gen. (type species: P. doncieuxi). Aboral cups from the “Rocher du Goulet” (Biarritz) are here assigned to Paraconocrinus pellati n. gen., n. sp., while the Danian species Democrinus maximus is transferred to Pseudoconocrinus n. gen. A new genus, Cherbonniericrinus, is created to accommodate a single extant species, Ch. cherbonnieri, previously attributed to Conocrinus, while the extant genus Rhizocrinus, closely related to Democrinus, is resurrected. Conocrinus and closely related genera are derived from a bourgueticrinine lineage the first record of which is from the lower Campanian, with the new genus Carstenicrinus. These are all attributed to the family Rhizocrinidae which is here considered distinct from the family Bourgueticrinidae. Rhizocrinids rapidly diversified immediately after the Cretaceous-Paleogene (K/Pg) event. Cretaceous taxa previously placed within the family Bourgueticrinidae now appear to be polyphyletic. Some of them do not belong to Bourgueticrinina, such as those of the Dunnicrinus lineage. Interrelationships of Rhizocrinidae and other post-Palaeozoic families having a xenomorphic stalk are discussed.

Résumé [+] [-]The 2009 expedition with the research vessel Miriky sampled the sublittoral and bathyal waters of the northern Mozambique Channel. This exploration campaign resulted in a small, but very diverse collection of holothuroids comprising 174 specimens representing 31 species, 18 genera, 10 families and 5 orders. Of these species, many were hitherto unknown for Madagascar or even for the Indian Ocean, and six, Bathyplotes aymeric sp. nov., Holothuria (Cystipus) yann sp. nov., Holothuria (Stauropora) bo sp. nov., Holothuria (Metriatyla) alex sp. nov., Holothuria (Theelothuria) cyrielle sp.nov., Molpadia thandari sp. nov., are new to science. Molpadia lenticulum (Cherbonnier & Féral, 1981) is a new combination. This contribution provides an illustrated and annotated overview of the poorly known, highly biodiverse, sublittoral and bathyal sea cucumber fauna of the northern Mozambique Channel. Our findings demonstrate how ignorant we are about the poorly explored habitats of our planet and therefore stress the urgent need for more explorations to such regions.

Résumé [+] [-]The composition and évolution of the subgenus Oligotrochus [genus Myriotrochus (Myriotrochidae, Apodida, Holothurioidea)] are discussed. In addition to the type species of the subgenus, M. (O.) vitreus (M. Sars, 1866), two other species are transferred to this subgenus: M. (O.) clarki Gage et Billett, 1986 and M. (O.) bathybius H. L. Clark, 1920. Moreover, two new species are described: M. (O.) rotulus n.sp. From the West Galicia coast, Spain, Northeast Atlantic and M. (O.) neocaledonicus n.sp. From the Loyalty Islands Basin, New Caledonia, Pacific. M. (O.) rotulus n.sp. Is characterized by wheels with "fused spokes". The spokes in thèse wheels are swollen and sometimes are fused, leaving small oval holes near the hub. The number of thèse holes corresponds to the number of fused pairs of spokes and ranges from two up to the total number of spokes. Thèse wheels usually have less hub perforations than spokes, because not ail of the spokes are fused. The latter character and a smaller size of the wheels clearly differ M. rotulus from M. bathybius and M. neocaledonicus, which have wheels with hub penetrated by a complete circle of perforations. M. (O.) neocaledonicus n.sp. Is characterized by wheels wirh perforated hub which closely resemble wheels of M. (O.) bathybius. The new species differs from M. (O.) bathybius in having a smaller length of hub perforations and by the shape of thèse perforations (triangular or ovoid-triangular in M. (O.) neocaledonicus, and ovoid in M. (O.) bathybius). An identification key for the species belonging to the subgenus Oligotrochus is given.

Proceedings of the 10th International Conference, Dunedin, 31 January-4 February 2000:317-322, ISBN:90-265-1868-4
Résumé [+] [-]In 1999, several hundred specimens of a small brittle star were collected from the ventral side of a species of spatangoid sea urchins from about 260-650 m depth in the South Pacific near Fiji. Disc diameters of these ophiuroids varied between 1.3 and ca. 3 mm. They exhibit a morphological sexual dimorphism, with males having an enlarged First ventral arm spine. The species was identified as Amphiodia crassa (Koehler, 1904), but discrepancies between the drawings of the original type, later descriptions, and the new individuals led to an investigation of the actual status of this species. Unfortunately, the type has been lost, but evidence suggests that the individuals from Fiji are a different species for which a new name is suggested.

Résumé [+] [-]Recent efforts to reconstruct the phylogeny of brittle stars (ophiuroids) have shown the need for more objective and reproducible data collection methods than the traditional visual examination and verbal description of morphological characters. Complex skeletal structures may be better understood in three dimensions than in two dimensions obtained from techniques like scanning electron microscopy (SEM). We test this hypothesis using three types of three-dimensional tomographic imaging methods—lab-based micro-CT, X-ray microscopy and synchrotron-based tomography—to examine the morphology of ophiuroid arms, and compare them with twodimensional data obtained from SEM. We describe the advantages and disadvantages of each instrument and set of parameters in terms of the ease and efficiency of data collection for morphometric analyses. We present new morphological observations obtained by digital sectioning of three-dimensional images that could not be achieved with SEM. Overall, our findings suggest that three-dimensional imaging has a high potential to address the gaps in knowledge of the internal ophiuroid skeleton, which will be pivotal to providing morphological characters that will aid in phylogenetic reconstructions.

Résumé [+] [-]Comatulidae Fleming, 1828 (previously, and incorrectly, Comasteridae A.H. Clark, 1908a), is a group of feather star crinoids currently divided into four accepted subfamilies, 21 genera and approximately 95 nominal species. Comatulidae is the most commonly-encountered and species-rich crinoid group on shallow tropical coral reefs, particularly in the Indo-western Pacific region (IWP). We conducted a molecular phylogenetic analysis of the group with concatenated data from up to seven genes for 43 nominal species spanning 17 genera and all subfamilies. Basal nodes returned low support, but maximum likelihood, maximum parsimony, and Bayesian analyses were largely congruent, permitting an evaluation of current taxonomy and analysis of morphological character transformations. Two of the four current subfamilies were paraphyletic, whereas 15 of the 17 included genera returned as monophyletic. We provide a new classification with two subfamilies, Comatulinae and Comatellinae n. subfamily Summers, Messing, & Rouse, the former containing five tribes. We revised membership of analyzed genera to make them all clades and erected Anneissia n. gen. Summers, Messing, & Rouse. Transformation analyses for morphological features generally used in feather star classification (e.g., ray branching patterns, articulations) and those specifically for Comatulidae (e.g., comb pinnule form, mouth placement) were labile with considerable homoplasy. These traditional characters, in combination, allow for generic diagnoses, but in most cases we did not recover apomorphies for subfamilies, tribes, and genera. New morphological characters that will be informative for crinoid taxonomy and identification are still needed. DNA sequence data currently provides the most reliable method of identification to the species-level for many taxa of Comatulidae.

Résumé [+] [-]The gastropod family Eulimidae has attracted considerable attention as one of the most diverse groups of parasitic molluscs in terms of number of species and ranges of body plans and parasitic strategies. However, the phylogenetic position of the family has not been established within the Hypsogastropoda and this has hampered the inference of ancestral states in the evolution of the morphology and parasitic strategies. Here we present Bayesian and maximum likelihood phylograms of Hypsogastropoda based on nuclear and mitochondrial loci (18S and 28S rRNA, Histone H3, COI and 16S rRNA) and a better taxonomic sampling than in previous molecular analyses, to determine the position of Eulimidae. The resulting trees suggest Vanikoridae as the sister group of Eulimidae; the two families are collectively placed in the newly redefined superfamily Vanikoroidea, with Truncatelloidea and (potentially paraphyletic) Rissooidea as closest relatives. Vanikorids are protandrous hermaphrodites as are many eulimids and are essentially carnivorous, differing from the mostly gonochoristic and herbivorous/detritivorous Truncatelloidea and Rissooidea. The mode of feeding may have a phylogenetic signal also within Eulimidae, where radula-less species constitute a robust clade. Other new findings include a close affinity of the submarine-cave Pickworthiidae to Cerithioidea and a terminal position of Nystiellidae within the paraphyletic Epitoniidae.

Résumé [+] [-]The purpose of the BIOCAL, MUSORSTOM 4 and BIOGEOCAL océanographie cruises was to study the nature and the affinities of the deep-sea fauna of New Caledonia. This area has been until then poorly prospected and its echinoderm fauna is almost unknown. Among the Ophiuridae collected during these two cruises, a first group of 10 species is studied. Five of them are new for science : the subfamilial status of the genus Ophiophyllum Lyman and the affinities of the genera Anihophiura Fasmer and Aspidophiura Matsumoto are discussed. The species belonging to the genera Ophiophycis. Ophiopyrgus, Aspidophiura. Anthophiura. Ophiotypa and Perlophiura. Very small and showing a rudimentary external morphology, are considered as progenetic. These present collects show once more the frequency of these progenetic forms at bathyal and abyssal levels.

Résumé [+] [-]Secondary metabolites often play an important role in the adaptation of organisms to their environment. However, little is known about the secondary metabolites of ancient organisms and their evolutionary history. Chemical analysis of exceptionally well-preserved colored fossil crinoids andmodern crinoids from the deep sea suggests that bioactive polycyclic quinones related to hypericin were, and still are, globally widespread in post-Paleozoic crinoids. The discovery of hypericinoid pigments both in fossil and in presentday representatives of the order Isocrinida indicates that the pigments remained almost unchanged since the Mesozoic, also suggesting that the original color of hypericinoid-containing ancient crinoids may have been analogous to that of their modern relatives. The persistent and widespread occurrence, spatially as well as taxonomically, of hypericinoid pigments in various orders during the adaptive radiation of post-Paleozoic crinoids suggests a general functional importance of the pigments, contributing to the evolutionary success of the Crinoidea.

Résumé [+] [-]This publication is the third in a series of accounts on large collections of Plumularioidea McCrady, 1859 (Cnidaria, Hydrozoa, Hydroidolina) obtained during several French expeditions to the Philippines region, Vanuatu, New Caledonia, Fiji, and the Marquesas Islands. Additional material from Mozambique was also examined and is discussed. A total of 17 species, belonging to the families Kirchenpaueriidae Stechow, 1921 (two species) and Plumulariidae McCrady, 1859 (15 species), are scrutinized and illustrated in the present report. Three new species of the genus Plumularia Lamarck, 1816 are described (Plumularia bathyale n. sp., Plumularia contraria n. sp., Plumularia pseudocontraria n. sp.). The name Plumularia milsteinae n. nom., is proposed for Plumularia spiralis Milstein 1976, a permanently invalid junior homonym of Plumularia spiralis Billard, 1911. Polyplumaria kossowskae (Billard, 1911) is recorded for the first time since its original description. Two species of Plumularia are identified only to the genus level. Type materials of Plumularia habereri Stechow, 1909 and Dentitheca hertwigi Stechow, 1909, and the syntypes of all varieties of Plumularia habereri described by Billard (1913), have also been examined.

Résumé [+] [-]One new genus (Schizoplumularia) and three new species (Schizoplumularia vervoorti, S. geniculata and S. elegans) of plumulariids are recognized and described from large collections of plumularioid hydroids collected in New Caledonia and vicinity during several French expeditions. During taxonomic studies of these hydroids, colonies were compared with type material of Plumularia insignis Allman, 1883 and several other similar species-group taxa. As a result, three of the latter (P. flabellum Allman, 1883, P. conjuncta Billard, 1913, and P. billardi nom. nov.) are recognized as valid in addition to P. insignis. The binomen P. billardi is a replacement name for P. insignis var. gracilis Billard, 1913. In being elevated to the rank of species in this work, it becomes an invalid junior primary homonym of several others having the same name.

Résumé [+] [-]Among specimens of sea anemones collected from the tropical western Pacific on cruises under the auspices of the Institut de Recherche pour le Développement (IRD) and the Muséum national d’Histoire naturelle, Paris, are some we identify as Exocoelactis actinostoloides (Wassilieff, 1908). We synonymize under this name the species described as Cymbactis maxima Wassilieff, 1908, and Exocoelactis valdiviae Carlgren, 1928. The first two were described from one specimen each, collected at unspecified depths of Sagami Bay, Japan; the latter was based on five specimens reportedly collected off the coast of East Africa at depths of 741 to 823 m. We examined 23 specimens collected in New Caledonia, the Philippines, and Palau from depths of 175 to 480 m. Thus, we extend the geographical and bathymetric range of this species. These specimens allowed us to resolve discrepancies in the definition of the genus Exocoelactis concerning completeness and sterility of the mesenteries: the stronger partner of the mesenterial pairs may be complete and may be sterile.

Résumé [+] [-]Novel micromorphological characters in combination with molecular studies have led to an extensive revision of the taxonomy and systematics of scleractinian corals. In the present work, we investigate the macro- and micromorphology and the phylogenetic position of the genera Australomussa and Parascolymia, two monotypic genera ascribed to the family Lobophylliidae. The molecular phylogeny of both genera was addressed using three markers, the partial mitochondrial COI gene and the nuclear histone H3 and the ribosomal ITS region. Based on molecular data, Australomussa and Parascolymia belong to the Lobophylliidae and they cluster together with the genera Lobophyllia and Symphyllia within the same clade. While A. rowleyensis and P. vitiensis are closely related based on the three gene regions examined, their macro and micromorphology suggest that these species are distinct, differing in several characters, such as continuity and thickness of the costosepta, the number of septa, septal tooth height, spacing, and shape, and the distribution and shape of granules. Thus, we revise the taxonomic status of the genus Australomussa as a junior synonym of Parascolymia.

Résumé [+] [-]Five new species of the family Isididae from New Caledonian waters are described together with comparative material from elsewhere in the western Pacific Ocean. By comparison with specimens from Australia, the Philippines, Taiwan and the Ryukyu Islands, the population of Isis in New Caledonia is considered to be within the range of variation of Isis hippuris Linnaeus. Mopsea bargibanti, M. laboutei and M. provocatoris are described as new to science and compared with M. whiteleggei from Australia. The genus Acanthoisis Studer and Wright, previously treated as a synonym of Mopsea Lamouroux, is restored to validity as a distinct genus. Acanthoisis richerdeforgesi and A. dhondtae are described as new and compared with the type-species of the genus, A. flabellum Wright and Studer, which is considered as a probable senior subjective synonym of Mopsea simplex Tixier-Durivault. The genus Sclerisis Studer, previously treated as a questionable synonym of Primnoisis Studer and Wright, is restored to validity and a new species, Sclerisis macquariana, is described from south of New Zealand. A revised key to the genera of the family Isididae and a key to the genera and species known or expected in New Caledonian waters are presented.

Résumé [+] [-]The major reef-building coral genus Acropora has never been recorded, living or fossil, from the Marquesas Islands in the central Pacific Ocean, which are characterized by limited modern reef formations. During the "Musorstom 9" cruise in 1997, investigations of marine platforms representing drowned reef systems revealed for the first time the presence of two Acropora species as fossils at seven Marquesas islands. The predominant species was Acropora valida, which was widespread in the archipelago and dated between 7.4 and 48.6 ka, providing evidence of an earlier Pacific distribution pattern broader than previously observed. It is proposed that disappearance of Acropora after 7.4 ka was linked to climatic events probably ENSO events controlling the distribution of corals and coral reefs in the eastern Pacific without excluding alternatively the effects of an increase in sea-level rise.

Résumé [+] [-]Fifty-three species of ahermatypic Scleractinia—about half of the Philippine ahermatypic fauna—belonging to four families and one subfamily are described and illustrated. Five additional species found in adjacent waters just north of the Philippines are also included in the faunistic revision. In order to better evaluate the genus Leptopenus, L. antarcticus, from Antarctica, is also included in this revision as a new species, making a total of 59 species revised. Concurrent with the species revision, higher-level taxa were reanalyzed and revised, resulting in the description of four new genera: Endocyathopora, Thrypticotrochus, Truncatoguynia, and Truncatoflabellum and 17 new species; the formation of 13 new species combinations; and the establishment of two new subgeneric ranks: Fungiacyathus (Bathyactis) and Flabellum (Ulocyathus). To help stabilize the nomenclature of taxonomically confusing species, neotypes were designated for two species: Flabellum (= Truncatoflabellum) cumingii and Flabellum (= Truncatoflabellum) candeanum; and lectotypes were chosen for four other species: Bathyactis (= Fungiacyathus) sibogae, Flabellum pavoninum, Flabellum distinctum, and Flabellum patens. Approximately 4400 specimens were examined from 178 stations throughout the Philippines, as well as most of the previously reported specimens from this area. A historical resume is given of previous literature on ahermatypic Scleractinia in the Philippine Islands. Character tables or keys are provided for the genera of Micrabaciidae, Turbinoliinae, Guyniidae, and Flabellidae, and character tables are provided for the Philippine species of Fungiacyathus, Stephanophyllia, Flabellum (Flabellum), and Truncatoflabellum. The Philippine Islands and Indonesia, especially the Sulu Sea, are considered to be at or near the center of ahermatypic species diversity and thus represent the most diverse ahermatypic fauna in the world. East and west of the Philippines the number of species held in common falls rapidly, but relatively high percentages of shared species are found to the north: 30%-32% for the South China Sea off Hong Kong, and 36%-38% for off Japan. The highest number of shared species, however, is with Indonesia (25-27 species, 47%-51%), with which the Philippines probably forms a zoogeographic unit Of the 53 species reported from the Philippines, 27 are new records for this island group.

Cairns S.D. 1998. Azooxanthellate Scleractinia (Cnidaria: Anthozoa) of Western Australia. Records of the Western Australian Museum 18: 361-417
Résumé [+] [-]One hundred five species of azooxanthellate Scleractinia are known from Western Australia. Seventy of these species are reported herein as new records for Western Australia, 57 of which are also new to Australia. Eleven new species are described. The study was based on an examination of approximately 1725 specimens from 333 stations, which resulted in additional records of 98 of the 105 known species. New material was examined from six museums, as well as the historical material of Folkeson (1919) deposited at the Swedish Museum of Natural History. A majority (69/105 species) of the azooxanthellate species known from Western Australia occur in the tropical region of the Northern Australian Tropical Province (bordered to the south by the Houtrnan Abrolhos Islands and Port Gregory), which can be considered as a southern extension of the larger Indo-West Pacific tropical realm. Nine species are endemic to this region, and the highest latitudinal attrition of species occurs between Cape Jaubert and the Dampier Archipelago. Another 20 species, also known from tropical regions, extend to varying degrees into the Southern Australian Warm Temperate Province. Twelve species are restricted to warm temperate waters of the Southern Australian Warm Temperate Region, most of these species being relatively shallow in depth distribution. A majority of species (53) occur at depths shallower than 200 m, 46 occur exclusively deeper than 200 m (to 1011 m), and 6 species cross the 200 m isobath. Commensal relationships (galls) with ascothoracidan crustaceans were found with two corals hosts (Madrepora oculata and Deltocyathus magnifieus), and with acrothoracican cirripedes (thecal borings) with six coral hosts: Flabellum politum, Tnmcatoflabellum folkesoni, T. formosum, T. australiensis, Javania lamprotichum, and Dendrophyllia alcocki.

Résumé [+] [-]A total of 134 Recent species of azooxanthellate Scleractinia are reported from the Vanuatu (116 species) and Wallis and Futuna (83 species) Archipelagos, all but one being new records for this region of the tropical central Pacific. The newly reported specimens originate primarily from the MUSORSTOM 7 and 8 expeditions, including approximately 4400 specimens from 227 stations, most of these stations from deeper than 100 m. Sixteen new species and one new subspecies are described, and two new combinations are proposed: Asterosmilia gigas and Javania fusca. Tables of comparison are provided for the Indo-Pacific species of Fungiacyathus (Fungiacyathus)-, the Recent Trocliocyalhus (Aplocyathus)\ all species oi Aulocyathus\ all species of spined Deltocyathus\ and the Recent species and subspecies of Antheiniphyllia. To facilitate comparisons of species among these taxa, three additional species having distributions other than the Vanuatu/Wallis and Futuna region are described as new: Deltocyathus corrugalus, Antheiniphyllia inultidentata, and A. inacrolobata. The distribution and bathymétrie ranges of the 134 species known from the Vanuatu/Wallis and Futuna region are tabulated. Within the tropical central Pacific these corals show a strong affinity with those from the ridges and islands north of New Zealand (56 species) and a lesser relationship with the Hawaiian Island fauna (24 species). Other regions in the central Pacific are too poorly known for comparison. Beyond the tropical central Pacific, the Vanuatu/Wallis and Futuna fauna is part of the larger Indo-Polynesian province, sharing 95 (71%) of its species with the tropical western Pacific and 62 species (46%) with the Indian Ocean. Only seven species are found in common with the tropical eastern Pacific and 11 with the Atlantic Ocean. Finally, 43 species from the Vanuatu/Wallis and Futuna Archipelagos are also known from temperate Japan (exclusive of the Ryukyu Islands) and 32 from temperate New Zealand and southern Australia. Examples of commensal/parasitic relationships are reported to occur with petrarcid ascothoracican crustaceans (2 coral hosts) and acrothoracican cirripede crustaceans (8 hosts). The shells of the gastropod Xenophora ("carrier shells") were found to be effective collectors of deep-water corals; a total of 19 coral species were found incorporated into the shells, including three species that were found only on these shells and another five species that were otherwise very rarely collected by conventional means.

Cairns S.D. 2007. Deep-water corals: an overview with special reference to diversity and distribution of deep-water scleractinian corals. Bulletin of marine Science 81(3): 311–322
Résumé [+] [-]The polyphyletic term coral is defined as those Cnidaria having continuous or discontinuous calcium carbonate or horn-like skeletal elements. So defined, the group consists of seven taxa (Scleractinia, Antipatharia, Octocorallia, Stylasteridae, and Milleporidae, two zoanthids, and three calcified hydractiniids) constituting about 5080 species, 66% of which occur in water deeper than 50 m, i.e., deep water as defined in this paper. Although the number of newly described species of deepwater scleractinian corals appears to be increasing at an exponential rate, it is suggested that this rate will plateau in the near future. The majority of azooxanthellate Scleractinia is solitary in form, firmly attached to a substrate, most abundant at 200–1000 m, and consist of caryophylliids. Literature helpful for the identification of deep-water Scleractinia is listed according to 16 geographic regions of the world. A species diversity contour map is presented for the azooxanthellate scleractinian species, showing centers of high diversity in the Philippine region, the western Atlantic Antilles, and the northwest Indian Ocean, and is remarkably similar to high diversity regions for shallow-water zooxanthellate Scleractinia. As suggested for shallow-water corals, the cause for the high diversity of deep-water scleractinian diversity is thought to be the result of the availability of large contiguous stable substrate, in the case of deep-water corals at depths of 200–1000 m (the area effect), whereas regions of low biodiversity appear to be correlated with a shallow depth of the aragonite saturation horizon.

Cairns S.D. & Bayer F.M. 2009. A Generic Revision and Phylogenetic Analysis of the Primnoidae (Cnidaria: Octocorallia). Smithsonian Contribution to Zoology 629: 1-87
Résumé [+] [-]Primnoidae consists of 36 genera, 7 subgenera, and 233 valid species, making it the fourth largest octocorallian family. Species occur in all ocean basins, especially the Antarctic, at depths of 8–5850 m, making primnoids the deepest-living gorgonacean octocorals. Primnoids are common and characteristic of seamounts and deepwater coral banks, often providing habitat for other marine life and serving as proxies for isotopic analyses to determine paleotemperatures. Diagnoses of the primnoid genera and subgenera are based primarily on their type species, and specimens are illustrated by means of scanning electron microscopy, often using stereo images to allow better appreciation of the topology and interconnection of the calycular sclerites. A history of the higher classification of the family is given. Each genus is briefly discussed, and also included are a synonymy of pertinent references, a summary of the geographic and bathymetric ranges, and the deposition of the type specimens of the type species. Four new genera, two new subgenera, one new species, and seven new combinations are proposed. A list of the 233 valid species and the 14 infraspecifi c taxa is provided along with the purported junior synonyms. An indented dichotomous key is provided for identification of the genera and subgenera. Phylogenetic analysis of the genera and subgenera was performed using 27 morphological characters comprising 94 character states. The cladogram does not consistently support the conventional arrangement of genera into fi ve subfamilies, thus this classification is not followed herein. The origin of the primnoids is inferred to be from an ancestor living in the Antarctic.

Résumé [+] [-]The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus fiavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral dise had four lobes (I quadrilobatus) or eight (Synactinernus Flavus) - we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number.

Résumé [+] [-]Forty-three species of sertulariid hydroids (Cnidaria: Hydrozoa: Sertulariidae), collected from the tropical western Pacific (Taiwan, Philippines, New Caledonia, French Polynesia, Vanuatu, Fiji, Tonga, Solomon Islands) during various expeditions of the French Tropical Deep-Sea Benthos program, are discussed. Of these, nine are new to science: Gonaxia nova sp. nov., G. plumularioides sp. nov., Sertularella folliformis sp. nov., Se. plicata sp. nov., Se. pseudocatena sp. nov., Se. splendida sp. nov., Se. tronconica sp. nov., Se. tubulosa sp. nov., and Symplectoscyphus paucicatillus sp. nov. The subspecies Symplectoscyphus johnstoni (Gray, 1843) tropicus Vervoort, 1993 is raised to species but, in order to avoid the secondary homonymy with Sy. tropicus (Hartlaub, 1901), the replacement name, Sy. fasciculatus nom. nov., is introduced. The male and female gonothecae of Diphasia cristata Billard, 1920, the male gonothecae of Gonaxia elegans Vervoort, 1993, as well as the female gonothecae of Salacia macer Vervoort & Watson, 2003, are described for the first time. Additional notes on the morphology of several other species are provided. All taxa are illustrated, in most cases using figures drawn at the same scale, so as to highlight the differences between related species.

Résumé [+] [-]Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp. nov., Synthecium rectangulatum Galea, sp. nov., Diphasia alternata Galea, sp. nov., Dynamena opposita Galea, sp. nov., Hydrallmania clavaformis Galea, sp. nov., Symplectoscyphus acutustriatus Galea, sp. nov., Symplectoscyphus elongatulus Galea, sp. nov. and Zygophylax niger Galea, sp. nov. The male and female gonothecae of Caledoniana decussata Galea, 2015, the female gonothecae of Caledoniana microgona Galea, 2015, as well as the gonothecae of both sexes of Solenoscyphus striatus Galea, 2015 are described for the first time. The systematic position of the genera Solenoscyphus Galea, 2015 and Caledoniana Galea, 2015 is discussed on both morphological and molecular grounds, and both are confidently placed within the family Staurothecidae Maronna et al., 2016. In light of the molecular data, the genera Billardia Totton, 1930 and Dictyocladium Allman, 1888 are assigned to the families Syntheciidae Marktanner-Turneretscher, 1890 and Symplectoscyphidae Maronna et al., 2016, respectively. The previously undescribed gonothecae of Hincksella neocaledonica Galea, 2015, and the male gonothecae of Sertularella tronconica Galea, 2016, were found. Thyroscyphus scorpioides Vervoort, 1993, a peculiar hydroid with putative stem nematothecae, is redescribed and assigned to the new genus Tuberocaulus Galea, gen. nov. Noteworthy new records from the study area are: Tasmanaria edentula (Bale, 1924), Hincksella sibogae Billard, 1918, Dictyocladium reticulatum (Kirchenpauer, 1884), Salacia sinuosa (Bale, 1888) and Billardia hyalina Vervoort & Watson, 2003. Most species are illustrated to facilitate their identification, and the morphology of the new ones is compared to that of their related congeners.

Two new genera and four new species are described, viz, Actinopluma mirifica Galea gen. et sp. nov., provisionally assigned to the family Kirchenpaueriidae Stechow, 1921, Schizoplumularia helicoidalis sp. nov., belonging to the Plumulariidae McCrady, 1859, and Corhiza patula Galea sp. nov. and Thamnopteros uniserius Galea gen. et sp. nov., both placed in the family Halopterididae Millard, 1962. The gonotheca and the medusoid gonophore of Plumularia contraria Ansín Agís et al., 2014 are described for the first time, allowing a genus transfer to Dentitheca Stechow, 1919, as D. contraria comb. nov. Plumularia conjuncta Billard, 1913, known earlier from a minute portion of colony, is redescribed based on a complete, though infertile, specimen. Similarly, complete specimens corresponding to the hydroid previously referred to as Antennella megatheca Ansín Agís et al., 2009 are documented, allowing a provisional reallocation to Corhiza Millard, 1962 and a description of its so far unknown gonothecae. Fertile material assignable to the poorly-known Monostaechas fisheri Nutting, 1905 allows the recognition of this hydroid as a valid species, distinct from M. quadridens (McCrady, 1859). Most taxa are illustrated to validate the reliability of their identifications. Finally, phylogenetic reconstructions of the families Aglaopheniidae, Plumulariidae, and Halopterididae, based on the 16S rRNA, allowed a first genetic characterization of some of the species dealt with in this work.

Galea H.R., Di camillo C.G. & Maggioni D. 2021. An integrative study of Callicarpa gracilis Fewkes, 1881 and Aglaophenia trifida L. Agassiz, 1862, with notes on some hydroids (Cnidaria: Hydrozoa) from French Guiana. Zootaxa 4926(3): 301-341. DOI:10.11646/zootaxa.4926.3.1
Résumé [+] [-]Among the thecate hydroids brought back by the Proteus-Guyane 2017 expedition of the Muséum national d’histoire naturelle of Paris, France, from French Guiana, two interesting species are reported upon. The plumulariid Callicarpa gracilis Fewkes, 1881, known so far from the type specimen only, is comprehensively redescribed 140 years after its original description. It adopts two different morphotypes with respect to both its tropho- and gonosome, forming either simple or ramified colonies, with either structurally-complex or rudimentary phylactocarps, respectively. Taxonomic notes on the genera Callicarpa Fewkes, 1881 and Hippurella Allman, 1877 are provided in light of their intricate history of origin and fate, together with the provisional resurrection of Antomma Stechow, 1919, as an allied genus of the former. The aglaopheniid Aglaophenia trifida L. Agassiz, 1862, whose gonosome was only partly documented to date, is redescribed thoroughly based on specimens bearing male and female corbulae. Scanning electron microscopy and molecular data were also used to document both species. A checklist of the thecate hydroids from French Guiana gathered during Proteus-Guyane 2017 and Guyane 2014 expeditions is provided as an appendix, together with brief notes on some species. Not dealing with the present study, but taking advantage of it, a new name, Antennella billardi Galea, nom. nov., is proposed as a replacement name for Plumularia balei Billard, 1911, which is a permanently invalid junior primary homonym of P. balei Bartlett, 1907.

Galea H.R. & Maggioni D. 2021. An integrative study of some species of Gonaxia Vervoort, 1993 from off New Caledonia, with the establishment of Gonaxiidae as a new family of thecate hydroids (Cnidaria: Hydrozoa). Zootaxa 5004(3): 401-429. DOI:10.11646/zootaxa.5004.3.1
Résumé [+] [-]Ten species belonging to the genus Gonaxia Vervoort, 1993 occur in recent collections gathered by KANACONO (2016), KANADEEP (2017) and KANADEEP 2 (2019) expeditions of the French Tropical Deep-Sea Benthos Program in deep waters of the New Caledonian region. They were studied using the classical, morphological approach, supplemented by the first genetic characterization of the genus undertaken so far. Two species are previously undescribed, namely G. incisa Galea, sp. nov. and G. solenoscyphoides Galea, sp. nov. Additional notes on the remaining species are provided, notably the discovery of the female gonothecae of G. crassicaulis Vervoort, 1993 and G. perplexa Vervoort, 1993. Lofty colonies, with distinctive cladia-bearing branches spirally-arranged around the stem, assignable to the recently-described G. plumularioides Galea, 2016 actually represent fully-developed colonies of G. errans Vervoort, 1993, as demonstrated using molecular markers, the latter nominal species having priority. Its unusual, club-shaped, longitudinally-ridged gonothecae, fully free from the stem, are described for the first time. Supplementary notes on the hydrotheca of G. crassicaulis Vervoort, 1993 are provided, together with the description of a distinctive gutter of perisarc channeling the coenosarc of the colony along the lumen of both the stem and cladia. A multi-locus phylogenetic hypothesis of the Macrocolonia supports the establishment of the family Gonaxiidae Maggioni, fam. nov., to accommodate the species dealt with herein.

Résumé [+] [-]Two thecate hydroids, Carpocladus fertilis Vervoort & Watson, 2003 (family Aglaopheniidae Marktanner-Turneretscher, 1890) and Gonaxia constricta (Totton, 1930) (family Gonaxiidae Maggioni, in Galea & Maggioni, 2021), are recorded for the first time from off New Caledonia, thus outside their original area of distribution in New Zealand waters. Specimens of both sexes of C. fertilis occur in the present collection, allowing the first description of its so far unknown female gonothecae. The trophosome of G. constricta, the only known to date, is thoroughly redescribed, pending the discovery of its gonothecae.

Gravier-bonnet N. 2007. Hydroids of New Caledonia from literature study, Compendium of marine species from New Caledonia : second edition II7. Compendium of marine species from New Caledonia : second edition:119-125
Résumé [+] [-]From a brief survey of the literature, it appears that until now only two articles were published during the last century by specialists that are dealing with New Caledonian hydroids. The first was by Redier (1966). From samples collected by Yves Plessis, he described 25 species (including 5 varieties), all already known. Most of them were from the littoral zone and were collected at low tide; a few were from deeper waters (to 40 m depth). The second article was published later on by Vervoort (1993) who studied representatives of the family Sertulariidae in several collections of the Natural History Museum of Paris. The specimens mostly originated from the following oceanographic cruises: Biocal (1985), Lagon (1984, 1985 and 1989), Musorstom 4 (1985), Cha1cal 2 (1986), Biogeocal (1988), Smib 2 (1986), 4 and 5 (1989) and 6 (1990), with two additional sites, a station of the "Vauban" (1978) and a dive of H. Zibrowius (1989). Vervoort recorded 57 species of which 39 were new to Science. Most of the biological material from these cruises came from deep water: only 6 stations were from depths between 28 and 57m, and 77 were from a greater depth (125-860m). More recently, Laboute & Richer de Forges (2004) published a book illustrating the high biodiversity of New Caledonia with many in situ photographs of marine plants and animals. This book includes several pages of beautiful photographs of hydroid colonies, exhibiting part of the macroscopic hydroid fauna observable underwater. It presents interesting illustrations of these animals that are usually little known with divers. Besides, pictures of several species of hydrocorals like milleporids and stylasterids, of pelagic hydroid colonies (Velella and Porpita spp) and of a hydromedusa Aequorea) are also found in this book. From these three publications and from an additional provisional list sent by Bertrand Richer de Forges, the aim for the author was to establish a reliable list of species and to comment on it bearing in mind well known data on hydroids. According to the time dedicated to this project it was not possible to study the entire literature to integrate scattered records from New Caledonia or to discuss additional data related to Pacific hydroids. Moreover, the author never personally studied the New Caledonian hydroid fauna or revised specimens in museum collections: she therefore does not feel responsible of misidentifications that could be found in the list.

Résumé [+] [-]Hypertrophied corallites with irregular septal patterns in the Hawaiian deep-water coral Madrepora kauaiensis Vaughan were interpreted 30 yr ago as possible neoplasms, and this idea has persisted in comparative oncological literature. Many colonies of Madrepora oculata L. with similarly modified corallites are recorded herein from 233 to 604 m depth off northwestern Australia and Japan, In the Formosa Strdit, and in the Banda and Araiura Seas, Indonesia. The affected corallites have a hollow space beneath the interrupted columella. Most specimens had been dried and bleached, leaving no tissue but in some alcohol-preserved Indonesian specimens this cavity was occuped by endoparasitic petrarcid ascothoracidan crustaceans. These are described herein as Petrarca madreporae Grygier, new specles, which is characterized by a posterior lobe on each carapace valve, poorly armed mouthparts, and a bifid penis with fixed rami. The validity of the diagnosis of the petrarcid genus Zibrowia Grygier, 1985 is questioned. The abnormal corallites are provisionally reinterpreted as an unusual kind of petrarcid 'internal gall'.

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification. Frontiers in Marine Science 8: 749078. DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

Résumé [+] [-]Classical morphological taxonomy places the approximately 1400 recognized species of Scleractinia (hard corals) into 27 families, but many aspects of coral evolution remain unclear despite the application of molecular phylogenetic methods. In part, this may be a consequence of such studies focusing on the reef-building (shallow water and zooxanthellate) Scleractinia, and largely ignoring the large number of deep-sea species. To better understand broad patterns of coral evolution, we generated molecular data for a broad and representative range of deep sea scleractinians collected off New Caledonia and Australia during the last decade, and conducted the most comprehensive molecular phylogenetic analysis to date of the order Scleractinia. Methodology: Partial (595 bp) sequences of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene were determined for 65 deep-sea (azooxanthellate) scleractinians and 11 shallow-water species. These new data were aligned with 158 published sequences, generating a 234 taxon dataset representing 25 of the 27 currently recognized scleractinian families. Principal Findings/Conclusions: There was a striking discrepancy between the taxonomic validity of coral families consisting predominantly of deep-sea or shallow-water species. Most families composed predominantly of deep-sea azooxanthellate species were monophyletic in both maximum likelihood and Bayesian analyses but, by contrast (and consistent with previous studies), most families composed predominantly of shallow-water zooxanthellate taxa were polyphyletic, although Acroporidae, Poritidae, Pocilloporidae, and Fungiidae were exceptions to this general pattern. One factor contributing to this inconsistency may be the greater environmental stability of deep-sea environments, effectively removing taxonomic "noise'' contributed by phenotypic plasticity. Our phylogenetic analyses imply that the most basal extant scleractinians are azooxanthellate solitary corals from deep-water, their divergence predating that of the robust and complex corals. Deep-sea corals are likely to be critical to understanding anthozoan evolution and the origins of the Scleractinia.

Résumé [+] [-]The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.

Résumé [+] [-]Over the last decade, molecular phylogenetics has called into question some fundamental aspects of coral systematics. Within the Scleractinia, most families composed exclusively by zooxanthellate species are polyphyletic on the basis of molecular data, and the second most speciose coral family, the Caryophylliidae (most members of which are azooxanthellate), is an unnatural grouping. As part of the process of resolving taxonomic affinities of ‘caryophylliids’, here a new ‘Robust’ scleractinian family (Deltocyathiidae fam. N.) is proposed on the basis of combined molecular (CO1 and 28S rDNA) and morphological data, accommodating the early-diverging clade of traditional caryophylliids (represented today by the genus Deltocyathus). Whereas this family captures the full morphological diversity of the genus Deltocyathus, one species, Deltocyathus magnificus, is an outlier in terms of molecular data, and groups with the ‘Complex’’ coral family Turbinoliidae. Ultrastructural data, however, place D. magnificus within Deltocyathiidae fam. nov. Unfortunately, limited ultrastructural data are as yet available for turbinoliids, but D. magnificus may represent the first documented case of morphological convergence at the microstructural level among scleractinian corals.

Lindner A., Cairns S.D. & Cunningham C.W. 2008. From offshore to onshore: multiple origins of shallow-water corals from deep-sea ancestors. PLoS One 3(6): e2429
Résumé [+] [-]Shallow-water tropical reefs and the deep sea represent the two most diverse marine environments. Understanding the origin and diversification of this biodiversity is a major quest in ecology and evolution. The most prominent and wellsupported explanation, articulated since the first explorations of the deep sea, holds that benthic marine fauna originated in shallow, onshore environments, and diversified into deeper waters. In contrast, evidence that groups of marine organisms originated in the deep sea is limited, and the possibility that deep-water taxa have contributed to the formation of shallowwater communities remains untested with phylogenetic methods. Here we show that stylasterid corals (Cnidaria: Hydrozoa: Stylasteridae)—the second most diverse group of hard corals—originated and diversified extensively in the deep sea, and subsequently invaded shallow waters. Our phylogenetic results show that deep-water stylasterid corals have invaded the shallow-water tropics three times, with one additional invasion of the shallow-water temperate zone. Our results also show that anti-predatory innovations arose in the deep sea, but were not involved in the shallow-water invasions.These findings are the first robust evidence that an important group of tropical shallow-water marine animals evolved from deep-water ancestors.

Résumé [+] [-]Leptohelia flexibilis gen. nov. et sp. nov., the first stylasterid with a combined calcified and non-calcified skeleton, is described from seamounts and the slope off the islands of New Caledonia, in the southwestern Pacific. The new species is distinguished from all other species of the family Stylasteridae by having a non-calcified organic axis, internal to the basal portion of the calcified corallum. The internal axis is flexible and enclosed by a series of up to 10 calcified annuli, allowing passive lateral bending of the colony. Molecular phylogenetic analyses confirm that Leptohelia flexibilis is a stylasterid coral and reveal that the species is closely related to Leptohelia microstylus comb. nov., a southwestern Pacific stylasterid that lacks an internal axis.

Résumé [+] [-]The widespread assumption that COI and other mitochondrial genes will be ineffective DNA barcodes for anthozoan cnidarians has not been well tested for most anthozoans other than scleractinian corals. Here we examine the limitations of mitochondrial gene barcoding in the sub-class Octocorallia, a large, diverse, and ecologically important group of anthozoans. Pairwise genetic distance values (uncorrected p) were compared for three candidate barcoding regions: the Folmer region of COI; a fragment of the octocoral-specific mitochondrial protein-coding gene, msh1; and an extended barcode of msh1 plus COI with a short, adjacent intergenic region (igr1). Intraspecific variation was <0.5%, with most species exhibiting no variation in any of the three gene regions. Interspecific divergence was also low: 18.5% of congeneric morphospecies shared identical COI barcodes, and there was no discernible barcoding gap between intra- and interspecific p values. In a case study to assess regional octocoral biodiversity, COI and msh1 barcodes each identified 70% of morphospecies. In a second case study, a nucleotide character-based analysis correctly identified 70% of species in the temperate genus Alcyonium. Although interspecific genetic distances were 2 X greater for msh1 than COI, each marker identified similar numbers of species in the two case studies, and the extended COI + igr1 + msh1 barcode more effectively discriminated sister taxa in Alcyonium. Although far from perfect for species identification, a COI + igr1 + msh1 barcode nonetheless represents a valuable addition to the depauperate set of characters available for octocoral taxonomy.

Résumé [+] [-]Molecular phylogenetic evidence indicates that the octocoral family Alcyoniidae is highly polyphyletic, with genera distributed across Octocorallia in more than 10 separate clades. Most alcyoniid taxa belong to the large and poorly resolved Holaxonia-Alcyoniina clade of octocorals, but members of at least four genera of Alcyoniidae fall outside of that group. As a first step towards revision of the family, we describe a new genus, Parasphaerasclera gen. n., and family, Parasphaerascleridae fam. n., of Alcyonacea to accommodate species of Eleutherobia Putter, 1900 and Alcyonium Linnaeus, 1758 that have digitiform to digitate or lobate growth forms, completely lack sclerites in the polyps, and have radiates or spheroidal sclerites in the colony surface and interior. Parasphaerascleridae fam. n. constitutes a well-supported clade that is phylogenetically distinct from all other octocoral taxa. We also describe a new genus of Alcyoniidae, Sphaerasclera gen. n., for a species of Eleutherobia with a unique capitate growth form. Sphaerasclera gen. n. is a member of the Anthomastus-Corallium clade of octocorals, but is morphologically and genetically distinct from Anthomastus Verrill, 1878 and Paraminabea Williams & Alderslade, 1999, two similar but dimorphic genera of Alcyoniidae that are its sister taxa. In addition, we have re-assigned two species of Eleutherobia that have clavate to capitate growth forms, polyp sclerites arranged to form a collaret and points, and spindles in the colony interior to Alcyonium, a move that is supported by both morphological and molecular phylogenetic evidence.

Molodtsova T. & Budaeva N. 2007. Modifications of corallum morphology in black corals as an effect of associated fauna. Bulletin of Marine Science 81(3): 469–480
Résumé [+] [-]Antipatharians, or black corals, are colonial anthozoans characterized by a chitinous skeletal axis covered to a varying degree with small spines. Important taxonomic features in this group are the size and the structure of polyps, as well as the skeleton morphology, including the mode of branching and/or pinnulation and the spine morphology. Black corals are a characteristic component of seamount suspension-feeding fauna and they often host abundant associated fauna. We examined ~300 antipatharians with symbiotic polychaetes from oceanic rises of the Indo-Pacific region, representing the two families Myriopathidae and Antipathidae. All examined specimens had symbiotic polychaetes of the families Polynoidae [Benhamipolynoe antipathicola (Benham, 1927)] and Eunicidae (Eunice marianae Hartmann-Schröeder, 1998 and Eunice kristiani Hartmann-Schröeder, 1998). It appeared that the morphology of corallum and to some degree the morphology of the skeletal spines was influenced by symbiotic polychaetes. As these features are of a high taxonomic value in antipatharians, they should be used with a caution in black corals with associated polychaete fauna.

Saropathes margaritae n. sp. differs from the closely related S. scoparia (Totton, 1923) in having shorter curved backward primary pinnules, in a lower order (up to three) of subpinnulation, in more (up to eight) secondary pinnules on each primary, as well as in the size and arrangement of spines. The polypar and abpolypar spines in S. margaritae n. sp. differ in form and size, the maximum height of the polypar spines being up to 0.12 mm. The antipatharian fauna reported from seamounts is discussed and a list of species is provided.

Résumé [+] [-]Two new species of the genus Hexapathes Kinoshita, 1910 (Antipatharia, Cladopathidae, Hexapathinae), H. hivaensis n. sp. from Marquesas Islands and H. alis n. sp. from Fiji, are described. Both species were found on the slope at depths of 400-430 m. Hexapathes hivaensis n. sp. diff ers from the closely related H. heterosticha Kinoshita, 1910 by thicker, distinctly curved and denser arranged lateral pinnules and smaller polyps. Hexapathes alis n. sp. diff ers from the related H. australiensis Opresko, 2003 by the form of the colony and relative length of lateral pinnules. A brief review of the genus Hexapathes is given and the possibility of existence of dimorphic polyps in the genus Heliopathes Opresko, 2003 is discussed.

Molodtsova T.N., Opresko D.M. & Wagner D. 2022. Description of a new and widely distributed species of Bathypathes (Cnidaria: Anthozoa: Antipatharia: Schizopathidae) previously misidentified as Bathypathes alternata Brook, 1889. PeerJ 10: e12638. DOI:10.7717/peerj.12638
Résumé [+] [-]For many years an undescribed species of the genus Bathypathes has been misidentified as Bathypathes alternata Brook, 1889 (a species currently re-assigned to the genus Alternatipathes). This new species is rather common at mid- and lower bathyal depths of the Pacific, Atlantic and Indian oceans, often in areas with high concentrations of commercially valuable cobalt-rich ferromanganese crusts, where it was observed in underwater photo and video transects to occur in high densities. Under the name B. alternata this species is recorded in several inventories and databases. There is an urgent need for a formal description of this misidentified and widely distributed species to avoid further confusion. The new species is superficially similar to A. alternata in having a monopodial corallum and simple, bilateral and alternately arranged pinnules. However, it differs from the former in that it has an upright corallum with a straight pinnulated part (vs. a horizontally bent pinnulated part), pinnules of uniform length and density (vs. decreasing regularly distally), and a constant distal angle formed by the pinnules and the stem along different parts of the corallum (vs. a decreasing distal angle near the top). The new species can therefore be easily distinguished from A. alternata in underwater imagery. We formally describe this new species in the genus Bathypathes and assign it the new name B. pseudoalternata. An extensive synonymy list with previous misidentified records is provided. To evaluate the distributional patterns of the new species we review the geographic distribution of antipatharians reported below 800 m. The majority of the hitherto described lower bathyal and abyssal species have been recorded from one biogeographic province; however, 20 species are known from more than two provinces, and only three species are widely distributed (>5 provinces), including the newly described Bathypathes pseudoalternata. Members of the family Schizopathidae, to which the new species belongs, represent the majority of the lower bathyal (50.54%) and abyssal (82.35%) species.

Résumé [+] [-]A new genus and species of deep-sea Chrysogorgiidae Verrill, 1883, Pseudochrysogorgia bellona n. gen. n. sp., is described from colonies collected in the Coral Sea, West of New Caledonia (southwestern Pacific Ocean). These specimens bear resemblance to the genera Chrysogorgia Duchassaing & Michelotti, 1864 (dichotomously-subdivided branches arising from the main stem in a spiraling fashion; polyps characterized by ornamented sclerites) and Metallogorgia Versluys, 1902 (colony monopodial, hexagonal branching pattern). Additional material collected North of New Zealand (Otara Seamount) is used to complete the description of this new genus. Its taxonomic rank is discussed in light of morphology- and DNA-based phylogenetic inference and analysis of genetic distances among deep-sea chrysogorgiid genera.

Résumé [+] [-]The diversity, ubiquity and prevalence in deep waters of the octocoral family Chrysogorgiidae Verrill, 1883 make it noteworthy as a model system to study radiation and diversification in the deep sea. Here we provide the first comprehensive phylogenetic analysis of the Chrysogorgiidae, and compare phylogeny and depth distribution. Phylogenetic relationships among 10 of 14 currently-described Chrysogorgiidae genera were inferred based on mitochondrial (mtMutS, cox1) and nuclear (18S) markers. Bathymetric distribution was estimated from multiple sources, including museum records, a literature review, and our own sampling records (985 stations, 2345 specimens). Genetic analyses suggest that the Chrysogorgiidae as currently described is a polyphyletic family. Shallow-water genera, and two of eight deep-water genera, appear more closely related to other octocoral families than to the remainder of the monophyletic, deep-water chrysogorgiid genera. Monophyletic chrysogorgiids are composed of strictly (Iridogorgia Verrill, 1883, Metallogorgia Versluys, 1902, Radicipes Stearns, 1883, Pseudochrysogorgia Pante & France, 2010) and predominantly (Chrysogorgia Duchassaing & Michelotti, 1864) deep-sea genera that diversified in situ. This group is sister to gold corals (Primnoidae Milne Edwards, 1857) and deep-sea bamboo corals (Keratoisidinae Gray, 1870), whose diversity also peaks in the deep sea. Nine species of Chrysogorgia that were described from depths shallower than 200 m, and mtMutS haplotypes sequenced from specimens sampled as shallow as 101 m, suggest a shallow-water emergence of some Chrysogorgia species.

Résumé [+] [-]The rare octocoral genus Isidoides Nutting, 1910 was originally placed in the Gorgonellidae (now the Ellisellidae), even though it showed a remarkable similarity to the Isidae (now the Isididae). Isidoides was not classified in the Isididae mostly because the type specimen lacked skeletal nodes, a defining characteristic of that family. The genus was later assigned to the Chrysogorgiidae based on sclerite morphology. Specimens were recently collected in the south-western Pacific, providing material for genetic analysis and detailed characterisation of the morphology, and allowing us to consider the systematic placement of this taxon within the suborder Calcaxonia.Apreviously reported phylogeny allowed us to reject monophyly with the Chrysogorgiidae, and infer a close relationship with the Isididae subfamily Keratoisidinae. While scanning for molecular variation across mitochondrial genes, we discovered a novel gene order that is, based on available data, unique among metazoans. Despite these new data, the systematic placement of Isidoides is still unclear, as (1) the phylogenetic relationships among Isididae subfamilies remain poorly resolved, (2) genetic distances between mitochondrial mtMutS sequences from Isidoides and Keratoisidinae are characteristic of intra-familial distances, and (3) mitochondrial gene rearrangements may occur among confamilial genera. For these reasons, and because a revision of the Isididae is beyond the scope of this contribution, we amend the familial placement of Isidoides to incertae sedis.

Résumé [+] [-]The species of Acryptolaria present in collections from several French expeditions in the western Pacific, mostly in the waters around New Caledonia and neighbouring areas, have been studied. The collection proved to be rich in biodiversity, since 29 species were found, of which 19 new to science, doubling the number of known species in this genus. All the species are described, including measurements, and figured. The unknown coppiniae of several previously described species have been found; these are also described and figured. The study confirmed the key role of the cnidome for species identification.

Résumé [+] [-]The type, size, shape and distribution of nematocysts represent important taxonomic characters that help to identify many hydrozoan species. The Stylasteridae is one of the most species-rich hydroid families. Nevertheless, information about the soft tissue and especially data about the nematocysts are still very scant. Scattered data about nematocysts are available in several taxonomic papers, but unfortunately without the type identification or shape description, this information is not very useful. Therefore, several questions still need answers. What types of nematocysts are present in the stylasterid family? Do nematocysts have a particular distribution in the soft tissue? Could they be considered a useful taxonomic character for the family? Is it possible to hypothesize their functions? In order to answer these questions, we analysed 15 stylasterid species belonging to seven genera. Euryteles, desmonemes, isorhizas and probably also mastigophores were identified. All examined species have euryteles and desmonemes, while isorhizas are recorded in two genera and mastigophores in only one genus. Moreover, the shape of the nematocysts in some species is very distinct. The distribution of nematocysts shows that each species contains, in the coenosarc, all nematocysts of its cnidome, while in the polyps there are only euryteles and desmonemes. Our study showed that in integrating the information about nematocyst type, size, shape and distribution, each species investigated herein has a specific cnidome. Therefore, nematocysts have a taxonomic value for stylasterids and, whenever possible, nematocysts should be included in the species descriptions. Moreover, the possible functions of stylasterid nematocysts are given in relation to their type and distribution.

Résumé [+] [-]Coral skeletons are built by Ca-carbonate (calcite or aragonite) crystals that exhibit distinct morphological patterns and specific spatial arrangements that constitute skeletal microstructures. Additionally, the long-standing recognition that distinct coral species growing in similar conditions are able to record environmental changes with species-specific responses provides convincing evidence that, beyond the thermodynamic rules for chemical precipitation, a biological influence is at work during the crystallization process. Through several series of comparative structural and geochemical (elemental and isotopic) data, this paper aims to firmly establish the specific properties of the distinct major taxonomic units that are commonly gathered as deep-water “corals” in current literature. Moreover, taking advantage of recent micrometric and infra-micrometric observations, attention is drawn to the remarkable similarity of the calcareous material observed at the nanoscale. These observations suggest a common biomineralization model in which mineralogical criteria are not the leading factors for the interpretation of the geochemical measurements.

Résumé [+] [-]Bamboo corals are distinguished from most other octocorals by an articulated skeleton. The nodes are proteinaceous and sclerite-free while the internodes are composed of non-scleritic calcium carbonate. This articulation of the skeleton was thought to be unique and a strong synapomorphy for the family Isididae. Our phylogeny, based on the amplification of mtMutS and 18S, shows an articulating skeleton with sclerite-free nodes has arisen independently at least five times during the evolutionary history of Octocorallia rather than being a synapomorphy characteristic of a monophyletic bamboo coral clade. The family Isididae is currently composed of four subfamilies (Circinisidinae, Isidinae, Keratoisidinae, and Mopseinae). Not only is the family polyphyletic, but our genetic analyses suggest also the subfamily Isidinae is polyphyletic based on current taxonomic classifications, and Mopseinae is not monophyletic. The type, Isis, is found outside of the well-supported Calcaxonia – Pennatulacea clade where the other members of Isididae cluster. The current classification of the family Isididae does not reflect the evolutionary history of an articulated skeleton. To better reflect the evolutionary history of these taxa we propose that three of the four the subfamilies, the genus Isidoides, and genera within the subfamily Isidinae, be elevated to family level to produce a classification with five families with a bamboo-like skeleton: Chelidonisididae, Isididae, Isidoidae, Keratoisididae, and Mopseidae.

Résumé [+] [-]The taxonomy of the order Zoantharia ( = Zoanthidea = Zoanthiniaria) is greatly hampered by the paucity of diagnostic morphological features. To facilitate discrimination between similar zoanthids, a combination of morphological and molecular analyses is applied here. The three most abundant zoanthid species in shallow waters of the southern Chilean fjord region are described. Comparison with other zoanthids using molecular markers reveals that two of them are new to science; these are described as Mesozoanthus fossii gen. n., sp. n. and Epizoanthus fiordicus sp. n. Their representatives grow on rocky substratum and do not live in symbiosis with demosponges. In the less abundant M., fossii, animals tire greyish in colour and resemble members of Parazoanthus in growth form. Individual polyps can be tip to 35 mm long. The more abundant E. fordicus are also greyish; the polyps arise froth thin stolons and reach only 12 mm in length. The third species studied is Parazoanthus elongatus McMurrich, 1904. For these three Chilean zoanthid species, in-situ photographs are presented as well as information on distribution, habitat and associated species. Establishment of the Mesozoanthus Pen. n. is of particular importance to taxonomy in the chaotic suborder Macrocnemina. (C) 2008 Gesellschaft fur Biologische Systemalik. Published by Elsevier GmbH.

Résumé [+] [-]Biogeographical classification schemes such as the Marine Ecoregions of the World (MEOW) have been devel oped for continental shelf depths. The lack of faunal data in the deep sea has led to the development of biogeographical units based on oceanographic characteristics. The aim of this study was to propose biogeo graphical schemes for the Upper Bathyal (200–1000 m) across the Pacific Ocean using octocoral distributions. We retrieved over 200 000 octocoral data records from the Deep Sea Coral Data Portal (DSCDP), Ocean Biogeographic Information System (OBIS), Tropical Deep-Sea Benthos program (French National Museum of Natural History), Queensland Museum from the CIDARIS expeditions, and records retrieved from the Siboga expedition reports. We used cluster analysis to examine octocoral distributions against four different biogeo graphical classification schemes. The classification schemes produced mostly concordant patterns with three major faunal distribution barriers: the North Pacific Current isolates the subarctic units by creating a steep temperature gradient; the Subantarctic Front separates the Subantarctic from the rest of the Pacific; and the East Pacific Barrier separates the East Pacific from the Central and West Pacific. Two other smaller but distinct provinces are the Indo-Pacific where Lower Bathyal genera are found in the Upper Bathyal, and Torres Strait/ Coral Sea characterised by mesophotic genera. We propose 12 biogeographic provinces across the Pacific Ocean Upper Bathyal region from 200 to 1000 m depth based on octocoral distributions. The main driver for these units seems to be temperature, a defining feature of water masses. These units could potentially be subdivided into smaller regions based on habitat. Additionally, the clustering of Ecological Marine Units (EMUs) provides evi dence that the Upper Bathyal should in certain regions be divided vertically into two depth zones based on water masses.

Tu T.H., Dai C.F. & Jeng M.S. 2012. Precious corals (Octocorallia: Coralliidae) from the northern West Pacific region with descriptions of two New Species. Zootaxa 3395(1): 1–17
Résumé [+] [-]Members of the family Coralliidae, known as precious corals, are ecologically and economically important deep sea organisms. However, these organisms are currently threatened by commercial harvesting. In order to create and implement effective conservative strategies, taxonomic knowledge of conservative targets is necessary, but unfortunately the taxonomy of precious corals in this family is still ambiguous. This study provides a review of 15 Coralliidae species from the northern West Pacific region and a key to species identification. In addition, descriptions of two new species, Corallium carusrubrum n. sp. and C. taiwanicum n. sp., as well as a redescription of C. sulcatum Kishinouye, 1903 are included. Corallium carusrubrum n. sp. is distributed on seamounts off northeastern Taiwan. The autozooids of C. carusrubrum n. sp. are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is short and cylindrical rather than typically hemispherical; additionally, there are no long spindles in their tentacles. Corallium taiwanicum n. sp. is distributed in an area off southwestern Taiwan. It has special unique 8-radiates with an oval shape and large projections. Corallium sulcatum is distributed from an area off southwestern Taiwan to western Japan. It has been harvested and traded for decades, but there were no illustrations in its original description, hence a redescription of this species is provided.

Résumé [+] [-]This paper presents the first part of a study of large collections of Hydroida (Cnidaria : Hydrozoa) in the Museum national d'Histoire naturelle, Paris, originating from various expeditions in the Philippines, the eastern part of the Malay Archipelago, the Chesterfield Islands, New Caledonia and the Loyalty Islands. In this first part, genera of the family Sertulariidae Lamouroux, 1812, are reviewed, including new species of the genera Abietinaria Kirchenpauer, 1884 (1 new species), Dictyocladium Allman, 1888 (1 new species), Gonaxia nov. Gen. (20 new species and a new variety), SertularellaGray, 1848 (8 new species and a new subspecies), Symplectoscyphus Marktanner-Turneretscher, 1890 (6 new speciesand a new subspecies), and Thyroscyphus Allman, 1877 (1 new species). In addition to other, already known species from those genera, species of Caminothujaria Von Campenhausen, 1896, Cnidoscyphus Splettstosser, 1929, Dynamena Lamouroux, 1812, Geminella Billard, 1925, Hydrallmania Hincks, 1868, and Idiellana Cotton & Godfrey, 1942, are recorded. Many of the records are considerable range extensions or constitute new records for the Chesterfield Islands, New Caledonia and Loyalty Islands regions. Additional species and genera will be treated in a second part. Noteworthy is the occurrence of the curious new genus Gonaxia with many new species from the New Caledonia area, producing its gonothecae in intimate contact with the axis and its secondary tubules. Remarkable also is the occurrence of two northern Atlantic shallow water hydroids, Hydrallmania falcata (Linnaeus, 1758) and Diphasia attenuata (Hincks, 1861), the latter to be fully described in the sequel to this report, from deep water of the New Caledonia region. In zoogeographic context, the present study reveals a considerable degree of endemism in the deeper water hydroid fauna of the seas bordering New Caledonia and the Loyalty Islands, a phenomenon also observed amongst other groups of marine animals. Further zoogeographic comments will be postponed until a larger part of this highly interesting collection has been fully studied.

Résumé [+] [-]The systematics of bamboo corals of the Family Keratoisididae are evaluated using both DNA sequences and morphological data. Sequence data were obtained from 398 specimens, from which 77 unique haplotypes representing the mtMutS and 18S gene regions were identified. These were aligned with sequences downloaded from GenBank from an additional 12 keratoisids and 6 octocoral outgroups. Phylogenetic analyses recovered seven well-supported major clades, the most recently derived of which consists of several subclades. Each clade and subclade can be characterized by a suite of morphological characters that include axis construction, branching pattern, polyp form, and sclerite type and arrangement. This analysis also shows that keratoisid genera described >100 years ago are paraphyletic and need revision and that a large number of new genera will need to be described.

Résumé [+] [-]Members of genus Iridogorgia Verrill, 1883 are the typical deep-sea megabenthos with only seven species reported. Based on an integrated morphological-molecular approach, eight sampled specimens of Iridogorgia from seamounts in the tropical Western Pacific are identified as three new species, and two known species I. magnispiralis Watling, 2007 and I. densispicula Xu, Zhan, Li and Xu, 2020. Iridogorgia flexilis sp. nov. is unique in having a very broad polyp body base with stout and thick scales. Iridogorgia densispiralis sp. nov. can be distinguished by rods present in both polyps and coenenchyme, and I. verrucosa sp. nov. is characterized by having numerous verrucae in coenenchyme and irregular spindles and scales in the polyp body wall. Phylogenetic analysis based on the nuclear 28S rDNA indicated that I. densispiralis sp. nov. showed close relationships with I. splendens Watling, 2007 and I. verrucosa sp. nov., and I. flexilis sp. nov. formed a sister clade with I. magnispiralis. In addition, due to Rhodaniridogorgia fragilis Watling, 2007 nested into the Iridogorgia clade in mtMutS-COI trees and shared highly similar morphology to the latter, we propose to eliminate the genus Rhodaniridogorgia by establishing a new combination Iridogorgia fragilis (Watling, 2007) comb. nov. and resurrecting I. superba Nutting, 1908.

Résumé [+] [-]Species delimitation in poorly known and diverse taxa is usually performed based on monolocus, DNA-barcoding-like approaches, while multilocus data are often used to test alternative species hypotheses in well-studied groups. We combined both approaches to delimit species in the Xenuroturris/Iotyrris complex, a group of venomous marine gastropods from the Indo-P acific. First, COI sequences were analysed using three methods of species delimitation to propose primary species hypotheses. Second, RAD sequencing data were also obtained and a maximum-likelihood phylogenetic tree produced. We tested the impact of the level of missing data on the robustness of the phylogenetic tree obtained with the RAD-seq data. Alternative species partitions revealed with the COI data set were also tested using the RAD-seq data and the Bayes factor species delimitation method. The congruence between the species hypotheses proposed with the mitochondrial nuclear data sets, together with the morphological variability of the shell and the radula and the distribution pattern, was used to turn the primary species hypotheses into secondary species hypotheses. Allopatric primary species hypotheses defined with the COI gene were interpreted to correspond to intraspecific structure. Most of the species are found sympatrically in the Philippines, and only one is confidently identified as a new species and described as Iotyrris conotaxis n. sp. The results obtained demonstrate the efficiency of the combined monolocus/multilocus approach to delimit species.

Exon-Capture-Based Phylogeny and Diversification of the Venomous Gastropods (Neogastropoda, Conoidea), in Vidal N.(Ed.), Molecular Biology and Evolution 35(10): 2355-2374. DOI:10.1093/molbev/msy144
Résumé [+] [-]Transcriptome-based exon capture methods provide an approach to recover several hundred markers from genomic DNA, allowing for robust phylogenetic estimation at deep timescales. We applied this method to a highly diverse group of venomous marine snails, Conoidea, for which published phylogenetic trees remain mostly unresolved for the deeper nodes. We targeted 850 protein coding genes (678,322 bp) in ca. 120 samples, spanning all (except one) known families of Conoidea and a broad selection of non-Conoidea neogastropods. The capture was successful for most samples, although capture efficiency decreased when DNA libraries were of insufficient quality and/or quantity (dried samples or low starting DNA concentration) and when targeting the most divergent lineages. An average of 75.4% of proteins was recovered, and the resulting tree, reconstructed using both supermatrix (IQ-tree) and supertree (Astral-II, combined with the Weighted Statistical Binning method) approaches, are almost fully supported. A reconstructed fossil-calibrated tree dates the origin of Conoidea to the Lower Cretaceous. We provide descriptions for two new families. The phylogeny revealed in this study provides a robust framework to reinterpret changes in Conoidea anatomy through time. Finally, we used the phylogeny to test the impact of the venom gland and radular type on diversification rates. Our analyses revealed that repeated losses of the venom gland had no effect on diversification rates, while families with a breadth of radula types showed increases in diversification rates, thus suggesting that trophic ecology may have an impact on the evolution of Conoidea.

Résumé [+] [-]Although molluscs feature prominently in the semi-popular and academic literature on marine biodiversity, field surveys largely ignore the small and rare species that form the majority of marine molluscan diversity. As a result of a massive effort to sample the benthic molluscs of a complex tropical coastal environment, 23,238 gastropod specimens representing 259 species of Triphoridae-a family with most adult species ranging from 2 to 10 mm-were obtained from a 45,000 hectares study area off the island of Espiritu Santo, Vanuatu. Most species are represented by fewer than 20 specimens and, despite the intensity of the sampling effort, 13% of the species are unique singletons. Spatial heterogeneity was high: out of 416 sampling events, 187 contained triphorids, and 42% of the species occurred at fewer than 5 stations. Most species were small (68% below 5 mm) or very small (22% below 3 mm). A faunal turnover was documented at around 10 m, and another at around 60 m, at the onset of the "twilight zone" that is particularly difficult to sample. On the order of 70% of the species are probably new to science. When dealing with taxonomically difficult groups a morphospecies segregation approach is operationally appropriate to detect patterns of richness, rarity and spatial turn-over. Very few, if any, conservation surveys have the human and funding resources to carry out baseline surveys of the intensity that generated the results presented here. However, as species numbers are often used to promote the conservation interest of a reef, a bay or a stretch of coast, it is essential to know how the numbers were generated: absolute numbers of species are meaningless unless sampling effort and techniques, area surveyed, and size classes targeted are described. This is very rarely the case, even in the academic literature.

Résumé [+] [-]Most species of the genus Bolma Risso, 1826 live in deep water. This may explain why 17 of the 40 species known today were discovered after 1979 when Beu & Ponder published their revision of the genus. Another new species of the genus Bolma from the deep water off New Caledonia is described here. Bolma Boucheti spec. nov. is a small member of the genus, reaching less than 10 mm height. It is compared with Bolma kreipli Alf, Maestrati & Bouchet, 2010, Bolma fuscolineata Alf & Kreipl, 2009, both also from New Caledonia and Bolma microconcha Kosuge, 1985 which is widely spread in the tropical West Pacific.

Résumé [+] [-]A new pleurotomariid species, Bayerotrochus belauensis new species, collected from the Palau Islands, western Pacific, is described and illustrated. This new species is most similar in shell morphology to B. teramachii (Kuroda, 1955), from which it may be distinguished by its thinner, lighter shell with a taller, more stepped spire and lack of pronounced spiral sculpture along the shell base. Molecular data (COI) show B. belauensis new species to be more closely related to B. boucheti from New Caledonia and B. delicatus from Yap, than to B. teramachii. Bayerotrochus boucheti (Anseeuw and Poppe, 2001) differs in having a broader, more conical spire, a more depressed aperture, and a more darkly pigmented shell with spiral sculpture on the shell base. The recently described B. delicatus S.-P. Zhang, S.Q. Zhang, and Wei, 2016 is easily distinguished by its much smaller size and distinctive shell profile.

Résumé [+] [-]Phanerophthalmus is a genus of Indo-West Pacific sea slugs inhabiting seagrass and coral reefs with up to now seven species currently recognised as valid. The goals of this study are to revise the systematics of Phanerophthalmus, infer its phylogeny and patterns of diversity, as well as study its diet. Morphology was combined with molecular phylogenetics based on two mitochondrial (cytochrome c oxidase subunit I, 16S rRNA) and one nuclear (28S rRNA) genes. Molecular species delimitation methods (ABGD, DISSECT) were employed to aid delimiting species. Diet was assessed by gut content analysis. Seventeen species were recognised, 10 of them new to science (P. albotriangulatum, sp. nov., P. anettae, sp. nov., P. batangas, sp. nov., P. boucheti, sp. nov., P. cerverai, sp. nov., P. lentigines, sp. nov., P. paulayi, sp. nov., P. purpura, sp. nov., P. rudmani, sp. nov., P. tibiricae, sp. nov.). Phanerophthalmus has its highest diversity in the Western Pacific where 13 species occur with a peak in the Coral Triangle (11 species; three only known from here). Diversity decreases towards the Central Pacific with five species and Indian Ocean/Red Sea with four species. Only two species are distributed across the Indo-West Pacific. Preliminary gut content analysis suggests these slugs feed on diatoms.

Résumé [+] [-]We investigated the relationships of the muricid subfamilies Haustrinae, Pagodulinae and the genus Poirieria using a molecular phylogenetic approach on a dataset of three mitochondrial genes (12S, 16S and COI). These taxa form a well-supported clade within Muricidae. The phylogenetic analysis suggests that Poirieria is the sister group of Pagodulinae and that Axymene, Comptella, Pagodula, Paratrophon, Trophonella, Trophonopsis, Xymene, Xymenella, Xymenopsis and Zeatrophon are all worthy of genus-level rank within this subfamily. We propose the use of Enixotrophon for a group of species currently classified in Pagodula. The results also support a new taxonomic arrangement in Haustrinae.

Résumé [+] [-]The Coralliophilinae are a subfamily of Muricidae, with about 200-250 species, mostly from temperate and tropical oceans, that are associated with anthozoans on which they feed. We present here a phylogenetic hyothesis for the subfamily, based on DNA sequences (650 aligned positions) of the mitochondrial 12S rDNA from 42 coralliophilines and six other muricids, as well as one fasciolariid, which serves as the outgroup. Relationships among the muricid subfamilies were not resolved unequivocally, but coralliophiline monophyly was strongly supported. Two major clades emerged within the Coralliophilinae, both well supported in a Bayesian analysis. The genera Coralliophila and Babelomurex as commonly understood, are clearly polyphyletic and in need of redefinition. Our results indicate multiple, independent incursions of Coralliophilinae into deep water habitats, several producing subsequent radiations.

Résumé [+] [-]The subgenus Cymatium (Septa) is here restricted to species closely related to C. rubeculum (Linne, 1758). A lectotype is designated for C. rubeculum, neotypes are designated for C. hepaticum (Röding, 1798) and C. flaveolum (Röding, 1798), C. occidentale (Morch, 1877) (= blacketi Iredale, 1936; = beui Garcia-Talavera, 1985) is recorded from the Indo West Pacific, C. (Septa) marerubrum Garcia-Talavera, 1985 is ranked as a geographic subspecies of C. rubeculum, and three new taxa are named: C. (Septa) bibbeyi n. sp., Philippine Islands; C. (Septa) closeli n. sp., Indian Ocean; and C. (Septa) peasei n. sp., western Pacific. In the subgenus Cymatium (Ranularia), neotypes are designated for C. gutturnium (ROding, 1798) and its synonyms, for C. moniliferum (A. Adams & Reeve, 1850), and for C. pyrulum (A. Adams & Reeve, 1850), a lectotype is designated for C. pseudopyrum (Martin, 1899) (a junior synonym of C. pyrulum), other species distinguished are C. encausticum (Reeve, 1844) and C. exile (Reeve, 1844). And new taxa named are C. andamanense n. sp., Andaman Islands, C. springsteeni n. sp., western Pacific and Red Sea, and C. sinense arthuri n. subsp., Red Sea. Other Ranellidae named are Sassia (Sassia) ponderi n. sp., Queensland, and Distorsio (Distorsio) euconstricta n. sp., Indian Ocean and southwest Pacific. A lectotype selected for Murex reticularis Linne, 1758 is a specimen of the species usually known as Distorsio reticulata (Röding, 1798). In Bursa (Bursa), a lectotype is designated for B. grayana Dunker, 1862 (= B. bujoniopsis Maury, 1917; = B. pacamoni Matthews & Coelho, 1971), western Atlantic, and the similar new Oman to Philippines species B. davidboschi is named. Other Bursa taxa named are B. (Colubrellina) quirihorai n. sp., Philippines, and B. (Colubrellina) latitudo fosteri n. subsp., Philippines. In Bufonaria (Bufonaria), a lectotype designated for Murex rana Linne, 1758 confirms that as the name for the most common western Pacific species, a lectotype designated for Ranella crumena Lamarck, 1816 confirms that as the name for the most common Indian Ocean species, B. elegans (Beck in G. B. Sowerby II, 1836) is illustrated, and the new western Pacific species B. perelegans is named; the four similar species B. nobilis (Reeve, 1844), B. margaritula (Deshayes, 1832), B. gnorima (Melville, 1918), and B. thersites (Redfield, 1846) are distinguished, and the new Madagascar to Philippines species B. ignobilis is named.

Résumé [+] [-]The Ranellidae, Bursidae and Personidae from the New Caledonia region (including the Loyalty Islands, the Coral Sea and the New Hebrides Arc) are monographed based on the results of an extensive collecting effort totalling more than 1000 stations. Seventy-three species are recorded, with numerous range extensions. One of the more remarkable aspects of this fauna is the uniquely diverse deep-water tonnoidean assemblage, dominated by species such as Bursa fijiensis, B. latitudo, B. quirihorai, species of Distorsio, Sassia remensa, and less common small personids in the genera Distorsionella and Personopsis. The number of species of New Caledonian Personidae is the highest yet recorded. The Personopsis species are the first modem ones correctly referred to the genus. Revisions are provided of Biplex, Gyrineum, Cyinatium (Gelagna), the Cymatium vespaceum, C. tenuiliratum and Bursa latitudo species groups, of southwest Pacific species of Sassia, and of several Cymatium (Ranularia) and Distorsio species. New genera proposed are Halgyrineum (Ranellidae) and Distorsomina (Personidae). Seven new species are proposed: Biplex bozzettii (from Somalia and southem India), Gyrineum longicaudatum (from the tropical westem Pacific), Cymatium pemiiketi (from Oman), Distorsio parvimpedita, Distorsionella pseudaphera, Personopsis purpurata and P. trigonaperta (all from New Caledonia). The nomenclature of numerous taxa is stabilized by the designation of neotypes and lectotypes for nominal species named by A.

Beu A.G. 2005. Neogene fossil tonnoidean gastropods of Indonesia. Scripta Geologica 130: 1-186
Résumé [+] [-]Tonnoidean gastropods in K. Martin’s and other collections in the Nationaal Natuurhistorisch Museum, Leiden (and a few other minor collections) are reidentified and classified. The resulting fauna of 99 species is very similar to that of the Indo-West Pacific today, 70% of species still inhabiting the Indonesian region. Species endemic to the Miocene and Pliocene rocks of Indonesia are Bursa sangirana sp. Nov., and two new (unnamed) species similar to Bursina ignobilis (Beu); Cassis depressior Martin and C. preangerensis Martin; Cypraecassis denseplicata (Martin) and an unnamed species of Cypraecassis; Sconsia martini van Regteren Altena and S. pulchra Pannekoek; Echinophoria vandervlerki Martin (possibly a synonym of E. wyvillei (Watson)); Phalium menkrawitense Beets and P. rembangense (Martin); Distorsio denseplicata van Regteren Altena and D. djunggranganensis (Martin); Biplex magnifica (Martin), B. pamotanensis (Martin) and B. perliberalis (Beets); Cymatium (Monoplex) gembacanum (Martin) (?=C. exaratum (Reeve)), C. rembangense (Wanner & Hahn), and C. tjaringinense (Martin); Cymatium (Ranularia) pseudopyrum (Martin) and an unnamed species of C. (Ranularia); Cymatium (Septa) dharmai sp. Nov.; Sassia (Cymatiella) fennemai (Martin), S. (C.) menkrawitensis (Beets) and an unnamed species of S. (Cymatiella); Eudolium erbi (Haanstra & Spiker), E. errabundum (Beets) and E. pamotanense (Martin); Malea(?) papuana (Beets); and Sconsodolium (gen. Nov.) rembangense (Pannekoek). These 30 species (30% of the recorded fauna), and the generic groups Sconsia, Sconsodolium and Sassia (Cymatiella), are all “additional” tropical western Pacific taxa that became extinct before the present day (Sconsia and Sassia (Cymatiella) only locally), as a result of Pleistocene climate change. Species previously included in Bufonaria Schumacher prove to belong in two distinct genera; species closely related to “Bursa” nobilis have a subcentral (rather than mid-left edge) opercular nucleus and are reclassified in Bursina Oyama. “Sconsia” rembangensis Pannekoek is an elongate, axially ridged cassid with a coarsely plicate inner lip; the new genus Sconsodolium is proposed for it. Galeodea bituminata (Martin) and G. carolimartini Beets are both earlier names for the western Pacific species (originally described in the Recent fauna) previously known as G. echinophorella Habe. Eudolium javanum (Martin) is an earlier name for the Indo-West Pacific species (originally described in the Recent fauna) previously known as E. pyriforme (G.B. Sowerby 3rd), whereas E. bituminata Martin is a synonym of the near-cosmopolitan species E. bairdii (Verrill & Smith). Ranella spinosa var. granosa Martin is either an earlier name for the western Pacific species (originally described in the Recent fauna) previously known as Bufonaria perelegans Beu, or a closely similar, but distinct, species. Purpura bantamensis Martin, Cassis tegalensis Martin, Dolium losariense Martin, and Tritonium verbeeki Boettger are all synonyms of Cymatium (Linatella) cingulatum (Lamarck).

Mémoires du Muséum national d'Histoire naturelle 196:269-387, ISBN:978-2-85653-614-8
Résumé [+] [-]Shell, radular, opercular and external anatomical characters are surveyed in world Recent deep-water Cassidae, leading to the recognition of three subfamilies: Cassinae, Oocorythinae and Phaliinae. All Recent species are revised of Galeodea Link, 1807 (=Galeoocorys Kuroda & Habe, 1957), Microsconsia n. gen. and Sconsia Gray, 1847, all included in subfamily Cassinae; of Oocorys Fischer, 1883 (= Benthodolium Verrill & Smith, 1884, = Hadroocorys Quinn, 1980), Eucorys n. gen. (including Oocorys bartschi Rehder, 1943 and O. barbouri Clench & Aguayo, 1939) and Dalium Dall, 1889, all included in subfamily Oocorythinae; and of Echinophoria Sacco, 1890, included in subfamily Phaliinae. New species named are Galeodea plauta n. sp. (northwestern New Zealand), Microsconsia limpusi n. sp. (southeastern Queensland, Australia), and Oocorys grandis n. sp. (central Indian Ocean, and southeastern Atlantic, off Namibia). Galeodea bituminata (Martin, 1933) (based on a Pliocene fossil from Buton Island, Indonesia) is an earlier name for G. echinophorella Habe, 1961; G. carolimartini Beets, 1943 is another earlier name for G. echinophorella. The name usually accepted for the type species of Sconsia, S. striata (Lamarck, 1816), is a junior secondary homonym of S. striata (J. Sowerby, 1812) and the valid name for this species is S. grayi (A. Adams, 1855). Echinophoria kurodai Abbott, 1968 was based on small specimens of E. wyvillei (Watson, 1886), and E. oschei Mühlhäusser, 1992 was based on Indian Ocean specimens of E. wyvillei. Echinophoria carnosa Kuroda & Habe, 1961 is limited to southern Japan to the Philippine Islands.

Beu A.G., Bouchet P. & Tröndlé J. 2012. Tonnoidean gastropods of French Polynesia. Molluscan Research 32(2): 61-120
Résumé [+] [-]The tonnoidean gastropod fauna of French Polynesia (54 species) includes 26 species recorded from the Austral Islands (including 10 from Rapa), 33 species from the Marquesas Islands, 39 from the Society Islands, 32 from the Tuamotu Islands, and 3 from the Tarava Seamounts. Most species have planktotrophic larval development and are distributed from East Africa to eastern Polynesia, but many common western Pacific species are not present. With the possible exception of Semicassis salmonea n. sp. (Cassidae), described from the Marquesas, and Gyrineum pusillum (Ranellidae), restricted to the Austral (and Tuamotu?) Islands in southeastern-most Polynesia, no species is endemic to any individual island groups, but several species with broad overall ranges are known from only one archipelago within French Polynesia. Three species (Monoplex intermedius, Septa peasei, Ranellidae; Distorsio graceiellae, Personidae) are much more common in the Marquesas Islands than further westwards. Three species of Bursidae (Bursa lamarckii, Bursina nobilis, Tutufa tenuigranosa) are recorded only from the Marquesas Islands, whereas the only record of Bursina fijiensis is from the Austral Islands. The two very similar species Bursa asperrima and B. cruentata have a complex distribution; only B. cruentata is common west of Hawaii, and only B. asperrima occurs east of Hawaii, but only B. cruentata has been collected at the Marquesas Islands. Ranella venustula is a synonym of Bursa rhodostoma. Neotypes are designated for Buccinum ponderosum Gmelin, 1791, B. nodulosum Gmelin, 1791, Cassis caputequinum Röding, 1798, C. denticulata Röding, 1798, C. glabra Röding, 1798, C. hamata Röding, 1798, Phalium edentulum Link, 1807, P. quadratum Link, 1807, Buccinum biarmatum Dillwyn, 1817, B. pantherina Dillwyn, 1817, Cassis tenuilabris Menke, 1828, and Dolium rufum Blainville, 1829, and lectotypes are designated for Buccinum cornutum Linnaeus, 1758, Murex bufonius Gmelin, 1791 and Cassis torquata Reeve, 1848.

Bieler R. 1993. Architectonicidae of the Indo-Pacific (Mollusca, Gastropoda). Abhandlungen des Naturwissenschaftlichen Vereins in Hamburg (NF) 30, 376 pp. ISBN:3-437-30758-4
Résumé [+] [-]A systematic monograph of the Recent Indo-Pacific species of the marine family Architectonicidae (Gastropoda: Heterostropha) is presented, based on new field studies, a large part (more than 22,000 specimens in over 50 collections) of the world-wide available collection material, as well as all available type material and original publications. A general introduction to the family is given, concentrating on morphology and anatomy, reproductive biology, habitat and diet, phylogeny and fossil record. The group has a world-wide distribution in warm-temperate to tropical waters and is the only gastropod family possessing heterostrophic ("sinistral") protoconchs in combination with broadly conical, umbilicate, dextral teleoconchs. Architectonicids prey on various groups of zoantharian coelenterates. All members for which data are available have long-range planktotrophic veliger larvae enabling dispersal over great distances, and large areas of distribution (often ranging from Africa to the Central Pacific, sometimes even reaching the western coast of America) have been recognized for many species. A discussion of taxonomic characters emphasizes a "finger-print" pattern of recognized homologous teleoconch spiral ribs, and species-typical size range and shape (and occasionally, sculpture) of the protoconch. Over 250 previously introduced architectonicid species-group names are discussed. Of these, 88 are accepted as valid Indo-Pacific architectonicid species-group taxa, and 83 names are placed in their synonymies. Many others are rejected as unjustified emendations, erroneous subsequent spellings, or non-binominal names. Twenty lndo-Pacific species are described as new to science: Architectonica arcana, A. consobrina, A. gualtierii, Granosolarium excavatum, G. gemmi/ernm, Heliacus geminus, H hyperionis, H nereidis, H oceanitis, H proteus, Pseudotorinia armillata, P. sestertius, P. yaroni, Solatisonax kilburni, S.? orba, S. propinqua, S. rehderi, Spiro/axis argonauta, Sp. cornuarietis, and Sp. exornatus. Eight additional "forms" are recognized that demand further study and remain unnamed. Each recognized taxon is redescribed in detail, with special emphasis on homologous features of the teleoconch and protoconch dimensions. The descriptions are illustrated with 470 light and SEM photographs of type and other relevant specimens, and 150 other illustrations such as distribution maps, histograms and line drawings. Available data on anatomy, reproductive biology, larval development, ecology, and geographical distribution are summarized. The Indo-Pacific Architectonicidae are arranged in 11 genera: Architectonica RODING, 1798 (= Solarium LAMARCK, 1799, Verticillus Jousseaume, 1888), with 16 species and 2 "forms"; Adelphotectonica BIELER, 1987, with 3 species; Philippia GRAY, 1847, with 2 species (one of which of doubtful status); Psilaxis Woodring, 1928, with 2 species; Discotectonica MARWICK, 1931 ( = Acutitectonica HABE, 1961, Russetia GARRARD, 1961 ), with 4 species; Granosolarium SAcco, 1892 ( = Solariaxis DALL, 1892, Claraxis IREDALE, 1936), with 5 species; Solatisonax IREDALE, 1931, with 9 species and 1 "form" (two of which tentatively placed or of doubtful locality); Heliacus 0RBJGNY, 1842 ( = Torinia GRAY, 1842), with 28 species, 1 geographic subspecies and several "forms" of undetermined status, arranged in 6 subgenera: Heliacus s.s., Pyrgoheliacus BIELER, 1987, Torinista IREDALE, 1936 ( = Astronacus WoooRING, 1959), Grandeliacus IREDALE, 1957, Teretropoma Rochebrune, 1881, and Gyriscm TIBERI, 1867; Pseudotorinia SAcco, 1892 (= Awarna MESTAYER, 1930, Calodisculus REHDER, 1935), with 12 species and 4 "forms"; Pseudomalaxis F1sCHER, 1885 ( = Discosolis DALL, 1892, Mangonuia Mestayer, 1930), with 2 species; and Spirolaxis MONTEROSATO, 1913 (= Paurodiscm REHDER, 1935, Aguayodiscus Jaume &. Borro, 1946), with 5 species. Lectotypes are selected for Architectonica nobilis RODING, 1798; Architectonica valenciennesii MoRCH, 1859; Solarium admirandum MELVILL &. STANDEN, 1903; Solarium bicanaliculatum VALENCIENNES, 1832; Solarium dilectum DESHAYES, 1863; Solarium dunkeri HANLEY, 1862; Solarium enoshimense MELVILL, 1891; Solarium granulatum LAMARCK, 1816; Solarium japonicum PILSBRY & STEARNS, 1895; Solarium placentale HINDS, 1844; Torinia aequatorialis THIELE, 1925; Torinia costata Schepman, 1909; Torinia densegranosa Pilsbry, 1905; Torinia discoidea PEASE, 1868; and Torinia gemmulata THIELE, 1925.

Résumé [+] [-]Specimens of the genera Mathilda and Tuba from New Caledonia and the Loyalty Islands are studied, and compared with numerous other nominal mathildid species from the Indo-Pacific and Atlantic Oceans. Diversity is high in this region, with several species showing a much wider distribution in the Indo-Pacific than previously ascertained. Mathilda Semper, 1865 is used sensu lato, including Fimbriatella, Granulicharilda, Mathildona and Opimilda. From the study area thirteen species are diagnosed and compared, and several as yet unnamed forms that need further study are also discussed. Four new species are described, and Mathilda fusca (Okutani & Habe, 1981), previously placed in the turritellid genus Orectospira, is recognized as the largest extant member of the family Mathildidae. Tuba Lea, 1833 is also used sensu lato, including Gegania and Tubena, and is represented by two species (one described as new). Twelve Indo-Pacific species previously referred to as Mathildidae are removed from the family: Mathildona cookiana Dell, 1956 (Epitoniidae); Mathilda elegantula Angas, 1871 (Pyramidellidae ?); M. eurytima Melvill & Standen, 1896 (Cerithiidae); M. gracillima Melvill & Standen, 1901 (Capulidae); M. oppia Hedley, 1907 (Rissoidae); M. opulenta Hedley, 1907 (Cerithiidae); M. rosae Hedley, 1901 (Eulimidae); Eucharilda pleurorbis Laseron, 1951, and Opimilda protolineata Laseron, 1951 (Triphoridae); O. porrigata Laseron, 1951 (Cerithiopsidae ?); Dunkeria pulchella A. Adams, 1860, and D. scabra A. Adams, 1860 (Epitoniidae).

Investigating the Bivalve Tree of Life – an exemplar-based approach combining molecular and novel morphological characters. Invertebrate Systematics 28(1): 32. DOI:10.1071/IS13010
Résumé [+] [-]To re-evaluate the relationships of the major bivalve lineages, we amassed detailed morpho-anatomical, ultrastructural and molecular sequence data for a targeted selection of exemplar bivalves spanning the phylogenetic diversity of the class. We included molecular data for 103 bivalve species (up to five markers) and also analysed a subset of taxa with four additional nuclear protein-encoding genes. Novel as well as historically employed morphological characters were explored, and we systematically disassembled widely used descriptors such as gill and stomach ‘types’. Phylogenetic analyses, conducted using parsimony direct optimisation and probabilistic methods on static alignments (maximum likelihood and Bayesian inference) of the molecular data, both alone and in combination with morphological characters, offer a robust test of bivalve relationships. A calibrated phylogeny also provided insights into the tempo of bivalve evolution. Finally, an analysis of the informativeness of morphological characters showed that sperm ultrastructure characters are among the best morphological features to diagnose bivalve clades, followed by characters of the shell, including its microstructure. Our study found support for monophyly of most broadly recognised higher bivalve taxa, although support was not uniform for Protobranchia. However, monophyly of the bivalves with protobranchiate gills was the best-supported hypothesis with incremental morphological and/or molecular sequence data. Autobranchia, Pteriomorphia, Heteroconchia, Palaeoheterodonta, Archiheterodonta, Euheterodonta, Anomalodesmata and Imparidentia new clade ( = Euheterodonta excluding Anomalodesmata) were recovered across analyses, irrespective of data treatment or analytical framework. Another clade supported by our analyses but not formally recognised in the literature includes Palaeoheterodonta and Archiheterodonta, which emerged under multiple analytical conditions. The origin and diversification of each of these major clades is Cambrian or Ordovician, except for Archiheterodonta, which diverged from Palaeoheterodonta during the Cambrian, but diversified during the Mesozoic. Although the radiation of some lineages was shifted towards the Palaeozoic (Pteriomorphia, Anomalodesmata), or presented a gap between origin and diversification (Archiheterodonta, Unionida), Imparidentia showed steady diversification through the Palaeozoic and Mesozoic. Finally, a classification system with six major monophyletic lineages is proposed to comprise modern Bivalvia: Protobranchia, Pteriomorphia, Palaeoheterodonta, Archiheterodonta, Anomalodesmata and Imparidentia.

Bonfitto A. & Morassi M. 2012. A new sinistral turriform gastropod (Conoidea: Mangeliidae) from Taiwan. Zootaxa 3415: 63–68
Résumé [+] [-]The examination of six specimens of a most peculiar sinistral turrid species from Taiwan housed at the Muséum National d’Histoire Naturelle Paris (MNHN) led us to the recognition of a new species. These specimens resemble members of the Oenopotinae Bogdanov, 1987 recently placed in the Mangeliidae P. Fischer, 1883 (Bouchet et al., 2011; Puillandre et al., 2011). The distinct anal sinus and protoconch sculpture suggests it belongs to the genus Curtitoma Bartsch, 1941. Unfortunately, no living specimen of the present species is available for anatomical, molecular, and radular examination. Asami (1993) estimated that 99% of living Gastropod species are dextral. Most sinistral species are land and freshwater pulmonates. The discovery of this sinistral species is of particular interest as it is the first sinistral species reported in the family Mangeliidae.

Résumé [+] [-]The genus Rimosodaphnella Cossmann, 1916 was proposed for Murex textile Brocchi, 1814, a European Miocene– Pliocene species, and is sometimes thought to be represented in the recent fauna by three Atlantic species. Here, we assign only one Atlantic species, Pleurotoma (Drillia) morra Dall, 1881 distributed from North Carolina to Southern Brazil, to the genus and introduce three new species of Rimosodaphnella from the Indo-Pacific region. One, Rimosodaphnella solomonensis, n. sp. from the Solomon Islands, while two others, Rimosodaphnella tenuipurpurata n. sp. and Rimosodaphnella brunneolineata n. sp., from the Philippines Islands; these findings suggest that the genus may be well represented in the Indo-Pacific region.

DOI:10.1016/j.ympev.2021.107312
Résumé [+] [-]Cryptic species are a common phenomenon in cosmopolitan marine species. The use of molecular tools has often uncovered cryptic species occupying a fraction of the geographic range of the original morphospecies. Ship worms (Teredinidae) are marine bivalves, living in drift and fixed wood, many of which have a conserved morphology across cosmopolitan distributions. Herein novel and GenBank mitochondrial (cytochrome c oxidase subunit I) and nuclear (18S rRNA) DNA sequences are employed to produce a phylogeny of the Teredinidae and delimit a cryptic species pair in the Psiloteredo megotara complex. The anatomy, biogeography, and ecology of P. megotara, Psiloteredo sp. and Nototeredo edax are compared based on private and historic museum collections and a thorough literature review. Morphological and anatomical characters of P. megotara from the North Atlantic and Psiloteredo sp. from Japan were morphologically indistinguishable, and differ in pallet architecture and soft tissue anatomy from N. edax. The two Psiloteredo species were then delimited as genetically distinct species using four molecular-based methods. Consequently, the Northwest Pacific species, Psiloteredo pentago nalis, first synonymized with N. edax and then with P. megotara, is resurrected. Nototeredo edax, P. megotara and P. pentagonalis are redescribed based upon morphological and molecular characters. Phylogenetic analysis further revealed cryptic species complexes within the cosmopolitan species Bankia carinata and possibly addi tional cryptic lineages within the cosmopolitan Lyrodus pedicellatus.

Résumé [+] [-]This paper presents the results from examination and determination of tropical species of Buccinidae from deep water, collected by several expeditions, mainly in the Indo-Pacific area. The material comprises 14 genera and the following new taxa are described : Calliloconcha knudseni (Kermadec Trench, 5480 m), Costaha crosnieri ( S W Indian Ocean, 1740 - 3760 m), Eosipho coriolis (Philippines, 880 m), Eosipho engonia ( SW Indian Ocean, 600 - 1 125 m), Eosipho thorybopus (Mozambique Channel, 400 - 500 m), Kapala bathybius (SE Atlantic, 3550 m), Manaria clandestina (SE Asia, 440-1 490 m), Manaria makassarensis ( S E Asia, 490 - 875 m), Manaria formosa (Mozambique Channel, 400 - 500 m). For the preparation of this paper we have examined material and/or types of almost all previously described deep sea species of tropical buccinids and these are figured and commented on. An appendix lists all Neogene and Recent supraspecific names of Buccinidae proposed after the publication of WENZ' " Handbuch der Palaozoologie " ( 1941 - 43 ).

Bouchet P. 1988. A new Cassid (Mollusca: Gastropoda) from the Coral Sea. Venus 47(1): 11-14
Résumé [+] [-]Cassis abbotti n. sp. is characterized by a smooth polished shell, a poorly developed parietal shield, a narrow aperture with denticulated inner and outer lips, and a bulbous, paucispiral protoconch. It is possibly endemic to the Chesterfield Bellona Plateau, where the holotype was taken in 205 m. The family Cassidae has been monographed in part by Abbott (1968) who recognized about 60 Recent species, the majority of which are Indo-Pacific. The higher classification of the Tonnoidea is revised by Beu (1981) and Waren and Bouchet (MS), and Marum has l~ecently been transferred to the neogastropod family Harpidae (Hughes, 1986) . That the alpha-taxonomy of the family has reached a phase of stability is evidenced by the fact that fewer than 5 taxa in the Cassis-Phalium group have been described or changed status in the 20 years since Abbott's revision. The discovery of a very distinct new Cassis from a depth of 205 m in the Coral Sea was therefore unexpected, and raises questions on generic limits within the family.

Résumé [+] [-]Alcithoe aillaudorum n. sp. is the first Alcithoe known outside New Zealand waters; it is however not consider ed a Gondwanian vicariant relict but is probably a recent 'immigrant that dispersed from New Zealand to New Caledonia via the Norfolk ridge. Lyria exorata n . Sp. Is known from Capel and Kelso Banks, two submerged flat plateaus surrounded by abyssal depths in the Coral Sea. L. habei Okutani, 1979 is a new record for New Caledonia. Records of other Lyria are reviewed and summarized. Although the distribution of Lyria in the Western Pacific corresponds rather well with the limits of the Pacific plate, this distribution appears to be a result of constraints in larval biology rather than a reflection of the plate tectonic history of the area.

Ca/liotectum has a fossil record in the Neogene of the Pacifie region (Okinawa, Indonesia, New Zealand and Ecuador), with a total of 5 species. Ali fossi! records are from deep-water facies. Seven Recent species of Callioteetum are recognised, ail from deep water in tropical latitudes. Three species occur in South-East Asia and the Eastern Indian Ocean, at 200-1660 m depth. Of these, C. tibiaeforme is treated as a polytypic species, with C. johnsoni and C. dupreyae considered to be geographical forms. Calliotectum piersonorum sp. nov. and C. egregium sp. nov. are described from the South-West Pacifie at 450-1060 m depth. Single species occur each in the East Pacifie and in the Caribbean.

Bouchet P. & Sysoev A.V. 1997. Revision of the Recent species of Buccinaria (Gastropoda: Conoidea), a genus of deep-water turrids of Tethyan origin. Venus 56(2): 93-119
Résumé [+] [-]The shell of Buccinaria, with its synonyms Dotomella and Pionotoma, is characterized by a wide subsutural ramp forming a broad, concave depression, and a short, broad siphonal canal. The general appearance is strongly convergent with shells of certain buccinid genera such as Eosipho. Radula and protoconch morphology confirm a placement of the genus in the family Conidae, subfamily Raphitominae. Buccinaria is known back to Miocene deposits of Europe, prior to the closure of Tethys, and persists only in the Indo-West Pacific. Recent species live on bathyal soft bottoms, where they appear to favour poorly oxygenated reducing sediments. The six species (two new) recognized live at depths between 200 and 1200 m. Buccinaria loochooensis, originally described from Neogene deposits of the Ryukyus, is recorded for the first time in the Recent fauna . Pionotoma teramachii and P. pyrum, two Recent nominal species from Japan, are synonymized with Buccinaria jonkeri and B. martini, respectively, both described from the Neogene of Indonesia. Cominella koperbergi and C. retifera fall within the range of variation of, and are synonymized with, Buccinaria jonkeri.

Résumé [+] [-]The new genus Fusulculus, conchologically most similar to Benthobia Dall, 1889 and Zemira H. & A. Adams, 1853, is erected for axially sculptured species of Pseudolividae with shouldered whorls and obsolete labral tooth; the columellar and parietal callus is of very limited extent, and a parietal rib at the adapical end of the inner lip is absent. Two new species, Fusulculus crenatus (type of genus) and F albus are described from bathyal (400-800 m) hard bottoms at tropical and subtropical latitudes in the southwest Pacific. No post-Paleocene species of Pseudolividae are known from the tropical IndoPacific; the habitat of Fusulculus is bathymetrically transitional between those of Benthobia, from abyssal depths, and the various genera from subtidal waters in southern Australia, South Africa and Angola.

Résumé [+] [-]Volutomitra glabella n. sp., from off New Caledonia, is the second representative of the genus from the tropical South-West Pacific, where it has been recorded alive on hard bottoms in 258-525 m. Its anatomy is essentially similar to that of other boreal, Antarctic and Australasian species of Volutomitridae. It is sympatric with the V. vaubani species-complex, from which it differs by its larger adult size (17-25 mm), more vividly coloured shell, and larger protoconch (average diameter 1440,um vs average 1030,um in V. vaubani).

Bouchet P. & Kantor Y.I. 2000. The anatomy and systematics of Latiromitra, a genus of tropical deep-water Ptychatractinae (Gastropoda : Turbinellidae). The Veliger 43(1): 1-23
Résumé [+] [-]The anatomy of Latiromitra Locard, 1897, is very similar to that of other representatives of the Ptychatractinae, notably in the short or very short proboscis, the presence of an accessory salivary gland, the ventral odontophoral retractor passing through the nerve ring, and the position of the buccal mass at the proboscis base in contracted position. Latiromitra differs from Ceratoxancus by its fused salivary glands (clearly separate in Ceratoxancus). Based on anatomical and conchological characters, Cyomesus Quinn, 1981, and Okinawavoluta Noda, 1980, are confirmed and/or placed in the synonymy of Latiromitra. The genus currently comprises 10 Recent and Neogene species, three in the Atlantic, and seven in the Indo-West Pacific, all in deep water at low latitudes. Teramachia chaunax Bayer, 1971, is placed in the synonymy of Latiromitra cryptodon (P. Fischer, 1882), and the Recent Benthovoluta sakashitai Habe, 1976, is placed in the synonymy of the Pliocene Latiromitra okinavensis (MacNeil, 1961). Volutomitra? vitilevensis Ladd, 1982 is placed in Latiromitra. Three new species are described: Latiromitra paiciorum sp. nov. (New Caledonia, 960-1100 m), L. cacozeliana sp. nov. (Vanuatu, 536-775 m), and L. crosnieri sp. nov. (Madagascar and NE of Fiji, 600-800 m). In addition, Mitra styliola Dall, 1927, from off Georgia, USA, is tentatively referred to Latiromitra.

Résumé [+] [-]Based on radular and protoconch morphology, the genus Typhlosyrinx Thiele, 1925 has been successively classified in the subfamily Turriculinae of the family Turridae and in the subfamily Clathurellinae of the family Conidae. It is shown that the protoconch had earlier been misinterpreted, and the presence of a diagonally cancellated sculpture indicates a placement in the conid subfamily Raphitominae. Two conchologically similar genera, based on teleoconch sculpture and radular morphology are recognized: Typhlosyrinx, with axial ribbing on teleoconch spire whorls and a radula with long (250 mum) barbed teeth, and Leiosyrinx n. gen., without axial sculpture and a radula with short (< 100 mum) simplified teeth. Five species (two new) of Typhlosyrinx and four species (all new) of Leiosyrinx are recognized, all at bathyal depths between 280 and 1840 m in the tropical Indo-Pacific and Panamic provinces. The two genera are not known earlier than the Pliocene, where they already occurred in deep-water assemblages.

Bouchet P. & Petit R.E. 2002. New species of deep-water Cancellariidae (Gastropoda) from the southwestern Pacific. The Nautilus 116(3): 95-104
Résumé [+] [-]One new genus and nine new species of Cancellariidae are described from New Caledonia from depths between 200 and 600 meters. They are: Africotriton adelphum new species, Mirandaphera new genus, Mirandaphera cayrei new species, Mirandaphera maestratii new species, Merica marisca new species, Sveltia rocroii new species, Sveltia splendidula new species, Nipponaphera pardalis new species, Nipponaphera cyphoma new species, and Nipponaphera goniata new species. Africotriton adelphum new species is the first species in that genus known from outside South Africa and Australia. The new genus Mirandaphera is characterized by its broad, non-umbilicate shell with very large crenulated axial ribs, and axial columella. The genus is composed of the new species described herein, Mirandaphera maestratii new species and M. cayrei new species, and two other species: M. tosaensis (Habe, 1961) new combination and M. arafurensis (Verhecken, 1997) new combination, from deep water off Japan and the Arafura Sea respectively. Trigonaphera teramachii Habe, 1961 and Agatrix. nodosivaricosa Petuch, 1979 are transferred to Nipponaphera. New species of Merica, Sveltia, and Nipponaphera are the deepest dwelling known representatives in their respective genera.

Résumé [+] [-]Morum clatratum n. sp. and Morum roseum n. sp. are described from depths of 100-200 m in the Marquesas Islands. Mode of development inferred from protoconch morphology and comparison with the protoconchs of Harpa with teleplanic larvae suggests that the new species have planktotrophic larval development, and that they are expected to range widely outside the Marquesas. In addition, Morum kurzi, M. macdonaldi, and M. teramachii, with inferred planktotrophic development, and M. watanabei, with inferred non-planktotrophic development, are newly recorded from South Pacific localities. The distribution of individual species of Morum appears to reflect dispersal during the planktonic phase, rather than movement of the lithospheric plates on the geological scale. The Caribbean Morum oniscus and M. lamarckii, respectively with inferred non-planktotrophic and planktotrophic development, are treated as separate valid species.

Résumé [+] [-]Recent deep-sea explorations in the South Pacific have documented around New Caledonia the most diverse fauna of gastropods of the family Volutomitridae anywhere in the world. Fourteen species (nine new, two remaining unnamed) are recorded, all essentially confined to the 250–750 m depth range. The high number of species in the New Caledonia region does not appear to be an effect of sampling intensity, but appears to result from four factors: regional spatial heterogeneity, frequency of hard substrates, syntopy, and a historical heritage shared with Australia and New Zealand, which until now ranked as the major centre of volutomitrid diversity. In the New Caledonia region, volutomitrids show a marked preference for hard bottoms and up to three species may cooccur in the same dredge haul. Many species appear to have extremely narrow geographical distributions within the region (e.g. a single seamount or a single submerged plateau); conversely, Microvoluta joloensis, the only non-endemic volutomitrid present in New Caledonia, ranges from the Mozambique Channel to Tonga.

Résumé [+] [-]Meganodontia acetabulum is described as a new genus and species of the Lucinidae, based on valves trawled at 256 to 472 m depths on the Tashi fishing ground off the northeastern coast of Taiwan. The new genus is close to Anodontia but differs mainly in the small umbones, the perfectly circular outline, the hinge and ligament, and the large muscle impressions. It is the largest known Recent species of Lucinidae. Other species of bivalves, belonging to families symbiotically associated with chemautotrophic bacteria, have been taken at the same or nearby stations, suggesting that the Tashi fishing ground is a site where chemosymblosis plays an important role in biomass production and ecosystem function.

Résumé [+] [-]The Institut de Recherche pour le Développement (IRD, formerly ORSTOM) and Muséum national d’Histoire naturelle (MNHN) launched in the early 1980s a suite of oceanographic expeditions to sample the deep-water benthos of the tropical South and West Pacific, with emphasis on the 100-1,500 m bathymetric zone. This paper reviews the development of this programme to date. It describes the procedures involved in curating the material collected and the involvement of an international network of taxonomic experts to identify, describe and name the molluscan fauna. So far, 1,028 species of molluscs have been recorded from the New Caledonia Exclusive Economic Zone from depths below 100 m, and 601 of these (58.4%) were new species. An additional 142 new species have been described from other South Pacifi c island groups (Solomon Islands, Vanuatu, Fiji, Wallis and Futuna, Tonga, Marquesas Islands and Austral Islands). However, the hyper-diverse families have essentially remained untouched. Regional differences among island groups are high, and New Caledonia, which has been sampled best, shows several discrete areas of micro-endemism. We speculate that the deep-sea mollusc fauna of New Caledonia may amount to 15-20,000 species, and the corresponding number for the whole South Pacifi c may be in the order of 20-30,000 species.

Résumé [+] [-]Fifteen species of Cancellariidae referable to the genera Zeadmete, Admetula, Fusiaphera, Nipponaphera, and Trigonostoma are reported from depths between 200 and 700 m in New Caledonia and other island groups in the southwest Pacific. Twelve are new species: Zeadmete bathyomon new species, Zeadmete physomon new species, Zeadmete bilix new species, Admetula affluens new species, Admetula marshalli new species, Admetula bathynoma new species, Admetula lutea new species, Admetula emarginata new species, Nipponaphera argo new species, Nipponaphera agastor new species, Nipponaphera tuba new species, and Trigonostoma tryblium new species. All the Recent nominal species of Fusiaphera described from localities throughout the Indo-Pacific area Lire considered to be conspecific, the senior name being Fusiaphera macrospira (Adams and Reeve, 1.850), now with ten synonyms. The ranges of Nipponaphera nodosivaricosa (Petuch, 1.979) and Trigonostoma thysthlon Petit and Harasewych, 1987, are extended to the South Pacific.

Résumé [+] [-]Turrids are a group of small predatory gastropods that are highly diversified in shallow as well as deep water. They sing a hymn to specialisation and rarity. A dataset of 34,810 specimens collected through a quarter-century of qualitative exploration off New Caledonia reveals 1409 species of turrids at depths deeper than 100m. Much of this diversity is constituent of the "rare biosphere": as many as 41% are singletons, and 73% of the species are represented by empty shells only. Species numbers vary with depth, reflecting both differences in sampling intensity and in actual species richness. The richest depth interval is 301-600 m, with 831 species, and a moderately good saturation. By contrast, the 601-1000 m interval, with 389 species, is still far from saturated. The overlap in species composition with other South Pacific tropical island groups (Vanuatu, Fiji, Tonga and the Marquesas) is only 17%, but we lack data to back up extrapolations at broader geographical scales (West Pacific, Indo-Pacific, World Ocean). These results champion the slopes of tropical islands, consisting mostly of highly heterogeneous hard bottoms, as a vast reservoir of biodiversity. However, the technological challenges associated with sampling hard bottoms and the geographical remoteness of these target areas combine in making these benthic communities among the least sampled and least studied in the world.

Résumé [+] [-]A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s. (16) and Strictispiridae (2). A diagnosis with description of the shell and radulae is provided for each of these families.

Résumé [+] [-]Seven species of Hydroginella are described as new from bathyal levels off the Fiji Islands. The high diversity presented by Hydroginella in Fiji at bathyal levels is compared with the low diversity presented in the same range by the other Marginellidae genera. This contrasting situation is interpreted as a consequence of a decreasing diversity of most of the Marginellidae genera eastward from New Caledonia, due to their non-planktotrophic development, and of the special dispersive capacity of Hydroginella, attributable to their parasitic behaviour on 'sleeping fishes'.

Résumé [+] [-]Thirty five species attributed to Serrata Jousseaume, 1875 are recognized from the bathyal zone of New Caledonia. Four of these, S. beatrix (Cossignani, 2001), S. tuii (Cossignani, 2001), S. stylaster (Boyer, 2001) and S. boucheti (Boyer, 2001), were previously described in other genera, and 31 other species are here described as new. This series of 35 Serrata species from New Caledonia increases fi ve-fold the Recent specifi c diversity recognized in the genus. The diversity of Serrata species from New Caledonia is inferred to be very partially known, based on the fact that 31% of the identifi ed species are represented in the collections by only one specimen and that 51% were collected at only single stations. The important Serrata fauna documented here has an asymmetrical geographical distribution in New Caledonia, the highest diversity of species being found off far southern New Caledonia and on the northern Norfolk Ridge. The Serrata fauna from New Caledonia, the Loyalty Ridge and the Norfolk Ridge appears to be isolated in the southwest Pacifi c, but it has affi nities with several species occurring in the fossil or Recent fauna of Australia and New Zealand. The fossil distribution of Serrata extends from the Eocene of Alabama to the Pliocene of New Zealand. The distribution of the genus in the Recent seems to be restricted mostly to the southern Indo-Pacifi c latitudes from Cape Agulhas to the Tuamotu Islands, with maximum diversity from the Australian Platform to the Norfolk and New Caledonia Ridges. The fossil genera Euryentome Cossmann, 1899 and Conuginella Laseron, 1957 and the Recent genera Deviginella Laseron, 1957 and Serrataginella Coovert & Coovert, 1995 are proposed as junior synonyms of Serrata. Marginella anatina Lea, 1833 is used instead of Euryentome silabra Palmer, 1937 as the valid name for the type species of the genus Euryentome. The fossil genus Strombiginella Laseron, 1957 is placed in synonymy with the recent genus Hydroginella Laseron, 1957. Serrata and Hydroginella do not seem more closely related to each other than they are to Volvarina-Prunum or to the Austroginella and Dentimargo groups. The “Serrata Group” sensu Coovert & Coovert 1995, composed of Hydroginella, Serrata and 3 synonymous genera, is rejected as being a possibly polyphyletic assemblage. The high disparity in the specifi c shell morphologies of Serrata, the frequent combination of features found as typical in Volvarina and Dentimargo in the Recent, the occurrence of many morphological intergrades between these genera since the Mid-Eocene of the western Tethys sea, and the higher specifi c frequency of the plesiomorphic character of a radula with numerous cusps, together suggest that the genus Serrata may be situated near the base of the common stem from which most of the Recent groups of the Volvarina-Dentimargo complex have differentiated.

Résumé [+] [-]The seamounts chain offers a set of fragmented habitats in which species with poor dispersive ability may undergo divergence in allopatry. Such a scenario may explain the endemism often described on seamounts. In gastropods, it is possible to infer the mode of development of a species from the morphology of its larval shell. Accordingly, we examine the population genetics of several caenogastropods from the Norfolk and Lord Howe seamounts (south-west Pacific) with contrasting modes of larval development. A prerequisite to our study was to clarify the taxonomic framework. The species delimitation was ruled using an integrative approach, based on both morphological and molecular evidence. Molecular data indicate an unexpected taxonomic diversity within the existing species names. Both the clarification of the taxonomic framework and the importance of the sampling effort allow us to confidently detect cryptic diversity and micro-endemism. These results are discussed in relation to the dispersive capacities of the organisms. (C) 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 100, 420-438.

Molluskan species richness and endemism on New Caledonian seamounts: Are they enhanced compared to adjacent slopes?. Deep Sea Research Part I: Oceanographic Research Papers 58(6): 637-646. DOI:10.1016/j.dsr.2011.03.008
Résumé [+] [-]Seamounts were often considered as‘hotspots of diversity’ and ‘centers of endemism’,but recently this opinion has been challenged. After 25 years of exploration and the work of numerous taxonomists, the Norfolk Ridge (Southwest Pacific) is probably one of the best-studied seamount chains worldwide. However,even in this intensively explored area, the richness and the geographic patterns of diversity are still poorly characterized. Among the benthic organisms,the post-mortem remains of mollusks can supplement live records to comprehensively document geographical distrbutions. Moreover, the accretionary growth of mollusk shells informs us about the lifes pan of the pelagic larva.To compare diversity and level of endemism between the Norfolk Ridge seamounts and the continental slopes of New Caledonia we used species occurrence data drawn from (i) the taxonomic literature on mollusks and (ii) a raw dataset of mainly undescribed deep-sea species of the hyperdiverse Turridae. Patterns of endemism and species richness were analyzed through quantitative indices of endemism and species richness estimates or metrics.To date, 403 gastropods and bivalves species have been recorded on the Norfolk Ridge seamounts. Of these, at least 38 species(10%) are potentially endemic to the seamounts and nearly all of 38 species have protoconchs indicating lecithotrophic larval development. Overall, our results suggest that estimates of species richness and endemism ,when sampling effort is taken into account, were not significantly different between slopes and seamounts. By including in our analyses 347 undescribed morphospecies from the Norfolk Ridge, our results also demonstratet he influence of taxonomic bias on our estimates of species richness and endemism.

Résumé [+] [-]The Terebridae are a diverse family of tropical and subtropical marine, gastropods that use a complex and modular venom apparatus to produce toxins that capture polychaete and enteropneust preys. The complexity of the terebrid venom apparatus suggests that venom apparatus development in the Terebridae could be linked to the diversification of the group and can be analyzed within a molecular phylogenetic scaffold to better understand terebrid evolution. Presented here is a molecular phylogeny of 89 terebrid species belonging to 12 of the 15 currently accepted genera, based on Bayesian inference and Maximum Likelihood analyses of amplicons of 3 mitochondrial (COI, 165 and 12S) and one nuclear (28S) genes. The evolution of the anatomy of the terebrid venom apparatus was assessed by mapping traits of six related characters: proboscis, venom gland, odontophore, accessory proboscis structure, radula, and salivary glands. A novel result concerning terebrid phylogeny was the discovery of a previously unrecognized lineage, which includes species of Euterebra and Duplicaria. The non-monophyly of most terebrid genera analyzed indicates that the current genus-level classification of the group is plagued with homoplasy and requires further taxonomic investigations. Foregut anatomy in the family Terebridae reveals an inordinate diversity of features that covers the range of variability within the entire superfamily Conoidea, and that hypodermic radulae have likely evolved independently on at least three occasions. These findings illustrate that terebrid venom apparatus evolution is not perfunctory, and involves independent and numerous changes of central features in the foregut anatomy. The multiple emergence of hypodermic marginal radular teeth in terebrids are presumably associated with variable functionalities, suggesting that terebrids have adapted to dietary changes that may have resulted from predator-prey relationships. The anatomical and phylogenetic results presented serve as a starting point to advance investigations about the role of predator-prey interactions in the diversification of the Terebridae and the impact on their peptide toxins, which are promising bioactive compounds for biomedical research and therapeutic drug development.

Résumé [+] [-]Characterizing speciation processes in the sea remains a highly contentious issue because geographic barriers to gene exchange, which are the initial conditions for the allopatric speciation model, are not obvious. Moreover, many benthic marine organisms have long-lived planktonic larvae that allow them to connect distant patches of habitats. We here analyse the pattern of speciation in the gastropod genus Bursa in which all species have long-lived and planktonic-feeding larvae. We use a large taxonomic and ecologic coverage of Bursidae from the Indo-Pacific. We use an integrative approach to taxonomy to give more support to available taxonomic hypotheses. This analysis revealed cryptic lineages and suggest that a taxonomic revision of the family should be performed. A molecular clock calibrated from the fossil record was used to estimate divergence times. We then focus on the three co-existing species living in the deep waters of New Caledonia. Over the wide sampled area, no genetic structure was detected for the three species. We show that among New Caledonia species, Bursa fijiensis and Bursa quirihorai are reciprocally monophyletic. These two species are the two more closely related species in the inferred phylogeny. The present biogeographic ranges of the two species and the estimated time of divergence make the scenario of geographic isolation followed by secondary contact unlikely.

Résumé [+] [-]In shelled molluscs, assigning valid species names to independent evolutionary lineages can be a difficult task. Most original descriptions are based on empty shells and the high levels of variation in shape, color and pattern in some groups can make the shell a poor proxy for species-level identification. The deep-sea gastropod turbinid genus Bolma is one such example, where species-level identification based on shell characters alone is challenging. Here, we show that in Bolma both traditional and molecular taxonomic treatments are associated with a number of pitfalls that can lead to biased inferences about species diversity. Challenges derive from the few phylogenetically informative characters of shells, insufficient information provided in original descriptions and sampling artefacts, which at the molecular level in spatially fragmented organisms can blur distinctions between genetically divergent populations and separate species. Based on a comprehensive dataset combining molecular, morphological and distributional data, this study identified several cases of shell-morphological plasticity and convergence. Results also suggest that what was thought to be a set of distinct, range-restricted species corresponds instead to a smaller number of more widespread species. Overall, using an appropriate sampling design, including type localities, allowed us to assign available names to evolutionarily significant units.

Résumé [+] [-]Meloscaphander grandis is a little-known species missing from databases and papers on taxonomic revision and phylogenetic analysis of Scaphandridae. This species is redescribed herein, based on the type specimen and specimens from the abyssal plain adjacent to the Kuril-Kamchatka Trench. A phylogenetic analysis of COI, 16S, and 28S markers show M. grandis to nest within the Scaphander clade. Additionally, Scaphander lignarius and S. bathymophilus are suggested to be a complex of cryptic species. Morphological differences between the genera Meloscaphander and Scaphander are of dubious significance and, when coupled with molecular data, give a strong reason for reconsidering Meloscaphander as a junior synonym of Scaphander. Thus, according to an integrative taxonomic analysis, Meloscaphander grandis has been transferred to the genus Scaphander. The diagnosis of the genus Scaphander is expanded. We propose new combinations as follows: Scaphander grandis (Minichev, 1967) comb. n. for Meloscaphander grandis, Scaphander sibogae (Schepman, 1913) comb. n. for Meloscaphander sibogae, and Scaphander imperceptus (Bouchet, 1975) comb. n. for Meloscaphander imperceptus. Due to the homonymy of Scaphander sibogae Schepman, 1913 (with a sunken spire) and Scaphander sibogae (Schepman, 1913) comb. n. (with an elevated spire), the name S. attenuatus Schepman, 1913 becomes valid for the former species (with a sunken spire).

Résumé [+] [-]Abstract Whelks in the sister-genera Enigmaticolus and Thermosipho (Gastropoda: Buccinidae) commonly inhabit deep-water hydrothermal vents and hydrocarbon seeps. Thermosipho desbruyeresi, originally described from the Lau Basin, was thought to occur in vents across the western Pacific, with Eosipho desbruyeresi nipponensis described from the Okinawa Trough treated as its junior synonym. However, new material collected from vents in the Okinawa Trough and seeps in the South China Sea exhibit key characteristics of Enigmaticolus. Re-examination of the types revealed that Eosipho d. nipponensis is actually morphologically distinct from Thermosipho desbruyeresi. A molecular phylogeny reconstructed using the cytochrome c oxidase subunit I (COI) gene confirmed the placement of both taxa in Enigmaticolus and supported their distinctiveness at the species level. We, therefore, rehabilitate E. d. nipponensis as Enigmaticolus nipponensis comb. nov. and transfer T. desbruyeresi to the same genus, as Enigmaticolus desbruyeresi comb. nov. Our results also revealed that Enigmaticolus monnieri described from east Africa and E. inflatus described from the South China Sea are in fact conspecific with E. nipponensis. We discuss the distribution and biogeography, as well as morphological variability, of Enigmaticolus in the light of these new findings. Thermosipho is then left with only its type species, T. auzendei from the East Pacific vents. We have revised the diagnosis for the two genera, as well as the species included in them.

Résumé [+] [-]We test the competing predictions of allopatric speciation and of ecological speciation by dietary specialization in Drupa, an Indo-Pacific genus of carnivorous marine gastropods in the family Muricidae. We use a well-resolved molecular phylogeny (reconstructed from one nuclear and two mitochondrial genes) to show the validity of the traditional species D. elegans, D. rubusidaeus, D. clathrata, D. morum and D. speciosa. ` Drupa ricinus' is shown to consist of three species: D. ricinus s. s., D. albolabris and a new species, possibly endemic to Japan. ` Purpura' aperta is transferred to Drupa. Despite potential widespread dispersal and a high degree of range overlap among sister species, range sizes between sister species are highly asymmetric, suggesting that speciation has been predominately peripatric. The exception is the sister pair D. ricinus s. s. and D. albolabris, which have symmetric range sizes and are sympatric over broad Indo-Pacific ranges. Such symmetry and extensive sympatry are contrary to the predictions of the (peripatric) allopatric model of speciation. Nevertheless, contrary to the predictions of an ecological speciation model based upon dietary specialization, broad dietary range appears to be identical between the species. Small differences in microhabitat preferences (or hypothetical dietary specialization at a fine taxonomic scale) may have been significant in the speciation process or, if initial divergence was allopatric, in permitting subsequent sympatry. Broad dietary shifts appear to have accompanied more ancient divergences within the genus Drupa.

Résumé [+] [-]The validity of the muricid subfamily Ergalataxinae has recently been confirmed with molecular data, but its composition and the relationships among its constituent genera remain unclear. In order to investigate this, we use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I) to construct a Bayesian phylogeny of 52 ergalataxine species in 18 genera, representing c. 40 of the currently accepted species and 86 of the genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. Our results indicate the polyphyly of many traditional genera, including Morula, Pascula and Orania. In order to improve the correspondence between classification and phylogeny, we restrict the definition of Morula, resurrect Tenguella and elevate Oppomorus to full genus, but describe no new genera. Several species in this analysis could not be identified and may be new, but we do not describe them. Further molecular and morphological analyses, in the context of this framework, should help to resolve the remaining ambiguities in the classification of this subfamily. The oldest fossil member of the Ergalataxinae known to us is of Early Oligocene age.

Résumé [+] [-]The monophyly of the muricid subfamily Rapaninae has recently been confirmed with molecular techniques, but its composition and the relationships among its constituent genera remain unclear. We use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I, COI) to construct a Bayesian phylogeny of 80 rapanine species (73% of the approximately 109 currently accepted), representing 27 of the 31 nominal genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. We propose a revised phylogenetic classification of the Rapaninae, assigning the recognized species to 28 genera. Most of the morphologically-defined rapanine genera are considered valid, including Purpura, Drupa, Thais and Nassa, but many of them are here restricted or redefined so that they are monophyletic. In particular the familiar genus Thais is narrowly restricted to a single species. Many groups previously accepted as subgenera, including Mancinella, Vasula, Thalessa and Thaisella, are here accorded full generic rank. We describe one new genus, Indothais. While we do not formally alter species-level taxonomy, we show molecular evidence for two cryptic species and several instances of probable species synonymy. We estimate the age of diversification of the Rapaninae as Late Cretaceous (75.9 Ma) and of many of its genera as Miocene. (C) 2012 Elseviei Inc. All rights reserved.

Mémoires du Muséum national d'Histoire naturelle 196:115-213, ISBN:978-2-85653-614-8
Résumé [+] [-]Species of the bivalve family Lucinidae form a previously unrecognized and signifi cant component of bivalve assemblages at bathyal depths (150-1000 m) in the Indo-West Pacifi c province. Elliptiolucina labeyriei n. gen., n. sp., from 2570 m, is the deepest-occurring lucinid species. South-East Asian seas, from Taiwan to the Arafura Sea, are a hotspot of deep-water lucinid diversity, with 11 species recorded from the Philippines and 14 from Indonesia. Numerous species are in the 20-50 mm range, with several up to 75-80 mm in size, and Meganodontia acetabulum reaches 150 mm. Several species co-occur with representatives of the Vesicomyidae, characteristic of seep and vent communities. It is hypothesized that the lucinid species of this radiation live in discrete pockets of poorly oxygenated sediments enriched in sulfi de by plant debris from nearby land masses and/or diffuse seeping. A parallel is drawn with the “Calcari a Lucina” from the Miocene of Europe. Nine new genera and 32 new species are described.

Résumé [+] [-]The neogastropod family Fasciolariidae Gray, 1853 – tulips, horse-conchs, spindles, etc., comprises important representatives of tropical and subtropical molluscan assemblages, with over 500 species in the subfamilies Fasciolariinae Gray, 1853, Fusininae Wrigley, 1927 and Peristerniinae Tryon, 1880. Fasciolariids have had a rather complicated taxonomical history, with several genus names for a long time used as waste baskets to group many unrelated species; based on shell characters, recent taxonomic revisions have, however, began to set some order in its taxonomy. The present work is the first molecular approach to the phylogeny of Fasciolariidae based on a multigene dataset, which provides support for fasciolariids, an old group with a fossil record dating back to the Cretaceous. Molecular markers used were the mitochondrial genes 16S rRNA and cytochrome c oxidase subunit I, and the nuclear genes 18S rRNA, 28S rRNA and histone H3, sequenced for up to 116 ingroup taxa and 17 outgroups. Phylogenetic analyses revealed monophyly of Dolicholatirus Bellardi, 1884 and Teralatirus Coomans, 1965, however it was not possible to discern if the group is the sister clade to the remaining fasciolariids; the latter, on the other hand, proved monophyletic and contained highly supported groups. A first split grouped fusinines and Pseudolatirus Bellardi, 1884; a second split grouped the peristerniine genera Peristernia Mörch, 1852 and Fusolatirus Kuroda and Habe, 1971, while the last group comprised fasciolariines and the remaining peristerniines. None of these clades correspond to the present-day accepted circumscription of the three recognized subfamilies.

Deep Downunder: Integrative taxonomy of Austrobela , Spergo , Theta and Austrotheta (Gastropoda: Conoidea: Raphitomidae) from the deep sea of Australia. Journal of Zoological Systematics and Evolutionary Research 59(8): 1718-1753. DOI:10.1111/jzs.12512
Résumé [+] [-]Recent sampling efforts in the deep seas of southern and eastern Australia have generated a wealth of DNA-suitable material of neogastropods of the family Raphitomidae. Based on this material, a molecular phylogeny of the family has revealed a considerable amount of genus and species level lineages previously unknown to science. These taxa are now the focus of current integrative taxonomic research. As part of this ongoing investigation, this study focuses on the genera Austrobela, Austrotheta (both Criscione, Hallan, Puillandre & Fedosov, 2020), Spergo Dall, 1895 and Theta Clarke, 1959. We subjected a comprehensive mitochondrial DNA dataset of representative deep-sea raphitomids to Automatic Barcode Gap Discovery, which recognized 24 primary species hypotheses (PSHs). Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges, 18 of these PSHs were converted to secondary species hypotheses (SSHs). Based on the evidence available, the most likely speciation mechanisms involved were evaluated for each pair of sister SSHs, including niche partitioning. Eleven SSHs were recognized as new and their systematic descriptions are provided herein. Of these, four were attributed to Austrobela, one to Austrotheta, four to Spergo and two to Theta. While all new species are endemic to Australian waters, other species studied herein exhibit wide Indo-Pacific distributions, adding to the growing body of evidence suggesting that wide geographic ranges in deep-sea Raphitomidae are more common than previously assumed.

Résumé [+] [-]The deep sea of temperate south-eastern Australia appears to be a ‘hotspot’ for diversity and endemism of conoidean neogastropods of the family Raphitomidae. Following a series of expeditions in the region, a considerable amount of relevant DNA-suitable material has become available. A molecular phylogeny based on this material has facilitated the identification of diagnostic morphological characters, allowing the circumscription of monophyletic genera and the introduction of several new genus-level taxa. Both named and new genera are presently being investigated through integrative taxonomy, with the discovery of a significant number of undescribed species. As part of this ongoing investigation, our study focuses on the genera Famelica Bouchet & Warén, 1980, Glaciotomella Criscione, Hallan, Fedosov & Puillandre, 2020 and Rimosodaphnella Cossmann, 1914. We subjected a comprehensive mitochondrial DNA dataset of representative deep-sea raphitomids to the species delimitation methods ABGD and ASAP that recognised 18 and 15 primary species hypotheses (PSHs) respectively. Following additional evaluation of shell and radular features, and examination of geographic and bathymetric ranges, nine of these PSHs were converted to secondary species hypotheses (SSHs). Four SSHs (two in Famelica and two in Rimosodaphnella) were recognised as new, and formal descriptions are provided herein.

Where the snails have no name: a molecular phylogeny of Raphitomidae (Neogastropoda: Conoidea) uncovers vast unexplored diversity in the deep seas of temperate southern and eastern Australia. Zoological Journal of the Linnean Society 191(4): 961-1000. DOI:10.1093/zoolinnean/zlaa088
Résumé [+] [-]Abstract Although raphitomid snails are a dominant component of gastropod communities in deep seas worldwide, their systematics is still largely tentative. We assembled the most complete sampling of Raphitomidae from south-eastern Australia to date. Based on morphological and molecular data from this material, we produced a robust phylogenetic framework and used it to delimit genera. For the focus area, our results show a large proportion of undescribed species- and genus-level taxa, 11 of which are formally described herein. We demonstrate that the examination of purely morphological characters rarely suffices for the purpose of accurate genus delimitation. As a result, some traditionally highly diverse raphitomid genera (such as Gymnobela) turn out to be artificial assemblages of several unrelated, mostly undescribed, genus-level lineages. Our data suggest that comparable configurations of shell and radular features, observed at the genus level, commonly do not reflect true phylogenetic relationships. However, our results are inconclusive as to whether homoplasy or conservatism are the drivers of this phenomenon. Accommodating for the inevitable sampling biases, south-eastern Australia appears as a possible hotspot for both raphitomid diversity and endemism, when compared with adjacent areas.

Résumé [+] [-]Fissurellidae are marine gastropods with a worldwide distribution and a rich fossil record. We integrate molecular, geographical and fossil data to reconstruct the fissurellid phylogeny, estimate divergence times and investigate historical routes of oceanic dispersal. With five molecular markers for 143 terminals representing 27 genera, we resolve deep nodes and find that many genera (e.g., Emarginula, Diodora, Fissurella) are not monophyletic and need systematic revision. Several genera classified as Emarginulinae are recovered in Zeidorinae. Future work should prioritize emarginuline genera to improve understanding of ancestral traits and the early evolution of fissurellids. Tree calibration with the fossilized birth-death model indicates that crown fissurellids originated around 175 Ma, and generally resulted in younger ages for the earliest nodes than the node dating approach. Model-based biogeographic reconstruction, supported by fossils, infers an Indo-West Pacific origin, with a westward colonization of new oceans via the Tethys Seaway upon the breakup of Pangea. Western Atlantic clades then served as source for dispersal towards other parts of the globe. As the sister group to all other fissurellids, Rimula is ranked in its own subfamily, Rimulinae stat. nov. New synonyms: Hemitominae syn. nov. of Zeidorinae stat. nov.; Cranopsis syn. nov. of Puncturella; Variegemarginula syn. nov. of Montfortula.

Résumé [+] [-]Absence of resolution in phylogenetic trees, or metaphyly, is a common phenomenon. It mainly results from the fact that each data set has its own limit and can hardly be expected to reconstruct alone an entire hierarchy. Because metaphyly helps point out which regions of a tree merit further investigation, one should not avoid metaphyly but rather should try to detect it by addressing carefully node reliability. In this paper we explore the implication of Inetaphyly for species names. We present a phylogenetic analysis of Discodorididae (Mollusca, Gastropoda, Nudibranchia, Doridina), with an emphasis on relationships among species of Discodoris and its traditionally close 'allies' such as Peltodoris and Anisodoris. We demonstrate that some species must be transferred to different discodoridid subclades with which they share synapomorphies, but that many species form a metaphyletic group At the base of Discodorididae, and therefore cannot be placed in any taxon of genus level. We demonstrate that the current International Code of Zoological Nomenclature does not allow taxonomists to handle this situation because it requires selecting a taxon name of genus rank for every species binomial. Then we evaluate the results provided by new forms of species names, both in a rank-based system, such as the current nomenclature, and a rank-free system. All solutions considered would cause radical changes to the 'spirit' of the current ICZN (and, by extension, to the other current codes). In a rank-free system of nomenclature, such as the PhyloCode, the best result is obtained with an epithet-based form that does not mention supra-specific relationships. Under this method, official species names would take the form 'boboliensis Bergh, 1877', although page numbers and letters can be added for uniqueness purposes. Taxonomists would then be free to add supra-specific taxon names in 'common' species names, such as Discodorididae boholiensis Bergh, 1877 or simply Discodorididae boboliensis. Here we wish to stimulate discussion of a problem that we believe merits wide debate: absence of resolution in phylogenetic reconstruction and its impact on species nomenclature.

Résumé [+] [-]Recent morphological and molecular results on phylogeny of euthyneuran gastropods, which include opisthobranchs and pulmonates, have greatly diminished previous supposed resolution of their phylogenetic relationships. In addition to recent morphological results, sequences of the D1 and D2 domains of the 28S rRNA are here analyzed by parsimony for 31 euthyneuran species. The molecular and previous morphological data sets were not congruent according to an ILD test, and morphological and molecular data could not be analyzed simultaneously. Consequently Bremer’s Combinable Component Consensus was used to obtain a new tree, with the following supported molecular results: monophyly of a new clade of opisthobranchs including actively swimming Euthyneura, i.e., pelagic Gymnosomata and Thecosomata plus benthic Anaspidea; first molecular confirmation of monophylies of Hygrophila, including Chilina, Acteonoidea, and Sacoglossa, which include both shellbearing species and slugs; and new confirmation of the monophyly of Stylommatophora. Morphological characters which support the new clades obtained here are discussed.

Dayrat B. 2010. A monographic Revision of Basal Discodorid Sea Slugs (Mollusca: Gastropoda: Nudibranchia: Doridina). Proceedings of the Californian Academy of Sciences 61(suppl. I): 1-403
Résumé [+] [-]Basal discodorids, with an emphasis on Discodoris and Peltodoris, are revised for the first time. Hundreds od specimens were examined, including all type availables. The individuals variation of morphological characters is evaluated and taken into account for species delineation. Discodorids species are rediscribed based on large numbers of individuals: e.g., 98 individuals were dissected for Sebadoris fragilis (Alder and Hancock, 1864). The nomenclature status (valid name, synonym, nomen dubium) of 125 species names is adressed. Prior to the present study, there were 106 valid names, 13 synonyms, two nomina dubia, three permanently invalid names, one nomen nudum; after revision, there are 39 valid names, 12 synonyms (out of the 13 former synonyms), 25 new synonyms, 27 nomina dubia, three permanently invalid names, one nomen nudum, and 18 names that refer to poorly-know species (which could be nomina dubia, synonyms or valid names). Those numbers confirm again the critical need for taxonomic revisions in order to obtain a reliable knowledge on species biodiversity. Also, the high proportion of new synontyms and new nomina dubia is related to the fact that many discodorids were described based on few specimens (of the 81 Discodoris species names, only five were originally created with more than 4 specimens). Another important factor that explains the high proportion of new synonyms and nomina dubia is the large number of incomplete originale descriptions. The supra-specific relationships of all species considered are addressed based on cladistic analysis. Discodoris is a clade including only two of all the former Discodoris species: Discodoris boholiensis Bergh, 1877, the type species of Discodoris under the ICZN, and Discodoris cebuensis Bergh, 1877. Peltodoris is a clade including only three species: Peltodoris atromaculata Bergh, 1880, the type speces of Peltodoris under the ICZN, Peltodoris mullineri Millen and Bertsch, 2000, and Peltodoris murrea (Abraham, 1877). Also, several species are re-allocated to different discodorid clades: e.g., Discodoris fragilis (Alder and Hancock, 1864) transferred to Sebadoris, Doris raripilosa Abraham, 1877 to Asteronotus, and Discodoris crawfordi Burn, 1969 to Rostanga. However, 50 species (including 21 valid species, 17 nomina dubia, and 12 poorly know species) could not be places in any of the discodorid clades (genera), and therefore are part of a metaphyletic group at the base of Discodorididae. There are 50 species names for which we cannot use a generic name as the first part of the Linnaean binomial. This situation is handled in two ways. First, "Montereina", is used as a genus name for all the species that are part of the metaphyletic group at the base of Discodorididae (the quotation marks indicate that this genus name does not refer to a clade), which is compatible with the ICZN but contradicts phylogenetic principles. Second, the clade name Discodorididae is used as a clade address for those species that cannot be placed in a clade of "generic" rank, which is compatible with the International Code of Phylogenetic Nomenclature (ICPN), or PhyloCode. The use of a supra-generic name instead of a generic name in front of a specific name is implemented in a monographic revision for the first time here, and represents a major change in our nomenclature practices. The vast majority of the species regarded as valid here are efficently delineated based on morphological features (mainly the dorsal color, the shape of the radular teeth, and the reproductive system). However, in a few cases, such as in Tayuva, it seems that species cannot be distinguished morphologically. Future possible studies that could help solve those taxonomic issues are discussed. Seven new species are describes. However, those new species are not formally named for a variety of reasons (mainly because not enough information was available). Finally, many new records are provided, especially from the tropical Indo-West Pacific.

Dayrat B., Goulding T.C., Khalil M., Lozouet P. & Tan S.H. 2018. Systematic revision one clade at a time: A new genus of onchidiid slugs from the Indo-West Pacific (Gastropoda: Euthyneura: Pulmonata). RAFFLES BULLETIN OF ZOOLOGY: 24
Résumé [+] [-]In the context of a complete revision of the Onchidiidae, it is shown here that Onchidium vaigiense Quoy & Gaimard, 1825 and Onchidium marmoratum Lesson, 1831 belong to a clade that is separate from all other onchidiid genera and so a new genus is described: Marmaronchis Dayrat & Goulding, new genus. Marmaronchis slugs are characterised by a unique combination of anatomical traits: intestinal loops of type I, rectal gland present, accessory penial gland present. Marmaronchis vaigiensis and M. marmoratus are cryptic externally and internally but are delineated as distinct species with both mitochondrial (COI, 16S, 12S) and nuclear (ITS2, 28S, H3) DNA sequences. Onchidium ambiguum Semper, 1880 and O. steenstrupii Semper, 1882 are proposed as new junior synonyms of M. vaigiensis. Marmaronchis slugs primarily live in the rocky intertidal and, unlike many onchidiids from Southeast Asia, they are not found inside mangroves. Both Marmaronchis species are geographically sympatric and can even be found at the same stations, but Marmaronchis vaigiensis is widely distributed, from the Nicobar Islands (Bay of Bengal) all the way to Vanuatu and the Philippines, while M. marmoratus is only known from New Ireland and Madang (Papua New Guinea). Several new geographical records are provided: Bali and Sulawesi (Indonesia) and Vanuatu for M. vaigiensis; Madang (Papua New Guinea) for M. marmoratus. The diversity of Marmaronchis slugs is compared to other onchidiid genera.

Résumé [+] [-]A new species, Onchidium melakense Dayrat & Goulding, sp. nov., is described, bringing the total to four known species in the genus Onchidium Buchannan, 1800. Onchidium melakense is a rare species with only nine individuals found at three mangrove sites in the Andaman Islands and the Strait of Malacca (western Peninsular Malaysia and eastern Sumatra). The new species is delineated based on mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) DNA sequences as well as comparative anatomy. Each Onchidium species is characterized by a distinct color and can easily be identified in the field, even in the Strait of Malacca where there are three sympatric Onchidium species. An identification key is provided. In addition, Onchidium stuxbergi (Westerlund, 1883) is recorded for the first time from eastern Sumatra, and Onchidium pallidipes Tapparone-Canefri, 1889, of which the type material is described and illustrated here, is regarded as a new junior synonym of O. stuxbergi.

Résumé [+] [-]The genus Peronia Fleming, 1822 includes all the onchidiid slugs with dorsal gills. Its taxonomy is revised for the first time based on a large collection of fresh material from the entire Indo-West Pacific, from South Africa to Hawaii. Nine species are supported by mitochondrial (COI and 16S) and nuclear (ITS2 and 28S) sequences as well as comparative anatomy. All types available were examined and the nomenclatural status of each existing name in the genus is addressed. Of 31 Peronia species-group names available, 27 are regarded as invalid (twenty-one synonyms, sixteen of which are new, five nomina dubia , and one homonym), and four as valid: Peronia peronii (Cuvier, 1804), Peronia verruculata (Cuvier, 1830), Peronia platei (Hoffmann, 1928), and Peronia madagascariensis (Labbé, 1934a). Five new species names are created: P. griffithsi Dayrat & Goulding, sp. nov. , P. okinawensis Dayrat & Goulding, sp. nov. , P. setoensis Dayrat & Goulding, sp. nov. , P. sydneyensis Dayrat & Goulding, sp. nov. , and P. willani Dayrat & Goulding, sp. nov. Peronia species are cryptic externally but can be distinguished using internal characters, with the exception of P. platei and P. setoensis . The anatomy of most species is described in detail here for the first time. All the secondary literature is commented on and historical specimens from museum collections were also examined to better establish species distributions. The genus Peronia includes two species that are widespread across the Indo-West Pacific ( P. verruculata and P. peronii ) as well as endemic species: P. okinawensis and P. setoensis are endemic to Japan, and P. willani is endemic to Northern Territory, Australia. Many new geographical records are provided, as well as a key to the species using morphological traits.

Résumé [+] [-]Based on the specimens collected during three deep-sea cruises, and deposited at the Muséum National d’Histoire Naturelle (MNHN) in Paris, we analysed the diversity of benthic communities within the EEZ of French Polynesia. The literature and the MNHN database allowed us to inventory 471 species of invertebrates, among which 169 were newly described. We mainly found data for Mollusca, Crustacea, Brachiopoda and Crinoidea. We also found samples from other taxa, which still remain unidentified within the collections of the MNHN. Although this inventory is incomplete, we demonstrate that the deep waters of French Polynesia host unique benthic communities and endemic species. Using diversity and multivariate analyses, we show that the deep-sea benthic communities are structured by depth, habitats, geography and also by the presence of polymetallic crust. Furthermore, by focusing on the molluscs of the central area of French Polynesia, we show that the spectrum of shell size differs among deep-sea habitats. Specifically, shells tend to be smaller on encrusted seamounts than on island slopes. Together with the size range of organisms, low abundance, rarity and endemism designate these habitats as sensitive. These results should thus be taken into account in the evaluation of the expected impact of mining activities on biological communities.

Résumé [+] [-]The neogastropod family Columbellidae is a highly successful group of small, primarily epibenthic marine snails distributed worldwide and most abundant in the tropics. The great diversity of the group makes them attractive for studying evolutionary shifts in gastropod anatomy, morphology, ecology and diversity. The existing classification of the family has been based to a large degree on the morphology of the shell and radula. Indeed, membership in the family is traditionally confirmed using the unique morphology of the radula. To reconstruct columbellid phylogeny and assess monophyly of the group, we assembled a multilocus dataset including five mitochondrial and nuclear genes, for 70 species in 31 genera. Phylogenetic analyses using Bayesian inference and maximum likelihood are not well enough resolved to support a subfamilial classification, but do support the monophyly of the family and of several well-defined genera and supra-generic groupings. Two of the most diverse nominal genera, Mitrella and Anachis, are supported as highly polyphyletic. Overall, the resulting topologies indicate that the generic and subfamilial classification is in need of extensive revision but that phylogenomic data are needed to resolve columbellid relationships.

Résumé [+] [-]The biological exploration of deep-sea benthos off New Caledonia during the years 1978-1989 has yielded a rich mollusc fauna, including 30 species of Pectinoidea. The highest diversity, with 14 species, is observed in the 600-800 m depth interval, and only three species have been collected below 1500 m. The fauna belongs to Propeamussiidae (21 species, all taken alive), Entoliidae (1 species, alive), and Pectinidae (8 species, 6 taken alive). Nine species are new to science: Parvamussium multiliratum, P. retiaculum, P. retiolum, P. squalidulum, P. undisonum, P. vesiculatum, Cyclopecten horridus, C. pellucidulus (Propeamussiidae), and Hyalopecten mireilleae (Pectinidae). Most of the other species are new records for the region. Ten lectotypes are designated, one new synonym and one new combination recognized. This pectinoid fauna shows a strong similarity to that of the wider Indo-Pacific, and marginally to that of northern New Zealand and southeastern Australia.

Gloripallium pallium (Linnaeus, 1758) is recorded as living in the area for the first time. Lectotypes are designated for Similipecten eous (Melvill in Melvill & Standen, 1907) Decatopecten flabelloides (Reeve, 1852), Coralichlamys madreporarum (G.B. Sowerby 2nd., 1842) and Semipallium crouchi (Smith, 1892'). Type localities of 20 taxa and the depository of type material for 19 taxa are given. All taxa are figured and extensive synonymy is presented. Intraspecific variation of most taxa is described. The total geographic distribution of each taxon is outlined. The following taxa may be endemic for the Erythrean subprovince: Propeamussiidae: Parvamussium formosum (Melvill in Meivill & Standen, 1907), P siebenrocki (Sturany, 1901), and P thyrideum (Melvill in Melvil1 & Standen, 1907); Pectinidae: Pecten erythraeensis G.B. Sowerby 2nd, 1842, Gloripallium rnaculosum (ForsskCll, 1775), Laevishlamys superficialis (Forsskal 1775). Two taxa: L. superficialis (Forsskal 1775) and Mimachlamys senatoria (Gmelin, 1791) are recorded from the Little Bitter Lake, Suez Canal. None of the taxa dealt with has migrated into the Mediterranean Sea.

Résumé [+] [-]The genus Cypraeopsis was so far known from two species in the Miocene of Europe and South-East Asia. An unnamed species is here recorded from the upper Oligocene of France and C. superstes sp. Nov. Is described from the Recent bathyal fauna of New Caledonia and Reunion. C. superstes differs from the fossil species by the body whorl being spirally sculptured, by the outer lip undulating as in Pedicularia, and by the protruding, uncovered protoconch. A character tentatively interpreted as progenetic. C. superstes thus appears paradoxically as an evolved relict.

Résumé [+] [-]The Indo-Pacific species of Trivia, Dolichupis and Trivellona are revised, based on the most abundant and comprehensive material ever brought together and reveals a previously unsuspected diversity of Triviinae in the upper bathyal zone (200-500 m) of the tropical West Pacific. The description of this fauna gives an opportunity to reevaluate the validity of numerous species- and genus-group taxa recognized earlier, both in the littoral and deep water zones. The present paper deals with Trivia Broderip, 1837, Decoriatrivia Cate, 1979, Dolichupis Iredale, 1930, and Trivellona Iredale, 1931. A forthcoming study will deal with Trivirostra Jousseaume, 1884, Cleotrivia Iredale, 1930, and Semitrivia Cossmann, 1903. By First Reviser action, Ellatrivia Iredale, 1931 is given precedence over Fossatrivia Iredale, 193 I . Decoriatrivia is treated as a subgenus of Trivia; Dolichupis is regarded as generically distinct from Pusula; the nominal genus Pseudotrivia is synonymized with Trivellona. Trivia (T.) cylindrica sp. novo from the Philippines, and Trivia (T.) vitrosphaera sp. nov., from New Caledonia, represent the first records of Trivia (T.) in the Indo-Pacific. Their deep-water occurrence contrasts with that of the six or so species from the littoral of the temperate and tropical eastern Atlantic. Dolichupis malvabasis sp. nov., a deep water species from the Philippines, is closely related to the type species and sole other representative of Dolichupis, D. producta (Gaskoin, 1836). Nine named and six new species are recognized in Trivellona: T. bulla sp. nov., T. conjonctiva sp. nov., T. oligopleura sp. nov., T. syzygia sp. novo and T. galea sp. nov., all from New Caledonia, and T. eglantina sp. novo from the Philippines. Trivia valerieae Hart, 1996 [= Erato tetatua Hart, 1996, syn. Nov.; First Reviser] is treated as a SW Pacific subspecies of T. paucicostata (Schepman, 1909); T. Shimajiriiensis McNeil, 1961, described from the Pliocene of Okinawa, is now recorded in the Recent fauna of the Philippines. Pusula niasensis Wissema, 1948 is a new synonym of Dolichupis producta (Gaskoin, 1836), Pseudotrivia sagamiensis KUI'oda & Habe, 1971 is a new synonym of T. sibogae (Schepman, 1909), and Fossatrivia suduirauti Lorenz, 1996 is a new synonym of T. speciosa (Kuroda & Cate, 1979). Three nominal species described by Cate (1979) supposedly from the Philippines are shown to be wrongly localized and synonyms of Atlantic taxa: Pseudotrivia samarensis is synonymized with Trivia (T.) arctica (Pulteney, 1799) from Europe, and Pseudotrivia dumaliensis and Niveria (Cleotrivia) aquatanica are both synonymized with Niveria (N) nix Schilder, 1922 from the Caribbean. Decoriatrivia halians Cate, 1979 and D. but'ius Cate, 1979 are both synonymized with Trivia (Decoriatrivia) pauci!irata Sowerby, 1870 from the Panamic Province.

Résumé [+] [-]The genus Platydoris Bergh, 1877 is characterized by a at body, wide mantle margin, and elevated branchial and rhinophoral sheaths. Examination of a number of specimens and a review of the literature have shown that there are at least 20 valid species of the genus Platydoris world-wide. Some of them have previously been described by other authors and are redescribed or discussed here: P. argo, P. scabra, P. cruenta, P. angustipes, P. ellioti, P. formosa, P. inframaculata, P. pulchra, P. sanguinea, P. townsendi, P. capricornensis, P. esakii, P. macfarlandi, P. galbanus, P. carolynae. Six new species are described here: P. inornata, P. ocellata, P. annulata, P. sabulosa, P. cinereobranchiata, P. rolani. Platydoris tabulata is a nomen dubium. Species removed from Platydoris include: Doris hepatica, D. murrea, P. variegata, P. punctatella, P. papillata, P. spinulosa, P. carinata, P. immonda, P. spongilla, P. maculata, P. stomascuta. A phylogenetic analysis was conducted, showing the genus to be monophyletic. There was strong support for a clade of all species of Platydoris included in the analysis except for the nodes containing P. annulata and P. macfarlandi, which are found in deeper water than the rest of the genus. This major clade was further divided into a clade of Atlantic and Eastern Pacific species and a clade of IndoPaci c species, showing a strong biogeographical trend. Important characters separating the clades include ventral pigment around the foot, large ventral spots, the presence of vaginal hooks, and whether the accessory gland enters the atrium on the side of the vagina, the side of the deferent duct, or between the two.

Résumé [+] [-]Quelles sont les étapes qui permettent à un coquillage collecté dans les fonds marins du sud de Madagascar de devenir un objet « scientifique » ? Quelles sont les traductions-circulations qui donnent une nouvelle vie à un mollusque dans des collections, à l’autre bout du monde ? Contrairement à l’idée que la science se produit exclusivement en laboratoire et à travers le jeu exclusif des abstractions, l’article décrit les processus de collecte à grande échelle initiés par le Muséum National d’Histoire Naturelle, qui construisent méticuleusement la base taxonomique de la biologie marine, en manipulant d’intenses flux de spécimens matériels. Cinq dimensions de cette circulation sont précisément analysées : circulation géographique entre six localités (du lieu de collecte aux collections) qui dessinent une sorte de laboratoire distribué, série de manipulations par des individus variés et diversement instrumentés, transferts successifs de contenants permettant de confiner-séparer-emboîter, agrégation progressive d’informations accompagnant le spécimen permettant d’établir sa nouvelle carte d’identité, et enfin, multitude d’accidents de parcours possibles qui bouleversent ces trajectoires linéaires. La complexité de cette chaîne sera largement invisible, alors que cette dynamique field to lab dessine une forme importante de scientifisation.

Résumé [+] [-]Six morphotypes of small mussels (Bivalvia: Mytilidae) were found attached to naturally sunken wood collected in the Bohol Sea (Philippines). These specimens are related to the large Bathymodiolus mussels that are found worldwide at cold seeps and hydrothermal vents. In these habitats, the mytilids harbour sulphur- and methane-oxidizing endosymbionts in their gills and depend on the energy and carbon provided by the symbionts. In this study, bacteria associated with the gills of wood-associated mussels are characterized using molecular and microscopic techniques. The existence of bacteria in the lateral zone of gill filaments in all specimens is demonstrated. Comparative analyses of 16S rRNA gene and adenosine 5'-phosphosulphate (APS) reductase gene sequences indicate that the bacteria are closely related to sulphur-oxidizing endosymbionts of Bathymodiolus. FISHs using specific probes confirm that sulphur oxidizers are by far the most abundant, if not the only bacteria present. Electron micrographs displayed mostly extracellular bacteria located between microvilli at the apical surface of host gill epithelial cells all along the lateral zone of each gill filament. In some specimens, occasional occurrence of intracellular bacteria with similar morphology was noted. This study provides the first molecular evidence for the presence of possible thiotrophic symbiosis in sunken wood ecosystems. With their epibiotic bacteria, wood-associated mussels display a less integrated type of interaction than described in their seep, vent and whale fall relatives.

Résumé [+] [-]Mussels of the subfamily Bathymodiolinae thrive around chimneys emitting hot fluids at deep sea hydrothermal vents, as well as at cold seeps and on sunken organic debris (sunken wood, whale falls). Despite the absence of light-driven primary production in these deep-sea ecosystems, mussels succeed reaching high biomasses in these harsh conditions thanks to chemosynthetic, carbon-fixing bacterial symbionts, located in their gill tissue. Since the discovery of mussel symbioses about three decades ago our knowledge has increased, yet new findings are published regularly regarding their diversity, role and evolution. This article attempts to summarize current knowledge about symbiosis in Bathymodiolinae, focusing on mussel species for which information is available regarding both hosts and symbionts. Moreover, new data obtained from small mussels inhabiting sunken woods around the Philippines are provided. Indeed, mussel species from organic falls remain poorly studied compared to their vent and seep relatives despite their importance for the understanding of the evolution of symbiosis in the subfamily Bathymodiolinae.

Résumé [+] [-]Although most chitons (Mollusca: Polyplacophora) are shallow-water molluscs, diverse species also occur in deep-sea habitats. We investigated the feeding strategies of two species, Leptochiton boucheti and Nierstraszella lineata, recovered on sunken wood sampled in the western Pacific, close to the Vanuatu Islands. The two species display distinctly different associations with bacterial partners. Leptochiton boucheti harbours Mollicutes in regions of its gut epithelium and has no abundant bacterium associated with its gill. Nierstraszella lineata displays no dense gut-associated bacteria, but harbours bacterial filaments attached to its gill epithelium, related to the Deltaproteobacteria symbionts found in gills of the wood-eating limpet Pectinodonta sp. Stable carbon and nitrogen isotope signatures and an absence of cellulolytic activity give evidence against a direct wood-feeding diet; both species are secondary consumers within the wood food web. We suggest that the distinct associations with bacterial partners are linked to niche specialisations of the two species. Nierstraszella lineata is in a taxonomic family restricted to sunken wood and is possibly adapted to more anoxic conditions thanks to its gill-associated bacteria. Leptochiton boucheti is phylogenetically more proximate to an ancestral form not specialised on wood and may itself be more of a generalist; this observation is congruent with its association with Mollicutes, a bacterial clade comprising gutassociated bacteria occurring in several metazoan phyla

Emerson W.K. 1990. New records for Western Pacific Morum (Gastropoda: Harpidae) with biogeographic implications. The Veliger 33(2): 145-154
Résumé [+] [-]Major extensions of tlie known range are reported for six species of the prosobranch genusMorum, namely: M. teramachu, M. uchiyamai and M. joelgreenei in the Mariana Islands, M. uchiyamai and M. bruuni in the region of New Caledonia, M. cancellatum in the Fiji Islands, and M. kurzi in the Solomon Islands. The distributional patterns of the 15 recognized species of Morum living in the Indo- West Pacific biogeographic region are evaluated in terms of the occurrences of these taxa on the regional lithospheric plates. The fossil and modern distributional patterns of Morum (sensu lato) suggest that these gastropods are remnants of a Tethyan faunal element which is limited in distribution owing largely to the apparent lack of teleplanic larvae.

Résumé [+] [-]Four new species of Halgerda from the deep western Pacific Ocean are described. Halgerda fibra n. sp. was found in the Philippines at depths near 90 m and is also recorded from the New Caledonia region in 90-400 m. The new species differs from other Halgerda in its reproductive morphology. The ampulla is larger and more coiled than other Halgerda and the vagina is also much larger and more bulbous than other members of the genus. Halgerda abyssicola n. sp. was found near Vanuatu at depths of 207-280 m and from the Coral Sea in 385-420 m. Its reproductive morphology is unusual for a species of Halgerda in that the penis and vagina are both extremely large and bulbous. Halgerda azteca n. sp. was found near Norfolk Ridge, south of New Caledonia at depths from 230-367 m. Its reproductive morphology differs from other Halgerda species primarily due to its long, coiled ejaculatory duct and prominent vaginal sphincter. Halgerda orstomi n. sp. was found near Vanuatu at depths between 160-251 m; from the Philippines at 92-95 m and from New Caledonia at 120 m. Halgerda orstomi has an unusual vaginal sphincter and bulbous vagina which distinguishes it from other Halgerda species. The ranges and depths of three additional, previously described Halgerda species: H. brunneomaculata Carlson & Hoff, 1993, H. carlsoni Rudman, 1978 and H. dalanghita Fahey & Gosliner, 1999 are also extended.

In addition, characteristics that distinguish each genus currently in use for TWA shallow water species have indicated the need for reassignment (new combinations within Drilliidae) of 15 species. Some nomenclatural actions have come about from the literature review and include one taxon placed in junior synonymy (under an older name recently re-discovered) and one new name for a junior homonym. Two neotypes, five lectotype designations, and one new name are also proposed. Altogether, nomenclatural actions on 17% of valid previously described taxa are proposed. The 100 proposed names are placed in 12 available and one new genus: Agladrillia Woodring, 1928 (2), Bellaspira Conrad, 1868 (7), Calliclava McLean, 1971 (3), Cerodrillia Bartsch & Rehder, 1939 (11), Clathrodrillia Dall, 1918 (6), Decoradrillia, new genus (4), Douglassia Bartsch, 1934 (4), Fenimorea Bartsch, 1934 (15), Leptadrillia Woodring, 1928 (12), Lissodrillia Bartsch & Rehder, 1939 (8), Neodrillia Bartsch, 1943 (2), Splendrillia Hedley, 1922 (13), and Syntomodrillia Woodring, 1928 (13). These are the first reports of Calliclava in the western Atlantic, previously known only from the eastern Pacific. The new genus, Decoradrillia, is proposed to hold four new species and one existing that share a unique shell microsculpture and other morphological traits. One genus, Drillia Gray, 1838, is not currently believed to have TWA representatives. Three genera comprised exclusively of bathyal species are not treated in this work: Clavus Monfort, 1810 (=Eldridgea Bartsch, 1934), Globidrillia Woodring, 1928, and SpirotropisSars, 1878. The significant increase in species within all of the genera has the effect of strengthening the groups’ diagnostic characters by their presence across a greater number of species. Each of the 148 valid species treated herein are described (or redescribed) and photographs of types presented, as are photographs of morphological variants and representatives from separate geographic areas, if available, to illustrate species’ variability.

Résumé [+] [-]In most marine gastropods, the duration of the larval phase is a key feature, strongly influencing species distribution and persistence. Antarctic lineages, in agreement with Thorson's rule, generally show a short pelagic developmental phase (or lack it completely), with very few exceptions. Among them is the ascidian-feeding gastropod family Velutinidae, a quite understudied group. Based on a multilocus (COI, 16S, 28S and ITS2) dataset for 182 specimens collected in Antarctica and other regions worldwide, we investigated the actual Antarctic velutinid diversity, inferred their larval development, tested species genetic connectivity and produced a first phylogenetic framework of the family. We identified 15 Antarctic Molecular Operational Taxonomic Units (MOTUs), some of which represented undescribed species, which show two different types of larval shell, indicating different duration of the Pelagic Larval Phase (PLD). Antarctic velutinids stand as an independent lineage, sister to the rest of the family, with extensive hidden diversity likely produced by rapid radiation. Our phylogenetic framework indicates that this Antarctic flock underwent repeated events of pelagic phase shortening, in agreement with Thorson's rule, yielding species with restricted geographic ranges.

Résumé [+] [-]The systematics of several Eastern Atlantic conoidean species, traditionally ascribed to the genus Raphitoma Bellardi, 1847, are revised on the basis of DNA sequence data from three gene regions (cytochrome c oxidase subunit I, 16S rRNA and 12S rRNA). We assign genus ranking to three major lineages (Raphitoma, Cyrillia Kobelt, 1905 and Leufroyia Monterosato, 1884) and suggest that two West African species belong in the subgenus Daphnella (Paradaphne) Laseron, 1954. A new classification, based on molecular systematics and critical study of morphology, is provided for all Eastern Atlantic and Mediterranean species that are currently ascribed to Raphitoma s.l. The genus Clathromangelia Monterosato, 1884 is confirmed as belonging to Raphitomidae. Phylogenetic relationships and genetic distances suggest that Raphitoma maculosa Høisæter, 2016 and R. obesa Høisæter, 2016 may be divergent morphotypes of R. bicolor (Risso, 1826) and Cyrillia aequalis (Jeffreys, 1867), respectively.

Résumé [+] [-]Profundiconus is the most divergent cone snail genus and its unique phylogenetic position, sister to the rest of the family Conidae, makes it a key taxon for examining venom evolution and diversity. Venom gland and foot transcriptomes of Profundiconus cf. vaubani and Profundiconus neocaledonicus were de novo assembled, annotated, and analyzed for differential expression. One hundred and thirty-seven venom components were identified from P. cf. vaubani and 82 from P. neocaledonicus, with only four shared by both species. The majority of the transcript diversity was composed of putative peptides, including conotoxins, profunditoxins, turripeptides, insulin, and prohormone-4. However, there were also a significant percentage of other putative venom components such as chymotrypsin and L-rhamnose-binding lectin. The large majority of conotoxins appeared to be from new gene superfamilies, three of which are highly different from previously reported venom peptide toxins. Their low conotoxin diversity and the type of insulin found suggested that these species, for which no ecological information are available, have a worm or molluscan diet associated with a narrow dietary breadth. Our results indicate that Profundiconus venom is highly distinct from that of other cone snails, and therefore important for examining venom evolution in the Conidae family.

High cryptic diversity in the kleptoparasitic genus Hyalorisia Dall, 1889 (Littorinimorpha: Capulidae) with the description of nine new species from the Indo-West Pacific. Journal of Molluscan Studies 86(4): 401-421. DOI:10.1093/mollus/eyaa028
Résumé [+] [-]Species in the family Capulidae (Littorinimorpha: Capuloidea) display a wide range of shell morphologies. Several species are known to live in association with other benthic invertebrates—mostly bivalves and sabellid worms, but also other gastropods—and are believed to be kleptoparasitic filter feeders that take advantage of the water current produced by the host. This peculiar trophic ecology, implying a sedentary lifestyle, has resulted in highly convergent shell forms. This is particularly true for the genus Hyalorisia Dall, 1889, which occurs in deep water in the Caribbean and Indo-West Pacific provinces, with two nominal species recognized so far. Combining morphological, ecological and molecular data, we assessed the diversity of the genus, its phylogenetic position inside the family and its association with its bivalve host, the genus Propeamussium de Gregorio, 1884 (Pectinoidea), resulting in the description of nine new cryptic species. When sympatric, species of Hyalorisia are associated with different host species, but the same species of Propeamussium may be the host of several allopatric species of Hyalorisia.

Résumé [+] [-]A remarkably high diversity of native small spindle-shells (Gastropoda, Fasciolariidae, Fusininae) has been recently inventoried in the Mediterranean Sea, with 23 species identified based on shell morphology. They have almost invariably been classified in the genus Fusinus, and a few of them recently moved to other genera (Aptyxis Troschel 1868, Aegeofusinus Russo, 2017 and Gracilipurpura Jousseaume, 1880), mostly based on the sole shell features. We have reconstructed a molecular phylogenetic framework for the Mediterranean Fusininae, focusing on native species representative of the genus-level taxa. Our results confirmed that Fusinus s.s. (type species Murex colus Linnaeus, 1758) should be restricted to a group of large-shelled species from the Indo-West Pacific and does not fit any of the small-shelled Mediterranean fusinines. We confirm that Murex syracusanus Linnaeus, 1758 represents a distinct lineage, and show that for all the remaining species the pattern is suggestive of a single monophyletic radiation of small Mediterranean fusinines, for which the name Pseudofusus Monterosato, 1884 must be used

Neither slugs nor snails: a molecular reappraisal of the gastropod family Velutinidae. Zoological Journal of the Linnean Society: 1-41. DOI:10.1093/zoolinnean/zlac091
Résumé [+] [-]Abstract The systematics of the marine mollusc family Velutinidae has long been neglected by taxonomists, mainly because their often internal and fragile shells offer no morphological characters. Velutinids are usually undersampled owing to their cryptic mantle coloration on the solitary, social or colonial ascidians on which they feed and lay eggs. In this study, we address the worldwide diversity and phylogeny of Velutinidae based on the largest molecular dataset (313 specimens) to date, accounting for > 50% of the currently accepted genera, coupled with morphological and ecological data. Velutinids emerge as a diverse group, encompassing four independent subfamily-level lineages, two of which are newly described herein: Marseniopsinae subfam. nov. and Hainotinae subfam. nov. High diversity was found at genus and species levels, with two newly described genera (Variolipallium gen. nov. and Pacifica gen. nov.) and ≥ 86 species in the assayed dataset, 58 of which are new to science (67%). Velutinidae show a remarkable morphological plasticity in shell morphology, mantle extension and chromatic patterns. This variability is likely to be the result of different selective forces, including habitat, depth and trophic interactions.

Résumé [+] [-]Background: Planaxis sulcatus has been touted as a textbook example of poecilogony, with members of this wideranging Indo-Pacific marine gastropod said to produce free-swimming veligers as well as brooded juveniles. A recent paper by Wiggering et al. (BMC Evol Biol 20:76, 2020) assessed a mitochondrial gene phylogeny based on partial COI and 16S rRNA sequences for 31 individuals supplemented by observations from the brood pouch of 64 mostly unsequenced individuals. ABGD and bGYMC supported three reciprocally monophyletic clades, with two distributed in the Indo-Pacific, and one restricted to the northern Indian Ocean and Red Sea. Given an apparent lack of correlation between clade membership and morphological differentiation or mode of development, the reported 3.08% maximum K2P model-corrected genetic divergence in COI among all specimens was concluded to represent population structuring. Hence, the hypothesis that phylogenetic structure is evidence of cryptic species was rejected and P. sulcatus was concluded to represent a case of geographic poecilogony. Results: Our goal was to reassess the case for poecilogony in Planaxis sulcatus with a larger molecular dataset and expanded geographic coverage. We sequenced an additional 55 individuals and included published and unpublished sequence data from other sources, including from Wiggering et al. Our dataset comprised 108 individuals (88 COI, 81 16S rRNA) and included nine countries unrepresented in the previous study. The expanded molecular dataset yielded a maximum K2P model-corrected genetic divergence among all sequenced specimens of 12.09%. The value of 3.08% erroneously reported by Wiggering et al. is the prior maximal distance value that yields a single-species partition in ABGD, and not the maximum K2P intraspecific divergence that can be calculated for the dataset. The bGMYC analysis recognized between two and six subdivisions, while the best-scoring ASAP partitions recognized two, four, or five subdivisions, not all of which were robustly supported in Bayesian and maximum likelihood phylogenetic analyses of the concatenated and single gene datasets. These hypotheses yielded maximum intra-clade genetic distances in COI of 2.56–6.19%, which are more consistent with hypothesized species-level thresholds for marine caenogastropods. Conclusions: Based on our analyses of a more comprehensive dataset, we conclude that the evidence marshalled by Wiggering et al. in support of Planaxis sulcatus comprising a single widespread, highly variable species with geographic poecilogony is unconvincing and requires further investigation in an integrative taxonomic framework.

Résumé [+] [-]Two new species of Horaiclavus, lacking radula, venom gland and proboscis, are described. The genus is placed in the subfamily Crassispirinae (Turridae). Both species possess a peculiar foregut structure, the muscular rhynchodaeal outgrowth situated in the rhynchocoel. The possible function of the rhynchodaeal outgrowth is discussed. Other studied species of Horaiclavus possess a radula of a typical ‘crassispirine’ type but lack the outgrowth. The anatomy of the foregut of the new species is superficially similar to that of Zemacies excelsa (Turridae: Zemaciinae), which also possesses an additional structure of the rhynchocoel, namely the ‘pyriform gland’. Conchologically, there is no resemblance between Zemacies and Horaiclavus and it is concluded that similar foregut arrangement appeared independently in both lineages. A new monotypic subfamily Zemaciinae was erected mostly on the basis of the unique foregut arrangement of Zemacies excelsa. We express doubts concerning the importance of these characters in establishing a new taxon of subfamilial rank and therefore the validity of the subfamily Zemaciinae.

Résumé [+] [-]The neogastropod family Costellariidae is a large and successful group of carnivorous marine mollusks that encompasses about 475 living species. Costellariids are most diverse in the tropical Indo-Pacific at a depth interval of 0–200 m, where they are largely represented by numerous species commonly assigned to the genus Vexillum. The present work expands the taxon sampling of a previous phylogeny of the mitriform gastropods to resolve earlier problematic relationships, and thus establish a robust framework of the family, revise its taxonomy, and uncover major trends in the evolution of costellariid morphology. A multicuspidate rachidian is shown to have appeared at least twice in the evolutionary history of the family: it is regarded as an apomorphy of the primarily Indo-Pacific Vexillum–Austromitra–Atlantilux lineage, and has evolved independently in the Nodicostellaria–Mitromica lineage of the western hemisphere. The genera Ceratoxancus and Latiromitra are transferred from the Ptychatractidae to the Costellariidae. Tosapusia, Protoelongata, and Pusia are ranked as full genera, the latter with the three subgenera Pusia, Ebenomitra, and Vexillena. Vexillum (Costellaria) and Zierliana are treated as synonyms of Vexillum. The replacement name Suluspira is proposed for Visaya Poppe, Guillot de Suduiraut & Tagaro, 2006, non Ahyong, 2004 (Crustacea). We introduce four new genera, Alisimitra, Costapex, Turriplicifer, and Orphanopusia, and characterize their anatomy; 14 new species, mostly from deep water in the Indo-Pacific, are described in the genera Tosapusia, Alisimitra, Costapex, and Pusia. At least two species of Costapex gen. nov. have been collected from sunken wood.

Résumé [+] [-]The conoidean family Drilliidae Olsson, 1964 is a species-rich lineage of marine gastropods, showing a high degree of diversification in comparison to other families of Conoidea. Despite intensive molecular phylogenetic studies during the last decade that have led to notable rearrangements of conoidean systematics, the genus- and species-level taxonomy of Drilliidae has not thus far been affected and remains entirely based on shell features. In the current study we revisit species delimitation in a morphological cluster of species from the Indo-Pacific referred to as the Clavus canalicularis complex, using an integrative taxonomy approach. The species in the complex possess robust thick-walled shells typically over 15 mm in height with sculpture of prominent rounded nodules located at the whorl’s shoulder, sometimes sharp and squamiform, or producing long spines. We find that in addition to five known species, the complex comprises four new species. These are described as Clavus brianmayi n. sp. (New Caledonia), Clavus davidgilmouri n. sp. (the Philippines), Clavus andreolbrichi n. sp. (Vanuatu and New Ireland) and Clavus kirkhammetti n. sp. (Madagascar). Clavus exasperatus (Reeve, 1843), which was previously considered widely distributed in IndoPacific, is shown to be confined to the western Indian Ocean.

Résumé [+] [-]With about 800 Recent species, ‘miters’ are a widely distributed group of tropical and subtropical gastropods that are most diverse in the Indo-West Pacific. They include the two families Mitridae and Costellariidae, similar in shell morphology and traditionally treated as close relatives. Some genera of deep-water Ptychatractidae and Volutomitridae are close to miters in shell morphology, and the term ‘mitriform gastropods’ has been introduced to refer to Mitridae, Costellariidae, and this assortment of convergent forms. The present study aimed at the reconstruction of phylogenetic relationships of mitriform gastropods based on representative taxon sampling. Four genetic markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA mitochondrial genes, and H3 (Histone 3) nuclear gene] were sequenced for over 90 species in 20 genera, and the molecular data set was supplemented by studies of radula morphology. Our analysis recovered Mitridae as a monophyletic group, whereas the genus Mitra was found to be polyphyletic. Of 42 mitrid species included in the analysis, 37 formed a well-supported ‘core Mitridae’ consisting of four major clades, three of them consistent with the subfamilies Cylindromitrinae, Imbricariinae, and Mitrinae, and Strigatella paupercula standing out by itself. Basal to the ‘core Mitridae’ are four minor lineages, with the genus Charitodoron recognized as sister group to all other Mitridae. The deepwater family Pyramimitridae shows a sister relationship to the Mitridae, with high support for a Pyramimitridae + Mitridae clade. Our results recover the monophyly of the Costellariidae, which form a wellsupported clade that also includes Ptychatractidae, Columbariinae, and Volutomitridae, but not Mitridae. Most derived and diverse amongst Costellariidae are species of Vexillum, characterized by a bow-shaped, multicuspidate rachidian tooth. Several previously unrecognized deep-water costellariid lineages are revealed. Their members retain some plesiomorphies – in particular a tricuspidate rachidian tooth – that makes them morphologically intermediate between ptychatractids and Vexillum. The taxa of Ptychatractidae included in the analysis are not monophyletic, but form three well-supported, unrelated groupings, corresponding respectively to Ceratoxancus + Latiromitra, Exilia, and Exiliodea. None of them shows an affinity to Pseudolividae.

Résumé [+] [-]Alongside confirmation of the monophyly of the gastropod family Mitridae, a recent molecular phylogenetic analysis disclosed multiple inconsistencies with the existing taxonomic framework. In the present study, we expanded the molecular sampling to 103 species, representing 26% of the 402 extant species currently accepted in the family and 16 of the 19 currently accepted extant genera; 83 species were sequenced for four molecular markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA, and H3 (Histone 3)]. Molecular analyses were supplemented by morphological studies, focused on characters of the radula and, in a more restricted data set, proboscis anatomy. These data form the basis for a revised classification of the Mitridae. A first dichotomy divides mitrids into two unequal clades, Charitodoron and the Mitridae s.s. Species of Charitodoron show profound differences to all other Mitridae in foregut anatomy (lacking an epiproboscis) and shell morphology (smooth columella, bulbous protoconch of non-planktotrophic type), which leads to the erection of the separate family Charitodoronidae fam. nov. Three traditional subfamilies (Mitrinae, Cylindromitrinae and Imbricariinae) correspond to three of the inferred phylogenetic lineages of Mitridae s.s.; we redefine their contents, reinstate Strigatellinae Troschel, 1869 as valid and establish the new subfamily Isarinae. In the absence of molecular material, a sixth subfamily, Pleioptygmatinae, is included in Mitridae based on morphological considerations only. To resolve the polyphyly of Mitra and Cancilla in their current taxonomic extension, we reinstate the genera Episcomitra Monterosato, 1917, Isara H. & A. Adams, 1853 and Probata Sarasúa, 1989 and establish 11 new genera: Quasimitra, Roseomitra, Fusidomiporta, Profundimitra, Cancillopsis, Pseudonebularia, Gemmulimitra and Neotiara in Mitrinae; Imbricariopsis in Imbricariinae; Carinomitra and Condylomitra are left unassigned to a subfamily. Altogether 32 genera are recognized within the family. Their diversity and distribution are discussed, along with general trends in morphological evolution of the family.

Résumé [+] [-]Marine gastropods of the genus Conus are renowned for their remarkable diversity and deadly venoms. While Conus venoms are increasingly well studied for their biomedical applications, we know surprisingly little about venom composition in other lineages of Conidae. We performed comprehensive venom transcriptomic profiling for Conasprella coriolisi and Pygmaeconus traillii, first time for both respective genera. We complemented referencebased transcriptome annotation by a de novo toxin prediction guided by phylogeny, which involved transcriptomic data on two additional ‘divergent’ cone snail lineages, Profundiconus, and Californiconus. We identified toxin clusters (SSCs) shared among all or some of the four analysed genera based on the identity of the signal region—a molecular tag present in toxins. In total, 116 and 98 putative toxins represent 29 and 28 toxin gene superfamilies in Conasprella and Pygmaeconus, respectively; about quarter of these only found by semi-manual annotation of the SSCs. Two rare gene superfamilies, originally identified from fish-hunting cone snails, were detected outside Conus rather unexpectedly, so we further investigated their distribution across Conidae radiation. We demonstrate that both these, in fact, are ubiquitous in Conidae, sometimes with extremely high expression. Our findings demonstrate how a phylogeny-aware approach circumvents methodological caveats of similarity-based transcriptome annotation

Résumé [+] [-]Marginelliform gastropods are a heterogeneous and diverse group of molluscs encompassing over 1,600 living species, among which are the smallest known neogastropods. The relationships of marginelliform gastropods within the order Neogastropoda are controversial, and the monophyly of the two marginelliform families the Marginellidae J. Fleming, 1828 and the Cystiscidae Stimpson, 1865, remains unconfirmed. DNA sequence data have never been used to assess the relationships of the marginelliform gastropods, making this group the only major branch missing in our current understanding of the neogastropod tree of life. Here we report results of the first multilocus phylogenetic analysis of marginelliform gastropods, which is based on a dataset comprising 63 species (20 genera) of Marginellidae and Cystiscidae, and a wide range of neogastropod lineages. The Marginellidae and Cystiscidae form a moderately supported clade that is sister to the family Volutidae. Marginellona gigas appears to be sister to all other marginelliforms. The subfamily Marginellinae was recovered as a well-supported clade, and good resolution of this part of the tree makes it possible to propose amendments to the family-level classification of the group. The relationship between Granulina and other marginelliforms could not be resolved and requires further study. Due to poor resolution of basal relationships within the Marginellidae–Cystiscidae clade, the monophyly of the Cystiscidae was neither confirmed nor convincingly rejected. The shell morphology of most marginellid and cystiscid genera is taxonomically not very informative but, nevertheless, of the traditionally recognized genera only Gibberula and Dentimargo were shown to be polyphyletic. Although a comprehensive systematic revision of the group requires more extensive taxonomic sampling (e.g. with better representation of the type species of nominal genus-group names), our results support the superfamily Volutoidea, comprising four families (Volutidae, Cystiscidae, Marginellidae and Marginellonidae), with the placement of the Granulinidae uncertain for the time being.

Résumé [+] [-]The conoidean family Terebridae is an intriguing lineage of marine gastropods, which are of considerable interest due to their varied anatomy and complex venoms. Terebrids are abundant, easily recognizable and widely distributed in tropical and subtropical waters, but our findings have demonstrated that their systematics requires revision. Here we elaborate the classification of Terebridae based on a recently published molecular phylogeny of 154 species, plus characters of the shell and anterior alimentary system. The 407 living species of the family, including seven species described herein, are assigned to three subfamilies: Pellifroniinae new subfamily, Pervicaciinae and Terebrinae. The Pellifroniinae comprises five deep-water species in two genera, Pellifronia and Bathyterebra n. gen. Pellifroniinae possess a radula of duplex marginal teeth, well-developed proboscis and venom gland, and a very small rhynchodeal introvert. The Pervicaciinae includes c. 50 species in the predominantly Indo-Pacific genera Duplicaria and Partecosta. Pervicaciinae possess salivary glands, a radula of solid recurved marginal teeth and a weakly developed rhynchodeal introvert, but lack proboscis and venom gland. The remaining Terebridae species are classified into 15 genera in the subfamily Terebrinae (including four genera described herein); nine genera are defined on the basis of phylogenetic data and six solely on shell morphology. The Indo-Pacific genera Profunditerebra n. gen., Maculauger n. gen. and Myurellopsis n. gen. each include about a dozen species. The first is restricted to the deep waters of the Indo-West Pacific, while the latter two range widely in both geographic and bathymetric distribution. Neoterebra n. gen. encompasses about 65 species from a range of localities in the eastern Pacific, Caribbean, and Atlantic, and from varying depths. To characterize the highly diversified genera Terebra, Punctoterebra, Myurella and Duplicaria, each of which comprise several morphological clusters, we propose the use of DNA-based diagnoses. These diagnoses are combined with more informative descriptions to define most of the supraspecific taxa of Terebridae, to provide a comprehensive revision of the group.

Résumé [+] [-]A new genus and species of Fasciolariidae, Angulofusus nedae n. gen. n. sp. conchologically superficially resembling some Conoidea is described. Radula, anatomy and coloration of the body of the new species suggest that it belongs to subfamily Fusininae, being very similar in anatomy to species of the genus Amiantofusus. The species is broadly distributed in the Indo-Pacific, from the Philippines, through Vanuatu and New Caledonia to Wallis and Futuna in 40 to 105 m.

Résumé [+] [-]Conoidean gastropods of the genera Kermia, Oliver, and Pseudodaphnella Boettger, (Raphitomidae) are common in shallow-water habitats of the tropical Indo-Pacific. They form a distinct morphologically homogeneous complex, easily recognizable by sculpture and colour pattern, encompassing around 80 described species. Examination of a vast material accumulated during recent expeditions in various regions of the Indo-Pacific revealed a number of undescribed species of this complex. Our material included 32 morphospecies available for molecular phylogenetic study; phylogenetic reconstruction based on the COI gene confirmed the species hypotheses based on morphological characters. A total of 18 terminal taxa were attributed to known species and 14 were identified as new species. Of these, 12 species, for which sufficient material was available, are described. Phylogenetic analysis indicated close relationships of the genera Kermia and Pseudodaphnella with members of some other conoidean genera (specifically Exomilus Hedley, , Paramontana Laseron, and Thetidos Hedley, ) and taxonomic implications of the data obtained are discussed. To test the taxonomic value of protoconch and review its wide use in classification of Conoidea, the evolution of the protoconch morphology was reconstructed using a phylogenetic tree. It has revealed that protoconchs of different types may appear in closely related species, sometimes hardly distinguishable by teleoconch morphology. A switch from planctotrophic to non-planctotrophic mode of development occurred at least four times in the evolutionary history of the Kermia Pseudodaphnella complex, indicating high developmental plasticity of the group. Its role in radiation of the Kermia Pseudodaphnella complex and applications for use of protoconch morphology in the classification of Conoidea are discussed.

Fedosov A.E., Olivera B.M., Watkins M. & Barkalova V. 2014. A new species of Casmaria H. Adams & A. Adams, 1853 (Gastropoda, Cassidae) from the Philippines identified by molecular data. European Journal of Taxonomy 78: 1-13. DOI:10.5852/ejt.2014.78
Résumé [+] [-]The genus Casmaria H. Adams & A. Adams, 1853 (family Cassidae) is widespread in the tropical Indo-Pacific and has been documented from some Atlantic localities as well. Two Casmaria species, C. erinaceus (Linnaeus, 1758) and C. ponderosa (Gmelin, 1791), are common in Indo-Pacific shallow-water sandy bottom communities and are characterized by high morphological variability; both species encompass multiple, often sympatric forms of uncertain status. In the present study we carry out a phylogenetic analysis of some Philippine Casmaria morphs and demonstrate that one of the distinctive morphs earlier assigned to Casmaria ponderosa is in fact a different species, which we describe as Casmaria boblehmani sp. nov. The smooth form of Casmaria ponderosa, C. ponderosa ponderosa, and the solid nodulose form, widely called “form nodulosa” despite being strikingly different in shell morphology, are shown to be conspecific. Studied specimens of these two morphs even from different localities share the same haplotype of the CO1 gene. In light of these new data on the morphological variability of Casmaria species, we discuss criteria of species delimitation in the genus Casmaria and possible affinities of Casmaria boblehmani sp. nov. within the genus.

Résumé [+] [-]The triviid genus Trivellona Iredale, 1931 is distinguished from the other genera within the Triviidae and all 32 known taxa are revised. All recent available informations as weil as the original descriptions and the types were studied and resulted in the description of five species new to science: Trivellona schilderi nov. sp., Trivellona macneili nov. sp., Trivellona catei nov. sp., Trlvellona dolini nov. sp. and Trivellona globulus nov. sp. They are briefly discussed with related forms and with its congeners .. The assumed endemism of several forms of the genus to the bathyal of New Caledonia by Dolin (2001) could not be confirmed as many new findings in the deep water from the Aliguay Island and Balicasag Island, Philippines show a wider distribution th an previously thought This is also true of Trivellona eos (Roberts, 1913) and Trivellona opalina (Kuroda & Cate in Cate, 1979), which are reported for the first time in Philippines waters. The genus Willungia Powell, 1938 is attached as junior synonym to the genus Triviella Jousseaume, 1884 and the decision is briefly discussed.

Résumé [+] [-]The study of TRIVIIDAE from the Pacific and Indo-Pacific has continued since the most recent description of species from French Polynesia (Fehse & Grego, 2008). In the meantime more than 50,000 specimens have been examined and identified by the senior author. Still the archipelago causes further surprises in the genus Trivirostra. Dredgings and dive collecting by Jean Letourneux and his team brought up several dozens of new shells. Furthermore, both authors could obtain other specimens from different sources. The present study is also supported by Dr. Philippe Bouchet and the MNHN with their huge amount of dredging materials from French Polynesia besides other Indo-Pacific localities. Among the material two new species were discovered which are described as Trivirostra leylae nov. Sp. And Trivirostra matavai nov. Sp.

Résumé [+] [-]The second part of the series deals with the dredged Triviidae from Taiwan. The Triviid fauna of Taiwan is still fragmentarily known. It resembles the one of the Philippines but the deep sea fauna is still different although both are in direct neighborhood. Hereinafter one Novatrivia and five Gregoia are described as new - Novatrivia taiwanica n. sp., Gregoia yurikantori n. sp., Gregoia danielleae n. sp., Gregoia formosa n. sp., Gregoia vorago n. sp. and Gregoia aemula n. sp. These taxa could not be detected in the Philippines so far although dredgings in deep water are regularly done in the Philippines and the author could examine thousands of specimens in several collections..

Résumé [+] [-]The present study aims to fulfill the gap of taxonomic knowledge on Triphoridae from Brazil. We describe five new species (Isotriphora uncia sp. nov., Isotriphora leo sp. nov., Monophorus verecundus sp. nov., Sagenotriphora albocaput sp. nov., Similiphora lucida sp. nov.), report five species previously known only from the Caribbean and related areas (Cheirodonta dupliniana (Olsson, 1916), Eutriphora auffenbergi Rolán & Lee, 2008, Isotriphora tricingulata Rolán & Fernández-Garcés, 2015, Marshallora ostenta Rolán & Fernández-Garcés, 2008, Monophorus caracca (Dall, 1927) comb. nov.) and describe six morphotypes at the generic level (Isotriphora sp. 1, Marshallora sp. 1, Nanaphora sp. 1, Sagenotriphora sp. 1, Sagenotriphora sp. 2, Similiphora sp. 1). Remarks are made to some species previously recorded from Brazil, including the invalidation of records, problems of generic allocation and geographical range extensions. Maps of the geographical distribution are provided for the 65 currently recognized species of Triphoridae from Brazil. Of these, 31 species are endemic to Brazil and 58 inhabit the continental shelf vs only seven from the continental slope. A distinct geographical zone occurs in southeastern Brazil. A few species occur exclusively near the mouth of the Amazon River, whereas others inhabit a local biogenic reef, possibly serving as a biogeographical corridor that connects western Atlantic populations. Species of Isotriphora from Brazil are particularly common around oceanic islands, probably due to adopting intracapsular metamorphosis, which may have evolved in more than one evolutionary event.

Résumé [+] [-]In the present paper we describe the new genus Amiantofusus gen. nov. to accommodate the Atlantic species Fusus amiantus Dall, 1889. The genus belongs to Fasciolariidae and this family is confirmed as distinct from Buccinidae, based on anatomical differences. We add an Indo-West Pacific fauna of seven species described as new to science: miantofusus pacificus sp. nov. (North Fiji Basin, New Caledonia, southern Coral Sea, south West Pacific), A. gloriabundus sp. nov. (North Fiji Basin, Vitiaz Zone), A. sebalis sp. nov. (New Caledonia, Loyalty Islands, Vanuatu), A. candoris sp. nov. (Chesterfield Islands, Fairway), A. maestratii sp. nov. (New Caledonia), A. borbonica sp. nov. (Reunion) and A. cartilago sp. nov. (Mozambique Channel). In addition we add two unnamed species: A. species 1 (North Fiji Basin) and A. species 2 (Vanuatu). Fusus thielei Schepman, 1911 is briefly discussed, the generic placement is still uncertain.

Résumé [+] [-]The deep water genus Kanamarua Kuroda, 1951 is distinguished from the buccinid genus Metula H. Adams & A. Adams, 1853 on the basis of shell sculpture and protoconch morphology. The original description of the genus is translated from Japanese. We consider Kanamarua as belonging to Colubrariidae according to Okutani (2000: 500-501). Previously known only from the Indo-West Pacific, the range of the genus is extended into the West Atlantic. Kanamarua adonis (Dall, 1919) is recorded from the Tanimbar Islands (Indonesia) and off Luzon and Mindoro Islands (Philippines), extending the range to the west and the south. Kanamarua tazimai Kuroda, 1951 is reinstated as a distinct species and removed from synonymy with K. adonis, the original description is translated from Japanese. Kanamarua rehderi Kilbum, 1977 and Metula vicdani Kosuge, 1989 are senior synonyms of Kanamarua hyatinthus Shikama, 1973, the taxon is briefly discussed with special attention to its wide geographie range. The species is recorded from Vanuatu Islands, extending the range in southwestern direction. Metula boswellae Kilbum, 1975 is transferred to Kanamarua, based on conchological characteristics. Kanamarua narcissisma sp. nov. (lndonesia and Australia) and Kanamanta francroberti sp. nov. (Guadeloupe) are here described.

Résumé [+] [-]The species placed in the heterogenous genus Clivipollia Iredale, 1929 are revised. Strong similarities in apertural morphology with Falsilatirus Emerson & Moffitt, 1988 are discussed and the genus is regarded as a sister genus of Clivipollia. Differences in protoconch morphology, apertural denticulation and sculpture serve to distinguish Speccapollia gen. nov. to harbour Ricinula recurva Reeve, 1846, a species commonly assigned to Clivipollia and Clivipollia tokiae Chino & Fraussen, 2015. Engina Gray, 1839 and Enzinopsis Iredale, 1940 are briefly discussed and compared to the new genus. The new genus Minioniella gen. nov. is described for Minioniella heleneae sp. nov. and compared to Clivipollia and Enginella Monterosato, 1917. Three new species are added to the Indo-West Pacific fauna: Clivipollia delicata sp. nov. from Austral Islands (southern French Polynesia), Speccapollia africana sp. nov. from Mozambique and Minioniella heleneae sp. nov. from Moruroa (southern French Polynesia). Ricinula pulchrum Reeve, 1846 is proposed as a nomen protectum in favor of Turbinella elegans Dunker in Küster, 1844. Peristernia elegans var. papuaensis Tapparone Canefri, 1879 from New Guinea is placed in synonymy with Clivipollia pulchra (Reeve, 1846). Peristernia paulucciae Tapparone Canefri, 1879 from East Africa is confirmed as a synonym of Clivipollia incarnata Deshayes in Laborde & Linant, 1830. Turbinella wagneri Anton, 1839 is excluded from the genus Clivipollia but no alternative is proposed, its placement being still uncertain. Engina gigas Landau & Vermeij, 2012, a fossil from the early Pliocene of the Dominican Republic, is transferred to Clivipollia based on protoconch morphology and sculpture, being the only record of Clivipollia known to us in the Atlantic.

Résumé [+] [-]Two new species of the genus Calagrassor Kantor et al., 2013 are described. Calagrassor analogus n. sp. is distributed in Japan, the East China Sea and Taiwan, and has been previously confused with Aulacofusus hiranoi (Shikama, 1962). Differences in protoconch morphology serve to distinguish C. analogus n. sp. from A. hiranoi and differences in sculpture serve to distinguish this new species from C. aldermenensis (Powell, 1971) and C. hayashii (Shikama, 1971). A second and hitherto unknown species is described from Japanese waters as Calagrassor hagai n. sp. Differences in spiral and axial sculpture serve to distinguish it from other known species in the genus.

Amended generic classification of the marine gastropod family Phenacolepadidae: transitions from snails to limpets and shallow-water to deep-sea hydrothermal vents and cold seeps. Zoological Journal of the Linnean Society 185(3): 636-655. DOI:10.1093/zoolinnean/zly078
Résumé [+] [-]Benthic invertebrates at deep-sea hydrothermal vents and cold seeps have attracted considerable attention regarding their spatiotemporal distributions, colonization pathways, geological origins and morphological, ecological and physiological adaptations. Here we first reconstruct a molecular phylogeny for vent and seep species in the gastropod subclass Neritimorpha based on combined mitochondrial and nuclear gene sequences. The resulting tree, in conjunction with anatomical and palaeontological evidence, indicates that neritimorph snails and limpets in the Cenozoic deep-sea chemosynthetic habitats belong to the monophyletic subfamily Shinkailepadinae (family Phenacolepadidae). Confamilial shallow-water species form its sister clade, the subfamily Phenacolepadinae. There were probably at least three independent shifts from the coiled snail with a functional operculum to the limpet form in the evolutionary history of the family, twice in the deep-sea Shinkailepadinae and once in the shallow-water Phenacolepadinae. Physiological and ecological characteristics including the presence of red blood cells and larval migration seem to have facilitated their early Cenozoic Colonization of vents and seeps. The type specimens of type species were investigated for most nominal genera to amend generic classification of this long-neglected family. A monotypic Divia gen. nov. is proposed for ‘Shinkailepas’ briandi; Shinkailepas and Thalassonerita pre-date Olgasolaris and Bathynerita, respectively;

Résumé [+] [-]Extracting DNA from gastropods presents particular difficulties due to the capacity of the living animal to retract into the shell, resulting in poor penetration of the ethanol into the tissues. Because the shell is essential to establish the link between sequences and traditional taxonomic identity, cracking the shell to facilitate fixation is not ideal. Several methods are currently in routine use to overcome this difficulty, including chemical relaxation, drilling the shell and boiling. Most of these methods are time-consuming, may be safety hazards and constitute a bottleneck in the preparation of large numbers of specimens in the field. We have experimented with a method traditionally used to clean shells that involves placing the living gastropods in a microwave (MW) oven; the electromagnetic radiation very quickly heats both the animal and the water trapped inside the shell, resulting in separation of the muscles that anchor the animal to the shell. Done properly, the body can be removed intact from the shell and the shell voucher is preserved undamaged. To test the method, the bodies of live-collected specimens from two gastropod species were separated from their shell by microwaving and by anesthetizing/drilling. After identical extraction and PCR procedures, the gels showed no difference in DNA quantity or quality, and the resulting sequences are identical within species. The method was then implemented on a large scale during expeditions, resulting in higher percentage of DNA extraction success. The MWs are also effective for quickly and easily removing other molluscs from their shells, that is, bivalves and scaphopods. Workflows implementing the MW technique show a three- to fivefold increase in productivity compared with other methods.

Résumé [+] [-]Nassariidae are a group of scavenging, predominantly marine, snails that are diversified on soft bottoms as well as on rocky shores, and are the subject of numerous research papers in ecology, ecotoxicology or paleontology. A weak and/or apparently continuous variation in shell characters has resulted in an intimidating taxonomy, with complex synonymy lists. Over 1320 extant nominal species have been described, of which 442 are currently regarded as valid. Above species level, the state of the art is equally hazy, with four subfamilies and twelve genera currently accepted, and many other names in the graveyard of synonymy. A molecular analysis based on three mitochondrial (COI, 16S, 12S) and two nuclear (28S, H3) markers was conducted. Our dataset includes 218 putative nassariid species, comprising 9 of the 12 valid genera, and 25 nominal genera represented by their type species. The monophyly of the Nassariidae as classically construed is not confirmed. Species of Antillophos, Engoniophos, Phos, Nassaria, Tomlinia and Anentome (formerly considered Buccinidae) are included inside the Nassariidae clade. Within the Nassariinae, the tree unexpectedly demonstrates that species from the Atlantic and the Indo-Pacific form different clades which represent several independent diversification events. Through an integrative approach, the reconstruction of ancestral states was addressed for eight characters supposedly informative for taxonomy. Using numerous fossil calibration points, Nassariidae appear to have originated 120 MYA ago in Atlantic temperate waters during the Lower Cretaceous. Our results have a profound impact on nassariid taxonomy, especially with regard to the validity of subfamily- and genus-level names.

Résumé [+] [-]Trois nouvelles espèces de Muricidae ont été collectées au cours de l’expédition « La Planète Revisitée » en Guyane Française en 2014-2015. Les deux premières, Phyllonotus guyanensis n. sp. et Phyllonotus salutensis n. sp. appartiennent au genre Phyllonotus Swainson, 1833. Dans la région Atlantique Ouest, cinq espèces sont actuellement répertoriées dans ce genre : Phyllonotus pomum (Gmelin, 1791), P. oculatus (Reeve, 1845), P. margaritensis (Abbott, 1958), P. globosus Emmons, 1858 et P. whymani Petuch & Sargent, 2011. Phyllonotus guyanensis n. sp. décrit ici est comparé à deux espèces proches : P. pomum et P. whymani. Phyllonotus pomum est largement répandu de la Caroline du Nord au Nord de l’Amérique du Sud tandis que P. whymani n’est connu que de sa localité-type, Dry Tortuga, Florida Keys. La deuxième espèce, Phyllonotus salutensis n. sp., est comparée à P. margaritensis des Iles du nord-est du Venezuela, P. globosus de la presqu’île du Paraguana au nord-ouest du Venezuela et P. pomum. Murex mexicanus Petit de la Saussaye, 1852, du Golfe du Mexique, (non Murex mexicanus Stearns, 1894 = Chicoreus maurus (Broderip, 1833)) a toujours été confondu avec P. pomum. Il est ici réhabilité sous le taxon de Phyllonotus mexicanus (Petit de la Saussaye, 1852). Phyllonotus oculatus se distingue de toutes les autres espèces nommées ci-dessus par une protoconque multispirale (Houart, 1987) et n’est pas abordé ici. La troisième espèce est une Favartia Jousseaume, 1880, Favartia charlesi n. sp. Elle est comparée avec l’espèce voisine F. hidalgoi (Crosse, 1869) rencontrée du Golfe du Mexique au Sud du Brésil entre 120 et 400 m de profondeur.

Résumé [+] [-]The olive shells of the genus Amalda comprises readily recognized species of marine neogastropod mollusks found around the world. The New Zealand Amalda fauna has particular notoriety as providing one of the best demonstrations of evolutionary morphological stasis, a prerequisite for punctuated equilibrium theory. An excellent fossil record includes representation of three extant endemic Amalda species used to explore patterns of form change. However, the phylogenetic relationship of the New Zealand Amalda species and the timing of their lineage splitting have not been studied, even though these would provide valuable evidence to test predictions of punctuated equilibrium. Here, we use entire mitogenome and long nuclear rRNA gene cassette data from 11 Amalda species, selected from New Zealand and around the world in light of high rates of endemicity among extant and fossil Amalda. Our inferred phylogenies do not refute the hypothesis that New Zealand Amalda are a natural monophyletic group and therefore an appropriate example of morphological stasis. Furthermore, estimates of the timing of cladogenesis from the molecular data for the New Zealand group are compatible with the fossil record for extant species and consistent with expectations of punctuated equilibrium.

Résumé [+] [-]A new shallow water species of the lucinid bivalve Pleurolucina is described from Curaçao in the southern Caribbean Sea and compared with known species of the genus from the western Atlantic and eastern Pacific Oceans. Although confused with the Floridian species P. leucocyma, it is most similar to the eastern Pacific P. undata. As in all studied lucinids, the new species possesses symbiotic bacteria housed in the ctenidia. The shell microstructure is unusual with repeated and intercalated conchiolin layers that have sublayers of ‘tulip-shaped’ calcareous spherules. Predatory drillings by naticid gastropods frequently terminate at the conchiolin layers.

Résumé [+] [-]Predator-prey interactions are thought to play a driving role in animal evolution, especially for groups that have developed venom as their predatory strategy. However, how the diet of venomous animals influences the composition of venom arsenals remains uncertain. Two prevailing hypotheses to explain the relationship between diet and venom composition focus on prey preference and the types of compounds in venom, and a positive correlation between dietary breadth and the number of compounds in venom. Here, we examined venom complexity, phylogenetic relationship, collection depth, and biogeography of the Terebridae (auger snails) to determine if repeated innovations in terebrid foregut anatomy and venom composition correspond to diet variation. We performed the first molecular study of the diet of terebrid marine snails by metabarcoding the gut content of 71 terebrid specimens from 17 species. Our results suggest that the presence or absence of a venom gland is strongly correlated with dietary breadth. Specifically, terebrid species without a venom gland displayed greater diversity in their diet. Additionally, we propose a revision of the definition of venom complexity in conoidean snails to more accurately capture the breadth of ecological influences. These findings suggest that prey diet is an important factor in terebrid venom evolution and diversification and further investigations of other understudied organisms, like terebrids, are needed to develop robust hypotheses in this area.

Résumé [+] [-]The molluscan class Gastropoda includes over 5,000 parasitic species whose evolutionary origins remain poorly understood. Marine snails of the genus Caledoniella (Caledoniellidae) are obligate parasites that live on the abdominal surface of the gonodactylid mantis shrimps. They have highly modified morphological characteristics specialized to the ectoparasitic lifestyle that make it difficult to infer their close relatives, thereby posing a question about their current systematic position in the superfamily Vanikoroidea. In the present study, we performed molecular phylogenetic analyses using three nuclear and three mitochondrial gene sequences to unveil the phylogenetic position of these enigmatic snails. The resulting trees recovered Caledoniella in the su perfamily Truncatelloidea and within a subclade of commensal species that live on the burrow wall of marine benthic invertebrates. More specifically, Caledoniella formed the sister clade to a commensal snail species living in mantis-shrimp burrows and they collectively were sister to Sigaretornus planus (formerly in the family Tornidae or Vitrinellidae), a commensal living in echiuran burrows. This topology suggests that the species of Caledoniella achieved their ectoparasitic mode of life through the following evolutionary pathway: (1) invasion into the burrows of benthic invertebrates, (2) specialization to mantis shrimps, and (3) colonization of the host body surface from the host burrow wall with the evolution of the parasitic nature. The final step is likely to have been accompanied by the acquisition of a sucker on the metapodium, the loss of the radula and operculum, and the formation of monogamous pair bonds. The present molecular phylogeny also suggested parallel evolution of planispiral shells in a subclade of Truncatelloidea and enabled us to newly redefine the families Caledoniellidae, Elachisinidae, Teinostomatidae, Tornidae and Vitrinellidae.

Résumé [+] [-]Many marine species are specialized to specific parts of a habitat. In a mangrove forest, for instance, species may be restricted to the mud surface, the roots and trunks of mangrove trees, or rotting logs, which can be regarded as distinct microhabitats. Shifts to new microhabitats may be an important driver of sympatric speciation. However, the evolutionary history of these shifts is still poorly understood in most groups of marine organisms, because it requires a well-supported phylogeny with relatively complete taxon sampling. Onchidiid slugs are an ideal case study for the evolutionary history of habitat and microhabitat shifts because onchidiid species are specialized to different tidal zones and microhabitats in mangrove forests and rocky shores, and the taxonomy of the family in the Indo-West Pacific has been recently revised in a series of monographs. Here, DNA sequences for onchidiid species from the North and East Pacific, the Caribbean, and the Atlantic are used to reconstruct phylogenetic relationships among Onchidella species, and are combined with new data for Indo-West Pacific species to reconstruct a global phylogeny of the family. The phylogenetic relationships of onchidiid slugs are reconstructed based on three mitochondrial markers (COI, 12S, 16S) and three nuclear markers (28S, ITS2, H3) and nearly complete taxon sampling (all 13 genera and 62 of the 67 species). The highly-supported phylogeny presented here suggests that ancestral onchidiids most likely lived in the rocky intertidal, and that a lineage restricted to the tropical Indo-West Pacific colonized new habitats, including mudflats, mangrove forests, and high-elevation rainforests. Many onchidiid species in the Indo-West Pacific diverged during the Miocene, around the same time that a high diversity of mangrove plants appears in the fossil record, while divergence among Onchidella species occurred earlier, likely beginning in the Eocene. It is demonstrated that ecological specialization to microhabitats underlies the divergence between onchidiid genera, as well as the diversification through sym patric speciation in the genera Wallaconchis and Platevindex. The geographic distributions of onchidiid species also indicate that allopatric speciation played a key role in the diversification of several genera, especially Onchidella and Peronia. The evolutionary history of several morphological traits (penial gland, rectal gland, dorsal eyes, intestinal loops) is examined in relation to habitat and microhabitat evolutionary transitions and suggests that the rectal gland of onchidiids is an adaptation to high intertidal and terrestrial habitats.

Résumé [+] [-]Bivalves belonging to the genera Idas and Adipicola were collected from wood fall environments in the west Pacific (Vanuatu islands) between 300 and 890 m depths in 2004. Bacterial symbionts were checked by three complementary techniques: histological and DAPI staining, in situ hybridization (FISH), and TEM. No bacteria were detected inside the gills of the two species, rejecting the endosymbiosis hypothesis. However, results from our study demonstrated the existence of ectosymbionts colonizing microvilli differentiated at the apical surface of the cells constituting the lateral zone of gill filaments. These ectosymbionts are gamma-Proteobacteria due to their strong hybridization with the specific probe GAM42; in contrast no hybridization was obtained from either gills or other host tissues by using the oligonucleotide probes specific to alpha- beta- and delta-Proteobacteria. Based on TEM observations, these Gram-negative bacterial symbionts are not methanotrophic due to the lack of concentric stacking of intracellular membranes in their cytoplasm. Such ectosymbionts may represent thioautotrophic bacteria as already described in various Mytilidae from hydrothermal vents and cold seeps. Unfortunately, no phylogenetic analysis could be done in this study to compare their DNA sequence to that of other marine invertebrate symbionts described to date.

Deep Sea Research Part I: Oceanographic Research Papers 64: 86-103. DOI:10.1016/j.dsr.2012.02.002
Résumé [+] [-]The increasing number of bathymodiolin mussel species being described from deep-sea chemosynthetic environments worldwide has raised many questions about their evolutionary history, and their systematics is still being debated. Mussels are also abundant in fossil chemosynthetic assemblages, but their identification is problematic due to conservative shell morphology within the group and preservation issues. Potential resolution of bathymodiolin taxonomy requires new character sets, including morphological features that are likely to be preserved in fossil specimens.

Résumé [+] [-]A number of fusinids from the Indo-Pacific deep-water fauna are studied to get more insight in the distribution and variability. The subgenus Chryseofusus (Gastropoda: Fasciolariidae: Fusinus Rafinesque, 1815) is described as new to accommodate a number of species sharing conchological characteristics different from typical Fusinus. Their separation from Fusinus s.s. is based on differences in axial sculpture (usually absent on body whorl), spiral sculpture (weak, close-set, regular, crossed by distinct growth lines), shape (shorter spire, shorter siphonal canal, less convex whorls with subsutural concavity, less constricted suture) and parietal callus (inner lip smooth, parietal wall covered with an extended, adherent thin layer as callus). Fusinus (Chryseofusus) bradneri (Drivas and Jay, 1990), F. (C.) chrysodomoides (Schepman, 1911), F. (C.) graciliformis (Sowerby, 1880), F. (C.) hyphalus M. Smith, 1940, F. (C.) jurgeni Hadorn and Fraussen, 2002, F. (C.) kazdailisi Fraussen and Hadorn, 2000 and F. (C.) subangulatus (von Martens, 1901) are briefly described and their taxonomic placement in the new subgenus is discussed. To avoid further taxonomic complications, a lectotype is designated for the correct F. (C.) chrysodomoides. F. (C.) acherius (west Madagascar, Mozambique Channel, 1475-1530 m), F. (C.) alisae (north New Caledonia, 444-452 m), F. (C.) artutus (Philippines, Bohol, deep water), F. (C.) cadus (south New Caledonia, 460-470 m), F. (C.) dapsilis (Vietnam, deep water), F. (C.) riscus (New Caledonia, Norfolk Ridge, 394-401 m), F. (C.) scissus (south New Caledonia, 535 m), F. (C.) wareni ( New Caledonia, 480 m), and F. (C.) westralis (northwest Australia, off Port Hedland, 450 m) are described as new to science.

Résumé [+] [-]The genus Granulifusus is distributed over the upper continental shelves in the Indo-West Pacific. The 27 species (21 Recent, 6 fossil) are characterized and separated from Fusinus by a granulated surface sculpture, the Recent also by a small round operculum which does not fill the aperture. Fusus (Sipho) libratus Watson 1886 and Latirus staminatus Garrard 1966 are placed in Granulifusus, their transfer based on the above mentioned conchological characteristics and on radular evidence. Granulifusus niponicus (E.A. Smith 1879), G. kiranus Shuto 1958, G. rubrolineatus (Sowerby II 1870), G. staminatus (Garrard 1966) and G. libratus (Watson 1886) were collected during the Musorstom expeditions and the material is extensively reported on. G. bacciballus sp. nov. (North New Caledonia, 444-452 m), G. benjamini sp. nov. (Coral Sea, Chesterfield, 400 m), G. balbus sp. nov. (South New Caledonia, 470 m), G. amoenus sp. nov. (Vanuatu, 480-544 m), G. geometricus sp. nov. (Tonga Islands, 427-436 m), G. monsecourorum sp. nov. (Madagascar, 240 m) and G. babae sp. nov. (Indonesia, Tanimbar Islands, 206-210 m) were also collected by the Musorstom expeditions and are added to this fauna and described as new species. From the collection of the Australian Museum, Sydney (AMS), one additional Recent species (G. lochi sp. nov., Western Australia, 301-310 m) and one fossil species (G. nakasiensis sp. nov., Nakasi Sandstone Beds, Late Pliocene, Fiji) are described. Lots of the remaining 8 species are studied with the exception of G. captivus (E.A. Smith 1899). The remaining 5 fossil species are listed and compared. G. rufinodis (Von Martens 1901) is tentatively regarded as a distinct species and a lectotype is selected.

Résumé [+] [-]Jouannetia (Pholadopsis) spinosa n. sp. is described as the second species in the West Pacific and the sixth species of the subgenus Pholadopsis. It lives in weakly consolidated mud and sand blocks obtained from relatively deep waters in Japan and the Philippines. J. (P.) spinosa n. sp. is characterized by a small spherical shell with dense spiny sculpture, remarkably concave posterior portion of the anterior slope, a siphonoplax with claw-like spines on the posterior margin, and red pigmentation on the translucent mantle collar at the base of the siphon. It bas been collected from depths ranging from 50 to 180 m, and shows a marked difference in depth range compared to the intertidal congener Jouannetia (Pholadopsis) globulosa in the West Pacific. The structure of the mesoplax in the subfamily Jouannetiinae is also discussed in detail.

Résumé [+] [-]The deep-sea malacofauna of temperate Australia remains comparatively poorly known. However, a recent influx of DNA-suitable material obtained from a series of deep-sea cruises has facilitated integrative taxonomic study on the Conoidea (Caenogastropoda : Neogastropoda). Building on a recent molecular phylogeny of the conoidean family Raphitomidae, this study focussed on the genera Gladiobela and Pagodibela (both Criscione, Hallan, Puillandre & Fedosov, 2020). We subjected a representative mtDNA cox1 dataset of deep-sea raphitomids to ABGD, which recognised 14 primary species hypotheses (PSHs), 9 of which were converted to secondary species hypotheses (SSHs). Following the additional examination of the shell and hypodermic radula features, as well as consideration of bathymetric and geographic data, seven of these SSHs were recognised as new to science and given full species rank. Subsequently, systematic descriptions are provided herein. Of these, five are attributed to Gladiobela (three of which are endemic to Australia and two more widely distributed) and two are placed in Pagodibela (one endemic to southern Australia and one widespread in the Pacific). The rarity of many ‘turrids’ reported in previous studies is confirmed herein, as particularly indicated by highly disjunct geographic records for two taxa. Additionally, several of the studied taxa exhibit wide Indo-Pacific distributions, suggesting that wide geographic ranges in deep-sea ‘turrids’ may be more common than previously assumed. Finally, impediments to deep-sea ‘turrid’ taxonomy in light of such comparative rarity and unexpectedly wide distributions are discussed.

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification. Frontiers in Marine Science 8: 749078. DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

A subsequent closer examination of the Solenogastres revealed another type of object also curled around the gorgonians, which strongly resembled Solenogastres but lacked their external features. These objects proved to be cocoons with egg capsules, each containing two eggs or young larvae, typical of the parasitic platyhelminth group Fecampiida.

Résumé [+] [-]Costapex baldwinae, new species, is described from deep reef habitats of the southern and eastern Caribbean Sea, including Curac¸ao, Dominica and Guadeloupe, where it occurs at bathyal depths on sunken wood. It is assigned to the genus Costapex based on phylogenetic analyses using partial sequences of COI, 12S and 16S mitochondrial genes that reveal it to be the sister species of two Indo-Pacific members of this genus. This new species most closely resembles Costapex martinorum (Cernohorsky, 1986) from the Philippines, but differs in being smaller, and in having a slightly lower spire and more prominently beaded spiral sculpture. Of the Caribbean species of costellariids, it is somewhat similar to Nodicostellaria laterculata (Sowerby II, 1874), which occurs in shallower water and has a white or tan rather than dark brown shell, and also a taller spire, more prominent axial sculpture, and a more rounded aperture. It differs from Vexillum styria (Dall, 1889), with which it co-occurs, in having a broader shell with a lower spire, prosocline rather than opisthocline axial ribs, and more prominent, strongly beaded spiral cords. Costapex baldwinae differs from both these taxa in having rachidian teeth with three cusps rather than five cusps (N. laterculata) or seven cusps (V. styria). The genus Costapex was previously known only from IndoPacific species. The discovery of this new species represents a significant expansion of the range of this genus into the Caribbean Sea.

Résumé [+] [-]The anatomy of representatives of the ctenoglossate deep-water limpet genus Kaiparapelta is described on the basis of new material from the Marquesas Archipelago. The anatomy is visualized by interactive 3D-reconstructions, and histological details are depicted from serial semithin and histological sections. Vetigastropod plesiomorphies are represented by papillate cephalic tentacles, by the presence of gillpockets (bursicles), by a papillate left excretory organ and a ramifying right excretory organ, by eggs with a vitelline layer and by statocysts with statoconia. The type of protoconch (of Kaiparapelta askewi), the limpet-shaped shell without juvenile coiling, the gill type and the conditions of the gonopericardial cavities are typical lepetelloidean characteristics. Kaiparapelta and other lepetelloidean genera (in particular Osteopelta, Cocculinella and Addisonia) share several apomorphic similarities: a snout with terminal mouth opening that lacks oral lappets and jaws, modification of the anterior oesophagus and separation of the gonoduct from the right excretory organ. Autapomorphies of Kaiparapelta are the huge head, a shell muscle consisting of two separate portions, a unique type of alimentary tract (ctenoglossate-like radula and hypertrophied, huge buccal apparatus with uniquely shaped cartilages, many openings of the midgut glands into the stomach, short intestine and rectum that passes outside the pericardium) and a quite concentrated anterior nervous system similar to that of Osteopelta. Kaiparapelta has been classified among the Pseudococculinidae, but molecular data have recently revealed this family to be a nonmonophyletic group. Accordingly, the exact phylogenetic position of Kaiparapelta among Lepetelloidea awaits resolution by further molecular studies.

Molecular phylogenetics and historical biogeography amid shifting continents in the cockles and giant clams (Bivalvia: Cardiidae). Molecular Phylogenetics and Evolution 93: 94-106. DOI:10.1016/j.ympev.2015.07.013
Résumé [+] [-]Reconstructing historical biogeography of the marine realm is complicated by indistinct barriers and, over deeper time scales, a dynamic landscape shaped by plate tectonics. Here we present the most extensive examination of model-based historical biogeography among marine invertebrates to date. We conducted the largest phylogenetic and molecular clock analyses to date for the bivalve family Cardiidae (cockles and giant clams) with three unlinked loci for 110 species representing 37 of the 50 genera. Ancestral ranges were reconstructed using the dispersal–extinction–cladogenesis (DEC) method with a time-stratified paleogeographic model wherein dispersal rates varied with shifting tectonics. Results were compared to previous classifications and the extensive paleontological record. Six of the eight prior subfamily groupings were found to be para- or polyphyletic. Cardiidae originated and subsequently diversified in the tropical Indo-Pacific starting in the Late Triassic. Eastern Atlantic species were mainly derived from the tropical Indo-Mediterranean region via the Tethys Sea. In contrast, the western Atlantic fauna was derived from Indo-Pacific clades. Our phylogenetic results demonstrated greater concordance with geography than did previous phylogenies based on morphology. Time-stratifying the DEC reconstruction improved the fit and was highly consistent with paleo-ocean currents and paleogeography. Lastly, combining molecular phylogenetics with a rich and well-documented fossil record allowed us to test the accuracy and precision of biogeographic range reconstructions.

Résumé [+] [-]The "Tropical Deep-Sea Benthos" program organized by IRD and MNHN has explored deep sea regions of the South Pacific for the past 30 years. Different regions of French Polynesia were examined during the cruises MUSORSTOM 9 (1997) to the Marquesa Islands, BENTHAUS (2002) to the Austral Islands and TARASOC (2009) to the Tuamotus and Society Islands. In 2009 TRONDLE & BOUTET investigated shells found during the first two mentioncd cruises along with other material for their paper "Inventory of Marine Molluscs of French Polynesia" which listed species new to science. The first three species of the Mitridae family described from those cruises belong to the subfamily Imbricariinae (HERRMANN & SALISBURY, 2012). In the present paper, three additional species of the Mitridae are described. These species are assigned to different genera because of their shell characteristics. Animals of these deep-sea species are not known to us.

Patrimoine naturelle 70:369-372, ISBN:978-2-85653-627-8
Résumé [+] [-]The centre of marine maximum marine biodiversity has become increasingly important as a means to draw attention to the conservation of coral reefs. Due to its shape, it has been named the Coral Triangle, which is supposed to encompass all or some of the reefs of the Philippines, Malaysia, Indonesia, Timor-Leste, Papua New Guinea, and the Solomon Islands. The criteria used to define this diversity centre as it is presently recognized, are based on high numbers of species recorded from within this centre. However, data within and, especially, from outside the centre's hypothetical boundaries are far from complete due to insufficient sampling. Ideally, study areas should be surveyed by the same scientits using the same methods for reaching any conclusions regarding their position in or outside the centre of maximum marine biodiversity.

Résumé [+] [-]Toxoglossate marine gastropods, traditionally assigned to the families Conidae, Terebridae, and Turridae, are one of the most populous animal groups that use venom to capture their prey. These marine animals are generally characterized by a venom apparatus that consists of a muscular venom bulb and a tubular venom gland. The toxoglossan radula, often compared with a hypodermic needle for its use as a conduit to inject toxins into prey, is considered a major anatomical breakthrough that assisted in the successful initial radiation of these animals in the Cretaceous and early Tertiary. The pharmacological success of toxins from cone snails has made this group a star among biochemists and neuroscientists, but very little is known about toxins from the other Toxoglossa, and the phylogeny of these families is largely in doubt. Here we report the first molecular phylogeny for the Terebridae and use the results to infer the evolution of the venom apparatus for this group. Our findings indicate that most of the genera of terebrids are polyphyletic, and one species ("Terebra" (s.l.) jungi) is the sister group to all other terebrids. Molecular analyses combined with mapping of venom apparatus morphology indicate that the Terebridae have lost the venom apparatus at least twice during their evolution. Species in the genera Terebra and Hastula have the typical venom apparatus found in most toxoglossate gastropods, but all other terebrid species do not. For venomous organisms, the dual analysis of molecular phylogeny and toxin function is an instructive combination for unraveling the larger questions of phylogeny and speciation. The results presented here suggest a paradigm shift in the current understanding of terebrid evolution, while presenting a road map for discovering novel terebrid toxins, a largely unexplored resource for biomedical research and potential therapeutic drug development.

Houart R. 1983. Three New Tropical Muricacean species (Gastropoda: Muricidae). Venus 42(1): 26-33
Résumé [+] [-]Since 1976, when Radwin and D'Attilio's "Murex Shells of the World" and Ruth H. Fair's "Murex Book" were published, a number of new muricid species have come to light. The lists of these are found in "La Conchiglia" no 144-145 (1981: 6-10), and 148-149 (1981: 16-17), although even this is not complete, as other species have been described since then. Three additional new species are here described: Chicoreus (Chicoreus) boucheti n. sp. was dredged by the R/V "Vauban" in New Caledonia. It may be surprising to find such a species, related to some Australian forms, in that region, but the same dredging brought such unusual species as Takia infrons E. H. Vokes, 1974 (a Japanese species); Chicoreus (Siratus) pliciferoides (Kuroda, 1942) (another Japanese species) and Murex (Murex) cf. macgllivrayi (an Australian species). These species have never been recorded in New Caledonian waters. Chicoreus (Chicoreus) paini n. sp. was illustrated by Alan Hinton in his "Guide to the Shells of Papua New Guinea" (1980: 26, fig. 11) as Chicoreus sp. It is related to the Australian Chicoreus (Chicoreus) trivialis A. Adams. AspeUa vokesiana from Madagascar is relatively different from all other AspeUa species; however, it is here compared with two more or less related forms: Aspella producta (Pease) and Aspella mauritiana Radwin and D'Attilio.

Résumé [+] [-]The genus Chicoreus Montfort, 1810 is divided into five subgenera : Chicoreus (s.s.) ; Triplex Perry, 1810, Siratus Jousseaume, 1880, Rhizophorimurex Oyama, 1950, and Chicopinnatus n. subgen. Naquetia Jousseaume, 1880 and Chicomurex Arakawa, 1964 are treated as separate genera, due to differences in radula morphology. A new subgenus of Chicoreus, Chicopinnatus is introduced for three species formerly classified in the genus Pterynotus Swainson, 1833. All of the species are systematically revised and illustrated. The Recent species are redescribed and their distributions are mapped. Sixty-three Recent species and one subspecies are recognized : 7 are referable to Chicoreus (s.s.), 39 to Triplex, 2 to Siratus, 1 to Rhizophorimurex, 3 to Chicopinnatus, 5 to Naquetia, and 7 to Chicomurex. One new species is named : Chicomurex protoglobosus. Of the 19 fossil species, 17 are assigned to Triplex and 2 to Chicomurex.

Résumé [+] [-]A species of (?)Poirieria (Pazinotus) from the New Caledonian region, recently collected by the Museum National d'Histoire Naturelle, Paris, was compared with the holotype of Latiaxis sibogae Schepman, 1911, stored in the Zoological Museum of the University of Amsterdam (Netherlands). Except for the apertural lip which is juvenile, thin and fragile in the holotype, all other shell features could be carefully compared. Spiral and axial sculpture, spines, siphonal canal and white colour are identical in the specimens from New Caledonia and in the holotype of L. sibogae. The protoconch is broken in all specimens including the holotype' but remaining fragments suggest it is paucispiral.

Résumé [+] [-]Twenty-four species of Muricidae are reviewed, 15 assigned to Chicomurex Arakawa, 1964 and 9 to Naquetia Jousseaume, 1880, two closely related genera. Each species is listed with the author's name(s), the date of description, the synonymy, the chresonymy, the distribution, the description and some comments; the chresonymy is only cited for misidentified figures in recent publications dealing with Muricidae. Each species is illustrated in colour with many specimens, while scanning electron micrographs are provided for the radulae. Photos of the protoconch are provided for most of the species as well as the spiral cord morphology. The type locality and the type material (holotype only) are noted for each name. In addition, a molecular phylogeny of Chicomurex is reconstructed from eight species using three mitochondrial genes (cytochrome oxidase c subunit I, 12S rRNA, and 16S rRNA). The phylogeny revealed three wellsupported clades within the monophyletic Chicomurex, the grouping of species being congruent with morphology (C. laciniatus complex, C. superbus complex, and C. gloriosus complex). Species sampled includes three recently described species C. lani Houart, Moe & Chen, 2014, C. globus Houart, Moe & Chen, 2015, and C. pseudosuperbus Houart, Moe & Chen, 2015; the specific status of these were assessed and found to be supported by genetic data.

Houart r. 1985. Nipponotrophon makassarensis, a new recently dredged Muricidae species of strange generic affinities (Gastropoda: Muricidae). Marine Research in Indonesia 24(1985): 83-87
Résumé [+] [-]A murieid, dredged by the French-Indonesian "CORINDON" expedition (1980) in the Strait of Makassar was recently brought to my attention. After carefully checking in the literatures, it appears to be new, but one problem was remaining unresolved: its classification in an appropriate genus. The most important points or indicators for a subfamilial or generic placement for Muricidae are: the general outline of the shell, the oper-culum and radular characteristics. The shell of Nipponotrophon makassarensis shows some affinities with the ocinebrine subgenus Ocinebrellus Jousseaume 1880 (Type sp. By O.D. Murex eurypteron Reeve 1845). General form, length, winged varices…….Unfortunately, the open canal, the typical muricine operculum and' the radula lead me to consider this genus and subfamily as not valid for the new species. The shell shows also some affinities with the genus Pterynotus Swainson 1833 (Type sp. By S.D.: Murex pinnatus Swainson 1822). However, the Pterynotus species bears always 3 varices (except for some species, questionably put in that genus, a.o. Pt. Martinetana (Roding 1798) but those have a typical dentate aperture and no winged varices), which leads us once more far away from the new species. Another possible genus might be the trophonine Trophon Montfort, 1810 (Type sp. By O.D.: Trophon magellanicus Gmelin 1791). This seemed to be the best location for our species but the operculum and the winged varices are not typical for Trophon, species.

Résumé [+] [-]The Ergalataxinae dredged during the MNHN-ORSTOM cruises in the New Caledonia region are listed and discussed (19 species of which 4 are new). Thirteen new species are described: Ergalatax zebra from the Gulf of Aden, Cytharomorula danigoi and Cytharomorula pinguis from the New Caledonia region, Cytharomorula springsteeni from the Philippine Islands, Daphnellopsis hypselos from East Sumatra, Lataxiena habropenos from Mozambique, Orania adiastolos from the New Caledonia region and South Africa, Orania archaea from the Philippine Islands, Taiwan, New Caledonia and Christmas Island (Indian Ocean), Orania dharmai from Indonesia, Orania mixta from the Philippine Islands and Sumatra, Orania ornamentata from southern Africa, Orania simonetae from the Marquesas Islands, and Orania taeniata from Christmas Island (Indian Ocean). Fusus imbricatus E. A. Smith, 1876 (not F. imbricatus Lesson, 1842 nec F. imbricatus De Kay, 1843) is renamed Lataxiena desserti. Two new combinations are adopted, Orania fischeriana (Tapparone Canefri, 1882) and Orania pacifica (Nakayama, 1988). Two nominal species are newly synonymised: Columbella clathra Lesson, 1842 is synonymised with Muricodrupa fenestrata (De Blainville, 1832) and Murex muriformis Lesson, 1844 is synonymised with Muricodrupa fiscella (Gmelin, 1791).

Résumé [+] [-]The dangers of making broad paleobiological inferences from shell morphology, based on limited observations of a few taxa, are indicated using as examples the secondary protoconchs of Colina species (Cerithiidae), and the ratchet sculpture of some surface dwelling species of Cerithium. Secondary protoconchs are not indicative of types of development and ratchet sculpture does not always indicate burrowing.

Résumé [+] [-]Members of the gastropod superfamily Stromboidea (Littorinimorpha) are characterised by their elaborate shell morphologies, distinctive mode of locomotion, and often large and colourful eyes. This iconic group comprises over 130 species, including many large and charismatic species. The family Strombidae is of particular interest, largely due to its commercial importance and wide distribution in tropical and subtropical waters. Although a few strombid mitochondrial genomes have been sequenced, data for the other four Recent families in Strom boidea are lacking. In this study we report seven new stromboid mitogenomes obtained from transcriptomic and genomic data, with taxonomic representation from each Recent stromboid family, including the first mitoge nomes for Aporrhaidae, Rostellariidae, Seraphsidae and Struthiolariidae. We also report a new mitogenome for the family Xenophoridae. We use these data, along with published sequences, to investigate the relationships among these and other caenogastropod groups. All analyses undertaken in this study support monophyly of Stromboidea as redefined here to include Xenophoridae, a finding consistent with morphological and behav ioural data. Consistent with previous morphological and molecular analyses, including those based on mitoge nomes, monophyly of Hypsogastropoda is confirmed but monophyly of Littorinimorpha is again rejected.

Résumé [+] [-]Bayesian and maximum-likelihood phylogenies of Vetigastropoda (Mollusca: Gastropoda) were reconstructed by separate and combined analyses of one mitochondrial (cytochrome oxidase I, COI) and two nuclear (histone H3 and 18S rRNA) gene sequences, with an emphasis on dense taxonomic sampling. More than 70 vetigastropod species belonging to 13 families and 25 subfamilies constituted a robust clade against the two outgroup clades Neomphalina and Cocculinoidea. The phylogenetically controversial family Seguenziidae appeared as a derived Vetigastropoda and constituted a highly supported clade with eucycline and cataegine trochids, and three skeneimorphs (Adeuomphalus, Ventsia and Xyloskenea). These taxa herein treated as the superfamily Seguenzioidea are morphologically very diverse and grouped only by the combination of symplesiomorphies in the shell, radular and head-foot characters. Anatomical peculiarities of Seguenziidae, including the presence of the penis and seminal receptacle, are all apomorphic conditions independently derived from those in higher gastropod clades, as a consequence of the small size and in response to deep-sea habitats, where sperm storage seems to be especially beneficial with low numerical density of individuals and limited periodic cues for gametogenesis. Indeed, internal or semi-internal fertilization has been evolved at least six times in Vetigastropoda, essentially in deep-sea lineages, with weak phylogenetic constraints. Other new vetigastropod clades with high support values include: Turbinidae + Tegulinae (Trochidae) + Skeneidae s.s., Clypeosectidae + Lepetodrilidae, Anatominae (Scissurellidae) + Bathyxylophila (Skeneidae) and Lepetodriloidea + Scissurellidae + Bathyxylophila.

Résumé [+] [-]Adeuomphalus Seguenza, 1876 is a little known genus among the skeneimorph vetigastropods, with very few specimens previously reported alive from the deep sea. We examined newly collected and museum-stored specimens from upper to lower bathyal depths in the Atlantic, Mediterranean, Pacific and Indian Oceans and recognize seven recent species in the genus: A. ammoniformis Seguenza, 1876, A. densicostatus (Jeffreys, 1884), A. trochanter Waren & Bouchet, 2001, A. sinuosus (Sykes, 1925) n. comb., A. guillei n. sp., A. elegans n. sp. and A. collinsi n. sp., along with a fossil species, A. bandeli (Schroder, 1995) from the Lower Cretaceous, Poland. These species are characterized by a minute and colourless shell with almost perfectly planispiral whorls, an orthocline aperture, distinct radial ribs and a deeply concave apex and base. At least three species are confirmed to be radula-less, while A. guillei n. sp. has a simplified (3 2 1 2 3) rhipidoglossate radula. Anatomical investigations of A. collinsi n. sp. and A. trochanter revealed the following traits: a monopectinate ctenidium, blunt and tapering cephalic tentacles with sensory papillae, a cylindrical snout, a simple right neck lobe, a large foot with the anterior corners drawn out into finger-like projections, a smooth ESO-tentacle and a single, micropapillate epipodial tentacle on each side of the foot; absence of pigmented eyes, eye lobes, cephalic lappets and subocular peduncles. Three species collected by submersibles in the vicinity of hydrothermal vents co-occurred with carnivorous sponges of the family Cladorhizidae; a parasitic mode of life is suggested based on the lack of the radula and the peculiar, tube-like shape of the snout. Separate and combined phylogenetic analyses of mitochondrial (COI and 16S rRNA) and nuclear (histone H3 and 18S rRNA) gene sequences revealed six monophyletic groups in Seguenzioidea: Seguenziidae, Chilodontidae, Calliotropidae, Cataegidae, Spinicalliotropis and skeneimorph seguenzioids. Three included skeneimorphs (A. elegans n. sp., Xyloskenea sp. and Ventsia tricarinata) were ambiguously grouped together with long branches and low statistical supports, possibly suggesting a vast, undiscovered phylogenetic diversity of the group. Taxonomic composition, morphological characteristics and evolutionary history are discussed for the skeneimorphs and five other groups in the superfamily.

Résumé [+] [-]Here we report our direct observation in Papua New Guinea (PNG) of three estuarine species of neritid gastropods (Neritimorpha: Neritidae) that survived on driftwood in seawater for some extended period and were transported several kilometres to a fully marine shore. Furthermore, we found another species of typically estuarine Neritidae on sunken pieces of wood at depths of 105–135 m in Vanuatu, South Pacific. These supposedly non marine gastropods evidently have the potential to survive in fully marine conditions and to disperse as benthic adults and eggs. We suggest that driftwood from shallow-water environments, including estuaries, mangrove swamps and mudflats, might have an evolutionary significance for the establishment of the sunken-wood community and possibly other chemosynthetic faunas in the deep sea.

Résumé [+] [-]The gastropod superfamily Lepetelloidea represents an extremely diverse lineage in terms of their utilization of different deep-sea organic substrates that include sunken wood, leaves, whale and fish bones, egg cases of sharks and rays, annelid tubes and detrital cephalopod beaks among others. They also inhabit cold seeps and hydrothermal vents, thus presenting an interesting case for the evaluation of such organic substrates as ‘stepping stones’ into these chemosynthetically nourished environments. Here we show the first molecular phylogeny of the Pseudococculinidae, a primarily wood-dwelling family and the most speciose in Lepetelloidea. Special emphasis is placed on the genus Caymanabyssia, for which the only subfamily Caymanabyssiinae has been established, and a new species Caymanabyssia solis is described herein and compared with previously known taxa in order to reconsider the morphological characteristics of lepetelloids on wood. Bayesian and likelihood trees reconstructed using fourgene sequences reveal that Pseudococculinidae sensu auctt. is a polyphyletic taxon that is grouped by shared plesiomorphic conditions of characters including the radula, a digestive organ, the morphology of which is often governed strongly by diet and feeding ecology. The newly reinterpreted families Pseudococculinidae and Caymanabyssiidae represent reciprocal sister clades as a basal radiation in Lepetelloidea. Sunken wood might thus have served as an ancestral habitat from which species on other substrates and vent and seep taxa were derived.

Résumé [+] [-]The superfamily Olivoidea is broadly distributed in the world’s oceans mostly in coastal waters at tropical and subtropical latitudes. It encompasses around 30 Recent genera and 460 species. Two families – Olividae and Olivellidae – are classically recognized within the superfamily. Their shell is very characteristic due to the presence of a modified callused anterior end and a fasciole. Prior to the present work, neither the monophyly of the superfamily nor the relationships among its genera had been tested with molecular phylogenetics. Four genetic markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA mitochondrial genes, and Histone 3 (H3) nuclear gene] were sequenced for 42 species in 14 genera. Additionally, 18 species were sequenced for COI only. The molecular dataset was supplemented by anatomical and radula data. Our analysis recovered, albeit with weak support, a monophyletic Olivoidea, which in turn includes with 100% support, in addition to traditional olivoideans, representatives of a paraphyletic Pseudolividae. The relationships between the former families and subfamilies are drastically revised and a new classification of the superfamily is here proposed, now including five families: Bellolividae fam. nov., Benthobiidae fam. nov., Olividae, Pseudolividae and Ancillariidae. Within Olividae four subfamilies are recognized, reflecting the high morphological disparity within the family: Olivinae, Olivellinae, Agaroniinae and Calyptolivinae subfam. nov. All the recent genera are discussed and reclassified based on molecular phylogeny and/or morphology and anatomy. The homology of different features of the shells is established for the first time throughout the superfamily, and a refined terminology is proposed. Based on a correlation between anatomical characteristics and shell features and observations of live animals, we make hypotheses on which part of the mantle is responsible for depositing which callused feature of the shell. Our results demonstrate that morphological data alone should be used with caution for phylogenetic reconstructions. For instance, the radula – that is otherwise considered to be of fundamental importance in the taxonomy of Neogastropoda – is extremely variable within the single family Olividae, with a range of variation larger than within the rest of the entire superfamily. In the refined classification, Pseudolividae are nested within Olivoidea, which is partially returning to ‘the roots’, that is to the classification of Thiele (1929).

Résumé [+] [-]In the course of preparation of a new molecular phylogeny of Conoidea based on exon-capture some new species and species with notable morphology were revealed. The taxonomy of these species is discussed and the radula of most of them illustrated for the first time. New genera are described: Comispira gen. nov. (Cochlespiridae), type species Leucosyrinx mai Li et Li, 2008; Pagodaturris gen. nov. (Clavatulidae), type species Pleurotoma molengraaffi Tesch, 1915.

Résumé [+] [-]This contribution provides novel information on the anatomy, radula and phylogeny of several species of Phaenomenella Fraussen & Hadorn, 2006, a genus of Buccinoidea Rafinesque, 1815 with unclear affinities. Molecular phylogenetic analysis based on sequences of mitochondrial COI and nuclear 28S rRNA genes of different representatives of Buccinoidea revealed close relationships of Phaenomenella with Siphonalia A. Adams, 1863 both taxa forming a clade with maximal support. The anatomy of two species of the latter genus was examined for the first time for comparative purposes. The subfamily Siphonaliinae Finlay, 1928 was erected for several Recent and fossil genera of Southern Hemisphere Buccinidae Rafinesque, 1815, and is still recognized by current taxonomists (Bouchet et al. 2017). Species of all Recent genera of Siphonaliinae were included in our analysis and the monophyly of the subfamily Siphonaliinae in its original scope is rejected. Molecular and morphological data revealed two still unnamed species of Phaenomenella from the lower bathyal zone of the South China Sea. These species, Phaenomenella nicoi n. sp. and P. samadiae n. sp. are described in the present study.

Résumé [+] [-]A unique radular configuration for Conoidea, consisting of five teeth in a transverse row (acuspate platelike central and laterals, and duplex marginal teeth), was found in three species previously described in the genus Clavatula: C. delphinae, C. pseudomystica and C. christianae. Analysis of the COI gene demonstrated that they belong to the family Clavatulidae. Paraclavatula n. gen. is described. No similar radulae have been found previously among Conoidea and their morphology suggests that the presence of well-defined lateral teeth is more broadly distributed within Conoidea than previously anticipated. Based on radular morphology alone, it would not be possible to attribute the genus to any presently recognized family of Conoidea.

Résumé [+] [-]According to a recent taxonomic revision by Kantor et al. (2001), the neogastropod genus Exilia Conrad, 1860, comprises ten mostly rare species that live at depths between 200 and 2000 m. Adult Exilia measure between 30 and 90 mm in shell length, and the genus is mostly represented in museum collections by empty shells. The abundance of this genus is low in the wild, but recent expeditions organized by the Muséum national d’Histoire naturelle have yielded several dozen specimens. These new collections include samples preserved for molecular studies. Here, we present the results of the first molecular systematic study of Exilia. Our aim was to investigate the species limits proposed by Kantor et al. (2001) on the basis of shell and anatomical characters. Analysis of DNA sequence data for the cytochrome c oxidase I gene suggests that Exilia hilgendorfi, previously considered to be a single, polymorphic and broadly distributed species, is a complex of at least six species (four of which we sequenced). Two of these species, Exilia cognata n. sp. and E. fedosovi n. sp., are described as new to science. Exilia gracilior, E. claydoni and E. prellei are resurrected from the synonymy of Exilia hilgendorfi; of these three, only the last was sequenced. Exilia vagrans is a welldefined taxon, but our molecular systematic data shows that it consists of two distinct species, which occur sympatrically off Taiwan and are strikingly similar in shell and radular morphology; due to the absence of DNA sequence data from the type locality of E. vagrans (Vanuatu), it is unclear to which of these two species the name would apply. Exilia karukera n. sp., which is conchologically very similar to E. vagrans, was discovered off Guadeloupe, represents the first record of the genus from the Atlantic. For E. elegans, which was previously known only from a single shell, we provide new data including new distributional records (South Africa and the Mozambique Channel), details of the radula and DNA sequence data.

Résumé [+] [-]Abstract The superfamily Buccinoidea is distributed across the oceans of the world from the Arctic Ocean to the Antarctic and from intertidal to abyssal depths. It encompasses 3351 recent species in 337 genera. The latest taxonomic account recognized eight full families. For the first time, the monophyly of the superfamily and the relationships among the families are tested with molecular data supplemented by anatomical and radula data. Five genetic markers were used: fragments of mitochondrial COI, 16S rRNA, 12S rRNA and nuclear Histone 3 (H3) and 28S rRNA genes (for 225 species of 117 genera). Our analysis recovered Buccinoidea monophyletic in Bayesian analyses. The relationships between the formerly recognized families and subfamilies are drastically revised and a new classification of the superfamily is here proposed, now including 20 taxa of family rank and 23 subfamilies. Five new families (Chauvetiidae, Dolicholatiridae, Eosiphonidae, Prodotiidae and Retimohniidae) and one subfamily of Nassariidae (Tomliniinae) are described. Austrosiphonidae and Tudiclidae are resurrected from synonymy and employed in a new taxonomical extension. All but 40 recent genera are reclassified. Our results demonstrate that anatomy is rather uniform within the superfamily. With exceptions, the rather uniform radular morphology alone does not allow the allocation of genera to a particular family without additional molecular data.

Résumé [+] [-]The anatomy of Ceratoxancus is characterized by a short or very short proboscis, the presence of an accessory sali vary gland, the ventral odontophoral retractor passing through the nerve ring, and the position of the buccal mass at the proboscis base in contracted condition. These characters are shared by other representatives of the subfamily and confirm the classification of Ceratoxancus in the Ptychatractinae, until now based on shell and radula characters. Ceratoxancus Kuroda, 1952, comprises six species of which four are described as new from the New Caledonia region in deep water (530-830 m). Ceratoxancus elongatus Sakurai, 1958, is removed from the synonymy of C. teramachii Kuroda, 1952, and both species are recorded from the south west Pacific. Species of Ceratoxancus with a long labral spine present numerous shell breakages, while toothless species have mu ch fewer scars, and it is hypothesized that the tooth and outer lip are used in prey capture with accompanying shell breakage.

Kantor Y.I., Bouchet P. & Oleinik A. 2001. A revision of the Recent species of Exilia, formerly Benthovoluta (Gastropoda: Turbinellidae). Ruthenica 11(2): 81-136
Résumé [+] [-]The range of shell characters (overall shape, sculpture, columellar plaits, protoconchs) exhibited by fossil and Recent species placed in Exilia Conrad, 1860, Mitraefusus Bellardi, 1873, Mesorhytis Meek, 1876, Surculina Dall, 1908, Phenacoptygma Dall, 1918, Palaeorhaphis Stewart, 1927, Zexilia Finlay, 1926, Graphidula Stephenson, 1941, Benthovoluta Kuroda et Habe, 1950, and Chathamidia Dell, 1956 and the anatomy of the Recent species precludes separation of more than one genus. Consequently all of these nominal genera are synonymised with Exilia, with a stratigraphical range from Late Cretaceous to Recent. Anatomically, Exilia is similar to other ptychatractine genera, but is characterized by a stomach with a long, narrow caecum, a penis with terminal fold surrounding the seminal papilla, and a radula with rachidian teeth with broad lateral flaps. Recent species of Exilia are restricted to deep water at middle to low latitudes in the Indian and Pacific oceans. Exilia hilgendorfi (Martens, 1897) is treated as a species highly variable within its broad IndoPacific distribution, with Benthovoluta gracilior Rehder, 1967, B. claydoni Harasewych, 1987, and B. prellei Bozzetti, 200 I considered local variants. Three new species are described: Exilia graphiduloides sp. nov. (New Caledonia, 520 m), E. vagrans sp. nov. (West and SW Pacific, 865-1280 m), and E. kiwi sp. nov. (New Zealand, 1386-1676 m).

Résumé [+] [-]The state of the art of turrid (=Turridae s. l.) systematics is that shells- when they include the protoconch - are reliable species-level identifiers, but inadequate proxies for allocation to genera or subfamilies. Generally, the radula is used for allocation to a (sub)family, but the hypothesis that the radula is a more adequate proxy than the shell for relationships has not yet been tested by molecular data. Species of Xenuroturris may have drastically different radulae, with either "'semi-enrolled" or "duplex" marginal teeth, although their shells are very similar or even almost indistinguishable. Molecular data confirm that specimens with different types of radulae constitute different species, but two species of a pair with respectively semi-enrolled and duplex teeth end up being not closely related. However, it is still unresolved whether species with semi-enrolled (=Iotyrris) and duplex teeth (=Xenuroturris) form two supported monophyletic clades. Iotyrris devoizei n.sp. and I. musivum n.sp. are described from Vanuatu, where they occur sympatrically with I. cingulifera and Xenuroturris legitima.

Résumé [+] [-]The hyperdiverse group of venomous Conoidea has eluded attempts to construct a robust and stable classification owing to the absence of a robust and stable phylogenetic framework. New molecular data have greatly enhanced our understanding of conoidean evolution, allowing the construction of a new family-level classification. This expanding framework has also allowed the discovery of several independent lineages that merit recognition at familial rank. One of these, based on seven specimens collected over more than 20 years from deep waters off New Caledonia, represents a unique, monotypic lineage closely related to Mitromorphidae, which we here name as the new family Bouchetispiridae. This new lineage bears a unique combination of teleoconch, protoconch and anatomical characters previously unknown within the Conoidea, including a translucent, fusiform shell with sculpture of strong axial ribs crossed by spiral cords, a multispiral protoconch of only 2.5 whorls with punctate sculpture, hypodermic marginal teeth and a multilayered venom bulb with two layers of muscle separated by connective tissue. This lineage may represent the sole survivor of a previously more diverse clade, or is simply one of many unique taxa that have arisen among the isolated sea mounts off New Caledonia.

Résumé [+] [-]The anatomy and evolution of the radular apparatus in predatory marine gastropods of the superfamily Conoidea is reconstructed on the basis of a molecular phylogeny, based on three mitochondrial genes (COI, 12S and 16S) for 102 species. A unique feeding mechanism involving use of individual marginal radular teeth at the proboscis tip for stabbing and poisoning of prey is here assumed to appear at the earliest stages of evolution of the group. The initial major evolutionary event in Conoidea was the divergence to two main branches. One is characterized by mostly hypodermic marginal teeth and absence of an odontophore, while the other possesses a radula with primarily duplex marginal teeth, a strong subradular membrane and retains a fully functional odontophore. The radular types that have previously been considered most ancestral, “prototypic” for the group (flat marginal teeth; multicuspid lateral teeth of Drilliidae; solid recurved teeth of Pseudomelatoma and Duplicaria), were found to be derived conditions. Solid recurved teeth appeared twice, independently, in Conoidea – in Pseudomelatomidae and Terebridae. The Terebridae, the sister group of Turridae, are characterized by very high radular variability, and the transformation of the marginal radular teeth within this single clade repeats the evolution of the radular apparatus across the entire Conoidea.

Résumé [+] [-]The new family Belomitridae is established for the deep-water buccinoid genus Belomitra P. Fischer, 1883, based on morphological (shell and radulae) and molecular evidence. The rachiglossate radula is uniquely characterized by a multicuspid rachidian and lateral teeth with very long narrow bases and two small cusps closer to tip. Molecular analysis of a reduced set of Buccinoidea did not resolve the group as a clade, but shows that Belomitridae forms a well supported clade within Buccinoidea. Species of Belomitra have adult sizes in the 7-53 mm range; they live in deep water, mostly in the 500-2,000 meters range, at low and mid latitudes. Eleven valid species described from the Indo-Pacific were originally named in the families Buccinidae, Columbellidae, Cancellariidae, Volutidae, and Turridae. Fourteen new species are described: Belomitra nesiotica n. sp. (Society Islands to Tonga and Fiji in 580-830 m), B. bouteti n. sp. (Society and Tuamotu Islands in 430-830 m), B. subula n. sp. (Solomon Islands to Vanuatu in 760-1110 m), B. caudata n. sp. (Sulu Sea in 2300 m), B. gymnobela n. sp. (South Pacific, eastern Indonesia and Philippines in 780-2040 m), B. hypsomitra n. sp. (Fiji in 392-407 m), B. brachymitra n. sp. (Fiji in 395-540 m), B. comitas n. sp. (Madagascar and Philippines in 1075-1110 m), B. minutula (Coral Sea in 490 m), B. granulata n. sp. (New Caledonia in 105-860 m), B. reticulata n. sp. (Tonga and Fiji to New Caledonia in 395-656 m), B. decapitata n. sp. (Indian Ocean and New Caledonia in 3680-4400 m), B. admete n. sp. (off Sri Lanka in 2540 m), and B. radula n. sp. (Madagascar in 367-488 m).

Journal of the Marine Biological Association of the United Kingdom 93(08): 2177-2195. DOI:10.1017/S0025315413000672
Résumé [+] [-]Buccinidae—like other canivorous and predatory molluscs—are generally considered to be occasional visitors or rare colonizers in deep-sea biogenic habitats. However, casual observations during tropical deep-sea cruises suggest that associations between buccinids and sunken wood, in particular, are not fortuitous. Enigmatocolus monnieri has been found to co-occur in Madagascar with bathymodiolines, vesicomyids and solemyids, indicating the presence of seeps, and species of Thermosipho gen. Nov. Have been sampled by submersibles and remotely operated vehicles, exclusively from hydrothermal vents. A molecular phylogeny (based on CO1, 12S and 28S genes) reveals that buccinid genera potentially associated with sunken wood (Eosipho, Gaillea gen. Nov., Calagrassor gen. Nov., and Manaria) are closely related to taxa from vents (Thermosipho gen. Nov.) and seeps (Enigmaticolus). The anatomy of several dissected species did not reveal any special trait that could be interpreted as a special adaptation to biogenic substrates. Buccinids from sunken wood are most diverse in the Indo-Pacific centre of marine biodiversity, the ‘Coral Triangle’, at depths between 100 and 1000 m, with numerous species still undescribed.

Résumé [+] [-]Most neogastropod families have a continuous record from the Cretaceous or Paleogene to the Recent. However, the fossil record also contains a number of obscure nominal families with unusual shell characters that are not adequately placed in the current classification. Some of these are traditionally regarded as valid, and some have been “lost” in synonymy. One such “lost” family is the Pyramimitridae, established by Cossmann in 1901 for the Eocene genus Pyramimitra, and currently included in the synonymy of Buccinidae. Examination of several species of inconspicuous, small turriform gastropods has revealed a radula type so far unknown in Neogastropoda, and their shell characters identify them as members of the "extinct" family Pyramimitridae. Neither the radular morphology nor the anatomy reveal the relationships of this enigmatic, “living fossil” family. Molecular data (12S, 16S, 28S, COI) confirm the recognition of Pyramimitridae as a distinct family, but no sister group was identified in the analysis. The family Pyramimitridae Cossmann, 1901, is thus restored as a valid family of Neogastropoda that includes the genera Pyramimitra Conrad, 1865, Endiatoma Cossmann, 1896, Vaughanites Woodring, 1928, Hortia Lozouet, 1999, and Teremitra new genus. Pyramimitrids occur in the Recent fauna at bathyal depths of the Indo- Pacific from Taiwan to Madagascar and New Zealand, with three genera and nine species (all but one new).

Résumé [+] [-]Five new species of Olivoidea are described based on molecular and morphological evidence: four shallow subtidal Ancilla from Madagascar and Papua New Guinea, and one deep water (500-600 m) Calyptoliva from the Tuamotus. The sympatric – but not syntopic - Ancilla morrisoni and A. kaviengensis, from New Ireland province, are morphologically cryptic, differing mostly in shell colour, but are molecularly distinct. The sympatric – and possibly syntopic – Ancilla atimovatae and A. lhaumeti, belong to a species flock from southernmost Madagascar; A. atimovatae is conchologically nearly indistinguishable from A. ventricosa, but differs markedly in radular morphology. Calyptoliva was previously known only from the Coral Sea; C. bbugae is the first representative of the genus to yield molecular data. The new Ancilla are described based on sequenced holotypes; the type material of the new Calyptoliva includes a sequenced paratype.

Résumé [+] [-]The genus Pseudolatirus Bellardi, 1884, with the Miocene type species Fusus bilineatus Hörnes, 1853, has been used for 13 Miocene to Early Pleistocene fossil species and eight Recent species and has traditionally been placed in the fasciolariid subfamily Peristerniinae Tryon, 1880. Although the fossil species are apparently peristerniines, the Recent species were in their majority suspected to be most closely related to Granulifusus Kuroda & Habe, 1954 in the subfamily Fusininae Wrigley, 1927. Their close affinity was confirmed by the molecular phylogenetic analysis of Couto et al. (2016). In the molecular phylogenetic section we present a more detailed analysis of the relationships of 10 Recent Pseudolatirus-like species, erect two new fusinine genera, Okutanius gen. nov. (type species Fusolatirus kuroseanus Okutani, 1975) and Vermeijius gen. nov. (type species Pseudolatirus pallidus Kuroda & Habe, 1961). Five species are described as new for science, three of them are based on sequenced specimens (Granulifusus annae sp. nov., G. norfolkensis sp. nov., Okutanius ellenae gen. et sp. nov.) and two (G. tatianae sp. nov., G. guidoi sp. nov.) are attributed to Granulifusus on the basis of conchological similarities to sequenced species. New data on radular morphology is presented for examined species.

Deep Sea Research Part I: Oceanographic Research Papers 160: 103256. DOI:10.1016/j.dsr.2020.103256
Résumé [+] [-]The abyssal and hadal Buccinoidea from the north-western Pacific formerly attributed to the genera Tacita and Calliloncha were analyzed for the first time using both multilocus molecular and morphological data. The results allow re-evaluation of the inter- and intrageneric variability of morphological characters and demonstrate that Tacita, Calliloncha and Paracalliloncha are synonyms of Bayerius, a genus widely distributed in the Pacific Ocean. In our reconstructed phylogeny the genus forms a maximally supported clade with Pararetifusus tenuis and Turrisipho dalli. At present, Bayerius includes 10 species, two of which are described herein as new to science, B. inflatus sp. nov. and B. nekrasovorum sp. nov. with one additional undescribed species represented in our material by a single specimen. The genus is reviewed, with the addition of new data on anatomy and distribution, based on newly obtained material. B. peruvianus is synonymized with B. zenkewitchi. Calliloncha nankaiensis together with Costaria crosnieri are attributed to a new genus, Warenius gen. nov., which clusters with several genera of Buccinoidea from biogenic substrata.

Résumé [+] [-]In the ancillariid genus Amalda, the shell is character rich and 96 described species are currently treated as valid. Based on shell morphology, several subspecies have been recognized within Amalda hilgendorfi, with a combined range extending at depths of 150–750 m from Japan to the South-West Pacific. A molecular analysis of 78 specimens from throughout this range shows both a weak geographical structuring and evidence of gene flow at the regional scale. We conclude that recognition of subspecies (richeri Kilburn & Bouchet, 1988, herlaari van Pel, 1989, and vezzaroi Cossignani, 2015) within A. hilgendorfi is not justified. By contrast, hilgendorfi-like specimens from the Mozambique Channel and New Caledonia are molecularly segregated, and so are here described as new, as Amalda miriky sp. nov. and A. cacao sp. nov., respectively. The New Caledonia Amalda montrouzieri complex is shown to include at least three molecularly separable species, including A. allaryi and A. alabaster sp. nov. Molecular data also confirm the validity of the New Caledonia endemics Amalda aureomarginata, A. fuscolingua, A. bellonarum, and A. coriolis. The existence of narrow range endemics suggests that the species limits of Amalda with broad distributions, extending, e.g., from Japan to Taiwan (A. hinomotoensis) or even Indonesia, the Strait of Malacca, Vietnam and the China Sea (A. mamillata) should be taken with caution.

Résumé [+] [-]The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two of which, Comitas and Leucosyrinx, belong to a different family, the Pseudomelatomidae. A molecular phylogenetic analysis of a large amount of material of Conoidea has revealed the existence of much additional undescribed diversity within Sibogasyrinx from the central Indo-Pacific and temperate Northern Pacific. Based on partial sequences of the mitochondrial cox1 gene and morphological characters of 54 specimens, 10 species hypotheses are proposed, of which six are described as new species: S. subula sp. nov., S. lolae sp. nov., S. maximei sp. nov., S. clausura sp. nov., S. pagodiformis sp. nov. and S. elbakyanae Kantor, Puillandre & Bouchet sp. nov. One of the previously described species was absent in our material. Most of the new species are very similar and are compared to Leucosyrinx spp. Species of Sibogasyrinx are unique among Conoidea on account of the high intrageneric variability in radular morphology. Three distinct radula types are found within Sibogasyrinx, two of which are confined to highly supported subclades.

Résumé [+] [-]The taxonomy of the genus Turris Batsch, 1789, type genus of the family Turridae, widespread in shallow-water habitats of tropic Indo-Pacific, is revised. A total of 31 species of Turris, are here recognized as valid. New species described: Turris chaldaea, Turris clausifossata, Turris guidopoppei, Turris intercancellata, Turris kantori, T. kathiewayae. Homonym renamed: Turris bipartita nom. nov. for Pleurotoma variegata Kiener, 1839 (non Philippi, 1836). New synonymies: Turris ankaramanyensis Bozzetti, 2006 = Turris tanyspira Kilburn, 1975; Turris imperfecti, T. nobilis, T. pulchra and T. tornatum Roding, 1798, and Turris assyria Olivera, Seronay & Fedosov, 2010 = T. babylonia; Turris dollyae Olivera, 2000 = Pleurotoma crispa Lamarck, 1816; Turris totiphyllis Olivera, 2000 = Turris hidalgoi Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000; Turris kilburni Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000 = Turris pagasa Olivera, 2000; Turris (Annulaturris) munizi Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000 = Gemmula lululimi Olivera, 2000. Revised status: Turris intricata Powell, 1964, Pleurotoma variegata Kiener, 1839 (non Philippi, 1836) and Pleurotoma yeddoensis Jousseaume, 1883, are regarded as full species (not subspecies of Turris crispa). Neotype designated: For Pleurotoma garnonsii Reeve, 1843, to distinguish it from Turris garnonsii of recent authors, type locality emended to Zanzibar. New combination: Turris orthopleura Kilburn, 1983, is transferred to genus Makiyamaia, family Clavatulidae.

Résumé [+] [-]Species of the genus Clavus of the conoidean family Drilliidae that occur in the littoral and shallow waters of New Caledonia are here revised. This study is based primarily on recent expedition material from the Institut de Recherche pour le Développement (New Caledonia) and Muséum National d’Histoire Naturelle (France). A total of 22 species is recorded, of which eight are described as new. New species: Clavus boucheti, Clavus delphineae, Clavus virginieae, Clavus picoides, Clavus squamiferus, Clavus devexistriatus, Clavus hylikos, Clavus maestratii; New synonyms: Tylotiella Habe, 1958 = Clavus; Clavus leforestieri Hervier, 1896 = Pleurotoma obliquicostata Reeve, 1845; Pleurotoma mariei Crosse, 1869 = Pleurotoma lamberti Montrouzier, 1860; Clavus mighelsi Kay, 1979, new name for Pleurotoma acuminata Mighels, 1845, non J. Sowerby, 1816, was misidentified by Kay 1979; the lectotype of P. acuminata Mighels, 1845, is mangeliine. Clavus mighelsi sensu Kay 1979, is a synonym of Pleurotoma humilis E. A. Smith, 1879. It is suggested that Pleurotoma pulchella Reeve, 1845, sometimes treated as an Indo-Pacific species, may be a senior synonym of Fenimorea halidorema Schwengel, 1940, from the tropical western Atlantic. Nomen dubium: Pleurotoma mediocris Deshayes, 1863.

Kirkendale L. 2021. A new photosymbiotic marine bivalve with window shell microstructure (Fraginae: Bivalvia). Phuket Marine Biological Center Research Bulletin 78: 125138. DOI:10.14456/PMBCRB.2021.9
Résumé [+] [-]Species of Fragum were collected from shallow waters in the Funafuti Atoll in Tuvalu in 2004, with one species being new. We describe Fragum funafutiense n. sp., which in addition to its occurrence at Funafuti, has now been found in five additional countries in the Indo-West Pacific. It can be differentiated from closely similar species only by consideration of a suite of characters that include shell shape, nature of the umbonal keel, rib number, rib sculpture, constitution of the hinge and nature of the shell window formation. Previously published molecular sequence data, including COI and 16S mtDNA, support this species as distinct from other tested fragines as well. Like all species in the genera Fragum, Corculum, and Lunulicardia, this new species is also photosymbiotic. In contrast to many other cardiids, however, Fragum funafutiense n. sp. exhibits deep penetration of fibrous prismatic microstructure on the posterior shell surface, consistent with window shell microstructure. Window shell microstructure is an adaptation that enhances light penetration through the shell to photosymbionts housed in soft tissue such as mantle, foot, and siphonal tentacles. A lectotype of its congener F. mundum (Reeve, 1845) is herein designated.

Knutson V.L. & Gosliner T.M. 2022. The first phylogenetic and species delimitation study of the nudibranch genus Gymnodoris reveals high species diversity (Gastropoda: Nudibranchia). Molecular Phylogenetics and Evolution 171: 107470. DOI:10.1016/j.ympev.2022.107470
Résumé [+] [-]Nudibranchs are charismatic marine gastropods that lack a shell in the adult stage. While most nudibranchs feed on sessile animals such as sponges, bryozoans, and cnidarians, the nudibranch genus Gymnodoris Stimpson, 1855 evolved a more active and predatory lifestyle, including sea slug predation, cannibalism, and oddly enough, fish-fin parasitism. At the beginning of our work, no phylogenetic hypothesis existed for the genus, nor a clear picture of how Gymnodoris is related to other nudibranchs. Here we set out to reconstruct Gymnodoris phylogeny, investigate species diversity, and clarify the status of the genus name Analogium, which had been proposed for members of the genus with a linear gill filament arrangement. We present the first phylogenetic hypothesis for Gymnodoris, reconstructed by maximum likelihood and Bayesian inference using two mitochondrial and two nuclear loci, with gill filament arrangement plotted on the phylogeny. The backbone of the phylogeny remains unresolved with theseloci, however, we found that Gymnodoris comprises three main well-supported clades, which we refer to as the “subornata”, “citrina” and “varied” clade, the latter two clades being comprised of several well-supported subclades. The sister group to Gymnodoris is a clade including the genera Vayssierea and Lecithophorus. Based on ABGD and PTP species delimitation methods, we conservatively estimate 65–70 species comprise our dataset. We further estimate that approximately 81% of the species we sampled are undescribed, and note that a linear gill filament arrangement has evolved multiple times within the genus. Gymnodoris is only monophyletic when the species with a linear gill arrangement are included. Therefore, at this time, we agree with the synonymy of Analogium striata with Gymnodoris striata by Rudman and Darvell (1990) and that the genus name Analogium is warranted as a junior synonym of Gymnodoris. Given the extensive undescribed diversity, and lack of resolution at some of the nodes in the phylogeny, patterns of diversification in diet are impossible to discern at this time and will require a large effort to both describe Gymnodoris species diversity and the diets of these candidate species.

Résumé [+] [-]Thirty-two species of Spondylus (Spondylidae) including eight previously undescribed, are recorded from material collected off New Caledonia and adjacent waters. Most of the species live in shallow water in coral reef and lagoonal environments, but at least four species have their main distribution at depths around 200 m, with one species occurring at 700 m. Spondylus exiguus sp. novo is the smallest known species in the family, with a maximum size of 6.4 mm. Spondylus flabellum Reeve, 1856 is placed into the synonymy of S. anacanthus Mawe, 1823. Confusion surrounding usage of the names Spondylus anacanthus and S. sanguineus Dunker, 1852 is finally resolved. The name Spondylus anacanthus, which has previously been applied to S. occidens Sowerby, 1903, is shown to be a prior and validly proposed name for S. sanguineus. Despite being well figured by MAWE, the absence of any documented type material for Spondylus anacanthus necessitates the establishment of a neotype for this species. Lectotypes are designated for Spondylus albibarbatus, S. butleri, S. castus, S. flabellum, S. ocellatus, S. pacificus, S. plurispinosus, and S. rubicundus, all of Reeve, 1856. By First Reviser action, the name Spondylus nicobaricus Schreibers, 1793 is given precedence over S. pseudochama Schreibers, 1793.

Résumé [+] [-]The Indo-West Pacific venerid genus Lioconcha is reviewed, with special emphasis on species occurring in the Australian and New Caledonian regions. Nineteen species, including four new species, are recognised: Lioconcha castrensis (Linnaeus, 1758), L. macaulayi n. sp., L. hieroglyphica (Conrad, 1837), L. tigrina (Lamarck, 1818), L. fastigiata (Sowerby, 1851), L. annettae Lamprell & Whitehead, 1990, L. pseudofastigiata n. sp., L. ornata (Dillwyn, 1817), L. berthaulti n. sp., L. sowerbyi (Deshayes, 1853), L. polita (Röding, 1798), L. schioettei n. sp., L. trimaculata (Lamarck, 1818), L. philippinarum (Hanley, 1844), L. dautzenbergi (Prashad, 1932), L. melharteae Lamprell & Stanisic, 1996, L. caledonensis Harte & Lamprell, 1999, L. richerdeforgesi Lamprell & Stanisic, 1996 and L. gordoni (E. A. Smith, 1885). Colour variation within species ranges from very high (L. ornata, L. castrensis) to very low (L. melharteae, L. caledonensis, L. philippinarum). All species are figured, diagnosed and discussed and a key is presented. Types of the following taxa are also figured: neotype of Venus ornata Dillwyn, 1817; holotypes of Lioconcha berthaulti n. sp.; L. macaulayi n. sp.; L. pseudofastigiata n. sp.; L. schioettei n. sp.; L. annettae Lamprell & Whitehead, 1990; Cytherea tigrina Lamarck, 1818; Hysteroconcha (?Lamelliconcha) dautzenbergi Prashad, 1932 and Cytherea sulcatina Lamarck, 1818; lectotypes of Cytherea hebraea Sowerby, 1851 and Circe sowerbyi Deshayes, 1853. Lectotypes of Cytherea hieroglyphica Conrad and C. fastigiata Sowerby are based on original figures, in the absence of other undoubted type material. Subdivision of Lioconcha into two subgenera (Lioconcha sensu stricto and Sulcilioconcha), based solely on the presence or absence of concentric ridge sculpture, appears unwarranted.

Leal J.H. 2008. A remarkable new genus of carnivorous, sessile bivalves (Mollusca: Anomalodesmata: Poromyidae) with descriptions of two new species. Zootaxa 1764: 1-18
Résumé [+] [-]Dilemma, a new genus of sessile septibranch bivalves is described. The new taxon encompasses at least three species, of which two are new: D. frumarkernorum new species, from off the Florida Keys, D. spectralis new species, from off Vanuatu, and “Corculum” inexpectatum Crozier, 1966, from off the Three Kings Islands, New Zealand, known only from its shell. The absence of ctenidia and presence of a septum, size and arrangement of siphons and siphonal tentacles, extensive fusion of the mantle margins allocate the new genus within the septibranch bivalves. A siphonal area with 15 tentacles, a large and eversible incurrent siphon, ostial apertures in the septum, and a hermaphroditic reproductive system suggest inclusion in the Poromyidae. The presence of three paired groups of septal ostia in the new genus is a feature shared with poromyids in the genus Cetoconcha. Unusual symmetry and form constitute the most striking features of the new genus. There is a strong anteroposterior compression and lateral expansion associated with ca. 30º rotation of the largest dimension (height) in relation to the anteroposterior axis. The shell hinge includes a single tooth and socket on each valve, and an external, but deeply sunken ligament. The two new species, mutually distinguishable by shell and anatomical characters, are known from live-collected specimens found adhering to rocks by means of robust byssus, which indicates attachment for life. The presence of ostracod remains in the digestive tract of one specimen of one of the new species and of a cirolanid isopod in the stomach of the holotype of the second new species are evidence of predation. Although predation by infaunal and free-living bivalves is known to occur throughout the Anomalodesmata, in particular within the septibranchs, discovery of the new genus reveals an unusual instance of predation by sessile, permanently attached mollusks.

Résumé [+] [-]The use of phylogeny with uneven or limited taxon sampling may bias our interpretation of organismal evolution, for instance, the origin(s) of the deep-sea animals. The Mollusca is the second most speciose phylum, in which the Gastropoda forms the largest group. However, the currently proposed hypotheses of gastropod phylogeny are mainly based on part of their taxonomic diversity, notably on the large-sized and shallow-water species. In this study, we aimed at correcting this bias by reconstructing the phylogeny with new mitogenomes of deep-sea gastropods including Anatoma sp., Bathysciadiidae sp., Bayerotrochus teramachii, Calliotropis micraulax, Coccocrater sp., Cocculina subcompressa, Lepetodrilus guaymasensis, Peltospira smaragdina, Perotrochus caledonicus, Pseudococculinidae sp., and Shinkailepas briandi. This dataset provided the first reports of the mitogenomes for the Cocculiniformia, three vetigastropod superfamilies: Pleurotomarioidea, Lepetelloidea, and Scissurelloidea, and the neritimorph family Phenacolepadidae. The addition of deep-sea representatives also allowed us to evaluate the evolution of habitat use in gastropods. Our results showed a strongly supported sister-group relationship between the deep-sea lineages Cocculiniformia and Neomphalina. Within the Vetigastropoda, the Pleurotomarioidea was revealed as the sister-group of the remaining vetigastropods. Although this clade was presently restricted to the deep sea, fossil records showed that it has only recently invaded this habitat, thus suggesting that shallow waters was the ancestral habitat for the Vetigastropoda. The deep-sea Lepetelloidea and Lepetodriloidea formed a well-supported clade, with the Scissurelloidea sister to it, suggesting an early transition from shallow water to deep sea in this lineage. In addition, the switch between different chemosynthetic habitats was also observed in deep-sea gastropod lineages, notably in Neomphalina and Lepetelloidea. In both cases, the biogenic substrates appeared as the putative ancestral habitat, confirming the previously proposed hypothesis of a wooden-step to deep-sea vents scenario of evolution of habitat use for these taxa.

Résumé [+] [-]The family Pinnidae Leach, 1819, includes approximately 50 species of large subtidal and coastal marine bivalves. These commercially important species occur in tropical and temperate waters around the world and are most frequently found in seagrass meadows. The taxonomy of the family has been revised a number of times since the early 20th Century, the most recent revision recognizing 55 species distributed in three genera: Pinna, Atrina and Streptopinna, the latter being monotypic. However, to date no phylogenetic analysis of the family has been conducted using morphological or molecular data. The present study analyzed 306 pinnid specimens from around the world, comprising the three described genera and ca. 25 morphospecies. We sequenced the mitochondrial genes 16S rRNA and cytochrome c oxidase subunit I, and the nuclear ribosomal genes 18S rRNA and 28S rRNA. Phylogenetic analysis of the data revealed monophyly of the genus Atrina but also that the genus Streptopinna is nested within Pinna. Based on the strong support for this relationship we propose a new status for Streptopinna Martens, 1880 and treat it as a subgenus (status nov.) of Pinna Linnaeus, 1758. The phylogeny and the species delimitation analyses suggest the presence of cryptic species in many morphospecies displaying a wide Indo-Pacific distribution, including Pinna muricata, Atrina assimilis, A. exusta and P. (Streptopinna) saccata but also in the Atlantic species A. rigida. Altogether our results highlight the challenges associated with morphological identifications in Pinnidae due to the presence of both phenotypic plasticity and morphological stasis and reveal that many pinnid species are not as widely distributed as previously thought.

Résumé [+] [-]Bathymodiolin mussels occur at hydrothermal vents and cold seeps, where they thrive thanks to symbiotic associations with chemotrophic bacteria. Closely related genera Idas and Adipicola are associated with organic falls, ecosystems that have been suggested as potential evolutionary 'stepping stones' in the colonization of deeper and more sulphide-rich environments. Such a scenario should result from specializations to given environments from species with larger ecological niches. This study provides molecular-based evidence for the existence of two mussel species found both on sunken wood and bones. Each species specifically harbours one bacterial phylotype corresponding to thioautotrophic bacteria related to other bathymodiolin symbionts. Phylogenetic patterns between hosts and symbionts are partially congruent. However, active endocytosis and occurrences of minor symbiont lineages within species which are not their usual host suggest an environmental or horizontal rather than strictly vertical transmission of symbionts. Although the bacteria are close relatives, their localization is intracellular in one mussel species and extracellular in the other, suggesting that habitat choice is independent of the symbiont localization. The variation of bacterial densities in host tissues is related to the substrate on which specimens were sampled and could explain the abilities of host species to adapt to various substrates.

Résumé [+] [-]Bathymodiolinae mussels have been used as a biological model to better understand the evolutionary origin of faunas associated with deep-sea hydrothermal vents and cold seeps. Most studies to date, however, have sampled with a strong bias towards vent and seep species, mainly because of a lack of knowledge of closely related species from organic falls. Here we reassess the species diversity of deep-sea mussels using two genes and a large taxon sample from the South-Western Pacific. This new taxonomic framework serves as a basis for a phylogenetic investigation of their evolutionary history. We first highlight an unexpected allopatric pattern and suggest that mussels usually reported from organic falls are in fact poorly specialized with regard to their environment. This challenges the adaptive scenarios proposed to explain the diversification of the group. Second, we confirm that deep-sea mussels arose from organic falls and then colonized hydrothermal vents and cold seeps in multiple events. Overall, this study constitutes a new basis for further phylogenetic investigations and a global systematic revision of deep-sea mussels. (C) 2010 Elsevier Inc. All rights reserved.

Résumé [+] [-]Adaptive radiations present fascinating opportunities for studying the evolutionary process. Most cases come from isolated lakes or islands, where unoccupied ecological space is filled through novel adaptations. Here, we describe an unusual example of an adaptive radiation: symbiotic mussels that colonized island-like chemosynthetic environments such as hydrothermal vents, cold seeps and sunken organic substrates on the vast deep-sea floor. Our time-calibrated molecular phylogeny suggests that the group originated and acquired sulfur-oxidizing symbionts in the Late Cretaceous, possibly while inhabiting organic substrates and long before its major radiation in the Middle Eocene to Early Oligocene. The first appearance of intracellular and methanotrophic symbionts was detected only after this major radiation. Thus, contrary to expectations, the major radiation may have not been triggered by the evolution of novel types of symbioses. We hypothesize that environmental factors, such as increased habitat availability and/or increased dispersal capabilities, sparked the radiation. Intracellular and methanotrophic symbionts were acquired in several independent lineages and marked the onset of a secondwave of diversification at vents and seeps. Changes in habitat type resulted in adaptive trends in shell lengths (related to the availability of space and energy, and physiological trade-offs) and in the successive colonization of greater water depths.

Mémoires du Muséum national d'Histoire naturelle 150:205-222, ISBN:2-85653-180-6
Résumé [+] [-]The first Recent species of Eumitra are described from deep-water in the New Caledonian region : E. caledonica sp. nov. (Southern New Caledonia), E. apheles sp. nov. (Northern New Caledonia), E. imbucata sp. nov. (Coral Sea, Lansdowne-Fairway) and E. richeri sp. nov. (Coral Sea, Mellish Reef). A SEM photograph of the radula is included. Fossil Eumitra are restricted to lower Miocene of New Zealand and Miocene/Pliocene of Australia. Dispersal is advocated to explain Eumitra distribution. For the first time fossil species from Upper Oligocene of Aquitaine Basin (Southwestern France) are referred to Charitodoron. Anatypical member of the Mitridae : C. tau:ini sp. Nov. And C. cancellatus (Saubade, 1969). The three Recent Charitodoron are confined to the bathyal zone of South Africa, fossil Oligocene species have been collected from a bathyal palaeocommunity. In spite of columellar similarities, peculiar development of columellar folds (Eumitra) or edentulous columella (Charitodoron), these two genera are probably not closely related. In a paleobiogeographic discussion two key events are cited to explain the beginning of many marine disjunctions : Upper Eocene/Lower Oligocene crisis and closing of Tethys in Upper Oligocene/Lower Miocene.

Résumé [+] [-]Neritopsis richeri n. sp., the fourth Recent species of a group of "living fossil" molluscs, is described from the Austral Islands (French Polynesia). Most of the material was collected during the BENTHAUS cruise. This species differs from its congeners in teleoconch sculpture, which has I to 4 secondary cords in the interspaces between the primary cords. The spiral ribs are also weakly headed. In addition, and in contrast to the common species N. radula (Linnaeus, 1758), N. richeri it. sp. has a multispiral protoconch that implies a planktotrophic larval development. Its relationship to N. aqabaensis Bandel, 2007 described from an immature specimen is difficult to assess, the Sculpture of adults suspected to be N. aqabaensis being identical to that of N. radula, Neritopsis richeri n. sp. appears to be restricted to French Polynesia but possibly has been confused with N. radula in previous publications.

Résumé [+] [-]This revision of the scissurellid genus Satondella Bandel, 1998 is mainly based on shell characters due to the availability of only a few live collected specimens. There are seven Recent species (two described as new) and one Eocene fossil. Satondella minuta Bandel, 1998, the type species from Indonesia, is redescribed and its range extended to New Caledonia, Solomon and Fiji Islands. Satondella tabulata (Watson, 1886) is only known from type material off Culebra Island (Puerto Rico); lectotype and paralectotypes are here designated, and similar material from the Indo-Pacific is discussed. Satondella brasiliensis (Mattar, 1987) is another W. Atlantic species, ranging from Bermuda to Brazil. Satondella senni (Geiger, 2003) is only known from the E. Pacific (Easter Island) and Satondella danieli Segers, Swinnen & Abreu, 2009 from the NE. Atlantic Ocean (Desertas and Madeira Islands). The two new species are distributed through the E. Indian and W. Pacific oceans (S. cachoi n. sp.) and W. Pacific (S. dantarti n. sp.). The Tongan Eocene fossil S. kondoi (Ladd, 1970) is redescribed and illustrated with SEM images. Satondella brasiliensis and S. cachoi have a typical scissurellid radula, except for uniquely having one cusp on the inner edge of the third lateral. The monophyly of the genus is discussed, since species currently included in Satondella show two clearly different shell patterns but all share the unique chimney-like foramen.

Résumé [+] [-]Bullidae are a worldwide family of marine shelled cephalaspidean gastropods with a mainly tropical distribution, but also with some representatives in temperate waters. The taxonomy of the group has in the past been based only on shell characters, and the few anatomical accounts available have not addressed more than one to three species, so there has been no agreement about the number of valid species. Seventy-two specific names and 16 varietal names have been proposed worldwide. The systematics of the family Bullidae are revised, based not only on shells but also on anatomy of all extant species and on DNA sequence data. Twelve species are recognized worldwide, including one new species here described, and all are assigned to the genus Bulla. Two species occur in the eastern Atlantic, B. striata and B. mabillei; two in the western Atlantic, B. occidentalis and B. solida; two in the eastern Pacific, B. gouldiana and B. punctulata; and six in the Indo-West Pacific, B. ampulla, B. arabica sp. Nov., B. orientalis, B. peasiana, B. quoyii and B. vernicosa. Full synonymies and taxonomic histories are provided for each species. In order to promote taxonomic stability, neotypes are designated for B. striata, B. solida, B. nebulosa (valid name B. gouldiana) and B. vernicosa, and lectotypes for B. occidentalis, B. mabillei, B. punctulata, B. ampulla and B. quoyii. The type locality of B. ampulla is restricted to Mauritius. Bullidae show a general morphological stasis, with anatomy being very similar between species. However, there are high levels of intraspecific variability in the shell, radula and male genital system. In some cases species could only be separated based on molecular data . After defining the characters and geographical range of each species it became clear that sympatric species (a maximum of three) show distinctive shells and reproductive structures, which makes identification straightforward. This study employs an integrative approach, combining information on shells, anatomy, DNA and geographical distribution, in order to resolve the systematics of a difficult taxonomic group.

Résumé [+] [-]The discovery of 11 Nautilus macromphalus shells in marine environments near New Caledonia constitutes the first opportunity for taphonomic analysis of empty shells of unburied, externally shelled cephalopods on the seafloor. Radiometric dating indicates specimen ages range from 14 to 42 years. These modern specimens provide a unique opportunity to examine the early, preburial taphonomy of this group of animals including shell condition, radiometric-age dating, epizoan encrustation, color degradation, and sediment infilling. The following conclusions are made: (1) given the limited sample available for study and assuming equal conditions where shells rested on the seafloor, the length of time the shell is unburied will not control the degree of epizoan encrustation or the external shell appearance; (2) shell boring is a major destructive process that probably impacts the potential of the shells to become fossilized; and (3) shells in the photic zone are impacted differently than those dredged from a deep water environment below the photic zone. A major part of this difference is probably the result of both boring and encrusting organisms, especially algae. By comparison, fossil cephalopods as a general group can be expected to vary considerably from the modern specimens because of evolutionary patterns of associated organisms, geographic distribution, and different environments with different paleoecological parameters through time. Caution in overreliance on the taphonomy of these modern shells should be exercised because of the limited sample of Nautilus specimens recovered. The need for additional taphonomic studies of modern externally shelled cephalopods with the recovery of more specimens from the marine environment is highly desirable.

Résumé [+] [-]New genera Thysanodonta, Carinastete and Herbertina are referred to a new subfamily of the Trochidae, Thysanodontinae, on the basis of extremely distinctive jaw and radula. At up to 1400 times longer than broad , the teeth are the most slender of any known gastropod, and they are unique among archaeogastropods in having harpoon-like tips with backwardly inclined barbs. While food and feeding mode are unknown , it is suggested that they feed suctorially, perhaps on cnidarians. New species described are Thysanodonta aucklandica , T. wairua, Carinastele kristelleae, C. jugosa , and C. coronata from New Zealand, T. boucheti from New Caledonia, and Herbertina eos and H. cognata from South Africa. The Tasmanian Basilissa nicetarium Hedley & May is tentatively referred to Carinastele.

Résumé [+] [-]Thirty species (27 new) of Calliostomatidae are recorded from the study region, all but two of which are new records. An additional new species is based on material from northern New Zealand. They are referred to Fautor Iredale, 1924, Benthastelena Iredale, 1936, Ampullotrochus Monterosato, 1890 (as subgenera of Calliostoma Swainson, 1840), Bathyfautor gen. nov., Dactylastele gen. nov., Laetifautor Iredale, 1929, Selastele gen. nov., Fautrix gen. nov., and Thysanodonta Marshall, 1988. A new tribe, Fautricini, is introduced for species with a radula that is evidently the most primitive (plesiomorphic) in the family, and Fautricini either represents the common basal stock or an early offshoot from it. Calliostomatidae is treated as a family within Trochoidea rather than a subfamily of Trochidae as has been traditional. Three calliostomatid genus group taxa are newly synonymised: Tristichotrochus Ikebe, 1942 ( = Benthastelena Iredale, 1936), Salsipotens Iredale, 1924 (= Astele Swainson, 1840), Spicator Cotton & Godfrey, 1935 ( = Laetifautor Iredale, 1929). Criteria used for taxonomic discrimination, evolutionary history, and some biogeographical observations are discussed. All calliostomatid genus group taxa and taxa removed (some newly) from the family are listed in appendices. A lectotype is designated for Zizyphinus scobinatus A. Adams, 1863.

Résumé [+] [-]Helicopeltinae, a new subfamily of the Addisoniidae. is proposed for a group of minute deep-sea gastropods found living and feeding on detrital cephalopod beaks from the Chesterfield Plateau and southern New Caledonia. The type species of Helicopelta gen. nov., H. rostricola sp. nov., uniquely combines an operculate, coiled shell similar to that in Choristella Bush, 1987 (Choristellidae), a horseshoe-shaped shell muscle characteristic of a limpet, a radular similar to that in Addisoniidae but with more numerous marginal teeth and non-homologous primary rasping teeth, a large left centered gill, and a copulatory organ that is situated on the left side instead of the right as in all other members of the Lepetelloidea. A second (unnamed) species Helicopelta is recorded from off southern New Caledonia. The opportunity is taken to describe a new limpet of the genus Tentaoculus Moskalev, 1976, fro New Zealand that lives and feeds within pent chondrichthyan egg cases, the first record of a pseudococculinid from this habitat. Radalue of Teuthirostria cancellata Moskalev, 1976, and of species of Addisonia, Choristella, and Bathysciadium are illustrated and discussed.

Résumé [+] [-]Living species of Meiocardia, Glossidae, are reviewed on the basis of specimens stored in various museums and institutions, including the MUSORSTOM collection of Museum national d'Histoire naturelle, Paris. Six species, one of them new, are reported from the Indo-West Pacific. The type species, M. moltkiana (Gmelin, 1791), has been variously interpreted by authors, so we redescribe it and give a new diagnosis of the genus. Other species of Meiocardia are: M. sanguineomaculata (Dunker, 1882) (Philippines to Seychelles); M. vulgaris (Reeve, 1845) (China to Philippines); M. globosa sp. nov. (eastern Indian Ocean to Taiwan and Philippines); M. samarangiae Bernard, Cai & Morton, 1993 (Japan); and M. hawaiana Dall, Bartsch & Rehder, 1938 (western Indian Ocean to Hawaii). Meiocardia lamarckii (Reeve, 1845) is synonymised with M. moltkiana. Meiocardia lamarckii of Japanese authors is not the same as M. lamarckii (Reeve), but is conspecific with M. hawaiana. Meiocardia samarangiae Bernard, Cai & Morton, 1993 is a replacement name for Isocardia tetragona Adams & Reeve, 1850 non Koch & Dunker, 1837. The genus Glossocardia, Trapezidae, is redescribed on the basis of the type-species, Glossocardia obesa (Reeve, 1843) (tropical West Pacific). It includes Glossocardia stoliczkana Prashad, 1932 (Philippines and New Caledonia) and the tropical western Atlantic G. agassizii (Dall, 1886), which was originally assigned to Meiocardia. There are no records of living or fossil species of Meiocardia from the western Atlantic or eastern Pacific.

Mclean J.H. & Quinn J.F.J. 1987. Cataegis, New Genus of Three New Species from the Continental Slope (Trochidae: Cataeginae New Subfamily). The Nautilus 101(3): 111-116
Résumé [+] [-]Cataegis new genus, type species C. toreuta new species, is proposed to include three new species from continental slope depths (200-2000 m): the type species and C. meroglypta from the Gulf of Mexico to Colombia, and C. celebesensis from Makassar Strait, Indonesia. Important shell characters are the prominent spiral cords, non-umbilicate base, and oblique aperture. The radula is unique among the Trochidae in lacking the rachidian, having the first pair of laterals fused and uncusped, and the first marginals enlarged. The gill is the advanced trochid type with well-developed afferent membrane. These characters do not correspond to an available subfamily; the new subfamily Cataeginae is therefore proposed.

Cretaceous and living Colloniidae of the redefined subfamily Petropomatinae, with two new genera and one new species, with notes on opercular evolution in turbinoideans, and the fossil record of Liotiidae (Vetigastropoda : Turbinoidea). Paläontologische Zeitschrift 81(3): 254-266
Résumé [+] [-]Opercular characters are of major importance to understanding the living and fossil groups in the vetigastropod superfamily Turbinoidea RAFINESQUE. Here we evaluate current knowledge of fossil turbinoid opercula in the light of a newly discovered Recent colloniid with an unfamiliar opercular morphology. The operculum of Liotipoina n.gen. has a multispiral and conical inner surface; the outer surface is rugose with a central pit. Similar opercula are known from the Late Cretaceous Sohlipoina n. gen. and the Early Cretaceous Petropoma GABB. These genera are assigned to the here redefined colloniid subfamily Petropomatinae Cox in KNIGHT et al., which was based originally on GABB'S misinterpretation of the inner and outer sides of the operculum of Petropoma peruana GABB. In contrast. opercula of most living members of Colloniinae s.s., have a flat inner side with a multispiral pattern that becomes paucispiral. In addition. opercula typical for living Turbinidae are here traced to the Late Cretaceous. The new genus Liotipoma has lamellar sculpture like that of Liotiidae H. & A. ADAMS, showing that such sculpture is not restricted to the Liotiidae. We also reject previous allocations of the Permian Dichostasiinae YOCHELSON and Jurassic Cross-ostornatinae Cox in KNIGHT et al. to Liotiidae, and find an undisputed earliest known Jurassic occurrence for the Liotiidae. The recent suggestion that the change from corneous to calcareous opercula among turbinids occurred concurrently with a change in pattern from multispiral to paucispiral is not supported by our data.

Résumé [+] [-]The genus Liotipoma McLean & Kiel, 2007, was proposed for a remarkable small-shelled gastropod genus from coral reefs of the Indo-Pacific that resemble the family Liotiidae Gray, 1850 in having fine axial lamellae and a thickened terminal lip, but differ in having the solid calcareous operculum of the family Colloniidae Cossmann, 1916. The genus was originally assigned to the otherwise Cretaceous subfamily Petropomatinae Cox, 1960 of the family Colloniidae, because the inner side of the operculum is multispiral, conical and projecting, as in the Mesozoic genera assigned to Petropomatinae. Here the genus Liotipoma is assigned to a new colloniid subfamily Liotipomatinae n. subfam., because its axial lamellae are unknown in the Cretaceous genera of Petropomatinae. Four genera are now recognised; all species are known from shell grit samples collected by diving or dredging at coral reefs from recent MNHN expeditions to New Caledonia, the Loyalty Islands, Espiritu Santo (Vanuatu) and Wallis Island, and also from LACM material from Fiji, Papua New Guinea, and the Marshall Islands. The most speciose genus is Liotipoma, with eight known species, seven of which are new and described here the largest known species is L. magna n. sp. From Santo, Vanuatu. Also described are: Depressipoma n. gen. With two new species from the Marshall Islands; Rhombipoma n. gen., with one new species from Rowley Shoals, northwestern Australia; and Paraliotipoma n. gen., with one new species from Sea Horse Shoal, South China Sea. Although live-collected specimens are still unknown, sexual dimorphism in Liotipoma was reported for the type species when the genus was described. Here it is reported from four of the eight known species of that genus, expressed in expansion of the umbilical cavity as a brood chamber in the female shell, as previously reported in the families Liotiidae and Colloniidae. In two species the worn female shell shows an irregular degradation of the umbilical cavity, which is considered the effect of bearing a large egg mass and brood. For reasons unknown, female shells of most species of Liotipoma are much less frequent than male shells. Formal validation of Areneidae n. fam. Is provided in an addendum to this paper.

Résumé [+] [-]The foregut anatomy of 20 species, belonging to eight genera, of the subfamily Cochlespirinae is described. A cladistic analysis based on sevral most important characters (morphology of proboscis, position of buccal sphincters, histology of venom gland, position of the venom gland opening, structure of muscular bulb, and morphology of radular teeth) revealed three more or less well defined groups within the subfamily. The main feature characterizing the subfamily as a whole and separating groups within it, appeared to be the structure of venom gland and its muscular bulb. The subgenus Sibogasyrinx of the genus Leucosyrinx was shown to deserve agenus status. Some genera appeared to be intermediate between Cochlespirinae and Crassispirinae in some anatomical characters, and their taxonomic position remains not completely clear.

Résumé [+] [-]The foregut anatomy of 22 species of the subfamily Turrinae, belonging to 12 genera, is described. A cladistic analysis made based on the characters of anatomy of the digestive system and morphology of radular teeth. The main result of the analysis was the separation of the subfamIly I11t.O .two rather large groups, one of which is in turn subdlVlded into two subgroups. Fusiturris similis, F. undatiruga, Cryptogemma corneus, "Turris" torta and Polystira jormosissima belong to the first group. In. The second group the main subgroup include all species of genus Gemmula and Gemmuloborsonia. Besides anatomical differences , species belonging to different groups have a differing geographical distribution. The new data obtained as a result of last works allow to define the anatomical characteristics of other turrids subfamilies.

Résumé [+] [-]The histological structure of poison gland and muscular bulb in the family Turridae has been examined. The data on anatomy of about 50 species studied form the basis of the work. A correlation was revealed between the structure of poison gland itself, position of its duct, and the inner structure of muscular bulb. Six main types and 3 subtypes were recognized in the structure of poison gland - muscular bulb complex. Taking into account the high variability of the anterior paft of digestive system in Turridae, the isolation of the complex of characters, which can unite groups of genera, is of certain interest for the taxonomy of the family.

Résumé [+] [-]The anatomy of Zemacies excelsa is characterized by an absence of typical conoidean foregut organs, viz. radula and poison gland. There are autapomorphic features, such as the large rhynchodeal pyriform gland of unknown function. The anatomical organization of the foregut is dissimilar to any other group of Turridae. Because of these distinctive anatomical features a new subfamily Zemaciinae is proposed included in the family Turridae for the reason of conchological similarity.

Résumé [+] [-]The primary cords of 68 species belonging to the Muricopsis/Murexsul lineages (Priabonian to Recent) are analysed. The study of their development allows distinguishing three derived sculptural patterns in Muricopsis and three in the Murexsul group. They appear late in the evolutionary history of the studied lineages, mainly in tropical waters. They are produced by heterochronies affecting precise cords by paedomorphosis, whereas others poorly evolved or may be hypermorphic. These results suggest that the phase of sculptural increase yielding the primitive pattern is followed by a selective phase, preserving or increasing the relief of the probable most functional cords.

Résumé [+] [-]The chiefly tropical, deep-water (>100 m) feather star family Charitometridae (Echinodermata: Crinoidea: Comatulida) currently consists of 34 species in eight genera and has not been revised since 1950. Recent molecular analyses and the discovery of both new specimens of known species and a new species prompted a morphological re-examination of those genera with abruptly expanded genital pinnules. As a result, Poecilometra is redescribed, and now includes four species, including two formerly placed in Strotometra, plus Poecilometra baumilleri n. sp Poecilometra scalaris is placed in synonymy under P. acoela. Strotometra is redescribed and S. hepburniana placed in synonymy under S. parvipinna. The diagnoses of both genera and their component species are revised.

Résumé [+] [-]In this paper, the relationships of Tritonoharpa Dall, 1908, within Neogastropoda are discussed. Tritonoharpa is indeed similar to Colubraria in the morphology of its head-foot, pallial complex, reproductive and excretory systems, in the presence of an extremely long and coiled proboscis, and a very large stomach. However, it differs from Colubraria in the rest of its foregut anatomy, revealing a cancellariid affinity, and a typical nematoglossan radula. The molecular data confirms Beu and Maxwell's placement of Tritonoharpa in the Cancellariidae close to Plesiotriton. It is also suggested that cancellariids may be the sister-group to the rest of neogastropods. Tritonoharpa has a rather large and well developed midgut gland, resembling the gland of Leiblein. As previously studied cancellarioideans have been shown to lack a well differentiated gland of Leiblein, the present study raises some interesting questions about the evolution of the foregut in Neogastropoda. In fact, if this glandular structure were confirmed as a true homologue of the gland of Leiblein, and the cancellarioideans proved to be the sister group to the remaining neogastropods, the possession of the gland should be considered a synapomorphy of the Neogastropoda.

Résumé [+] [-]Cancellariidae, or nutmeg shells, is a family of marine gastropods that feed on the body fluids and the egg cases of marine animals. The 300 or so living species are distributed worldwide, mostly on soft bottoms, from intertidal to depths of about 1000 m. Although they are a key group for the understanding of neogastropod evolution, they are still poorly known in terms of anatomy, ecology and systematics. This paper reports the first mitochondrial multi-gene phylogenetic hypothesis for the group. Data were collected for 50 morphospecies, representative of 22 genera belonging to the three currently recognized subfamilies. Sequences from three genes (12S, 16S and COI) were analyzed with Maximum Likelihood analysis and Bayesian Inference, both as single gene datasets and in two partitioned concatenated alignment. Largely consistent topologies were obtained and discussed with respect to the traditional subfamilial arrangements. The obtained phylogenetic trees were also used to produce Robinson-Foulds supertrees. Our results confirmed the monophyly of the subfamily Plesiotritoninae, while Admetinae and Cancellariinae, as currently conceived, were retrieved as polyphyletic. Based on our findings we propose changes to the systematic arrangement of these subfamilies. At a lower taxonomic rank, our results highlighted the rampant homoplasy of many characters traditionally used to segregate genera, and thus the need of a critical re-evaluation of the contents of many genera (e.g. Nipponaphera, Merica, Sydaphera, Bivetia), the monophyly of which was not recovered.

DOI:10.1093/sysbio/syz059
Résumé [+] [-]Abstract How species diversification occurs remains an unanswered question in predatory marine invertebrates, such as sea snails of the family Terebridae. However, the anatomical disparity found throughput the Terebridae provides a unique perspective for investigating diversification patterns in venomous predators. In this study, a new dated molecular phylogeny of the Terebridae is used as a framework for investigating diversification of the family through time, and for testing the putative role of intrinsic and extrinsic traits, such as shell size, larval ecology, bathymetric distribution, and anatomical features of the venom apparatus, as drivers of terebrid species diversification. Macroevolutionary analysis revealed that when diversification rates do not vary across Terebridae clades, the whole family has been increasing its global diversification rate since 25 Ma. We recovered evidence for a concurrent increase in diversification of depth ranges, while shell size appeared to have undergone a fast divergence early in terebrid evolutionary history. Our data also confirm that planktotrophy is the ancestral larval ecology in terebrids, and evolutionary modeling highlighted that shell size is linked to larval ecology of the Terebridae, with species with long-living pelagic larvae tending to be larger and have a broader size range than lecithotrophic species. Although we recovered patterns of size and depth trait diversification through time and across clades, the presence or absence of a venom gland (VG) did not appear to have impacted Terebridae diversification. Terebrids have lost their venom apparatus several times and we confirm that the loss of a VG happened in phylogenetically clustered terminal taxa and that reversal is extremely unlikely. Our findings suggest that environmental factors, and not venom, have had more influence on terebrid evolution.

Résumé [+] [-]Donacidae is a commercially important family of heterodont bivalves and one of the few bivalve lineages that has successfully colonised brackish and fresh waters. However, to date, no phylogenetic hypothesis exists for this widely distributed group. Here we turn to molecular data from the nuclear and mitochondrial genomes and combine these with the extensive fossil record of donacids to propose an evolutionary hypothesis for the family. Our analyses strongly support the monophyly of Donacidae, including Galatea, Iphigenia and ‘Plebidonax’ deltoides, but render Donax paraphyletic. The subgenus Latona is therefore elevated to genus to accommodate a clade of Indo-Pacific species, while retaining Donax for a clade of mostly Atlantic and American Pacific species, and a few Indo-Pacific species. This latter clade is sister group to Galatea + Iphigenia. The diversification of Donacidae seems to be tightly connected to the opening of the North and South Atlantic Oceans in the Cretaceous, and to the closing of the Tethys Ocean during the Oligocene.

Four species remain unidentified and eighteen represent new regional records, the total number of Conus species recorded from this archipelago now standing at fifty-three. Conus pacificus n.sp., from 295-600 m, and C. neptunus futunaensis n.ssp., from 370-455 m, are described.

Résumé [+] [-]Based on surveys conducted in the 1980s-1990s, especially the MUSORSTOM 9 expedition, we report on the bathymetric occurrences of 35 species of Conus in the Marquesas A rchipelago. Four are new records of shallow-water tropical Indo-Pacific species, and six are new species that were dredged, essentially from depths between 100 and 400 meters. The species classically found in deep water elsewhere in the South Pacific are strikingly absent from the Marquesas, and the local deep-water faunule is thus highly endemic. This study confirms the Marquesas as a biogeographically outstanding archipelago, with a rather poor, but unique, benthic fauna. New species: Conus tiki spec. Nov., C. dieteri spec. Nov., C. pepeiu spec. Nov. , C. troendlei spec. Nov., C. hivanus spec. Nov., and C. pseudimperialis spec. Nov.

Moolenbeek R.G., Röckel D. & Bouchet P. 2008. New records and new species of cones from deeper water off Fiji (Mollusca, Gastropoda, Conidae). Vita Malacologica 6: 35-49
Résumé [+] [-]A little less than 100 species of cones are known in the literature from waters around the Fiji islands, all intertidal to subtidal. We report here on the species taken by recent offshore and deep-water benthic sampling expeditions. Samples were taken to depths of 1300 m, although cones were taken not deeper than 680 m. Leaving aside two taxa of uncertain identity, the material contains 22 species from depths deeper than 100 m, all of which are new records for Fiji, including four new species (Conus cakobaui spec. nov., alive in 414- 567 m; C. joliveti spec. nov., alive in 150-353 m; C. fijisulcatus spec. nov., alive in 150-188 m; and C. gigasulcatus spec. nov., alive in 290-300 m). A further 19 species are from depths shallower than 100 m, and these include six new records for Fiji, including two new species (C. fijiensis spec. nov., alive in 80-120 m; and C. sutanorcum spec. nov., alive in 32-50 m).

Résumé [+] [-]Based on material stored in Museum National d'Histoire Naturelle (MNHN) eight new species collected from bathyal depths in South West Pacific archipelagos ( Solomon Islands and Fiji) are described. The new species belong to the rather poorly known genera Acanthodaphne Bonfitto et Morassi, 2006, Acamptodaphne Shuto, 1971, Buccinaria Kittl, 1887, Cryptodaphne Powell, 1942 and Mioawateria Vella, 1954 all belonging to subfamily Raphitominae Bellardi, 1875 in the family Conidae Fleming, 1822. Acamptodaphne eridmata sp. nov. has a broad distribution being reported from the Solomon Islands and Taiwan. Finding of the new species here discussed in South West Pacific archipelagos provides a significant extension to the previously known geographical range of these raphitomine genera.

Résumé [+] [-]Tudivasum Rosenberg & Petit, 1987 is a morphologically distinct gastropod genus of low diversity. All but one species are known from Australia and they occur from the intertidal zone down to hundreds of metres on the continental shelf. These carnivorous gastropods are thought to have intracapsular development. The six currently recognized extant species are reviewed here and their geographical ranges clarified. Two new species, Tudivasum chaneyi n. sp. and T. ashmorense n. sp., are described from Ashmore Reef, Western Australia, and are characterized by differences in protoconch colour and shell sculpture. The third new species, T. westrale n. sp., is described from the mid-west coast of Western Australia, where it has long been misidentified as T. spinosum (H. Adams & A. Adams, 1864). We generated a molecular phylogeny based on mitochondrial DNA sequence data to test morphological species concepts and reconstruct relationships among four of the described species. High levels of divergence within one of the new species could indicate an additional cryptic species.

Mémoires du Muséum national d'Histoire naturelle 172:357-383, ISBN:2-85653-506-2
Résumé [+] [-]Six mid-depth octopuses of the Order Octopoda are reported from the Banda and Arafura Seas off Indonesia and northern Australia, based on material collected through the collaborative French-Indonesian KARuBAR cmise of 1991. Octopod material was collected through benthic trawls at 18 of 91 stations, at depths between 199 and 869 metres. Two new species are described here, Benthoctopus karubar sp. nov. and Octopus pyrum sp. nov. An additional species of the genus Octopus is reported as indeterminate but distinct from O. pyrum. The genus Pteroctopus is reported from IndoPacifie waters for the first time, based on female material collected through the KARuBAR cmise and linked with additional male material collected off New Caledonia and Vanuatu. Eledone palari is recorded as a northerly extension to the Australian distribution reported in the original description for this species. A single submature female of the pelagie octopod, Haliphron atlanticus (previously treated under the name Alloposus mollis), is also reported from the region. The depth distributions and phylogenetic affinities of this fauna are discussed.

Résumé [+] [-]French and Australian research expeditions over the past three decades, to the deeper waters of the tropical Pacific Ocean, have encountered a distinctive new octopus. Galeoctopus lateralis is described here from 200-400 in deep in the southern and western Pacific Ocean. This small octopus is recognized by a distinctive jaw-like ligula in mature males, superficially resembling the head and jaws of a shark (complete with teeth-like lugs). Other distinctive characters include a lateral mantle ridge, skin sculpture including stellate papillae, and swollen distal oviducts in females. This combination of characters warrants recognition as a distinct genus. Relationships with other octopodid genera are discussed. We propose that the unique form of the male reproductive organ has evolved as a mechanism for reduction of sperm competition. The mouth-like ligula pit may function to pierce, rupture, grip and/or remove the sperm bulbs of previous suitors from the distal oviducts of the female. This morphology is compared with parallel structures in other cephalopods.

Résumé [+] [-]Deep-water trawl surveys on seamounts around New Caledonia yielded 62 specimens of the little-known genus, Scaeurgus. Members of this genus of octopuses typically occur at depths of 200-500 m in temperate and tropical latitudes worldwide. Prior to this study, Scaeurgus was considered to contain one to two species. The new material from New Caledonia contained a surprising diversity of Scaeurgus species from a small area: three distinct new species are described and limited material of a further two taxa is reported. A pygmy member of this genus is reported for the first time. Distributions of these new taxa are consistent with reports of high endemism on the seamount systems in this region. Fifty-eight of the 62 specimens were collected from seamounts, with four of the five taxa unique to a single seamount.

Résumé [+] [-]In recent years considerable media attention has been focussed on the "Mimic Octopus", an Indo-West Pacific long-armed species which impersonates numerous poisonous or dangerous animals. This distinctive octopus is here described. A combination of unique morphological characters justify this octopus being placed in a new genus. These characters include: absence of a calamus on the copulatory organ, absence of enlarged suckers in either sex; long narrow arms capable of arm autotomy at a set level near the base; and distinctive base components of colour patterns including a white teardrop ring on the mid-dorsal mantle and a distinct white "U" patch on the posterio-dorsal mantle. Thaumoctopus mimicus n. gen. et sp. is reported primarily from the Indo-Malayan Archipelago from New Caledonia to Indonesia, Malaysia and the Philippines. Photographic records from the Red Sea extend the distribution to the western Indian Ocean. This octopus occurs in shallow waters (0.5–37 m) on soft sediment substrates where it is day-active, foraging for small fish and crustaceans. It is delineated from other long-armed genera and species complexes within the genus Octopus. Other undescribed species are flagged as potential members of the new genus Thaumoctopus. Links between habitat preference and the origins of this unique mimicry are explored.

Résumé [+] [-]Trawl surveys off Western Australia and seamounts south of New Caledonia at depths between 375 and 545 m have yielded two species of a previously unknown genus of benthic octopus (Family: Octopodidae). Histoctopus n. gen. is described here and contains two new species, Histoctopus discus and Histoctopus zipkasae n. spp. The most distinctive morphological feature of this new genus is extreme web margin development along the length of the arms, widening towards the distal tips. Of all benthic octopuses, such web margin development only occurs in this new genus and three other distinct genera, Graneledone, Pteroctopus and Velodona (from comparable depths, typically >200 m). Due to significant morphological differences between these two genera and Histoctopus, we propose that the shared web margin development reflects convergence that is peculiar to a deeper-water habitat. The function of these web extensions remains unknown; they may aid in ensnaring or enveloping prey and/or provide lift while jet swimming off the seafloor.

Résumé [+] [-]A group of venomous turriform gastropods in the subfamily Turrinae, genus Lophiotoma, has been investigated. Previously, forms in this group were identified as either Lophiotoma unedo or Lophiotoma indica. Our analysis has led to the description of four new species from the Philippines (L. bisaya, L. friedrichbonhoefferi, L. panglaoensis, and L. tayabasensis) and one each from Australia (L. capricornica), South Africa/Mozambique (L. dickkilburni), and Madagascar (L. madagascarensis). A new subspecies, L. indica queenslandica, is also described. In addition, 11 distinctive forms related to these taxa that may or may not deserve separate taxonomic status are defined; these need further evaluation. It is hypothesized that the forms of Lophiotoma discussed in this report are closely related to a particular subset of Gemmula, the G. kieneri/G. interpolata group.

This coralliophiline fauna appears severely impoverished, compared to other West Pacifie areas. At least half of the species (seven) are members of the shallow water fauna, an unusual pattern for the prevalently deep water coralliophilines, which may indicate an increase with depth of the effects of marginality on benthie faunas. One new species Coralliophila nukuhiva n. sp. is here described.

Résumé [+] [-]This is a regional revision of the Coralliophilinae (Neogastropoda: Muricidae) from the southwest Pacifi c, based on the material collected during recent expeditions to New Caledonia (including the Coral Sea, mainland New Caledonia, and the Loyalty Islands), Vanuatu, Wallis and Futuna, Fiji and Tonga. It is the fi rst revision of a tropical coralliophiline fauna based on large and extensive sampling, and it yielded a total of 97 coralliophiline species, 13 of them new: Coralliophila candidissima n. sp., C. bathus n. sp., C. norfolk n. sp., C. xenophila n. sp., C. cancellarioidea n. sp., Babelomurex natalabies n. sp., B. pallox n. sp., B. depressispiratus n. sp., B. macrocephalus n. sp., Hirtomurex marshalli n. sp., Mipus tonganus n. sp., M. alis n. sp., and M. boucheti n. sp. A lectotype is selected for Purpura monodonta Blainville, 1832. In addition, this survey resulted in new biogeographical records for 37 species from the southwest Pacifi c fauna. Regional endemicity may be as high as 17.5% (17 out of 97 species). The protoconchs of 47 species are fi gured by SEM. At least 68 species have planktotrophic development, while 10 species are probably lecithotrophic, either with a short pelagic phase or with a totally intracapsular develoment.

Oliverio M. 2009. Diversity of Coralliophilinae (Mollusca, Neogastropoda, Muricidae) at Austral Islands (South Pacific). Zoosystema 31(4): 759-789
Résumé [+] [-]The Coralliophilinae is a large subfamily of Muricidae, including 200-250 species that feed exclusively on anthozoans. The material collected during the expeditions BENTHAUS and RAPA 2002 at Austral Islands are reviewed. Twenty-eigth species are recorded, one species is described as new, Coralliophila australis n. sp., diagnosed by its large size and elongated shape. All but one species showed a planktotrophic development, 10 species (36%) were from shallow waters and 15 species (54%) from deep waters. The smaller proportion of deep water coralliophiline species (compared to the range and average on a global scale) in this marginal area of the Pacific, suggests that marginality may affect the deep water faunas more than the shallow water ones.

Résumé [+] [-]The gastropod genus Colubraria includes marine shallow-water species from tropical, subtropical, and temperate rocky coral environments. At least six species are known to feed on fish blood. Although there is general consensus in placing Colubraria in the Neogastropoda, the actual relationships and the systematic position of Colubraria and related genera are unknown. This is partly the consequence of the lack of a clear phylogenetic framework for the Neogastropoda. This study attempts to propose a phylogenetic framework for the Neogastropoda, by testing: (1) a preliminary phylogenetic arrangement for a large number of recognized neogastropod families; (2) the position of Colubraria within the neogastropods; and (3) the relationships of Colubraria within one of the major neogastropod lineages. We used two different molecular data sets. The first set included representatives of at least 14 neogastropod families, for points (1) and (2), and was based on mitochondrial (16S, 12S, and cytochrome oxidase subunit I, COI) and nuclear (28S) DNA sequences, giving a total of 3443 aligned positions. The second data set, for point (3), included 30 buccinoid sequences from mitochondrial 16S, giving a total of 1029 aligned positions. We also studied the anatomy of the type species of Colubraria and compared it with other neogastropods within the new phylogenetic framework. The results included the first phylogeny of the neogastropod based on 50% of the recognized families. This clearly indicated that the nematoglossan Cancellariidae represent a basal offshoot of the monophyletic Neogastropoda, and that the toxoglossan Conoidea are the sister group to the Rachiglossa. Within the Rachiglossa, a colubrariid clade, worthy of family ranking, showed clear buccinoid affinities. Most of the anatomy of Colubraria is congruent with a buccinoid model. The peculiar anatomical features that do not conform to the buccinoid model seem to be related to the evolution of haematophagous feeding.

Résumé [+] [-]The genus Lamprohaminoea includes species of colourful haminoeid snails associated with coral reefs and rocky shores in the tropical Indo-West Pacific. In this work, we revise the diversity and systematics of Lamprohaminoea species based on a phylogenetic hypothesis and on a detailed morphological analysis of specimens. Shells, external features of the animals and anatomical characters from the jaws, radula, gizzard plates, and male reproductive system were studied by optical and scanning electron microscopy. Additionally, a molecular species delimitation analysis based on the Automatic Barcode Gap Discovery method using DNA sequences of the cytochrome c oxidase subunit I was implemented. Five species were recognised, three of them new to science, namely L. cymbalum, L. ovalis, L. vamiziensis sp. nov., L. evelinae sp. nov., and L. mikkelsenae sp. nov. Morphologically, these species can be separated by subtle differences of their external colouration and by features of the male reproductive system. Lamprohaminoea vamiziensis sp. nov. is known only from the western Indian Ocean and L. evelinae sp. nov., from the west Pacific, whereas the other three occur across the Indo-West Pacific realm.

Petit R.E. & Harasewych M.G. 1986. New Philippine Cancellariidae (Gastropoda: Cancellariacea), with Notes on the fine structure and function of the nematoglossan Radula. The Veliger 28(4): 436-443
Résumé [+] [-]Three new species of Cancellariidae, Cancellaria boucheti, C. atopodonta, and C. aqualica, are described, all from deep water oflf the western Philippines. The radula of two of these, C. boucheti and C. atopodonta, are figured, and a mechanism by which the cusps are interlocked is described. On the basis of mechanical considerations, we suggest that the function of the nematoglossan radula is limited to the penetration of tissues of prey organisms, in order to reach the internal fluids on which the cancellariids then feed suctorially.

Résumé [+] [-]This paper reports on deep water Pyramidellidae from the tropical South Pacific, collected during the Tropical Deep-Sea Benthos expeditions conducted by IRD and MNHN in New Caledonia, the Solomon Islands, Fiji, Tonga, Vanuatu, Wallis and Futuna, and French Polynesian, and deals more specifically with those species that can be included in the tribe Turbonillini. Since the different genera have not been thoroughly revised at the present time and there is no certainty about their validity, we have employed only the genus name Turbonilla in a broad sense. In total, 272 species are studied, of which 30 were already known, 33 were too poorly represented to be named and are presented as sp., and 209 are described as new to science. There is a clear decrease in species richness from the Solomon Islands (202 species) eastwards to Fiji (82 species), New Caledonia (85 species), Vanuatu (31 species), Tonga (11 species) and the Marquesas (7 species). Replacement names are proposed for Turbonilla gracilis (A. Adams, 1854) non Turbo gracilis Brocchi, 1814, and Exesilla sulcata Laseron, 1959, non Odostomia sulcata Garrett, 1873, both secondary homonyms in Turbonilla. New taxonomic opinions in this work are the following: Turbonilla theresa Thiele, 1925 and Pyrgiscus mirandus Saurin, 1959 are considered synonyms of Turbonilla funiculata de Folin, 1868; Odontostomia robusta Hedley, 1899, Turbonilla microscopica Laseron, 1959, and Turbonilla (Pyrgostelis) manorae Melvill, 1898 are considered synonyms of Turbonilla mumia (A. Adams, 1861); Turbonilla decussata Pease, 1861, T. elongata Pease, 1868, Proto cornelliana Newcomb, 1870, Chemnitzia coppingeri E. A Smith, 1884, Turbonilla (Lancella) bella Dall & Bartsch, 1906, and Turbonilla (Lancella) vitiensis Pilsbry, 1917 are considered synonyms of Turbonilla varicosa (A. Adams, 1855); Elusa secunda Saurin, 1959 is a synonym of Turbonilla ovalis de Folin, 1868; Turbonilla multigyrata Dunker, 1882 is a synonym of T. candida A. Adams, 1855; Turbonilla lydia Thiele, 1925 is a synonym of Turbonilla crystallina Dall & Bartsch, 1906.

Lack of Signal for the Impact of Conotoxin Gene Diversity on Speciation Rates in Cone Snails, in Serb J.(Ed.), Systematic Biology 68(5): 781-796. DOI:10.1093/sysbio/syz016
Résumé [+] [-]Abstract Understanding why some groups of organisms are more diverse than others is a central goal in macroevolution. Evolvability, or the intrinsic capacity of lineages for evolutionary change, is thought to influence disparities in species diversity across taxa. Over macroevolutionary time scales, clades that exhibit high evolvability are expected to have higher speciation rates. Cone snails (family: Conidae, $>$900 spp.) provide a unique opportunity to test this prediction because their toxin genes can be used to characterize differences in evolvability between clades. Cone snails are carnivorous, use prey-specific venom (conotoxins) to capture prey, and the genes that encode venom are known and diversify through gene duplication. Theory predicts that higher gene diversity confers a greater potential to generate novel phenotypes for specialization and adaptation. Therefore, if conotoxin gene diversity gives rise to varying levels of evolvability, conotoxin gene diversity should be coupled with macroevolutionary speciation rates. We applied exon capture techniques to recover phylogenetic markers and conotoxin loci across 314 species, the largest venom discovery effort in a single study. We paired a reconstructed timetree using 12 fossil calibrations with species-specific estimates of conotoxin gene diversity and used trait-dependent diversification methods to test the impact of evolvability on diversification patterns. Surprisingly, we did not detect any signal for the relationship between conotoxin gene diversity and speciation rates, suggesting that venom evolution may not be the rate-limiting factor controlling diversification dynamics in Conidae. Comparative analyses showed some signal for the impact of diet and larval dispersal strategy on diversification patterns, though detection of a signal depended on the dataset and the method. If our results remain true with increased taxonomic sampling in future studies, they suggest that the rapid evolution of conid venom may cause other factors to become more critical to diversification, such as ecological opportunity or traits that promote isolation among lineages.

Résumé [+] [-]This regional revision of the family Caecidae from the South-West Pacific, is based on material collected during oceanographic expeditions made by the Muséum National d’Histoire Naturelle (Paris) from 1976 to 2006. The material consists of about 8250 specimens from 208 stations. In addition, material from the Australian Museum (Sydney) (94 lots) and the Western Australian Museum (Perth) (42 lots), and other specimens from private collections, were used. In the present work, 43 species are dealt with, belonging to the genera Caecum (31), Meioceras (4), Parastrophia (6) and Strebloceras (2). Two genera, Gladioceras and Ctiloceras, were not dealt with because of the absence of related material. These are the sole genera considered valid on the basis of their distinct type of development. Of these species, 18 are described as new. An extensive usage of type material was done for comparisons, either on directly or by means of photographs. Lectotypes were selected for Strebloceras cornuoides Carpenter, 1859†, C. chinense Folin, 1868, C. modestum Folin, 1868, C. sepimentum Folin, 1868, C. succineum Folin, 1880, C. bimarginatum Carpenter, 1858, C. inflatum Folin, 1869, C. attenuatum Folin, 1880, M. legumen Hedley, 1899, Parastrophia cornucopiae (Folin, 1869) and Strebloceras subannulatum Folin, 1879.

Résumé [+] [-]The 25 Recent species and subspecies of the Xenophoridae are reviewed. Three sub genera are recognized within the only genus, Xenophora: Stellaria (with 5 species and 1 subspecies), Onustus (with 4 species), and Xenophora s.s. (with 13 species and 2 subspecies). A brief outline of the fossil history of the group and a general account of the anatomy and habits are given. A new species (X. granulosa sp. nov.) from the central Indo-Pacific and three new subspecies are described, one from the Hawaiian Islands (X. peroniana kondoi subsp. Nov.), one from the Gulf of Aden (X. testigera profunda subsp. Nov.), and one from the Kermadec Islands (X. neozelanica kermadecensis subsp. Nov.). The fossil Xenophora known from Australia are reviewed and a new Upper Pliocene - Lower Pleistocene subspecies (X. flindersi ludbrookae subsp. Nov.) and an unnamed Upper Cretaceous species are described. The shell, and where known the radula, operculum and anatomy, are described for each species. The distribution and synonymy of each species is also given in detail. All of the speciesgroup names of fossil Xenophota are listed (Appendix, with J. Cooper). Fossil species occurring outside Australia are not revised with the exception of a few which have relevance to the taxonomy of Recent species.

Résumé [+] [-]Seguenzioidea and Trochoidea are substantial parts of the biodiversity in the Indo-Pacific. While many Japanese, Australian, New Caledonian and New Zealand species have been studied and described recently, these superfamilies remain unsatisfactory known in the Philippines. Modern collecting resulted in the discovery of many new species. Others are well presented in collections worldwide but most often they bear names of mainly Japanese species, occasionally of Australian or Indian Ocean species. These names have been used as "megaspecies-names" for a vast part of the Indo-Pacific mollusca. We here document 178 species collected in the Philippines, either by Conchology, Inc. Or the Museum National d'Histoire Naturelle, Paris (hereafter referred to as MNHN). The first author is a fan of Trochidae since three decades, from where this publication, which is the result of three years collecting by hundreds of fisherman, scientists and divers. We therefore enlighten this book with photographs of the area, the events, living animals and the people.

Résumé [+] [-]The two new species described in this paper are widely distributed in the tropical south-western Pacific; they have been found on the upper continental shelf of the area, around New Caledonia, westward to Chesterfield Islands and Lord Howe Ridge, southward to northern part of Norfolk Ridge, north- and eastward to Vanuatu, Fiji and Tonga islands. They belong to two often confused genera of subfamily Protocardiinae (sensu Keen 1980), Frigidocardium Habe, 1951 and Microcardium Th iele, 1934, that are briefly characterized herein. Frigidocardium valdentatum n. sp. is characterized by the peculiar sculpture of mid-posterior slope ending in strongly dentate margin. Frigidocardium kirana is a similar species with lower outer sculpture, more asymmetrical shape and rather strong umbonoventral fold; it is first recorded here from the tropical Southwest Pacific and Mascarene islands. Diagnostic features of Microcardium trapezoidale n. sp. include rather high trapezoidal shape and posterior sculptural area extending on 2/5 of shell length, with an anterior limit almost parallel to radial ribs in the adult and well-developed, non lamellous sculpture in the rib interstices. A comparative review of all Recent Microcardium species in the Indo-West Pacific is given, to place the new species in the context of the genus. Five Microcardium species are presently known in this area: M. gilchristi from southern Africa, M. simillimum n. comb. (for Cardium (Fragum) simillimum) from Sri Lanka and Mascarene Plateau, M. sakuraii from Japan and the Philippines (new record), M. aequiliratum from the Philippines, and M. tenuilamellosum from the Philippines and Solomon Islands (new record).

Résumé [+] [-]The superfamily Conoidea is one of the most speciose groups of marine mollusks, with estimates of about 340 recent valid genera and subgenera, and 4000 named living species. Previous classifications were based on shell and anatomical characters, and clades and phylogenetic relationships are far from well assessed. Based on a dataset of ca. 100 terminal taxa belonging to 57 genera, information provided by fragments of one mitochondrial (COI) and three nuclear (28S, 18S and H3) genes is used to infer the first molecular phylogeny of this group. Analyses are performed on each gene independently as well as for a data matrix where all genes are concatenated, using Maximum Likelihood, Maximum Parsimony and Bayesian approaches. Several well-supported clades are defined and are only partly identifiable to currently recognized families and subfamilies. The nested sampling used in our study allows a discussion of the classification at various taxonomical levels, and several genera, subfamilies and families are found polyphyletic.

Résumé [+] [-]DNA sequences are currently used to propose primary hypotheses of species delimitation, especially when morphological variability is difficult to assess. In an integrative taxonomy framework, these hypotheses are then compared with other characters, such as morphology or geography, to produce robust species delimitations. For this purpose, the cytochrome oxidase subunit I (COI) gene has been sequenced for almost 50 specimens of the genus Benthomangelia, a deep-sea marine gastropod genus, collected in the South-West Pacific. Five genetic groups, displaying low and high genetic distances respectively within and between groups, were defined. COI hypotheses were compared with both the results obtained with the independent nuclear 28S gene and with an elliptic Fourier analysis of the shape of the last whorl of the shell. 28S gene analysis confirmed the same well-supported groups as COI, and elliptic Fourier analysis identified several morphological characters that vary similarly to genetic variability.

Résumé [+] [-]Identifying life stages of species with complex life histories is problematic as species are often only known and/or described from a single stage. DNA barcoding has been touted as an important tool for linking life-history stages of the same species. To test the current efficacy of DNA barcodes for identifying unknown mollusk life stages, 24 marine gastropod egg capsules were collected off the Philippines in deep water and sequenced for partial fragments of the COI, 16S and 12S mitochondrial genes. Two egg capsules of known shallow-water Mediterranean species were used to calibrate the method. These sequences were compared to those available in GenBank and the Barcode of Life Database ( BOLD). Using COI sequences alone, only a single Mediterranean egg capsule was identified to species, and a single Philippine egg capsule was identified tentatively to genus; all other COI sequences recovered matches between 76% and 90% with sequences from BOLD and GenBank. Similarity-based identification using all three markers confirmed the Mediterranean specimens' identifications. A phylogenetic approach was also implemented to confirm similarity-based identifications and provide a higher-taxonomic identification when species-level identifications were not possible. Comparison of available GenBank sequences to the diversity curve of a well-sampled coral reef habitat in New Caledonia highlights the poor taxonomic coverage achieved at present in existing genetic databases, emphasizing the need to develop DNA barcoding projects for megadiverse and often taxonomically challenging groups such as mollusks, to fully realize its potential as an identification and discovery tool.

Résumé [+] [-]The superfamily Conoidea is one of the most speciose groups of marine molluses, with almost 700 genera and 10,000 living species. Previous classifications were based on morphological and anatomical characters, but clades and phylogenetic relationships were not well assessed. Information provided by one mitochondrial (COI) and three nuclear (28S, 18S, and H3) genes were used to infer the phylogeny of this group. Data were obtained from more than 100 specimens, belonging to 54 genera, collected during recent cruises in the western Pacific (Philippines, Vanuatu, Norfolk Ridge, and Chesterfield and Solomon Islands). Analyses were performed on each gene independently as well as for a data matrix where all genes were concatenated, using several methods (ML, Parsimony, Bayesian). Some families and subfamilies among Conoidea correspond to well-supported clades uniformly recovered with all genes and all methods, but others appear to be polyphyletic. Several bathyal and abyssal genera are also shown to he polyphyletic. Our results also point out some new phylogenetic relationships at the family, subfamily, and genus levels.

Résumé [+] [-]During a broad molecular taxonomic and phylogenetic survey of the gastropod superfamily Conoidea, 80 specimens of several species of the genus Gemmuloborsonia were sequenced for the cytochrome c oxidase subunit I gene. The genus, originally established for fossil species from the Plio-Pleistocene of the Philippines, now includes living species from bathyal depths of the Indo-Pacific Oceans. The molecular data demonstrated the presence of five separate entities, while only four ‘morphospecies’ could be isolated by visual examination. The two largest groups, representing separate species from the molecular data, were impossible to distinguish with certainty using shell or anatomical characters. To examine shell morphology in more detail the shape of the last whorl was analysed by Fourier analysis, and the Fourier coordinates were used in canonical variate analysis. The majority of the specimens were separated into two groups, but 21.6% of the specimens were impossible to distinguish by morphological characters. One of these two forms was attributed to the known species Gemmuloborsonia moosai Sysoev & Bouchet, 1996, while the other is described as a new species Gemmuloborsonia clandestina. Bathytoma colorata Sysoev & Bouchet, 2001 is transferred to Gemmuloborsonia on the basis of molecular analysis and radular morphology. Another species, represented in our material by a single specimen, remains undescribed.

DOI:10.1080/14772001003748709
Résumé [+] [-]Dispersal capabilities are crucial in how speciation patterns are determined in marine invertebrates. Species possessing a long-living planktonic larva apparently have a dispersal advantage over those with non-planktotrophic development, and their distant populations may exchange genetic material, maintaining a broad geographical range for the species. Recent species of the gastropod genus Bathytoma (Conoidea) are all characterized by non-planktotrophic development, having most probably lost a free-swimming larva in the pre-Pliocene, as Miocene fossils have protoconchs indicating planktotrophic larval development. All have a bathyal distribution (100–1500 m), which implies that their capability for direct expansion on the bottom is restricted by both deep-sea basins and shallow-water areas, especially in insular West and South-West Indo-Pacific. Therefore, it can be hypothesized that Bathytoma populations should represent numerous, mostly allopatric taxa restricted to a single or contiguous island groups. We tested this hypothesis using molecular and morphological characters independently. One hundred and thirty-eight specimens from the Philippines, Solomons, Vanuatu, and the Coral Sea were sequenced for one mitochondrial (COI) and one nuclear (ITS2) gene, and 14 operational molecular units were recognized. When these molecular units are overlaid over shell characters, 13 species (11 unnamed) and one form of uncertain status are recognized: three occur in the Philippines, six in the Solomons and one in New Caledonia. Broad distributions (inter-archipelagic) are uncommon (three species). On the whole, the phylogeographic pattern of the diversity in the genus is rather complex and probably also reflects processes of sympatric and fine-scale allopatric speciation, and local extinctions. The eleven new species are described and named.

Résumé [+] [-]The cone snails (family Conidae) are a hyperdiverse lineage of venomous gastropods. Two standard markers, COI and ITS2, were used to define six genetically divergent groups within a subclade of Conidae that includes Conus orbignyi; each of these was then evaluated based on their shell morphology. We conclude that three forms, previously regarded as subspecies of C. orbignyi are distinct species, now recognized as C. orbignyi, C. elokismenos and C. coriolisi. In addition, three additional species (C. pseudorbignyi, C. joliveti and C. comatosa) belong to this clade. Some of the proposed species (e. g. C. elokismenos) are possibly in turn complexes comprising multiple species. Groups such as Conidae illustrate the challenges generally faced in species delimitation in biodiverse lineages. In the case of C. orbignyi complex, they are not only definable, genetically divergent lineages, but also considerable geographical variation within each group. Our study suggests that an intensive analysis of multiple specimens within a single locality helps to minimize the confounding effects of geographical variation and can be a useful starting point for circumscribing different species within such a confusing complex.

Résumé [+] [-]The superfamily Conoidea constitutes one of the most diverse and taxonomically challenging groups among marine molluscs. Classifications based on shell or radular characters are highly contradictory and disputed. Whereas the monophyly of the Conidae and Terebridae has not been challenged, the other constituents of the superfamily are placed in a 'trash' group, the turrids, the non-monophyly of which has been demonstrated by anatomical and molecular evidence. We present here a new molecular phylogeny based on a total of 102 conoidean genera (87 'turrids', 5 cones and 10 terebrids) and three mitochondrial genes [cytochrome oxidase I (COI), 12S rRNA and 16S rRNA]. The resulting tree recognizes 14 clades. When the Conidae (Conus s.l.) and Terebridae are ranked as families for consistency of usage, the 'turrids' must be split into 12 families of comparable rank. A new genus-level classification of the Conoidea is published in an accompanying paper.

Résumé [+] [-]Accelerating the description of biodiversity is a major challenge as extinction rates increase. Integrative taxonomy combining molecular, morphological, ecological and geographical data is seen as the best route to reliably identify species. Classic molluscan taxonomic methodology proposes primary species hypotheses (PSHs) based on shell morphology. However, in hyperdiverse groups, such as the molluscan family Turridae, where most of the species remain unknown and for which homoplasy and plasticity of morphological characters is common, shell-based PSHs can be arduous. A four-pronged approach was employed to generate robust species hypotheses of a 1000 specimen South-West Pacific Turridae data set in which: (i) analysis of COI DNA Barcode gene is coupled with (ii) species delimitation tools GMYC (General Mixed Yule Coalescence Method) and ABGD (Automatic Barcode Gap Discovery) to propose PSHs that are then (iii) visualized using Klee diagrams and (iv) evaluated with additional evidence, such as nuclear gene rRNA 28S, morphological characters, geographical and bathymetrical distribution to determine conclusive secondary species hypotheses (SSHs). The integrative taxonomy approach applied identified 87 Turridae species, more than doubling the amount previously known in the Gemmula genus. In contrast to a predominantly shell-based morphological approach, which over the last 30 years proposed only 13 new species names for the Turridae genus Gemmula, the integrative approach described here identified 27 novel species hypotheses not linked to available species names in the literature. The formalized strategy applied here outlines an effective and reproducible protocol for large-scale species delimitation of hyperdiverse groups.

Résumé [+] [-]We present a large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes (COI, 16S rDNA and 12S rDNA). This is the first phylogeny of the taxon to employ concatenated sequences of several genes, and it includes more than twice as many species as the last published molecular phylogeny of the entire group nearly a decade ago. Most of the numerous molecular phylogenies published during the last 15 years are limited to rather small fractions of its species diversity. Bayesian and maximum likelihood analyses are mostly congruent and confirm the presence of three previously reported highly divergent lineages among cone snails, and one identified here using molecular data. About 85% of the species cluster in the single Large Major Clade; the others are divided between the Small Major Clade (12%), the Conus californicus lineage (one species), and a newly defined clade (3%). We also define several subclades within the Large and Small major clades, but most of their relationships remain poorly supported. To illustrate the usefulness of molecular phylogenies in addressing specific evolutionary questions, we analyse the evolution of the diet, the biogeography and the toxins of cone snails. All cone snails whose feeding biology is known inject venom into large prey animals and swallow them whole. Predation on polychaete worms is inferred as the ancestral state, and diet shifts to molluscs and fishes occurred rarely. The ancestor of cone snails probably originated from the Indo-Pacific; rather few colonisations of other biogeographic provinces have probably occurred. A new classification of the Conidae, based on the molecular phylogeny, is published in an accompanying paper.

When everything converges: Integrative taxonomy with shell, DNA and venomic data reveals Conus conco, a new species of cone snails (Gastropoda: Conoidea). Molecular Phylogenetics and Evolution 80: 186-192. DOI:10.1016/j.ympev.2014.06.024
Résumé [+] [-]Cone snails have long been studied both by taxonomists for the diversity of their shells and by biochemists for the potential therapeutic applications of their toxins. Phylogenetic approaches have revealed that different lineages of Conus evolved divergent venoms, a property that is exploited to enhance the discovery of new conotoxins, but is rarely used in taxonomy. Specimens belonging to the Indo-West Pacific Conus lividus species complex were analyzed using phenetic and phylogenetic methods based on shell morphology, COI and 28S rRNA gene sequences and venom mRNA expression and protein composition. All methods converged to reveal a new species, C. conco n. sp. (described in Supplementary data), restricted to the Marquesas Islands, where it diverged recently (_3 mya) from C. lividus. The geographical distribution of C. conco and C. lividus and their phylogenetic relationships suggest that the two species diverged in allopatry. Furthermore, the diversity of the transcript sequences and toxin molecular masses suggest that C. conco evolved unique toxins, presumably in response to new selective pressure, such as the availability of new preys and ecological niches. Furthermore, this new species evolved new transcripts giving rise to original toxin structures, probably each carrying specific biological activity.

Résumé [+] [-]Mollusks are an invaluable resource in the Philippines, but recent reviews on the status of museum collections of mollusks or research trends in the country are lacking. Such assessments can contribute to a more comprehensive evaluation of natural history museums in the Philippines, as well as biodiversity management. This review showed that local museums in the Philippines have much to improve in terms of their accessibility and geographic coverage in order to effectively cater to research and conservation needs of the country. Online access to databases was lacking for local museums, making it cumbersome to retrieve collection information. The UST museum held the most species and subspecies across all museums (4899), comparable to the national museums of countries such as the USA and France. In terms of size, there were larger Philippine mollusk collections in museums abroad. Majority of mollusk specimens come from Regions 4 and 7, while the CAR and Region 12 were least sampled. Publications on Philippine mollusks are dominated by taxonomic and biodiversity research. Around 80% of publications were on marine species. Therefore, there is a great need to (1) improve access to collections by publishing databases and collections online; (2) improve spatial coverage of mollusk sampling to have a better nationwide (and habitat) representation of Philippine mollusk diversity; (3) fill important knowledge gaps in the ecological assessment of exploited mollusks and minor taxa that will be useful in status assessment and management; and (4) build a network of functional museums to facilitate mollusk and invertebrate researches and conservation by making properly curated specimens available to more researchers nationwide.

Ten species (Conus boucheti, C. kanakinus, C. luciae, C. plinthis, C. richeri, and the five new ones) are so far only known from the New Caledonia region and may be endemic. Conus smirna and C. profundorum are regarded as distinct, and two additional species are described in this species complex: C. vaubani sp. Nov., from South of New Caledonia and of the New Hebrides Arc in 440-775 m; and C. loyahiensis sp. Nov. From the Loyalty Islands in 480-575 m. Three other new species, and one subspecies, are named: Conus alisi sp. Nov. From the New Caledonia area, in 200-525 m; C. estivali sp. Nov. From the Chesterfield Islands, Coral Sea, in 355-410 m; C. gondwanensis sp. Nov. From the Norfolk Ridge, South New Caledonia, in 170-260 m; and C. orbignyi coriolisi ssp. Nov., from the Coral Sea, New Caledonia and Loyalty Islands, in 225-550 m.

Résumé [+] [-]The distribution of marine molluscs in each of the five archipelagos composing French Polynesia is presented with reference to 2053 species perfectly identified to the specific rank. The progress of knowledge on the distribution of molluscs and the limits of the inventory presented are discussed in relation to the reality of biodiversity. The species richness by archipelago is established and shows a degree of impoverishment along a longitudinal axis, from the Society to the Tuamotu and the Gambier, and along a latitudinal axis from north to south, from the Marquesas to the Society and the Austral. The distribution of species of marine molluscs allows to establish the species specific to each archipelago and those that are common to two or more archipelagos, which together determine the affinities between the archipelagos. The Marquesas and the Austral are very original in comparison with the Society, while the Tuamotu and even the Gambier are only impoverished faunas of the Society. The endemism in French Polynesia is 11.8 % (243 endemics out of 2053 species identified). Beyond this regional rate we can precise by archipelago two levels of endemism: that which is strict for the species whose distribution is limited to this archipelago and that which includes all the endemics, the strict ones and those present in at least one other archipelago: Marquesas (9.3 and 13.6 %) - Austral (6.8 and 12 %) - Society (2 and 6.5 %) - Tuamotu (2.3 and 7.9 %) - Gambier , 7 and 4.8 %). The richness of the marine mollusc fauna of French Polynesia is compared with that of Hawaii and the islands and archipelagos of the Eastern Pacific (Clipperton, Galapagos, Easter Island) and their high levels of endemism; respectively: 11, 8 - 20 - 4 - 17 and 42 %. The origin of the Polynesian marine mollusc fauna is evoked in relation to the Indonesian-Australian zone of maximum species richness with the confirmation that it operates since the Miocene as a center of dispersion creating at the margin of the Indo-Pacific province high places of speciation and endemism.

Résumé [+] [-]Molecular data were used to study the diversity of mytilids associated with sunken-woods sampled in the Solomon Islands and discuss the 'wooden steps to deep-sea vent' hypothesis proposed by Distel et al. First, COI data used in a barcoding approach confirm the presence of four distinct species. Analyses of the 18S rDNA and COI dataset then confirmed that these sunken-wood mytilids belonged to a monophyletic group including all species from deep-sea reducing environments. Finally, we analyzed the relationships within this monophyletic group that include the Bathymodiolinae using a COI dataset and a combined analysis of mitochondrial COI and ND4 genes and nuclear rDNA 18S and 28S. Our study supported the 'wooden steps to deep-sea vent' hypothesis: one of the sunken-wood species had a basal position within the Bathymodiolionae, and all described vent and seep mussels included in our analyses were derived taxa within Bathymodiolinae.

Résumé [+] [-]Bursa granularis (Röding, 1798) is a tonnoidean gastropod that is regarded as broadly distributed throughout the Indo-Pacific and tropical western Atlantic. Because of its variable shell it has received no less than thirteen names, now all synonymized under the name B. granularis. We sequenced a fragment of the cox1 gene for 82 specimens covering a large part of its distribution and most type localities. Two delimitation methods were applied, one based on genetic distance (ABGD) and one based on phylogenetic trees (GMYC). All analyses suggest that specimens identified as B. granularis comprise four distinct species: one limited to the tropical western Atlantic, another to southwestern Western Australia and two in the Indo-Pacific (from the Red Sea to the open Pacific) that are partly sympatric—but not syntopic—in Japan, the Philippines, Vanuatu and New Caledonia. Based on comparison of shell characters, we applied the following available names to the four species, respectively: B. cubaniana (d’Orbigny, 1841), B. elisabettae Nappo, Pellegrini & Bonomolo, 2014, B. granularis s. s. and B. affinis Broderip, 1833. We provide new standardized conchological descriptions for each of them. Our results demonstrate that a long planktotrophic larval stage, common among Tonnoidea, does not necessarily ensure a circumtropical species distribution.

Résumé [+] [-]Bursidae Thiele, 1925 is a moderately diverse group of extant tonnoidean gastropods with a significant fossil record. We review the fossil record of the family. We exclude some taxa from Bursidae, particularly the most ancient ones: Hanaibursa aquilana (Parona, 1909) (Aptian) and Bursa saundersi Adegoke, 1977 (Selandian). We exclude the genus Olequahia Stewart, 1926; its posterior siphonal canal is not analogous with that of Bursidae. We also discuss the possible revision of the type genus, Bursa Röding, 1798, on the basis of previously published phylogenies; the genus is not monophyletic. We create two new genera, Olssonia n. gen. (type species: Bursa chira Olsson, 1930) and Aquitanobursa n. gen. (type species: Ranella grateloupi d’Orbigny, 1852), containing only fossil species. Lectotypes are designated for Ranella grateloupi d’Orbigny, 1852, Ranella morrisi d’Archiac & Haime, 1853 and Apollon pelouatensis Cossmann & Peyrot, 1924. Based on this revision of the fossil record, we propose five fossil calibration points that can be used to date molecular phylogenetic trees of Bursidae.

Résumé [+] [-]With 59 Recent species, Bursidae, known as «frog shells», are a small but widely distributed group of tropical and subtropical gastropods that are most diverse in the Indo-West Pacific. The present study is aimed at recon structing phylogenetic relationships of bursid gastropods based on extensive and representative taxon sampling. Five genetic markers (cytochrome c oxidase subunit I (cox1), 16 s and 12 s rRNA mitochondrial genes, 28 s rRNA and Histone H3 nuclear gene) were sequenced for over 30 species in every known genus but Crossata. Furthermore, we sequenced the complete mt-genome of 9 species (10 specimens) (Aspa marginata, Marsupina bufo, Korrigania quirihorai, Korrigania fijiensis, Tutufa rubeta, Bursa lamarckii, Lampasopsis rhodostoma (twice), Bufonaria perelegans and Bursa aff. tuberosissima). Our analysis recovered Bursidae as a monophyletic group, whereas the genus Bursa was found to be polyphyletic. The genera Talisman and Dulcerana are resurrected and the genera Alanbeuella gen. nov. and Korrigania gen. nov. are described. Dating analysis using 21 extinct taxa for node and simplified tip calibrations was performed, showing a diversification of the group in two phases. Diversification may be linked to tectonic events leading to biodiversity relocation from the western Tethys to ward the Indo-Pacific.

Résumé [+] [-]Previous work that recorded 75 species of Scaphopoda in New Caledonian waters is augmented with study of new material from several expeditions. The number of species in the region is increased to 115. Of the 40 additional taxa, 28 are described as new, 7 are new records and 5 remain unidentifi ed. Material from New Caledonia previously identifi ed as Antalis phaneum (Dall, 1895) is now determined as A. albatrossae n. sp.; material previously identifi ed as Compressidentalium sedecimcostatum (Boissevain, 1906) is now determined as C. clathratum (Martens, 1881); Episiphon virgula (Hedley, 1903), formerly treated as a synonym of Dentalium subrectum Jeffreys, 1883, is revalidated; material previously identifi ed as Entalina mirifi ca (Smith, 1895) is now determined as E. dorsicostata Lamprell & Healy, 1998; Fissidentalium transversostriatum (Boissevain, 1906), previously synonymized with F. shoplandi (Jousseaume, 1894), is revalidated and the material previously reported from New Caledonia as the latter in fact belongs to the former. New synonyms: Episiphon jamiesoni Lamprell & Healy, 1998 is synonymized with Gadilina insolita (Smith, 1894); Dentalium subrectum Jeffreys, 1883 and D. bisinuatum André, 1896 are synonymized with Laevidentalium eburneum (Linné, 1767); Laevidentalium arnoldi Lamprell & Healy, 1998 is synonymized with L. houbricki Scarabino, 1995; Bathoxiphus steineri Lamprell & Healy, 1998 and B. stanisici Lamprell & Healy, 1998 are synonymized with Solenoxiphus striatulus Chistikov, 1983. New records from the New Caledonian region: Striodentalium thetidis (Hedley, 1903), Fissidentalium waterhousae Lamprell & Healy, 1998, Calliodentalium crocinum (Dall, 1907), Gadilina pachypleura (Boissevain, 1906), Laevidentalium eburneum (Linné, 1767), Laevidentalium (?) sominium Okutani, 1964, Megaentalina mediocarinata (Boissevain, 1906).

Résumé [+] [-]Heteroschismoides is a deep-sea genus characterized by shells being between 10 and 20 mm as adults, sculptured by 9 to 10 prominent primary ribs and a unique deep irregular apical fissure on dorsal side, considered until now to include a single species: Dentalium subterfissum Jeffreys, 1877. During revision of material from several expeditions carried out by the Museum National d’Histoire Naturelle, Paris, two new species were identified and are here described: H. meridionalis new species and H. antipodes new species In addition, designation of the lectotype of H. subterfissus is proposed, as well as new records for this species in the northeastern Atlantic ocean are given. Heteroschismoides meridionalis new species is closely related to H. subterfissus, but the first has a smaller maximum diameter of shell and smaller apical aperture diameter. Heteroschismoides antipodes new species from Solomon Islands is smaller than other two species for both, shell length and fissure extension. The distance of point of maximum curvature from the apex in H. antipodes new species is located nearer to the apex than in H. meridionalis new species and H. subterfissus. The results here obtained considerably enlarge the geographical distribution of the genus and suggest a worldwide bathyal and abyssal distribution for this genus.

The new genus is named Boissevainia n. gen. and the new species are Paradentalium choneides n. sp., P. danielleae n. sp., Fustiaria electra n. sp., F. diaphana n. sp., Gadilina lauensis n. sp., Episiphon joanae n. sp., E. wallisi n. sp., E. indefensum n. sp., E. kantori n. sp., E. lacteum n. sp. (Dentaliida); Bathoxiphus kathieae n. sp., Annulipusellum aenigmaticum n. sp. and Boissevainia mossiae n. gen., n. sp. (Gadilida). The new taxa not only highlight the diversity of the class in the tropical Pacific Ocean, but also indicate the presence of morphologies not yet recorded for the region or described for the class.

Résumé [+] [-]New data on the scaphopod fauna of the Indo-West Pacific are presented, based on new material from recent oceanographic expeditions, mostly in the SW Indian Ocean, SE Asia and the New Caledonia region. Over 780 stations yielded a total of 139 species. Of 81 species of Dentaliida and 58 Gadilida, 42 species (16 Dentaliida and 26 Gadilida), as well as 3 gadilid genera, are described as new. Many range extensions are documented, and new synonymies are established. With 73 recorded species, New Caledonia is currently the geographic area with the highest documented scaphopod diversity. Their bathymetric distribution shows a peak in species numbers in deep water around 800 m, with a second, minor peak for Gadilida at around 2,000 m. Including genera not represented in the Indo-Pacific, 44 Recent scaphopod genera are recognized. The radula of 42 of these is described, and an update of the general classification of the class Scaphopoda is proposed.

Résumé [+] [-]A compiled list of Fiji Islands chitons, including an updated chresonymy list and identification key, is provided. To the nine species previously known from the literature ten more are added. Of the 19 species now known from Fijian waters, one is a deep-water species and two are also known from fossils. A redescription of Callochiton neocaledonicus Kaas & Van Belle, 1990, and a detailed description of subadult specimens of Choneplax littlerorum Sirenko, 2003 are herein provided. Chiton spinosetatus Bergenhayn, 1930 is here regarded as a synonym of Chiton subassimilis Souverbie in Souverbie & Montrouzier, 1866. A lectotype designation is herein made for one of the numerous syntypes of Cryptoplax jugosus Bergenhayn, 1930 and for one of the two syntypes of Chiton reticulatus Nierstrasz, 1905 to stabilize the type localities for these species. For the same reason, and to clarify the confusing type status of Lepidopleurus niasicus Thiele, 1906, a lectotype is also selected from the three available syntypes. Acanthopleura nigropunctata Carpenter, 1865 and Tonicia novemrugata Bergenhayn, 1930, formerly placed in Tonicia, are both reassigned to the genus Lucilina on the basis of radular differences of both genera (second lateral tooth quadricuspid in Lucilina vs. unicuspid in Tonicia) and the geographic isolation of the Tonicia, of which species occur in central and south American waters only.

Résumé [+] [-]We present the most comprehensive phylogeny of a globally distributed deep-sea group of gastropods published to date including over 80% of the recognized diversity of the family Scaphandridae. The definition and taxo nomic composition of the Scaphandridae has been hampered by the lack of a sound phylogenetic framework and definition of synapomorphic traits. We used a combination of molecular phylogenetics (Bayesian Inference and Maximum Likelihood) based on five gene markers (cytochrome c oxidase subunit I, 12S rRNA, 16S rRNA, 18S rRNA, and 28S rRNA) and morpho-anatomical characters to redefine the Scaphandridae and its genera. A new classification is proposed with the three genera Nipponoscaphander, Sabatia, and Scaphander. Main differences between genera lie on the shells (shape, parietal callus, spire) and male reproductive system (prostate). The species Hamineobulla kawamurai is reassigned to the closely related family Eoscaphandridae, currently defined mostly based on pleisiomorphic traits. Biogeographically the genus Nipponoscaphander is restricted to the IndoWest Pacific; Sabatia is mostly circumscribed to the Indo-West Pacific, but has one lineage present in the north Atlantic Ocean. Polyphyly across ocean realms prevails in the specious and globally distributed genus Scaphander with multiple speciation events between Indo-Pacific and Atlantic lineages but also with several episodes of cladogenesis within realms. Two rare cases of species with a broad distribution spanning the Indo-West Pacific and Atlantic realms are confirmed (S. meridionalis and S. nobilis)

Résumé [+] [-]This study investigated the taxonomy and distribution of the deep-sea polyplacophoran mollusc Nierstraszella Sirenko, 1992 in the Indo-West Pacific, based on a collection of 516 specimens collected in the Philippines and Solomon Islands. Although seven species names have historically been proposed in this group of chitons, all have been considered as synonyms of the monotypic N. lineata (Nierstrasz, 1905). Morphological examination of this new material reveals the presence of two species. N. lineata is distinct from N. andamanica (Smith, 1906), based on morphological characters given in the original species description and very distinctly different morphology of aesthete pores in the shell surface. Furthermore, populations of N. andamanica in the Philippines and Solomon Islands are locally colonized with the epibiotic (ectoparasitic) bryozoan Pseudobathyalozoon profundum d'Hondt, 2006. These bryozoans attach ventrally to the girdle of the host chiton and the erect zooids feed within the pallial cavity, among the chiton's gills.

Résumé [+] [-]Lepidopleurida is the earliest diverged group of living polyplacophoran molluscs. They are found predominantly in the deep sea, including sunken wood, cold seeps, other abyssal habitats, and a few species are found in shallow water. The group is morphologically identified by anatomical features of their gills, sensory aesthetes, and gametes. Their shell features closely resemble the oldest fossils that can be identified as modern polyplacophorans. We present the first molecular phylogenetic study of this group, and also the first combined phylogenetic analysis for any chiton, including three gene regions and 69 morphological characters. The results show that Lepidopleurida is unambiguously monophyletic, and the nine genera fall into five distinct clades, which partly support the current view of polyplacophoran taxonomy. The genus Hanleyella Sirenko, 1973 is included in the family Protochitonidae, and Ferreiraellidae constitutes another distinct clade. The large cosmopolitan genus Leptochiton Gray, 1847 is not monophyletic; Leptochiton and Leptochitonidae sensu stricto are restricted to North Atlantic and Mediterranean taxa. Leptochitonidae s. str. is sister to Protochitonidae. The results also suggest two separate clades independently inhabiting sunken wood substrates in the south-west Pacific. Antarctic and other chemosynthetic-dwelling species may be derived from wood-living species. Substantial taxonomic revision remains to be done to resolve lepidopleuran classification, but the phylogeny presented here is a dramatic step forward in clarifying the relationships within this interesting group.

Résumé [+] [-]Introduction: Chitons (Polyplacophora) are molluscs considered to have a simple nervous system without cephalisation. The position of the class within Mollusca is the topic of extensive debate and neuroanatomical characters can provide new sources of phylogenetic data as well as insights into the fundamental biology of the organisms. We report a new discrete anterior sensory structure in chitons, occurring throughout Lepidopleurida, the order of living chitons that retains plesiomorphic characteristics. Results: The novel “Schwabe organ” is clearly visible on living animals as a pair of streaks of brown or purplish pigment on the roof of the pallial cavity, lateral to or partly covered by the mouth lappets. We describe the histology and ultrastructure of the anterior nervous system, including the Schwabe organ, in two lepidopleuran chitons using light and electron microscopy. The oesophageal nerve ring is greatly enlarged and displays ganglionic structure, with the neuropil surrounded by neural somata. The Schwabe organ is innervated by the lateral nerve cord, and dense bundles of nerve fibres running through the Schwabe organ epithelium are frequently surrounded by the pigment granules which characterise the organ. Basal cells projecting to the epithelial surface and cells bearing a large number of ciliary structures may be indicative of sensory function. The Schwabe organ is present in all genera within Lepidopleurida (and absent throughout Chitonida) and represents a novel anatomical synapomorphy of the clade. Conclusions: The Schwabe organ is a pigmented sensory organ, found on the ventral surface of deep-sea and shallow water chitons; although its anatomy is well understood, its function remains unknown. The anterior commissure of the chiton oesophagial nerve ring can be considered a brain. Our thorough review of the chiton central nervous system, and particularly the sensory organs of the pallial cavity, provides a context to interpret neuroanatomical homology and assess this new sense organ.

Résumé [+] [-]Recently we described several new species of chitons living in deep water deposits of sunken wood in the southwest Pacific (Sigwart & Sirenko 2012). Among these, one species, Leptochiton clarki Sigwart & Sirenko, 2012, is homonymous with a fossil taxon of the same genus: Leptochiton clarki Berry, 1922. Herein, we replace this homonym with a new name according to International Code of Zoological Nomenclature (ICZN 1999: Art. 57.2).

Résumé [+] [-]There are 23 species of chitons that live and feed on sunken land plant remains. They belong to three genera Ferreiraella, Leptochiton, and Nierstraszella. In the Carboniferous chitons changed their common food on a cellulose several times independently. Most of the species that live on sunken land plants are distributed along the tropical west and east coasts of the Pacific Ocean and in the Caribbean Sea, which was one of the portions of Pantalassa in the past geological ages. All these species of chitons belong to families that have mostly deep water members with generally plesiomorphic morphology. One can assume that the deep waters off southern Japan, Philippines, Indonesia, New Caledonia, Vanuatu, New Zealand from the western part of Pacific, and off Baja California and the Panama Basin from the eastern Pacific, as well as the Caribbean Sea are all regions where species with primitive character states have accumulated and persisted over geological time. In the future, one would expect a number of other “living fossil” species to be found in these deep water areas of Pantalassa remaining to the present time.

Résumé [+] [-]Two new species of the genus Leptochiton are described: L. madagascaricus sp. n. from north Madagascar, depths 362 to 431 m, and L. blikshteini sp. n. from southern Mozambique Channel, depths 148 to 152 m. They are characterized by the relatively thick valves, the anteriorly located mucro and the longitudinal rows of granules in the central areas of the intermediate valves. Leptochiton madagascaricus sp. n. differs from similar species by having trapezoidal valves, closely set granules in the pleural areas of the intermediate valves, broad, dorsally bent scales with a wide bulbous base, and slender, numerous teeth of the radula. Leptochiton blikshteini sp. n. differs from other similar species from the southwestern Indian Ocean by having granules arranged staggered-order in the lateral and postmucronal areas and in elongate, flattened, sharply pointed dorsal spicules with 1–2 ribs.

Résumé [+] [-]The paper describes a new species of the genus Thermochiton, T. papuaensis sp. nov., found in deep waters off Papua New Guinea. This species differs from T. undocostatus primarily in the dorsal scales, the marginal spicules, sculpture of the jugal area and the shape of the central teeth of radula. There are apparent similarities between the species of the genus Thermochiton, Connexochiton platynomenus, C. kaasi and Ischnochiton crassus. The last species is proposed to be transferred to Connexochiton. Owing to the friable, rusty brown deposits that densely cover the shell and girdle of both specimens of T. papuaensis, the latter probably lives in areas of high chemical activity.

Résumé [+] [-]A new genus and new species of the family Callistoplacidae from the bathyal zone near Guadeloupe Island in the Caribbean Sea are described. Caribbochiton guadeloupensis n. gen. et n. sp. is unlike other genera in the family Callistoplacidae: it has no ribs on end valves or on lateral areas of intermediate valves. According to other morphological features (thick shell, relatively narrow valves, noticeably raised lateral areas, similar slit formula, insertion plate teeth thickened at edges of slits, dorsal scales), this genus is closest to the family Callistoplacidae. Given that a number of species of the family do not have at a young age the ribs which appear later, we hypothesise that the new genus could have evolved as a result of paedomorphosis. An emended diagnosis of the family Callistoplacidae is hereby proposed.

Résumé [+] [-]Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates.

Sirenko B.I. 1997. Position in the system and the origin of deep-water chitons of the family Ferreiraellidae (Mollusca: Polyplacophora). Ruthenica 7(2): 77-89
Résumé [+] [-]The study of paratype of Xylochiton xylophagus Gowlett-Holmes et Jones, 1992 and a comparison with species of the genus Ferreiraella prove that this species belongs to the latter genus. The position of the family Ferreiraellidae Dell' Angelo et Palazzi, 1991 in the system of Polyplacophora and the validity of this name are discussed. It is proposed to regard names Abyssochitonidae Dell' Angelo et Palazzi, 1989 and Xylochitonidae Gowlett-Holmes et Jones, 1992 as junior synonyms of Ferreiraellidae, because the name Abyssochifon Dell' Angelo et Palazzi, 1989 is a junior synonym of Ferreiraella Sirenko, 1988 (based on the same species) , and the invalidity of the name Abyssochifon was recognized by its authors in the same publication. A revised diagnosis of the fami ly Ferreiraellidae is given. Based on comparison of morphological and ecological features, a supposition is made about close relationship between Fereiraellaand Glaphurochifon, species of which in the Upper Carboniferous inhabited shallow waters of south-eastern part of present North America . Probably the genus Ferreiraella originated from one of representatives of the genus Graphurochiton that in the Upper Carboniferous apparently inhabited sunken plant remains and fed on them, since plates of its shell were found in dark grey shales. The first Ferreiraella species that originated in the Upper Carboniferous was possibly F. caribbensis, now living in the Caribbean Sea or species closely related to it. Later the representatives of Ferreiraella spread with waters of the Paleotethys westwards to the region of present California and Panama Bay and eastwards to the region of present Japan, Indonesia and New Zealand. The supercontinent Pangea that was formed in the Permian divided the common distribution range of the genus Ferreiraella into two parts. In the Jurassic, the Pangea began to split into blocks, and marine organisms inhabiting shelf and slope of these blocks moved with them. Since then chitons Ferreiraella remained in the region of the former supercontinent Pangea only in those areas where sunken wood was accumulated.

Résumé [+] [-]Chitons of the order Lepidopleurida are a regular, and sometimes abundant, component of deep-sea faunas associated with sunken wood and other plant debris. Eleven species are known from off New Caledonia (6 species) and Vanuatu (10 species), at depths between 110 and 2340 m. These show discrete bathymetric segregation, but up to three species of Leptochiton may cooccur in the same haul. Five new species and one subspecies are described: Leptochiton boucheti sp. nov., L. deforgesi sp. nov., L. vanbellei sp. nov., L. saitoi sp. nov., L. thandari sp. nov., and Ferreiraella xylophaga karenaessp. Novo Beside sunken plant remains, species of Leptochitonidae are known from reduced environments, both in shallow and deep water, and it is open to speculation whether sunken wood represent the ancestral habitat from which the family radiated, or whether sunken wood represents a secondary habitat that was invaded sometime during the Mesozoic.

Mémoires du Muséum national d'Histoire naturelle 196:41-75, ISBN:978-2-85653-614-8
Résumé [+] [-]Study of deep-water chitons from around New Caledonia and Vanuatu has revealed 35 species, of which 25 species were identified to species and 10 only to genus. This article includes 7 new records for this area of which 4 are described as new species: Ischnochiton crassus Kaas, 1985, Stenosemus robustus Kaas, 1991, S. herosae n. sp., Connexochiton discernibilis Kaas, 1991, Loricella vanbellei n. sp., L. eernissei n. sp. and L. dellangeloi n. sp. In addition, Vermichiton vermiculus Kaas, 1991 is reviewed. Based on available biogeographic data it is proposed that Loricella originated off South Australia during the Oligocene, in a time of global cooling. Later, Loricella extended its range north up to Taiwan and east to Tonga, most likely remaining in the bathyal zone. These new discoveries add to the already high diversity and high proportion of endemics known from this region, and a speculative interpretation of these patterns is offered in conclusion.

Molecular phylogeny of the Pectinoidea (Bivalvia) indicates Propeamussiidae to be a non-monophyletic family with one clade sister to the scallops (Pectinidae). Molecular Phylogenetics and Evolution 137: 293-299. DOI:10.1016/j.ympev.2019.05.006
Résumé [+] [-]Scallops (Pectinidae) are one of the most diverse families of bivalves and have been a model system in evolutionary biology. However, in order to understand phenotypic evolution, the Pectinidae needs to be placed in a deeper phylogenetic framework within the superfamily Pectinoidea. We reconstructed a molecular phylogeny for 60 species from four of the five extant families within the Pectinoidea using a five gene dataset (12S, 16S, 18S, 28S rRNAs and histone H3). Our analyses give consistent support for the non-monophyly of the Propeamussiidae, with a subset of species as the sister group to the Pectinidae, the Propeamussiidae type species as sister to the Spondylidae, and the majority of propeamussiid taxa sister to the Spondylidae + Pr. dalli. This topology represents a previously undescribed relationship of pectinoidean families. Our results suggest a single origin for eyes within the superfamily and likely multiple instances of loss for these characters. However, it is now evident that reconstructing the evolutionary relationships of Pectinoidea will require a more comprehensive taxonomic sampling of the Propeamussiidae sensu lato.

Résumé [+] [-]The neogastropod fasciolariid genus Fusolatirus Kuroda & Habe, 1971, is redescribed based on shell and radula characters Fourteen species are tentatively placed in the genus, nine of them for the first time, all front moderately deep water (50-300 meters) in the tropical Indo-West Pacific. Additional species currently placed in Latirus or Peristernia may also be referable to Fusolatirus when the range of shell and radula characters are better understood. However, Eve do not regard as congeneric Fusolatirus kurodai (Okutani & Sakurai, 1964) nor Fusolatirus kuroseanus Okutani, 1975. Fusolatirus luteus n. sp. and Fusolatirus pachyus n. sp., both from the New Caledonia area, are described. Latirus cloveri Snyder, 2003 [June] is a new synonym of Euthria suduirauti Fraussen, 2003 [April], originally described as a buccinid and here referred to Fusolatirus. The ranges of Fusolatirus balicasagensis (Bozzetti, 1997), F kandai (Kuroda, 1950), and F. rikae (Fraussen, 2003), earlier known only from Japan and/or the Philippines, are extended to the South Pacific.

Résumé [+] [-]Species identities of Goniobranchus nudibranchs with white bodies and various marginal bands have long been problematic. In this study, specimens of these Goniobranchus nudibranchs from the Philippines, Peninsular Malaysia, Japan, Papua New Guinea, and Madagascar were analyzed and molecular data were obtained in order to re-examine the relationships between species within this “white Goniobranchus with marginal bands” group. The analyses clearly recovered six species groups corresponding to the described species Goniobranchus albonares, G. preciosus, G. rubrocornutus, G. sinensis, and G. verrieri as well as one new species, G. fabulus Soong & Gosliner, sp. nov. Notably, G. preciosus, G. sinensis, G. rubrocornutus, G. verrieri, and G. fabulus Soong & Gosliner, sp. nov. exhibit color variation and polymorphism, suggesting that some aspects of color patterns (e.g., presence or absence of dorsal spots) may not always be useful in the identification of species in the “white Goniobranchus with marginal bands” group, whereas other features such as gill and rhinophore colors and the arrangement and colors of the mantle marginal bands are more diagnostic for each species.

Résumé [+] [-]Cerithium koperbergi is a rare gastropod of the family Cerithiidae from the tropical Indo-West Pacific. The species has a small, unusual shell and often inhabits deeper water, fore-reef habitats that are atypical for the genus. Anatomical investigations reveal that it possesses a combination of features heretofore considered diagnostic of two main cerithiid subfamilies: Cerithiinae and Bittiinae. While the shell is bittiine, the animal lacks mesopodial pedal glands and possesses a seminal receptacle (vs. a spermatophore bursa) in the lateral lamina of the oviduct, which are considered to be cerithiine features. Re-evaluation of the anatomy of Bittium reticulatum, the type species of Bittium, indicates the defining anatomical difference in oviduct anatomy between the two subfamilies does not stand up to closer scrutiny. Partial mitochondrial cytochrome c oxidase I (COI) sequences support the interpretation that C. koperbergi is a species complex around the western Pacific rim comprising three divergent mitochondrial lineages. Bayesian analysis of partial mitochondrial COI and 16S rRNA sequences confirm the placement of the C. koperbergi complex within a monophyletic Bittiinae, despite the apparent absence of a unifying anatomical feature. Species in the C. koperbergi complex are here united in Pictorium nov. gen. and two species are described as new. It is hypothesized that features of the midgut may be diagnostic of the Bittiinae, but more comparative data are needed.

Résumé [+] [-]The genus Clea from SE Asia is from one of only two unrelated families among the megadiverse predatory marine Neogastropoda to have successfully conquered continental waters. While little is known about their anatomy, life history and ecology, interest has grown exponentially in recent years owing to their increasing popularity as aquarium pets. However, the systematic affinities of the genus and the validity of the included species have not been robustly explored. Differences in shell, operculum and radula characters support separation of Clea as presently defined into two distinct genera: Clea, for the type species Clea nigricans and its allies, and Anentome for Clea helena and allies. A five-gene mitochondrial (COI, 16S, 12S) and nuclear (H3, 28S) gene dataset confirms the placement of Anentome as a somewhat isolated offshoot of the family Nassariidae and sister to the estuarine Nassodonta. Anatomical data corroborate this grouping and, in conjunction with their phylogenetic placement, support their recognition as a new subfamily, the Anentominae. The assassin snail Anentome helena, a popular import through the aquarium trade so named for their voracious appetite for other snails, is found to comprise a complex of at least four species. None of these likely represents true Anentome helena described from Java, including a specimen purchased through the aquarium trade under this name in the US and one that was recently found introduced in Singapore, both of which were supported as conspecific with a species from Thailand. The introduction of Anentome “helena” through the aquarium trade constitutes a significant threat to native aquatic snail faunas which are often already highly imperiled. Comprehensive systematic revision of this previously unrecognized species complex is urgently needed to facilitate communication and manage this emerging threat.

Résumé [+] [-]A new genus, Limatium gen. n., and two new species, L. pagodula sp. n. and L. aureum sp. n. are described, found on outer slopes of barrier reefs and fringing reefs in the South Pacific. They are rare for cerithiids, which typically occur in large populations. The two new species are represented by 108 specimens sampled over a period of 30 years, only 16 of which were collected alive. Three subadults from the Philippines and Vanuatu likely represent a third species. In addition to their rarity, Limatium species are atypical for cerithiids in their smooth, polished, honey to golden brown shells with distinctive white fascioles extending suture to suture. The radula presents a unique morphology that does not readily suggest an affinity to any of the cerithiid subfamilies. Two live-collected specimens, one of each species and designated as holotypes, were preserved in 95% ethanol and sequenced. Bayesian analysis of partial COI and 16S rDNA sequences demonstrates a placement in the Bittiinae, further extending our morphological concept of the subfamily.

Frogs and tuns and tritons – A molecular phylogeny and revised family classification of the predatory gastropod superfamily Tonnoidea (Caenogastropoda). Molecular Phylogenetics and Evolution 130: 18-34. DOI:10.1016/j.ympev.2018.09.016
Résumé [+] [-]The Tonnoidea is a moderately diverse group of large, predatory gastropods with ∼360 valid species. Known for their ability to secrete sulfuric acid, they use it to prey on a diversity of invertebrates, primarily echinoderms. Tonnoideans currently are classified in seven accepted families: the comparatively well known, shallow water Bursidae, Cassidae, Personidae, Ranellidae, and Tonnidae, and the lesser-known, deep water Laubierinidae and Pisanianuridae. We assembled a mitochondrial and nuclear gene (COI, 16S, 12S, 28S) dataset for ∼80 species and 38 genera currently recognized as valid. Bayesian analysis of the concatenated dataset recovered a monophyletic Tonnoidea, with Ficus as its sister group. Unexpectedly, Thalassocyon, currently classified in the Ficidae, was nested within the ingroup as the sister group to Distorsionella. Among currently recognized families, Tonnidae, Cassidae, Bursidae and Personidae were supported as monophyletic but the Ranellidae and Ranellinae were not, with Cymatiinae, Ranella and Charonia supported as three unrelated clades. The Laubierinidae and Pisanianuridae together form a monophyletic group. Although not all currently accepted genera have been included in the analysis, the new phylogeny is sufficiently robust and stable to the inclusion/exclusion of nonconserved regions to establish a revised family-level classification with nine families: Bursidae, Cassidae, Charoniidae, Cymatiidae, Laubierinidae, Personidae, Ranellidae, Thalassocyonidae and Tonnidae. The results reveal that many genera as presently circumscribed are para- or polyphyletic and, in some cases support the rescue of several genus-group names from synonymy (Austrosassia, Austrotriton, Laminilabrum, Lampadopsis, Personella, Proxicharonia, Tritonoranella) or conversely, support their synonymization (Biplex with Gyrineum). Several species complexes are also revealed that merit further investigation (e.g., Personidae: Distorsio decipiens, D. reticularis; Bursidae: Bursa tuberosissima; Cassidae: Echinophoria wyvillei, Galeodea bituminata, and Semicassis bisulcata). Consequently, despite their teleplanic larvae, the apparently circumglobal distribution of some tonnoidean species is the result of excessive synonymy. The superfamily is estimated to have diverged during the early Jurassic (∼186 Ma), with most families originating during a narrow ∼20 My window in Albian-Aptian times as part of the Mesozoic Marine Revolution.

Résumé [+] [-]Eye reduction occurs in many troglobitic, fossorial, and deep-sea animals but there is no clear consensus on its evolutionary mechanism. Given the highly conserved and pleiotropic nature of many genes instrumental to eye development, degeneration might be expected to follow consistent evolutionary trajectories in closely related animals. We tested this in a comparative study of ocular anatomy in solariellid snails from deep and shallow marine habitats using morphological, histological, and tomographic techniques, contextualized phylogenetically. Of 67 species studied, 15 lack retinal pigmentation and at least seven have eyes enveloped by surrounding epithelium. Independent instances of reduction follow numerous different morphological trajectories. We estimate eye loss has evolved at least seven times within Solariellidae, in at least three different ways: characters such as pigmentation loss, obstruction of eye aperture, and “lens” degeneration can occur in any order. In one instance, two morphologically distinct reduction pathways appear within a single genus, Bathymophila. Even amongst closely related animals living at similar depths and presumably with similar selective pressures, the processes leading to eye loss have more evolutionary plasticity than previously realized. Although there is selective pressure driving eye reduction, it is clearly not morphologically or developmentally constrained as has been suggested by previous studies.

Résumé [+] [-]The genus Gemmulobonorua Shuto, 1989, until now known only from Upper Miocene-Lower Pleistocene deposits of the Tethys, is recorded in Recent faunas, with five new bathyal species from New Caledonia, Indonesia, Mozambique Channel, and the Philippines. Radular morphology indicates that Cemmuloborsoma belongs to the subfamily Turnnae, and not to Borsoruinae, where it had been allocated based on shell morphology. Columellar pleats, which have long been considered a synapomorphy of the borsoruid group of genera, have thus been acquired independently in the Turnnae. The consequence of this finding is that the current (sub)familly allocation of some genera, based on shell characters only, may need reevaluation.

Résumé [+] [-]Nineteen new species are described from the bathyal zone of the Arafura Sea at depths between 146 and 1084 m. The genus Lusitanops is recorded for the first time from the Indo-Pacific and Clinura vitrea sp. nov. is the first Recent representative of this hitherto Cenozoic fossil genus. Based on shell and radula morphology, the classification of Heteroturris in the Clathurellinae is confirmed. Including new species described here, there are now 92 turrid species recorded from Indonesia at depths greater than 200 m.

Sysoev A. 2002. On the type species of Iotyrris Medinskaya et Sysoev, 2001 (Gastropoda, Turridae). Ruthenica 12(2): 169-171
Résumé [+] [-]The monotypical genus Iotyrris was recently described [Medinskaya, Sysoev, 2001] for Xenuroturris cerithiformis Powell, 1967. The main distinguishing character of the genus is the structure of its radular teeth, which are semi-enrolled but not wishbone-type as in species of Xenuroturris. The material for the study of anatomy and radula of X. cerithiformis came from the Marquesas Islands, whereas the species has been originally described from the Hawaii and was considered an endemic of these islands. Later, R.N. Kilburn [pers. Comm.] expressed a doubt on the correctness of identification of the species, and this became a reason of an additional study. Reexamination of the material from the Marquesas stored in the Museum national d' Histoire naturelle, Paris (MNHN), and study of the radula of a paratype of X. cerithiformis revealed that the latter species possesses a different radula and thus cannot be included in Iotyrris. This, together with revealed conchological differences, requires a description of a new species for the material from the Marquesas. Since misidentified X. cerithiformis was designated as the type species of Iotyrris, provisions of the Article 70.3 of the ICZN must be applied . Therefore, the type species of /otyrris Medinskaya et Sysoev, 200 I is here fixed as Iotyrris marquesensis Sysoev, 2002, misidentified as Xenuroturris cerithiformis Powell, 1967 in the original designation of Medinskaya and Sysoev [2001].

Résumé [+] [-]Several hundred species of turriform gastropods (Drilliidae, Turridae, Conidae) have been collected at bathyal depths in New Caledonia and other South-West Pacific archipelagoes. Seventeen new species are here described in the genera Drillia (Drilliidae), Inquisitor, Funa, Zemacies, Comitas (Turridae), Benthofascis, Bathytomq Glyphostoma, Daphnella, Spergo, Gymnobela, Teretiopsis, and Rocroithys gen. Novo (Conidae). The genus Zemacies, until now known from Paleocene to Pliocene deposits in New Zealand and Australia, is recognized for the first time in the Recent fauna, and includes Z. excelsa sp. Novo from New Caledonia, and Z. queenslandica (Powell, 1969) comb. nov., from Queensland to Papua. Benthofascis lozoueti sp. Nov., from the Norfolk Ridge, is the second confirmed species of the genus. Bathytoma boholica Parth, 1994 is synonymized with B. atractoides (Watson, 1881), and the validity of B. hedlandensis Tippett & Kosuge, 1994 is questioned. The range of Spergo fusiformis (Kuroda & Habe, 1961), hitherto known only from Japan, is shown to extend to Madagascar and the South-West Pacific. Daphnella itonis, which has been known under that name in the Japanese literature for more than 40 years, is formally described for the first time, based on specimens from New Caledonia. The species has very long radular teeth and, like molluscivorous species of cones, appears to be feeding on gastropods.

Résumé [+] [-]The gastropod family Eulimidae has attracted considerable attention as one of the most diverse groups of parasitic molluscs in terms of number of species and ranges of body plans and parasitic strategies. However, the phylogenetic position of the family has not been established within the Hypsogastropoda and this has hampered the inference of ancestral states in the evolution of the morphology and parasitic strategies. Here we present Bayesian and maximum likelihood phylograms of Hypsogastropoda based on nuclear and mitochondrial loci (18S and 28S rRNA, Histone H3, COI and 16S rRNA) and a better taxonomic sampling than in previous molecular analyses, to determine the position of Eulimidae. The resulting trees suggest Vanikoridae as the sister group of Eulimidae; the two families are collectively placed in the newly redefined superfamily Vanikoroidea, with Truncatelloidea and (potentially paraphyletic) Rissooidea as closest relatives. Vanikorids are protandrous hermaphrodites as are many eulimids and are essentially carnivorous, differing from the mostly gonochoristic and herbivorous/detritivorous Truncatelloidea and Rissooidea. The mode of feeding may have a phylogenetic signal also within Eulimidae, where radula-less species constitute a robust clade. Other new findings include a close affinity of the submarine-cave Pickworthiidae to Cerithioidea and a terminal position of Nystiellidae within the paraphyletic Epitoniidae.

Résumé [+] [-]Rare species of three long-lived lucinid genera, Gibbolucina Cossmann, 1904, Barbierella Chavan, 1938 and Retrolucina n. gen., with origins in the Paleocene and Eocene of western Tethys, are present in the Mozambique Channel area of the southwestern Indian Ocean but absent elsewhere in the Indo-West Pacific. A new species, Gibbolucina zelee n. sp., is described from the Banc de la Zélée and western Madagascar that resembles Miocene species from western France. Since their origin in the Paleocene to the present day Barbierella species have always been rare. New records and images, including syntypes, are provided for Barbierella louisensis (Viader, 1951) from Mauritius and the Mozambique Channel, with Barbierella scitula Oliver & Abou-Zeid, 1986 from the Red Sea regarded as synonym. A new genus, Retrolucina n. gen., is proposed with the living Lucina voorhoevei D eshayes, 1857 (usually called Eomiltha voorhoevei) as type species and also including Lucina defrancei Deshayes, 1857, a strikingly similar species from the Eocene of the Paris Basin. Retrolucina n. gen. differs from Eomiltha Cossmann, 1912 in shape, sculpture and hinge characters. Monitilora Iredale, 1930, another genus of Paleocene or earlier origins, includes a few living species in the Indo-West Pacific and is now identified from Mozambique with Monitilora sepes (Barnard, 1964) (formerly Phacoides sepes Barnard, 1964). It is suggested that Gibbolucina, Barbierella and Retrolucina n. gen. species became isolated in the western Indian Ocean following the closure of the Tethyan Seaway in the early Miocene while their congeners in western Tethys became extinct. The survival of these rare genera, with restricted geographical ranges and seemingly small populations, runs counter to current ideas concerning long-term extinction risk.

Résumé [+] [-]Marine bivalves of the family Lucinidae possess a likely obligate chemosymbiosis with sulphide-oxidising bacteria from which they derive much of their nutrition. Molecular analysis has shown that species of the 'Anodontia' group form a distinct clade within the monophyletic Lucinidae. Species identification of the largely tropical 'Anodontia' group, has been confused because of the white, sub-spherical, smooth, toothless shells, with the name Anodontia edentula used uncritically for most Indo-West Pacific species. Preliminary morphological analysis also showed that the group was much more diverse than previously realised. The present systematic revision of the world Anodontia species, based on museum collections, field sampling, anatomical and molecular data, now recognises 25 species (eight of these new). These species are divided into eight subgenera (four of these, Euanodontia, Afrophysema, Crytophysema and Bythosphaera are new) on the basis of shell morphology, corroborated by some molecular data. Two species are known from the tropical eastern Pacific, two from the Western Atlantic, five from the eastern Atlantic and 16 from the Indo-West Pacific. Two new genera, Neophysema (type species N. aphanes sp. nov.) and Leucosphaera (type species Loripinus salamensis Thiele & Jaeckel, 1931), are proposed for species previously confused with Anodontia.

Résumé [+] [-]Although species of the chemosymbiotic bivalve family Lucinidae are often diverse and abundant in shallow water habitats such as seagrass beds, new discoveries show that the family is equally speciose at slope and bathyal depths, particularly in the tropics, with records down to 2500m. New molecular analyses including species from habitats down to 2000m indicate that these cluster in four of seven recognized subfamilies: Leucosphaerinae, Myrteinae, Codakiinae, and Lucininae, with none of these comprising exclusively deep-water species. Amongst the Leucosphaerinae, Alucinoma, Epidulcina, Dulcina, and Myrtina live mainly at depths greater than 200m. Most Myrteinae inhabit water depths below 100m, including Myrtea, Notomyrtea, Gloverina, and Elliptiolucina species. In the Codakinae, only the Lucinoma clade live in deep water; Codakia and Ctena clades are largely restricted to shallow water. Lucininae are the most speciose of the subfamilies but only four species analyzed, Troendleina sp., Epicodakia' falkandica, Bathyaustriella thionipta, and Cardiolucina quadrata, occur at depths greater than 200m. Our results indicate that slope and bathyal lucinids have several and independent originations from different clades with a notable increased diversity in Leucosphaerinae and Myrteinae. Some of the deep-water lucinids (e.g. Elliptiolucina, Dulcina, and Gloverina) have morphologies not seen in shallow water species, strongly suggesting speciation and radiation in these environments. By contrast, C.quadrata clusters with a group of shallow water congenors. Although not well investigated, offshore lucinids are usually found at sites of organic enrichment, including sunken vegetation, oxygen minimum zones, hydrocarbon seeps, and sedimented hydrothermal vents. The association of lucinids with hydrocarbon seeps is better understood and has been traced in the fossil record to the late Jurassic with successions of genera recognized; Lucinoma species are particularly prominent from the Oligocene to present day.(c) 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 111, 401-420.

Résumé [+] [-]Intensive sampling of molluscs from the intertidal to depths of 800 m around the islands of Guadeloupe in the Lesser Antilles (KARUBENTHOS 2012, 2015) recovered 25 species of Lucinidae. All the Guadeloupe species are described and illustrated including details of larval shells and the taxonomy revised within the context of the wider western Atlantic fauna and recent classifications. Concurrent molecular analysis has helped separate frequently confounded species. ‘Myrtea’ pristiphora is placed in the Leucosphaerine genus Myrtina previously known from the Indo-West Pacific. A second western Atlantic species of Callucina, C. pauperatus previously known from the Pliocene of Jamaica is recognised from the southern Caribbean and off Brazil. The deeper water species ‘Myrteopis’ lens is placed in Afrolucina previously known from the eastern Atlantic. Lucinids commonly identified as Ctena orbiculata are shown to belong to two distinct species, C. orbiculata in the Gulf of Mexico and Florida and C. imbricatula in the Caribbean. Epicodakia is recognised for the first time in the western Atlantic with E. pectinata widely distributed across the region and E. filiata recorded from deeper water. Three species of Lucina are recognised, Lucina pensylvanica in the Gulf of Mexico and Florida and the similar Lucina roquesana from the Caribbean and Bahamas while the smaller L. aurantia has a wide distribution from central America to the Bahamas. A new species of Parvilucina, P. latens is described; this is similar to P. pectinella but has an internal ligament. The long problematic species ‘Codakia’ cubana is assigned to Ferrocina. A new genus, Guyanella is introduced for Parvilucina clenchi the smallest known lucinid. A critical reassessment of the lucinid fauna of the western Atlantic Ocean identifies 46 species for the region with 33 of these living at depths less than 200 m. Deeper-water habitats have been much less investigated except at sites of hydrocarbon seeps. Some species are widespread throught the whole region but others have more restricted ranges. Notable are species pairs, for example of Ctena, Lucina, Lucinisca and Parvilucina that are either largely Caribbean or Gulf of Mexico/Floridian in distribution. Although extralimital, two problematic species from the mid-south Atlantic island of St Helena are refigured and placed in Cavilinga.

Résumé [+] [-]A new molecular phylogeny of the Lucinidae using 18S and 28S rRNA and cytochrome b genes includes many species from the tropical Western Atlantic as well as additional taxa from the Indo-West Pacific. This study provides a phylogenetic framework for a new taxonomy of tropical Western Atlantic lucinids. The analysis confirmed five major clades—Pegophyseminae, Leucosphaerinae, Myrteinae, Codakiinae and Lucininae, with Monitilorinae and Fimbriinae represented by single species. The Leucosphaerinae are expanded and include Callucina winckworthi and the W. Atlantic Myrtina pristiphora that groups with several Indo-West Pacific Myrtina species. Within the Codakiinae two abundant species of Ctena from the Western Atlantic with similar shells are discriminated as C. orbiculata and C. imbricatula, while in the Indo-West Pacific Ctena bella is a probable species complex. The Lucininae is the most species rich and disparate subfamily with several subclades apparent. Three species of Lucina are recognized in the W. Atlantic L. aurantia, L. pensylvanica and L. roquesana. Pleurolucina groups near to Cavilinga and Lucina, while Lucinisca muricata is more closely related to the E. Pacific L. fenestrata than to the Atlantic L. nassula. A new species of Parvilucina is identified from molecular analyses having been confounded with Parvilucina pectinata but differs in ligament structure. Also, the former Parvilucina clenchi is more distant and assigned to Guyanella.

Résumé [+] [-]Species identified as Pillucina are paraphyletic in molecular analyses and a new generic name, Rugalucina, is introduced for a complex of three similar species Rugalucina angela from the northern Indian Ocean and Red Sea, R. vietnamica from South East Asia, and R. munda from northern and north eastern Australia. Lucina concinna from the Red Sea, previously synonymised with P. vietnamica/angela is recognised as a Rugalucina-like species but with a very short anterior adductor scar. Divaricella cypselis from Karachi is similarly now recognised as a distinct species, probably related to Rugalucina but with oblique commarginal sculpture and a short adductor scar. A group of minute Indo-West Pacific lucinids with highly unusual multi-cuspate lateral teeth and previously classified as Pillucina are separated under a new genus Pusillolucina gen. nov., with the description of three new species P. arabica, P. africana, and P. biritika from the Arabian Gulf, Mozambique, and Madagascar. Finally, a new genus, Notocina, is introduced for the small southern Atlantic species, Epicodakia falklandica, shown in molecular analyses to be misplaced at subfamily level and now classified in Lucininae and not Codakiinae with Epicodakia.

Résumé [+] [-]Profundiconus zardoyai sp. nov. is described from deep water material taken during several MNHN research cruises at Grand Passage, North New Caledonia. The new species is characterized by the very small shell length, conical to broadly conical shell shape with a moderate spire of sigmoid profile, and a white paucispiral protoconch. The pattern consists mainly of a variable number of narrow spiral bars of brown and white alternating dots and dashes on a purplish white to orange-brown ground color. The details of its radular morphology are reported. The new species has been molecularly characterised by sequencing a fragment of the COI gene. It is compared to Profundiconus kanakinus (Richard, 1983) and to Continuconus estivali (Moolenbeek & Richard in Röckel, Richard & Moolenbeek, 1995).

Résumé [+] [-]The genus Profundiconus Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in Profundiconus are discussed. In particular, we studied Profundiconus material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial cox1 gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of Profundiconus based on their shell and radular morphologies, and are introduced here as five new species: Profundiconus maribelae sp. nov. from the Solomon Islands; P. virginiae sp. nov. from Chesterfield Plateau (New Caledonia); P. barazeri sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); P. puillandrei sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and P. neocaledonicus sp. nov. from New Caledonia. Furthermore, Profundiconus teramachii forma neotorquatus (da Motta, 1984) is raised to specific status as P. neotorquatus (da Motta, 1984).

Résumé [+] [-]Although cone snails are among the most studied group of gastropods, new species are still regularly described. Here, we focus on Afonsoconus Tucker & Tenorio, 2013, a lineage that includes only two species from the Indo-Pacific Ocean. The analysis of molecular (partial mitochondrial cox1 gene sequences) and morphological (shell and radular tooth) characters revealed that the samples collected by dredging in deep water during a recent expedition carried out in the Mozambique Channel are different from the samples collected in the Pacific Ocean. We thus introduce here a new species, Afonsoconus crosnieri sp. nov., from the SW Indian Ocean including records from the Mozambique Channel, the Comoros and Glorieuses Islands, Madagascar, South Africa and Reunion Island.

Résumé [+] [-]Sixty-three Cardiidae species (including Tridacninae) sampled by the 2004 Panglao Marine Biodiversity Project (PMBP) to Panglao, Philippines, and the PANGLAO 2005 Deep-Sea Cruise are described. In addition, Cardiidae species lists of the Philippine Cuming Tour 2005 and AURORA 2007 expedition are provided. Four species are new to science: Fragum grasi spec. nov., Frigidocardium helios spec. nov., F. sancticaroli spec. nov. and Microcardium velatum spec. nov. For the following six species this paper includes the first published records for the Philippines: Acrosterigma dianthinum (Melvill & Standen, 1899), F. torresi (E.A. Smith, 1885), Fulvia (Laevifulvia) subquadrata Vidal & Kirkendale, 2007, Microfragum erugatum (Tate, 1889), M. subfestivum (Vidal & Kirkendale, 2007) and Vasticardium sewelli (Prashad, 1932). Indo-Pacific range extensions for several other species are given. Ecological data support assignment of Afrocardium to Orthocardiinae. Cardium (Ctenocardia) victor Angas, 1872 and Cardium bomasense Martin, 1917 are transferred to Freneixicardia, the former being the sole extant representative of the genus, and of which Cardium (Trachycardium) hulshofi Pannekoek, 1936 is a new synonym. Based on shell morphology, it is shown that the current variously adopted generic assignments of Cardium lobulatum Deshayes, 1855, C. attenuatum G.B. Sowerby 2nd, 1841, C. biradiatum Bruguière, 1789 and C. multipunctatum G.B. Sowerby 1st in Broderip & Sowerby 2nd, 1833 are unsatisfactory. As a consequence, the alleged Indo-Pacific presence of the genus Laevicardium is questionable. Fulvia (Laevifulvia) imperfecta Vidal & Kirkendale, 2007 is a new synonym of “Laevicardium” lobulatum Deshayes, 1855. Habitat preferences of the taxa encountered during PMBP 2004 are defined, based on four main macro-habitat categories. SEM photos, showing the early ontogenetic stages, demonstrate markedly allomorphic growth of some taxa. Description of the process of development to the terminal shell shape provides a more complete species concept and rigorous species delimitation.

In this paper, five species are recognized, three of which are new to science: N. bechei from Taiwan, Philippines and Indonesia; N. probatum (Iredale, 1927) from northern Australia; N. australojaponicum spec. nov. From southern Japan and Korea; N. enigmaticum spec. nov. From the SouthWest Pacific and N. fulvum spec. nov. from Mozambique, Madagascar, Seychelles, India, Philippines and Vanuatu. All but the last species seem to occur perfectly parapatrically. With N. fulvum spec. nov., which is not confined to the Central Indo-Pacific but covers large parts of the Indian Ocean as well, the longitudinal range of Nemocardium is much wider than hitherto thought. A substitute lectotype is designated for Cardium bechei Reeve, 1847, and the New Zealand genus Varicardium Marwick, 1944, is synonymized with Nemocardium.

Terryn Y.. The Duplicaria duplicata (Linnaeus, 1758)-complex (Gastropoda: Terebridae): Part II. The ‘Duplicaria lamarckii-complex’ with the description of seven new species. : 16
Résumé [+] [-]After having established the identity of Duplicaria duplicata (Linnaeus, 1758) and its historical synonyms Duplicaria lamarckii (Kiener, 1839), Duplicaria duplicatoides (Bartsch, 1923) and Duplicaria reevei (Deshayes, 1857) and having highlighted the possible identity of Duplicaria morbida (Reeve, 1860) and Duplicaria nadinae (Aubry, 2008) (see Part I), a number of morpho-species, close in shell morphology to D. lamarckii, were studied. The present study reveals an additional 7 previously undescribed species with similarities to D. lamarckii, rediscovers the enigmatic species D. morbida in the Red Sea and tentatively includes D. nadinae within this informal morphological grouping, called the ‘lamarckii-complex’ of the Indian Ocean.

Résumé [+] [-]Bathymodiolinae are giant mussels that were discovered at hydrothermal vents and harboring chemosynthetic symbionts. Due to their close phylogenetic relationship with seep species and tiny mussels from organic substrates, it was hypothesized that they gradually evolved from shallow to deeper environments, and specialized in decaying organic remains, then in seeps, and finally colonized deep-sea vents. Here, we present a multigene phylogeny that reveals that most of the genera are polyphyletic and/or paraphyletic. The robustness of the phylogeny allows us to revise the genus-level classification. Organic remains are robustly supported as the ancestral habitat for Bathymodiolinae. However, rather than a single step toward colonization of vents and seeps, recurrent habitat shifts from organic substrates to vents and seeps occurred during evolution, and never the reverse. This new phylogenetic framework challenges the gradualist scenarios from shallow to deep. Mussels from organic remains tolerate a large range of ecological conditions and display a spectacular species diversity contrary to vent mussels, although such habitats are yet underexplored compared to vents and seeps. Overall, our data suggest that for deep-sea mussels, the high specialization to vent habitats provides ecological success in this harsh habitat but also brings the lineage to a kind of evolutionary dead end.

Résumé [+] [-]Cephalopod shells can be affected by postmortem transport and biostratigraphic condensation, but direct estimates of the temporal and spatial resolutions of cephalopod assemblages are missing. Amino acid racemisation calibrated by 14C demonstrates a centennial-scale time averaging (<500 years) of Nautilus macromphalus in sediment-starved, epi- and mesobathyal pelagic environments. The few shells that are thousands of years old are highly degraded. The median occurrence of dead shells is at 445 m depth, close to the 300–400 m depth where living N. macromphalus are most abundant. Therefore, dead shells of this species accumulate at a centennial temporal resolution and with excellent bathymetric fidelity. Dead Nautilus shells exist for only a few hundred years on the seafloor, in contrast to the biostratigraphically condensed mixture of extant foraminifers and foraminifers that went extinct during the Pleistocene. Cephalopod shells that do not show any signs of early diagenetic cementation are unlikely to be biostratigraphically condensed.

Tëmkin I. 2006. Morphological perspective on the classification and evolution of Recent Pterioidea (Mollusca: Bivalvia). Zoological Journal of the Linnean Society 148: 253-312
Résumé [+] [-]The evolutionary relationships of the Recent Pterioidea are inferred from a phylogenetic analysis of representatives of all pterioidean genera based on original observations of anatomy and shell morphology, and an extensive survey of bivalve literature. The well-resolved cladogram supports monophyly for the superfamily, but renders all but one family (the monotypic Pulvinitidae) polyphyletic. In addition, these results reveal a considerable level of convergence and parallelisms through the Pterioidea. The branching order of pterioid genera in the morphological analysis is largely corroborated by the sequence of their appearance in the fossil record. The palaeontological evidence provides important information on dating lineage splitting events and transitional taxa. The proposed phylogeny integrates the cladistic analysis of the Recent Pterioidea with the fossil record and suggests that the crown-group pterioideans probably originated in the Triassic from the Bakevelliidae, an extinct paraphyletic stem group from which the Ostreoidea are also ultimately derived.

Tëmkin I. 2010. Molecular phylogeny of pearl oysters and their relatives (Mollusca, Bivalvia, Pterioidea). BMC evolutionary biology 10(342): 1-28
Résumé [+] [-]Background: The superfamily Pterioidea is a morphologically and ecologically diverse lineage of epifaunal marine bivalves distributed throughout the tropical and subtropical continental shelf regions. This group includes commercially important pearl culture species and model organisms used for medical studies of biomineralization. Recent morphological treatment of selected pterioideans and molecular phylogenetic analyses of higher-level relationships in Bivalvia have challenged the traditional view that pterioidean families are monophyletic. This issue is examined here in light of molecular data sets composed of DNA sequences for nuclear and mitochondrial loci, and a published character data set of anatomical and shell morphological characters. Results: The present study is the first comprehensive species-level analysis of the Pterioidea to produce a wellresolved, robust phylogenetic hypothesis for nearly all extant taxa. The data were analyzed for potential biases due to taxon and character sampling, and idiosyncracies of different molecular evolutionary processes. The congruence and contribution of different partitions were quantified, and the sensitivity of clade stability to alignment parameters was explored. Conclusions: Four primary conclusions were reached: (1) the results strongly supported the monophyly of the Pterioidea; (2) none of the previously defined families (except for the monotypic Pulvinitidae) were monophyletic; (3) the arrangement of the genera was novel and unanticipated, however strongly supported and robust to changes in alignment parameters; and (4) optimizing key morphological characters onto topologies derived from the analysis of molecular data revealed many instances of homoplasy and uncovered synapomorphies for major nodes. Additionally, a complete species-level sampling of the genus Pinctada provided further insights into the on-going controversy regarding the taxonomic identity of major pearl culture species.

Résumé [+] [-]Carnivory is unusual among bivalve molluscs and is limited to a few families in the distantly related orders Pectinida, Mytilida and Anomalodesmata. Despite the significance of dietary shifts in the evolution of the bivalves, the anatomy of the alimentary system, and of the gastric chamber in particular, has been described in detail for only a few carnivorous species. Here we describe the anatomy of the gastric chamber in a pectinid, Propeamussium jeffreysii, and an anomalodesmatan, Bathyneaera demistriata, expanding the known morphological disparity of the alimentary system in both groups. We found the stomachs of both to be modified to varying degrees for a carnivorous habit, with thickened, muscular walls, extensive cuticular linings, and reduced sorting areas and gastric chamber compartments (i.e. the dorsal hood, the left pouch and the food-sorting caecum). Despite some superficial similarity, each retains distinct hallmarks of their ancestry among filter-feeding relatives, allowing precise homology assessment of individual characters to differentiate between them. In addition, we found that the gastric chamber of P. jeffreysii represents an intermediate morphology between previously described P. lucidum and filter-feeding pectinids. Consequently, variation in the anatomy of the gastric chamber in Pectinida parallels a previously identified trend towards greater specialization for carnivory in the Anomalodesmata. Our results indicate that the current classification scheme of stomach types does not reflect phylogenetic affinity across the Bivalvia and highlight the need for accurate homology assessment of individual characters of the gastric chamber for inferring evolutionary relationships.

Résumé [+] [-]Understanding how the extraordinary taxonomic and ecological diversity of cone snails (Caenogastropoda: Conidae) evolved requires a statistically robust phylogenetic framework, which thus far is not available. While recent molecular phylogenies have been able to distinguish several deep lineages within the family Conidae, including the genera Profundiconus, Californiconus, Conasprella, and Conus (and within this one, several subgenera), phylogenetic relationships among these genera remain elusive. Moreover, the possibility that additional deep lineages may exist within the family is open. Here, we reconstructed with probabilistic methods a molecular phylogeny of Conidae using the newly sequenced complete or nearly complete mitochondrial (mt) genomes of the following nine species that represent all main Conidae lineages and potentially new ones: Profundiconus teramachii, Californiconus californicus, Conasprella wakayamaensis, Lilliconus sagei, Pseudolilliconus traillii, Conus (Kalloconus) venulatus, Conus (Lautoconus) ventricosus, Conus (Lautoconus) hybridus, and Conus (Eugeniconus) nobilis. To test the monophyly of the family, we also sequenced the nearly complete mt genomes of the following three species representing closely related conoidean families: Benthomangelia sp. (Mangeliidae), Tomopleura sp. (Borsoniidae), and Glyphostoma sp. (Clathurellidae). All newly sequenced conoidean mt genomes shared a relatively constant gene order with rearrangements limited to tRNA genes. The reconstructed phylogeny recovered with high statistical support the monophyly of Conidae and phylogenetic relationships within the family. The genus Profundiconus was placed as sister to the remaining genera. Within these, a clade including Californiconus and Lilliconus + Pseudolilliconus was the sister group of Conasprella to the exclusion of Conus. The phylogeny included a new lineage whose relative phylogenetic position was unknown (Lilliconus) and uncovered thus far hidden diversity within the family (Pseudolilliconus). Moreover, reconstructed phylogenetic relationships allowed inferring that the peculiar diet of Californiconus based on worms, mollusks, crustaceans and fish is derived, and reinforce the hypothesis that the ancestor of Conidae was a worm hunter. A chronogram was reconstructed under an uncorrelated relaxed molecular clock, which dated the origin of the family shortly after the Cretaceous-Tertiary boundary (about 59 million years ago) and the divergence among main lineages during the Paleocene and the Eocene (56–30 million years ago).

Résumé [+] [-]The subfamily Cantharidinae Gray, 1857 (Trochoidea: Trochidae) includes 23 recognized genera and over 200 known living species. These marine top shell snails are microphagous grazers that generally live in shallow rocky shores and in macroalgae and seagrass beds of sub-tropical and temperate waters from the Central and Western Indo-Pacific biogeographic regions to the Mediterranean Sea and the Eastern Atlantic Ocean. Recent molecular phylogenetic studies revising the family Trochidae supported the monophyly of the subfamily Cantharidinae and its sister group relationship to the subfamily Stomatellinae. These studies and others has thus far mostly focused on Indo-Pacific members of the subfamily Cantharidinae whereas here, we investigated phylogenetic relationships among their counterparts from the Mediterranean Sea and the North-eastern (NE) Atlantic Ocean including 33 species of genera Gibbula, Jujubinus, Phorcus, Clelandella, and Callumbonella. The Mediterranean and NE Atlantic taxa were supplemented with 30 Indo-Pacific Cantharidinae species plus 19 members of the sister group subfamily Stomatellinae. Phylogenetic trees were constructed using Bayesian inference and maximum likelihood with two datasets comprised of partial sequences of four or six mitochondrial (cox1, rrnL, rrnS, and cob) and nuclear (28S rRNA and histone H3) genes. A clade comprised of all Mediterranean and NE Atlantic taxa was recovered with high support, but its sister group among the Indo-Pacific lineages could not be determined with confidence (although the assignment of “Trochus” kotschyi to Priotrochus could be rejected). Within the Mediterranean and NE Atlantic clade, genera Phorcus and Jujubinus were recovered as reciprocally monophyletic, and the deep-sea genera Clelandella and Callumbonella were placed with high support as sister to Jujubinus. However, the genus Gibbula as currently defined was not monophyletic and constituent species were divided into three major clades and two independent lineages. Phylogenetic relationships among Phorcus, Jujubinus (plus Clelandella and Callumbonella), and the different clades of Gibbula were not fully resolved but received higher support in the phylogenetic analyses based on six genes. A first approach to resolve phylogenetic relationships within Stomatellinae was conducted showing that the diversity of the subfamily is highly underestimated at present, and that Calliotrochus is possibly a member of this subfamily. A chronogram was reconstructed using an uncorrelated relaxed lognormal molecular clock and the origin of the Mediterranean and NE Atlantic clade was dated right after the Azolla phase in the Middle Eocene about 48 million years ago whereas diversification of major clades (genera) followed the eastern closure of the Tethys Ocean in the Middle Miocene about 14 million years ago.

Résumé [+] [-]Long-branch attraction (LBA) is a well-known artifact in phylogenetic reconstruction. Sparse taxon sampling and extreme heterogeneity of evolutionary rates among lineages generate propitious situations for LBA, even defying probabilistic methods of phylogenetic inference. A clear example illustrating LBA challenges is the difficulty of reconstructing the deep gastropod phylogeny, particularly using mitochondrial (mt) genomes. Previous studies consistently obtained unorthodox phylogenetic relationships due to the LBA between the mitogenomes of patellogastropods (true limpets, represented only by Lottia digitalis), heterobranchs, and outgroup taxa. Here, we use the reconstruction of the gastropod mitogenomic phylogeny as a case exercise to test the effect of key methodological approaches proposed to counteract LBA, including the selection of slow-evolving representatives, the use of different outgroups, the application of site-heterogeneous evolutionary models, and the removal of fast-evolving sites. In this regard, we sequenced three new patellogastropod mt genomes, which displayed shorter branches than the one of Lottia as well as gene organizations more similar to that of the hypothetical gastropod ancestor. Phylogenetic analyses incorporating the mt genomes of Patella ferruginea, Patella vulgata, and Cellana radiata allowed eliminating the artificial clustering of Patellogastropoda and Heterobranchia that had prevailed in previous studies. Furthermore, the use of site-heterogeneous models with certain combinations of lineages within the outgroup allowed eliminating also the LBA between Heterobranchia and the outgroup, and recovering Apogastropoda (i.e., Caenogastropoda + Heterobranchia). Hence, for the first time, we were able to obtain a mitogenomic phylogeny of gastropods that is congruent with both morphological and nuclear datasets.

Résumé [+] [-]The study of a large collection of cryptobranch dorid nudibranchs from deep waters in New Caledonia and the Philippines revealed the presence of Austrodods kerguelenensis (Bergh, 1884); 18 new species belonging to the genera Cadlina, Austrodoris, Geitodods, Discodoris, Peltodoris, Paradoris, Diaulula, Rostanga, Sclerodoris, Baptodoris and Dendrodoris, and two previously undescribed genera, Goslineria and Pharodoris, The anatomy of all these species, including the digestive, reproductive, and nervous system, are studied in detail. All these species are clearly distinguishable from other members of their genera. Most of the species have a pale, simple background coloration, and two of them lack eyes. Both characteristics seem to be adaptations to living in deep waters. Other deep-water Atlantic and Pacific species of dorid nudibranchs have similar adaptations. The two new genera are characterized by the presence of large copulatory spines, numerous flexible spines in Goslineria, and two solid, bifid spines in Pharodoris. No other cryptobranch dorid genera previously described have similar copulatory spines. Some of the species here described belong to genera previously reported from cold or temperate waters, such as Austrodoris, Cadlina and Diaulula. Most of the species belong to genera that are widespread in either cold, temperate or tropical waters (Rostanga, Paradoris, Geitodods and Baptodoris), and only two belong to exclusively tropical genera (Sclerodoris and Dendrodoris). Vicariant events and vertical dispersal could explain the processes of speciation and the origin of these deep-water species.

Résumé [+] [-]Material collected by deep-sea expeditions in the south-west Pacific Ocean reveals a previously unrecognized radiation of the family Phyllidiidae into deeper waters, with a couple of species having a bathymetric range confined below 500 m. Whereas the shallow-water « 100 m) radiation consists mainly of species of Phyllidia, species of Phyllidiopsis make over 70% of the fauna in the 100-500 m interval, and the only two taxa recorded in the 500-750 m interval are species of Phyllidiopsis. A parallel pattern is observed in the Atlantic. There are no consistent anatomical differences between congeneric shallow and deep-water species, but taxa from deeper water are paler and have a simpler dorsal morphology. Twelve new species are described: Phyllidia orstomi sp. novo (Norfolk Ridge, 270-300 m), Phyllidiopsis brunckhorsti sp. novo (New Caledonia, 290350 m), P. anomalasp. Novo (Norfolk and Loyalty Ridges, 240-310 m), P. holothuriana sp. novo (Norfolk Ridge and Vanuatu, 110-240 m), P. macrotuberculata sp. novo (Norfolk Ridge, 270-300 m), P. futunai sp. novo (off Futuna 1., NE of Fiji, 165 245 m),P. crucifera sp. novo (off Futuna 1.,105-160 m), P. lozoueti sp. Novo (Norfolk Ridge, 235 m), P. richeri sp. novo (Norfolk Ridge, 510-750 m), P. circularis sp. novo (Norfolk Ridge, 510-530 m), P. vanuatuensis sp. novo (off Tanna 1., Vanuatu, 410 m), and P. neocaledonica sp. novo (New Caledonia, 315 m).

Résumé [+] [-]The phylogenetic relationships of the caryophyllidia-bearing dorids are studied, based on the examination of the type species of all the genera previously described. The phylogenetic hypothesis supports that the caryophyllidia-bearing dorids are a monophyletic group and the sister group of the clade formed by Asteronotus Ehrenberg, 1831 and Halgerda Bergh, 1880. Several genera previously considered as valid or regarded as uncertain are here synonymized: Peronodoris Bergh, 1904, Trippa Bergh, 1877, Phlegmodoris Bergh, 1878, Petelodoris Bergh, 1881, Kentrodoris Bergh, 1876, Audura Bergh, 1878, Centrodoris P. Fischer, 1883, Anisodoris Bergh, 1898, Awuka Er. Marcus, 1955, Rhabdochila P. Fischer, 1883, Boreodoris Odhner, 1939, Dictyodoris Bergh, 1880, Gravieria Vayssière, 1912, Aporodoris Ihering, 1886. The following genera are regarded as valid: Asteronotus, Atagema J.E. Gray, 1850, Jorunna Bergh, 1876, Platydoris Bergh, 1877, Diaulula Bergh, 1878, Rostanga Bergh, 1879, Halgerda Bergh, 1880, Baptodoris Bergh, 1884, Gargamella Bergh, 1894, Alloiodoris Bergh, 1904, Sclerodoris Eliot, 1904, Taringa Er. Marcus, 1955, Thorybopus Bouchet, 1977. The new genus Nophodoris is described based on two new species from New Caledonia deep waters. Two additional new species from New Caledonia belonging to the genera Atagema and Gargamella are also described. Nomenclatural and taxonomic problems are discussed, and several type species, neotypes and lectotypes are selected.

Résumé [+] [-]There are six valid species in the traditional genus Bathydoris, all of them found in polar or deep waters: Bathydoris abyssorum Bergh, 1884 (from the deep equatorial Pacific Ocean), Bathydoris ingolfiana Bergh, 1899 (from Greenland), Bathydoris hodgsoni Eliot, 1907 (from Antarctic and subantarctic waters), Bathydoris clavigera Thiele, 1912 (from the Argentinean deep-sea basin and Antarctica), Bathydoris aioca Ev. Marcus and Er. Marcus, 1962 (from deep waters off California), and a new species, Bathydoris spiralis (from deep waters off New Caledonia). Bathydoris patagonica Kaiser, 1980 and Bathydoris violacea Baranets, 1993 are regarded as synonyms of B. hodgsoni and B. clavigera, respectively. Bathydoris spiralis is clearly distinguishable from other members of the genus mainly in having a triaulic reproductive system and a very elongated, spirally coiled deferent duct. Examination of the holotype of B. violacea revealed that it is a synonym of B. clavigera. Bathydoris vitjazi Minichev, 1969 is most likely a synonym of B. hodgsoni, but is provisionally regarded as nomen dubium until more material becomes available. The phylogenetic hypothesis supports the monophyly of the Anthobranchia but shows that the genus Bathydoris is paraphyletic. Species of Bathydoris are divided into two clades, one of them also containing the phanerobranch and cryptobranch dorids. Bathydoris type species B. abyssorum retains its name and diagnosis, but B. clavigera and B. spiralis are excluded from this genus. They are, however, provisionally maintained in "Bathydoris" s.l., a likely paraphyletic group. This result shows some incongruities between the traditional nomenclatural system and phylogenetic systematics.

Résumé [+] [-]One hundred and twenty-one species of deep sea “cephalaspidean” heterobranchs belonging to the genera Acteon, Crenilabium, Obrussena, Rictaxis, Japonacteon, Maxacteon, Bullina, Diaphana, Toledonia, Cylichna, Scaphander, Sabatia, Roxania, Cylichnium, Acteocina, Truncacteocina, Philine, Retusa, Pyrunculus, Volvulella, Relichna, Micratys, Gastropteron, Aglaja and Philinopsis are reported from the tropical southwest Pacifi c. Thirty-nine of these species are new: Acteon ionfasciatus, Acteon chrystomatus, Rictaxis sanguinea, Japonacteon longissimus, “Acteon” editus, “Acteon” buccinus, “Acteon” ringiculoides, “Acteon” boteroi, “Acteon” loyautensis, “Acteon” rhektos, “Acteon” profundus, “Acteon” osexiguus, “Acteon” aphyodes, “Acteon” herosae, “Acteon” comptus, “Acteon” chauliodous, “Acteon” cohibilis, Bullina rubropunctata, Toledonia neocaledonica, Toledonia epongensis, Cylichna tanyumphalos, Cylichna grovesi, Sabatia pyriformis, Roxania smithae, Cylichnium mucronatum, Cylichnium nanum, Acteocina lata, Philine habei, Philine babai, Philine abyssicola, Retusa diaphana, Retusa insolita, Retusa lenis, Retusa abyssicola, Retusa trunca, Volvulella onoae, Volvulella multistriata, Relichna hadra and Micratys wareni. A previously described species, Acteon aequatorialis, is included in the new genus Bathyacteon. Three species are assigned provisionally to already described species until more material becomes available: Acteon cf. nakayamai, Maxacteon cf. kawamurai, “Acteon” laetus. Thirty-eight species remain unnamed because of the absence of adequate information, but the shells are illustrated. Most species are described based on conchological data. Fourteen species of Acteonidae and two of Retusidae are provisionally assigned to the artifi cial taxa “Acteon” and “Retusidae” until anatomical data become available. The present collecting effort in the southwest Pacifi c has produced large numbers of previously undocumented species. The largest number of species was found in the area comprising the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna, which is probably a consequence of a greater collecting effort. The list of species refl ects a high degree of endemism in the deep sea fauna from the southwest Pacifi c. Only a few widespread Indo-Pacific species have been found in the deep sea. It also appears that there is some sort of isolation between the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna region and the Philippines and Indonesia region, which is refl ected in the small number of species shared between these two areas. Most species of “cephalaspidean” heterobranchs studied here have broad bathymetric ranges compared to other groups of opisthobranchs, which may be a result of a higher ecological adaptability of this group, or may be an artifact caused by transport of empty shells. When only specimens collected alive are considered, the bathymetric ranges of most species are considerably narrower. Most species studied are exclusively found in the deep sea, but a small number of shallow water species have been recorded here for the fi rst time in deep waters. When the ranges of empty shells are examined there appears to be a turnover of “cephalaspidean” heterobranch species at about 1000-1200 m depth and a blurry transition between shallow waters and the deep sea. When only specimens collected alive are considered, there is a sharp boundary at about 200 m that clearly separates the shallow water and the deep sea faunas. “Cephalaspidean” heterobranch species are more common relative to other groups of opisthobranchs in deep waters than in shallow waters, but this result may be an artefact caused by the collecting techniques.

Résumé [+] [-]The deep-water Cancellariidae collected during the KARUBAR cruise near the Kai and Tanimbar Islands are represented by 20 species (9 new), only two of which were recorded earlier from the Arafura Sea. As many as 14 species (70% of the total) are represented by single specimens, and 17 (85%) have been collected at one station only: this points to a still more diverse cancellariid fauna. New species of Axelella, Perplicaria, and Solatia represent the first occurence of these genera in the Indo-West Pacific. Admete aethiopica Thiele, 1925, recently suspected to be a species of Turridae, is confirmed as a cancellariid.

Résumé [+] [-]The genera Cantharus Röding, 1798, Pollia Gray in Sowerby, 1834, and Cancellopollia n.g. (type species : C. gracilis n. sp.) are pisaniine buccinids having a small tooth (labral spine) at the edge of the crenulated outer lip. As defined and restricted here, these genera have a mainly Indo-West Pacific distribution. Cantharus septemcostatus n. sp. , Pollia pellita n. sp., Cancellopollia gracilis n. sp. , and C. ustulata n. sp., are reported from deep water in the New Caledonia region, and Cantharus leucotaeniatus Kosuge, 1985 and Pollia vicdani (Kosuge, 1984) n. comb. are from the Vanuatu. Despite a narrow bathymetric (4154-560 m) and horizontal (northernmost Norfolk Ridge) distribution, Cancellopollia gracilis exhibits remarkable variation, with highly localised morphs.

Résumé [+] [-]The Cardiid genus Fulvia is revised based on examination of type material and over 900 lots in relevant muséums. Characters of shell sculpture are regarded as taxonomically more reliable than shape and colour, hitherto the base of spécifie taxonomy in the genus. It is established that Fulvia shares vvith l’epncardium numerous characters, including the présence of ocular organs on siphonal tentacles, and is included hère in the tribe VEPRICARDIINI. Laevifulvia subgen nov. (Type species: F. undatopicta Pilsbry, 1904) is segregated from Fulvia s.s., based on the lack of periostracal insertions on the ribs. Sixteen Indo-Pacific species of récent Fulvia are recognized, of which six are new. The name F. papyracea, hitherto used for a conimon Indo-West Pacific species is shown to represent a rare and restricted species. The name F. fragilis (Forsskal in Niebuhr, 1775) is to be used for most usages of F. papyracea of authors.

Vidal J. 1999. Taxonomic review of the elongated cockles: Genera Trachycardium, Vasticardium and Acrosterigma (Mollusca, Cardiidae). Zoosystema 21(2): 259-335
Résumé [+] [-]The cardiids of the subfamily Trachycardiinae Stewatt, 1930 (sensu Keen, 1969, genus Papyridea excluded), are reviewed, with special attention given to the geneta Trachycardium, Acrosterigma, and Vasticardium. No change is proposed here to the relatively well-defined taxonomy of Trachycardium, consideted to be exclusively American, with six subgenera, nor to the American Acrosterigma. In contrast, the generic taxonomy of the Indo-Pacific Trachycardiinae, quasi-randomly distributed by authors among the three genera cited above, was not clear and is reevaluated. All of the species are regrouped here into two genera Vasticardium and Acrosterigma which receive clear and usable definitions. The American genus Trachycardium differs widely from them in both hinge and rib morphology. The two genera Vasticardium and Acrosterigma are distinguished mainly by rib motphology. These three genera are now grouped in the subfamily Cardiinae. In several previous articles, I have analyzed in detail the genus Vasticardium, including fifteen Recent species. The results are summarized here. The genus Acrosterigma is represented in America by several fossil species and two Recent species; in the Indo-Pacific, where no general study has previously been undettaken, it is represented by several fossil species (one new) and twenty-five Recent species, of which nine are new; these species are divided into six species-groups. Neotypes ate proposed for Cardium magnum Linné, 1758 and Cardium biradiatum Bruguière, 1789 and lectotypes for Cardium laevigatum Linné, 1758, Cardium serratum Linné, 1758, and Cardium marmoreum Lamarck, 1819.

Vidal J. & Kirkendale L. 2007. Ten new species of Cardiidae (Mollusca, Bivalvia) from New Caledonia and the tropical western Pacific. Zoosystema 29(1): 83-107
Résumé [+] [-]The fauna of the tropical Indo-west Pacific is exceptionally diverse but poorly known with even relatively well-studied faunal components yielding new species after careful study, novel approaches (e.g., delineation of cryptic species via molecular analyses) and/or rigorous collection efforts. In an attempt to quantify the biodiversity of the western Pacific molluscan fauna, comprehensive, systematic collecting expeditions have been made since 1978, with a focus on New Caledonia. Building on earlier studies of cardiids from the western Pacific, we report one new genus of cardiid (Pseudofulvia n. gen.) and 10 new cardiid taxa from the area: Acrosterigma capricorne n. sp., Fulvia (Fulvia) colorata n. sp., F. (F.) vepris n. sp., F. (Laevifulvia) subquadrata n. sp., F. (L.) imperfecta n. sp., Pseudofulvia caledonica n. gen., n. sp., P. arago n. gen., n. sp., Ctenocardia gustavi n. sp., C. fi jianum n. sp., C. (Microfragum) subfestivum n. sp. The new species are easily differentiated from conspecifics in details of hinge, dentition, lunular shape and area, rib number and/or rib ornamentation, but often diff er in gross morphological features, such as coloration, shape and size as well. Ctenocardia gustavi n. sp., C. (Microfragum) subfestivum n. sp. and Pseudofulvia caledonica n. gen., n. sp. are relatively large-bodied, with a wide distribution throughout the western Pacifi c. In contrast, Acrosterigma capricorne n. sp. and Pseudofulvia arago n. gen., n. sp. are known only from the Austral Islands and considering the intensive collecting efforts in the region, they appear restricted in their distributions.

New genus and new species of Solariellidae (Gastropoda: Trochoidea) from New Caledonia, Fiji, Vanuatu, Solomon Islands, Philippines, Papua New Guinea and French Polynesia, in Héros V., Strong E.E. & Bouchet P.(Eds), Tropical Deep-Sea Benthos 29. Mémoires du Muséum national d’Histoire naturelle 208. Muséum national d'Histoire naturelle, Paris:267-289, ISBN:978-2-85653-774-9
Résumé [+] [-]Elaphriella n. gen. is a new genus of small to fairly large (up to 18 mm) solariellids superficially resembling the genus Archiminolia Iredale, 1929. The latter differs, among others, by a much thicker columella, spiral cords or grooves that often continue on the body whorl and spiral cords inside the umbilicus. The two genera form distinct clades in a molecular phylogeny of the family Solariellidae. Seven new species are described, all from deep water (300-900 meters) in the South and West Pacific: Elaphriella cantharos n. sp., E. eukhonikhe n. sp., E. paulinae n. sp., E. wareni n. sp., E. dikhonikhe n. sp., E. helios n. sp. and E. leia n. sp.

Résumé [+] [-]Before talking about a largely underestimated and poorly known, yet so beautiful family of Gastropoda, there is an issue which I must attract your attention to. While gathering the necessary information, shells and literature, I often wondered why people still call some of the Tonnidae by the wrong name, despite the sometimes meticulous research done by scientists in the past. Is it because of the often controversial information in the available publications? Is it for lack of decent information? This issue became clear to me when I was looking into the most recent publications on Eudolium such as Piani (1977), Marshall (1992) and Bouchet & Waren (1993). All concluded that what is usually sold as Eudolium pyriforme is in fact Monterosato 's true Eudolium crosseanum. I must say I was a bit shocked to read those papers and see some photographs of the type material. Why were erroneous names still used ifproofwas there, clearly and undoubtedly, to the contrary? It took me a few weeks and a few discussions with Dr Philippe Bouchet and Dr Alan Beu to figure it out, but in the end, the answer is simple: In scientific terms, proof is given by photography and description, and maybe by discussion, but not in such words or language that they are understandable to the untrained reader. Also, such research is often documented in broader publications (e.g. Bouchet & Waren, 1993; Beu, 2005) that don't attract the attention of the advanced amateur or naturalist straight away, and are wrongfully neglected. These works are seldom offered commercially, and thus unjustly remain unknown to the wider public. It is in this respect that works such as the Concho logical Iconography, often written by advanced naturalists, have their true value and Guido Poppe, Klaus Groh and Yves Terryn must be commended for an initiative such as this is an excellent medium to bring science and amateur collecting closer together in an attempt to cover the gap between the two. It is my ambition to give a synoptical overview ofthe existing (described) species, based on my collection of well over 1000 specimens and an ever-increasing library of historical as well as recent publications. Ten years of collecting and studying shells and publications have resulted in what is to follow. I have listed the most important synonyms for each species in order to clarify some of the dubious issues, but the lists are not exhaustive. Although I have many of the old publications through digital photography, I'm sure that there are still many more out there. And even if I was to spend another month in the libraries of, e.g. the BM(NH) or the MNHN, there will still be publications "hidden" somewhere. I mainly concentrate my research on Recent material, whilst a lot has been described in the fossil area as well. For example: recently, Dr Alan Beu discovered that there is an earlier name for what we all know as Eudolium pyriforme (G. B. Sowerby III, 1914), namely Eudolium javanum (Martin, 1879), originally described as the fossil Cassidariajavana from the late Miocene oflndonesia. While researching this, he also discovered names such as Dolhun hochstetteri Martin, 1879 (= Tonna allium (Dillwyn, 1817)) just to give one example. Another issue is interpretation. Many have interpreted, e.g. Adanson's "Le Minjac" in different ways. For one author, it is T. marginata (Philippi, 1845), for another author T. tessellata (Lamarck, 1816). March (1852) even lists it as a full species, D. minjac. In order to clarify such matters, I have tried to compare specimens with type material. This publication should be a solid basis for any future researcher in this family and I do hope you will all find the necessary answers to your basic tun-related questions to start that collection you always wanted to start.

Wakefield A. & Mccleery T. 2004. New species of Granulina and Gibberula (Gastropoda: Cystiscidae) from offshore subtidal habitats in the western Fijiian Islands. Novapex 5(2-3): 69-78
Résumé [+] [-]Four new cystiscid species (two Granulina and two Gibberula) are described from samples dredged from offshore subtidal habitats off the Western Fijiian Islands. Granulina globosa sp. nov. is compared with similar species, and the surface microsculpture of the shell is presented to add to the body of evidence supporting this as an important characteristic of the genus. The generic placement of Granulina mamanucensis sp. nov. is discussed in depth. Gibberula marinae sp. nov. is considered to be a member of the group 'philippi', a widespread group of small white shelled Gibberula with variable animal chromatism. Gibberula vomoensis sp. nov., an extremely small species with an unusual morphology, is described. The bathymetry distribution of marginellid and cystiscid genera in Fijiian waters is commented upon.

Wakefield a. 2010. A revision of the genus Cryptospira Hinds, 1844 (Caenogastropoda: Marginellidae). Novapex 11(HS 7): 1-55
Résumé [+] [-]The marginellid genus Cryptospira Hinds, 1844 is revised on the basis of characteristic shell morphologies. Three species groups within the genus are proposed; the Cryptospira tricincta group, the Cryptospira ventricosa group and the Cryptospira elegans group. The recent species and the fossil species are presented and discussed separately. In the first section, all of the taxa in the Cryptospira tricincta group are revised and updated. Of the nine published taxa, six (Marginella tricincta Hinds, 1844; M. onychina A. Adams & Reeve, 1848; C. quadrilineata Gaskoin, 1849; M immersa Reeve, 1865; M. fischeri Bavay, 1902; C. sabelli Cossignani, 2006) are considered to be valid species, and three are considered to be synonyms (M ovalis Marrat, 1881 and C. quiquandoni Cossignani, 2006 are junior synonyms of M tricincta Hinds, 1844, and M quadrilineata Reeve, 1864 is a junior synonym of C. quadrilineata Gaskoin, 1849). From an argument based upon regional differences in shell morphology, the phenotypes currently accepted as C. tricincta are assumed to be a complex of species and/or subspecies. Further division of the C. tricincta group into three sub-groups is also proposed on the basis of morphologie features, and three new species are described: C. wallacei n.sp. From the Makassar Strait, Eastern Kalimantan, C. cloveriana n. sp. From Taiwan to Singapore, and C. mccleeryi n. sp. From the Gulf of Thailand. The Cryptospira ventricosa group comprises six published taxa, three of which are valid species, namely M ventricosa G. Fischer von Waldheim, 1807, M dactylus Lamarck, 1822 and M trailii Reeve, 1865. Three further taxa are considered to be junior synonyms of M ventricosa (M quinqueplicata Lamarck, 1822; M vermiculata Redfield, 1851 ; M hainesii Petit, 1851) and one dubious name, Voluta porcellana Perry, 1811 is also discussed. The Cryptospira elegans group comprises thirteen published taxa of which seven are considered valid species; Voluta elegans Gmelin, 1791 ; V strigata Dillwyn, 1817 (synonym M undulata Deshayes, 1844, with M Bernardii Largilliert, 1845 introduced as a new synonym); C. marchii Jousseaume, 1875 (removed from the synonymy of V strigata Dillwyn, 1817 and elevated to valid species status. M Burchardi Reeve, 1864 is transferred from the synonymy of V strigata Dillwyn, 1817 to the synonymy of C. marchii); M praecallosa Higgins, 1876 (previously considered by authors to be a synonym of V strigata Dillwyn, 1817, with M loebbeckeana Weinkauff, 1878 introduced as a new synonym); C. glauca Jousseaume, 1875 ; Persicula grisea Jousseaume, 1875 (senior synonym M obtusa Sowerby, 1870 and junior synonym M sexplicata Weinkauff, 1879); and M scripta Hinds, 1844. The holotype of M loebbeckeana Weinkauff, 1878 is rediscovered, and this taxon is considered not to be a variety of C. glauca Jousseaume, 1875 as commonly accepted, but rather a junior synonym of the valid M praecallosa Higgins, 1876, here considered as a valid species. C. bridgettae n. sp. From the Andaman Sea is described as a new species in the Cryptospira elegans group. Three taxa occurring exclusively as fossils from the Indonesian Pleistocene have been published (C. sangiranensis Martin, 1906; C. dacty/us var. inflata Martin 1895; M birmanica Vredenburg, 1923), and all are considered to be extinct. Eight further fossil phena comprising three forms of M tricincta Hinds, 1844 (one a synonym named C. quinqueplicata var. minor Martin, 1931 ), M. ventricosa Fischer von Waldheim, 1807, M dactylus Lamarck, 1822 (synonym M dactylus var. Minor Pannekoek, 1936), V. elegans Gmelin, 1791 (synonym M (C.) ex aff elegans Oostinghe, 1938), V strigata Dillwyn, 1917 (synonym M (C.) aff loebbeckeana Oostinghe, 1938) and M trailii Reeve, 1865 are considered to match recent species. Two new fossil species of Ctyptospira from the tate Pliocene of Sangiran, central Java, are described; C. bundharmai n. sp. From Sambang Macan, and C. kemukusi n. sp. From Kemukus. Both are considered to be extinct. In examing the phylogenic relationships of the genus, evidence from the fossil record and comparative analysis of the radula of recent species point towards a relatively recent evolution of the genus as an adaptive radiation from the main Prunum / Volvarina stock into the region of the Sunda Shelf, probably during the last 3-5 million years. The current biogeographie distribution of the genus is examined and three species group radiations from a central evolutionary zone, where species diversity is at its greatest are proposed.

Résumé [+] [-]The classification of Tonnoidea is discussed based on new information about deep-sea species. Representative radular, opercula, and larval shells are described and figured. The conclusions agree mainly with earlier classification, with the following execptions:Oocorythinae is moved from Tonnoidea to Cassidae and its value as a subfamily is questioned. The gross anatomies of two Recent deep-water species of Pisanianura Rovereto, 1889, are described, and a new ranellid subfamily, Pisanianurinae, is described for Pisanianura Rovereto, 1889, formely classified in the Buccinidae. The genera Laminilabrum Kuroda & Habe, 1961, presently in the Trichotropidae, Kaiparanura Laws, 1944, and Nawenia Ladd, 1977, presently in the Buccinidae, are considered synonyms of Pisanianura, which is known in the fossil record since the Oligocene. A new family, Laubierinidae, is erected for Laubierina gen. nov. And Akinumia Kuroda & Habe, 1958 (formerly Trichotropidae) with three Recent deep-water species. Laubierina peregrinator gen. et sp. nov. is described from deep water in the tropical Atlantic and Indian oceans. Two large (5 mm) planktonic larvae belonging to the Laubierinidae are described and one of them is remarkable for being a sexually mature male at the time of settlement. All dissected adults are females and it is speculated that Laubierinidae is a protandrous hermaphrodite with neotenic males. The gross anatomies of L. peregrinator sp. nov. , A. orientalis (Schepman, 1909), and A. shepmani (Habe, 1962) are described. Akibumia reticulata Habe, 1962, is referred to Epitoniidae and Conradia minuta Golikov & Starobogatov, 1986 (described in Fossaridae) is considered a larva of Neptunellinae. Thalassocyon bonus Barnard, 1960, and T. tui Dell, 1967, are synonymized; their anatomies are briefly described and compared with that of Ficus and it is concluded that Thalassosyon has been correctly referred to the Ficidae. Attention is drawn to the fact that the morphology of the ficidae conforms poorly with other Tonnoidae. The value and use of larval shells as taxonomical criteria are discussed, and it is concluded that they are usefull criteria, as long as clear distinction is made betwenn "primary" (i. e., planktotrophic) and "secondary" (i.e., non-planktotrophic) types of larval shells and only "primary" ones are compared.

The following new species are described: Frovina angularis Warén & Hain (New Caledonia, bathyal), Zerotulaincognita Warén & Hain (North Atlantic, abyssal), Z. stellapolaris Warén & Hain (Antarctic), Z. coronata Warén & Hain (New Zealand, shelf), Trilirata sexcarinata Warén & Hain (Antarctic), T. triregis Warén & Hain (New Zealand, shelf), and T. herosae Warén & Hain (New Caledonia, bathyal). The anatomy is described for Frovina soror Thiele, 1912, F. indecora (Thiele, 1912), Zerotula stellapolaris, Trilirata macmurdensis (Hedley, 1911 ), T. sexcarinata, and D. labioflecta. Antitrichotropis wandelensis (Lamy, 1906) (former! Y in Capulidae, Neotaenioglossa) is transferred to Laevilitorininae (Littorinidae), based on examination of radula and external morphology of the headfoot. Lt is classified in Laevilitorina, subgenus Pellilacunella.

Résumé [+] [-]The assignment of species to the vetigastropod genus Solariella Wood, 1842, and therefore the family Solariellidae Powell, 1951, is complicated by the fact that the type species (Solariella maculata Wood, 1842) is a fossil described from the Upper Pliocene. Assignment of species to genera has proved difficult in the past, and the type genus has sometimes acted as a ‘wastebasket’ for species that cannot easily be referred to another genus. In the light of a new systematic framework provided by two recent publications presenting the first molecular phylogenetic data for the group, we reassess the shell characters that are most useful for delimiting genera. Shell characters were previously thought to be of limited taxonomic value above the species level, but this is far from the case. Although overall shell shape is not a reliable character, our work shows that shell characters, along with radular and anatomical characters, are useful for assigning species to genera. Sculpture of the early teleoconch (the region immediately following the protoconch) and the columella are particularly useful characters that have not been used regularly in the past to distinguish genera. However, even with the combination of all morphological characters used in this study (shell, radular and eye), a few species are still difficult to assign to genera and in such cases molecular systematic data are essential. In the present study, we discuss 13 genera—12 of which were recovered as well-supported clades in recent molecular systematic studies—and provide morphological characters to distinguish them. We describe several new taxa: Chonospeira n. gen. (referred to as ‘clade B’ in previous molecular systematic studies), Phragmomphalina n. gen. (Bathymophila in part in molecular systematic studies) and Phragmomphalina vilvensi n. sp. (type species of Phragmomphalina n. gen.). We synonymize Hazuregyra Shikama, 1962 with Minolia A. Adams, 1860, Minolia subangulata Kuroda & Habe, 1952 with Minolia punctata A. Adams, 1860 and M. gemmulata Kuroda & Habe, 1971 with M. shimajiriensis (MacNeil, 1960). We also present the following new combinations: Bathymophila bairdii (Dall, 1889), B. dawsoni (Marshall, 1979), B. regalis (Marshall, 1999), B. wanganellica (Marshall, 1999), B. ziczac (Kuroda & Habe in Kuroda, Habe & Oyama, 1971), Chonospeira nuda (Dall, 1896), C. iridescens (Habe, 1961), C. ostreion (Vilvens, 2009), C. strobilos (Vilvens, 2009), Elaphriella corona (Lee & Wu, 2001), E. diplax (Marshall, 1999), E. meridiana (Marshall, 1999), E. olivaceostrigata (Schepman, 1908), E. opalina (Shikama & Hayashi, 1977), Ilanga norfolkensis (Marshall, 1999), I. ptykte (Vilvens, 2009), I. zaccaloides (Vilvens, 2009), Minolia shimajiriensis (MacNeil, 1960), M. watanabei (Shikama, 1962), Phragmomphalina alabida (Marshall, 1979), P. diadema (Marshall, 1999), P. tenuiseptum (Marshall, 1999), Spectamen euteium (Vilvens, 2009), S. basilicum (Marshall, 1999), S. exiguum (Marshall, 1999) and S. flavidum (Marshall, 1999).

Résumé [+] [-]This study is the most extensive molecular study of the gastropod families Trochidae and Calliostomatidae published to date, in terms of both numbers of taxa and of gene sequences. As a result of Bayesian phylogenetic analyses of molecular sequence data from one nuclear gene and three mitochondrial genes, we propose dramatic changes to Trochidae family systematics, present the first molecular phylogeny for Calliostomatidae and include the first published sequence data for the enigmatic subfamily Thysanodontinae. Our phylogeny demonstrates that within the family Trochidae there is strong support for three subfamilies new to traditional classifications: Alcyninae subfam. nov., Fossarininae and Chrysostomatinae subfam. nov. As proposed, Alcyninae consists only of the nominotypical genus Alcyna, which is sister to all other trochids. The subfamily Fossarininae, as defined here, includes Fossarina, Broderipia, Synaptocochlea and ‘‘Roya” eximia and probably also Clydonochilus and Minopa. The subfamily Chrysostomatinae comprises the genera Chrysostoma and Chlorodiloma. Additional molecular support is also obtained for recently redefined Trochinae, Monodontinae, and Cantharidinae and for the traditionally recognised subfamilies Umboniinae and Stomatellinae. The subfamily Lirulariinae is not supported by the molecular data, but rather is incorporated into Umboniinae. We also demonstrate that the current concept of the subfamily Margaritinae (previously a trochid subfamily, but recently and provisionally assigned to Turbinidae) is not monophyletic. We provide preliminary evidence that whereas Margarella rosea (previously a member of Margaritinae) belongs in the trochid subfamily Cantharidinae, its presumptive congener M. antarctica is not a trochid, but instead clusters with the thysanodontine genus Carinastele. Based on the phylogenetic placement of C. kristelleae, we agree with previous proposals based on morphological data that Thysanodontinae are more closely related to Calliostomatidae than Trochidae. Both Calliostoma and Carinastele are carnivorous and if a sister relationship can be confirmed between Carinastele and Margarella antarctica it might mean that carnivory evolved twice in Trochoidea. The direction of dietary changes was not investigated in this study, but mapping diet onto the phylogeny suggests that true herbivory is predominantly a derived character. The new classification system also means that five trochid subfamilies are predominantly associated with hard substrata, one with soft substrata (Umboniinae) and two with algae and seagrass (Alcyninae and Cantharidinae). There has been a shift back to hard substrata in one umboniine clade. Two of three clades within Calliostomatidae were predominantly associated with hard substrata, but one Japanese clade is associated with sand. The finding of three new, unidentified species from very deep water means that Trochidae, like Calliostomatidae, now includes species found at bathyal depths. More deep-water species may be found as increased sampling leads to the discovery of new species.

Résumé [+] [-]The gastropod superfamily Trochoidea Rafinesque, 1815 is comprised of a diverse range of species, including large and charismatic species of commercial value as well as many small or enigmatic taxa that are only recently being represented in molecular studies. This study includes the first sequences for rarely collected species from the genera Gaza Watson, 1879, Callogaza Dall, 1881, Antimargarita Powell, 1951 and Kaiparathina Laws, 1941. There is also greater taxon sampling of genera that have proved difficult to place in previous phylogenetic analyses, like Tectus Montfort, 1810, Tegula Lesson, 1832, Margarites Gray, 1847, Margarella Thiele, 1893 and trochoid skeneimorphs. There is also greater sampling of poorly represented families Solariellidae and Liotiidae. Bayesian analysis of combined gene data sets based on four (28S, 12S, 16S and COI) or five genes (plus 18S) suggests that there are eight, possibly nine families in Trochoidea including the families Margaritidae and Tegulidae, which are recognized for the first time at familial rank. Other trochoidean families confirmed are Calliostomatidae, Liotiidae, Skeneidae, Solariellidae, Trochidae and Turbinidae. A clade including Cittarium and the commercially important genera Rochia and Tectus may represent a possible ninth family, but this is not formally recognized or described here and awaits confirmation from further studies. Relationships among families were not generally well supported except in the 5-gene tree. In the 5-gene tree, Turbinidae, Liotiidae, Tegulidae, Cittarium, Rochia and Tectus form a well-supported clade consistent with the previous molecular and morphological studies linking these groups. This clade forms another well-supported clade with Margaritidae and Solariellidae. Trochidae is sister to Calliostomatidae with strong support. Subfamilial relationships within Trochidae are consistent with recent molecular studies, with the addition of one new subfamily, Kaiparathininae Marshall 1993 (previously a tribe). Only two subfamilies are recognized within Turbinidae, both with calcareous opercula: Prisogasterinae and Turbininae. Calliostomatidae includes a new subfamily Margarellinae. Its assignment to Calliostomatidae, although well supported by molecular evidence, is surprising considering morphological evidence.

Cenozoic climate change and diversification on the continental shelf and slope: evolution of gastropod diversity in the family Solariellidae (Trochoidea). Ecology and Evolution 3(4): 887-917. DOI:10.1002/ece3.513
Résumé [+] [-]Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still few in number. In this study, we had access to the largest number of solariellid gastropods ever collected for molecular studies, including many rare and unusual taxa. We used a Bayesian chronogram of these deep-sea gastropods (1) to test the hypothesis that deep-water communities arose onshore, (2) to determine whether Antarctica acted as a source of diversity for deep-water communities elsewhere and (3) to determine how factors like global climate change have affected evolution on the continental slope. We show that although fossil data suggest that solariellid gastropods likely arose in a shallow, tropical environment, interpretation of the molecular data is equivocal with respect to the origin of the group. On the other hand, the molecular data clearly show that Antarctic species sampled represent a recent invasion, rather than a relictual ancestral lineage. We also show that an abrupt period of global warming during the Palaeocene Eocene Thermal Maximum (PETM) leaves no molecular record of change in diversification rate in solariellids and that the group radiated before the PETM. Conversely, there is a substantial, although not significant increase in the rate of diversification of a major clade approximately 33.7Mya, coinciding with a period of global cooling at the EoceneOligocene transition. Increased nutrients made available by contemporaneous changes to erosion, ocean circulation, tectonic events and upwelling may explain increased diversification, suggesting that food availability may have been a factor limiting exploitation of deep-sea habitats. Tectonic events that shaped diversification in reef-associated taxa and deep-water squat lobsters in central Indo-West Pacific were also probably important in the evolution of solariellids during the Oligo-Miocene.

Résumé [+] [-]Adaptations to habitats lacking light, such as the reduction or loss of eyes and pigmentation, have fascinated biologists for centuries, yet have rarely been studied in the deep sea, the earth's oldest and largest light‐limited habitat. Here, we investigate the evolutionary loss of shell pigmentation, pattern, and eye structure across a family of deep‐sea gastropods (Solariellidae). We show that within our phylogenetic framework, loss of these traits evolves without reversal, at different rates (faster for shell traits than eye structure), and over different depth ranges. Using a Bayesian approach, we find support for correlated evolution of trait loss with increasing depth within the dysphotic region. A transition to trait loss occurs for pattern and eye structure at 400–500 m and for pigmentation at 600–700 m. We also show that one of the sighted, shallow‐water species, Ilanga navakaensis, which may represent the “best‐case” scenario for vision for the family, likely has poor spatial acuity and contrast sensitivity. We therefore propose that pigmentation and pattern are not used for intraspecific communication but are important for camouflage from visual predators, and that the low‐resolution vision of solariellids is likely to require high light intensity for basic visual tasks, such as detecting predators.

Résumé [+] [-]For over a decade now, High Throughput sequencing (HTS) approaches have revolutionized phylogenetics, both in terms of data production and methodology. While transcriptomes and (reduced) genomes are increasingly used, generating and analyzing HTS datasets remain expensive, time consuming and complex for most nonmodel taxa. Indeed, a literature survey revealed that 74% of the molecular phylogenetics trees published in 2018 are based on data obtained through Sanger sequencing. In this context, our goal was to identify the strategy that would represent the best compromise among costs, time and robustness of the resulting tree. We sequenced and assembled 32 transcriptomes of the marine mollusk family Turridae, considered as a typical non-model animal taxon. From these data, we extracted the loci most commonly used in gastropod phylogenies (cox1, 12S, 16S, 28S, h3 and 18S), full mitogenomes, and a reduced nuclear transcriptome representation. With each dataset, we reconstructed phylogenies and compared their robustness and accuracy. We discuss the impact of missing data and the use of statistical tests, tree metrics, and supertree and supermatrix methods to further improve phylogenetic data acquisition pipelines. We evaluated the overall costs (time and money) in order to identify the best compromise for phylogenetic data sampling in non-model animal taxa. Although sequencing full mitogenomes seems to constitute the best compromise both in terms of costs and node support, they are known to induce biases in phylogenetic reconstructions. Rather, we recommend to systematically include loci commonly used for phylogenetics and taxonomy (i.e. DNA barcodes, rRNA genes, full mitogenomes, etc.) among the other loci when designing baits for capture.

Résumé [+] [-]Abstract The practice of species delimitation using molecular data commonly leads to the revealing of species complexes and an increase in the number of delimited species. In a few instances, however, DNA-based taxonomy has led to lumping together of previously described species. Here, we delimit species in the genus Cryptogemma (Gastropoda: Conoidea: Turridae), a group of deep-sea snails with a wide geographical distribution, primarily by using the mitochondrial COI gene. Three approaches of species delimitation (ABGD, mPTP and GMYC) were applied to define species partitions. All approaches resulted in eight species. According to previous taxonomic studies and shell morphology, 23 available names potentially apply to the eight Cryptogemma species that were recognized herein. Shell morphometrics, radular characters and geographical and bathymetric distributions were used to link type specimens to these delimited species. In all, 23 of these available names are here attributed to seven species, resulting in 16 synonymizations, and one species is described as new: Cryptogemma powelli sp. nov. We discuss the possible reasons underlying the apparent overdescription of species within Cryptogemma, which is shown here to constitute a rare case of DNA-based species lumping in the hyper-diversified superfamily Conoidea.

Résumé [+] [-]Even though their occurrence was reported a long time ago, sunken wood ecosystems at the deep-sea floor have only recently received specific attention. Accumulations of wood fragments in the deep sea create niches for a diverse fauna, but the significance of the wood itself as a food source remains to be evaluated. Pectinodonta sp. is a patellogastropod that exclusively occurs on woody substrates, where individuals excavate deep depressions, and is thus a potential candidate for a wood-eating lifestyle. Several approaches were used on Pectinodonta sampled close to Tongoa island (Vanuatu) to investigate its dietary habits. Host carbon is most likely derived from the wood material based on stable isotopes analyses, and high cellulase activity was measured in the digestive mass. Electron microscopy and FISH revealed the occurrence of two distinct and dense bacterial communities, in the digestive gland and on the gill. Gland-associated 16S rRNA gene bacterial phylotypes, confirmed by in situ hybridization, included members of three divisions (Alpha- and Gammaproteobacteria, Bacteroidetes), and were moderately related (90-96% sequence identity) to polymer-degrading and denitrifying bacteria. Gill-associated phylotypes included representatives of the Delta- and Epsilonproteobacteria. The possible involvement of these two bacterial communities in wood utilization by Pectinodonta sp. is discussed.

Résumé [+] [-]During two expeditions to seamounts near the Mariana Trench in the tropical western Pacific, several trochiform shells from the upper bathyal zone were sampled. Morphological observations of these specimens suggest that they represent two new species that belong to the family Trochidae, but the shell morphology, radular plan, and external anatomy differ considerably from those of closely related genera. A new subfamily, Carinotrochinae subfam. nov., and a new genus, Carinotrochus gen. nov., are proposed herein to accommodate these two species. Carinotrochus marianaensis sp. nov., the type species, was associated with coral debris at a depth of 865 m, and Carinotrochus williamsae sp. nov. was discovered crawling on a hydroid Stegolaria sp. that was attached to a dead bamboo coral at a depth of 1332 m. Genertic analysis of mitochondrial COI, 16S rRNA, and nuclear 28S rRNA genes using maximum likelihood, Bayesian inference, and pairwise uncorrected p-distances confirmed that the new taxa are trochids but do not belong to any existing defined subfamily. Molecular clock analysis based on concatenated sequences (COI, 16S, and 28S) indicated that Carinotrochinae subfam. nov. split from its shallow water sister subfamily Trochinae roughly 80 Mya during the Late Cretaceous.

Résumé [+] [-]During the examination of a large suite of tropical deep-water molluscs, a number of Solenogastres were found, some of them typically curled around gorgonian stems. A subsequent closer examination of the Solenogastres revealed another type of object also curled around the gorgonians, which strongly resembled Solenogastres but lacked their external features. These objects proved to be cocoons with egg capsules, each containing two eggs or young larvae, typical of the parasitic platyhelminth group Fecampiida.

Résumé [+] [-]Recent examinations of newly obtained materials of dracunculoid nematodes (Dracunculoidea) parasitizing marine fishes off New Caledonia, South Pacific, revealed the presence of several nematodes of the genera Philometra Costa, 1845 (Philometridae) and Ichthyofilaria Yamaguti, 1935 (Guyanemidae), including the following four new species: Philometra priacanthi sp. n. (males) from the gonads of Priacanthus hamrur (Forsskal) (Priacanthidae), Philometra tenuicauda sp. n. (male and mature and gravid females) from the gonads of Lagocephalus sceleratus (Gmelin) (Tetraodontidae), Philometra dentigubernaculata sp. n. (males) from the oculo-orbit of Tylosurus crocodilus (Peron et Lesueur) (Belonidae), and Ichthyofilaria novaecaledoniensis sp. n. (subgravid female) from the musculature of Hoplichthys citrinus Gilbert (Hoplichthyidae). The new species are characterized mainly by the length and structure of spicules and the gubernaculum, body size, location in the host and by the type of hosts. In addition, the findings of Philometra lethrini Moravec et Justine, 2008 from the gonads of Lethrinus miniatus (Forster) and L. variegatus Valenciennes (both Lethrinidae) represent new host records for this parasite; for the first time, its subgravid females were found to be up to 350 mm long. The occurrence of Philometra ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002 in the oculo-orbit of Epinephelus areolatus (Forsskal) (Serranidae) off New Caledonia was confirmed.

Résumé [+] [-]Recent examinations of spirurid nematodes (Spirurida) from deep-sea or coral reef marine fishes off New Caledonia, collected in the years 2006–2009, revealed the presence of the following five species: Ichthyofilaroides novaecaledoniensis (Moravec et Justine, 2009) n. gen., n. comb. (transferred from Ichthyofilaria Yamaguti, 1935) (females) (Guyanemidae) from the deep-sea fish Hoplichthys citrinus (Hoplichthyidae, Scorpaeniformes), Philometra sp. (male fourth-stage larva and mature female) (Philometridae) from Epinephelus maculatus (Serranidae, Perciformes), Ascarophis (Dentiascarophis) adioryx Machida, 1981 (female) (Cystidicolidae) from Sargocentron spiniferum (Holocentridae, Beryciformes), Ascarophis (Ascarophis) nasonis Machida, 1981 (males and females) from Naso lituratus and N. unicornis (Acanthuridae, Perciformes), and Ascarophisnema tridentatum Moravec et Justine, 2010 (female) from Gymnocranius grandoculis (Lethrinidae, Perciformes). Two species, I. novaecaledoniensis and A. nasonis, are redescribed based on light microscopical (LM) and scanning electron microscopical (SEM) examinations, the latter used in these species for the first time. Morphological data on the specimen of A. tridentatum from the new host species are provided. Philometra sp. (from E. maculatus) most probably represents a new gonad-infecting species of this genus. The newly established genus Ichthyofilaroides n. gen. is characterized mainly by the presence of a small buccal capsule and by the number and distribution of cephalic papillae in the female; it is the sixth genus in the Guyanemidae.

Résumé [+] [-]Proctophantastes brayi n. sp. (Digenea: Zoogonidae; Lepidophyllinae) has been found in the intestine of two species of deep-sea fish Polymixia (silver eye fish) near the island of Erromango in Vanuatu at a depth ranging from 720 to 830 in. Specimen whole mounts, histological and scanning electron microscopy preparations showed that P. brayi differs from the five known species of the genus Proctophantastes (P. abyssorum, R gillissi, R glandulosum, P. infundibulum and P nettastomatis) by the following morphological characters: (i) a slit in the anterior part of the oral sucker, (ii) Laurer's canal is absent, (iii) a more extended periatrial gland than the ones in the other species of Proctophantastes, consisting of divided masses of cells and that form a conspicuous multilobated structure which does not have a membrane-bounded sac, (iv) the distal part of the metraterm has vesicle-like processes which we refer to as metratermal sacs, in addition to atrial sacs, (v) a long extension of the glandular cells surrounding the saccular bladder which extends posteriorly to the excretory pore.

Résumé [+] [-]The Thoosidae (Porifera, Demospongiae, Tetractinellida) currently includes the genera Thoosa, Alectona, and Delectona. To this date, molecular data are only available for Alectona. In this study, the phylogenetic affinities of the genera Thoosa and Alectona have been investigated with the species T. mismalolli, T. calpulli, and T. purpurea from the Mexican Pacific using morphology and three molecular loci: the mitochondrial cytochrome oxidase subunit 1 (CO1 mtDNA), 28S rRNA (fragment D2), and 18S rRNA. Morphology and embryology showed that these genera are quite different from the rest of the tetractinellids because larvae of Alectona and Thoosa have unique features in sponges, such as the presence of monaxonic discs in Thoosa and tetraxonic discs in Alectona which disappear in the adult stages. A phylogenetic analysis using selected species from the order Tetractinellida revealed that Thoosa groups with Alectona thus confirming morphological studies. The peculiarities in spiculation and embryology of the Thoosa and Alectona larvae, which are markedly different from species belonging to the suborders Astrophorina and Spirophorina and their distant phylogenetic position (based on three molecular loci), suggest that Thoosidae could be placed in the new suborder Thoosina.

Résumé [+] [-]The siliceous sponges and crinoids from the Chénier Ravine (France, Lower Callovian) are used here as biological markers to characterize the palaeoenvironment of the adjacent and contemporaneous La Voulte Lagerstätte that is remarkable for its unique soft-bodied fauna (e.g. worms, cirrate octopods, vampire squids). Sponges are abundant with dominant hexactinellids (80%) and lithistids (20%). Four lines of fossil evidence, supported by Recent analogues, indicate that this sponge community inhabited deepwater setting under dysphotic or aphotic conditions: (1) the dominance of hexactinellids; (2) the prevalence of cone shaped and erect morphologies that usually characterize Recent bathyal sponges; (3) the close similarities with Recent hexactinellids from the continental slope and; (4) the lack of encrustation by photophilic organisms. Attachments of sponges on hard substrate (e.g. crystalline basement) and their preservation in soft sediments (e.g. muds) indicate heterogeneous bottom conditions. The Chénier fauna also contains small stalked, asymmetric cyrtocrinid crinoids that are known to live on hard substrates in bathyal environments such as the SW Pacific steep seamounts. Convergent palaeoenvironmental clues obtained from both crinoids and siliceous sponges support the notion that the La Voulte area, including the La Voulte Lagerstätte, was situated in the upper part of the bathyal zone near the slope-basin transition with a water depth most probably exceeding 200 m. Supporting evidence from heterogeneous substrates and complex fault systems indicate a depositional environment along the external part of the slope where steep topographies and blocks usually favour the settlement of cyrtocrinid crinoids and hexactinellid sponges. La Voulte may therefore be one of the rare and extremely precious Mesozoic Lagerstätten to have fossilized a deep marine environment.

Cárdenas P. 2020. Surface Microornamentation of Demosponge Sterraster Spicules, Phylogenetic and Paleontological Implications. Frontiers in Marine Science 7. DOI:10.3389/fmars.2020.613610
Résumé [+] [-]Siliceous spicules in demosponges exist in a variety of shapes, some of which look like minute spheres of glass. They are called “sterrasters” when they belong to the Geodiidae family (Tetractinellida order) and “selenasters” when they belong to the Placospongiidae family (Clionaida order). Today, the Geodiidae represent a highly diverse sponge family with more than 340 species, occurring in shallow to deep waters worldwide, except for the Antarctic. The molecular phylogeny of Geodiidae is currently difficult to interpret because we are lacking morphological characters to support most of its clades. To fill this knowledge gap, the surface microornamentations of sterrasters were compared in different genera. Observations with scanning electron microscopy revealed four types of surfaces, which remarkably matched some of the Geodiidae genera: type I characteristic of Geodia, type II characteristic of Pachymatisma, Caminus, and some Erylus; type III characteristic of other Erylus; type IV characteristic of Caminella. Two subtypes were identified in Geodia species: warty vs. smooth rosettes. These different microornamentations were mapped on new Geodiidae COI (Folmer fragment) and 28S (C1–D2) phylogenetic trees. The monophyly of the Geodiidae was once again challenged, thereby suggesting that sterrasters have evolved independently at least three times: in the Geodiinae, in the Erylinae and in Caminella. Surface microornamentations were used to review the fossil record of sterrasters and selenasters through the paleontology literature and examination of fossils. It was concluded that “rhaxes” in the literature may represent mixes of sterrasters and selenasters: while Rhaxella spicules may belong to the Placospongiidae, Rhaxelloides spicules belong to the Geodiidae. The putative Geodiidae fossil genera, Geoditesia, and Geodiopsis, are reallocated to Tetractinellida incertae sedis. Isolated Miocene-Pliocene fossil sterrasters Hataina (Huang, 1967), Silicosphaera (Hughes, 1985) and Conciliaspongia (Robinson and Haslett, 1995) become junior synonyms of Geodia (Lamarck, 1815). Overall, the fossil record suggested that Geodiidae was present at least since the Middle Jurassic (163–166 Mya), while Geodia sterrasters were present since the Santonian/Campanian boundary, Late Cretaceous (83.6 Mya).

Résumé [+] [-]It is shown that the demosponge Corallistes sp. (Tetractinomorpha, Lithistida, Corallistidae) collected in the Coral Sea, contains corallistin A (1), the second example, of a free porphyrin from a living organism. The compound proved to be active against the Kb cell line. In contrast with the geoporphyrins which do not bear any O-atom corallistin A (1) carries two carboxylic groups.

Helvetica chimica Acta 76: 1489-1496
Résumé [+] [-]Reported here are the novel free porphyrins corallistin B, C, D, and E, isolated as methyl esters 2a, 3a, da, and 5a, respectively, from the sponge Corallistes sp. (Lithistida) collected at the basis of the south New Caledonian coral reef. A protocol is also established for formylation of their Ni" complexes, which show a different reactivity pattern toward DMF/POCI, from metal complexes of deuteroporphyrins. Together with corallistin A, previously isolated as the methyl ester la, and the known deuteroporphyrin IX (isolated as 6a) also present in the sponge, the new corallistins, which may be thought to derive from protoporphyrin viu heme, account for an amazing 60% of the EtOH extract from the sponge.

Helvetica Chimica Acta 79: 727-735
Résumé [+] [-]Agelastatin A (l),a n unusual alkaloid ofthe axinellid sponge Agelas dendromorpha from the Coral Sea, can be selectively acetylated (+ 7) or methylated at OH-C(8a) (-+ 4), peracetylated (+ 8) or permethylated at OH-C(8a), NH(5), and NH(6) (+5), or, finally, subjected to C(9)-C(8a) (+ 14) or C(Sb)-C(Sa)B-elirnination (+11-13), in a regiospecific manner or not, depending on the reaction conditions. Under acidic conditions, compound 12 adds H,O or MeOH, regioselectively though not endolexo stereoselectively, giving transoidlcisoid mixtures 1/18 or 4/19, respectively. Similarly 11 or 13 add MeOH to give mixtures (-)-2/20 or 15/16, respectively. Compound 13 also adds AcOH giving mixture 8/17. The intermediate cisoid form obtained on treatment of 21 with H30+ undergoes N(5)-N(6) bridging affording pentacyclic 22 which constitutes a proof for the cisoid configuration. From conformational studies, rules are devised that allow assigning the configuration of these compounds from NMR data. In vitro comparative cytotoxicity assays of these compounds show that for high cytotoxic activity, such as of 1 in vivo, unsubstituted OH-C(8a), H-N(S), H-N(6) moieties are needed in the natural B/D transoid configuration.

Résumé [+] [-]Natural free carboxylic acids from the hadromerid sponge Diacornus levii (Kelly-Borges and Vacelet) were esterified to yield the new cyclic norditerpene peroxides ent-muqubilin benzyl ester (= (aR,3S.6R)-a,6-dimethyl- 6-[(E )-4-methyl-6-(2,6,6-trimethyl-cyclohex-l-en-l-yl)hex-3-enyl]-l,2-dioxan-3-acaectiidc benzyl ester; 6), diacarnoate B methyl ester (= (aS,3S,6R)-a,6-dimethyl-6-{2-[(4aS,8aS)-3.4,4a,5,6,7,8,8a-octahydro-3-oxo- 2,5,5,8a-tetramethylnaphthalen-l-yl)ethyl}-l,2-dioxan-3-acetica cid methyl ester; 9). and deoxydiacarnoate B benzyl ester (= (ccS,3R,6R)-cc,6-dimethyl-6-{2-[(4aS,8aS)-3,4,4a,5,6,7,8,8a-octahydro-2,5,5,8a-tetramethyl-lnaphthalenyl]ethyl]-1,2-dioxan-3-acetiacc id benzyl ester; lo), which were isolated following extensive chromatography. The relative configuration of the peroxideicc-methylacetate moiety of 6, 9, and 10 was directly determined from their NMR spectra. The absolute configurations of the peroxide/cc-methylacetate moiety was deduced from comparative 'H-NMR data of the (S)- and (R)-phenylglycine methyl ester derivatives 7 and 8 as well as 11/13 and 12/14, all obtained from a mixture of the precursors of 3,6, and 10. The absolute configuration at the carbobicyclic moiety of enone 9 and of 10, is identical, as established by chemical interconversion, 9 and 10 belong to the normal labdane series according to empirical CD rules, applied either directly to 9 or to the parent (+)-sclareolide-derived enone 20. In contrast, molar rotation additivity rules suggest the enr-labdane configuration for 9 and 10. The epidioxides 1-3, 6, and 10 proved active in vim against the malaria parasite PIasmodiumfalciparum; especially the previously isolated methyl 3-epinuapapuanoate (2) was active against a chloroquine-resistant strain, and this with a good security index.

Marine natural products : chemical constituents from New Caledonian deep-water species, in Troisième Symposium sur les substances naturelles d'intérêt biologique de la région Pacifique-Asie, Nouméa, CNRS-ORSTOM
Résumé [+] [-]During our ongoing program of searching for new bioactive molecules from new-caledonian marine invertebrates, the opportunities occured recently to examine a "living fossil" crinoid Gymnocrinus richeri, discovered by B. Richer de Forges at 520m depth. In vivo this crinoid is saffron yellow with the stalk darker and tentacles dark yellow-green inside. A few minutes after collecting, outside the water, it turns readily dark-green. The green pigments, extractable with methanol, turned violet on very mild acidification. In this communication the structure of five violet pigments, which constitute a novel group of brominated phenanthroperylenequinones, will be discussed. These pigments have interesting stereochemical features, i.e. the axial chirality generated by the phenanthroperylenequinone system forced into a non planar helical shape. The assignment of the stereochemistry based on CD, NMR data and correlation with natural occuring perylenequinones will he presented. There is also considered the possible relationship between the violet pigments and the native yellow and green ones. A second "living fossil" organism from New Caledonia which we had the opportunity to examine is the starfish species Tremaster novae caledoniae collected at 530m depth off Nouméa. This organism contains a group of unusual steroids in which one hydroxyl group is sulphated, one is acetylated and a third one is esterified with glucose-I-phosphate. The results of the chemical investigation of the sponge Jereicopsis graphidiophora (new genus) and Erylus sp. collected at ca. 500m depth off Nouméa, will he also presented. While the 3B- hydroxy steroids were totally absent, the extracts of J. graphidiophora contain unique 38- hydroxy steroids. L'wo of them combine the unique 38- methoxyl group with a rare secostructure. The polar extracts of Erylus sp. contain two terpenoid oligoglycosides. Sequential analysis of the oligosaccharide portions was achieved by modern 2D-NMR techniques.

Résumé [+] [-]The isolation acd characterization of two novel triterpene glycosides from a sponge of the genus Eryhs, collected at a depth of 500 m in the South of New Caledonia, are described. The structures are characterized by the presence of a branched oligosaccharide chain, composeí1 of three (1) and four (2) D-galactopyranose units, respectively. Analysis of the oligosaccaride structures was achieved by { 'H, 'H} correlation spectroscopy, two-dimensional homonuclear Hartmann-Hahn, and 'H-detected ('H, I3C} one bond (HMQC) and multiple-bond (HMI3C) shift correlation NMR experiments. The novel lanostane derived aglycone features a mre 14-carboxyl grdup and a 24-methylene, 25-methyl side chain.

Résumé [+] [-]The deep-water New Caledonian sponge Cladocroce incurvata contains two ''polyketide'' metabolites. Cladocrocin A [1] appears to be derived from fatty acids with ethyl side chains, thus incorporating butyrate units. Cladocroic acid [2] is a straight chain fatty acid which incorporates a terminal enyne functionality and a cyclopropane ring directly attached to the carboxylic acid function. The structures were elucidated by interpretation of spectral data, and the cis stereochemistry of the cyclopropane ring in cladocroic acid [2] was derived after the synthesis of cis- and trans-2,3-methanohexanoic acid models and nmr spectral comparisons.

Résumé [+] [-]Five novel brominated phenanthroperylenequinone pigments, gymnochromes A-D (1-4) and isogymnochrome D (5), were isolated from the stalked crinoid Gymnocrinus richeri. The structures of the compounds were inferred from their spectra (IR, UV-vis, H-1 and C-13 NMR, FABMS). The presence of both bulky hydroxy groups at positions 10 and 11 and side chains at positions 3 and 4 causes sufficient crowding to force the octacyclic phenanthroperylenequinone system into a nonplanar helical shape. This helicity generates axial chirality in the molecules. The presence of chiral carbon atoms in the side chains gives rise to diastereomers. The absolute configurations of the chiral carbons and the axial chirality of the natural pigments was inferred from CD and NMR data and by correlations made with cercosporin and other naturally occurring perylenequinones. The configurations assigned to the chiral carbons in the side chains of compounds 4 and 5 were confirmed by the results of the application of Horeau's method of kinetic resolution.

Résumé [+] [-]Ten novel polyhydroxylated 9,ll-secosterols, 1-10, have been isolated from the New Caledonian sponge Euryspongiu sp. and their structures elucidated by spectroscopic studies, selcctive acetylation and reduction, leading to the complete assignment of all the NMR signals. Euryspongiols Al-A5 differ in their side chains but have the same 2a,3ß,4a,6ß,11,19 hexahydroxy-9,ll-secocholestane skeleton. Euryspongiols B 1-B5 are the corresponding 3a epimers. Compounds 1-10 are the most highly hydroxylated secosteroids isolated so far, and are the first hydroxylatcd at C4. NaBH4 reduction of the carbonyl group at C-9 of 1 and 2 is stereospecific, producing the heplahydroxylated secosteroids la and 2b with a ß C-9 hydroxyl group. Compounds 1 and 2 have been found to strongly inhibit the release of histaminc from rat mastocysts.

Résumé [+] [-]Reconstructing the phylogeny of sponges (Porifera) is one of the remaining challenges to resolve the metazoan Tree of Life and is a prerequisite for understanding early animal evolution. Molecular phylogenetic analyses for two of the three extant classes of the phylum, Demospongiae and Calcarea, are largely incongruent with traditional classifications, most likely because of a paucity of informative morphological characters and high levels of homoplasy. For the third class, Hexactinellida (glass sponges)-predominantly deep-sea inhabitants with unusual morphology and biology - we present the first molecular phylogeny, along with a cladistic analysis of morphological characters. We collected 18S, 28S, and mitochondrial 16S ribosomal DNA sequences of 34 glass sponge species from 27 genera, 9 families, and 3 orders and conducted partitioned Bayesian analyses using RNA secondary structure-specific substitution models (paired-sites models) for stem regions. Bayes factor comparisons of different paired-sites models against each other and conventional (independent-sites) models revealed a significantly better fit of the former but, contrary to previous predictions, the least parameter-rich of the tested paired-sites models provided the best fit to our data. In contrast to Demospongiae and Calcarea, our rDNA phylogeny agrees well with the traditional classification and a previously proposed phylogenetic system, which we ascribe to a more informative morphology in Hexactinellida. We find high support for a close relationship of glass sponges and Demospongiae sensu stricto, though the latter may be paraphyletic with respect to Hexactinellida. Homoscleromorpha appears to be the sister group of Calcarea. Contrary to most previous findings from rDNA, we recover Porifera as monophyletic, although support for this clade is low under paired-sites models.

Résumé [+] [-]Glass sponges (Class Hexactinellida) are important components of deep-sea ecosystems and are of interest from geological and materials science perspectives. The reconstruction of their phylogeny with molecular data has only recently begun and shows a better agreement with morphology-based systematics than is typical for other sponge groups, likely because of a greater number of informative morphological characters. However, inconsistencies remain that have far-reaching implications for hypotheses about the evolution of their major skeletal construction types (body plans). Furthermore, less than half of all described extant genera have been sampled for molecular systematics, and several taxa important for understanding skeletal evolution are still missing. Increased taxon sampling for molecular phylogenetics of this group is therefore urgently needed. However, due to their remote habitat and often poorly preserved museum material, sequencing all 126 currently recognized extant genera will be difficult to achieve. Utilizing morphological data to incorporate unsequenced taxa into an integrative systematics framework therefore holds great promise, but it is unclear which methodological approach best suits this task.

Résumé [+] [-]The sponge Stelletta sp. (Astrophorida, Stellettidae), collected at - 700 m in the Coral Sea, is shown to contain sterones and sterols of the stigmastane type with a C(24) = C(25) bond for which there is no precedent in the sea. Structure elucidation of the second abundant of these steroids, stigmasta-4,24(25)-dien-3-one((+)-1), is based on 1D and 2D NMR spectra and chemical transformation to acetate (-)-5. Stigmasta-4,24(25)-diene-3,6-dione ((-)-3), present in trace amounts in the sponge, was obtained in sufficient quantity for NMR study by oxidation of the also present, inseparable, and abundant 4:1 mixture of stigmasta-5,24(25)-dien-3-beta-ol (6) and its 5,6-dihydro derivative 7 (Scheme 1). This oxidation also afforded the ketone analogues (+)-8 and (+)-9, which could be separated, thus making structure elucidation possible. The 6-beta-hydroxystigmasta-4,24(25)-dien-3-one ((+)-4), also present in trace amounts in the sponge, was obtained in sufficient amount for NMR study, together with its C(6) epimer (+)-11, by hydroperoxidation of (+)-8 followed by deoxygenation (Scheme 2). The last trace steroid of the sponge, stigmasta-4,6,24(25)-trien-3-one ((-)-2), was structurally elucidated using limited NMR data and comparison with the other stigmastanes. These stigmastanes, as the only steroids of this sponge, are likely to function as stabilizers of its cell walls; their phytosteroid structure, for a sponge which lives in the dark of deep waters, suggest origin through a complex food chain, possibly followed by bioelaboration in the sponge.

Résumé [+] [-]The lithistid sponge Corallistes undulatus, which inhabits the base (- 510 m) of the New Caledonian coral reef, is shown here to contain the pteridines 1-methylpteridine-2,4- dione, already known from another Corallistes, and the new(1'R,2'S)-6-(1',2'-dihydroxypropyl)- 1-methylpteridine-2,4-dione together with the steroids 3ß-hydroxy-24- methylenecholest-5-en-7-one, 7-ALPHA-hydroxysitosterol,7ß -hydroxysitosterol, and 3ß-hydroxystigmast-5-en-7-one, typical of higher terrestrial plants, and the indole derivatives methyl(2E)-3-(indol-3-yl)-2-propenoate, methyl(2E)-3-(6-bromoindol-3-yl)- 2-propenoate, and serotonin. The presence of the same compounds in taxonomically, phyletically, and ecologically unrelated organisms is viewed here as resulting from evolutionary convergence toward adaptive products.

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification. Frontiers in Marine Science 8: 749078. DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

Résumé [+] [-]Aulospongus is revised to contain 10 species (cerebella Dickinson, flabellum Pultizer-Finali, gardineri (Dendy), involutum (Kirkpatrick), monticularis (Ridley & Dendy), novaecaledoniensis sp. nov., samariensis sp. nov., spinosum (Topsent), tubulatus (Bowerbank) and villosa (Thiele)). Other species previously included in Aulospongus are referred to Raspailia (Raspaxilla), most being new combinations. Raspailia (Raspaxilla) and Endectyon (Hemectyon) are also reviewed and some re-illustrated, containing 17 and 1 species, respectively. Aulospongus is contrasted with these genera, differing in having two homologous size categories of rhabdostyles, apparently of common derivation, coring and echinating fibres; plumose skeletal structure persisting throughout choanosomal and peripheral skeletons composed of ascending compressed fibre-bundles with few or no reticulate elements; lacking any differentiation between axial and extra-axial skeletons. Phylogenetic analysis delineates 2 groups of Aulospongus species based primarily on skeletal structure: one group exclusively plumose, the other with rudimentary plumo-reticulate skeletons, with the non-rhabdose raspailiid outgroup predominantly plumo-reticulate or reticulate, with loss of ectosomal specialisation being highly homoplasic and unstable throughout the classification of Raspailiidae. Biogeographic comparisons among rhabdose raspailiids (Aulospongus versus Raspaxilla and Hemectyon) show essential differences in distributions (pan-equatorial versus Pacific rim, respectively).

Résumé [+] [-]Diagnostic morphological characters for the sponge genus Pleroma, relicts from a diverse group of lithistid sponges (Suborder Megamorina: Family Pleromidae) that were once common in the north-western European late Jurassic to the late Cretaceous (c. 140-65 Ma), are reviewed following examination of new collections of known species from northern New Zealand and the south New Caledonian slope. Before this work, only two living species of Pleroma were known, the genus holotype P. turbinatum Sollas from Fiji, and P. menoui Levi & Levi from south New Caledonian seamounts. A new species, P. aotea n. sp., is described from northern New Zealand waters, extending the suite of diagnostic characters to include nodulose megaclone desmas and amphiaster microscleres. Megaclone desmas, indistinguishable from those of P. menoui and P. aotea n. sp., are recorded from the Oamaru Diatomite in southern New Zealand (late Eocene), and the Tutuiri Greensand, Chatham Island (late Palaeocene), respectively. These published and new microfossil discoveries establish a disjunct geographic distribution for Pleroma in New Zealand.

Kelly M. 2007. The Marine Fauna of New Zealand: Porifera: lithistid Demospongiae (Rock Sponges). NIWA Biodiversity Memoir 121: 1-100
Résumé [+] [-]The lithistid Demospongiae fauna of New Zealand has been inventoried from existing and new collections, and is reviewed here and revised where necessary. Most of the 282 specimens examined were recorded from the largest collection of sponges in New Zealand, in the NIWA Invertebrate Collection, Wellington. Significant collections were also examined from the Museum of New Zealand Te Papa Tongarewa. The lithistid Demospongiae (formerly order Lithistida Schmidt, 1870) is represented in the New Zealand region by nine families, 18 genera (one of which is new to science), and 30 species (12 of which are new to science): Theonellidae (1 genus, 1 species), Phymatellidae (3 genera, 6 species), Corallistidae (3 genera, 7 species), Neopeltidae (4 genera, 4 species), Macandrewiidae (1 genus, 1 species), Pleromidae (1 genus, 3 species), Isoraphiniidae (1 genus, 1 species), Scleritodermiidae (3 genera, 5 species), and Azoriciidae (1 genus, 2 species). This work records the first lithistid species, Neoschrammeniella antarctica n. sp., known from polar regions, and provides the first record of the genus Leiodermatium further south than the Philippines. Two additional species of Leiodermatium described here are found only in the west-central Pacific and Micronesian deep waters, but are included for the sake of a complete review of the genus in the Pacific. New species of the previously monospecific phymatellid genera Neoaulaxinia and Neosiphonia are described, and a new corallistid genus, Awhiowhio, is recognised from New Zealand waters. All specimens were dredged from between 80 and 1700 m, but were commonest between 200 and 800 m. With the exception of one specimen from the eastern edge of the Challenger Plateau on New Zealand’s west coast, and a new species from the Ross Sea, Antarctica, all were found north of the southern edge of the Chatham Rise and in New Zealand’s northernmost waters. Known and new species are redescribed from representative New Zealand material and, in some cases, the characters used to define genera and species are redefined and clarified. In particular, ornamentation of the desma skeleton and morphology of the augmenting microscleres are emphasised for distinction at the species level.

Résumé [+] [-]Soft sedimentary ocean floors are inhospitable for sponges except for a few species which provide their own anchors in the form of rods that act as stakes. Of these, the Monorhaphis (Porifera hexactinellida) is remarkable for the size of its single anchoring spicule. It is also quite rare. After the first reported finding by Chun [1] on his 1898-99 Indian Ocean expedition, the only other report would appear to be that by Burton [2] in 1959.

Résumé [+] [-]Nortopsentin D (S), a bis(indo1e) alkaloid unique for bearing a 2-amino-methylimidazole appendage at the central lH-imidazol-5(4H)-one nucleus, was isolated in abundance, besides the putative biogenetic precursor 6 of its appendage, from the deep-water axinellid sponge Dragmacidon sp. Structural elucidation of 5 by NMR and MS methods heavily relied on its N-methyl derivatives 8-11. Unusually for topsentin-type structures, natural 5 and semisynthetic methyl derivatives 8 and 10 proved inactive on KB tumoural cells, while introduction of the last three methyl groups, amazingly led to highly cytotoxic 11.

DOI:10.1093/zoolinnean/zlz017
Résumé [+] [-]Abstract This study reinforces and extends the findings of previous molecular studies showing that there is a close relationship between species assigned to the sponge genera Halicnemia, Higginsia, Paratimea and Stelligera and that the family Heteroxyidae is polyphyletic. The present study has led to the description of one new species of Halicnemia and six new species of Paratimea, the resurrection of Halicnemia gallica and a better understanding of the characters uniting Stelligeridae. A new species of Heteroxya is also described. We demonstrate that many of the taxa assigned to Heteroxyidae are more closely related to other families, and we propose several changes to the classification of Heteroscleromorpha. Desmoxyidae is resurrected from synonymy and transferred to Poecilosclerida; Higginsia anfractuosa is transferred to Hymedesmiidae, and a new genus, Hooperia, is erected for its reception; Higginsia durissima is returned to Bubaris (Bubaridae); Higginsia fragilis is transferred to Spanioplon (Hymedesmiidae); Hemiasterella camelus is transferred to Paratimea; and Raspailia (Parasyringella) australiensis and Ceratopsion axiferum are transferred to Adreus (Hemiasterellidae).

Résumé [+] [-]Abstract Background A basal spicule of the hexactinellid sponge Monorhaphis chuni may reach up to 3 m in length and 10 mm in diameter, an extreme case of large spicule size. Generally, sponge spicules are of scales from micrometers to centimeters. Due to its large size many researchers have described its structure and properties and have proposed it as a model of hexactinellid spicule development. Thorough examination of new material of this basal spicule has revealed numerous inconsistencies between our observations and earlier descriptions. In this work, we present the results of detailed examinations with transmitted light and epifluorescence microscopy, SEM, solid state NMR analysis, FTIR and X-ray analysis and staining of Monorhaphis chuni basal spicules of different sizes, collected from a number of deep sea locations, to better understand its structure and function. Results Three morphologically/structurally different silica layers i.e. plain glassy layer (PG), tuberculate layer (TL) and annular layer (AL), and an axial cylinder (AC) characterize adult spicules. Young, immature spicules display only plain glassy silica layers which dominate the spicule volume. All three layers i.e. PG, TL and AL can substitute for each other along the surface of the spicule, but equally they are superimposed in older parts of the spicules, with AL being the most external and occurring only in the lower part of the spicules and TL being intermediate between AL and PG. The TL, which is composed of several thinner layers, is formed by a progressive folding of its surface but its microstructure is the same as in the PG layer (glassy silica). The AL differs significantly from the PG and TL in being granular and porous in structure. The TL was found to display positive structures (tubercles), not depressions, as earlier suggested. The apparent perforated and non-perforated bands of the AL are an optical artefact. The new layer type that we called the Ripple Mark Layer (RML) was noted, as well as narrow spikes on the AL ridges, both structures not reported earlier. The interface of the TL and AL, where tubercles fit into depressions of the lower surface of the AL, represent tenon and mortise or dovetail joints, making the spicules more stiff/strong and thus less prone to breaking in the lower part. Early stages of the spicule growth are bidirectional, later growth is unidirectional toward the spicule apex. Growth in thickness proceeds by adding new layers. The spicules are composed of well condensed silica, but the outermost AL is characterized by slightly more condensed silica with less water than the rest. Organics permeating the silica are homogeneous and proteinaceous. The external organic net (most probably collagen) enveloping the basal spicule is a structural element that bounds the sponge body together with the spicule, rather than controlling tubercle formation. Growth of various layers may proceed simultaneously in different locations along the spicule and it is sclerosyncytium that controls formation of silica layers. The growth in spicule length is controlled by extension of the top of the axial filament that is not enclosed by silica and is not involved in further silica deposition. No structures that can be related to sclerocytes (as known in Demospongiae) in Monorhaphis were discovered during this study. Conclusions Our studies resulted in a new insight into the structure and growth of the basal Monorhaphis spicules that contradicts earlier results, and permitted us to propose a new model of this spicule’s formation. Due to its unique structure, associated with its function, the basal spicule of Monorhaphis chuni cannot serve as a general model of growth for all hexactinellid spicules.

Résumé [+] [-]Glass sponges (Class Hexactinellida) are described from the Perth Canyon in the eastern Indian Ocean, resulting in 10 genera being recorded, including 11 species, five of which are new to science. In addition, the study resulted in two new records for Australia, Pheronema raphanus and Monorhaphis chuni, and one new record for the Indian Ocean, Walteria flemmingi. A second species of Calyptorete is described over 90 years after the genus was first established with a single species. A significant difference was noted between the condition of sponges collected on the RV Falkor, which used an ROV, and the earlier RV Southern Surveyor expedition, which used sleds and trawls. The ROV collected specimens were in excellent condition, while those from the sleds and trawls tended to be damaged or fragmented.

Résumé [+] [-]Euryplegma auriculare, previously known off the coast of New Zealand, has recently been collected from the vicinity of New Caledonia, Fiji, Wallis and Futuna Islands. The description of spicules, structure and speculation on the origin of this species as well as reinvestigation of the related genera, Tretopleura and Fieldingia, has led to revision of the family Aulocalycidae and modification of its diagnosis. The scope of the family has been restricted to five genera: Euryplegma. Aulocalyx, Rhabdodictyon, Ijimadictyon, and Leioplegma. A new taxon Aulocalycoida, with the same rank as the orders Hexactinosa, Lychniscosa, Lyssacinosa, has been proposed to receive the reorganized family. It is distinguished by an aulocalycoid framework. The order Hexactinosa is thus restricted to include all of its former families except for the family Aulocalycidae. Two genera previously included in the Aulocalycidae, Tretopleura and Fieldingia, are reassigned because of their lack of an aulocalycoid framework. Tretopleura is referred to the hexactinose family Euretidae without a clear closest relative. Fieldingia (sensu stricto), still pooriy known, is provisionally referred to the order Reticulosa, as incertae sedis, and possibly represents the only extant member of that group. It has some similarity to the family Stromatidiidae, but cannot be included in that taxon with the limited information now available. The position of Reticulosa in relation to the more well-known recent Hexactinellida taxa remains unclear.

Résumé [+] [-]Sphinctozoan sponges were major reef-builders in the Permo-Triassic. For a long time, they were considered to be extinct, until a discrete, solitary "living fossil" was found in cryptic reef habitats. A new extant sphinctozoan, with the same colonial morphology and construction capabilities as its fossil counterparts, has been discovered in bathyal environments off from New Caledonia. A significant difference from modern scleractinian reff-builders is the particularly low growth rate: the basal part of a 10 cm thick contruction is approximately 700 years old.

Résumé [+] [-]Discorhabdella pseudaster n. sp. is an incrusting sponge from the upper bathyal zone of the ‘Banc du Geyser’, north of Madagascar, Mozambique Channel. This new species is described only from a single specimen but it is remarkable by the presence of spicules similar to euasters, a type of microsclere unknown in Poecilosclerida. These spicules are in fact a new example of homoplasy, being derivatives of the typical Discorhabdella pseudoastrose acanthostyles, which are here reduced to the aster-like tyles. The isochelae with a large lamella on the shaft are also quite unique in Poeciloclerida.

Résumé [+] [-]Four new genera, Eoatria, Poratria, Microporatria, and Multatria, are described, joining the previously described genus Bryozobia in the subfamily Bryozobiinae, a subfamily now represented by ten species of which four are new to science. Evidence is presented that Bryozobia is intimately associated with sponges, rather than bryozoans as Ross and Newman (1996) inferred from the intimate proximity of barnacle and bryozoan calcareous remnants. The four new genera are also associated with burrowing or encrusting sponges and generally possess secondary as well as primary radial atria between their basis and the substratum. The primary atria are aligned with portals in the suture between the wall plates and the basis whereas secondary atria can be parietal as well as interparietal. Eoatria has weakly developed, solid atria aligned with portals in the suture between the wall plates and the basis, but the atrial “ceilings” remain solid. The other genera have atria with pores or slits that develop from portals in the suture between the basis and the wall during ontogeny. All species of Bryozobiinae maintain contact with the substratum via calcareous outgrowths of the basis and/or wall, and their sponge symbiont grows from beneath and around them during ontogeny, nearly encasing them in sponge tissue. The basal atria enable the sponge to grow out from beneath the barnacle, and the evidence suggests chemical mediation by the barnacles induces the sponges to grow up around them, as it does in coral-inhabiting barnacles (Ross and Newman, 2000). This symbiosis apparently also provides the barnacles with a habitat relatively free of spatial competitors as well as protection from various predators, and allows the barnacles to thrive where other encrusting organisms cannot. While the porous, atriate bases found in some of the coralinhabiting barnacles (Pyrgomatidae) are likely convergent, monophyly cannot presently be completely ruled out. The diagnosis of the sponge-inhabiting members of the subfamily Acastinae is amended to include only those species lacking atria that are completely embedded in host tissues: that is, having no basal contact with any other substratum.

Résumé [+] [-]The silica skeleton of the deep-sea sponge Euplectella aspergillum was recently shown to be structured over at least six levels of hierarchy with a clear mechanical functionality. In particular, the skeleton is built of laminated spicules that consist, of alternating layers of silica and organic material. In the present work, we investigated the micromechanical properties of the composite material in spicules of Euplectella aspergillum and the giant anchor spicule of Monorhaphis chuni. Organic layers were visualized by backscattered electron imaging in the environmental scanning electron microscope. Raman spectroscopic imaging showed that the organic layers are protein-rich and that there is an OH-enrichment in silica near the central organic filament of the spicule. Small-angle x-ray scattering revealed the presence of nanospheres with a diameter of only 2.8 nm as the basic units of silica. Nanoindentation showed a considerably reduced stiffness of the spicule silica compared to technical quartz glass with different degrees of hydration. Moreover, stiffness and hardness were shown to oscillate as a result of the laminate structure of the spicules. In summary, biogenic silica from deep-sea sponges has reduced stiffness but an architecture providing substantial toughening over that of technical glass, both by structuring at the nanometer and at the micrometer level.

Résumé [+] [-]A collection of Pontoniinae associated with ascidians is studied. This collection comprises species belonging to the genera Ascidonia Fransen, 2002; Dactylonia Fransen, 2002; Odontonia Fransen, 2002; Rostronia Fransen, 2002; Pseudopontonia Bruce, 1992; and Periclimenaeus Borradaile, 1915. Two species are described as new to science. Odontonia maldivensis n. sp. can be distinguished from its congeners by the following characters: 1) the absence of a ventral subdistal tooth of the rostrum; 2) the unguis of the ambulatory pereiopods having a distal region with about 25 transverse rows of serrate scales; 3) the absence of a distal accessory tooth on the corpus of the dactylus; and 4) the dactyli of the second chelipeds having a pile of long simple setae on the dorsal surface. Periclimenaeus orbitocarinatus n. sp. is characterized by a pronounced postorbital carina lacking in its congeners. New hosts are recorded for almost all species and their known geographical distribution is extended. A key to species of Periclimenaeus associated with compound ascidians is provided.

Résumé [+] [-]Two cases of human intoxication causes by the lyophilized powder of Lissoclinum bistratum sluiter. A New Caledonian ascidian are reported. The symptoms observed were caused by a substance designated bistramide A (C40H68N2O8) of hitherto unknown chemical structure. Preliminary toxocological investigations indicate that bistramide A may effect the central nervous system leading to paresthesia ans loss of muscle ton. A progressive decrease in cardiac rythm was also observed in animal. Bistramide A (1,4X10M) did not alter the resting potential of frog heart and skeletal muscle but reduced the amplitude and duration of cardiac action potential ans prolonged the interval between actions potentials, Bistramide A also has a marked cytotoxic effect on cancer cells KB and on normal endothelial cells. Howewer, it has not, been possible to relate the cytotoxic property to the symptoms of intoxication. Bistramidea may originate from the urochordate itself or from symbiotic algae

Résumé [+] [-]Detailed study of the Monniot collection of copepods belonging to the family Notodelphyidae has revealed an extraordinary diversity of novel taxa. With rare exceptions notodelphyids live in association with ascidians and the Monniot collection was built up over several decades of field collecting and taxonomic research on the ascidian hosts by Drs Claude & Françoise Monniot (MNHN, Paris). This paper describes a total of 178 new species of notodelphyids from ascidian hosts and 37 new genera are established: Bathynotodelphys gen.nov., Pronotodelphys gen. nov., Ooishillgia gen. nov., Nobinerilla gen. nov., Notopygus gen. nov., Chelipygus gen. nov., Sympygus gen. nov., Vaoda gen. nov., Gosbia gen. nov., Pentachaetus gen. nov., Diceratus gen. nov., Prodoroixys gen. nov., Notoixys gen. nov., Borixys gen. nov., Cystixys gen. nov., Ammonixys gen. nov., Ctenixys gen. nov., Ademoixys gen. nov., Gallincola gen. nov., Scoliosoma gen. nov., Contoura gen. nov., Unimeria gen. nov., Mecodelphys gen. nov., Tubipedia gen. nov., Procampodelphys gen. nov., Janius gen. nov., Campodelphys gen. nov., Hamaticoxa gen. nov., Adrodelphys gen. nov., Phyllodelphys gen. nov., Lissodelphys gen. nov., Nodoscarus gen. nov., Diblastus gen. nov., Chilodelphys gen. nov., Scaridelphys gen. nov., Socotradelphys gen. nov., and Aplodelphys gen. nov. Prior to this study the Notodelphyidae comprised exactly 200 valid species classified in 46 genera, a mean species richness of 4.3 species per genus. After the addition of the new taxa described here, the family now comprises 378 species in 83 genera, a mean species richness of 4.6 species per genus. Generic diagnoses are provided for all genera represented in the collection and the availability of a wider range of taxa has allowed certain generic boundaries to be better defined, resulting in transfers of species between genera and the recognition of 16 new combinations. A further 51 existing species are also reported, and brief supplementary notes or full redescriptions are provided as appropriate.

Résumé [+] [-]A survey of the bathyal and abyssal area around New Caledonia began in the South-West Pacific Ocean with some recent cruises of french research vessels. The ascidian fauna appears especially diverse, with 58 species of which 31 are new. The species described here belong to almost all genera known throughout the world showing deep-sea adaptations. The 5 main types of trophic adaptation defined for deep-sea tunicates are represented. Around New Caledonia the species having the most elaborate adaptations are more numerous than in the Antarctic, Atlantic or Indian Oceans. Some of the species may possibly be intermediates between shallow water and deep-sea genera. Some genera previously known by a small number of species are here very diverse, and provide the opportunity to discuss their affinities. This applies to the genera Pharyngodictyon (Aplousobranchia), Simla (Octacnemidae), Bathyoncus and Fungulus (Stolidobranchiata). A new interpretation of Corynascidia and Pterygascidia is proposed. With the discovery of 3 new species in New Caledonia, some evolutionary stages of the genus Molguloides (Molgulidae) may now be discussed in terms of branchial structure. A tabular key of the 13 species of this genus is presented. The bathymetric distribution is compared here and in other oceans. The species showing morphological adaptations to the deep-sea live at higher levels in the New Caledonia area than in other oceanic basins. However the presence of deep-sea forms in relatively high levels has been established in other tropical areas (Indonesia, Philippines, Comores). The higher temperature of the water at this depth in low latitudes may have less influence on the ascidian ecology than the seasonal variations occurring in temperate and cold areas at equivalent depths. The affinities of the New Caledonian deep-sea ascidians vary with the families and the kind of adaptations but they are most closely related to the antiboreal fauna of temperate and cold areas. There is no relationship with the shallow water fauna. For the Polyclinidae, with the greatest diversity, relations are established with New Zealand and the subantarctic areas. The deep-sea phlebobranchs are principally known from the southern hemisphere. New Caledonia has the largest number of Octacnemidae species wordwide. The Styelidae dominate in the deep Atlantic but are poorly represented here. The Pyuridae appear to have expanded from both Austral and Indomalayan areas. The majority of the deep-sea species of Molguloides live in the southern hemisphere and all the shallow-water species are Austral ; the genus is particularly diverse around New Caledonia.

Résumé [+] [-]The deep marine bottoms around New Caledonia have been explored for forty years. The Kanacono (2016) and Kanadeep (2019) campaigns organized jointly by the Muséum national d’Histoire naturelle (MNHN) and the Institut de Recherche pour le Développement (IRD) are the complement of this investigation. They are a part of the program “La Planète Revisitée” in New Caledonia. Among the deep sea benthos twenty two ascidian species were collected and three represent new species showing the characteristic adaptations to an abyssal life. The high diversity of the tropical deep sea benthos is enhanced by these new results. No relations are found between littoral ascidians and forms living in the bathyal or abyssal areas.

Résumé [+] [-]Impact of geochemical environment on metal bioaccumulation in deep-sea ascidians (Protochordates, Tunicates). The amount of Al, V, Mn, Ni and Cu in blood cells of the deep-sea ascidians genus Culeolus, performed by microanalysis, varies according to the geochemistry of the site and the taxonomic position. In Atlantic and Pacific ascidians inhabiting abyssal plains, the cells do not exhibit peculiar accumulations. They store Mn, Ni and Cu in the polymetallic nodule fields of Indian Ocean, Al in the East Pacific hydrothermal station. On the other hand, V storage should depend on individual or taxonomic peculiarities. In the absence of endocytosis, the Culeolus species constitute biological indicators of elements available in a dissolved state or incorporated in food.

Most of the collection’s species are described and figured, their color in life is illustrated by 112 underwater photographs; among them 48 are new species representing a fourth of the material collected. This demonstrates how incomplete the knowledge of the ascidian diversity in this part of the world remains. Moreover, very small or inconspicuous species were seldom collected, as compared to the highly coloured and large forms. Many other immature specimens were also collected but their precise identification was not possible. Almost all littoral families are represented with the exception of the Molgulidae which are more characteristic of soft sediments, a biotope which was not investigated. Among the very diversified genera, the colonial forms largely dominate, including not only all the Aplousobranchia genera but also some Phlebobranchia and Stolidobranchia. Very often only one specimen was available, so a detailed biogeographical distribution cannot be given, and no island endemism can be defined

Monniot F. & Monniot C. 2003. Ascidies de la pente externe et bathyales de l’ouest Pacifique. Zoosystema 25(4): 681-749
Résumé [+] [-]The specimens collected during several recent oceanographic cruises in the tropical western Pacific, sponsored jointly by the MNHN and the IRD, consist of 53 ascidian species, and among them 16 new species. For others, the geographic distribution is increased in the western Pacific. The remarkably high diversity of these organisms between 50 and 1000 m in this part of the world is demonstrated. In all oceans at these depths the ascidian fauna is dominated by solitary organisms, whereas along the littoral fringe the majority of ascidian species are colonial. This systematic pattern is likely to be influenced by substrate: hard nearshore and soft offshore. In this study, among the new species, the solitary ascidians largely dominate, especially well represented by stolidobranchs with eight Styelidae of four genera, four Pyuridae with also four genera, and one Molgulidae. However the originality of this deep fauna is enhanced by the presence, in the typical Octacnemidae family, of a new genus Myopegma n. gen. with a very small species M. melanesium n. gen., n. sp. which has a very peculiar musculature justifying a new taxon.

Monniot F. 2012. Some ascidians from the southern coast of Madagascar collected during the “AtimoVatae” survey. Zootaxa 3197: 1-42
Résumé [+] [-]Surveys of littoral invertebrates along the southern coast of Madagascar have produced the first study of ascidians in this part of the Indian Ocean. Collections were made by SCUBA divers in May and June 2010 down to 25m depth. This region is considered the southern limit for coral reefs but remains diverse biologically. Upwellings and an abundant plankton community particularly favour the abundance of ascidians in this area. Of the 39 species of non-didemnid species described here, eight are new. Ten species are common to South Africa. Other species were for the most part already known from the Mozambique Channel and a few have also been recorded in the western Pacific (either cosmopolitan or introduced).

Résumé [+] [-]Four deep-sea ascidian species collected during the KAVIENG 2014 expedition in Papua New Guinea are described, including additional characteristics not reported previously. Fimbrora calsubia is classified within the family Ascidiidae, Dicopia fimbriata and Octacnemus bythius within Octacnemidae, and Culeolus recumbens within Pyuridae. Anatomical observations confirmed previous descriptions for these four species collected elsewhere. Here, we describe additional morphological features for these species and provide the first barcode DNA sequences (based on a fragment of the mitochondrial gene Cytochrome Oxidase I) for D. fimbriata and C. recumbens.

Résumé [+] [-]The effects of Bistramide A, a new toxin isolated from the Urochordate Lissoclinum bistratum Sluiter have been studied on the mechanical activity of frog heart atrial muscle preparations. The peak tension of isolated trabeculae was sensitlve to nanomolar concentrations of Bistramide A. Lineweaver-Burk relationships suggest that Bistramide A competes with Ca for a common site. In voltage-clamped trabeculae, the toxin inhibited both the cadmium-sensitive Ca current and the phasic component of the tension with a dissociation constant of 3.3 fl and a stoichiometry of 2. Bistramide A decreased the sometric tension of skinned fibres in a dose-dependent manner with a dissociation constant of 400 nM and a stoichiometry of 2. The toxin reduced the maximum Ca activated force and decreased the sensitivity of the contractile proteins to Ca. The data suggest that Bistramide A decreases the Ca-sensitivity of contractile proteins prior to blocking the Ca current.

Résumé [+] [-]The structure and absolute configuration (3R, 17R) of the indole alkaloid arborescidine C were determined by x-ray diffraction. The six-membered ring assumes a half-chair conformation and the seven-membered ring has a twist-like conformation. The crystal packing is characterized by intermolecular hydrogen-bonding between the hydroxyl group and nitrogen atom N4 which leads to the formation of infinite chains of molecules along the a-axis of the crystal. The absolute configurations of two related indole alkaloids, arborescidine B and arborescidine D are inferred from the experimentally determined configuration of arborescidin C molecule. A comparison of the present structure with that of a related indole alkaloid akagerine showed significant conformational and configurational differences.

Résumé [+] [-]The Stomatopoda of the Marquesas Archipelago are reported, based principally on the collection of MUROSTOM 9. Prior to this study, 10 species of stomatopod were known from the Marquesas. Fourteen species are reported of which nine are new records for the Marquesas, and seven are new records for French Polynesia. Nineteen species of stomatopod are now known from the Marquesas. Additionally, 37 species of stomatopod are now known for French Polynesia. Several records represent important range extensions and the most important is that of Neoanchisquilla tuberculata Ahyong, 1998, previously known only from the western Indian Ocean. Moreover, the present series of N. tuberculata includes late pelagic larvae through to adults. Two new species are described: Gonodactyloideus tricarinatus n. sp., and Acanthosquilla crosnieri n. sp. G. tricrinatus n. sp. is the second species in the genus to be described and differs from its congener in having three instead of five mid-dorsal carinae on the telson. Acanthosquilla crosnieri n. sp. differs from its congeners in having two fixed spines adjacent to the articulations of the uropodal endopod. A checklist of the stomatopods known from French Polynesia is provided.

Ahyong S.T. 2005. Phylogenetic analysis of the Squilloidea (Crustacea: Stomatopoda). Invertebrate Systematics 19: 189-208
Résumé [+] [-]Squilloidea is the most speciose of the stomatopod superfamilies and comprises more than 40 genera. Until 2001, three families were recognised: two extant (Harpiosquillidae, Squillidae) and one extinct (Ursquillidae). Recent studies, however, suggested that Harpiosquillidae is nested among other squillids and was thus synonymised with Squillidae. Interrelationships of all squilloid genera are studied by cladistic analysis based on somatic morphology. Results are used to assess the familial classification and investigate the 'shape' of squilloid evolution. The phylogeny of the squilloids shows general trends in the armature of the raptorial claw, increased dorsal carination, a tendency for bilobation of the lateral processes of the exposed thoracic somites, and a change in telson shape from trianguloid with movable submedian teeth, to quadriform with fixed submedian teeth. Harpiosquilla Holthuis, 1964 is deeply nested among other squillid genera, supporting the recent synonymy of the Squillidae and Harpiosquillidae. Characters of the late Cretaceous Ursquillidae show that it is highly derived and is therefore synonymised with Squillidae. Although the antiquity of Ursquilla Hof, 1998 does not show it to be a basal or stem-lineage squilloid, it does show that the squilloids had already undergone significant diversification by the end of the Cretaceous. Species of most squilloid genera are regionally restricted, either to the Indo-west Pacific or Atlanto-east Pacific. Only Alima Leach, 1818, Cloridopsis Manning 1968b, and Pontiosquilla Manning, 1995 are represented in both regions.

Résumé [+] [-]Deep-sea blind lobsters (Polychelidae) from Fiji, Tonga, the Solomon Islands, and Austral Islands are studied. We report the fi rst records of Polychelidae from Tonga, the Solomon and Austral islands, and the fi rst records from Fiji since the Challenger expedition in 1874. Fourteen species in two genera are reported: two species of Pentacheles Bate, 1878 and 12 species of Polycheles Heller, 1862. Polycheles alis n. sp., from the Austral Islands, closely resembles P. ceratus (Alcock, 1894) from Indonesia and the Andaman Sea. Th e new species diff ers from P. ceratus chiefl y in having a small and blunt instead of massive, sharp, antrorse spine on the fi fth abdominal tergite. Polycheles martini Ahyong & Brown, 2002, previously known only from Australia, is reported from Tonga.

Résumé [+] [-]A new genus and species of deepwater lobster of the family Nephropidae, Dinochelus ausubeli n. gen., n. sp., is described from the Philippine Sea off the island of Luzon. The new genus and species is most closely related to species of Thaumastocheles and Thaumastochelopsis, sharing the distinctive, strongly dimorphic chelipeds, and shares features of both genera. Most notably, D. ausubeli n. gen., n. sp. shares movable well-developed eyestalks with species of Thaumastochelopsis (versus highly reduced and fixed eyestalks in species of Thaumastocheles), and similar branchial formula and uropod structure with Thaumastocheles. Dinochelus n. gen. differs from species of Thaumastocheles and Thaumastochelopsis (as well as all other clawed lobsters) in having an inverted, T-shaped epistome. Phylogenetic analysis of 12S rRNA sequences indicated that Dinochelus n. gen. is sister to a Thaumastocheles + Thaumastochelopsis clade. The new species is named after Jesse Ausubel at the occasion of the 10-year synthesis of the Census of Marine Life.

Résumé [+] [-]The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004-2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus mina x sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus brucei Tavares, 1991, and Xeinostoma sakaii Tavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweae Tavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp. nov., is also reported, and is most similar to C. curvirostris Sakai, 1965, from Japan. Crown Copyright 2011 Published by Elsevier GmbH.

Résumé [+] [-]Cymonomid crabs are small cryptic deep-water brachyurans occurring worldwide. Six species have been reported from East Asia: one from both Taiwan and Japan (C. andamanicus Alcock, 1905) and five from Japan only (C. curvirostris Sakai, 1965, C. japonicus Balss, 1922, C. sagamiensis Sakai, 1983, C. soela Ahyong and Brown, 2003, C. umitakae Takeda, 1981). Cymonomus curvirostris, C. japonicus, C. sagamiensis and C. umitakae were described from Japanese waters, but C. andamanicus and C. soela have much more distant type localities - the Andaman Sea and southeastern Australia, respectively. We review all previous records of Cymonomus from East Asia, describe two new species, and clarify the status of records of C. andamanicus and C. soela from the region. Records of C. andamanicus and C. soela from East Asia are referable to two new species occurring in both Taiwan and Japan. The identities of C. japonicus and C. sagamiensis are fixed by neotype selection; C. sagamiensis is made a junior objective synonym of C. umitakae. Six species of Cymonomus are now recorded from Japan, of which two also occur off Taiwan. We also report on cymonomids collected by Taiwanese research vessels in the South China Sea (Dongsha and Macclesfield Bank) of which four species were collected, including C. hakuhoae Takeda and Moosa, 1990, not previously found in Japan or Taiwan. A key to the species of Cymonomus from East Asia and the South China Sea is included.

Résumé [+] [-]The stomatopods from the Austral and Gambier Islands, southern French Polynesia, collected primarily by the BENTHAUS Expedition (2002) are reported herein. Prior to the present study, only one species of stomatopod, Bathysquilla microps (Manning, 1961), was known from the Austral Islands and two from the Gambier Islands, Gonodactylus chiragra (Fabricius, 1781) and Pseudosquilla ciliata (Fabricius, 1787). Seven of nine species in the present collection are reported for the first time from the area, of which Gonodactylellus rubriguttatus (Erdmann & Manning, 1998) and Odontodactylus hawaiiensis Manning, 1967, are reported for the first time from French Polynesia. The series of specimens of G. rubriguttatus includes the largest known of the species, which also shows significantly longer accessory median carinae of the telson than previously reported. Owing to previous taxonomic instability in Chorisquilla excavata (Miers, 1880), the type species of its genus, it is redescribed based on type and other material.

Résumé [+] [-]The Stomatopoda of India is comparatively well studied, with 79 species recorded to date. We herein report on a series of stomatopods collected by commercial fishing trawlers from localities on the southwest and southeastern coasts of India. The present series includes 17 species of stomatopods collected as trawl bycatch; seven are the first Indian records: Lysiosquillina lisa Ahyong & Randall, 2001, Odontodactylus cultrifer (White, 1951), O. japonicus (De Haan, 1844), Faughnia formosae Manning & Chan, 1997, Busquilla plantei Manning, 1978, Carinosquilla spinosa Ahyong & Naiyanetr, 2002, and Quollastria kapala Ahyong, 2001. Faughnia formosae is the first member of the superfamily Parasquilloidea to be recorded from India. We also show that Acanthosquilla dighaensis Ghosh, 1998, is a junior synonym of Bigelowina phalangium (Fabricius, 1798), described from Bombay but widespread in Indian waters.

Résumé [+] [-]Although King Crabs (Lithodidae) have been long known from the western Pacific, to date, none has been recorded from Papua New Guinea. Lithodid crabs are reported for the first time from Papua New Guinea, based on deep-water specimens collected by BIOPAPUA 2010 in the Bismarck Sea. Four species in two genera are reported herein: Neolithodes sp. (based on a badly damaged juvenile specimen), Paralomis haigae Eldredge, 1976, and two new species, Paralomis alis n. sp. and P. papua n. sp. Paralomis alis is most similar to P. histrix (de Haan, 1844) from Japan and two similarly spiny species from Australia and New Zealand, but is distinguished chiefly by differences in carapace ornamentation. Paralomis papua n. sp. appears to be closest to P. ceres Macpherson, 1989, from the western Indian Ocean, in carapace shape and ornamentation, but is readily separated by carapace proportions and pereopodal ornamentation.

Redescription of the hermit crab Diogenes pugilator (Decapoda: Anomura) reveals the existence of a species complex in the Atlanto-Mediterranean transition zone, resulting in the resurrection of D. curvimanus and the description of a new species. Zoological Journal of the Linnean Society: zlab093. DOI:10.1093/zoolinnean/zlab093
Résumé [+] [-]Abstract Examination of material from the coasts of the Iberian Peninsula and nearby areas has revealed that more than one species is mixed under the name for the common diogenid hermit crab, Diogenes pugilator. In this study, three species are recognized, primarily on the basis of a combination of morphological characters and live colour patterns. Diogenes pugilator is redescribed on the basis of a neotype selected from near the supposed type locality, as well as specimens from other localities. Diogenes curvimanus is resurrected and the name attributed to a second species, whereas a third morphotype is described as a new species, Diogenes armatus sp. nov.. The last two species are also fully described and differentiating characters among the three species are discussed. Newly generated sequences from two mitochondrial genes and one nuclear gene, and comparative analyses with other available DNA sequences for the genus, are also included. The corresponding molecular phylogenies support the recognition of the three species and suggest the presence of additional unknown species in the D. pugilator species complex. All previous records of D. pugilator should be revised in the light of these new findings. Finally, a comprehensive identification key to the eastern Atlantic and western Mediterranean species of Diogenes is also provided.

Résumé [+] [-]Patagurus rex gen. et sp. nov., a deep-water pagurid hermit crab, is described and illustrated based on a single specimen dredged from 400 m off Moorea, Society Islands, French Polynesia. Patagurus is characterized by a subtriangular, vaulted, calcified carapace, with large, wing-like lateral processes, and is closely related to two other atypical pagurid genera, Porcellanopagurus Filhol, 1885 and Solitariopagurus Turkay, 1986. The broad, fully calcified carapace, calcified branchiostegites, as well as broad and rigidly articulated thoracic sternites make this remarkable animal one of the most crab-like hermit crabs. Patagurus rex carries small bivalve shells to protect its greatly reduced pleon. Carcinization pathways among asymmetrical hermit crabs and other anomurans are briefly reviewed and discussed.

Anker A. 2013. Notes on two rare and little-known Indo-Pacific snapping shrimps, Alpheus percyi Coutière, 1908 and A. pseudopugnax (Banner, 1953) (Decapoda, Alpheidae). Zootaxa 3722(2): 267. DOI:10.11646/zootaxa.3722.2.8
Résumé [+] [-]Two uncommon, morphologically similar snapping shrimps, Alpheus percyi Coutiere, 1908 and A. pseudopugnax (Banner, 1953), are reported from various localities across the Indo-West and Central Pacific. Both species are re-diagnosed based on type specimens and recently collected material; a lectotype is designated for A. percyi. The range of A. pseudopugnax, previously known only from the type locality in Hawaii, is extended considerably to French Polynesia and Reunion Island in the western Indian Ocean. Both A. percyi and A. pseudopugnax present a significant variation in the postrostral region of the carapace, making identification of specimens based solely on morphology rather difficult. In the field, however, the two species can be easily separated by their diagnostic and very striking colour patterns. Colour patterns also suggest that A. percyi may be more closely related to the species of the A. gracilipes Stimpson, 1860 complex than to A. pseudopugnax.

Résumé [+] [-]Parabetaeus acanthus sp. nov. is described based on two specimens from Thuwal, Saudi Arabia, and Madang, Papua New Guinea. The new species is unique within the genus in possessing an anteriorly directed, spine-like tooth on the mid-dorsal line of the carapace, posterior to base of the eyes, and in the stylocerite not reaching the mid-length of the first article of the antennular peduncle. The chelipeds of P. acanthus sp. nov. are variable in size and proportions, as well as in the armature on the finger cutting edges. This cheliped polymorphism appears to be typical to all species of the genus.

Résumé [+] [-]Alpheus leptochiroides De Man, 1909, a poorly-known species originally described from the Kai Islands in eastern Indonesia, is reported from Kavieng, eastern Papua New Guinea, representing only the second record of this snapping shrimp and slightly extending its distribution range into the tropical western Pacific. The original description was based on a relatively young specimen, whereas the Kavieng specimen is clearly an adult male. Most importantly, several rather important characters of the species were omitted and/or not illustrated by De Man, including the unique and diagnostic rounded cuticular expansions on several areas of the third maxilliped, not present in any other alpheid shrimp. Therefore, a full redescription of the species is provided, with new detailed illustrations.

Résumé [+] [-]Three species of the alpheid shrimp genus Salmoneus Holthuis, 1955 associated with burrows of other decapod crustaceans are reported from various Indo-West Pacific localities. Salmoneus venustus sp. nov. is described based on material collected at two distant localities, Nha Trang Bay, southern Vietnam, the type locality of the new species, and the Yiti-Sifah region east of Muscat, northern Oman. Both specimens were collected with the aid of a suction pump applied to burrow entrances or mounds in muddy sand; the holotype was possibly associated with burrows of the callianassid ghost shrimp, Glypturus sp. Salmoneus venustus sp. nov. shares many characteristics with S. latirostris (Coutière, 1897), including the red banding of the pleon, but can be distinguished from S. latirostris and all other species of the genus by a unique combination of morphological characters. The large-sized Salmoneus brucei Komai, 2009 is reported from Sumba, central Indonesia, representing a significant southward extension of the species’ previously known distribution range and the first record since its original description. The callianassid ghost shrimp Lepidophthalmus cf. rosae (Nobili, 1904) is recorded as a new host of S. brucei. Finally, Salmoneus colinorum De Grave, 2004, associated with burrows of larger snapping shrimps from the Alpheus malabaricus Fabricius, 1798 species complex, is reported for the first time from Madang, Papua New Guinea, representing an eastward extension of the species’ previously known distribution range.

Zootaxa 4646(1): 87-100. DOI:10.11646/zootaxa.4646.1.5
Résumé [+] [-]The alpheid shrimp Nennalpheus Banner & Banner, 1981, hitherto known only from a few records in the tropical western Pacific, is recorded for the first time from the tropical eastern Atlantic, as well as from the Indian Ocean. Nennalpheus gabonensis sp. nov. is described based on a single but complete male specimen collected in mediocre visibility conditions at 11 m depth on a rocky reef north of Libreville, Gabon. The new species presents a substantial number of morphological differences from the two other species of Nennalpheus, especially in the armature of the cheliped fingers. The previously known distribution range of Nennalpheus sibogae (De Man, 1910), the type species of the genus, is extended significantly to include the Central Pacific (Hawaiian Archipelago) and the Indian Ocean (Glorioso Islands in the Scattered Islands group, and Mayotte Island in the Comoro Archipelago). In addition, new illustrations of N. sibogae are provided, including the previously not figured mouthparts and high-quality, contrasting background colour photographs. Field observations indicate that Nennalpheus is able to produce a weak snapping sound by rapidly closing one or both chelipeds, a previously suspected, but never observed behaviour.

Résumé [+] [-]Two new deep-water species of the snapping shrimp genus Alpheus Fabricius, 1798 are described based on the material collected by the expeditions BIOPAPUA, BOA1 and MIRIKY, organised by the Muséum National d’Histoire Naturelle in Paris. Alpheus alaincrosnieri n. sp. from the A. brevirostris (Olivier, 1811) group is described based on material dredged at depths of 198–408 m near the coasts of Papua New Guinea, Vanuatu and Madagascar. This species also occurs in the Philippines, based on morphological characters of a mutilated specimen from Masbate reported by Chace (1988). Alpheus alaincrosnieri n. sp. is unique within the A. brevirostris group, in having small orbital teeth. In most other features, A. alaincrosnieri n. sp. is morphologically closest to A. kagoshimanus Hayashi & Nagata, 2000, A. longipalma Komai & Ohtomi, 2018, A. macroskeles Alcock & Anderson, 1894, A. nonalter Kensley, 1969 and A. acutocarinatus De Man, 1909. Alpheus vanuatu n. sp. is described based on several specimens dredged at depths of 231–331 m off Espirito Santo, Vanuatu. This species most likely represents a deep-water member of the newly defined A. paracrinitus species group, sharing most morphological characters with A. tenuipes De Man, 1910 and A. labis Banner & Banner, 1982.

Résumé [+] [-]A new alpheid shrimp genus, Crosnierocaris gen. nov., is established for Crosnierocaris athanasoides sp. nov., a very peculiar shrimp possibly associated with decomposing sea grass accumulations in deeper water. The type series of C. athanasoides sp. nov. was collected in the Mozambique Channel, north of Grande Glorieuse Island, at a depth of 240–255 m. The new genus presents a unique combination of morphological features, including the very long, slender rostrum armed with a subdistal ventral tooth; the pterygostomial angle projecting as a strong sharp tooth; the third to fifth pleura with their distoventral margins armed with two to four small teeth, a unique feature within the Alpheidae; the sixth pleuron with an articulated plate; the eyes largely exposed dorsally and laterally; the first pereiopods (chelipeds) feebly enlarged in both sexes, stouter but shorter than walking legs; the first pereiopod carpus with rows of short serrulate setae on its mesial surface; the second pereiopod carpus with five subdivisions; the third to fifth pereiopods with meri armed with stout cuspidate setae; the uropodal diaeresis with a strongly dentate lateral portion; and the complete gill-exopod formula, with mastigobranchs on coxae of the third maxilliped and first to fourth pereiopods. Within alpheid shrimps, the rostrum of C. athanasoides sp. nov. is one of the longest relative to the total body length, often reaching half of the carapace length. The phylogenetic position of Crosnierocaris gen. nov. within the Alpheidae remains to be determined, but based on its morphological characters, the new genus appears to be closest to Athanas Leach, 1814, especially in the configuration of the frontal area of the carapace, and Potamalpheops Powell, 1979, for instance, in the armature of the uropodal diaeresis and walking legs, as well as the presence of setal rows on the cheliped carpus. The new genus also shares several morphological features with Yagerocaris Kensley, 1988, which represents one of the least derived lineages within the family Alpheidae.

Résumé [+] [-]In this report, we analyze the phylogeny of Pycnogonida using the three nuclear and three mitochondrial markers currently sequenced for studying inter- and intrafamilial relationships within Arthropoda: 18S and 28S rRNA genes, Histone H3, cytochrome c oxidase subunit 1 (CO1), 12S and 16S rRNA genes. We identify several problems in previous studies, due to the use of inappropriate sequences (taxonomic misidentification, DNA contamination, sequencing errors, missing data) or taxa (outgroup choice). Our analyses show that most markers are not powerful to study the phylogeny of sea spiders. The results suggest however a recent diversification of the group (Mesozoic rather than Paleozoic) and the early divergence of Austrodecidae, followed by Colossendeidae. Pycnogonidae and Rhynchothoracidae. Except Ammotheidae and Callipallenidae, all other families were recovered as monophyletic. Analyses of synonymous sites in CO1 sequences reveal an extreme heterogeneity of nucleotide composition within sea spiders, as six unrelated species show a reverse strand-specific bias. We therefore suggest that several independent reversals of asymmetric mutational constraints occurred during the evolution of Pycnogonida, as a consequence of genomic inversions involving either the control region or a fragment containing the CO1 gene. These hypotheses are supported by the comparison of two complete mitochondrial genomes of sea spiders (Achelia bituberculata and Nymphon gracile) with that of Limulus. (C) 2010 Academie des sciences.

Résumé [+] [-]The present study is based on material collected in the intertidal and shallow subtidal areas of two Islands in the Persian Gulf, Abu-Musa and Larak. The new species, Synalpheus pentaspinosus n. sp., is closely related to S. quinquedens Tattersall, 1921. These two species share a very characteristic, sixth pleonite armed posteriorly with five stout sharp teeth, a feature unique within the genus. The color of ovaries or freshly laid eggs, red-orange in S. pentaspinosus n. sp. vs. green in S. quinquedens, is the most obvious character, by which the new species may be distinguished from S. quinquedens in the field. In addition, the two species can be separated by two characters on the dactylus of the minor cheliped. In the new species, the dactylus is furnished with two prominent rows of setae, one dorsally and one mesially, and has a small concavity on the cutting edge, contrasting to only one mesial row of setae and no obvious concavity in S. quinquedens.

Résumé [+] [-]The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

Résumé [+] [-]The deep-water alpheid shrimp Batella praecipua De Grave, 2004 was originally described based on two incomplete specimens, both with their first chelipeds missing, collected at 400–440 m off New Caledonia. During the recent KANADEEP 1 expedition in the Coral Sea in 2017, the first complete specimen of B. praecipua was collected at a depth of 370–380 m. The morphology of this specimen is presented in detail, with emphasis on the highly diagnostic chelipeds, which are described and illustrated for the first time. A slight intraspecific variation of B. praecipua is reported and a DNA barcode (CO1) is provided for this species. The main differences between the three presently known species of Batella Holthuis, 1955 are discussed.

Audo D., Hyžný M. & Charbonnier S. 2018. The early polychelidan lobster Tetrachela raiblana and its impact on the homology of carapace grooves in decapod crustaceans. Contributions to Zoology: 17
Résumé [+] [-]Polychelidan lobsters, as the sister group of Eureptantia (other lobsters and crabs), have a key-position within decapod crustaceans. Their evolutionary history is still poorly understood, although it has been proposed that their Mesozoic representatives largely inhabited shallow-marine environment and only later sought refuge in deep water. This view has recently been challenged, so the evolutionary history of polychelidans is in a need of re-appraisal. The earliest representatives, such as Tetrachela from the Late Triassic of Austria and Italy, are of great importance because of their potential in investigation of life habits of early polychelidans. Tetrachela lived in a relatively deep water, however, its well-developed eyes suggest an environment where light was still present. With its massive dorsoventrally flattened body plan, Tetrachela was probably benthic; the shape of its mandible and stocky first pereiopods suggest it was a scavenger and/or fed on slowly moving or sedentary animals. The carapace of Tetrachela has a peculiar groove pattern, which leads us to redefine some elements of the nomenclature of grooves used for polychelidans. Based on the present revision we propose that the second incision and its associated groove correspond to the hepatic groove, not the postcervical or the branchiocardiac grooves as interpreted previously. This revision allows us to review the homologies of cephalothoracic groove between polychelidans and other notable groups of decapod crustaceans.

Résumé [+] [-]Polychelidan lobsters are a group of decapod crustaceans which, in terms of both numbers of species and morphology, were more diverse during the Triassic and Jurassic than their modern representatives (Polychelidae). Here a new genus and species from the Lower Jurassic of Switzerland, Angusteryon oberlii, is described. The new taxon is characterised by a particularly narrow cephalothoracic shield, which is an unusual trait in comparison to all other polychelidan lobsters, both fossil and extant. It is tentatively assigned to the Coleiidae here. A. oberlii nov. gen., nov. sp. was recovered from hemipelagic sedimentary rocks, suggesting that it inhabited a deep-water setting. Although there is a possibility that the present specimens could be parautochthonous, the small size of the ocular incisions may indicate that A. oberlii nov. gen., nov. sp. had either reduced vision or was blind, which could be explained by its having inhabited a deep-water habitat. If our views on this mode of life and taxonomic assignment are correct, this would suggest convergent degeneration of vision between the new taxon and the Polychelidae. Furthermore, features of the newly collected specimen augment the apparent morphological diversity displayed by polychelidan lobsters early in their history, as well as document a more substantial decrease of such since the Triassic and Jurassic than previously recorded.

Résumé [+] [-]During the past decade, a large number of multi-gene analyses aimed at resolving the phylogeneticrelationships within Decapoda. However relationships among families, and even among sub-families, remain poorly defined. Most analyses used an incomplete and opportunistic sampling of species, but also an incomplete and opportunistic gene selection among those available for Decapoda. Here we test in the Caridea if improving the taxonomic coverage following the hierarchical scheme of the classification, as it is currently accepted, provides a better phylogenetic resolution for the inter-families relationships. The rich collections of the Muse´um National d’Histoire Naturelle de Paris are used for sampling as far as possible at least two species of two different genera for each family or subfamily. All potential markers are tested over this sampling. For some coding genes the amplification success varies greatly among taxa and the phylogenetic signal is highly saturated. This result probably explains the taxon-heterogeneity among previously published studies. The analysis is thus restricted to the genes homogeneously amplified over the whole sampling. Thanks to the taxonomic sampling scheme the monophyly of most families is confirmed. However the genes commonly used in Decapoda appear non-adapted for clarifying inter-families relationships, which remain poorly resolved. Genome-wide analyses, like transcriptome-based exon capture facilitated by the new generation sequencing methods might provide a sounder approach to resolve deep and rapid radiations like the Caridea.

Résumé [+] [-]Examination of materials collected from Indonesia, New Caledonia and vicinity, now deposited in the Museum National d'Histoire Naturelle, disclosed three additional undescribed species of chirostylids belonging to the Uroplychus spinimarginatus group. The group is now shifted to a distinct genus Uroptychodes. Uroptychus grandirostris Yokoya, 1933, which can be transferred to Uroptychodes, has been a problematic species because of the brevity of the original description and the loss of the type material. However, a recent finding of a specimen, which is in poor condition, very much like the illustration of U. grandirostris by Yokoya (1933: Fig. 29), but different from the description of U. grandirostris given by van Dam (1939) for one of the type specimens, suggests that the type material of U. grandirostris includes at least two species. In this paper a neotype is selected for U. grandirostris. The genus Uroptychodes now contains 10 species. All these species are reviewed and a key to the species of the genus is provided.

Résumé [+] [-]Eight species of squat lobsters of the genus Uroptychus are reported from the western Atlantic based on the collections of the Museum of Comparative Zoology at Harvard, the Smithsonian Institution and Texas A&M University. Uroptychus nitidus (A. Milne-Edwards, 1880) is reviewed and redescribed, with a syntype taken at Blake Station 200 off Martinique designated as the lectotype. Uroptychus alphonsei n. sp. is named for U. nitidus variety C Chace, 1942, U. fenneri n. sp. for U. nitidus variety A Chace, 1942, and U. janiceae n. sp. for U. nitidus variety B Chace, 1942; U. lindae n. sp. is described on the basis of specimens collected by the Alaminos in the Caribbean Sea off northern Columbia; U. rafai n. sp. is described based on a sole specimen taken from the Straits of Florida; U. reedae n. sp. is described from among the syntypes of U. nitidus; and U. uncifer (A. Milne-Edwards, 1880) is redescribed to elaborate on its specific status, with the designation of lectotype from Blake Station 299 off the coast of Barbados. The number of species of Uroptychus from the western Atlantic now stands at 21. A key to these species is provided.

Baba k. 2005. Deep-sea chirostylid and galatheid crustaceans (Decapoda: Anomura) from the Indo-Pacific, with a list of species. GALATHEA REPORT 20: 5-317
Résumé [+] [-]Deep-sea chirostylid and galatheid crustaceans collected during the "Galathea" Expedition 1950-52, Kei Islands Expedition 1922, and by Th. Mortensen, and others now in the collection of the Zoological Museum, Copenhagen constitute the basis of this paper. They comprise 864 specimens, 105 of which are distributed among 38 species in five genera of Chirostylidae (one in Chirostylus Ortmann, 1982; five in Eumunida Smith, 1883; three in Gastroptychus Caullery, 1896; one in Pseudomunida Haig, 1979; three in Uroptychodes Baba, 2004; and 25 in Uroptychus Henderson, 1888). The remaining 759 specimens belong to Galatheidae, with 94 species in 13 genera, including two new genera (three in gononida Baba & de Saint Laurent, 1996; two in Bathymunida Balss, 1914; one in Enriquea n. gen.; eight in Galathea abricius, 1793; one in Heteronida Baba & de Saint Laurent, 1996; one in Leiogalathea Baba, 1969; 29 in Munida Leach, 1820; 38 in Munidopsis Whiteaves, 1874; six in Paramunida Baba, 1988; two in Phylladiorhynchus Baba, i969; one in Raymunida iviacpherson 22 Machordom, 2000; one in Sadayoshia Baba, 1969; and one in Torbenia n. gen.). Twenty-nine new species are described: one of Gastroptychus, nine of Uroptychus, three of Galathea, five of Munida, 10 of Munidopsis, and one of Torbenia. Three species (two of Munida and one of Raymunida) that have depth records exceeding 200 m, but which in the present collection are available from the continental shelf, are incorporated in this report. Chirostylus ciliatus van Dam, 1933 and Gastroptychus chacei Baba, 1986, are transferred to Uroptychus, Munida leviantennata Baba, 1988 is transferred to Enriquea, as also is Agononida insolita Macpherson, 2004 to Torbenia. Examination of the type material of Munida quinquespinosa Balss, 19 13 reveals that it belongs to Galathea. All species are diagnosed and if new, the holotype is described. In order to clarify the identity of some species, type material and/or comparative material from repositories other than the Copenhagen Museum is included in the report (for Uroptychus latirostris, U. tridentatus, and Munidopsis subsquamosa). Color notes are given when available, and geographic and depth distributions are summarized for the species included in the collection. A list of 580 deep-sea species (161 species in six genera of Chirostylidae and 419 species in 26 genera of Galatheidae) known or supposed to occur at depths exceeding 200 m in the Indo-Pacific, including the Southern Ocean, is provided, along with a key to species of each genus where necessary. For each species, synonymy including reference(s), locality and depth records, and the repository and registration number of the type material are given where possible. Brief comments on vertical and horizontal distributions of species are given for multi-species genera.

Résumé [+] [-]Pycnogonid material collected between August 2000 and August 2003 from Taiwanese waters at depths between 100 and 2620 m is described. The thirty-three specimens represent ten species, and include one hitherto undescribed species of each of the genera Nymphon, Colossendeis and Pycnogonum. There are no previously published records of pycnogonids from Taiwan. Nymphon polyglia sp. nov. has multiple cement gland pores on the femur and first tibia, and tarsus and propodus subequal in length. Colossendeis mycterismos sp. nov. has affinities with C. pipetta, but has a tarsus shorter than the propodus. Pycnogonum cranaobyrsa sp. nov. has a slender tapering proboscis, no auxiliary claws and pointed mid-dorsal trunk tubercles, with a pustulate integument and a rounded ocular tubercle. The cement-gland openings of Heterofragilia hirsuta are described.

Résumé [+] [-]The Pacific collections by the MUSORSTOM campaigns of the Museum national d'Histoire naturelle, Paris, over the last 20 years have included a number of Tanaidacea from waters of the New Caledonia region. The species described herein as Mekon solidomala, from 440 and 700 m depth, represents a new tanaid genus and species of the subfamily Langitanainae of the family Tanaidae. While displaying the ventrally fused pleonites four and five and the four-segmented antennule characteristic of the subfamily, it is distinct from the two previously knewn genera in having a non-flagelliform, four-segmented uropod, massive mandibles, and a Iarge, subspherical carapace, the posterodorsal part of which overlaps the first and most of the second pereonite. One tanaid paratype bore a copepod parasite representing a new genus and species of the family Nicothoidae, Arhizorhina mekonicola. This new genus appears most closely related to Rhizorhina in its extreme reduction of body segmentation and tagmosis, and in the total loss of limbs; however, it lacks the branching rootlet system that is diagnostic for Rhizorhina, and the stalk is configured differently.

Résumé [+] [-]The Pacific collections by the French campaigns over the last 20 years included a total of six species of apseudomorph tanaidaceans from the bathyal slope off the coast of New Caledonia at between 410 and 1807 m depth. All of these species were new to science, and are described herein. Th ree are in the family Apseudidae, viz. Apseudes batillus n. sp., characterized by a scooped, down-curving rostrum and a spinous apophysis on antennule peduncle article 1, A. coriolis n. sp., with a reduced antennal squama and reduced pleopods unusual for the genus, and Atlantapseudes cyanea n. sp., close to the type species of the genus A. nigrichela Băcescu, 1978, but without the prominent anterolateral spine-like apophysis on pereonite 2 of that species. The other three species are in the family Pagurapseudidae, viz. Indoapseudes choristhema n. sp., characterized by its extremely reduced antenna and lack of an exopodite on the cheliped, Macrolabrum distonyx n. sp., the deepest recorded species of this genus, with characteristic antennular and rostrum morphology, and Pagurapseudes inquilinus n. sp., also distinguished by the segmentation of the antennular flagella and trunk-segment proportions, inter alia.

Résumé [+] [-]Deep-sea pycnogonid material collected during the N/O Alis Campagnes Norfolk 2 to New Caledonia in 2003 and Salomon 2 to the Solomon Islands in 2004, together with two samples from the BOA0 and BOA1 Campagnes to Vanuatu in 2004-2005, has been analyzed. This includes only the second collection of deep-sea pycnogonids from the Solomon Islands. The material includes 22 specimens from seven species from New Caledonia, taken at depths from 265 to 1150 m, 95 specimens from 14 species from the Solomon islands, at depths from 336 to 1218 m, and two specimens of one species from Vanuatu (864-927 m depth). The first male of Ascorhynchus constrictus is described, including the first description of the anterior legs. A new species of Ascorhynchus is partially described, but not named owing to its incompleteness. Seven of the species are new to the Melanesia region, including a notable range-extension for Colossendeis tasmanica. The local zoogeography of these deep-water species is discussed.

Résumé [+] [-]With over 1600 extant described species, the Muricidae are one of the most species-rich and morphologically diverse families of molluscs. As predators of molluscs, polychaetes, anthozoans barnacles and other invertebrates, they form an important component of many benthic communities. Traditionally, the classification of muricids at specific and generic levels has been based primarily on shells, while subfamilies have been defined largely by radular morphology, although the composition and relationships of suprageneric groups have never been studied exhaustively. Here we present the phylogenetic relationships of 77 muricid species belonging to nine of the ten currently recognized subfamilies, based on Bayesian inference and Maximum Likelihood analyses of partial sequences of three mitochondrial (12S, 16S and COI) and one nuclear (28S) genes. The resulting topologies are discussed with respect to traditional subfamilial arrangements, and previous anatomical and molecular findings. We confirm monophyly of each of the subfamilies Ergalataxinae, Rapaninae, Coralliophilinae, Haustrinae, Ocenebrinae and Typhinae as previously defined, but earlier concepts of Muricinae, Trophoninae and Muricopsinae are shown to be polyphyletic. Based on our phylogenetic hypothesis, a new arrangement of these subfamilies is proposed.

Résumé [+] [-]The Glypheidea is a group of lobster-like decapods that appeared in the Triassic and that was thought to be extinct until 1975, when a specimen of the species Neoglyphea inopinata was caught off the Philippines. More recently, in 2005, a specimen of another glypheid species, Laurentaeglyphea neocaledonica, was discovered near New Caledonia. Here, we construct a decapod molecular data set including the two extant glypheid species sequenced from eight nuclear and mitochondrial genes. Our study strongly shows that the two extant genera of glypheids cluster together, and further confirms the status of Glypheidea as a separate infraorder. Moreover the reptantian decapods are divided into two major groups, one including Brachyura, Anomura, and Axiidea, and the other including Astacidea, Polychelida, Achelata, and Glypheidea. Although commonly nicknamed 'Jurassic shrimps' and considered as 'living fossils', glypheids are therefore a derived decapod lineage. (C) 2010 Academie des sciences. Published by Elsevier Masson SAS.

Résumé [+] [-]Two new species of the parasitic copepod genus Dissonus Wilson, 1906 are described: D. excavatus n. sp. from the gills of a labrid, Bodianus perditio, and a lutjanid, Macolor niger, collected off New Caledonia and Taiwan, and D. inaequalis n. sp. from a hemiscylliid elasmobranch, Chiloscyllium punctatum, collected off Sarawak (Malaysia) and the Philippines. Material of D. heronensis Kabata, 1966 is described from a balistid host, Pseudobalistes fuscus, off New Caledonia, and this constitutes a new host record for this parasite. D. manteri Kabata, 1966 was collected from four serranid host species off New Caledonia and from one of the same hosts off Taiwan. Two of the hosts from New Caledonia, Plectropomus laevis and Epinephelus cyanopodus, represent new host records. D. pastinum Deets & Dojiri, 1990 was recognised as a new synonym of D. nudiventris Kabata, 1966, so the total number of valid species is now twelve. Material from museum collections of D. nudiventris, D. similis Kabata, 1966 and D. spinifer Wilson, 1906 was re-examined and provided new information which is utilised in a key to all valid species of Dissonus.

Twi closely related, and often synonymizes species of Albunea: A. microps Miers, 1878 and A. elioti Benedict, 1904 are found to be distinct. Several important diagnostic morphological features, not previously described in the Albueidae, are discussed. In addition, we provide diagnoses for three Indo-West species of mole crabs in the family Hippidae Latreille, 1825, including the very similar Hippa pacifica Dana, 1852 and H. celaeno (de Man, 1986). An annotated list of the 37 species of Hippoidea reported from the Indo-West Pacific region is provided, along with a diagnostic key to these species.

Boyko C.B. 2000. The Hippoidea (Decapoda, Anomura) of the Marquises Islands, with description of a new species of Albunea. Zoosystema 22(1): 107–116
Résumé [+] [-]The hippoid fauna of the Marquises Islands is summarized, based primarily on materials collected by MUSORSTOM 9. A new species of sand crab of the family Albuneidae, Albunea marquisiana, is described based on a sample size that is unusually large for an albuneid. This new species is characterized by the shape of the dactyli, the spatulate and inflated form of the male telson and the composition of the carapace groove 10 and 11, which are broken into smaller elements. It is most closely related to A. holthuisi Boyko & Harvey, 1999, which occurs in the Indo-Pacific from Madagascar eastward to Indonesia. New records are given for A. speciosa Dana, 1852, the first record of this species from the Marquises Islands, and Hippa adactyla Fabricius, 1787.

Boyko C.B. 2002. A WORLDWIDE REVISION OF THE RECENT AND FOSSIL SAND CRABS OF THE ALBUNEIDAE STIMPSON AND BLEPHARIPODIDAE, NEW FAMILY (CRUSTACEA: DECAPODA: ANOMURA: HIPPOIDEA). Bulletin of the American Museum of Natural History 272: 1-396. DOI:10.1206/0003-0090(2002)272<0001:AWROTR>2.0.CO;2
Résumé [+] [-]The anomuran sand crab family Albuneidae sensu stricto was previously known worldwide from 41 validly described Recent species in eight genera and four fossil taxa of the genus Albunea. A worldwide revision is presented based on a comprehensive survey of the literature and examination of more than 1700 specimens representing all known species. The state of taxonomic knowledge regarding the Albuneidae is summarized; the family is divided into two new subfamilies; two new genera and six new species of albuneids are described; and new information on species’ ranges and biology is presented. Additionally, the genera Blepharipoda Randall and Lophomastix Benedict are removed from the Albuneidae and placed in a new family, based in part on characters of the gill formula and morphology. This new family contains six Recent species and one fossil taxon. Although there is some doubt about its hippoid affinities, it is retained in the Hippoidea as the most basal taxon, pending further cladistic phylogenetic analyses. Here and there are people with eyes which can see, minds which can correlate. They say to themselves: ‘‘If the science of the day before yesterday is rejected by the people of yesterday, and that of yesterday by us of today, is it not possible that what we call science now will be rejected by the men of tomorrow?’’ And the bravest of them answer, ‘‘It is possible.’’ Wassily Kandinsky, 1911, Concerning the Spiritual in Art

Résumé [+] [-]Asymmetrorbione drepanopleon n. gen., n. sp., a highly asymmetrical orbionme bopyrid isopod, is described from specimens of two species of Sicyonia H. Milne Edwards, 1830, shrimp collected by the MUSORSTOM expeditions in New Caledonia; it is the seventh genus included in the Orbioninae. This genus can be characterized by the female having coxal plates well developed on the longer side of the body, a pleon with five pleomeres plus pleotelson, pleomeres I-V having biramous pleopods and uniramous lateral plates, the short side of the body with reduced lateral plates and the long side of the body with lateral plates elongated on pleomeres I and II, all lateral plates smooth, and uniramous uropods. The male has all pleonal segments plus the pleotelson fused into a single segment and lacking midventral tubercles, pleopods, and uropods. A second species, Orbione kempi Chopra, 1923, is also transferred to the new genus. Comparisons are made between Asymmetrorbione n. gen. and Anisorbione Bourdon, 1981, females of which differ in having only five pleonal segments and biramous uropods, and Orbione Bonnier, 1900, females of which differ in their lack of pronounced asymmetry of the pleon and lateral plates and in the presence of tubercles on the lateral plates.

Résumé [+] [-]Two new species of bopyrid isopods, Pseudione stylopoda n. sp. and P. clevai n. sp., are reported from species in the family Stylodactylidae and are the first species described from members of this enigmatic caridean family. One of the new species is very close to the New Zealand taxon P. pontocari Page, 1985, especially in the form of the distinctive styliform shape of the endopods of pleopods IV and V in the female. The second new species has some similarity to P. elongata elongata (Hansen, 1897) in the shape of the female pleotelson, but is otherwise very distinctive within the genus. Additional literature records of bopyrids from species of Stylodactylidae for which specimens cannot be located are discussed.

Résumé [+] [-]This study adds 8 bopyrids to the 5 species previously known from Taiwan. None of the species are new to science, but all are new to the Taiwanese fauna. All of the hosts for the 8 species are new. Four species redescribed herein, Pseudione retrorsa Richardson, Parioninella obovata Shiino, Parapenaeon tertium Nierstrasz and Brender 6 Brandis, and Bopyrus stebbingi Nierstrasz and Brender Brandis, are reported for the 1st time since their original descriptions, with each representing a substantial range extension. The geographic and depth distributions of 2 additional species, Bopyroides hippolytes (Kroyer) and Athelges takanoshimensis Ishii, are greatly extended. Two new genera are erected for P. obovata and B. stebbingi. Pseudione lenticeps Shiino is synonymized with P. retrorsa, which is transferred to the genus Aporobopyrus Nobili. Parapenaeon coarctatum tuberculata is raised to the level of full species. Identifications of hosts as cited in older literature are updated to current nomenclature.

The Emergence of Lobsters: Phylogenetic Relationships, Morphological Evolution and Divergence Time Comparisons of an Ancient Group (Decapoda: Achelata, Astacidea, Glypheidea, Polychelida). Systematic Biology 63(4): 457-479. DOI:10.1093/sysbio/syu008
Résumé [+] [-]Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders Polychelida, Glypheidea, Astacidea andAchelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and “living fossil” species. The high degree of morphological diversity among these infraorders has led to a dynamic classification and conflicting hypotheses of evolutionary relationships. In this study, we estimated phylogenetic relationships among the major groups of all lobster families and 94% of the genera using six genes (mitochondrial and nuclear) and 195 morphological characters across 173 species of lobsters for the most comprehensive sampling to date. Lobsters were recovered as a non-monophyletic assemblage in the combined (molecular + morphology) analysis. All families were monophyletic, with the exception of Cambaridae, and 7 of 79 generawere recovered as poly- or paraphyletic. A rich fossil history coupled with dense taxon coverage allowed us to estimate and compare divergence times and origins of major lineages using two drastically different approaches. Age priors were constructed and/or included based on fossil age information or fossil discovery, age, and extant species count data. Results from the two approaches were largely congruent across deep to shallow taxonomic divergences across major lineages. The origin of the first lobster-like decapod (Polychelida) was estimated in the Devonian (∼409–372 Ma) with all infraorders present in the Carboniferous (∼353–318 Ma). Fossil calibration subsampling studies examined the influence of sampling density (number of fossils) and placement (deep, middle, and shallow) on divergence time estimates. Results fromour study suggest including at least 1 fossil per 10 operational taxonomic units (OTUs) in divergence dating analyses.

Résumé [+] [-]A single specimen of a small new hippolytid shrimp, captured between 65-120 m off New Caledonia, is described and illustrated. A new genus, Gelastreutes, is designated for its accommodation, indicating its relationship with the genera Gelastocaris Kemp, Latreutes Stimpson and Paralatreutes Kemp. The new species, G. crosnieri, is remarkable for its robust, nighly calcified body and its similarity in general body form to Gelastocaris paronae suggests that it is also probably a commensal species, possibly an associate of sponges.

Résumé [+] [-]A small collection of palaemonoid shrimps, mainly Pontoniinae, from New Caledonian waters of over 100 m depth, has been studied and found to represent 27 taxa, including eight new species of Periclimenes, one new species of both Periclimenaeus and Mesopontonia, and three specimens, including a single ovigerous female, representing a new genus, Amphipontonia kanak. Seven species were recorded from New Caledonian waters for the first time. The species of Periclimenaeus, from 370-450 m, represents the greatest depth from which this mainly shallow-water genus has been reported. Two species, a Periclimenes and a Mesopontonia, both new, were found together in association with a hexactinellid sponge host, Phoronema sp., the first reported association of pontoniine shrimps with a hexactinellid host. Another new Periclimenes, with a remarkable pectinate ambulatory dactylus, is also possibly associated with the "living fossil" crinoid, Gymnocrinus richeri. The present study increases to 57 the number of palaemonoid shrimps known from Indo-West Pacific marine waters exceeding 100 m depth, and clearly indicates that these shrimps are quite well represented in deeper tropical seas. A list of the Indo-West Pacific palaemonoid shrimps known from over 100 m depth, with a new key to the deep-water Indo-West Pacific species of the genus Periclimenes is provided.

Résumé [+] [-]A collection of 52 species of palaemonoid shrimps from the Muséum national d'Histoire naturelle, Paris, is reported upon. Material is derived principally from the New Caledonian region but also includes specimens from Aden/Yemen, Comoro Islands, western Indian Ocean, Philippines, Indonesia and Wallis Island. Specimens have been collected from intertidal depths to over 600 m. Ten species have been collected from water depths of over 100 m. Two new genera of pontoniine shrimp are designated : Climeniperaeus, for Periclimenaeus truncoideus Chace & Bruce, 1993, and Typtonychus, for a new species, T. crassimanus. The following species are transferred from the genus Typton to the new genus Typtonychus : T. anomalus (Bruce, 1979), T. dentatus (Fujino & Miyake, 1969), and T. dimorphus (Bruce, 1986). These species are probably all associates of Porifera. Six new species of pontoniine shrimp are described. These include Conchodytes philippinensis, from an unknown locality in the Philippines; Mesopontonia verrucimanus, from 184-186 m in the Tanimbar Islands, Indonesia; Periclimenaeus colodactylus, from 20-25 m in New Caledonia, in association with Diplosoma versicolor Monniot; Periclimenes involens, from 92-97 m, off Mindoro, Philippines, of unknown association; Pontonia compacta, from 10- 60 m, in New Caledonia, in association with Pyura albaneyensis Michaelson and Pontonia simplicipes, from 71 m, in the Chesterfield Islands, in association with Pyura nigricans Heller.

Résumé [+] [-]Two new genera and four new species of Cirolanidae are reported from deep water (c. 440-2,050 m) off New Caledonia. These are Scutulana pezata, gen. nov., sp. nov., Sintorolana atrox gen. nov., sp. nov., Metacirolana neocaledonica sp. nov. and Politolana crosnieri sp. nov. Scutulana is distinguished by the unique pleonal morphology which has pleonites 4 and 5 laterally reduced but not overlapped by pleonite 3, morphology of the frontal lamina, by several mouthpart characters and by pereopod 1 having a setal brush on the dactylus. Sintorolana is closely related to Natatolana, and is distinguished from that genus and the other cirolanid genera by the expanded propodus of the anterior pereopods which are also heavily armed with spines and the elongate haptorial dactylus which extends to the merus. Metacirolana neocaledonica is closely allied to M. fornicata Mezhov, 1981, from which it is distinguished by the ornamentation of the pleotelson. These two species are separated from all others in the genus by the frontal lamina having an acute anteromedial point. Politolana crosnieri sp. Nov., the second record of the genus from beyond Atlantic waters, differs from other species of the genus in having a longer uropodal exopod, a pentagonal frontal lamina, and in the proportions of the antennule peduncle articles.

Résumé [+] [-]Three new species of Tridentella Richardson, 1905 are described from the New Caledonia region. All three species are smooth bodied or largely smooth bodied, and all were collected from the shelf around New Caledonia at depths from 150–760 metres. Tridentella palmata sp. nov. is characterised by pereopod 4 having numerous large robust setae on the carpus and an exceptionally long dactylus (7.0 times as long as proximal width); Tridentella katlae sp. nov. is the only species in the genus with medially united eyes that fill the head in dorsal view; Tridentella magna sp. nov. is the largest species in the genus (36 mm) and can be identified by the head having an anterior submarginal ridge and three submarginal tubercles on the poster margin. Tridentella takedai Nunomura 2006 (off Arasaki, Hokusuka-Shi, Kyushu, Japan) is formally transferred to Alcirona Hansen, 1905, forming Alcirona takedai (Nunomura, 2006) comb. nov.

Résumé [+] [-]An unknown hitherto disto-ventral organ of the sixth abdominal segment in shrimps is described. This organ is a complex of twin sections of modified integument and related rows of setas. It is of great taxonomic importance. The presence of this organ allows one to ascertain that typical series of some species from this genus is a mixture of various species. The revision of six species, determined by Bate (1888), resulted in reduction of N. intermedius and N. parvidentatus to the synonyms, N. productus Bate, 1888 and N. tenuipes Bate, 1888, respectively. Diagnoses of N. productus, N. tenuipes, and N. proximatus are making more exact. N. serratirostris Burukovsky, 1991 is considered as a synonym of N. tenuipes.

Résumé [+] [-]The description and comparative characteristic of three vicariated Indo-West Pacific species from the genus Nematocarcinus (N. tenuirostris Bate 1888 and N. pseudocersor Burukovsky, 1990 are previously known; N. alisae Burukovsky s. n. is new) are given. They are distinguished from other known species of the genus by similarity in structure of the distro-ventral organ of the 6th abdominal segment. In these species, spots of the distro-ventral organ are located on an original protuberance forming in the distal quarter of ventral segment surface - blister. The spots are always located in close proximity to each other. These species are primarily distinguished by their rostrum structure.

Résumé [+] [-]A type series of Nematocarcinus gracilis Bate 1888 and collections of prawns previously attributed to this species were investigated. The type series appear to be a mixture of two species. The lectotype and paralectotype of N. gracilis and the new species, N. pseodogracilis, are described. The main difference between the new species and N. gracilis is the structure of the disto-ventral organ of the sixth abdominal segment. The distance between the organ spots in the new species does not reach the width of a spot, whereas this distance is 2-3 times wider than in the typical form. Both species inhabit Indo-Western Pacific region, but N. pseudogracilis does not occur to the north of 20°s

Résumé [+] [-]During the recent Taiwan TAIWAN and the Philippines PANGLAO 2005 and AURORA deep-sea expeditions, many specimens of nematocarcinid shrimp were collected. Altogether three genera and 13 species are identified: Nigmatullinus acanthitelsonis (Pequegnat, 1970), Segonzackomaius altus (Bate, 1888), Nematocarcinus chacei Burukovsky, 2002, N. combensis Burukovsky, 2000, N. crosnieri Burukovsky, 2000, N. gracilis Bate, 1888, N. productus Bate, 1888, N. rectirostris Burukovsky, 1991, N. richeri Burukovsky, 2000, N. subtegulisfactus Burukovsky, 2000, N. subtilis Burukovsky, 2000, N. tenuipes Bate, 1888 and N. tenuirostris Bate, 1888. Amongst them, S. altus, N. chacei and N. crosnieri are the second records since their original descriptions. Moreover, two genera and 11 species are new records for Taiwan while two species are new Philippine records. Diagnoses for the family, subfamilies, and genera and a key to all species of Nematocarcinus A. Milne-Edwards, 1881 are given. Colour photographs of 10 species are also provided. The studied area was subdivided into northern and southern subareas. The northern area includes the waters around Taiwan (21°18’-25°22’N and 117°17’-123°01’E), and the southern area the waters of the Philippines (08°33’-16°06’N and 121°30’-124°10’E). Five species occur in both subareas. A comparison of the present data with the known data on the nematocarcinid shrimp fauna of the Indo-Malay area or East Indies Triangle (i.e. the centre of species diversity of shrimps of family Nematocarcinidae) revealed that the area between Taiwan and the northern Philippines is an ecotone, with a transitional nematocarcinid shrimp fauna between the fauna of the East Indies Triangle and the typical Indo-West-Pacific fauna.

Résumé [+] [-]In a previous phylogenetic analysis of numerous species of the genus Munida and related genera from the West Pacific based on molecular and morphological data, the monophyly of this group with the exception of M. callista was established. Morphologically, M. callista is closely related to M. brucei, M. javieri, M. hystrix and M. plexaura showing morphological differences in the shape of the rostrum, the supraocular spines, and the ridges on the epistome with respect to the genus Munida. Moreover, the analysis of the mitochondrial genes 16S rRNA and COI showed an independent and monophyletic lineage from the genus Munida. Therefore a new genus, Babamunida, is proposed to accommodate these five species, based on morphological characters and molecular data.

Résumé [+] [-]The family Galatheidae is among the most diverse families of anomuran decapod crustaceans, and the South-West Pacific is a biodiversity hot spot for these squat lobsters. Attempts to clarify the taxonomic and evolutionary relationships of the Galatheidae on the basis of morphological and molecular data have revealed the existence of several cryptic species, differentiated only by subtle morphological characters. Despite these efforts, however, relationships among genera are poorly understood, and the family is in need of a detailed systematic review. In this study, we assess material collected in different surveys conducted in the Solomon Islands, as well as comparative material from the Fiji Islands, by examining both the morphology of the specimens and two mitochondrial markers (cytochrome oxidase subunit 1, COI, and 16S rRNA). These two sources of data revealed the existence of eight new species of squat lobster, four of which were ascribed to the genus Munida, two to the genus Paramunida, one to the genus Plesionida, and the last species was ascribed to the genus Agononida. These eight species are described along with phylogenetic relationships at the genus level. Our findings support the taxonomic status of the new species, yet the phylogenetic relationships are not yet fully resolved. Further molecular analysis of a larger data set of species, and more conserved genes, will help clarify the systematics of this group.

Résumé [+] [-]The genus Paramunida belongs to the family Galatheidae, one of the most species rich families among anomuran decapod crustaceans. In spite of the genus has received substantial taxonomic attention, subtle morphological variations observed in numerous samples suggest the existence of undescribed species. The examination of many specimens collected during recent expeditions and morphological and molecular comparisons with previously described species have revelaled the existence of eleven new lineages. All of them are distinguished by subtle and constant morphological differences, which are in agreement with molecular divergences reported for the mitochondrial markers ND1 and 16S rRNA. Here, we describe and illustrate the new species, providing brief redescriptions for the previously known species, and a dichotomous identification key for all species in the genus.

Résumé [+] [-]The genus Allogalathea was established by Baba in 1969 to include the well-known species Galathea elegans. This species is widely distributed across the Indo-West Pacific Ocean, and is characterized by living in close association with crinoids, and by its conspicuous coloration. Although the genus is considered monospecific, different colour patterns and discrete morphological variations mainly associated with the rostrum and chelipeds have been reported. These differences could point to cryptic species, thereby questioning Allogalathea as a monotypic taxon. To address this issue, we sequenced the mitochondrial cytochrome oxidase I (COI; 658 bp) and 16S rRNA (882 bp) genes and the nuclear gene phosphoenolpyruvate carboxykinase (PEPCK; 598 bp) in numerous specimens from eight different localities, and also examined their morphological characters. DNA sequences were analysed using maximum-parsimony, maximum-likelihood, and Bayesian approaches of phylogenetic inference. The resulting trees were combined with morphological evidence to test species boundaries. Our molecular data revealed four deeply divergent clades, which can be distinguished by subtle morphological differences in the spinulation and length: breadth ratio of the P1 carpus, spinulation of the walking legs, and shape of the rostrum. Our findings indicated that Allogalathea elegans is in fact a species complex comprising four different species, which, although genetically very distinct, are morphologically very similar. We provide morphological descriptions and a key to these four species of the genus.

Résumé [+] [-]The diversification of Indo-Pacific marine fauna has long captivated the attention of evolutionary biologists. Previous studies have mainly focused on coral reef or shallow water-associated taxa. Here, we present the first attempt to reconstruct the evolutionary historyphylogeny, diversification, and biogeographyof a deep-water lineage. We sequenced the molecular markers 16S, COI, ND1, 18S, and 28S for nearly 80% of the nominal species of the squat lobster genus Paramunida. Analyses of the molecular phylogeny revealed an accelerated diversification in the late OligoceneMiocene followed by a slowdown in the rate of lineage accumulation over time. A parametric biogeographical reconstruction showed the importance of the southwest Pacific area, specifically the island arc of Fiji, Tonga, Vanuatu, Wallis, and Futuna, for diversification of squat lobsters, probably associated with the global warming, high tectonic activity, and changes in oceanic currents that took place in this region during the OligoceneMiocene period. These results add strong evidence to the hypothesis that the Neogene was a period of major diversification for marine organisms in both shallow and deep waters.

Résumé [+] [-]The genus Paramunida belongs to the most diverse family of galatheoids and it is commonly reported from the continental slope across the Indian and Pacific Oceans. Examination of material collected by the NOAA RV Townsend Cromwell Cruise near Christmas (Kiritimati) Island, Kiribati, revealed the existence of a new species of Paramunida (P. haigae), which represents the fourth record of the genus for the Central Pacific. Furthermore, recent efforts to unravel phylogenetic relationships and diversification patterns in Paramunida revealed P. granulata (Henderson, 1885) to be the most basally diverging taxon within the genus. This species is clearly distinguished from other species of Paramunida by the spinulation of the carapace and the length of the distomesial spine of the second antennal peduncle article, which in combination with a high level of genetic divergence suggest that this species represents a separate monotypic lineage. A new genus, Hendersonida gen. n., is proposed to accommodate this species based on morphological and molecular evidence. An updated dichotomous identification key for all species of Paramunida is presented.

Résumé [+] [-]The genus Paramunida belongs to the family Munididae, one of the most speciose families among anomuran decapod crustaceans. During the PANGLAO 2004, PANGLAO 2005, and AURORA 2007 expeditions in the Philippines, eight species of the genus were collected, including a new record and three new species, namely Paramunida akaina, P. aspera, and P. aurora. These new lineages are distinguished by subtle and constant morphological differences, which are in agreement with molecular evidence from the mitochondrial markers ND1 and 16S. Here, we describe these new species, provide new distribution records, and present phylogenetic relationships within the genus.

Résumé [+] [-]Deep-sea shrimps of the species Plesionika acanthonotus (Smith, 1882) and P. holthuisi Crosnier & Forest, 1968 are morphologically similar and exhibit overlapping amphi-Atlantic distributions. In the literature, through morphological studies, there are reports of doubts about the validity of P. holthuisi and some authors believe that the eastern and western Atlantic populations of P. acanthonothus could represent two distinct species. The objective of the present study was to use molecular data to elucidate the taxonomic status of the two populations of P. acanthonothus. DNA sequences of two mitochondrial genes (16S rDNA and Cytochrome Oxidase subunit I) and a nuclear gene (Histone 3) were obtained for both species and for both populations of P. acanthonotus. The sequences were also obtained from Genbank for comparison. The trees (separate and multi-locus/partitioned genes) were generated by Bayesian Inference analyzes, and genetic divergence (Kimura-2-parameters) was also calculated. All specimens that had their DNA sequenced were examined morphologically to confirm their identification; morphological variations were noted. The genetic data showed that Plesionika holthuisi is closely related to P. acanthonotus, but clearly separated, indicating that P. holthuisi is a valid species. In the multi-locus analysis, the P. acanthonothus specimens were divided into two clades, one with the eastern Atlantic specimens and another with the western Atlantic specimens. However, this genetic separation was considered to be a population structuring for three reasons: (1) the genetic divergences of the two mitochondrial genes between these two groups (eastern Atlantic X western Atlantic) were smaller than the interspecific divergence for Plesionika; (2) the P. acanthonothus sequences of the Histone 3 gene showed no genetic variation; (3) in the analyzed individuals, no valid morphological character was found to support this separation. Thus, the conclusion of this study is that P. holthuisi probably is a valid species and P. acanthonothus presents two populations with mitochondrial divergences that could be in the process of speciation, but which currently represent only one species.

Résumé [+] [-]The inventory of epibenthic dredgings in the areas of New Caledonia, Indonesia and Wallis and Futuna Islands shows that there are 14 species of Euphausiids, of which Pseudeuphausia sinica is new for this region. Another species, Thysanopoda cornuta, sampling of which is always exceptional, leads the author to report on a closely related species, T. minyops, caught in the South of Madagascar and of which it is the second mention since its description. These two, giant, abyssal species are compared and original morphological features are described. In the Euphausiids, except petasma, modifications of the tegumental parts linked with reproduction only affect the segment bearing the gonopores, the coxae and sternites being involved in both sexes. In the females, the thelycum is a median unpaired specific modification of the sixth sternite articular sheet, partly closed by the coxal fold of the sixth thoracopods. The insertion of the spermatophores and their relation with the orifices of oviducts, situated beneath the coxae, helps in understanding the entirely external functioning of these seminal receptacles. A description of the antennular sensory setae is provided for the deep species Bentheuphausia amblyops.

Résumé [+] [-]Crustacea Mysidacea : The Lophogastrida from Indonesia, New Caledonia and Wallis and Futuna Islands. A large series of samples dredged during different cruises in the tropical western Pacific have made it possible to draw up or complete the species inventories of various regions. Thirteen species, including two new to science, were found in Indonesia (KARUBAR and ESTASE 2 cruises): Gnathophausia ingens, G. longispina, G. elegans, G. fagei sp. Nov., G. zoea, G. gracilis, Lophogaster inermis sp. Nov., L. manilae, L. rotundatus, Paralophogaster glaber, P. philippinensis, P. boucheti and Eucopia sculpticauda. Only three species were found at Wallis and Futuna Islands (cruise MUSORSTOM 7) : G. longispina, L. manilae and L. neocaledonensis. Moreover, of the 4 species identified from New Caledonia, one - Lophogaster intermedins - is a new record, bringing the total number of species known from this area to 10. From all the results published since 1981, it can be seen that 9 of the 21 lophogastrid species identified were new to science, and that the species diversity is greatest in the Philippines and Indonesia (18 species), decreasing in New Caledonia (10), and is lowest at Wallis and Futuna (3). Finally, remarks are made on the diagnostic features of each species to be retained in order to facilitate their identification.

Résumé [+] [-]The taxonomy of the crabs belonging to the family Palicidae Bouvier, 1898 from the Indo-west Pacific region is revised. On the basis of extensive material collected by French expeditions in the Coral Sea and other regions of the Pacific and Indian oceans, as well as material from numerous museums, including most of the types, the present study recognizes two subfamilies, 10 genera, and 43 species. Of these taxa, four are new genera: Exopalicus, Miropalicus, Paliculus, and Rectopalicus. Manella is synonymized with Crossotonotus A. Milne Edwards, 1873. Parapleurophricoides Nobili, 1906, sometimes believed to be a palicid, is a xanthoid and it is removed from the Palicidae. Nine nominal species described by previous authors are synonymized and an additional 17 species are described.

Résumé [+] [-]A revision of the family Trapeziidae Miers, 1886, has shown that it consists of three clades, one of which is elevated to family status, Tetraliidae fam. nov., for the genera Tetralia Dana, 1851, and Tetraloides Galil, 1986. The genera Trapezia Latreille, 1828, Calocarcinus Calman, 1909, Hexagonalia Galil, 1986, Philippicarcinus Garth & Kim, 1983, Quadrella Dana, 1851, and Sphenomerides Rathbun, 1897, remain in the Trapeziidae; Domecia Eydoux & Souleyet, 1842, Jonesius Sankarankutty, 1962, Maldivia Borradaile, 1902, Palmyria Galil & Takeda, 1986, and the fossil genus Eomaldivia Muller & Collins, 1991, in Domeciidae Ortmann, 1893. Cladistic analysis shows that Trapeziidae sensu Miers, 1886, consists of three clades that show convergence as a result of similar habits as symbionts of reef corals and other cnidarians. A list of all recognised genera and species in the three families and their primary synonyms is provided. Keys are also included for four families of Brachyura symbiotic with reef corals, and for the genera and species of Domeciidae, Tetraliidae, and Trapeziidae. Some rare colour figures are reproduced. Three name changes have resulted within the Tetraliidae: Cancer glaberrimus Herbst, 1790, for Tetralia fulva Serene, 1984, and Cancer mutus Linnaeus, 1758, for Tetralia armata Dana, 1852, and Tetralia vanninii Galil & Clark, 1988. Nomenclatural problems associated with the repeated use of "forma typica" for various species of Trapezia and Tetralia are resolved. To stabilise the nomenclature of a number of well-known species, neotypes are designated for 13 species of Trapeziidae for which type material is not extant: Trapezia cymodoce ( Herbst, 1801), and its three synonyms ( Trapezia dentifrons Latreille, 1828, Trapezia dentata var. subintegra Dana, 1852, Trapezia cymodoce var. ornatus Chen, 1933); Trapezia bidentata (Forskal, 1775), and one of its synonyms ( Trapezia ferruginea Latreille, 1828); Trapezia digitalis Latreille, 1828, and one of its synonyms ( Trapezia nigrofusca Stimpson, 1858); Trapezia septata Dana, 1852, and one of its synonyms ( Trapezia reticulata Stimpson, 1858); Trapezia areolata Dana, 1852; Trapezia bella Dana, 1852; and Trapezia speciosa Dana, 1852. Neotypes are also designated for seven species of Tetraliidae: Tetralia glaberrima ( Herbst, 1790), and three synonyms ( Trapezia integra Latreille, 1828, Trapezia serratifrons Jacquinot, 1846, Tetralia laevissima Stimpson, 1858); Tetralia muta ( Linnaeus, 1758), and one of its synonyms (Tetralia armata Dana, 1852); and Tetraloides nigrifrons ( Dana, 1852).

Résumé [+] [-]The shallow-water trapeziid and tetraliid crabs, symbionts of corals and other colonial anthozoans, from the Philippines, New Guinea, and Vanuatu are listed. A total of 13 species of Trapeziidae and six species of Tetraliidae (two new records) are listed for the Philippines, 15 Trapeziidae (four new records), six Tetraliidae (three new records) for New Guinea, and 12 Trapeziidae (six new records), four Tetraliidae (three new records) for Vanuatu. The number of species in these locations. when compared with the number in adjacent areas, does not support the view that the Indo-Malayan region or the Indo-Australian Archipelago have served as a centre of diversification for these two families.

Résumé [+] [-]Material from recent expeditions has provided an opportunity to update the revision of the Indo-West Pacific species of the families Palicidae Bouvier, 1898, and Crossotonotidae A. Milne-Edwards, 1873 (Crustacea, Brachyura, Palicoidea). A species of Neopalicus Moosa & Serène, 1981 from the Austral Islands, French Polynesia was found to be new to science. The new species can be separated from the two previously described species of Neopalicus in the morphologies of its rostrum, suborbital borders, and the abdomen and first pleopods of the male. The male of a species previously known only from the female holotype, Paliculus foliatus Castro, 2000 is also described. Six species of Palicidae and three species of Crossotonotidae are recorded for the fi rst time from the Philippines. One species of Palicidae is a new record for the Solomon Islands in the western Pacific, one species each of Palicidae and Crossotonotidae are new records for Vanuatu in the western Pacific, while 10 species of Palicidae are first-time records for Tonga in the southwestern Pacific at the extreme eastern margin of the Indo-Australian Plate.

Résumé [+] [-]The family Euryplacidae Stimpson, 1871, traditionally included in the Goneplacidae MacLeay, 1838, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of 31 species (including five that are described as new) belonging to 13 genera (including four that are described as new): Eucrate De Haan, 1835, with eight species, of which one is new; Euryplax Stimpson, 1859, with two species; Frevillea A. Milne-Edwards, 1880, with three species; Henicoplax n. gen., with five species of which three are new; Heteroplax Stimpson, 1858, monotypic; Machaerus Leach, 1818, with two species; Nancyplax Lemaitre, Garcia-Gomez, von Sternberg & Campos, 2001, monotypic; Platyozius Borradaile, 1902, monotypic; Psopheticoides Sakai, 1969, monotypic; Systroplax n. gen., monotypic; Trissoplax n. gen., with two species, of which one is new; Trizocarcinus Rathbun, 1914, with two species; Villoplax n. gen., monotypic; and Xenocrate Ng & Castro, 2007, monotypic. The genus Platyozius and Eucrate formosensis Sakai, 1974, are removed from the synonymy of Eucrate and E. alcocki Serene, in Serene & Lohavanijaya, 1973, respectively. Neotypes are selected for Heteroplax dentata Stimpson, 1858, and Pilumnoplax sulcatifrons Stimpson, 1858, two species described from Hong Kong that have a confusing taxonomic history. A neotype is also selected for Euryplax nitida Stimpson, 1859, described from the Florida Keys. Seven nominal species described by other authors were found to be junior subjective synonyms for other species: Eucrate affinis Haswell, 1882, E. costata Yang & Sun 1979, E. haswelli Campbell 1969, and Pseudorhombila sulcatifrons var. australiensis Miers, 1884, of Trissoplax dentata (Stimpson, 1858); Galene laevimanus (Lucas, in Jacquinot & Lucas, 1853) of Eucrate dorsalis (White, 1849); Heteroplax nagasakiensis Sakai, 1934, of H. transversa Stimpson, 1858; and Pilumnoplax sulcatifrons Stimpson, 1858, of Eucrate crenata (De Haan, 1835). Eight euryplacid genera are exclusively found in the Indo-West Pacific region (except one species introduced in the Mediterranean), one is exclusive to each the Eastern Atlantic and Tropical Eastern Pacific regions, three to the Western Atlantic region, and one genus has both Western Atlantic and Tropical Eastern Pacific species.

Crustaceana Monographs 17:91-104, ISBN:978-90-04-20288-7
Résumé [+] [-]A study of the goneplacid crabs (Goneplacidae) collected in the Mozambique Channel, southwestern Indian Ocean by the MAINBAZA expedition along the Mozambique coast and the MIRIKI expedition off northwestern Madagascar revealed the presence of four species, one of which is described as a new species of Pycnoplax Castro, 2007. The new species differs from its six congeners by the morphology of the carapace front, GI, and vulva, and by having a complete thoracic sternal suture 7/8. It is the first species of Pycnoplax recorded from the Indian Ocean, its congeners being restricted to the Pacific. The discovery of a new species has necessitated a review of the diagnosis of Pycnoplax and the key to its species.

Résumé [+] [-]Material, mostly deep-water, belonging to eight families of brachyuran crabs are listed from the MAINBAZA, MIRIKI, and ATIMO VATAE expeditions to the Mozambique Channel and northwestern and southern Madagascar. A new species of Ethusa Roux, 1830 (Ethusidae), unique for its vivid colouration and collection in shallow water 13-22 m deep, is described from southern Madagascar. Sphenomerides trapezoides (Wood-Mason & Alcock, 1891) (Trapeziidae) is for the first time recorded from a host, a sponge, and the presence of mucus-gathering setae are for the first time demonstrated in this rarely collected species. A neotype for Dorippe sexdentata Stimpson, 1858 (Ethusidae) is designated to stabilise the taxonomy of the species. The male and the vulva of Ethusa machaera Castro, 2005, and the vulva of E. sexdentata (Stimpson, 1858) are described for the first time. Five species are new records for Madagascar: Crossotonotus spinipes (De Man, 1888) (Crossotonotidae); Carcinoplax ischurodous (Stebbing, 1923), Goneplax clevai Guinot & Castro, 2007, and Ommatocarcinus pulcher Barnard, 1950 (Goneplacidae); and Pseudopalicus sexlobatus (Kensley, 1969) (Palicidae); while Ethusina somalica (Doflein, 1904) (Ethusidae) is a new record for the southwestern Indian Ocean.

Résumé [+] [-]Collection of 81 species belonging to 11 families of six superfamilies of brachyuran crabs are reported from expeditions in Papua New Guinea (BIOPAPUA (2010), PAPUA NIUGINI (2012), MADEEP (2014), and KAVIENG 2014 (2014) cruises). The species, belonging to Dorippoidea (Ethusidae), Goneplacoidea (Goneplacidae, Euryplacidae, Progeryonidae), Homoloidea (Latreilliidae), Palicoidea (Crossotonotidae, Palicidae), Pilumnoidea (Pilumnidae Eumedoninae) and Trapezioidea (Domeciidae, Tetraliidae, Trapeziidae) were mostly collected from deep water and are rarely collected and studied. Fifty species are recorded from the island of New Guinea for the first time. Ethusina ocellata Castro, 2005 (Ethusidae) was found to be a junior subjective synonym of Ethusina microspina Chen, 2000, and Ethusa crassipodia Castro, 2005 (Ethusidae) of Ethusa curvipes Chen, 1993. Ethusina exophthalma Castro, 2005 is reassigned to Ethusa Smith, 1884, as Ethusa exophthalma (Castro, 2005) n. comb. The females of Parethusa hylophora Castro, 2005 (Ethusidae) and Thyraplax digitodentata Castro, 2007 (Goneplacidae), respectively, are described for the first time. A neotype is designated for Trapezia rubridactyla Garth, 1971 (Trapeziidae). Color photographs of fresh material of many of the species are published for the first time.

Résumé [+] [-]A reappraisal of the taxonomy of the brachyuran crabs belonging to the family Goneplacidae MacLeay, 1838 sensu lato has resulted in the revision of the subfamily Goneplacinae, which combines the subfamilies Goneplacinae MacLeay, 1838 and Carcinoplacinae H. Milne Edwards, 1852. Most of the 66 species of Goneplacinae sensu stricto that are listed herein inhabit relatively deep water and are infrequently collected. The subfamily Goneplacinae sensu stricto now consists of 17 genera of which 10 are being described as new: Carcinoplax H. Milne Edwards, 1852, with 18 species of which four are new; Entricoplax n. gen., monotypic; Exopheticus n. gen., with two species; Goneplacoides n. gen., monotypic; Goneplax Leach, 1814, with four species; Hadroplax n. gen., monotypic; Menoplax n. gen., monotypic; Microgoneplax n. gen., with five species of which four are new; Neogoneplax n. gen., with three species of which two are new; Neommatocarcinus Takeda & Miyake, 1969, monotypic; Notonyx A. Milne-Edwards, 1873, with three species; Ommatocarcinus White, 1852, with four species; Paragoneplax n. gen., monotypic; Psopheticus Wood-Mason, 1892, with four species; Pycnoplax n. gen., with five species of which one is new; Singhaplax Serene & Soh, 1976, with seven species of which four are new; and Thyraplax n. gen., with five species of which three are new. All goneplacine genera are exclusive to the Indo-West Pacific region (plus contiguous temperate areas) except Goneplax, which is so far known mostly from the Atlantic and Mediterranean regions. Four nominal species described by other authors were found to be junior subjective synonyms for other species: Carcinoplax verdensis Rathbun, 1914 and C polita Guinot, 1989 synonymous of C specularis Rathbun, 1914; Goneplax megalops Komatsu & Takeda, 2003 of Goneplacoides marivenae (Komatsu & Takeda, 2003) n. comb.; and Psopheticus insolitus Guinot, 1990 of P stridulans Wood-Mason, 1892.

Résumé [+] [-]Two new species belonging to the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) are described from the western Pacific Ocean. The first belongs to Carcinoplax H. Milne Edwards, 1852, the second to Pycnoplax Castro, 2007. The new species of Corcinoplax is distinguished from the 18 known species of the genus by the morphologies of the first male pleopods and outer orbital and anterolateral teeth; the new species of Pycnoplax is distinguished from the five known species of the genus by the morphology of the first and second male pleopods and the granular carapace. A female specimen of a third goneplacid, Thyraplax truncata Castro, 2007, which was previously known only from male specimens, is also described. The characters of the two new species further confirm that in the Goneplacidae s.s. the morphology of the external reproductive structures rather than that of the carapace are far more reliable in showing phylogenetic relationships among supraspecific taxa.

Résumé [+] [-]Naked goose neck barnacles Conchoderma can grow on a wide variety of marine organisms. The taxonomic status of two of its species—C. virgatum and C. hunteri—are currently controversial. Some studies suggest that C. hunteri is a subspecies, variety or growth forms of C. virgatum, because both have great morphological variations, but other studies consider C. hunteri and C. virgatum to be distinct species. The present study examines the morphology and sequence divergence of the COI gene in C. virgatum, C. hunteri and other closely related species. There are consistent morphological differences between C. virgatum and C. hunteri in the tergum, carina and fifth teeth of the mandible. Phylogenetic analysis based on the divergence in the COI gene revealed that C. virgatum and C. hunteri form sister clades with high bootstrap values. The K2P distances within C. hunteri and C. virgatum are 0.034 ± 0.008 and 0.002 ± 0.001 for the COI sequences, respectively. The K2P distance between C. hunteri and C. virgatum is 0.097 ± 0.016. Morphological and molecular evidence confirm that C. hunteri is a valid species.

Résumé [+] [-]Taiwan is a large island in north western Pacific waters with the sea floor connecting to two major deep-sea basins, the eastern waters facing the Pacific Ocean (to 4000 m depth) and linking to the Philippine Basin, whilst south western waters are associated with the South China Sea Basin (up to 1000 m). Previously, the biodiversity of Taiwanese deep-sea barnacles had not been studied extensively, due to a lack of deep-sea expeditions and sampling. Recently, several TAIWAN deep-sea cruises investigated the biodiversity of the deep-sea fauna of Taiwan and sampling was conducted to depths of 4000 m. The present study reports on the biodiversity of the deep-sea barnacles of Taiwan, a total of 18 species. One species was previously recorded from Taiwanese waters and 17 are new records, including two new species belong to the genera Litoscalpellum and Altiverruca.

Résumé [+] [-]Cirripedes of the superorder Acrothoracica are normally found as epizoic borings on marine calcareous substrates. Armatoglyptes taiwanus (Utinomi, 1950) is a lithoglyptid acrothoracican barnacle reported from different parts of the Indo-Pacific. Recent studies have demonstrated phylogenetic breaks between the Indian and Pacific Oceans populations in widespread Indo-Pacific marine organisms due to isolation events during the Pleistocene glaciations. It is possible that A. taiwanus represents a cryptic species complex in the Indo-Pacific, which the previous studies have failed to identify from morphology alone. In the present study, we analyzed the morphology and the sequence divergence of the 12S rDNA of A. taiwanus from the Indo-Pacific region, including Taiwan and the Philippines in the Pacific, and Phuket Island (Thailand) and the Mozambique Channel in the Indian Ocean, to test whetherA. taiwanus is a cryptic species across its geographical range. The results showed that A. taiwanus has a homogeneous population structure in Taiwan, the Philippines, and Phuket Island (sequence divergence < 1%). Specimens from the Mozambique Channel, although morphologically similar to A. taiwanus, have a greater sequence divergence of 9.4% from A. taiwanus in the Pacific, and thus appeared to represent a new species, described herein as Armatoglyptes flexuosus n. sp. Although both species are morphologically similar, A. flexuosus n. sp. has more strongly bent/recurved posterior processes of the opercular bars and feebler armament of the orificial knob than does A. taiwanus from Taiwan (type locality). Phylogenetic analysis showed that populations of A. flexuosus n. sp. from the Mozambique Channel and A. taiwanus from the Pacific region are indeed closely related. Populations of their common ancestor may have become isolated and underwent speciation during the Pleistocene glaciations.

Mémoires du Muséum national d'Histoire naturelle 204:67-84, ISBN:978-2-85653-692-6
Résumé [+] [-]Two new Oxynaspis species associated with antipatharian corals are described from the AURORA expedition in the Philippines and from Taiwan waters. Oxynaspis auroraensis n. sp. was collected from the Philippines at more than 500 m depth and belongs to the fully armored group of Oxynaspis. The umbo of the carina of O. auroraensis n. sp. is located in a proximal position with the carinal distal arm about 3.5 times longer than the basal arm. Such a position is diagnostic, distinguishing this species from all previously described Oxynaspis species. Oxynaspis biradius n. sp. was collected from Taiwanese waters at 20-30 m depth and belongs to the reduced scutum group of Oxynaspis. The morphology of O. biradius n. sp. is close to that of O. joankovenae Van Syoc & Delkelboum, 2011, but differs in having two distinct white rays on the scutum and a more pointed tergal spur. From molecular analysis in the sequence divergence of the 12S and COI region, O. auroraensis n. sp. and O. biradius n. sp. form distinct monophyletic clades and the interspecific divergence suggests that these two species are distinct.

Zootaxa 3866(2): 261-276. DOI:10.11646/zootaxa.3866.2.5
Résumé [+] [-]The present study describes a new species of Arcoscalpellum Hoek, 1907, and a new species of Gymnoscalpellum Newman & Ross, 1971, collected by deep-sea expeditions led by the Muséum national d’Histoire naturelle (Paris) in the Coral Sea off New Caledonia, Papua New Guinea (PNG), the Solomon Islands and Vanuatu. Arcoscalpellum epeeum sp. Nov. Differs from all described species of Arcoscalpellum by the presence of a long, sharp, sword-shaped carina, which extends beyond the apices of the terga by 1/3 to 1/4 of their length. The species is dioecious, with large females and dwarf males that are sac-like, lack shell plates and are housed in paired receptacles at the inner edges of the scutal plates. Arcoscalpellum epeeum sp. Nov. Was collected in the waters of New Caledonia and Vanuatu. Gymnoscalpellum indopacificum sp. Nov. Differs from the six currently described species of Gymnoscalpellum by having a very small inframedian latus and a branched upper latus. The species is dioecious, with large females and dwarf males, the latter composed of 4 shell plates and housed in paired receptacles at the inner edges of the scutal plates. The penis of the dwarf males of G. indopacificum sp. Nov. Is about 0.8 of the total length of the male and has five side branches extending out along its length. Gymnoscalpellum indopacificum sp. Nov. Is distributed in the waters of Papua New Guinea, the Solomon Islands and Vanuatu, and represents the first record of this genus in the Indo-Pacific region.

Chan B.K. & Rodriguez moreno P.A. 2020. A new deep-sea barnacle, Calantica australpacifica sp. nov. (Scalpelliforms: Calanticidae) in the South Pacific: first report on the presences of dwarf males on the sub-rostral position in Calantica, Deep-Sea Crustaceans from Papua New Guinea - Tropical Deep-Sea Benthos 31. Mémoires du Muséum national d'histoire naturelle Tome 213. Publications scientifiques du Muséum national d'histoire naturelle, Paris:445-460, ISBN:978-2-85653-913-2
Résumé [+] [-]The present study identified a new Calantica species from the deep-sea of the Papua New Guinea. Calantica australpacifica sp. nov. has 13 capitular plates (S-T surrounded by R-RL-L-CL-C-SC) and these plates are arranged in two horizontal whorls and with small degree of plate overlapping in the large hermaphrodites. There are some hermaphroditic individuals have asymmetrical plate arrangement, with additional CL and L on one side. Sexual system of C. australpacifica sp. nov. is androdieocy, with large hermaphrodite being accompanied by dwarf males (with well-developed penis but absences of ovarian tissue) that are often located on the sub-rostral position of the peduncle. Dwarf males are differentiated into peduncle and capitulum. Lateral side of the basal portion of dwarf male peduncle attached to the large hermaphrodite, result in one lateral side of the dwarf male facing the hermaphrodite and vice versa. Capitulum of dwarf males with asymmetrical plate arrangement. The lateral side of dwarf males opposing away from the hermaphrodite has S-T surrounded by R-RL-L-CL-C-SC and the lateral side facing the hermaphrodite composed of S-T, without RL, L and CL. This is the first report on the location of dwarf males on sub-rostral position in Calantica, rather than in the supra-oral position within the capitulum. Morphology of C. australpacifica cannot be assigned to the present 4 morphological groups of Calantica and represent a new group and new species.

Mémoires du Muséum national d'Histoire naturelle 168:269-336, ISBN:2-85653-501-1
Résumé [+] [-]The species of Pontocaris Bate, 1888, and related genera, Aegaeon Agassiz, 1846 and Parapontocaris Alcock, 1901, are reviewed based on the abundant samples collected by ORSTOM (Institut français de Recherche scientifique pour le Développement en Coopération), the Muséum national d'Histoire naturelle, the Forschungsinstitut Senckenberg, and the National Taiwan Ocean University, as well as those deposited at other museums and institutions. Altogether 21 species and one subspecies are recognized which appear to form three natural groups. The genus Parapontocaris Alcock, 1901 is retained for the 6 species assigned to it by CHACE (1984), but different characters are used to differentiate them. An interlocking mechanism between the posterior thoracic sternites and the carapace is found in all species of the Pontocaris propensalata group, but not in the others. Furthermore, females of this group can modify their pereiopods, probably for the care of the eggs, when they molt for spawning. Such modification of the pereiopods is unique in the carideans according to present knowledge. Thus, the genus Pontocaris Bate, 1888, is now restricted to the species of this group and BRUCE'S (1988) Pontocheras becomes a junior synonym of the former. At present 10 species and one subspecies are recognized in this group, with the names P. affinis (Alcock, 1901) and P. hilarula (de Man, 1918) revived and four new species and one new subspecies described : P. major from the Philippines, P. laurentae and P. spinifera from Indonesia, P. profundior from the Red Sea and Gulf of Aden, and P. affinis allodactylus from the Red Sea. The name Aegaeon Agassiz, 1846 is revived for five species with characters intermediate between Parapontocaris and Pontocaris (as defined here), namely A. cataphractus (Olivi, 1792), A. lacazei (Gourret, 1887), A. orientalis Henderson, 1893, A. rathbuni de Man, 1918 and A. boschii (Christoffersen, 1988). Keys for distinguishing these three genera and the identification of the species are provided. The distribution and evolution, as well as sexual dimorphism and polymorphism in females, of these species are briefly discussed. Both the morphological characters and distribution patterns suggest that the genus Parapontocaris is relatively more ancient and has a typical Tethys distribution. On the other hand, species of Pontocaris possess many advanced characters and are still actively evolving in the Indo-West Pacific. The intermediate genus Aegaeon probably forms a link between the above two genera and has successfully invaded the Atlantic from the original Indo-West Pacific distribution.

Résumé [+] [-]The KARUBAR cruise in 1991 collected a number of deep-sea lobster specimens from Indonesia. The material is found to contain five species of palinurids, five species of scyllarids and 11 species of nephropids. Although no new species were found, the KARUBAR material extends the known distributions for many species, such as Linuparus trigonus (von Siebold, 1824), Palinustus unicornutus Berry, 1979, lbacus pubescens Holthuis, 1960, I. novemdentatus Gibbes, 1850, Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993,N. serrata Macpherson, 1993, N. stewarti Wood-Mason, 1872, N. sulcata Macpherson, 1990, and Metanephrops australiensis (Bruce, 1966). The most interesting finding is a complete specimen of Metanephrops arafurensis (de Man, 1905), which was previously known only from a mutilated type. Together with the additional knowledge gained of the characteristics of the other Metanephrops species, their relationships are discussed and a revised key to the species of this genus is provided.

Résumé [+] [-]Abundant material of the rare lobster genus Thaumastocheles, recently collected from Taiwan, led to an extensive survey of the Indo-Pacific specimens of this genus deposited at various institutions. Altogether 82 specimes of Thaumastocheles from the Indo-Pacific (Madagascar to Japan and New Caledonia at depths of 70-1,753 m) were examined and 2 distinct species are recognized. The 2 species, T. japonicus Calman, 1913, and T dochmiodon, new species, differ mainly in the shape of the cutting teeth of the first chelae and the lateral carinae of the abdominal tergites. Both species are found in Japan, Taiwan, and the South China Sea.

Résumé [+] [-]A phylogenetic analysis of all 17 extant species of the clawed lobster genus Metanephrops based on mitochondrial 12S rRNA, 16S rRNA and cytochrome c oxidase 1, and nuclear histone H3 gene sequences supports the morphological groupings of two of the traditional groups of the genus (the binghami and japonicus groups) but refutes monophyly of the other two groups (the arafurensis and thomsoni groups). The results in general support a recent morphology-based cladistic analysis of this genus except that this study suggests M. neptunus to be a basal rather than a derived species as indicated in the morphological analysis. This species is genetically diverse over its geographical range. Moreover, the two color forms of M. thomsoni are genetically distinct, most likely representing different species. The molecular phylogeny and current distribution pattern of the extant species, together with the fossil record. suggest that the genus originated in the Antarctica in the Cretaceous, followed by diversification and dispersal along the continental shelf of different continents as a result of the vicariant events associated with the breakup of the Southern Temperate Gondwana since Late Cretaceous.

Résumé [+] [-]Molecular phylogenetic analysis on nine of the ten genera in the caridean family Oplophoridae Dana, 1852, as well as 14 other caridean families using mitochondrial 16S and nuclear 18S rRNA genes, does not support the monophyletic status of Oplophoridae. Two disparate groups of oplophorids are revealed, with different morphological characters and ecology. It is proposed that the family Oplophoridae is restricted to the three genera Oplophorus, Systellaspis and Janicella. These three genera tend to be distributed in shallower water than the other oplophorid genera, and can also be distinguished from them by certain morphological characters. They have a thicker integument, superficial cuticular photophores and larger eyes, and the molar process of their mandibles is greatly reduced or bears a deep channel. The family Acanthephyridae Bate, 1888 is resurrected for the other seven genera, which are generally distributed in deeper water and are characterised by red soft integument, no cuticular photophores, smaller eyes and well-developed molar process of the mandibles without a deep channel. The relationships between these two families and other caridean families could not be clearly resolved in this study.

Résumé [+] [-]The availability of abundant fresh material of Aristeus alcocki Ramadan, 1938 from India allowed the evaluation of the variation in the numbers of photophores on the pereiopods in this species, as well as other diagnostic characters for species discrimination. Although the pereiopodal photophore counts in A. alcocki largely overlap with those of A. semidentatus Bate, 1888, it is found that A. alcocki is unique in the Indo-West Pacific species of the genus by the lower end of the cervical carina considerably farther away from the branchiostegal carina. Molecular genetic analysis confirmed the distinct taxonomic status of the six currently known species in this genus from the Indo-West Pacific and a revised key is provided for distinguishing them.

Résumé [+] [-]The availability of Indian specimens of Plesionika persica (Kemp, 1925) and P. reflexa Chace, 1985 provided more information on the taxonomy around these two species. Moreover, it is the first record of P. persica to India. Although P. taiwanica Chan and Yu, 2000 is superficially rather similar to P. persica, there are many differences between them and probably it is inappropriate to establish a species group for these two species. It is likely that all previous records of P. ensis (A. Milne-Edwards, 1881) from India actually represent P. reflexa Chace, 1985. Nevertheless, the present Indian specimens of P. reflexa have more than 10% COI sequence divergence from the topotypic materials of both P. ensis and P. reflexa, and the epipods at the pereiopods III and IV reduced or absent. This data further highlights the confusing taxonomy in the “P. ensis” group.

Résumé [+] [-]Samples collected by ORSTOM (Institut de Recherche Scientifique pour le Developpement en Cooperation), Service Mixte de Contrôle Biologique des Armees (SMCB) and the National Taiwan Ocean University in the Indo-West Pacific (off Madagascar, Seychelles Islands, Taiwan, Philippines, Indonesia, Chesterfield Islands, New Caledonia and Polynesia) as well as others obtained on loan from various museums led to a reexamination of the species belonging to the Plesionika narval group. Fourteen species are recognized of which 6 are new : P. yui from Taiwan, P. echinicola from New Caledonia, P. laurentae from New Caledonia and Eastern Australia, P. flavicauda from New Caledonia and Polynesia, P. rubrior and P. curvata from Polynesia. P. escalilis (Stimpson, 1860) is considered to be a synonym of P. narval. The specimens from the Atlantic identified as STIMPSON'S species by LEMAITRE and GORE (1988) are identified as P. longicauda (Rathbun, 1901). P. narval and P. serratifrons (Borradaile, 1900) are considered as distinct species but so similar that finding reliable characters to separate them is very difficult especially as individual variations are observed. P. narval is presently regarded as living only in the Mediterranean and Eastern Atlantic (from Spain to Cape Verde Islands) but it appears South-West Pacific and with a rather restricted distribution. A key mainly for adults is offered for the identification of the species of this group. As coloration very often seems to be a reliable character for identifying fresh specimens, color photographs are included. Unfortunately it was not possible to obtain information on the coloration of all the species and consequently this character could only be used rarely in the key.

Résumé [+] [-]A new shrimp species of the genus Plesionika Bate, 1888 is described based on specimens collected in deep-water off eastern Taiwan. The new species, P. albocristata, can be readily distinguished from other species of the genus by bearing a high basal rostral crest, having the second pereiopods subequal, and the telson bearing four pairs of dorsolateral spines. A brief discussion on the affinities of this new species is given.

Mémoires du Muséum national d'Histoire naturelle 191:293-318, ISBN:2-85653-557-7
Résumé [+] [-]Before the present study, Plesionika rostricrescentis (Bate, 1888) and P. lophotes Chace, 1985 were the two Plesionika species unique in having a high basal rostral crest. A recently described species, P. erythrocyclus Chan & Crosnier, 1997 has a low basal rostral crest but is evidently related to P. rostricrescentis. Close examination of the abundant material collected during the MUSORSTOM expeditions and from Taiwan revealed that there are at least eight species in this ‘‘P. rostricrescentis-P. lophotes’’ species complex. These taxa are morphologically very similar but can be distinguished by their very distinctive colorations, which are often striking and consist of large circular spots. In the ‘‘P. rostricrescentis’’ group, which has the dorsal margin of the rostrum unarmed between the anteriormost tooth of the basal rostral crest and the subapical teeth, five species are recognized. Plesionika rostricrescentis is still known only by the holotype from the Kai Islands. Two new species, P. hsuehyui and P. suffusa, closely similar to P. rostricrescentis, are described. Plesionika hsuehyui is widely distributed from Taiwan to Fiji, while P. suffusa has only been found off New Caledonia. Plesionika erythrocyclus, previously known only from Taiwan and French Polynesia, occurs widely in the southern Pacific. Another new species, P. bimaculata, which closely resembles P. erythrocyclus, is distributed off New Caledonia and in adjacent areas. Three species are recognized in the ‘‘P. lophotes’’ group, which bear dorsal rostral teeth between the basal rostral crest and subapical teeth. Plesionika lophotes is restricted to the area between Japan and northwestern Australia. Two further closely similar new species, P. rufomaculata and P. scopifera are described, the former widely distributed from Okinawa to Futuna Island, the latter only off New Caledonia and Tonga. Although coloration is very important in distinguishing these species, species with similar color patterns do not necessarily belong to the same species group. Morphologically, these species are mainly separated by the height of the basal rostral crest, the number of rostral teeth, and the length of the stylocerite and the dactyli of the posterior three pereiopods. However, there is sexual dimorphism in the development of the basal rostral crest in these species, sometimes making positive identification of males and young specimens difficult.

Mémoires du Muséum national d'Histoire naturelle 204:191-230, ISBN:978-2-85653-692-6
Résumé [+] [-]Recent French deep-sea expeditions in the Indo-West Pacific resulted in the collection of abundant material of the deep-sea lobster genus Puerulus Ortmann, 1897 (Palinuridae). Difficulties in identification necessitated a generic revision and as a result, five new species are described, all of which are similar to P. angulatus (Bate, 1888). Puerulus angulatus was thought to have a wide distribution from eastern Africa to Marquesas Islands, but is now restricted to the western Pacific, from Japan to Australia. Of the five new species, P. gibbosus n. sp. is found in eastern Africa, P. mesodontus n. sp. from Japan to Fiji, P. richeri n. sp. from the New Caledonia to Marquesas Islands, while P. sericus n. sp. and P. quadridentis n. sp. mainly occur around New Caledonia. Of the other three previously described species, the distribution of P. velutinus Holthuis, 1963, is extended to Fiji, while P. sewelli Ramadan, 1938, and P. carinatus Borradaile, 1910, are still only known from the northern and western parts of the Indian Ocean, respectively. COI gene sequence differences support the morphological species distinctions.

Résumé [+] [-]Specimens of species closely related to the rare deep-sea lobster Thaumastocheles japonicus Calman, 1913 were obtained from recent deep-sea expeditions in the West Pacific. Close examination of these specimens, as well as molecular analysis, showed that they represent two species new to science, with many morphological and significant genetic differences (barcoding gene COI sequence divergences 11.5- 14.8%) between each other as well as T. japonicus. Re-examination of the specimens previously assigned to T. japonicus revealed that true T. japonicus has a more northern distribution, from Japan to the South China Sea and the Philippines. The two new species have more southern distributions with T. bipristis n. sp. Restricted to the Philippines and Indonesia, and T. massonktenos n. sp. Being widely distributed in the Indo-West Pacific, from the South China Sea to Madagascar and New Caledonia. The genetic data also suggest that T. dochmiodon Chan and de Saint Laurent, 1999 may represent a polymorphic male form of T. japonicus.

Résumé [+] [-]The rare deep-sea lobsters of the genus Thaumastocheles Wood-Mason, 1874 are characterized by having conspicuously unequal first chelipeds, with the right cheliped greatly elongated and pectinate. The five species of Thaumastocheles are mainly separated by the shape of the teeth in the major chelae. Molecular analysis using four genetic markers (three mitochondrial: COI, 12S rDNA, 16S rDNA; one nuclear: ITS-1) on an extensive series of the species of Thaumastocheles from different localities reveals that there is sexual dimorphism and even male polymorphism in the major chelae in at least half of the species, with T. dochmiodon Chan & de Saint Laurent, 1999 being the male form in T. japonicus Calman, 1913. Thaumastocheles dochmiodon is therefore considered a junior synonym of T. japonicus. The other species confirmed as showing sexual dimorphism and male polymorphism is T. massonktenos Chang, Chan & Ahyong, 2014. A revised key is provided for the species of Thaumastocheles. Whether sexual dimorphism and male polymorphism are common phenomena in Thaumastocheles or even all thaumastocheliforms still awaits the collection and discovery of additional material of both sexes.

Résumé [+] [-]Recent deep-sea cruises using Taiwanese research vessels off Taiwan and in the South China Sea yielded seven species of the clawed lobster genus Nephropsis Wood-Mason, 1872. Four species are new records for Taiwan (Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993, N. serrata Macpherson, 1993, and N. suhmi Bate, 1888) and three species are new records of Dongsha (under the jurisdiction of Taiwan) in the South China Sea (N. ensirostris Alcock, 1901, N. stewarti Wood-Mason, 1872, and N. suhmi). Altogether, five and four species of this genus are now known from Taiwan and Dongsha, respectively. The diagnostic characters and coloration are illustrated for most, if not all, of these species.

Résumé [+] [-]Nephropsis stewarti Wood-Mason, 1872 is the most common species of the deep-sea clawed lobster genus Nephropsis Wood-Mason, 1872 in the Indo-West Pacific. Morphological comparisons and genetic analyses of extensive material referred to this lobster revealed the presence of three species. The three species differ mainly in body size, development of the intermediate carina on the carapace, position of the lateral pair of rostral teeth, whether the pleonal tergum is granulate, and the spination on the large chelipeds. Nephropsis stewarti is restricted to the western central Indian Ocean, and a neotype is selected to fix its identity. The name Nephropsis grandis Zarenkov, 2006 is revived with neotype selection for the large form found in the West Pacific and northwestern Australia. The smaller form from southern Taiwan and the Philippines is described as Nephropsis pygmaea sp. nov.

Résumé [+] [-]The Oxfordian fauna from the Terrain à Chailles Formation, eastern France (Haute- Saône, Franche-Comté) is remarkable for its exceptionally preserved crustaceans found in siliceous concretions locally named “chailles”. The crustacean fauna includes 9 different species assigned to the Glypheidae, the Erymidae, the Eryonidae and the Axiidae. Glypheid and erymid lobsters are the most diversified groups with four and three different species respectively. Re-examination of numerous new specimens allows to a more modern and more complete characterization of Glyphea regleyana (Desmarest, 1822), Glyphea muensteri von Meyer, 1840 and Eryma ventrosa (von Meyer, 1835). New detailed anatomic descriptions of these species highlight the presence of marked sexual dimorphism in G. regleyana and probably in E. ventrosa. They reveal processes of autotomy and phenomena of ecdysis in G. regleyana, E. ventrosa and G. muensteri. Quantitative analyses based on 424 nodules show three dominant species: 1) Glyphea regleyana (50.5% of nodules); 2) Eryma ventrosa (24.8%); and 3) Glyphea muensteri (16.5%).Convergent lines of evidence from depositional environment, comparisons with others Jurassic crustaceans and modern analogues indicate that the crustacean fauna from the Terrain à Chailles Formation probably inhabited a moderately deep water setting most probably about 100-150 m (lower circalittoral zone) where light intensity was even sensitive. These crustaceans constitute a very original assemblage intermediary between the communities from the shallow carbonate platforms (e.g., Solnhofen) and those from the bathyal zone (e.g., La Voulte). This new set of data sheds new light on the colonization of the distal platforms by crustacean communities in the Mesozoic.

Résumé [+] [-]A phylogenetic analysis of a total of 31 species: 27 fossil species from seven families (Glypheidae, Litogastridae, Mecochiridae, Pemphicidae, Erymidae, Clytiopsidae, Chimaerastacidae), and four extant species from three families (Glypheidae, Nephropidae, Stenopodidae) is proposed. Most of the genera considered are coded exclusively based upon their type species and, as much as possible, based upon the type specimens. The cladistic analysis demonstrates that the glypheidean lobsters (infraorder Glypheidea) form a monophyletic group including two superfamilies: Glypheoidea and Pemphicoidea new status. Glypheoidea includes three families: Glypheidae, Mecochiridae and Litogastridae. Litogastridae is the sister group of the clade Glypheidae + Mecochiridae. Pemphicoidea includes a single family: Pemphicidae. A new classification of Glypheidea is proposed and currently known genera are rearranged based upon the phylogenetic analysis.

Phylogeny of Stenopodidea (Crustacea : Decapoda) shrimps inferred from nuclear and mitochondrial genes reveals non-monophyly of the families Spongicolidae and Stenopididae and most of their composite genera. Invertebrate Systematics 30(5): 479-490. DOI:10.1071/IS16024
Résumé [+] [-]The infraorder Stenopodidea is a relatively small group of marine decapod crustaceans including the well known cleaner shrimps, but their higher taxonomy has been rather controversial. This study provides the most comprehensive molecular phylogenetic analyses of Stenopodidea using sequence data from two mitochondrial (16S and 12S rRNA) and two nuclear (histone H3 and sodium–potassium ATPase a-subunit (NaK)) genes. We included all 12 nominal genera from the three stenopodidean families in order to test the proposed evolutionary hypothesis and taxonomic scheme of the group. The inferred phylogeny did not support the familial ranking of Macromaxillocarididae and rejected the reciprocal monophyly of Spongicolidae and Stenopididae. The genera Stenopus, Richardina, Spongiocaris, Odontozona, Spongicola and Spongicoloides are showed to be poly- or paraphyletic, with monophyly of only the latter three genera strongly rejected in the analysis. The present results only strongly support the monophyly of Microprosthema and suggest that Paraspongiola should be synonymised with Spongicola. The three remaining genera, Engystenopus, Juxtastenopus and Globospongicola, may need to be expanded to include species from other genera if their statuses are maintained. All findings suggest that the morphological characters currently adopted to define genera are mostly invalid and substantial taxonomic revisions are required. As the intergeneric relationships were largely unresolved in the present attempt, the hypothesis of evolution of deep-sea sponge-associated taxa from shallow-water free-living species could not be verified here. The present molecular phylogeny, nevertheless, provides some support that stenopoididean shrimps colonised the deep sea in multiple circumstances.

Résumé [+] [-]Numerous samples of Stylodactylidae collected between 1976 and 1989 off the Philippines, New Caledonia and Chesterfield Islands (MUSORSTOM, BIOCAL, CHALCAL, CORAIL 2 a n d SMIB cruises) are studied here. Other collections from Indonesia (CORINDON 2 cruise), Madagascar (coll. A. CROSNIER and R. CLEVA), and la Réunion (« MARION DUFRESNE », cruise M D 32) are included. This material is of particular interest since many specimens of various taxa have been collected : eighteen species and subspecies have been identified in it, of which nine are new : three species and one subspecies in the genus Stylodactylus. four species in the genus Parastylodactylus, and one in the new genus Stylodactyloides. Nine species and one subspecies of the genus Stylodactylus A. Milne Edwards, 1881., are represented in the collections studied here. S. laurentae sp. nov., with its typically short rostrum, seems to be one of the most common shrimps of the genus in New Caledonia and Chesterfield Islands. S. profundus sp. nov., unfortunately represented by specimens in incomplete or poor condition, extends the bathymetric range of the family : it has been collected, off New Caledonia, between 1395-1410 and 1618-1740 m. S. brevidactylus sp. nov. is represented by a single specimen from the Philippines : we at first considered that this specimen was an aberrant example of S. multidentatus Kubo, 1942, but decided then to re-examine our opinion because of its peculiar characters. Twenty seven specimens (eleven from the Philippines and sixteen from Chesterfield Islands and New Caledonia) have been identified as S. licinus Chace, 1983, a little known species described from the Philippines, and eleven others (one from Indonesia and ten from New Caledonia and Chesterfield Islands) as S. tokarensis Zarenkov, 1968, only known by the holotype collected in the east China sea (the paratype of S. tokarensis is suspected of being a specimen of S. licinus Chace). S. multidentatus Kubo, 1942, is probably one of the most commonly caught species of the family. Many specimens have been collected by the french campaigns from the Philippines, New Caledonia, and Madagascar : Neocaledonian specimens differ from the former by a longer rostrum and longer spines on the margin of the antennal scale. These differences are still more accentuated in Madagascarian specimens, and we finally decided to create for them a new subspecies, S. multidentatus robustus. Two other species of Stylodactylus are represented in our material : S. macropus Chace, 1983, of which the only previouly known specimen was collected by the « ALBATROSS » in the Philippines, is reported here, again from the Philippines and from New Caledonia and Chesterfield Islands. S. libratus Chace, 1983, described from a single specimen from Indonesia (Celebes, « ALBATROSS » collection) and reported then from Australia (New South Wales) by KENSLEY, TRANTER and GRIFFIN (1987) has been collected in New Caledonia and Chesterfield Islands. One specimen from Madagascar appears to be very close to S. libratus but shows however some différences from it, so that we identify it as S. aff. libratus. The genus Neostylodactylus Hayashi & Miyake, 1968, is represented in our material by two species : N. amarynthis (de Man, 1902), and N. affinis Hayashi & Miyake, 1968 : in these two species we have noted the very particular sexual dimorphism mentioned by CHACE (1983 : 6) for N. amarynthis : females differ from maies in lacking arthrobranchs on pereiopods 1 to 4. The geographical distribution of N. amarynthis extends now, in the Indo-Pacific, to the southwestern Indian Océan (La Réunion), and that of N. affinis, previously known only from the Korea Strait at 120 m depth, is shown to belong to the New Caledonia and Chesterfield Islands fauna ; it has been caught between 235 and 440 m. Four new species have been included in the genus Parastylodactylus created by FIGUEIRA in 1971 for Stylodactylus bimaxillaris Bate, 1888, and until now monospecific. P. bimaxillaris (Bate), known from a large part of the Indo-Pacific, is mentioned for the first time from New Caledonia and Madagascar. P. tranterae sp. nov., collected off New Caledonia and Chesterfield Islands, was first reported from Australia (New South Wales) by KENSLEY, TRANTER a n d GRIFFIN (1987) who suspected that it was a new species, butdid not name it, on account of the poor condition of the single specimen in their possession. P. semblatae sp. nov. seems to be very common in New Caledonia and Chesterfield Islands. P. richeri sp. nov., from New Caledonia, and P. longidactylus sp. nov., from the Philippines, each represented by a few specimens only, are fairly closely related species, but however are clearly distinct taxa. A new genus, Stylodactyloides, is proposed for a new species collected from New Caledonia and Chesterfield Islands, 5. crosnieri, which has a very unusual stylocerite, broadly rounded distally, which distinguishes it from ail other members of the family. It may be noted that several points in the systematics of the Stylodactylidae remain obscure. These will necessitate the examination of new collections. This work, however, shows the particular interest of these collection, concerning a little known and poorly represented family (nine new taxa described, representing more than one third of the species known until now), and indicates the richness of New Caledonia and Chesterfield Islands waters, where thirteen species have been collected, including six of the nine new ones. Ail the new taxa have been illustrated, and individual variations carefully studied in the species represented by numerous specimens. Color photographs of several species, taken on board during some of these cruises, complété the iconography. Identification keys are proposed for the four généra and twenty six species and subspecies now recognized in the family.

Résumé [+] [-]During the French-Indonesian expedition KARUBAR off Kai and Tanimbar Islands (Moluccas) in 1991, eight species of Stylodactylidae were collected. One of these species, Parastylodactylus moluccensis was new. Two other species, Parastylodactylus richeri Cleva, 1990, and Neostylodactylus affinis Hayashi & Miyake, 1968, are recorded from the region for the first time and the remaining five species, Stylodactylus tokarensis Zarenkov, 1968, S. multidentatus Kubo, 1942, S. libratus Chace, 1983, Parastylodactylus bimaxillaris (Bate, 1888), and Stylodactylus licinus Chace, 1983, are already known from the Indonesian area, the last one having been recorded recently by TAKEDA and HANAMURA (1994). On the other hand, some specimens, at first identified doubtfully as Stylodactylus libratus, and related to Stylodactylus pubescens Burukovsky, 1990, have been causing trouble to us, and we have not find till now a satisfying solution: they are mentionned here as Stylodactylus sp. Stylodactylus brevidactylus Cleva, 1990, considering the variability observed through 49 specimens of S. multidentatus Kubo collected during this cruise, is synonymised with this species. We added to the indonesian material, for each different species, the specimens collected recently from Wallis and Futuna, the Vanuatu and New-Caledonia. The species from these three countries which have not been collected during the KARUBAR expedition are mentionned at the end of this study.

Résumé [+] [-]Twenty nine specimens of the rare deep-sea shrimps Bathypalaemonellidae, just represented until now by few species and specimens (nine species, gathered in only one genus, Bathypalaemonella Balss, 1914) have been collected during different cruises, that occured, on the one hand, in the east Atlantic (Ibero-Moroccan Gulf: BALGIM-84, 1984, and SEAMOUNT 1, 1988; Açores, BIACORES, 1971), and on the other hand, mainly in the Pacific Ocean: Philippines (MUSORSTOM 2 , 1980); Indonesia (KARUBAR, 1991); New Caledonia (BIOCAL, 1985; MUSORSTOM 4, 1985; SMIB 2, 1986; VOLSMAR, 1989; HALIPRO 2, 1996); Vanuatu (MUSORSTOM 8, 1994); Marquesas islands, French Polynesia (MUSORSTOM 9, 1997), and another specimen from the Gulf of Aden (SCIMEROUAD, 1977), that prove to belong to a new species, Bathypalaemonella adenensis n. sp., which can be separated from the seven other species maintained in the genus Bathypalaemonella, by the feature of the scaphocerite (the latero-distal spine overreaches significantly the distal margin of the blade), and of the telson, ended by three pairs of spines. Seven species have been collected: apart from Bathypalaemonella adenensis n. sp., these are: Bathypalaemonella serratipalma Pequegnat, 1970; B. hayashii Komai, 1995; B. cf. humilis Bruce, 1966; B. pandaloides (Rathbun, 1906); B. brevirostris Bruce, 1986; B. pilosipes Bruce, 1986. Bathypalaemonetes n. gen. is established for the last two species mentionned above, Bathypalaemonella brevirostris and B. pilosipes, which can be separated from the species of the genus Bathypalaemonella by a set of features such as: cephalothorax with at the most one postrostral spine; major second pereopod with the ischium shorter than the merus, and its fingers showing a serie of tubercles; minor second pereopod with the dactyl far less shorter than the palm. A key to the genera and species of the family is proposed.

The other species are: Stylodactylus libratus Chace, 1983, Stylodactylus licinus Chace, 1983, and Stylodactylus tokarensis Zarenkov, 1968. On another hand, the status of a seventh species, related to Stylodactylus pubescens Burukovsky 1990, is left unresolved. The rare deep-sea shrimp family Bathypalaemonellidae is added to the Taiwanese decapod fauna, being represented by four species, one of which is new: Bathypalaemonella hayashii Komai, 1995; Bathypalaemonetes brevirostris (Bruce, 1986); Bathypalaemonetes pilosipes (Bruce, 1986) and Bathypalaemonetes chani, new species.

Cleva R. & Crosnier A. 2006. Heterocarpus tenuidentatus, a new species of shrimp from the Solomon Islands (Crustacea, Decapoda, Caridea, Pandalidae). Zootaxa 1200: 61-68
Résumé [+] [-]Heterocarpus tenuidentatus n. sp. is described from an ovigerous female collected off the Solomon Islands at a depth of between 814 and 980 meters. It is distinguished by a branchiostegal carina that extends along two thirds of the carapace, this being the only long, sharp carina on the lateral part of the carapace. It is also characterized by having the rostrum scarcely longer than half the length of the carapace, the small size of the upper rostral and postrostral teeth, the proportionally wide blade of the scaphocerite, and by being larger in size than any other Heterocarpus species.

Résumé [+] [-]More than a century after its description from the Kermadec Islands, north of New Zealand, Stylodactylus discissipes Bate, 1888 has been rediscovered south of New Caledonia, and in the Austral Islands, French Polynesia. DNA analyses show that specimens from these two widely separated areas clearly belong to the same species, and represent two populations that appear to be in early stages of speciation through isolation. Stylodactylus discissipes shares numerous morphological characters with S. serratus A. Milne-Edwards, 188 1, known from the eastern and western Atlantic, so that the synonymy of the two species could be considered. Molecular data support the small morphological differences observed, giving evidence that these two species are indeed different.

Résumé [+] [-]Five species of the family Stylodactylidae Bate, 1888 and two species of Bathypalaemonellidae de Saint Laurent, 1985, were collected by the PANGLAO 2004 and 2005 expeditions to the Philippines. A member of the Stylodactylidae, Stylodactylus gracilis new species, collected at 2149-2217 m, is described and illustrated. The new species is distinguished from the 15 described species of Stylodactylus by a very thin and glabrous integument; a very long ( 0.8 times of carapace length) antennular peduncle, by the lengthening of the second segment ( 1.8 times longer than first); thin and very long third to fifth pereopods, as a result of the lengthening of the meri and propodi. The two species of Bathypalaemonellidae, Bathypalaemonella aff. hayashii Komai, 1995, and Bathypalaemonetes brevirostris ( Bruce, 1986), represent new records for the Philippines.

Résumé [+] [-]A new genus of majoid spider crab, Pohleus gen. nov. is established for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836, based on morphology and molecular data from the partial sequences of the 12S and 16S mitochondrial genes and the 18S small subunit rRNA nuclear locus. The species are re-described and illustrated, based on material from several localities of the western Atlantic and eastern Pacific oceans. The carapace, antennal and pterygostomial spines, male thoracic sternum and first gonopods are distinctive characters, distinguishing Pohleus gen. nov. from species assigned to Macrocoeloma Miers, 1879, where P. septemspinosus and P. heptacanthus are currently included.

Résumé [+] [-]A new species ascribed to a new genus of Eusiridae, Dorotea papuana gen. nov., sp. nov. is described from bathyal bottoms of the Solomon Sea (Papua New Guinea). Closely related to the genus Cleonardo, this new genus can be distinguished from most other known eusirid genera by the presence of a telson distally cleft and distinctly bilobate, of a distal spiniform process on uropod 1 peduncle and of a simple, stout and medium length dactylus on pereopods 5–7. The combination of all these characters can be considered relevant for the affiliation of this species to a new genus within Eusiridae. Due to its very close morphological affinity to Dorotea gen. nov., the bathyal sub-Antarctic species Eusiroides aberrantis Bellan-Santini & Ledoyer, 1987 cannot be maintained in the family Pontogeneiidae and it should be transferred to the family Eusiridae.

Résumé [+] [-]A new genus and species of bodotriid cumacean, Scyllarocuma mclaughlinae n. gen., n. sp., are described from deep waters south of New Caledonia. Along with three other known genera, this new genus belongs to a group of operculate cumaceans. In all these genera an operculum closes the cavity between the infero-lateral folds of the carapace. Scyllarocuma n. gen. differs from other genera of this group in that the operculum is formed exclusively by the basis and ischium of the first pereopod, the exopod of the second pereopod is rudimentary, and the uropod endopod is one-articulated. Swimming and feeding behaviours are hypothesized based on morphological characteristics.

Résumé [+] [-]Four new species of Cumacea are described from deep-sea samples collected around Salomon Islands during the French campaign SALOMON I. Bathylamprops pagesi sp. nov. and Bathylamprops caperatus sp. nov. belonging to the family Lampropidae differ from the all currently known species by the oblique lateral carina running from anterolateral angle backwards. The nannastacid Campylaspis alisae sp. nov. can be identified by the shape of the carapace carinae, especially in dorsal view. The diastylid Oxyurostylis? salomonensis sp. nov. due to the lost of the telson tip, is difficult to assign either to the genus Diastylis Say, 1818 or to the genus Oxyurostylis Calman, 1912. At the moment, it is included provisionally to the genus Oxyurostylis and it differs from the other species in the genus by its flattened eyelobe and the higher number of setae on telson.

Résumé [+] [-]During the CORINDON II and IV expeditions, the former in the Makassar Strait and the latter in Piru Bay and Ambon Bay, Molluccas, 47 species of penaeoid shrimps were collected. They include 2 species belonging to the Benthesicymidae, 5 to the Aristeidae, 19 to the Solenoceridae, 2 to the Sicyoniidae and 19 to the Penaeidae. The twenty eight species of the first four families are considered in this study; the Penaeidae will be presented in a separate publication. Most of the species treated in this work occur in deep water, with only a few samples taken in shallow water. Two species Cryptopenaeus clevai and Solenocera moosai are new ; eight others have not been recorded previously in the waters of Indonesia. Several specimens of Solenrocera annectens (Wood Mason, 1891) have been collected; this species has not been reported since its description and additional figures, particularly of genitalia, are included in this paper. One species of the genus Pseudarktew and one of the genus Solenocem both probably new, are recorded but not named as only a single specimen of each was collected. In addition to the description of Soleizoeera moosai, the original drawings of two closely related, but little known species, S. fuxoni De Man, 1907 and S. spiiiajugo Hall, 1961, are published. The bibliography is restricted to literature on Indonesian material. For each species, one or two references, each with comprehensive bibliographies, are provided. For station lists and expedition details, see Moosa.

Résumé [+] [-]Samples collected around Madagascar and La Réunion, which included seven species of the genus Heierocarpus, led to the re-examination of all the Heterocarpus (nine species) reported previously from the region. A new species, H. calmani, which had been confounded until now with H. woodmasoni Alcock, 1901, is described. The occurrence of H. lepidus de Man, 1917, of which the specimens collected in the region had been identified wrongly as H. fricarinatus Alcock and Anderson, 1894, is proved. The re-examination of the type of H. unicarinaius Borradaile, 1915, only known specimen of this species, permits the completion of its description, but makes one wonder if this species really belongs to the genus Heterocarpus. Comparisons between specimens from Madagascar and La Réunion and specimens from the West-Pacific and from the Atlantic permit the consideration of variations associated with geographical areas and depths of sampling for H. dorsalis Bate, 1888, H. ensifer A. Milne Edwards, 1881, H. laevigaius Bate, 1888, H. lepidus de Man, 1917, and H. sibogae de Man, 1917. These comparisons also allow better definition of the features separating H. lepidus from H. gibbosus Bate, 1888, and H. iricarinatus. A careful examination of the (( ensifer )) complex permits the description of two new species, H. aniacula and H. huyasliii, and the elevation to specific rank of H. parvispina, considered, until now, to be a subspecies of H. ensifer. On the other hand, H. tricarinaius is split into two subspecies, H. tricarinaius iricarinaius, found in the Indian Ocean, and H. [ricarinatus angustus subsp. Nov., found in the West-Pacific. A key is offered for their dentification of the 25 recognized species and subspecies of the genus. Moreover, attention is drawn to the interest often presented by the coloration in the species of this genus.

Résumé [+] [-]Twenty-seven species of penaeid shrimp, belonging to the Benthesicymidae, Aristeidae and Solenoceridae families, were collected during the MUSORSTOM 1, 2 and 3 expeditions in the Philippines. None of them are new but several had not been previously reported from the Philippines and the known geographical range of some has been considerably extended. This is the case, particularly, with Parahepomadus vaubani Crosnier, 1978, known in Madagascar and Haliporus taprobanensis Alcock and Anderson, 1899, known in Madagascar and Southern India. An observation of distinct variations in Hymenopenaeus equalis (Bate, 1888) caused us to reassess specimens previously identified as this species by various authors, to correct some of these identifications and to determine more clearly the range of this species. This revision has led us to reexamine the synthypes of H. obliquirostris (Bate, 1881), only the female of which is known, and to publish drawings of specimens collected around the Hawaii islands, wrongly identified as H. equalis by Rathbun in 1906, and which must belong to an undescribed species very colsely related to H. obliquirostris. This, and the examination of the other Hymenopenaeus species in our samples, led us to attempt a better definition of the differences distinguishing H. obliquirostris, the species from Hawaii, H. neptunus (Bate, 1881), H. halli Bruce, 1966, and H. furici Crosnier, 1978. An examination of specimens belonging to Solenocera novaezelandiaa, Borradaile, 1916, supports the synonymy of this species with S. comata Stebbing, 1915, the slight differences observed being perhaps at most distinctive of forms. On the other hand we do not consider S. alticarinata Kubo, 1949, to be synonymous with S. choprai Nataraj, 1945, as several previous authors have done. Lastly, we distinghished two forms, alfonso and inermis, of Solenocera alfonso Pérez Farfante, 1981.

Résumé [+] [-]This paper is a continuation of the work published in 1987, in which a group of 10 species and one subspecies of Indo-West Pacific Metapenaeopsis without stridulating organs were treated. The study presented here is based on abundant material supplied by a large number of ORSTOM collections made in the Indo-West Pacific (Madagascar, Seychelles and New Caledonia) and by joint expéditions by ORSTOM and the Muséum national d'Histoire naturelle (MUSORSTOM 1-6, CORINDON, BIOCAL, BIOGEOCAL, CHALCAL 1 and 2 cruises) in the Philippines, Indonesia, New Caledonia and Chesterfield Islands and by the MD 32 cruise in the vicinity of La Réunion, supported by the TAAF (Terres Australes et Antarctiques Françaises). Additional material from the collections of the National Muséum of Natural History, Washington, from several Australian Muséums, as well as from the Muséums of Amsterdam, Leiden, Copenhagen and Frankfürt was also examined. Problems have occurred because of insufficient original descriptions and these have resulted in many errors in the Iiterature. All the type specimens have been re-examined (except for M. gallensis Pearson which is apparently lost), and also most of the specimens cited in the Iiterature. Corrected identifications and distributions are given. Among the species previously described, 18 are recognized as valid, either as species or as subspecies : M. assimilis (de Man, 1920), M. ceylonica Starobogatov, 1972, M. commensalis Borradaile, 1898, M. dalei (Rathbun, 1902), M. distincta (de Man, 1907), M. evermanni (Rathbun, 1906), M. faouzii (Ramadan, 1938), M. gallensis (Pearson, 1905), M. hilarula (de Man, 1911), M. Iamellata (de Haan, 1844), M. mannarensis de Bruin, 1965, M. mogiensis consobrina (Nobili, 1904), M. mogiensis mogiensis (Rathbun, 1902), M. quinquedenta (de Man, 1907), M. tarawensis Racek & Dali, 1965, M. vaillanti (Nobili, 1904), M. velutina (Dana, 1852), M. wellsi Racek, 1967. Six species are considered to be synonyms : M. borradailei (de Man, 1911) = M. commensalis Borradaile, 1898. M. bruini Starobogatov, 1972 = M. mogiensis consobrina (Nobili, 1904). M. caliper Liu & Zhong et al., 1988 = M. velutina (Dana, 1852). M. insona Racek & Dali, 1965 = M. velutina (Dana, 1852). M. perlarum (Nobili, 1905) = M. mogiensis consobrina (Nobili, 1904). M. raceki Starobogatov, 1972 = M. assimilis (de Man, 1920). Fifteen species and 2 subspecies are described as new : M. costata, M. difficilis, M. gaillardi, M. incisa, M. laubieri, M. marquesas, M. menoui, M. mogiensis complanata, M. mogiensis intermedia, M. parahilarula, M. persica, M. propinqua, M. proxima, M. quadrilobata, M. richeri, M. spatulata, M. spiridonovi. A total of 35 species and subspecies (not counting one form described under the name M. aff. Distincta which is probably new) are treated. Thus 46 species and subspecies of Metapenaeopsis lacking stridulating organs are now known to occur in the Indo-West Pacific. Two identification keys are presented : one for males, another for females. They are mainly intended as a guide to the numerous figures included in the paper. Illustrations of the genitalia provide assistance in recognizing the characters used to separate the species. All the petasmata are depicted with lobes both closed and separated. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies high species diversity of the Philippines-Indonesia fauna is evident. Déductions about the biogeography must be regarded with caution because they may reflect differences in sampling effort across the various areas and also because many small species have not been adequately collected. It is of particular interest to note that in the New Caledonian region, where there have been many collections made using a variety of methods, 17 species are known, whereas from the vast Philippines-Indonesia region only 19 have been recorded and only 9 from the whole of Australia. Finally some general considerations on the genus Metapenaeopsis are presented and it is suggested that the species currently assigned to it should perhaps be placed in 2 or 3 genera. An effort has been made to define the groups that might be deserving more formal recognition.

Résumé [+] [-]A new species, Heterocarpus intermedius, confused until now with H. woodmasoni Alcock, 1901, is described after specimens caught off the east coast of Australia, New Caledonia, the Loyalty and the Chesterfield islands, and the Combe and Tuscarora banks. It can be separated mainly by the fact that it has no postrostral crest and only two pairs of dorsolateral spines on the telson. An addition to the indentification key of the Heterocarpus species publishede by Crosnier (1988) is proposed.

Crosnier A. 2000. A new genus and species of hippolytid shrimp (Decapoda, Caridea) from Wallis Island, south-west Pacific. Journal of Crustacean Biology 20(Special number 2): 109–115
Résumé [+] [-]A new genus and species, Eumanningia pliarthron, is described based on a specimen collected during the MUSORSTOM 7 cruise on the outer slope of Wallis Island, South-West Pacific, in depths of 890-915 m. Using available identification keys, this specimen would be placed in the genus Merhippolyte Bate, but as it differs from all species of this genus in several characters, of which the most obvious are: presence of three strong movable postrostral spines, posterior part of the third abdominal somite produced in an extremely large sharp tooth, left second pereiopod very long and with merus and carpus subdived into an unusually high number of articles, a new genus is created.

Résumé [+] [-]The material examined for this note was obtained mostly by the MUSORSTOM 9 Expedition to the Marquesas, French Polynesia, in 1997. Collections were made from the intertidal zone to 260 m deep. Twenty-four species, of which four are new, are listed. The new species are: Portunus paralatibrachium n. sp. Which is very close to P. latibrachium (Rathbun, 1906) but which can be easily distinguished by the shapes of the abdomen and male first pleopod; Thalamita difficilis n. sp. Which belongs to the admete group and the auauensis-margaritimana subgroup, but can be distinguished from these two species by a series of characters (particularly the shape and positon of the frontal lobes and the male pleopods); Thalamita pseudopelsarti n. sp. Which is very close to T. pelsarti Montgomery, 1931, from which it is distinguished by a few but constant characters (shape and position of the frontal lobes, reduction in the size of the penultimate anterolateral tooth of the carapace, spinulation of the basal antennal article, etc.); Thalamita simillima n. sp. Which is very similar to T. pseudospinifera Crosnier, 1975 and from which it can be distinguished by an undivided first anterolateral tooth of the carapace, the spinulation and granulation of the chelipeds and the basal antennal article. A new subspecies, Thalamita auauensis dytica n. ssp., is erected for the specimens from the Indian Ocean previously identified as Thalamita auauensis Rathbun, 1906; they are distinguished by the ornamentation of the chelipeds and the form of the sixth abdominal segment. Two species known until now by their holotypes only have been rediscovered: Charybdis rathbuni Leene, 1938, described from Indonesia, and Thalamita multispinosa Stephenson & Rees, 1967, described from Hawaii. Thalamita seurati Nobili, 1906, known only by its holotype, unfortunately a female, is redescribed and illustrated. The possibility that T. wakensis Edmondson, 1925 is a synonym of the latter species is also discussed.

Résumé [+] [-]Based on rather abundant material from the Indo-West Pacific, the number of species in the genus Parathranites Miers, 1886 is elevated from two to eight. The six new species are P. granosus n. sp., P. tuberosus n. sp., P. tuberogranosus n. sp., P. ponens n. sp., P. intermedius n. sp. and P. parahexagonum n. sp. Examination of the type series of the type species for the genus, P. orientalis Miers, 1886, shows that it contains two species; a lectotype is designated for P. orientalis. The main morphological characters used for differentiating the species are the breadth/length ratio of the carapace (correlated with the length of the fifth anterolateral teeth of the carapace) which can vary from 1.3 to 2.1, the presence or absence of a median tubercle on the posterior part of the cardiac area, the granulation of the carapace and the shape of the first male pleopods. An identification key for members of this genus is proposed.

Résumé [+] [-]Hymenopenaeus obliquirostris ( Bate, 1881), a relatively poorly known species, is redescribed, figured and compared with H. halli Bruce, 1966. Two other species of Hymenopenaeus, H. methalli from the southwest Pacific and H. fallax from Hawaii, are described as new. All these species are closely related to one another. They are distinguished essentially by the presence or absence of a postrostral carina, the presence or absence of a fixed spine on the merus of the first pereopods, and the shape of parts of the thelycum and petasma.

Résumé [+] [-]During the French cruises conducted in the South-West Pacific during the last 20 years, two new Parapenaeus were found: Parapenaeus kensleyi n. sp., off New Caledonia, Vanuatu and the Fiji Islands; and Parapenaeus cayrei n. sp., off Tonga and the Chesterfield Islands. Amongst the Parapenaeus species provided with a branchiostegal spine on the anterior border of the carapace and extended by a rather long carina, P. kensleyi n. sp., with its long and sinuous rostrum, is related to P. australis Dall, 1957, P. lanceolatus (Bate, 1881) and P. perezfarfante Crosnier, 1986. Parapenaeus cayrei n. sp., with its short and straight rostrum, is related to P. fissurus (Bate, 1881), P. sextuberculatus Kubo, 1949 and P. ruberoculatus Hall, 1962. In both cases, the shape of the distal part of the ventrolateral lobe of the petasma in the males, the arrangement of the lateral bulbous portions and median tubercles, and the bulgings of the thelycum in the females allow the new species to be readily distinguished.

Résumé [+] [-]Penaeopsis (Crustacea, Decapoda, Penaeidae) collected in the south-west Pacific by French expeditions since 1976. Description of a new species. This work is based on collections made in the south-west Pacific by IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris. It deals with four species of Penaeopsis Bate, 188 1: P challengeri de Man, 1911, P eduardoi Perez Farfante, 1977, P rectacuta (Bate, 188 1), and a new species, P mclaughlinae n. sp. Depth zones and geographic distributions of the three known species are revised, especially those of P challengeri. Penaeopsis mclaughlinae n. sp. is closely related to P eduardoi but it is easily distinguished by the more sinuous shape of the distal part of the ventrolateral lobules of the petasma, and the large rounded protuberance on the median plate of the thelycum.

Résumé [+] [-]The species of the genus Trachypenaeopsis (Crustacea, Decapoda, Penaeidae). Morphological and molecular approaches. The genus Trachypenaeopsis Burkenroad, 1934 has been known in the Indo-West Pacific region by two species, T richtersii (Miers, 1884), described from Mauritius and recorded afterwards as far as Indonesia, Japan, and Hawaii, and T minicoyensis Thomas, 1972, known only from the Laccadive Is. The present work shows that T minicoyensis is a synonym of T richtersii, that identifications of material from China, Taiwan, and Hawaii are erroneous and that these specimens are not morphologically distinguishable from the Atlantic species, T mobilispinis (Rathbun, 1915), described from the West Indies. DNA analyses show that Pacific specimens other than T. richtersii belong to one species: genetic divergence is not higher than 2.2%, while the genetic distance between Pacific and Atlantic populations averages 3.6%. The absence of morphological differences between these two sets of populations indicates that the populations are becoming genetically different but cannot yet be considered separate species. The colour patterns of the Atlantic and Pacific specimens have not been determined so it is possible that these Populations could eventually be shown to represent separate sibling species.

Résumé [+] [-]This work deals with 31 species of Sicyonia H. Milne Edwards, 1830, based on the collections made by the IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris, and on the collections of 28 other museums. Nineteen species are considered valid: S. australiensis Hanamura Wadley, 1998; S. benthophila de Man, 1907; S. bispinosa de Haan, 1850; S. curvirostris Balss, 1913; S. fallax de Man, 1907; S. furcata Miers, 1878; S. inflexa (Kubo, 1949); S. japonica Balss, 1914; S. laevis Bate, 1881; S. lancifer (Olivier, 1811); S. longicauda Rathbun, 1906; S. nasica Burukovsky, 1990; S. ocellata Stimpson, 1860; S. parafallax Crosnier, 1995; S. parvula de Haan, 1850; S. rectirostris de Man, 1907; S. trispinosa de Man, 1907; S. truncata (Kubo, 1949) and S. vitulans (Kubo, 1949). Four species are considered to be synonyms: S. cristata (de Haan, 1844) = S. lancifer; S. formosa (Chan & Yu, 1985) = S. furcata; S. ommanneyi Hall, 1961 = S. ocellata; S. nebulosa Kubo, 1949 = S. laevis. Twelve species are described as new: S. abathophila n. sp., S. adunca n. sp., S. altirostrum n. sp., S. dejouanneti n. sp., S. komai n. sp., S. longicornis n. sp., S. metavitulans n. sp., S. parajaponica n. sp., S. robusta n. sp., S. rocroi n. sp., S. rotunda n. sp. and S. taiwanesis n. sp. Some forms, near S. australiensis and S. dejouanneti n. sp., are mentioned but not named because the material available is insufficient. An attempt is made to classify the Indo-West Pacific species of Sicyonia into eight groups. Some groups are coherent, while others are certainly artificial. Some species cannot be placed in any of the groups and the placement of several species known from one sex only remains hazardous. An identification key is presented. Particular care was taken in illustrating the genitalia, which provide the most important characters for recognizing the species. Colour photographs show the coloration of living specimens of 17 species. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies, high species diversity of the Philippines-Indonesia fauna is evident, as well as the reduction of the number of species when one moves away from the area, except for New Caledonian area because of the unusually high h density of the samples collected in this area.

Résumé [+] [-]After a discussion of the valid publication date of the genus Intesius Guinot Richer de Forges, 1981 and of the structure of the male abdomen in this genus, new samples of L pilosus Guinot & Richer de Forges, 1981 are recorded from the Philippines and a new species, Intesius richeri n. sp., is described, based on a specimen from New Caledonian waters. The latter can be distinguished from the two other species of the genus by its more rectangular carapace, a less developed pilosity (particularly on the walking legs), and the second male pleopods ending in a very slender tubular part. Two other specimens, from Guam, are described under the name I lucius n. sp. They are very close to I. crosnieri Davie, 1998, known by a single specimen, but differ mainly by slightly longer, more slender and less pilose walking legs.

Résumé [+] [-]The genus Platepistoma Rathbun, 1906, is reviewed and considered ta be valid and not a subgenus of Cancer Linnaeus, 1758. Three new species are described viz. P. nanum, P. kiribatiense and P. seychellense. They are mainly separated on the distinctness of the carapace regions, extent of dorsal granulation of the carapace, and shape of the telson of the male abdomen. The genus is considered to contain seven species, and a key is provided. The name Platepistorna anaglyptum Balss, 1922, is resurrected and the synonymy clarified. Cancer balssii Zarenkov, 1990, is placed in Platepistoma. Cancer (Glebocarcinus) Nations, 1975, is also considered a valid taxon and provisionally allowed to remain as a subgenus of Cancer; it contains at least Cancer oregonensis Rathbun, 1898, and C. amphioetus Rathbun, 1898. Platepistoma is restricted to deeper water, mostly greater than 350 m, in the Indo-West Pacific Oceans, and this is briefly discussed in relation to recent biogeographic theories.

Mémoires du Muséum national d'Histoire naturelle 193:393-410, ISBN:2-85653-585-2
Résumé [+] [-]Echinolatus n. gen. is described for four species, E. bullatum (Balss, 1923), from the Juan Fernandez Islands off Chile, E. caledonicum (Moosa, 1996) from New Caledonia, E. proximum n. sp. from French Polynesia, and E. poorei n. sp. from the Great Australian Bight and southern Victoria. The first two species had been previously attributed to Nectocarcinus A. Milne Edwards, 1860. Echinolatus is characterised by a subhexagonal carapace, a quadrilobate front, at least the last pair of anterolateral carapace teeth, and usually others, bearing spinules or spiniform denticles on the anterior margins, the chelipeds having the carpus armed with a long pointed tooth at its anterointernal angle which also has a smaller strong tooth basally. E. bullatum is redescribed.

Résumé [+] [-]The taxonomy of majid spider crabs collected from recent southwest Indian Ocean cruises belonging to Eurynome Leach, 1814, and allied genera is treated. Eurynome longimana Stimpson, 1857, long synonymised with the European E. aspera (Pennant, 1777), is here recognised as a distinct species. Stimpson’s (1857) species can be distinguished by the armature of granules on the third maxilliped, proportions and armature of the ambulatory merus, relatively shorter ambulatory dactylus, structure of the male sternopleonal cavity and relative proportions of the male first gonopod. The composition of Choniognathus Rathbun, 1932, is discussed and the type species, C. koreensis Rathbun, 1932, is figured. One species, C. verhoeffi (Balss, 1929), is not considered to be a member of Choniognathus and its taxonomy is discussed. A new spinose species, C. spinosus, is also described. Seiitaoides Griffin & Tranter, 1986, is revised, and two new species, S. mirabilis and S. kabuto, are described and compared with S. orientalis (Sakai, 1961) and S. stimpsoni (Miers, 1884). The poorly known Eurynome elegans Stebbing, 1921 is rediscovered, its taxonomy clarified and the species is shown to belong to Kasagia Richer de Forges & Ng, 2007. A second species of Kasagia, K. sudhakari Padate, Manjebrayakath & Ng, 2019, recently described from the Arabian Sea is recorded from southwest Indian Ocean.

Résumé [+] [-]Over the last decade or so, much has been written on the classification of Decapoda, fuelled by a surge in molecular phylogenetic studies, as well as close scrutiny of internal and external morphological characteristics. As discussed by Fransen & De Grave (2009), such studies on shrimps are still somewhat ”thin on the ground”, at least compared to the more extensive work done on the Brachyura and Anomura. At a higher level in decapod classification it has long been recognised that three distinct lineages of shrimps can be distinguished: Dendrobranchiata, Stenopodidea and Caridea, a system which has not been seriously challenged by recent studies. The internal classification of Dendrobranchiata and Stenopodidea alike has been stable for some time, with the only major addition being the family Macromaxillocarididae Alvarez, Iliffe & Villalobos (2006) to the Stenopodidea in recent years. A different picture has emerged for Caridea very recently with Bracken et al. (2009) and Chan et al. (2010), both drawing attention to the non-monophyletic status of certain superfamilies and families. Further, we are aware of work currently in progress (some by the authors of this compilation) corroborating the hypothesis that the current classification of Caridea is unnatural, lines of study which will lead to the resurrection of certain family names as well as further refinement to other families. As one of our objectives for the current effort was to link this compilation of species level information with the earlier work by Chace (1992) for families and Holthuis (1993a) for genera, we have elected to largely follow the classification outlined by De Grave et al. (2009) which builds upon this earlier work. As such, it was deemed advisable to include the recently resurrected family Acanthephyridae Spence Bate, 1888 in the superfamily Oplophoroidea, rather than in this catalogue to create a new superfamily, which would perhaps be more congruent with the results in Chan et al. (2010). Although we follow herein the classification scheme of De Grave et al. (2009), two recent changes have been implemented. The clarification of the status of Galatheacaris abyssalis Vereshchaka, 1997a, as the megalopal stage of Eugonatonotus chacei Chan & Yu, 1991a, by De Grave et al. (2010) resulted in the removal of the family Galatheacarididae and superfamily Galatheacaridoidea in the current listing. Bracken et al. (2010) clarified the status of the family Procarididae, resulting in the recognition of a fourth group of shrimp, Infraorder Procarididea.

Résumé [+] [-]The small family Retroplumidae, one of the smallest among Barchyura, includes only two genera in the Recent fauna : Retropluma Gill, 1874, with 6 species, two of which are new ; and Bathypluma, gen. nov., with three species, two of which are also new. The first part of this work deals with systematics of the family. It is based mainly upon the material collected in the Philippines in the course of the first three MUSORSTOM expeditions. In addition to the description of the new taxa, Retropluma serenei, R. quadrata, Bathypluma spinifer and B. forficula, the previoulsy known ones are revised. This is supplemented by a few comments on the geographical and bathymetrical distribution of the various species, and by a few remarks concerning their ecology. In the second part, a critical review of fossil remains attributed to the family reveals that only Eurafricans or Asiatic fossils belong with certainty to the retroplumid lineage and that the species of American origin so far described should be excluded from the group. A detailed story of both living and extint species of retroplumids shows the great originality of this little group, which is unique in particular so far as the morphology of the orbito-antennary region and of the posterior thoracic region go. They appear in the fossil records from the origin of the upper Cretaceous, and it may be surmised that they represent an early offshoot of the main eubrachyuran, or true crab, line. The rank of superfamily herein assigned to the family Retroplumidae indicates the impossibility of linking this small group to any other family of Brachyura.

Résumé [+] [-]The genus Eumunida, belonging to the family Chirostylidae, is represented in New Caledonia and Chesterfield Islands by seven species, ail of them new to Science : Eumunida keijii, E. sternomaculata, E. annulosa, E. capillata, E. parva, E. minor and E. marginata. Four species (E. sternomaculata, E. annulosa, E. capillata, and E. parva) are very common at depths between 400 and 600 meters, being currently caught at the same stations. The other species are scarce, and hâve been collected either at the same depths (E. keijii), or in shallower waters (E. minor and E. marginata). The high abundance of thèse species could be related to the présence on the bottom of hydrocorallians of the family Stylasteridae. Three species (E. keijii, E. annulosa and E. sternomaculata) belong to the group A after GORDON (1930), characterized by a spine on either side of the sternal segment bearing the chelipeds. The latter two of thèse species hâve a pad on the ventral surface of the palm. E. keijii is closely related to E. pacifica Gordon, 1930, from the south of Timor, but, among other différences, the two are readily distinguished by the size of the first hepatic spine, the médian sinus of the third thoracic sternite and the scales on the sternal segments. E. sternomaculata resembles E. sp., from southeast Australia (E. picta, GORDON, 1930, in part) ; both are nevertheless easily distinguished by the shape of the frontal part of the carapace, the direction of the supraorbital spines and the relative lengths of the anterolateral spines and antennal peduncles. E. annulosa is close to E. sternomaculata. Thèse two species are differentiated by the shape of the rostral spines, the ornamentation of the carapace, the length and shape of the chelipeds and the présence or absence of a disto-mesial spine on the carpus of the chelipeds. E. marginata, E. capillata, E. parva and E. minor belong to the group B, after GORDON, that has no spine on either side of the sternal segment bearing the chelipeds. With the exception of E. parva, ail the other species are provided with a pad on the ventral surface of the palm. E. parva is closely related to E. smithii Henderson, 1883, from the south of Timor, and to E. propior Baba, 1988, from the Philippines. A discussion about the identity of the material of E. smithii from différent expéditions and the relationships between the three species is provided. The maies of thèse three species are characterized by the présence of pleopods on the second to fifth abdominal segments. E. capillata is very close to E. parva, but can be easily distinguished from it by a number of characters. The main différence is the présence of a pad on the ventral surface of the cheliped palm in capillata, and its absence in parva. E. minor is the smallest représentative of the genus. The species is clearly distinguishable from ail the others of the group B by the présence of two prominent spines on the merus of the third maxillipeds, and of four longitudinal rows of spines on the merus of the cheliped. Its closest relative is E. balssi Gordon, 1930. E. marginata is related to E. gordonae Baba, 1973, from Japan. However, the length and the spinulation of the pereopods are very different.

Résumé [+] [-]New specimens of the genus Eumunida Smith have been collected in the Indo-West Pacific, including new or poorly known species. The study of the material collected, together with the reexamination of types or published specimens of previously described species, demonstrated the need for a revision of the genus in the vast Indo-West Pacific area. The two groups of species recognised by authors since the work of GORDON (1930) are elevated in the present paper to subgeneric rank. The nominal subgenus Eumunida includes those species bearing a pair of well-developed spines on the anterior margin of the thoracic sternite 4 (group A of GORDON). The new subgenus Eumunidopsis, with Eumunida capillata de Saint Laurent & Macpherson, 1990, as type species, includes the species in which the anterior margin of this sternite is at most finely denticulated, most usually without any prominent spines. Four new species are established in the subgenus Eumunida: E. (Eumunida) treguieri sp. Nov., from French Polynesia, E. (Eumunida) multilineata sp. Nov., from the eastern coast of Australia, and E. (Eumunida) depressa and E. (Eumunida) macphersoni spp. Nov., both from Japan. Two new Indonesian species are described in the subgenus Eumunidopsis, E. (Eumunidopsis) ampliata and E. (Eumunidopsis) karubar spp. Nov. Apart from the description of new taxa, the present study includes a revised list of all known species from the Indo- West Pacific area, with an identification key, in French and English, along with references, types, remarks on the affinities and distribution. Whenever it has seemed useful, new diagnoses and illustrations of poorly known species are provided for each taxon. Two species have been collected in French Polynesia, where the genus had never before been found. E. (Eumunida) treguieri sp. Nov. Is a large species, close to E. (Eumunida) similior Baba, 1990, from Madagascar and to another new species from Japan. The second Polynesian species is E. (Eumunida) keijii de Saint Laurent & Macpherson, 1990, previously known only from New Caledonian waters. The Franco-Indonesian cruise KARUBAR, in 1992, has provided a few Eumunida. This material includes three specimens of E. (Eumunidopsis) smithii Henderson, 1885, about 20 individuals of a closely-allied species, E. (Eumunidopsis) karubar sp. Nov., a very small specimen of E. (Eumunidopsis) laevimana Gordon, 1930, never found since its original description, and one young male, provisionally identified as E. (Eumunida) pacifica Gordon, 1930. The taxonomic problems centered around Eumunida smithii, already discussed in DE SAINT LAURENT & MACPHERSON (1990a), have been solved ; the new KARUBAR material identified with it allows a better definition of the species and leads to the proposal of the synonymy of Eumunida propior Baba, 1988 with HENDERSON'S species. The "Siboga" specimens identified as E. balssi by VAN DAM (1933) are conspecific with it, while the material identified by GORDON (1930) and VAN DAM (1933) as E. smithii Henderson represents the same new taxon, herein described as E. (Eumunidopsis) ampliata sp. Nov. The small male from the "Albatross" dredgings cited in BABA (1988) belongs to another species very close to, if not identical with, E. (Eumunidopsis) capillata de Saint Laurent & Macpherson, 1990. The KARUBAR collections also include two dozen individuals of another new species, E. (Eumunidopsis) karubar sp. Nov., very close to E. (Eumunidopsis) parva de Saint Laurent & Macpherson, 1990, and E. (Eumunidopsis) smithii. These three species form a small unit of related taxa, without a pad on the propodus of the chelipeds, and in which the males have vestigial pleopods on abdominal segments 3 to 5, absent in all other Eumunida. Examination of three Japanese specimens of Eumunida cited by MIYAKE (1982: 144, pi. 48), and BABA (1986: 287, fig. 116) under the names E. fumambulus and E. pacifica, respectively proved to belong to neither species: they represent two different, new species, which are here described as E. depressa and E. macphersoni spp. Nov. The first is close to the new Polynesian species E. treguieri, the second to E. pacifica and E. keijii. The geographical ranges of several species are extended: E. (Eumunida) keijii de Saint Laurent & Macpherson, 1990, described from New Caledonian waters, has now been found in French Polynesia and off Wallis Islands in the South Eastern Pacific. Specimens attributed to E. (Eumunida) capillata, described by the same authors from New Caledonia, have been collected in Indonesia during the French Indonesian cruise KARUBAR; the "Albatross" specimen from the South of Taiwan, refered to E. smithii by BABA (1988), is also here attributed to E. capillata. Three small Eumunida (Eumunidopsis) from the Marshall Islands (Bikini), provided by the National Museum of Natural History, Washington, are identified as E. (Eumunida) minor de Saint Laurent & Macpherson, 1990, previously known only from New Caledonia and Madagascar.Some characters, used to differentiate the species, can vary according to the size and sex of the specimens. The striae of the carapace and abdominal tergites, the spinulation of the chelipeds, and the development of the ventral pad on their palm, for example, are likely to differ noticeably from the juvenile to the adult stages. Moreover, autotomy of one of the chelipeds is not infrequent in the genus, and may lead to a dimorphism in size and/or ornamentation of the regenerated appendage. Despite our efforts, the species identification of Eumunida remains difficult, the more so when only isolated specimens are available. Some of our taxonomic conclusions may need to be re-appraised if and when further material is collected. It should also be noted that the colouration of fresh specimens is important and has proved useful in helping to distinguish species in this study.

Résumé [+] [-]A new genus is porposed for a new species widely distributed in the western Pacific Ocean from the Philippine Islands in the northwestern Pacific south to Kermadec Islands of New Zeland. Jacquesia n. genus, bears considerable similarity to Iridopagurus de Saint Laurent-Dechancé, 1966, in lacking an accessory tooth on the crista dentata of the third maxilliped, but having eleven pairs of quadriserial gills, slender elongate and subequal chelipeds and a well-developed left male sexual tube. It is distinguished from Iridopagurus by he presence of paired fisrt pleopods in females. The new species is a very distinct, but morphologically variable species. Theses variations, however, do not appear to be correlated with either size or sex.

Résumé [+] [-]Based on the specimens collected during three deep-sea cruises, and deposited at the Muséum National d’Histoire Naturelle (MNHN) in Paris, we analysed the diversity of benthic communities within the EEZ of French Polynesia. The literature and the MNHN database allowed us to inventory 471 species of invertebrates, among which 169 were newly described. We mainly found data for Mollusca, Crustacea, Brachiopoda and Crinoidea. We also found samples from other taxa, which still remain unidentified within the collections of the MNHN. Although this inventory is incomplete, we demonstrate that the deep waters of French Polynesia host unique benthic communities and endemic species. Using diversity and multivariate analyses, we show that the deep-sea benthic communities are structured by depth, habitats, geography and also by the presence of polymetallic crust. Furthermore, by focusing on the molluscs of the central area of French Polynesia, we show that the spectrum of shell size differs among deep-sea habitats. Specifically, shells tend to be smaller on encrusted seamounts than on island slopes. Together with the size range of organisms, low abundance, rarity and endemism designate these habitats as sensitive. These results should thus be taken into account in the evaluation of the expected impact of mining activities on biological communities.

Résumé [+] [-]Several squat lobster specimens of the genus Munidopsis were collected from an artificially placed carcass fall (cow bones) on Weijia Guyot in the western Pacific Ocean. Based on morphological comparisons and molecular analysis, three specimens were confirmed as juveniles of M. albatrossae Pequegnat & Pequegnat, 1973, which represents the first record of this species in the western Pacific. The other specimens collected are newly described as Munidopsis spinifrons sp. nov., which is distinguished from the closely related species in having a spinose rostrum and basal lateral eyespine on the eyestalk. The M. albatrossae from Weijia Guyot exhibited very low genetic distances when compared with a conspecific sample from Monterey Bay, USA, and the closely related species M. aries (A. Milne Edwards, 1880) from the northeastern Atlantic. A phylogenetic tree based on the mtCOI gene shows M. spinifrons sp. nov. as sister to M. vrijenhoeki Jones & Macpherson, 2007 and M. nitida (A. Milne Edwards, 1880), although M. vrijenhoeki presents a complex relationship with other species in the clade. The systematic status of the new species and the closely related species are discussed.

Zoological Journal of the Linnean Society. DOI:10.1093/zoolinnean/zly018
Résumé [+] [-]Since Darwin, the presence of dwarf males in cirripedes has received much attention when trying to understand the evolution of reproductive strategies. The Scalpellidae is a large and monophyletic family of pedunculated barnacles, where the males always attach in confined areas (receptacles) on the rim of the mantle cavity. We used a broad range of microscopic techniques to describe the morphology of the dwarf male receptacle area in 11 species of scalpellids. We correlated this with their diverse habitats and reproductive biology. The purpose was to search for preformations in the receptacle that could assist male settlement and provide the female/hermaphrodite with control over the number eventually to be carried. The species fall into three groups based on their species-specific receptacle morphology and level of preformation. We concluded that small-sized, short-lived scalpellids occupying ephemeral substrata tend to invest more resources in caring for very few males. In contrast, large and long-lived species continuously acquire new males throughout their lifetime without investing any resources in their care. Thus, ecologically different habitats have directed the evolution of different mating systems. We discuss our findings in the light of a recent phylogenetical framework and the evolution of sexual systems.

Forest J. 1987. Ethology and Distribution of Pylochelidae (crustacea Decapoda Coenobitoidea). Bulletin of Marine Science 41(2): 309-321
Résumé [+] [-]The Pylochelidae differ from the other hermit crabs by the complete segmentation of the abdomen and the presence of paired appendages on each of its segments. They do not usually inhabit gastropod shells, but dwell in decayed pieces of wood, stones, tusk-shells, or living sponges. A recent revision, founded on most of the previously recorded specimens and on a large unidentified collection, increased the number of known species from 16 to 39, and the genera from 5 to 7. Two new subgenera have been established, and the family divided into six subfamilies. This paper deals first with the eco-ethological characteristics of the different taxa. According to their dwelling, genera and subgenera can be classified, as a whole, as xylicolous, petricolous, tusk-dwellers, spongicolous, with a few specifical or individual exceptions. In connection with the habitat, adaptive features have been described: opercular structures, boring "rasp," stridulating apparatus ... The Pylochelidae are present in the Indo- West Pacific (36 species or subspecies in 6 genera), and in the NW Atlantic (4 species in 3 genera). Two genera only, belonging to the sole non monotypic subfamily, provide a biogeographical link between the two areas. In I-W.P., the family is known from the SW Indian Ocean to Japan, Kermadec Islands and New Zealand. Indonesia, with 14 species and 5 genera appears as a center of dispersion and diversification. Japanese endemism is noteworthy: one genus and six of the seven species have not been reported elsewhere. The probable relation between the availability of dwelling material and the geographical distribution is also discussed. The vertical distribution extends from 30 to 1,570 m, but the group is mostly represented between 200 and 500 m, where 28 species are living.

Résumé [+] [-]The family Pylochelidae or « symetrical pagurids » (Crustacea Coenobitoidea). Pylochelid Pagurids differ mostly from all other members of the section by a well developped abdomen, in which ail segments are articulated and provided with a pair of appendages, similar in this way to many other Reptant Decapods. They are commonly called " symmetrical " Pagurids, but this is not correct, since in one genus the abdomen, telson and pleopods are noticeably asymmetrical. Our knowledge of the group was restricted to 16 species, recorded from a few rather deep water stations in Indo-West-Pacific and Western Atlantic, most of them known only from their type localities. The abundance of new material, originating mainly from Albatross dredgings and from recent French explorations in the I.W.P. has led to the present systematic revision. As a resuit, 24 new species or subspecies are added to the 16 previously established valid species ; the five known genera, Pomatocheles, Pylocheles, Mixtopagurus, Cheiroplatea, and Parapylocheles, have been redefined, some species of Cheiroplatea transfered to Pylocheles and the latter divided into three subgenera (Pylocheles, Xylocheles subgen. Nov. And Bathycheles subgen. Nov.). Besides, two genera, Cancellocheles gen. Nov. And Trizocheles gen. Nov. Are created. The Pylochelidae could be considered up to now as a restricted family of infrequent species : apart from 3 forms reported in several occasions from Japanese waters, the whole number of specimens recorded in literature did not exceed 60, captured in about 30 stations. The present revision includes more than 400 specimens, collected in ca. 200 stations ! The importance of Pylochelid fauna in tropical and subtropical waters must therefore not be neglected, and, most probably, new taxa and new localities will be added in the future. This research however has not been restricted to the description of new forms. Investigations on relationships between the various généra have shown that the whole group is made up of several distinct phyletic lines, whose respective affinities do not appear clearly, and the family had to be divided, at least provisionnaly, into 6 subfamilies. Regarding the systematic position of the Pylochelidae within the section Paguridea, they are classified in the superfamily Coenobitoidea, and a comparative study of their main characters suggests that they are close to the family Diogenidae. They cannot however be regarded as primitive représentatives of that family : both Diogenidae and Pylochelidae probably have a common ancestor, but evolved separately along various phyletic lines. In the taxonomic part of this work is also described and illustrated for the first time the glaucothoe stage of a Pylochelid, Pomatocheles stridulans sp. Nov. The richness of the new material at the origin of the systematic revision of the family has also provided a quantity of information on the ecology or the habitat of many forms, and on the interprétation of various adaptive morphological structures. According to their dwelling, généra and subgenera can be classified, as a whole, as xylicolous, petricolous, tusk-dwellers, spongicolous, with a few specific or individual exceptions. In connection with the habitat, adaptive features have been described : opercular structures, boring "rasp", stridulating apparatus... The Pylochelidae are known from two disjunct areas, the Indo West-Pacific (36 species or subspecies in 6 genera and 5 subfamilies) and the North Western Atlantic (4 species in 3 généra and 2 subfamilies). In Indo- West Pacific, their distribution is extremely wide, from South Africa to the Kermadec Islands, and from Japan (ca. 38° N) to southern New Zealand (ca. 46° S). Indonesia, with 14 species and 5 généra appears as the center of dispersion and diversification. Japanese endemism is noteworthy : one genera and 6 out of the 7 species have not been reported elsewhere. In North Western Atlantic Pylochelidae, poorly represented, extend from Bardados to the North Western part of the Gulf of Mexico and from ca. 10° N to 35° N. Two genera only, belonging to the sole non monotypic subfamily (Pylochelinae) provide a biogeographical link, probably from Tethyan origin, between the two areas. The probable relation between the availability of dwelling material and the geographical distribution is also discussed. The vertical distribution extends from 30 to 1,570 meters, but the group is mostly represented between 200 and 500 m, where 28 species have been found. 3 species only are presumably usually living above 200 m, 9 have been recorded from 500 to 750 m and no more than 5 beyond.

Résumé [+] [-]Crustacea Decapoda Anomura : Revision of the genus Trizopagurus Forest, 1952 (Diogenidae), with the establishment of two new genera. Prior to the present study, the genus Trizopagurus Forest, 1952, included ten species, mostly from the Indo-West Pacific, but two of them from the Eastern Atlantic and one from the Eastern Pacific. Following the examination of about 350 spécimens, this genus has now been revised and two new genera established, Ciliopagurus gen. Nov. And Strigopagurus gen. Nov. In addition 24 species are assigned to the three gênera, 14 of thèse being described as new. After an introduction that discusses the examined material and the methods used in the taxonomic study, a chapter is devoted to the characters that led to the partition of genus Trizopagurus, namely the shape of the cephalothoracic shield, ornamentation of thoracic appendages, organization of the pleopods, and the stridulatory structures. Thèse structures, described and compared in the following chapter, are of particular interest since they can be used to define the three gênera. Their homologies indicate an evolutionary trend from Trizopagurus via Ciliopagurus to Strigopagurus and the three gênera are studied following the order of this cline. The systematic section first gives an account on the current status of the Diogenidae, recently enriched with four gênera. The characters of each genus are tabulated and their comparison used to define some groupings. In most cases, the genera brought together in a same group show marked differentiations and are not closely related. However, the three genera presently studied form a coherent unit, especially on account of the stridulatory structures, which are peculiar and unique, not only within the family, but in ail decapods. An identification key is provided for ail known genera of Diogenidae.The systematic treatment of the three studied gênera comprises references, diagnosis and définitions, together with remarks on the affinities of the included species. Key s for species identification are provided. For each species are given références, a full synonymy, a list of examined material, informations on type spécimens, a description and an account of variations, when enough spécimens are available. In the remarks, the main distinctive morphological features are pointed out and compared with those of related species. Are also mentioned the size distribution by sex, the identified inhabited shells, and the distribution. Trizopagurus Forest, 1952, is characterized by the relatively weak development of the stridulatory elements, which are fewer, less differenciated and grouped in less distinct patches than in the other two genera. The ornamentation of the chelipeds consists of slightly projecting and rounded teeth or tubercles, in front of which short setae (ciliae) are located in semicircular rows. In both sexes, there are four biramous pleopods on the left side of the abdomen, the last one smaller and never oviferous in the female. The three species inhabit shallow water, usually in the tidal zone. T. magnificus (Bouvier, 1898) belongs to the tropical fauna of the eastern Pacific. T. melitai (Chevreux & Bouvier, 1892) and T. rubrocinctus Forest & Raso, 1990, are both from the tropical northeastern Atlantic. In Ciliopagurus gen. Nov., the stridulatory structures are looking like fine, corneous, parallel rods, grouped in several neatly separated patches, which are homologous in the different species. The first three thoracic legs are ornamented by transverse ciliated striae, with much longer setae in some species. There are four unpaired biramous pleopods in both sexes, the last one equal to the others and always oviferous in the female. The species can be separated into two groups, according to whether the ridges on the carpus and propodus of chelipeds, along the transverse striae, are smooth or tuberculated-denticulated. The first group includes eight species : C. strigatus (Herbst, 1804), C. îricolor sp. Nov., C. krempfi (Forest, 1952), C. caparti (Forest, 1952), C. albatrossi sp. Nov., C. shebae (Lewinsohn, 1969), C. macrolepis sp. Nov. Et C. liui sp. Nov. The second group comprises also eight species : C tenebrarum (Alcock, 1905), C. haigae sp. Nov., C. hawaiiensis (McLaughlin & Bailey-Brock, 1975), C. pacificus, C. plessisi, C. major, C. alcocki and C. babai spp. nov. The genus Ciliopagurus, which is widely distributed, includes one species, C. caparti, from the tropical eastern Atlantic. All others are from the tropical Indo-West Pacific, from the Red Sea and southeastern Africa to Japan and the Hawaiian and Marquesas Islands. The bathymetry range is highly variable. In the first group two species are restricted to very shallow water, mostly from the tidal zone. The other ones are distributed from 50 to 120 m, except for the eurybathic C. krempfi, which has been collected between 10 and 300 m. The second group is mostly présent from 120 to 480 m, one species reaching probably a greater depth. The genus Ciliopagurus gen. Nov. Also includes a fossil pagurid from the Middle Miocène, previously known as Dardanus substriatiformis (Lorenthey) and related to the species of the second group.The genus Strigopagurus gen. Nov. Is provided with the most differentiated and accomplished stridulatory structures. They consist of relatively thick corneous rods, arranged in strongly individualized patches, the larger of which appearing as distinctly channelled plates. The carpus and manus of the chelipeds are covered dorsally with strong teeth that end in a thin corneous spine. Thinner corneous teeth are also present on the two following appendages. As usual within the Diogenidae, except Paguristes and Paguropsis, there are no appendages on the first abdominal segment. In the female, the four pleopods are unpaired and biramous, the last one being only partially oviferous. But the second abdominal segment of the maie is usually supplied with a pair of pleopods, which, according to the species, are modified or not as gonopods ; the following three appendages are unpaired and biramous. The five species can be separated into two groups. The first comprises two species without a differentiation of the paired maie pleopods, i. e. S. strigimanus (White, 1847) and S. elongatus sp. nov. The three species with differentiated gonopods, S. bilineatus, S. boreonotus and S. poupini spp. nov. Form the second group. Strigopagurus gen. nov. Is not as extensively distributed as Ciliopagurus gen. nov., being found only from the eastern Indian Océan to Japan and Polynesia. The genus is not strictly tropical, since the two species with undifferenciated pleopods inhabit the southern Australia. One of the other three species is known only from Queensland and another from Polynesia. The last one, present in eastern Indonesia, New Caledonia, the Philippines and Japan, is the only species of the genus spreading north of the Equator. The species of the first group inhabit relatively shallow water, usually from a few to about a hundred meters. The other species are all present at about 250 m, but one of them, the most widely distributed, is still relatively common to 500 m. Finally, a general account of the geographic and bathymetric distribution of genera and species is given and illustrated with maps and a table.

Résumé [+] [-]Laurentaeglyphea, a new genus for the second recent species of Glypheid recently discovered. (Crustacea Decapoda Glypheidae). In 1975, a recent member of a large group of Crustacea Decapoda was described as Neoglyphea inopinata Forest & de Saint Laurent, until now only known as fossils and presumed extinct since the Eocene. The only known specimen had been collected in the Philippine waters, in 1908, at a depth of 200 m. During the next years, three oceanographical expeditions gave more adult specimens, allowing complete study of the species. From its morphology, it appeared that the status attributed to glypheids in the past in the classification of Decapoda Crustacea was quite erroneous. This group, until then considered as related to Palinurids (rock lobsters) was in fact much closer to Astacids (lobster, crayfish, etc.). In 1982, N. inopinata was recorded from the other side of Equator, from the Timor Sea. In October 2005, a second living species of glypheid was discovered southwest of New Caledonia. It was named Neoglyphea neocaledonica B. Richer de Forges, 2006. However, important and significant differences set apart the two species, especially the ornamentation of the cephalothorax, the conformation of the cephalic part and the proportions of epistom and thoracic appendages, being much more robust. It seems justified to establish, for the more recently described species, a new genus, Laurentaeglyphea, much closer to fossil forms.

Résumé [+] [-]Until recently, the family Glypheidae (Decapoda, Reptantia) was known from fossils only, and consequently presumed extinct for 50 million years. However, in 1975 scientists of the Museum National d'Histoire Naturelle in Paris recognized a Recent specimen as belonging to this family. The specimen had been collected in the Phillippines in 1908 at approx. 200 m depth, and had remained unidentified in the collections of the Smithsonian Institution, Washington, D.C., since. That same year, the species was described as Neoglyphea inopinata Forest & de Saint Laurent, thus testifying the actual persistence of the group in today's marine fauna. Three expeditions in the same region, in 1976, 1980, and 1985, yielded another 20 specimens, all caught alive. The subsequent study of those specimens would indicate that the phylogenetic position assigned to the glypheids until then had, in fact, been erroneous. The same applied to the other mesozoic families included in the superfamily Glypheoidea. The glypheoids had usually been placed next to the Scyllaridae and Eryonidae in the infraorder Palinura, and been considered probable ancestors of part of the remaining Decapoda Reptantia. However, their similarities would come out to result rather from analogous resemblances than from actual morphological affinities. In fact, after comparison of the principal characters of the three groups, we have been able to confirm that the Glypheoidea did not exhibit any true relationship with the two others. In contrast, they proved to be closer to the Astacidae and could, eventually, be ranked with those in the same infraorder. A number of recent publications, largely by palaeontologists and based in part on cladistic as well as molecular analyses, have lately supported this point of view. They completely reject the inclusion of the glypheoids in the Palinura, corroborate their affinities with the Astacidea, and exclude the possibility that they would represent a primitive group from which other Reptantia could have evolved. The lineage of the Glypheoidea most probably appeared in the Permian-Triassic, prospered in the Jurassic, and subsequently declined from the Cretaceous to the Eocene. It is apparent that the group has not become extinct during that era, but has silently persisted, without leaving fossil traces, with at least two representatives in today's living world. Indeed, a second species of glypheid has recently been discovered in the southwestern Pacific. Though described under the name Neoglyphea neocaledonica, it shows such differences with N. inopinata that I have established a new genus for this species, Laurentaeglyphea, which is even closer to the glypheids known from the Mesozoic and the Eocene.

Résumé [+] [-]In recent years, a range of operculate sixth abdominal tergite types of pylochelid and parapylochelid hermit crabs (Anomura, Paguroidea) have been recorded from Upper Jurassic (Oxfordian and Kimmeridgian) strata in southern Poland and southern Germany. Here we add two new genera (Parapylochelitergites, Paguritergites) and four new late Early Cretaceous species (Parapylochelitergites pustulosus, Pylochelitergites alatus, Pylochelitergites rugosus and Paguritergites yvonnecooleae) from Navarra, northern Spain. In the reefal limestones at Koskobilo quarry near Alsasua, of late Albian age, the number of sixth abdominal paguroid tergite taxa approximates that of paguroid carapace types. Thus, linking fossil paguroid carapaces to tergites can now be attempted. Assemblages of symmetrical hermit crabs (parapylochelids and pylochelids) in reefal settings appear to have changed drastically from the late Albian onwards, with asymmetrical forms (Diogenidae, Paguridae) becoming predominant.

Résumé [+] [-]During fieldwork in 2009 at Ternate, Indonesia, a pair of a pontoniine shrimp species belonging to the genus Conchodytes was collected from a bivalve mollusk of the genus Spondylus. This constitutes the first record of a species of the genus Conchodytes associated with a spondylid host. The specimens can be distinguished from other known Conchodytes species based on both morphology and colour pattern. Its COI barcode however, strongly resembles those obtained from three specimens of C. meleagrinae and is nested in the C. meleagrinae clade of the reconstructed phylogeny. Based on morphology and colouration only the specimens associated with the Spondylus bivalve would have been described as a species new to science. The modest conflicting molecular data have lead the authors to fully describe and figure the Spondylus associated specimens and compare them with the Pinctada associated specimens. Based on the present information it is decided not to give the Spondylus associated specimens the status as a distinct species but regard them as host-related (colour)morph of Conchodytes meleagrinae.

Résumé [+] [-]A single ovigerous female specimen of marine shrimp of the family Palaemonidae collected from Madang Province, N.E. Papua New Guinea, was recognized as a representative of a new genus and species. Due to the presence of a sternal thoracic process, 3 pairs of posterior telson cuspidate setae, and the simple ambulatory dactyli, as well as the lack of branchiae on the two posterior maxillipeds, the new species clearly belongs to the assemblage of primarily free-living palaemonid taxa surrounding the speciose genera Cuapetes and Palaemonella. As the specimen possesses a short leaf-like rostrum,slender second pereiopods with small chelae similar to and not noticeably longer than the first pereiopods and very slender simple ambulatory dactyli, the specimen is without parallel within this assemblage and clearly represents a new genus. Its position within the Cuapetes/Palaemonella lineage of genera is also confirmed by a molecular comparison. The specimen is described and illustrated as a new genus and species.

Résumé [+] [-]The polychelids are large, uncommon, primitive decapods that inhabit the depths of the world oceans down to 5000 m, between latitudes 50°N and 55°S. A study of major deep-sea collecdons led to a revision of the family. All genera and species are redescribed and extended synonymies given. Two new genera are established: Cardus, for Polycheles crucifer (Thomson, 1873) and Homeryon, for Polycheles asper Rathbun, 1906 and a new species, H. armarium. The genus Pentacheles Bate, 1878, is revived to include polychelids in which the epipod on third maxilliped is longer than the ischium: P. gibbus Alcock, 1894, P. laevis Bate, 1878, P. obscurus Bate, 1878, P. synderi (Rathbun, 1906) and P. validus A. Milne Edwards, 1880. Stereomastis Bate, 1888 is considered a synonym of Polycheles Heller, 1862. Willemoesia Grote, 1873 is retained with but four species: W. forceps A. Milne Edwards, 1880, W. inornata Faxon, 1893, W. leptodactyla (Willemoes-Suhm, 1875), and W. pacifica Sund, 1920. In all, thirty-two species are recognized, including six new species. The bathymétrie and geographic ranges are amended and discussed. A key to the genera and species of the family is provided.

Résumé [+] [-]A new genus, Ancylodactyla n. gen., is established for two deep water species excluded from Praebebalia Rathbun, 1911, P. elongata Zarenkov, 1969, and P. elata Zarenkov, 1994, and for Randallia nana Zarenkov, 1990, provisionally assigned to Randallia s.s. A study of the extensive collection of leucosiid crabs made by French expeditions to the Indo-Pacific Ocean has increased the known geographic and bathymetric ranges of these species. The new genus is distinguished from Praebebalia and from Randallia s.s. in having male abdominal somites 3-6 fused, and the second male pleopod longer than first pleopod. The species are redescribed, fully illustrated, synonymies are discussed, and a key for their identification is provided.

Résumé [+] [-]The collection of deep-sea blind lobsters (Polychelidae), comprising eight species in three genera: Pentacheles Spence Bate, 1878, Polycheles Heller, 1862, and Stereomastis Spence Bate, 1888, is significant for although these species had been recorded in adjacent regions, prior to the BIOPAPUA expedition they have not been recorded from the Bismarck and western Solomon seas. The feasibility of seabed ore mining adds a sense of urgency to the exploration and analysis of the benthic biodiversity of a unique, barely explored region up for destructive exploitation.

Résumé [+] [-]The phylogenetic relationships and evolutionary processes within the subfamily Pontoniinae, a speciose group of shrimps with diverse lifestyles (free living, semi-symbiotic and symbiotic) inhabiting the coral reefs of tropical oceans, are an interesting and undeveloped subject of study. In this work, two mitochondrial ribosomal genes (12S rRNA and 16S rRNA) and two protein-coding nuclear genes (Histone 3 and the sodium–potassium ATPase a-subunit) were employed to reconstruct the phylogenetic relationships of 42 genera and 101 species within Pontoniinae. Compared to previous studies, ten additional genera were shown to be monophyletic groups, and the genera Dactylonia and Periclimenaeus were shown to be paraphyletic. The shallow-water crinoid-associated pontoniines were divided into several groups which were mostly consistent with the morphological analysis. The studied bivalve-associated taxa exhibited ancestries that were traceable to different lineages, and two groups could be distinguished: Anchiopontonia + Conchodytes and Anchistus. The similar situation occurred in other echinoderm-associated pontoniines. These results suggest that pontoniines sharing the same hosts may have different evolutionary origins resulting from multiple intrusions of their hosts by morphologically plastic ancestral groups.

Résumé [+] [-]Chelarctus Holthuis, 2002 is widely distributed throughout the Indo-West Pacific, but its biogeographic patterns are unknown because Southern Hemisphere areas, such as the Coral Sea, remained poorly explored. Recent cruises organized by the Muséum national d'Histoire naturelle of Paris and the Australian Institute of Marine Science allowed the molecular identification of Crenarctus crenatus (Whitelegge, 1900), Chelarctus aureus (Holthuis, 1963) and Chelarctus crosnieri Holthuis, 2002 phyllosomae. The Coral Sea C. crenatus larvae are identical to stages IX and X of Scyllarus sp. Z, described in detail by Webber and Booth (2001). Descriptions of phyllosoma stages VI, IX and X of Ch. aureus and stages IX and X of Ch. crosnieri are also presented here. Morphological differences between Crenarctus and Chelarctus larvae are established for the first time and previous misidentifications in the literature are re-assessed.

Résumé [+] [-]Females and larvae of an ascothoracid crustacean, Endaster hamatosculum gen. et sp. nov., are described. They live in large cysts in arms of the sea-star Zoroaster carinatus philippinensis Fisher, 1916. The new genus belongs to the previously monotypic Ctenosculidae and is distinguished from Ctenosculum Heath, 1910, primarily by its wider than long, ellipsoidal carapace, and features of the thorax. The peculiar nauplii have well developed but uniramous antennae and mandibles, and the sexes are separable by the end of naupliar development. The first ascothoracid larva is more generalized than the same stage of other echinoderm-infesting ascothoracids. Endaster's possible utility as a model of the evolutionary grade between Ctenosculum and Ulophysema Brattstrom, 1936, is discussed.

Résumé [+] [-]The first scanning electron microscopical (SEM) study of a morphologically generalized ascothoracidan crustacean is presented. The extemal morphology of a female Waginella metacrinicola (Okada), ectoparasitic on a pentacrinid stalked crinoid, Metacrinus rotundus Carpenter from Japan, is illustrated using SEM. Several kinds of gland openings on the fiat, ventral side of the carapace are described. The inner wall of the large anteroventral pore on each carapace valve possesses lamellar ridges that bound a large number of small gland openings. Two anterior lattice organs (cardic organs) are found on each valve. The so-called second antenna or antennavestigial eyestalk complex does not arise from the cephalon proper, but from the mantle lateral to the antennule, and it most likely incorporates the extemal part of the organ of Bellonci complex. Records of W. metacrinicola and W. axotremata Grygier infesting metacrinine pentacrinids collected by recent French expeditions to the Philippines and New Caledonia are listed. The former species is reported from Metacrinus musorstomae Roux for the first time, and the latter from M. levii Cominardi, M. serratus DOderlein, and Saracrinus nobilis (Carpenter) for the first time. Waginella axotremata is also reported from northem Australia, infesting S. nobilis, and southeastem Australia, infesting M. cyaneus H.L. Clark. This species apparently uses its raspy, awl-like mandibles, drawings of which are presented herein, to drill ho les in the cirri of its host; such drill-holes are proposed as potential trace fossils for studying the history of crinoid-ascothoracidan associations. The apparent absence of ascothoracidan parasites on other genera of Pentacrinidae suggests that the association may be no older than the Miocene. The possible synonymy of W. metacrinicola and W. axotremata is discussed on the basis of morphology, depth distribution, and biogeography, but is not resolved. Crinoidoxenos Blake, 1933 is revealed as a potential senior synonym of Waginella.

Résumé [+] [-]Hypertrophied corallites with irregular septal patterns in the Hawaiian deep-water coral Madrepora kauaiensis Vaughan were interpreted 30 yr ago as possible neoplasms, and this idea has persisted in comparative oncological literature. Many colonies of Madrepora oculata L. with similarly modified corallites are recorded herein from 233 to 604 m depth off northwestern Australia and Japan, In the Formosa Strdit, and in the Banda and Araiura Seas, Indonesia. The affected corallites have a hollow space beneath the interrupted columella. Most specimens had been dried and bleached, leaving no tissue but in some alcohol-preserved Indonesian specimens this cavity was occuped by endoparasitic petrarcid ascothoracidan crustaceans. These are described herein as Petrarca madreporae Grygier, new specles, which is characterized by a posterior lobe on each carapace valve, poorly armed mouthparts, and a bifid penis with fixed rami. The validity of the diagnosis of the petrarcid genus Zibrowia Grygier, 1985 is questioned. The abnormal corallites are provisionally reinterpreted as an unusual kind of petrarcid 'internal gall'.

Résumé [+] [-]Previous Australian records of Ascothoracida are summarised. In the Synagogidae, three new species of Gorgonolaureus Utinomi are described from primnoid (Pterostenelia plumatilis (Rousseau», paramuriceid (unidentified), and gorgoniid (Eunicelia sp.) gorgonacean hosts off Western Australia, Vietnam, and New Caledonia, respectively. The first two species are from unusually shallow depths, 80 to 100 m, the third from bathyal depths. Flatsia n.gen., with one species from 73 to 82 m depth off New South Wales, host unknown, is provisionally assigned to the Synagogidae. In the Lauridae, two new species of Baccalaureus Broch are described from the subtidal zoanthid Isaurus tuberculatus Gray on the Great Barrier Reef and the solitary zoanthid Sphenopus marsupialis Steenstrup at several shallow sites (40-86 m) off Queensland and Western Australia and in the Andaman Sea. In the Petrarcidae, morphological and ecological notes on Petrarca okadai Grygier infesting the coral Heteropsammia cochlea (Spengler) at Lizard Island, Queensland, are presented. Two new species of Petrarca Fowler are described infesting the solitary coral Fungiacyathus sp. off Moreton Bay, Queensland, and the hermatypic reef coral Turbinaria reniformis Bernard at Lizard Island. An unnamed species of Petrarca from the solitary coral Anthemiphyllia dentata A1cock collected between 110 and 350 m off Queensland is partly described. A list and some photographs of other new records of galls caused by petrarcid ascothoracidans in various Indo-Pacific sc1eractinians, especially Turbinaria spp. And other dendrophylliids, are presented.

Résumé [+] [-]The first zoeal stages of the galatheids Neonida grandis, Agononida squamosa and Munida javieri, and the chirostylids Eumunida annulosa and E. capillata are described and illustrated from laboratory-hatched material obtained from ovigerous females collected from south western Pacific. The morphologies of the first zoeae are compared with the same larval stage of other known anomuran species. The larval characters of Agononida squamosa and Neonida grandis are similar to those described for Agononida incerta. Munida javieri exhibits features not present in other described species of Munida such as the setation of the endopod of the maxillule and the antennal morphology. Eumunida annulosa and E. capillata do not show abbreviated development as in other described chirostylids such as Uroptychus and Gastroptychus, and its larval morphology is equivalent to the first stage of galatheid zoeae. However, many morphological characters of E umunida species are typically pagurid, such as the two terminal plumose setae of the antennal endopod, the three-segmented endopod of the maxillule, the posterior margin of the carapace without spines, and the scaphognathite with 5 plumose setae and without a posterior lobe.

Résumé [+] [-]Two species of the genus Sphenocarcinus A. Milne Edwards 1875, with a single rostrum exist in the Indo-Pacific and they are principally only known by. their original description: S. cuneus (Wood Mason 1891) and S. atworm Alcock 1899. Each species is herewith redescribed, based on the examination of the types: TWO new species are established. S. difficils sp. nov., represented by numerous specimens from Madagascar (ORSTOM collection), proved to be an intermediate species between S. G U ~ ~ ZaLnSd S. aurorw. S. pinocChio sp. nov., collected in the Makassar Strait, Indonesia (mission Corindon II), is characterized by its very long and strongly curved rostruni. One nmale specimen, also collected in the Makassar Strait, probably modified by a sacculinid parasite, and with a more curved, snub rostrum, can be regarded as an unusual form of S. pinocchio sp. nov. A key of the four Indo!Pacific Sphenocarcinus with a single rostruni is presented.

Guinot D. & Quenette G. 2005. The spermatheca in podotreme crabs (Crustacea, Decapoda, Brachyura, Podotremata) and its phylogenetic implications. Zoosystema 27(2): 267-342
Résumé [+] [-]The thoracic sternum of the primitive crabs (Podotremata Guinot, 1977) is strongly modified in females at the level of the sutures 7/8, separating the last two sternites, which corresponds to a secondary specialization of the phragmae 7/8. Thus a paired spermatheca has developed, which is intersegmental, internalized and independent of the female gonopores on the coxae of the third pereopods. This is unique to the Podotremata, being completely distinct from the eubrachyuran seminal receptacle. The spermatheca is reviewed in all members of the Podotremata, in its external aspect and internal structure. Among the Dromiacea, a spermathecal tube becomes specialized in the Homolodromiidae, Dromiinae, and Hypoconchinae, while it is absent in the Dynomenidae and Sphaerodromiinae, suggesting that the Sphaerodromiinae are basal to the Hypoconchinae + Dromiinae and that the Dynomenidae are basal to the remaining dromiaccan families. The phylogenetic implications are discussed, confirming the distinction of two basal clades, Dromiacea and Homolidea, the peculiar organization found in the Cyclodorippidae, Cymonomidae and Phyllotymolinidae, and the special condition of the Raninoidea. The paired spermatheca proves to be the strongest synapomorphy of the Podotremata, including two Cretaceous families. Hypotheses on female sperm storage and functioning of the spermatheca, on male sperm transfer and the role of gonopods in insemination, and on the modalities of fertilization are included. New data on the axial skeleton are provided. The study of the spermatheca, which has considerable systematic value in decapod phylogeny, leads to a discussion of the monophyly of the Brachyura, taking into account the paleontological data.

Résumé [+] [-]A re-evaluation of the Dynomenidae Ortmann, 1892, on the basis of morphological characters, allows four subfamilies to be recognised, viz. Acanthodromiinae n. subfam., Dynomeninae Ortmann, 1892, Metadynomeninae n. subfam., and Paradynomeninae n. subfam. Sequences of character states for each homologous character (morphocline) show a similar polarity. The Acanthodromiinae n. subfam. exhibits a plesiomorphic condition, both in body shape and fronto-orbital disposition as well as in the condition of the thoracic sternum, abdominal holding mechanism and gill structure. Both the Metadynomeninae n. subfam. and Dynomeninae are more advanced, the latter being more “carcinized” and the most derived. The Paradynomeninae n. subfam. evolved a specialised frontal and buccal region, by forming a projecting “face”. The family Dynomenidae, which presently comprises merely five extant genera and 21 species, but with a worldwide distribution, is amongst the most ancestral brachyuran families, with a good fossil record from the Late Jurassic onwards. A few fossil genera such as Kromtitis Müller, 1984, and Kierionopsis Davidson, 1966, appear to conform to the Paradynomeninae n. subfam. A key to the subfamilies of extant Dynomenidae is provided.

Résumé [+] [-]The genus Sphenocarciilus A.Milne Edwards, known by 16 Indo- Pacific species with a rostrum which is either single (four species) or double (12 species), is widened by the discovery of a new species with a bifurcated rostrum, collected between 300-460 m, by the 'Vauban', in the north of New Caledonia, i,e. Splenocarcinus fnamrnatus sp.nov. Two other species of that genus, S.orbiculatus Guinot & Richer de Forges and S.stuckiae Guinot & Richer de Forges, had been previously recorded in the same area, near the island of Pines (south of New Caledonia).

Résumé [+] [-]Some very interesting deep-sea material was collected during the MUSORSTOM expéditions 1 (1976), 2 (1980) and 3 (1985) in the Philippine waters and the CORINDON 2 expédition (1980) in the Strait of Makassar. We first describe the numerous species brought back, both uncommon and new. This account is not intended to be a taxonomic revision of the Indo- Pacific species, which may belong either to the genus Trichopeltarion A. Milne Edwards, 1880, or to the genus Trachycarcinus Faxon, 1893. Both of these genera are attributed to the superfamily Corystoidea Samouelle, 1819, the revision of which is in progress. With Trachycarcinus and Trichopeltarion, the monospecific genus Pteropeltarion Dell, 1972, from New Zealand, forms a natural group alsqo with the genus Podocatactes Ortmann, 1893, endemic to Japan, and with the American genus Peltarion Jacquinot, 1847. We can only say here that they belong to the Heterotremata Guinot, 1977. One problem was encountered, because the criteria used to separate the two Indo-Pacific genera Trachycarcinus and Trichopeltarion are morphotypal ; the fact that the type-species of these genera originated from American water complicates matters. Ail the species reported here are attributed to the genus Trachycarcinus alone, without anticipating on a future study of the phylogenetic relationships and taxonomic status of the above-mentioned genera. Two species are discovered for the second time : Trachycarcinus alcocki (Doflein) and T. ovalis (Anderson). All the others are new : Trachycarcinus aff. ovalis, from the Philippines, which is only represented by a female ; T. moosai sp. nov. and T.foresti sp. nov., from the Philippines, and a close species, provisionally named Trachycarcinus aff. Delli.

Résumé [+] [-]This paper contains a study of the genus Psopheticus based on collections from the area around Madagascar (leg. Crosnier & Cleva, Benthedi Exp.); from Réunion (Marion-Dufresne 1982, MD32); from the Philippines (MUSORSTOM 1-3), from the Makassar Strait (Corindon 2, 1980); and from New Caledonia (Biocal and Musorstom 4, 1985). The type species, P. stridulans Wood-Mason, 1982, is redescribed, based on a topotype, from tyhe Andaman Sea. In addition, the genus contains P. insignis Alcock, 1900 and P. hughu Rathbun, 1914, both of which are redescribed, and P. vocans Guinot, 1985. Three new species are erected : P. crosnieri from Madagascar ; P. musicus from the Philippines ; and P. insolitus from the Makassar Strait. Specimens previously reported as P. stridulans by Guinot, from Réunion, have been reexamined and are considered of uncertain status but close to P. stridulans. A key is provided for identification of the species. The armature of the ambulatory legs was found to be a reliable and complex specific character, indepedant of sex and age, and is described for each species. A large series of P. insignis evidenced pronounced allometry in the growth pattern of the anterolateral edge of the carapace and a sexual dimorphism with longer chelipeds in the male.

Résumé [+] [-]Poupinia hirsuta gen. nov., sp. nov., est décrit d'après deux spécimens, un mâle et une femelle ovigère de 50 mm de long environ, pris au casier à 440 m de profondeur en Polynésie, îles de la Société (Raiatea). Le genre Poupinia, qui se situe dans le plésion des Brachyoures parmi les Podotremata (orifices génitaux femelles et mâles coxaux), à l'écart des Dromiacea, prend naturellement place dans la section des Archaeobrachyura. La superfamille des Homoloidea peut accueillir le genre Poupinia en raison de ses traits typiquement homoliens : PS seule subdorsale (et non aussi P4) ; morphologie du sternum thoracique, divisé transversalement en deux parties par la suture 6/ 7, complète ; présence d'une paire de spermathèques tégumentaires externes chez la femelle ; abdomen mâle et femelle de 7 segments libres ; main tien du pléon contre le plastron par un dispositif de rétention double; une paire de pléopodes (réduits) sur le premier sternite abdominal de la femelle ; appendices sexuels mâles 1 et 2 avec coxa et basis encore distincts; Pli mâle complètement enroulé mais avec une très large ouverture basale.

Résumé [+] [-]Preliminary results concerning three families of the Brachyura Podotremata are presented. In the Dynomenidae, thanks to recent captures in New Caledonia, the genus Paradynomene Sakai is compared to other members of the family. Described or confirmed in the Homolodromiidae are : the presence in the maie of abdominal segments frequently provided with rudimentary pleopods on somites 3-5 and extended by inclined pleura ; in both sexes, the absence of vestigial uropods intercalated dorsally and their replacement by a small platelet inserted ventrally. Three new taxa are described : Homolodromia kai sp. Nov. And Dicranodromia karubar sp. Nov. From Indonesia, D. foersteri sp. Nov. From Chesterfield Islands. The placement of the family Dakoticancridae, only known from North American Cretaceous fossils, in the Podotremata is confirmed (presence ofonepair ofspermathecae), and the numerous peculiarities of the group are discussed.

Résumé [+] [-]The homolid spermatozoon, as exemplified by Homola sp., Paromola sp. and Paromola petterdi, differs markedly from spermatozoa of crabs of the Heterotremata-Thoracotremata assemblage but agrees with the sperm of dromiids, in the strongly anteroposteriorly depressed acrosome (apomorphy?) and the capitate form of the perforatorium (a major synapomorphy seen nowhere else in the Crustacea). These similarities support inclusion of the Dromiidae and Homolidae in a single grouping, the Podotremata. The homolid perforatorium differs from that of dromiids in the autapomorphic spiked-wheel form of the anterior expansion. Homolid spermatozoa show nuclear arms symplesiomorphic of all investigated crabs (small or questionably sometimes absent in Dromiidae), and corresponding loss of purely microtubylar arms seen in other reptants. Homolid sperm agree with those of dromiids (synapomorphy?), raninids, higher heterotremes and thoracotremes (homoplasies?) but differ from lower heterotremes, in lacking microtubules in the nuclear arms. A posterior median process of the nucleus in homolids, not seen in dromiids, is shared with anomurans and lower heterotremes. No featlires in the ultrastructure of homolid or dromiid sperm have been detected which associate them exclusively with either the Raninidae or the heterotreme and thoracotreme Brachyura.

Résumé [+] [-]Crustacea Decapoda Brachyura : Revision of the family Homolidae de Haan, 1839. Collections made by scientists from ORSTOM and during French expeditions, resulting from the cooperation of ORSTOM and the Muséum national d'Histoire naturelle, in the upper bathyal zone of the Indo-West-Pacific (Madagascar, Seychelles, Indonesia, the Philippines, New Caledonia, Chesterfield Islands, Wallis and Futuna Islands) have accumulated abundant crustacean material. We have added to it the collections by various Australian, German and Soviet expeditions in regions poorly explored until now. We have studied also specimens taken by deep traps near atolls in French Polynesia and in french Anfilles. We have also been able to examine almost all the Homolidae deposited in the large museums of the world, reference and unidentified collections, and thereby to prepare an account of the Hawaiian, Japanese, Indian, African, South African and American faunas. From all these collections it has been possible to revise and restructure the Homolidae world-wide. Examination of all type specimens has been necessary, as has that of all specimens mentioned in the literature; practically all references and all identifications have been verified. The Homolidae comprise now 14 genera, studied in terms of their phylogenetic affinities : eight genera already known (Homola Leach, Paromolopsis Wood-Mason, Paromola Wood-Mason, Latreillopsis Henderson, Homolochunia Doflein, Hypsophrys Wood-Mason, Homolomannia Ihle, Homologenus A. Milne Edwards) ; two former subgenera elevated to generic rank (Homolax Alcock, Moloha Bamard) ; and four new genera (Dagnaudus, Ihlopsis, Yaldwynopsis, Gordonopsis). Until now quite poor in species, the family now contains in the whole 57 species : it is increased by 17 new species ; in addition, about ten uncertain species are leaven apart. In the cases of two genera considered amphi-Atiantic, Homola and Homologenus, a new taxon is described ; Homola minima sp. Nov. Is separated from H. barbata (Fabricius), typically Mediterranean ; and Homologenus boucheti sp. Nov. Is separated from H. rostratus (A. Milne Edwards), from the American Atlantic. Three other new species are added to Homola : H. eldredgei, H. coriolisi and H. ranunculus. The genus Paromola is confined to some species close to P. cuvieri (Risso) and two new taxa are added : P. bathyalis and P. crosnieri. Six species are attributed to Moloha of which the former is the type species M. alcocki (Stebbing), another one the ancient Latreillopsis major of KUBO (validated) ; it is augmented by two new species, M. alisae and M. grandperrini, and also The genus Latreillopsis receives three new species : L. daviei, L. cornuta and L. antennata. The new genus Ihlopsis includes, besides I. multispinosa (Ihle) (formely in Latreillopsis), one new species, I. tirardi. A third species, H. gadaletae, is added to Homolochunia. Only one species is added to Hypsophrys, H. futuna, but the genus is certainly more diverse. Three new species, H. boucheti, H. levii and H. wallis are described in the genus Homologenus. The genus Homolax, poorly known, is well defined. For each genus adiagnosis, an illustration of the principal characteristics and homologies, plus a key to all species are given. Each genus has been strictly redefined with respect to its type species and to all its species. For the numerous poorly known species a description or summary of characters differentiating it from the nearest taxon is presented H has been made by a synthetic study of all important morphological criteria ; we have reviewed all the principal arrangements and structures of Homolidae to understand their homologies and reach rigorous the nomenclature of the grooves and ornamentation of the carapace which have been often confused in the past. Some phylogenetic hypotheses are briefly presented. The place of the Homolidae in Homoloidea is commented on with a key to the three members of the superfamily. Short remarks, which will be completed in another work, on fossil representatives are outlined. Lastly, geographic and bathymétrie distribution of the genera and species are discussed. Each species is represented often with drawings and always by several photographs.

Comparative Spermatozoal ultrastructure of the three dromiacean families exemplified by Homolodromia kai (Homolodromiidae), Sphaerodromia lamellata (Dromiidae) and Dynomene tanensis(Dynomenidae) (Podotremata: Brachyura). JOURNAL OF CRUSTACEAN BIOLOGY 18(1): 78-94
Résumé [+] [-]The monophyletic Dromiacea, including Sphaerodromia lamellata, Homolodromia kai, and Dynomene tanensis, here studied, have the following characters: (1) operculum perforate, but lacking the thoracotreme apical button; (2) opercular projections into the subopercular material, diagnostic of homolids, absent; (3) operculum discontinuous with the capsule, unlike raninoids; (4) operculum moderately thick, not extremely thin as in the cyclodorippoids Tymolus and Xeinostoma; (5) operculum not extremely wide, contrasting with the great width in cyclodorippoids; (6) periopercular rim and (7) accessory opercular ring absent, being variably present in eubrachyurans; (8) subopercular protuberance through operculum well developed (synapomorphy), weak in homolids; (9) true acrosome ray zone absent; (10) peripheral border of outer acrosome zone border not ragged, unlike some xanthoids; (11) anterolateral pale zone of acrosome contents present (autapomorphy); (12) xanthid ring absent; (13) subacrosomal chamber or perforatorium extending preequatorially, unlike Ranina ranina; (14) head of perforatorium bilateral (autapomorphy); (15) corrugations of the wall of the perforatorial chamber absent; (16) centrioles apparently absent; (17) posterior median process of the nucleus absent; (18) thickened ring (typical of Eubrachyura) absent; (19) concentric lamellae (typical of Thoracotremata) in the outer acrosome zone absent; (20) capsular chambers absent; and (21) capsular flange absent, unlike Ranina ranina and Raninoides sp. Spermatologically Sphaerodromia lamellata appears closer to the dynomenid Dynomene tanensis than it is to the mutually paraphyletic Dromidiopsis edwardsi and Stimdromia lateralis. The spermatozoon of Homolodromia kai (Homolodromiidae) shares a striking putative synapomorphy with Paradynomene tuberculata: a flange-like lateral extension of the lower acrosome zone; both species appear to lie within a dromiid clade. Neither the Dromiidae nor the Dynomenidae appear monophyletic spermatologically. The spermatozoal evidence is discussed in the light of a brief review of nonspermatozoal morphology. General morphology and spermatozoal ultrastructure both strongly endorse monophyly of the Dromiacea.

Résumé [+] [-]All Jurassic brachyuran taxa known to date are based solely upon dorsal carapaces, and only a limited number of Early and mid-Cretaceous crabs retain ventral parts. Therefore, all Jurassic taxa and many forms from the first half of the Cretaceous are carapace-based entities. All of them are considered to be “dromiaceans”, podotremes to be precise. The recent discovery of an exceptionally well-preserved male crab from the Upper Cretaceous (lower Cenomanian) of Chiapas (Mexico), Archaeochiapasa mardoqueoi Guinot, Carbot-Chanona & Vega, 2019, at first sight of a podotreme nature, has allowed a detailed description of its thoracic sternum and pleon, which revealed that it was actually a typical eubrachyuran, in need of a new family, Archaeochiapasidae Guinot, Carbot-Chanona & Vega, 2019. This has brought back to life one of my earlier ideas about the possible non-podotreme nature of certain enigmatic Late Jurassic and Cretaceous Brachyura previously placed in various “dromiacean” (i.e., podotreme) families and superfamilies. My investigations have led the me to formulate the present hypothesis that the extinct families Bucculentidae Schweitzer & Feldmann, 2009 (currently assigned to the Homolodromioidea Alcock, 1900), Lecythocaridae Schweitzer & Feldmann, 2009, Glaessneropsidae Schweitzer & Feldmann, 2009, Nodoprosopidae Schweitzer & Feldmann, 2009, and Viaiidae Artal, Van Bakel, Fraaije, Jagt & Klompmaker, 2012 (all four in Glaessneropsoidea Schweitzer & Feldmann, 2009) might, in fact (at least for some of them), be true eubrachyurans (Eubrachyura Saint Laurent, 1980). If correct, these assumptions would date the first “true crabs” as Jurassic, contrary to the currently held view that the earliest Eubrachyura (heterotremes) did not appear until the Cretaceous, and suggest that the evolutionary history of brachyurans started much earlier. This was unpredictable, at least for palaeontologists, but not so in view of a molecular estimate of decapod phylogeny that recovered the Majoidea Samouelle, 1819 as the oldest brachyuran lineage, with a divergence from other brachyurans from, at least, the Middle Triassic. The basal majoid family Oregoniidae Garth, 1958, which comprises only three extant genera, has several characters in common with Archaeochiapasidae; these leave little doubt about their close relationships.

DOI:10.3389/fmars.2021.749078
Résumé [+] [-]Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions. However, taxon identification from images is challenging and often relies on morphotypes without considering a taxonomic framework. Taxon identification is particularly challenging in regions where the fauna is poorly known and/or highly diverse. Furthermore, the efficiency of imagery and physical sampling may vary among habitat types. Here, we compared biodiversity metrics (alpha and gamma diversity, composition) based on physical sampling (dredging and trawling) and towed-camera still images (1) along the upper continental slope of Papua New Guinea (sedimented slope with wood-falls, a canyon and cold seeps), and (2) on the outer slopes of the volcanic islands of Mayotte, dominated by hard bottoms. The comparison was done on selected taxa (Pisces, Crustacea, Echinoidea, and Asteroidea), which are good candidates for identification from images. Taxonomic identification ranks obtained for the images varied among these taxa (e.g., family/order for fishes, genus for echinoderms). At these ranks, imagery provided a higher taxonomic richness for hard-bottom and complex habitats, partially explained by the poor performance of trawling on these rough substrates. For the same reason, the gamma diversity of Pisces and Crustacea was also higher from images, but no difference was observed for echinoderms. On soft bottoms, physical sampling provided higher alpha and gamma diversity for fishes and crustaceans, but these differences tended to decrease for crustaceans identified to the species/morphospecies level from images. Physical sampling and imagery were selective against some taxa (e.g., according to size or behavior), therefore providing different facets of biodiversity. In addition, specimens collected at a larger scale facilitated megafauna identification from images. Based on this complementary approach, we propose a robust methodology for image-based faunal identification relying on a taxonomic framework, from collaborative work with taxonomists. An original outcome of this collaborative work is the creation of identification keys dedicated specifically to in situ images and which take into account the state of the taxonomic knowledge for the explored sites.

Harasewych M.G. 1986. The Columbariinae (Gastropoda: Turbinellidae) of the eastern Indian Ocean. Journal of the Malacological Society of Australia 7(3-4): 155-170
Résumé [+] [-]The occurrence of the subfamily Columbariinae in the eastern Indian Ocean is documented for the first time. Of the 5 species recognized, one, Coluzea distephanotis, new combination, has been previously described from the Torres Strait. Additional material suggests that this type locality is erroneous. Four new species, Coluzea aapta, C. icarus, C. liriope and C. gomphos are described. The eastern Indian Ocean species appear to be more closely related to their congeners from off southern and eastern Africa than to those from off New Zealand, suggesting post-Eocene vicariance of at least some elements of the psychrospheric faunas of the Indian and Pacific Oceans.

Mémoires du Muséum national d'Histoire naturelle 180:267-302, ISBN:2-85653-520-3
Résumé [+] [-]The study of many samples collected by MUSORSTOM cruises, deposited in the Muséum national d'Histoire naturelle, as well as the reexamination of types and published specimens reveal that Pasiphaea sivado (Risso, 1816) and the related species, P. propinqua de Man, 1916, P. japonica Omori, 1976, P. marisrubri Iwasaki, 1989 and P. nudipeda Burukovsky, 1993, belong to one group. All are characterized by a terminal spine on the sixth abdominal somite and a branchial reduction. However, P. nudipeda is entirely devoid of arthrobranchia, has unarmed first pereiopods and three pairs of spines on the posterior margin of telson and has to be separated; a new genus Alainopasipheae is proposed for it. The other species mentionned above, except P. marisrubi, bear three arthrobranchiae from the fourth to sixth thoracic somites. P. marisrubri and five new species found in the MUSORSTOM material and belonging in this group have four pleurobranchiae from the fourth to seventh thoracic somites. On the other hand, P. propinqua, P. japonica and P. sivado have one more, but rudimentary, pleurobranchia on the eight somite. A key for all these species is provided.

Résumé [+] [-]The Pasiphaea cristata species group is treated herewith, as the second part of the revision of genus Pasiphaea Savigny, 1816. The group is primarily characterized by presence of a complete gill formula, unarmed posterior margin of the merus of the first pereopod, and unarmed posterior margin of the ischium and basis of the second pereopod. The group comprises twenty two species, four of which are new species from MUSORSTOM material. Pasiphaea nishiei Iwasaki proves to be a junior synonym of P. merriami Schmitt, and P. vereschhaka Burukovsky is probably a junior synonym of P. amplidens Bate. Pasiphaea australis Hanamura has the same pereopodal armatures as this group, but entirely lacks arthrobranchs and is referred to Alainopasiphaea Hayashi. The genus Pasiphaea is redefined by including Phye Wood-Mason as a synonym. A key to the species of P. cristata group is presented. Each species is defined and most species are redescribed and/or refigured.

Résumé [+] [-]During a survey of Taiwanese waters a new species, Pasiphae mclaughlinae n. sp., was discovered. This new species belongs to the P. sivado species group which is characterized by having a reduced branchial formula. The new species can be distinguished from other members of this group by the combination of the following characters: flat dorsal surface of the second to f ifth abdominal somites, unarmed basis and ischium of the second pereopods, and a lower number of meral spines on the first and second pereopods.

Résumé [+] [-]The Pasiphaea alcocki species group is treated herewith, as the third group of the genus Pasiphaea Savigny, 1816. The group is primarily characterized by a deeply concave posterior margin of the telson and the distinctly carinate dorsal margin of the carapace and abdomen. The meri of the first and second pereopods are always armed with many spines, and the ischium and/or basis of the second pereopods are sometimes armed with spines. The group comprises 17 species including two new species both from MUSORSTOM material, Pasiphaea ledoyeri n. sp. and Pasiphaea major n. sp., which are large size species. P. berentsae Kensley, Tranter & Griffin, 1987 is proved to be a junior synonym of P. barnardi Yaldwyn, 1971. P. balssi Burukovsky&Romensky, 1987 is probably a junior synonym of P. rathbunae (Stebbing 1914a). A key to the species of P. alcocki group is presented. Each species is diagnosed and most species are redescribed and/or figured.

Studies on Malacostraca: Lipke Bijdeley Holthuis Memorial Volume:315–331
Résumé [+] [-]Petrolisthes militaris (Heller, 1862) is redescribed on the basis ofmaterial from the Nationaal Natuurhistorisch Museum—Naturalis, Leiden, and the Muséum National d’Histoire Naturelle, Paris. A different morphotype, consistently showing a different distributional and ecological range from that of P. militaris, is here described as P. holthuisi n. sp. Phylogenetic analyses of a dataset based on DNA sequences of a fragment of the mitochondrial COI gene from individuals representing the two forms support the separation of these into two species. While P. militaris has a wide distribution in the Indo-West Pacific including the Red Sea, the new species seems to be restricted to the western side of the Malayan Peninsula through the Malayan Archipelago, eastward to Vanuatu. In addition, Petrolisthes militaris has a broad bathymetric range from the intertidal to 600 m, while P. holthuisi n. sp. is limited to shallow water.

Résumé [+] [-]Several species of palaemonid shrimps are known to act as fish-cleaning symbionts, with cleaning interactions ranging from dedicated (obligate) to facultative. We confirmed five evolutionarily independent origins of fish cleaning symbioses within the family Palaemonidae based on a phylogenetic analysis and the ancestral state reconstruction of 68 species, including 13 fish-cleaners from the genera Ancylomenes, Brachycarpus, Palaemon, Periclimenes, and Urocaridella. We focus in particular on two distantly related lineages of fish cleaning shrimps with allopatric distributions, the Indo-West Pacific Ancylomenes and the western Atlantic monophyletic Ancylomenes/Periclimenes group, which exhibit striking similarities in morphology, colouration and complex behaviour. Specifically, representatives of both lineages are similar in: (1) the general body shape and colour pattern; (2) the utilization of sea anemones as conspicuous cleaning stations; and (3) the use of sideways body swaying to visually promote their bright colour spots in order to attract fish clients. Such morphological, ecological and ethological convergences are apparently due to adaptations to fish cleaning linked to the establishment of similar modes of communication with fish clients in these species.

Résumé [+] [-]Wood falls in the deep sea have recently become the focus of studies showing their importance as nutrients on the deep-sea floor. In such environments, Crustaceans constitute numerically the second-largest group after Mollusks. Many questions have arisen regarding their trophic role therein. A careful examination of the feeding appendages, gut contents, and gut lining of Munidopsis andamanica caught with wood falls revealed this species as a truly original detritivorous species using wood and the biofilm covering it as two main food sources. Comparing individuals from other geographic areas from substrates not reported highlights the galatheid crab as specialist of refractory substrates, especially vegetal remains. M. andamanica also exhibits a resident gut microflora consisting of bacteria and fungi possibly involved in the digestion of wood fragments. The results suggest that Crustaceans could be full-fledged actors in the food chains of sunken-wood ecosystems and that feeding habits of some squat lobsters could be different than scavenging.

Résumé [+] [-]Squat lobsters of the deep-sea genus Munidopsis are among the most regularly reported crustaceans associated with deep-sea wood falls. They are often thought to indirectly use these substrates for preying or scavenging wood-associated molluscs or annelids, albeit the species M. andamanica has been recently highlighted as a xylophagous specialist. In this work, we examined the feeding appendages, gut contents and gut lining of M. nitida, M. bispinoculata and M. pilosa specimens from natural sunken woods and compared them with specimens of the same species having survived and grown on different hard-to-digest substrates (i.e. woods, turtle shells and whale bones) experimentally submerged in the deep South Pacific. In both cases, all three species directly ingest large wood fragments deeply degraded by microorganisms, but M. nitida also feeds on experimentally submerged whale bone and turtle shell fragments. Munidopsis nitida is also the only species to host a resident gut microflora, but the bacterial morphotypes vary according to the ingested substrate. The results suggest that the three species are most probably opportunistic, bacterivorous detritivores and that M. nitida could be at the beginning of an evolutionary process towards xylophagy within the genus Munidopsis.

Huang Y.H. & Shih H.T. 2021. Diversity in the Taiwanese Swimming Crabs (Crustacea: Brachyura: Portunidae) Estimated through DNA Barcodes, with Descriptions of 14 New Records. Zoological Studies: 45
Résumé [+] [-]The swimming crabs (family Portunidae) are distributed worldwide and commonly inhabit estuaries, mangroves, reefs, shallow and the deep sea. Previously, 75 species and 19 genera in this family were known to Taiwan. Our study examined specimens in Taiwanese waters, including the islands, collected between 2016 and 2020 or deposited in museums. Through the cytochrome oxidase subunit I DNA barcode marker and morphological examination, 71 species were identified. The minimum interspecific distances were greater than 4.09%, except in two unresolved groups: Charybdis miles (De Haan, 1835) and Ch. sagamiensis Parisi, 1916, as well as Thranita pelsarti (Montgomery, 1931) and Thr. prymna (Herbst, 1803). In addition, 14 species belonging to nine genera were confirmed as new records to Taiwan, viz. Carupa ohashii Takeda, 1993, Lupocyclus inaequalis (Walker, 1887), Luu. tugelae Barnard, 1950, Lupocycloporus minutus (Shen, 1937), Monomia gladiator (Fabricius, 1798), M. lucida Koch & Ďuriš, 2018, Podophthalmus minabensis Sakai, 1961, Thalamita gatavakensis Nobili, 1906, Tha. spinifera Borradaile, 1902, Thalamitoides quadridens A. Milne-Edwards, 1869, Tho. tridens A. Milne-Edwards, 1869, Thr. cerasma (Wee & Ng, 1995), Thr. coeruleipes (Hombron & Jacquinot, 1846) and Xiphonectes tuberculosus (A. Milne-Edwards, 1861). This study thus raises the total number of Portunidae species in Taiwan to 89.

Résumé [+] [-]A new species of Erebonasteridae, Amphicrossus pacificus, is decribed on the basis of a single female from a depth of 155 m north of New Caledonia in the Grand Passage zone. The new species is closely related to Erebonaster spinulosus Humes and for that reason the latter is transferred to the new genus Amphicrossus. Differences in body ornamentation and armature of maxilla, maxilliped and P4 serve to distinguish Amphicrossus and Erebonaster. Other noticeable discrepancies are found in the structure of the rostrum, the shape of the thoracic epimera and the design of the fifth pair of legs. A peculiar structure, the "sensory area", is shown on the posterior surface of enp-2 P2 in both Amphicrossus species which can be differentiated from each other on the basis of differences in antennulary setation, ornamentation of P1-P4 (exopods, intercoxal sclerites) and length: width ratio of anal somite and P5 exopod. The discovery of A. pacificus in the southern hemisphere considerably extends both the depth range and geographicaJ range of the family.

Résumé [+] [-]The spermatozoa of Homologenus sp., Latreillopsis sp., Homolomannia sibogae and Paromolopsis boasi confirm characteristics of a distinctive homolid spermatozoon previously estabfished for Homola sp., Paromola sp. and Paromola petterdi. Homolid features are (1) moderate anteroposterior depression of the acrosome (ratio of length: width 0.4-0.6) as in lyreidine raninids (0.5), depression being greater in dromiids and dynomenids (both 0.3); (2) the capitate form of the perforatorium, shared with dromiids, dynomenids and lyreidine raninids; (3) the autapomorphic spiked-wheel form of the anterior expansion of the perforatorium; (4) horizontal zonation of the acrosome is possibly a unique synapomorphy of homohds with dromiids and dynomenids, and therefore an autapomorphy of the dromioid-homohd assemblage. In dromiids the posterior zone is proportionately the larger, while in homolids the anterior zone is the larger. The anterior zone is complexly subdivided in dynomenids; (5) the autapomorphic presence of numerous radial arranged extensions of the acrosomal operculum into the perforatorium; (6) presence of nuclear arms, a symplesiomorphy of all investigated crabs, but small or questionably sometimes absent in Dromiidae; (7) absence of microtubules from the nuclear arms, as in dromiids, raninids, higher heterotremes and thoracotremes; (8) transient presence of a posterior median process of the nucleus. The process is not seen in dromiids but occurs in anomurans and lower heterotremes; (91 apical perforation of the operculum, also seen, apparently symplesiomorphically, in dromiids, raninids, and lower heterotreme families; (10) absence of an acrosome ray zone, probably homoplasic with absence in raninids; (11)location of most of the cytoplasm, including tortuous membranes and degenerating mitochondria, below the acrosome,also seen in Lyreidus; (12) presence, in at least some species, of centrioles, unknown in dromiids and raninids and variable in occurrence in heterotremes.

Résumé [+] [-]Features of the spermatozoon of Calocarcinus apicanus which are general for heterotremes and endorse its inclusion in the Heterotremata are: extension of the subacrosomal chamber almost to the anterior apex of the sperm, presence of an acrosome ray zone, and presence of a thickened ring where the capsule surrounds the base of the subacrosomal chamber. A feature shared with ,highern heterotremes is the restriction of cytoplasm to the periacrosomal region, the arms being nuclear only, in contrast with invasion of their chromatin with cytoplasm and microtubules in majids; and loss of a posterior median process, containing chromatin, which is present in majids as in raninids and homolids. The relationship of Calocarcinus with xanthids is unequivocally apported b y (1) presence of a posterior circumperforatorialz one, the xanthid ring; (2) the precise form of the acrosome ray mne which is wide anteriorly and sends a long acrosome zone; (4) division of the operculum complex into a distinct upper zone and a lower, subopercular zone of lesser diameter; and (5)presence of an accessory ring around the in Calocarcinus may indicate origin of thoracotremes from a related xanthoid stock. A difference of Calocarcinus sperm from those of xanthids is the (plesiomorphic) presence of centrioles, also seen in some heterotremes and thoracotremes. No synapomorphies which are not common to other heterotremes are shared between Calocarcinus and trapeziid sperm. nTrapeziid sperm (plesiomorphically?) lack the xanthid ring, the posterior extension of the acrosome ray zone and the irregular margin of the outer acrosome mne of Calocarcinus and xanthids. Apomorphic features of the Calocarcinus africanus sperm include a spiral Configurationn of the contents of the outer acrosome zone (autapomorphy?), as seen in cross-section, and presence of a periopercular rim. A well developed periopercular rim is known elsewhere only in Potamonautes (family Potamidae), but a rudiment occurs in some xanthids (e.g., Etisus). The periopercular rim is probably a true synapomorphy indicative of relationship of potamids to xanthoids (represented by Calocarcinus) which has been postulated elsewhere on morphological grounds.

Résumé [+] [-]The dynomenid spermatozoon, exemplified here by Paradynomene tuberculata, resembles the spermatozoa of the Dromiidae, Homolidae and lyreidine raninoids and differs markedly from those of other crabs (the heterotreme, thoracotremes, raninines and raninoidines) in the depressed, discoidal form of the acrosome and the capitate form of the perforatorium. Four or five apparent dynomenid - dromiid sperm synapomorphies are recognizable. (1) Dynomenids (P. tuberculata) and dromiids differ from homohds and lyreidines in the greater depression of the acrosome (ratio of length to width --- 0.3); (2) the capitate head of the perforatorium is bilaterally prolonged in P. tuberculata as in dromiids though symmetrical in homolids; (3) dynomenid and dromiid sperm lack the - albeit variably developed - posterior median process of the nucleus seen in homolids, anomurans, raninoids and lower heterotremes; (4) P. tuberculata, like dromiids and less distinctly homolids, has an apical protuberance of subopercular material through the opercular perforation, unknown in other crabs, being distinct from the apical button of thoracotreme sperm; (5) a less certain synapomorphy is the anterolateral electron-pale peripheral zone of the acrosome. These synapomorphies endorse a sister-group relationship of dynomenids and dromiids, P. tuberculata sperm differs notably from the sperm of dromiids in the more complex zonation of the acrosome. The perforatorium lacks the radial rays ("spiked wheel") of homolid sperm and does not show the "amoeboid" form seen in lyreidines. Absence of internal corrugations of the perforatorial chamber is a major difference from all examined raninids. Centrioles are only very tentatively identifiable. Nuclear arms are absent in glutaraldehyde fixed spermatozoa of P. tuberculata and have not been observed in the dromiid Petalomera lateralis but are present as three small radial vertices in the dromiid Dromidiopsis edwardsi and in homolids. P. tuberculata resembles Petalomera lateralis in the large size of the sperm nucleus relative to the acrosome compared with D. edwardsi and homolids.

Résumé [+] [-]Parsimony analysis, whether using only spermatozoal characters or spermatozoal and non-spermatozoal characters, suggests that: (i) the Brachyura is a monophyletic taxon relative to the outgroup, three paguroids; (ii) the Podotremata is a monophyletic taxon and the sister-group of the heterotreme thoracotreme assemblage; (iii) within the Podotremata, the Dromiidae appears paraphyletic as its cladeincludes Paradynomene; (iv) the Homolidae is a monophyletic family; (v) the Raninoidea andCyclodorippoidea are sister groups within a monophyletic (unnamed) clade; (vi) Latreillia sp. forms apolytomy with Homolidae + Raninoidea-iCyclodorippoidea; and (vii) within the heterotremethoracotremeassemblage, the Thoracotremata is a monophyletic taxon but the Heterotremata s.strict. Is a paraphyletic grouping. Analyses based on sperm data alone differ from the combined datain not including the Homolidae in the Archaeobrachyura (Homolidae + Raninoidea-Cyclodorippoidea), thus the Dromiidae-Paradynomene + Homolidae + Latreillia form a polytomous clade which is the sister-group of the Raninoidea + Cyclodorippoidea. Spermatozoal data also give majids the most basal position in the Heterotremata whereas for the combined data Neodorippe (a shell carrier) appears the least modified member of the heterotreme-thoracotreme assemblage. These findings are viewed in the perspective of other, notably molecular, studies. Spermatozoal synapomorphies are listed and illustrated.

Résumé [+] [-]Spermatozoal synapomorphies which singly or collectively distinguish Raninoidea are: (1) the presence of single (Ranina, Raninoides) or multiple (Lyreidus) keellike projections of the acrosomal capsule; (2) a very large, weakly electron-opaque peripheral acrosomal zone (Ranina, Raninoides) and an homologous large outer zone in Lyreidus; (3) poor differentiation of the operculum from the capsule (autapomorphy); (4) a very well developed, perforate subopercular zone, of variable forni; (5) presence of unique inward longitudinal projections (septa or corrugations) in the wall of the subacrosomal chamber (autapomoiphy). Shared, presumably synapomorphic characters of Ranina and Rariinoides but not of Lyreidus within the Raninidae, are: (1) branching of some of the subacrosomal septa (unbranched in Lyreidus); (2) the subspheroidal form of the acrosome in Ranina with a 1ength:width ratio (L : W) of 0.76. and, although slightly more depressed, in Raninoides (L : W 0.73), considered apomorphic relative to the more depressed form in Lyreidus (L: W 0.52); (3) single or multiple coiled perforatorial filaments (Ranina, Raninoides) contrasting with a capitate perforatorium with “amoeboid” head in Lyreidus; (4) division of the capsule wall to give one posterior (Kanina) or multiple enclaves, plesiomorphically (?) absent in Lyreidus. Similarities of Lyreidus with other podotremes include the capitate perforatorium, questionably related to the radiate spiked- wheel structure of homolids in which acrosome proportions are similar or less closely to the bilateral capitate perforatorium of dromiids and dynomenids, and basal capsular projections as in the dromiid Stinidrontia (= Petarnalera) lateralis and in cyclodorippoids. No spermatozoal synapomorphies support a sister-group relationship of raninoids and heterotreme-thoracotreme crabs.

Jamieson B.G.M., Guinot D., Tudge C.C. & Richer de forges B. 1997. Ultrastructure of the spermatozoa of Corystes cassivelaunus (Corystidae), Platepistoma nanum (Cancridae) and Cancer pagurus (Cancridae) supports recognition of the Corystoidea (Crustacea, Brachyura, Heterotremata). HELGOLÄNDER MEERESUNTERSUCHUNGEN 51: 83-93
Résumé [+] [-]A combination of characters, not individually unique, possessed by the corystid, Corystes cassivelaunus, and the two cancrids, Platepistoma nanum and Cancer pagums, defines a corystoid-type of spermatozoon: the basally bulbous, anteriorly narrowing perforatorium, the extent of this almost to the plasma membrane through a widely perforate operculum, and the simple inner acrosome zone, lacking an acrosome ray zone. The sperm of the two cancrids are closely similar, that of the corystid differing, for instance, in the less pointed, and less tapered, form of the perforatorium. This relative uniformity of spermatozoal ultrastructure in the cancrid+corystid assemblage so far investigated supports inclusion of the two families in the superfamily Corystoidea by Guinot (1978). The combination of perforation of the operculum and absence of an acrosome ray zone (at least in a clearly recognizable form) are features of the Potamidae which possibly indicate that the latter family, modified for a freshwater existence, is related to the cancrid+corystid assemblage. Some elongation of the centrioles, apparent at least in Corystes, may be a further link with potamids in which they are greatly elongated. The coenospermial spermatophores of cancridoids are a notable difference from the cleistospermia of potamids; but the latter is probably an apomorphic modification for fertilization biology.

Résumé [+] [-]A total of 17 species, in 14 genera of majids have been examined for sperm ultrastructure. The present account describes the sperm of six of these species, in two subfamilies: Pisinae Sphenocarcinus orbicularus and Sphenocarcinus stuckiae and Inachinae-Cyrtomaia furici, Gypacheus hyalinus. Flatymaia rebierei and Macropodia longirostris. M. longirostris has the only eubrachyuran sperm in which the acrosome is known to depart radically from a subspheroidal form. The acrosome is semilunar in shape and is bordered by a very thin layer of cytoplasm and an unusually uniform, narrow band of chromatin. The apical surface of the acrosome is almost flat, though slightly concave, whereas the posterior surface forms a hemisphere, and is almost completely occupied by the thin, centrally perforate, electron dense operculum. The bulk of the acrosome consists of a homogeneous, moderately electron dense outer acrosome zone. This surrounds a small inner acrosome zone internal to which is an ellipsoidal, pale perforatorium capped by a central acrosome zone. Majid sperm are distinguished by a flattened andlor centrally depressed operculum; a further characteristic is that the pointed perforatorium is relatively short and frequently does not reach the operculum. They vary inter alia with regard to presence or absence of a posterior median process and, apparently. Of centrioles and of microtubules in the nuclear arms, and in the number of these ams. Perforation of the operculum, seen in the Pisinae, is not constant in the Inachinae. Spermatozoal ultrastructure offers no certain support for a close relationship of majids with parthenopids or hymenosomatids.

Mémoires du Muséum national d'Histoire naturelle 184:141-283, ISBN:2-85653-526-7
Résumé [+] [-]Balanomorph barnacles of the superfamilies Chionelasmatoidea and Pachylasmatoidea collected by various French deep-sea expeditions in the waters of New Caledonia, Vanuatu, and the Wallis and Futuna Islands are discussed. One sample from the Marianas Islands is also included. Of the 21 species reported herein, 18 are new to science, 2 are recognised as relictual, and 1 represents a northward range extension within the waters of the southwestern Pacific Ocean. In addition 4 new genera and 1 new subfamily are described. An exceptional diversity of species occurs in the subfamilies Pachylasmadnae and Hexelasmadnae of the family Pachylasmatidae. The number of new pachylasmatines described represents 46% of the known species and that of the new hexelasmatines 40%, indicating the richness of these waters. Of the 17 new species described from the waters of New Caledonia, Vanuatu, and the Wallis and Futuna Islands, 14 are considered presently to be endemic to the Vanuatu/New Caledonian region and the remaining 3 occur in a broader area which includes the Futuna and Wallis Islands region. The richest fauna occurs at the Loyalty Islands (15 species), the Norfolk Ridge (11 species) and New Caledonia (11 species). The occurrence of 2 relictual species, the chionelasmaune Chionelasmus darwini and the eolasmatineWaite/aima boucheti, in the waters of the New Caledonian region supports the hypothesis that the southwestern Pacific is a relictual area.

Résumé [+] [-]Les espèces les plus communes de crustacés décapodes et stomatopodes de Nouvelle- Calédonie ont été photographiées en mars 2009 dans 3 stations principales : en Province Sud, aux environs de Nouméa et sur les îlots Rédika et Ka ; en Province Nord, entre la presqu'île de Pindaï et Voh ; et aux îles Loyauté, à Lifou. Au total 19 stations ont été visitées en pêche à pied à basse-mer ou en plongée sous-marine sur des fonds de 1-20 m, de jour et de nuit. Une petite collection de référence a été constituée pour un examen au laboratoire nécessaire à certaines déterminations. Cette récolte est déposée dans les collections du Muséum national d'Histoire naturelle de Paris. Les photographies des auteurs réalisées in situ ou au laboratoire ont été complétées avec celles d’une dizaine de plongeurs photographes ayant accepté de participer à ce projet de recherche. La photothèque ainsi constituée comprend plus de 600 clichés exploitables, correspondant à 176 espèces différentes. Ces photographies sont présentées sur des planches photographiques pour servir d’aide à la détermination aux gestionnaires de l’environnement marin de Nouvelle-Calédonie et aux plongeurs photographes amateurs. Les espèces sont présentées par ordre alphabétique sur des planches regroupées par grands groupes taxonomiques : stomatopodes et langoustes, crevettes, bernard l’ermite, et crabes. Les déterminations provisoires sont indiquées par 'cf.' Parallèlement à cet inventaire photographique, une liste documentée préliminaire des espèces de crustacés stomatopodes et décapodes terrestres et de petits fonds, en excluant les espèces toujours récoltées au-delà de 100 m, est proposée pour la Nouvelle-Calédonie et les archipels voisins (Chesterfield, Entrecasteaux, Loyauté). Cette liste a été compilée en collaboration avec B. Richer de Forges et C. Hoffschir du centre IRD de Nouméa à partir des données de la BD 'Océane', complétées par les nouveaux signalements effectués au cours de ce travail et une recherche bibliographique supplémentaire. Elle comprend 939 espèces pour lesquelles sont indiquées : profondeurs minimale-maximale, au moins une référence bibliographique attestant de sa présence en Nouvelle-Calédonie, la liste des campagnes de prospection concernées et des lieux-dits de récolte.

Résumé [+] [-]The present study describes a new species of Pyrgoma Leach, 1817, a coral associated barnacle attached to Tubastrea, from the south of New Caledonia. Pyrgoma spurtruncata sp. nov. is morphologically close to P. cancellatum Leach, 1818, P. japonica Weltner, 1897 and P. kuri Hoek, 1913 in the absence of extended tergal muscle crests. Pyrgoma cancellatum and P. kuri have a shallow, fully open, medial furrow of the tergal spur, whereas in P. spurtruncata sp. nov. the medial furrow is deeper and closed. Pyrgoma spurtruncata sp. nov. differs from P. japonica Weltner, 1897 in the width of the tergal spur and the length of the rostral tooth of the scutum. Phylogenetic analyses based on two mitochondrial markers, 12S rDNA and COI, confirm a unique, distinct clade of P. spurtruncata sp. nov. among the current available molecular information regarding Pyrgoma species.

Résumé [+] [-]Detailed study of the Monniot collection of copepods belonging to the family Notodelphyidae has revealed an extraordinary diversity of novel taxa. With rare exceptions notodelphyids live in association with ascidians and the Monniot collection was built up over several decades of field collecting and taxonomic research on the ascidian hosts by Drs Claude & Françoise Monniot (MNHN, Paris). This paper describes a total of 178 new species of notodelphyids from ascidian hosts and 37 new genera are established: Bathynotodelphys gen.nov., Pronotodelphys gen. nov., Ooishillgia gen. nov., Nobinerilla gen. nov., Notopygus gen. nov., Chelipygus gen. nov., Sympygus gen. nov., Vaoda gen. nov., Gosbia gen. nov., Pentachaetus gen. nov., Diceratus gen. nov., Prodoroixys gen. nov., Notoixys gen. nov., Borixys gen. nov., Cystixys gen. nov., Ammonixys gen. nov., Ctenixys gen. nov., Ademoixys gen. nov., Gallincola gen. nov., Scoliosoma gen. nov., Contoura gen. nov., Unimeria gen. nov., Mecodelphys gen. nov., Tubipedia gen. nov., Procampodelphys gen. nov., Janius gen. nov., Campodelphys gen. nov., Hamaticoxa gen. nov., Adrodelphys gen. nov., Phyllodelphys gen. nov., Lissodelphys gen. nov., Nodoscarus gen. nov., Diblastus gen. nov., Chilodelphys gen. nov., Scaridelphys gen. nov., Socotradelphys gen. nov., and Aplodelphys gen. nov. Prior to this study the Notodelphyidae comprised exactly 200 valid species classified in 46 genera, a mean species richness of 4.3 species per genus. After the addition of the new taxa described here, the family now comprises 378 species in 83 genera, a mean species richness of 4.6 species per genus. Generic diagnoses are provided for all genera represented in the collection and the availability of a wider range of taxa has allowed certain generic boundaries to be better defined, resulting in transfers of species between genera and the recognition of 16 new combinations. A further 51 existing species are also reported, and brief supplementary notes or full redescriptions are provided as appropriate.

Résumé [+] [-]Two new species of the hitherto monotypic family Intramolgidae are described, both are placed in the type genus Intramolgus Marchenkov & Boxshall, 1995. Intramolgus heardensis sp. nov. was found in association with Polyzoa opuntia Lesson, 1830, and the host of I. atlantis sp. nov. was Styela chaini Monniot C. & Monniot F., 1970. Eleven new species belonging to the family Lichomolgidae are reported. These include four new monotypic genera: Antarctomolgus gen. nov. accommodates A. molgulae gen. et sp. nov. from Molgula pedunculata (Herdman, 1881), Didemnomolgus gen. nov. accommodates D. crenulatus gen. et sp. nov. from Didemnum molle (Herdmann, 1886), Spheromolgus gen. nov. accommodates S. rarus gen. et sp. nov. from Diplosoma simile (Sluiter, 1909), and Alupa gen. nov. accommodates A. geminata gen. et sp. nov. from Leptoclinides madara Tokioka, 1953. The remaining new species are: Debruma deplanata sp. nov. from Ascidia ornata Monniot F. & Monniot C., 2001, Lichomolgidium bipartitum sp. nov. from Pyura stolonifera (Heller, 1878), Lichomolgus papuensis sp. nov. from Rhopalaea circula Monniot F. & Monniot C., 2001, L. brevicaudatus sp. nov. from an unidentified species of Polycarpa Heller, 1877, L. alatus sp. nov. from Synoicum castellatum Kott, 1992, L. lepidotus sp. nov. from Aplidium altarium (Sluiter, 1909), and Lobomolgus foveolatus sp. nov. from Didemnum molle (Herdmann, 1886). In addition, redescriptions are provided for Henicoxiphium redactum Illg & Humes, 1971, Lichomolgidium sardum Kossmann, 1877, Lichomolgus canui Sars, 1917, L. forficula Thorell, 1860, and Zygomolgus dentatus Kim I.H., 2006.

Résumé [+] [-]Additional specimens belonging to the rare crangonid genus Prionocrangon Wood-Mason and Alcock, 1891 collected from recent deep-sea expeditions in the West Pacific enable a revision of this poorly known genus. The four previously described species are all valid. The type species P. ommatosteres Wood-Mason and Alcock, 1891, originally known only from the Andaman Sea, is considered to be also distributed in the Philippines and Indonesia. However, the material previously assigned to "P. ommatosteres'' by de Man ( 1920) and Chace ( 1984) from Indonesia and the Philippines actually represents a new species, P. demani sp. nov., close to P. pectinata Faxon, 1896. Prionocrangon pectinata and P. curvicaulis Yaldwyn, 1960 are still only known by their types. The distribution of P. dofleini Balss, 1913 is now extended from Japan to Taiwan. Two more new species are recognized. Prionocrangon formosa sp. nov. from Taiwan is closely related to P. curvicaulis while P. paucispina sp. nov. from Taiwan and New Caledonia is unique in having very few dorsal carapace spines. The genus Prionocrangon is newly diagnosed and a key to the species is provided. Nevertheless, a damaged specimen from the Sulu Sea could not be satisfactorily assigned to any of the above seven species, suggesting that this genus may have even higher diversity.

Résumé [+] [-]Scalpellids are one of the largest families of Scalpelliformes and reproduce either androdioeciously or dioeciously. Here, we characterized the first mitogenome of a scalpellid barnacle (Arcoscalpellum epeeum), which was 15,593 bp in length with a 71.5% AT content. In comparison with the pollicipedids Capitulum mitella and Pollicipes polymerus, the tRNA genes of A. epeeum were rearranged between ND3 and ND5, between CYTB and ND1, and between 12S rRNA and ND2. On the mitogenomic tree, the Scalpelliformes families Pollicipedidae and Scalpellidae were not monophyletic, which concurs with previous studies.

Résumé [+] [-]Exceptionally preserved specimens yield critical information about the soft-part anatomy and the evolution of organisms through time. We compiled the first global dataset of exceptionally preserved muscles in malacostracans consisting of 47 occurrences, including 18 new records, predominantly preserved in Mesozoic Konservat-Lagerstätten (>70% of occurrences). Early diagenetic mineralization through phosphatization is the dominant process for exceptional preservation of muscles in malacostracans. Over 70% of taxa with muscles preserved are compressed. Rarer, three-dimensionally preserved specimens allow more detailed study of muscles. One example are specimens of the mid-Holocene ghost shrimp Sergio sp. from Panama, showing exquisitely preserved strings of muscle fibers attached to the shell interior, resembling the muscle arrangement of modern ghost shrimps. Other fossil malacostracans, including the oldest known fossil shrimp, also show musculature similar to modern taxa. We hypothesize that this muscle conservatism may be related to the confined space within the malacostracan shell in conjunction with the relatively stable body plan of several clades. We also assembled the first dataset on muscle attachment scars in malacostracans. Unlike muscles, muscle scars are more common. Approximately 24% of 357 of the articles analyzed yielded evidence of muscle scars, but such scars were only recognized for 19% of the 162 taxon occurrences that showed muscle scars. Muscle scars are common from the Late Jurassic onwards, are found primarily in Brachyura and Axiidea, and do not suffer from a Lagerstätten-effect. Rocks with well-preserved specimens should yield an additional wealth of information on the soft part anatomy of malacostracans. Similarly, muscle scars represent an almost untapped, complementary source of information on muscle evolution.

Résumé [+] [-]The portunid crab Ovalipes iridescens (Miers, 1886) is reported for the first time from the marine waters of Taiwan, and is just the second Ovalipes species known from this region. The only previously known Ovalipes species from Taiwan is a commercially-used species, Ovalipes punctatus (De Haan, 1833). The present study provides morphological and distributional data, and discusses the variability of the external morphology. The colour pattern of the body and the shape of the male gonopods of the newly recorded O. iridescens are illustrated.

Résumé [+] [-]A new species of portunid crab from the genus Cycloachelous Ward, 1942 is described from Vietnamese waters. Cycloachelous levigatus sp. nov. is morphologically most similar to C. orbitosinus (Rathbun, 1911), which was originally described from the syntype series collected from Western Pacific area (Cargados Carajos Islands, Amirante Islands, Seychelles) and C. octodentatus (Gordon, 1938) described from one single male from Singapore. There are differences in the sternal segments, third maxilliped, chela, abdomen and male gonopode shapes. The specific status of C. levigatus sp. nov. is also clearly supported by molecular data. Aside from a comparison of this new species with other known congeners, new photographs of syntypes of C. orbitosinus and the holotype of C. octodentatus are also provided.

Komai T. & Chan T.Y. 2003. A new genus and species of pandalid shrimp (Decapoda: Caridea) from the western Pacific. Journal of Crustacean Biology 23(4): 880–889
Résumé [+] [-]A new genus and new species of pandalid shrimp, Calipandahis elachys, is described on the basis of the specimens from Taiwan, Solomon Islands, and New Caledonia in the western Pacific Ocean. Calipandatus new genus resembles Bitias Fransen, 1990, in the lack of an exopod on the third maxilliped, the short rostrum, and the presence of arthrobranchs on the four anterior pereopods. It is distinguished from Bitias by the presence of tegumental scales, the moderately spaced, fixed dorsal teeth on the rostrum proper, the short antennular stylocerite, and the peculiar structures of the mandibular palp and the chela of the second pereopod. The new species also bears similarity to particular species of Plesionika Bate, 1888, although the absence of an exopod on the third maxilliped sets the new species apart from Plesionika.

Résumé [+] [-]A new cratigonid genus and species, Pseudopontophilus serratus n. gen., n. sp., is established from the southwestern Pacific. The new genus is closely related to Pontophilus Leach, 18 17 and Parapontophilus Christoffersen, 1988 in having at least one pair of lateral teeth oil the rostrum and a postorbital suture on the carapace. It is distinguished from both Pontophilus and Parapontophilus in the completely loss of exopod on the First pereopod and the less reduced second pereopod. Considerable variation in the number of median spines oil the carapace, which not appear to be correlated with either size or sex, is found in this new species.

Mémoires du Muséum national d'Histoire naturelle 191:375-610, ISBN:2-85653-557-7
Résumé [+] [-]A review of the species of the caridean genus Glyphocrangon A. Milne-Edwards, 1881 from the Indo-West Pacific Oceans is presented based on rich collections formed during French expeditions to various regions, and supplemented by extensive material deposited in various institutions throughout the world. The genus is divided into two informal groups primarily based on the development of the eye and the presence or absence of arthrobranchs on the first and second pereopods. This study treats species characterized by a well-developed eye and the presence of arthrobranchs on the first and second pereopods (herein called the Glyphocrangon spinicauda species group). A total of 54 species are recognized in the G. spinicauda species group from the Indo-West Pacific region. Of these, the following 28 are new to science: G. albatrossae (Philippines), G. amblytes (Madagascar and South Africa), G. armata (New Caledonia, Vanuatu, Fiji, Wallis and Futuna islands), G. boletifera (Gulf of Aden), G. chacei (Philippines), G. confusa (Indonesia), G. cornuta (New Caledonia), G. crosnieri (Madagascar), G. conodactylus (New Caledonia), G. dimorpha (New Caledonia), G. ferox (Madagascar), G. formosana (Taiwan and East China Sea), G. indonesiensis (Philippines and Indonesia), G. kapala (eastern Australia), G. saintlaurentae (western Indian Ocean), G. major (New Caledonia), G. lineata (Indonesia and northwestern Australia), G. parva (Philippines), G. perplexa (Japan and Taiwan), G. proxima (Philippines and Indonesia), G. punctata (Philippines), G. richeri (Wallis and Futuna islands), G. robusta (Philippines), G. rubricinctuta (Wallis and Futuna islands), G. runcinata (East China Sea), G. similior (Coral Sea), G. speciosa (New Caledonia), and G. tasmanica (Tasman Sea). Glyphocrangon andamanensis Wood-Mason & Alcock, 1891 and G. mabahissae Calman, 1939, which have been considered to be synonymous with G. investigatoris Wood-Mason in Wood-Mason & Alcock, 1891 and G. dentata Barnard, 1926 respectively, are found to be distinct species. Glyphocrangon juxtaculeata Chace, 1984, the holotype of which is a juvenile, is considered to be a junior subjective synonym of G. regalis Bate, 1888. Glyphocrangon joani Allen & Butler, 1994 is treated as a junior synonym of G. fimbriata Komai & Takeuchi, 1994. Plastocrangon Alcock, 1901 is interpreted as a synonym of Glyphocrangon. The new species are fully described and illustrated, and all but three of the previously known species are redescribed and illustrated: G. gilesii and G. smithii being diagnosed on the basis of published information, G. unguiculata Wood-Mason in Wood-Mason & Alcock, 1891 on published information and provisionally identified material from the western Pacific. One obscurely diagnosed species, G. wagini Burukovsky, 1990 from the southeastern Pacific, is also redescribed in order to establish its affinities. Lectotypes are designated for G. acuminata Bate, 1888, G. pugnax de Man, 1918, G. assimilis de Man, 1918, G. sibogae de Man, 1918, and G. megalophthalma de Man, 1918. Identification key, separated by sex, is provided. This study reveals that most Glyphocrangon species have restricted geographical ranges, with only G. caecescens occurring in both the western Pacific and Indian oceans. The geographic and bathymetric distributions of the treated species are summarized.

Résumé [+] [-]A new genus, Globospongicola, is established for two new species of deep-water spongicolid shrimps, G. nudibranchus n. sp. from Indonesia and G. spinulatus n. sp. from Vanuatu and New Caledonia. The new genus is distinctive in having simple gills completely lacking lamellae or filaments, instead of typical trichobranchiate gills in all other species in the family. Furthermore, the reduced armament on the body and third pereopod separates the new genus from Microprosthema, Paraspongicola, and Spongicola; the well-developed exopod of the third maxilliped distinguishes the new genus from Spongicola, Spongicoloides and Spongiocaris. The two new species can be distinguished from one another by the shape and armature of the rostrum, the spination of the carapace, the shape of the sixth abdominal somite, the shape of the antennal scale, and the armament of the third pereopods and pleopods of male.

Résumé [+] [-]The crangonid genus Lissosabinea Christoffersen, 1988 was established to accommodate two rare deep-water species: Sabinea indica De Man, 1918 and S. tridentata Pequegnat, 1970 (type species). A study of collections made by French expeditions to the western Pacific, supplemented by material from other sources (including types of both known species), has led to a review of the genus. This Study shows that the hypothesis placing Lissosabinea as a sister group of a clade containing three genera: Vercoia, Prionocrangon and Paracrangon, was derived from an insufficient character analysis. Lissosabinea appears most closely related to Sabinea, as suggested by the original generic assignment of the two known species. Lissosabinea maintains full generic status, as the species referred to the genus are clearly differentiated from the three species assigned to Sabinea by a number of morphological characters. Three new species of Lissosabinea are described: L. armata n. sp. from New Caledonia; L. ecarina n. sp. from the Philippines and Indonesia, and L. unispinosa n. sp. from New Caledonia and Tonga. The two known species are redescribed, and L. indica is newly recorded from New Caledonia. The bathymetric and geographic ranges of the species are briefly discussed. A key to the identification of the species of the genus is presented.

Résumé [+] [-]A review of the species of the Glyphocrangon caeca Wood-Mason & Alcock, 1891 group is presented based on samples obtained during French expeditions to the southwestern Pacific and western Indian Ocean, and supplemented with materials deposited in various museums and institutions in the world. Eight species are now recognized in this species group. The two previously described species, G. caeca from the Bay of Bengal and G. cerea Alcock & Anderson, 1894 from the Laccadive Sea, are rediagnosed based on literature, as types or supplemental topotypic specimens of these two species have not been available for study. Six new species are described: G. brevis n. sp. from Madagascar, G. demani n. sp. from Indonesia, G. humilis n. sp. from Japan and Taiwan, G. musorstomia n. sp. from Wallis and Futuna Islands, Vanuatu, Fiji and Chesterfield Islands, G. parviocullus n. sp. from New Caledonia, and G. rudis n. sp. from the Solomon Islands. Species of this group occur exclusively in the Indo-West Pacific. The horizontal and bathymetric distributions of the species are briefly summarized. The available data suggests that species of the group are highly localized.

Résumé [+] [-]A new species of the deep-water shrimp genus Glyphocrangon A. Milne-Edwards, 188 1, G. arduus n. sp., is described from the Austral Islands, French Polynesia. It is the first representative of Glyphocrangonidae known from French Polynesia. The closest morphological affinities of G. arduus n. sp. are with G. speciosa Komai, 2004 from New Caledonia and G. ferox Komai, 2004 from Madagascar. The new species is readily distinguished from G. speciosa by the weak armament of, the posterior third carina on the carapace, different shape of the intercarinal tubercles on the carapace and pleon, and the living coloration. From G. ferox, G. arduus n. sp. is separable by the presence of an acute anterior tooth of the posterior fourth carina on the carapace, sharp intercarinal tubercles on the branchial region and the smaller corneas.

Résumé [+] [-]A review of species of the genus Parapontophilus Christoffersen, 1988 (Decapoda, Caridea, Crangonidae) from the world oceans is presented. This Study is based on the large collection obtained during French expeditions in the eastern Atlantic, western Indian, and tropical western and southern Pacific oceans, and on additional material from various museums and institutions in the world. Eighteen species, including ten new species, are divided in two informal species groups, P. gracilis (Smith, 1882) group and P modumanuensis (Rathbun, 1906) group. The first group contains I I species: P. gracilis (type species of the genus), P abyssi (Smith, 1884), P. junceus (Bate, 1888), P. profundus (Bate, 1888), P occidentalis (Faxon, 1893), P talismani (Crosnier & Forest, 1973), P cornutus n. sp., P cyrton n. sp., P difficilis n. sp., P. geminus n. sp. and P. longirostris n. sp. The second group contains seven species: P. modumanuensis (Rathbun, 1906), P. demani (Chace, 1984), P caledonicus n. sp., P. juxta n. sp., P. psyllus n. sp., P. sibogae n. sp. and P. stenorhinus in. sp. Six taxa originally described as full species by their authors and occasionally treated as subspecies, viz. P. gracilis, P abyssi, P. junceus, P. profundus, P occidentalis, and P talismani, are here maintained as full species because of the existence of morphological differences and of the partial overlap of geographical or bathymetrical ranges. All species are diagnosed or rediagnosed, and illustrated. Synonymies of Pontophilus challengeri Ortmann, 1893 with Parapontophilus abyssi and of Pontophilus occidentalis var. indica de Man, 1918 with Parapontophilus junceus were con firmed. A key to aid in the identification of all Parapontophilus species is given, although it should be used with caution because of intraspecific variations exhibited by many of the species. Bathymetrical and geographical distributions of species are also summarized. All but P. sibogae n. sp. are exclusively found at more than 200 in depth, and particularly three species, P. abyssi, P occidentalis, and P talismani, occur at abyssal depths exceeding 3000 m. Parapontophilus sibogae inhabits shallow water, recorded at depth of I I m in the type locality. Two species, P gracilis and P talismani, appear restricted to the Atlantic Ocean, although widely distributed there. Three species, P abyssi, P longirostris n. sp., and P. juxta n. sp. occur in the Indian Ocean; P abyssi is also widely distributed in the Atlantic and P longirostris extends to the central Pacific. Parapontophilus occidentalis appears restricted to the eastern Pacific. Other species are distributed in the range of the western Pacific to French Polynesia.

Résumé [+] [-]Two new species of the caridean shrimp family Pandalidae were discovered from the recent deep-sea MAINBAZA cruise in the Mozambique Channel. Pandalina spinicauda n. sp. is unique in the genus by having much more numerous dorsolateral spines on the telson. Plesionika neon n. sp. belongs to the "Plesionika rostricrescentis (Bate, 1888)" group that bears distinct basal rostral crest and with elaborate colour patterns, but has the shortest stylocerite and a very different coloration. The rare hippolytid shrimp Leontocaris bulga Taylor & Poore, 1998 was also collected by the MAINBAZA cruise. Leontocaris bulga has only been known before from a damaged specimen lacking abdomen and collected off Tasmania, and therefore, the Mozambique specimen is described and illustrated in detail.

Résumé [+] [-]The bathypelagic shrimp genus Pasiphaea Savigny, 1816 (Caridea: Pasiphaeidae) has been previously known from Taiwan from only three species. However, recent deep-sea surveys around the island have collected numerous specimens comprising ten species, of which four are new to science: P. aeons n. sp., P alcocki (Wood-Mason and Alcock, 1891), P exilimanus n. sp., P. falx n. sp., P japonica Omori, 1976, P. mclaughlinae Hayashi, 2006, P levicarinata Hanamura, 1994, P orientalis Schmitt, 1931, P. sirenkoi Burukovsky, 1987 and P. taiwanica n. sp. The four new species are fully described and illustrated, and compared with allied congeners. Pasiphaea orientalis is redescribed, as this species is endemic to Taiwan and its original description is inadequate. Amongst the three new records of Taiwan, P. levicarinata is also recorded for the first time from the northwestern Pacific.

Résumé [+] [-]Collections made during recent French expeditions off the Mozambique Channel in the western Indian Ocean (MAINBAZA, MIRIKY) and off Papua New Guinea in the southwestern Pacific (BIOPAPUA) yielded a total of 14 species of the deep-water shrimp genus Glyphocrangon A. Milne-Edwards, 1881, including one new to science: G. amblytes Komai, 2004, G. assimilis De Man, 1918, G. brevis Komai, 2006, G. confusa Komai, 2004, G. crosnieri Komai, 2004, G. dentata Barnard, 1926, G. faxoni De Man, 1918, G. indonesiensis Komai, 2004, G. lowryi Kensley, Tranter & Griffin, 1987, G. proxima Komai, 2004, G. pugnax De Man, 1918, G. pulchra n. sp., G. rudis Komai, 2006, and G. speciosa Komai, 2004. Glyphocrangon pulchra n. sp. belongs to the “G. regalis Bate, 1888” species-complex, and differentiating characters between the new species and closely related allies are discussed. The geographical range of G. indonesiensis is greatly extended from the southwestern Pacific to the western Indian Ocean, the identification being supported by both morphological and molecular data. Slight range extensions are also reported for G. lowryi and G. speciosa.

Résumé [+] [-]Two new species of the crangonid shrimp genus Metacrangon Zarenkov, 1965, are described and illustrated on the basis of materials collected from the Okinawa Trough, Ryukyu Islands, southern Japan, during diving operations of remotely operated vehicles (ROVs): M. ryukyu n. sp. from off Iheya Island, at depth of 986 m; and Metacrangon kaiko n. sp. from NE of Yonaguni Island, at depth of 2205 m. The two new species resemble members of the M. munita (Dana, 1852) species group, but are both characteristic in having setose dactyli on pereopods 4 and 5. Some minor differences in morphology and genetic analysis using partial sequences of the barcoding mitochondrial COI gene support the recognition of the two new species. Holotypes of the two new species were collected from hydrothermally influenced areas, representing a previously unknown habitat for species of Metacrangon.

Résumé [+] [-]A collection of the caridean shrimp genus Glyphocrangon A. Milne-Edwards, 1881 (Glyphocrangonidae), made during the South Java Deep-Sea Biodiversity Expedition 2018 (SJADES 2018), is comprised of six species, including one new to science: G. hakuhoae Takeda & Hanamura, 1994, G. indonesiensis Komai, 2004b, G. juxtaculeata Chace, 1984, G. proxima Komai, 2004b, G. serratirostris, new species, and G. sibogae de Man, 1918. Glyphocrangon juxtaculeata, which was originally described on the basis of a single juvenile holotype and previously placed in the synonymy of G. regalis Spence Bate, 1888, is herein reinstated as a valid species on the basis of examination of a newly collected female specimen. Glyphocrangon serratirostris, new species, belongs to the “G. regalis” species complex, but is quite distinctive in having four or more lateral spines on each side of the rostrum. Genetic analyses using partial segments of the mitochondrial COI gene also supports the recognition of the new species.

Résumé [+] [-]A review of species of the crangonid genus Metacrangon Zarenkov, 1965 (Decapoda: Caridea) from the Northwest and tropical Southwest Pacific Ocean is presented. Twenty-one species, including seven new to science, are recognized: M. asiaticus (Kobjakova, 1955) from the Kuril Islands and Komandor Islands; M. bythos n. sp. from Japan; M. clevai n. sp. from the Solomon Islands and Vanuatu; M. cornuta Komai & Komatsu, 2009 from Japan; M. holthuisi Komai, 2010 from Japan; M. karubar n. sp. from Indonesia to Solomon Islands; M. laevis (Yokoya, 1933) from northern Japan and the Russian Far East; M. longirostris (Yokoya, 1933) from Japan; M. miyakei Kim, 2005 from Japan; M. monodon (Birshtein & Vinogradov, 1951) from the North Kuril Islands; M. nipponensis (Yokoya, 1933) from Japan; M. obliqua n. sp. from Japan; M. ochotensis (Kobjakova, 1955) from the South Kuril Islands; M. proxima Kim, 2005 from Japan; M. punctata n. sp. from Indonesia, Solomon Islands and New Caledonia; M. robusta (Kobjakova, 1935) from the Sea of Japan and the Sea of Okhotsk; M. similis Komai, 1997 from Japan; M. sinensis Fujino & Miyake, 1970 from the northern part of the East China Sea; M. trigonorostris (Yokoya, 1933) from Japan; M. tropis n. sp. from Japan; and M. tsugaruensis n. sp. from Japan. These species are classified into two informal species groups. The new species are fully described and illustrated. Some previously known species, for which detailed descriptions along modern standards are deemed necessary, are redescribed. Metacrangon asiaticus is elevated from a subspecies of M. variabilis to full species status. A key to aid in the identification of the western Pacific species is provided. Bathymetrical and geographical distributions of the treated species are summarized. It is strongly suggested that each species is highly localized. The species richness is highest in waters around the Japanese Archipelago (17 of the 41 known species occur in the areas).

Kou Q., Xu P., Poore G.C.B., Li X. & Wang C. 2020. A New Species of the Deep-Sea Sponge-Associated Genus Eiconaxius (Crustacea: Decapoda: Axiidae), With New Insights Into the Distribution, Speciation, and Mitogenomic Phylogeny of Axiidean Shrimps. Frontiers in Marine Science 7: 469. DOI:10.3389/fmars.2020.00469
Résumé [+] [-]Eiconaxius Bate, 1888 is a genus of axiid shrimps exclusively associated with deepsea hexactinellid sponges. Due to its special morphology and habitat, Eiconaxius is taxonomically and ecologically controversial. Based on material recently collected from seamounts in the northwestern Pacific, a new species of Eiconaxius is described. Intraspecific morphological and genetic variation and host specificity were evaluated. The complete mitochondrial genome of the new species was sequenced to explore the systematic status of Eiconaxius and some other axiidean taxa. Our analyses showed that differentiation of the new species occurs both allopatrically and sympatrically, probably resulting from the interaction of geographical isolation and deep water current movement, rather than from adaptation to different hosts. In addition, species of Eiconaxius are suggested to have wider ranges of distribution and host than expected. The reconstructed mitogenomic phylogeny supported merging Eiconaxius into Axiidae, and recognized most axiidean families, except that Strahlaxiidae was suggested to be paraphyletic. However, more comprehensive taxon sampling is still needed to resolve the explicit internal relationships among Axiidea.

Résumé [+] [-]A new genus and species of axiid shrimp, Carolinaxius kexuae gen. et sp. nov. is described and illustrated based on a single specimen collected from an unnamed seamount in the Caroline Ridge, Northwest Pacific. Although both chelipeds are missing, the specimen can be distinguished from other axiid genera by a combination of characteristics: narrowly triangular rostrum; median carina and lateral gastric carina each with one prominent tooth; submedian gastric carinae converging posteriorly, with teeth; cornea weakly pigmented, eyestalk with acute distomesial tooth on dorsal surface; male pleopod 1 two-articled; pleopod 2 with appendix interna and appendix masculina; pleopods 3–5 with appendix interna. The molecular phylogeny suggests the new genus is most closely related to another recently described genus living inside hexactinellid sponges on seamounts in the Indian Ocean, Montanaxius Dworschak, 2016. However, it differs from Montanaxius in the shape of the rostrum, the arrangement of teeth on the carapace, and the shape of the eyestalk. Besides, the significant molecular differences support the two belonging to different genera.

Résumé [+] [-]The evolutionary relationships of the brachyuran crab superfamily Eriphioidea, commonly known as stone or rubble crabs, are examined. Analysis of three mitochondrial (12S, 16S and COI) and two nuclear loci (18S and Histone 3) was carried out for 51 taxa representing the Carpilioidea, Dairoidea, Eriphioidea, Goneplacoidea, Parthenopoidea, Pilumnoidea, Portunoidea, Pseudozioidea and Xanthoidea. Phylogenetic analyses of molecular data used three methods of inference that recovered similar topologies with minor differences. Maximum parsimony analysis of 20 morphological characters taken from first zoeas of 11 species yielded two equally parsimonious trees and generally supported the molecular analyses. None of the analyses recovered Eriphioidea as monophyletic, and each of the eriphioid families represented by two or more taxa was shown to be polyphyletic in both molecular and larval analyses. This study indicates that the present classification based on adult morphology is incongruent with phylogenetic relationships and that the diagnostic characters the result of convergence (particularly in feeding morphology) rather than shared ancestry.

Xanthidae MacLeay, 1838 (Decapoda: Brachyura: Xanthoidea) systematics: A multi-gene approach with support from adult and zoeal morphology. Zoologischer Anzeiger - A Journal of Comparative Zoology 250(4): 407-448. DOI:10.1016/j.jcz.2011.07.002
Résumé [+] [-]Currently, 13 subfamilies are recognised in the brachyuran family Xanthidae: Actaeinae, Antrocarcininae, Chlorodiellinae, Cymoinae, Etisinae, Euxanthinae, Kraussiinae, Liomerinae, Polydectinae, Speocarcininae, Xanthinae, Zalasiinae and Zosiminae. This classification has been based on shared adult features like a transversely ovate carapace, well defined dorsal carapace regions, usually with lateral dentition, stout chelipeds and relatively short ambulatory legs. Such characters are now considered to be convergent. Consequently a number of higher xanthid taxa may be artifical and not monophyletic. A broad sample of 147 xanthid species representing 75 out of 124 genera from all 13 xanthid subfamilies were sampled in a multi-gene analysis. Four markers (three mitochondria] and one nuclear) were used and yielded a tree with ca. 30 xanthid clades. Monophyletic support was demonstrated for the Antrocarcininae (although substantially redefined), Cymoinae, and Polydectinae. Almost every other subfamily was para- or polyphyletic. Furthermore, the two other families of the Xanthoidea, Pseudorhombilidae and Panopeidae, were found nested within the Xanthidae. The molecular results were consistent with phylogenetic relationships implied by a suite of novel and/or neglected "ventral" adult characters including sternal characters, position of genital openings and morphology of the first zoea, instead of "dorsal" characters traditionally used to infer xanthid relationships.

Résumé [+] [-]The deep-water epialtid spider crab (superfamily Majoidea) material collected from recent French expeditions to Papua New Guinea (BIOPAPUA 2010, PAPUA NIUGINI 2012, MADEEP 2014, and KAVIENG 2014) was studied. In addition to several new records for the country, five new species of Oxypleurodon Miers, 1885, Rochinia A. Milne-Edwards, 1875, and Tunepugettia Ng, Komai & Sato, 2017, are described. The taxonomy of Tunepugettia is reappraised, and a new genus, Crocydocinus n. gen., is established, characterised by its smooth ambulatory legs and a distinct male first gonopod structure. Four species from the Bay of Bengal, Sumatra, and Réunion Island, currently placed in Rochinia and Tunepugettia are transferred to Crocydocinus n. gen. and four new species from Papua New Guinea, Philippines, and Vanuatu are described. A new genus, Neophrys n. gen., with one new species from Papua New Guinea, is established, and is characterised by the supraorbital eave being fused with the carapace and the poorly developed pre-orbital angle.

Résumé [+] [-]The single most species-rich genus in the majoid family Epialtidae MacLeay, 1838, is Rochinia A. Milne-Edwards, 1875. Ng et al. (2008) listed 34 species and since then the number of species has continued to grow, especially in the Indo-West Pacific region (see Takeda, 2001; Takeda & Komatsu, 2005; Ng & Richer de Forges, 2007; Richer de Forges & Poore, 2008; Takeda, 2009; McLay, 2009; Ng & Richer de Forges, 2013; Richer de Forges & Ng, 2013; Takeda & Marumura, 2014; Lee et al., 2017; Lee et al., 2019). The systematic problems with the genus are well known; Rochinia, as defined by Griffin & Tranter (1986a) was too broad and clearly polyphyletic. Rochinia sensu Griffin & Tranter (1986a) includes four synonyms: Sphenocarcinus A. Milne-Edwards, 1875, Scyramathia A. Milne-Edwards, 1880, Anamathia Smith, 1885, and Oxypleurodon Miers, 1885. Griffin & Tranter (1986a) also transferred three species that were described under Hyastenus White, 1847, and Pugettia Dana, 1851, to Rochinia. Goniopugettia Sakai, 1986, a genus overlooked by Griffin & Tranter (1986a), included Rochinia sagamiensis (Gordon, 1930), and was recognised by Ng et al.

Résumé [+] [-]The generic positions of the 29 Indo-West Pacific species currently placed in Rochinia A. Milne-Edwards, 1875, sensu lato, are addressed, in an attempt to establish a more phylogenetically coherent classification for these spider crabs. Twenty-five Indo-West Pacific species are referred to a redefined Samadinia Ng & Richer de Forges, 2013. Three species are transferred to Laubierinia Richer de Forges & Ng, 2009, Pugettia Dana, 1851, and Oxypleurodon Miers, 1885, respectively. Rochinia kagoshimensis (Rathbun, 1932) and a new species from the South China Sea are assigned to a new genus. The generic status of four Atlantic species of Rochinia is also discussed.

Résumé [+] [-]Parapagurid hermit crabs are reported for the first time from French Polynesia, based on a collection obtained during a deep-water trapping survey by the French government's Service Mixte de Contrôle Biologique des Armées. The collection contains nine species of the genus Sympagurus Smith, 1883, four of which are new, and one of Slrobopagurus Lemaitre, 1989. The material of the previously described species of Sympagurus found in French Polynesia is compared with types and supplemental specimens from other IndoPacific regions, and the species diagnosed in light of a recent re-evaluation of diagnostic characters in this genus. Based on examination of representative material of ail Sympagurus species from the world oceans, three informai groups are proposed for the species. Group 1, including nine species, is defined by the presence of a slender, curved epistomial spine; Group 2, including ten species, is defined by the presence of a vestigial pleurobranch on each side of the last thoracic somite; and a heterogenous Group 3, for the remaining 14 species and three subspecies, all of which lack a curved epistomial spine and vestigial pleurobranch on the last thoracic somite. A list of all known species of Sympagurus is presented, along with their geographic and bathymetric distributions.

Résumé [+] [-]The examination of all available material of hermit crabs of the genus Xylopagurus A. Milne Edwards revealed the existence of two new species previously confounded with X. rectus A. Milne Edwards. As a result, the genus now contains five species, four of which are known only from the Caribbean Sea, and one of which is from the tropical eastern Pacific. A critical review of all species of Xylopagurus, and a discussion of unusual or unique features, are presented. The two new species, X. anthonii and X. tenuis, are described. A redescription of the type species of the genus, Xylopagurus rectus A. Milne Edwards, sensu stricto, is included, as well as diagnoses of X. cancellarius Walton and X. tayrona Lemaitre and Campos. A key for the identification of the species is presented. With the exception of the recently described X. tayrona, all species are fully illustrated, and complete synonymies are presented.

Mémoires du Muséum national d'Histoire naturelle 172:573-596, ISBN:2-85653-506-2
Résumé [+] [-]During the French-Indonesian KARUBAR campaign, ten species and a megalopal stage of deep-water hermit crabs of the family Parapaguridae, were collected. Two of the species found in the collection are undescribed, Oncopagurus glebosus sp. nov., and Paragiopagurus insolitus sp. nov., and are characterized by several unusual or unique characters. One previously described species, Oncopagurus orientalis (de Saint Laurent, 1972), was found to be insufficiently defined. These three species are described or diagnosed, and illustrated. Another species, Parapagurus latimanus Henderson, 1888, is reported for the first time from Indonesia. Two megalopal stage specimens of a parapagurid species cannot be assigned with certainty based on current knowledge, to any species; they are also illustrated and discussed. A list of all 15 parapagurid species currently known from Indonesian waters is presented, including references where diagnoses and illustrations can be found.

Résumé [+] [-]A review of the deep-water hermit crab species of the genus Parapagurus Smith, 1879 from the Indian and Pacific Oceans is presented based on abundant samples obtained during French expeditions to the New Caledonia region, and supplemented with extensive material deposited in various major museums and institutions throughout the world. A total of 14 species were found to occur in the Indian and Pacific Oceans. Of these seven are new, P. richeri sp. nov., P. furici sp. nov., P. stenorhinus sp. nov., P. saintlaurentae sp. nov., P. janetae sp. nov., P. foraminosus sp. nov., and P. woljfi sp. nov.; and three, P. abyssorum (Filhol, 1885), P. bouvieri Stebbing, 1910, and P. andreui Macpherson, 1984, include parts of the Atlantic Ocean in their distribution. The new species are fully described and illustrated; all previously known species are diagnosed or in the case of one obscurely defined species, P. holihuisi Lemaitre, 1989, redescribed. Information on morphological variations is included for the most abundant species, and a key to aid in the identification of all 14 species is given. Of the seven new species, P. richeri sp. nov. and P. furici sp. nov., were found in the New Caledonia region but are also distributed elsewhere in the Indo-Pacific; P. saintlaurentae sp. nov. and P. stenorhinus sp. nov., have been found exclusively in the Indian Ocean; and P. janetae sp. nov., P. foraminosus sp. nov., and P. wolffi sp. nov., exclusively in the eastern Pacific. As result of this study, the genus now contains 17 species, of which P. pilosimanus Smith, 1879, P. nudus (A. Milne-Edwards, 1891), and P. alaminos Lemaitre, 1986, are so far known only from the Atlantic Ocean. The bathymétrie distribution of all species in the genus is summarized.

Résumé [+] [-]A new deep-water hermit crab species, Paragiopagurus fasciatus, is described from the Austral Islands, French Polynesia. This new species has a distinct colour pattern consisting of red stripes on the shield and ambulatory legs, and is also distinguished by having short antennal peduncles, strongly armed carpus of the left cheliped, and in females, laterally armed telson. This new species is the fourth of the genus, and the twelfth of the family, recorded from French Polynesia. The closest morphological affinities of P. fasciatus n. sp. are with P. bougainvillei (Lemaitre, 1994) and P. wallisi (Lemaitre, 1994), two species also known so far exclusively from French Polynesia. A taxonomically updated list of species from French Polynesia is presented.

Résumé [+] [-]Species of the parapagurid genus Strobopagurus Lemaitre, 1989 are reviewed based primarily on abundant specimens obtained during French campaigns across the Indo-Pacific region. A new species, S. breviacus, is described. The genus contains two other species, S. gracilipes (A. Milne-Edwards, 1891), the type of the genus, and S. sibogae (de Saint Laurent, 1972). One taxon, Parapagurus kilburni Kensley, 1973, originally described from off eastern Africa, has been found to be a junior synonym of S. sibogae. An updated diagnosis of the genus, and diagnoses and comparative illustrations of all three species, are presented together with a key to aid in their identification. Information on live coloration is provided for S. gracilipes and S. sibogae; live coloration of S. breviacus is not known.

Résumé [+] [-]A review of species of the genus Sympagurus Smith, 1883 (sensu Lemaitre) from the world oceans is presented. The study is based on the rich collections obtained during French campaigns in the Pacific and Indian Oceans, and on additional material in various museums and research institutions throughout the world. The 17 species recognised in this genus occur most frequently between 500 and 1000 m depth, and range from 80 to 2537 m. Some live in striking symbiosis with anthozoan or zoanthid coelenterates that can produce pseudo-shells. Three new species, S. aurantium, S. chani and S. symmetricus, are fully described and illustrated here. Sympagurus rectichela (Zarenkov 1990), a taxon originally described in Parapagurus Smith, 1879, has been found to be a junior synonym of S. dofleini (Balss, 1912); and S. papposus Lemaitre, 1996 is a junior synonym of S. burkenroadi Thompson, 1943. All previously known Sympagurus species are diagnosed or redescribed and illustrated, and data on habitat, symbiotic associations, and coloration are provided. A key to aid in the identification of all Sympagurus species is presented, and their bathymetric and geographic distributions are summarised. The geographic distribution of 14 species (82.3%) includes the Pacific Ocean, 9 (52.9.%) the Indian Ocean, and 3 (1.8%) the Atlantic Ocean. New Caledonia and adjacent islands have the highest number of Sympagurus species in the world, with 12 species known to occur there.

Résumé [+] [-]Two new parapagurid species with subconical corneas, Oncopagurus conicus n. sp. and Paragiopagurus schnauzer n. sp., are described based on collections by French expeditions to New Caledonia, the Philippines and Solomon Islands, in the western Pacific. These represent the 16th and 18th documented species of Oncopagurus Lemaitre, 1996 and Paragiopagurus Lemaitre, 1996, respectively. Two other parapagurids are known to have subconical corneas, Sympagurus acinops Lemaitre, 1989, and Oncopagurus minutus (Henderson, 1896). Also reported are specimens of two rare and morphologically unique parapagurids, Typhlopagurus foresti de Saint Laurent, 1972 and Bivalvopagurus sinensis (de Saint Laurent, 1972), and represent geographical and bathymetric range extensions for both species. The diagnoses of the monotypic genera Typhlopagurus and Bivalvopagurus are to be modified due to new data on morphology and biology. The former genus was given to include T.foresti, wrongly assumed to lack cornea, thus presumed blind; and the latter for B. sinensis, prematurely assumed to exclusively use bivalve shells as housing.

Résumé [+] [-]Phylogenetic relationships within the "symmetrical" hermit crab family Pylochelidae were analyzed for 41 of the 45 species and subspecies currently considered valid. In the analyses, 78 morphological characters comprised the data matrix and the outgroup consisted of Thalassina anomala, a member of the Thalassinidae, and Munida quadrispina, a member of the Galatheidae. A poorly resolved strict consensus tree was obtained from a heuristic parsimony analysis of unweighted and unordered characters, which showed the family Pylochelidae and the subfamilies Pylochelinae and Pomatochelinae to be monophyletic taxa - the latter two groups had the highest Bremer support values. Additionally, while the subgenus Pylocheles (Pylocheles) was strongly supported, the subgenera Xylocheles, and Bathycheles were not. More fully resolved trees were obtained when using implied weighting, which recognized the monotypic subfamilies Parapylochelinae, Cancellochelinae and Mixtopagurinae. The subfamily Trizochelinae was found to have four distinct clades and several ambiguously placed taxa.

The genus Paragiopagurus Lemaitre, 1996 (Crustacea, Decapoda, Anomura, Paguroidea, Parapaguridae): A worldwide review and summary, with descriptions of five new species, in Ahyong S.T., Chan T.Y., Corbari L. & Ng P.K.(Eds), Tropical Deep-Sea Benthos 27. Mémoires du Muséum national d'Histoire naturelle 204:311-421, ISBN:978-2-85653-692-6
Résumé [+] [-]A review of the deep-water hermit crab species of the genus Paragiopagurus Lemaitre, 1996 from the world oceans is presented. The core specimen base for this study has come primarily from the abundant collections of species of this genus obtained during French campaigns over the last four decades, and complemented with numerous specimens from many other deep-sea expeditions and deposited in various museum holdings around the world. Paragiopagurus is one of the most speciose genus among the Parapaguridae Smith, 1882, although it is considered a phylogenetically heterogeneous assemblage and does not appear to have an apomorphy of its own. Bathymetrically, the species range in depth from 36 to 2034 m, although they occur most frequently between 200 and 1000 m. The species utilize as housing, gastropod shells (or rarely scaphopod shells, siliceous sponges, or hollow pieces of wood) that may or may not be colonized by actinians or zoanthids. In this review, 24 species are recognized, of which five are new, P. laperousei n. sp., P. orthotenes n. sp., P. oxychelos n. sp., P. trilineatus n. sp., and P. umbonatus n. sp. The new species are fully described and illustrated. All previously known species of the genus are diagnosed or redescribed, and previously published illustrations of important taxonomic characters assembled and complemented, when useful, with new illustrations. The treatment of each species includes a full synonymy, materials examined (type and non-types), colouration, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Colour photographs are included for 14 of the species. Parapagurus curvispina de Saint Laurent, 1974, a species tentatively moved after its description to Sympagurus Smith, 1883 and then to Paragiopagurus, is herein transferred with certainty to Oncopagurus Lemaitre, 1996. Parapagurus spinimanus Balss, 1911, a species that had been incorrectly placed in Paragiopagurus, is herein moved to Sympagurus. Parapagurus sculptochela Zarenkov, 1990, a taxon previously considered a junior synonym of Paragiopagurus boletifer (de Saint Laurent, 1972), is herein resurrected as a valid species of Paragiopagurus. The bathymetric and geographic distributions of Paragiopagurus species are summarized and briefly discussed, including a summary table, graph, and map with generalized distribution patterns.

Lemaitre R. 2014. A worldwide taxonomic and distributional synthesis of the genus Oncopagurus Lemaitre, 1996 (Crustacea: Decapoda: Anomura: Parapaguridae), with descriptions of nine new species. The Raffles Bulletin of Zoology 62: 210–301
Résumé [+] [-]A worldwide taxonomic and distributional synthesis of the deep-water hermit crab genus Oncopagurus Lemaitre, 1996 is presented. This genus, originally defined for 10 species is set apart from other Parapaguridae as well as other Paguroidea, by one synapomorphy: the presence of an upwardly curved epistomial spine. This study is based on a large amount of specimens deposited in major museums and collected during deep-sea sampling across the world oceans since the late 1800s, with the bulk of material coming from French campaigns in the Indo-Pacific, central and south Pacific during the last 40 years. A total of 24 species are recognised in this investigation, nine of which are new and fully described and illustrated. All previously known species are diagnosed or re-described, including figures assembled from recent published accounts or newly illustrated, of the most important morphological features useful for identifi cations. Information for each species includes a synonymy (full or abbreviated if a synonymy has recently been published), material examined (type and non-types), variations when signifi cant, colouration when available, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Rare colour photographs are included for five species. Species of Oncopagurus range in depth from the Continental Shelf (50 m) to the Continental Rise (2308 m), although they are most commonly found in 50–500 m. Individuals of the majority of species in this genus are minute in size (< 3 mm in shield length), species differ in subtle morphological characters, and often exhibit the same broad morphological variations related to sex and size that has been documented in species of other genera of Parapaguridae. Oncopagurus mironovi Zhadan, 1997, a taxon reported from the Nazca and Sala-y-Gómez Ridges, is considered a junior synonym of the widely distributed O. indicus (Alcock, 1905). The bathymetric and geographic distributions of Oncopagurus species are summarised and briefly discussed, complemented with a summary table, graph, and map with generalised distribution patterns. The scant phylogenetic knowledge of this genus is summarised.

Lemaitre R., Rahayu D.L. & Komai T. 2018. A revision of “blanket-hermit crabs” of the genus Paguropsis Henderson, 1888, with the description of a new genus and five new species (Crustacea, Anomura, Diogenidae). ZooKeys 752: 17-97. DOI:10.3897/zookeys.752.23712
Résumé [+] [-]For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis. The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica, proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n., is justified. As result, the genus Paguropsis is found to contain five species: P. typica, P. andersoni, P. confusa sp. n., P. gigas sp. n., and P. lacinia sp. n. Herein, Paguropsina gen. n., is proposed and diagnosed for two new species, P. pistillata gen. et sp. n., and P. inermis gen. et sp. n.; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species of Paguropsis, and another with the two species Paguropsina gen. n.

Résumé [+] [-]The identity of the tree-spider crab, Parasesarma leptosoma (Hilgendorf, 1869) (family Sesarmidae), which is believed to be widely distributed in the Indo-West Pacific, is reassessed and shown to be a species-complex with nine species, seven of which are here described as new. Parasesarma leptosoma sensu stricto is now restricted to South and East Africa; and P. limbense (Rathbun, 1914) from Sulawesi, which had been regarded as a junior synonym, is here recognized as a valid species. The following species are described as new: P. gecko n. sp. from Vanuatu, Fiji, Guam and Japan; P. macaco n. sp. from Taiwan and the Philippines; P. kui n. sp. from Taiwan; P. parvulum n. sp. from the Philippines; P. gracilipes n. sp. from Indonesian Papua; P. purpureum n. sp. from Malaysia; and P. tarantula n. sp. from Sulawesi, Indonesia. The nine species of the Parasesarma leptosoma species-complex can be separated by the different shapes of their carapaces, the form of the dactylar tubercles on the male chelipeds, proportions of their ambulatory legs and the structure of the male first gonopod.

Résumé [+] [-]Based on the material deposited in the Museum national d'Histoire naturelle, Paris, collected from the Indo-West Pacific, principally from the New Caledonian region, the present paper reports 117 palaemonoid shrimp species, which belong, respectively, to Anchistioididae ( one genus, one species), Gnathophyllidae ( one genus, one species), Palaemonidae Palaemoninae ( seven genera, nine species), and Palaemonidae Pontoniinae ( 30 genera, 106 species), including eight new species. The new species are all Pontoniinae: Mesopontonia brevicarpalis sp. nov., Palaemonella komaii sp. nov., Periclimenes crosnieri sp. nov., Periclimenes forgesi sp. nov., Periclimenes loyautensis sp. nov., Periclimenes paralcocki sp. nov., Periclimenes paraleator sp. nov., and Periclimenes pseudalcocki sp. nov. The last six new species are members of the deep-water "Periclimenes alcocki species complex'', which has more than two ( usually four) pairs of dorsolateral telson spines anterior to the posterior telson margin, the cornea is usually reduced, the dactyl of the major second chela is generally flanged and the chela is sometimes covered with small tubercles. The complex is usually found at more than 200m depth in the West Pacific. The species can be distinguished from each other by the armature of ambulatory propod and dactyl, diameter of cornea, rostrum shape and the number of pairs of dorsolateral telson spines. Mesopontonia brevicarpalis sp. nov., from the southeast coast of Africa, is the seventh species of the genus. Palaemonella komaii sp. nov. is very similar to Palaemonella dolichodactylus Bruce, 1991 and Palaemonella hachijo Okuno, 1999. These three species share the features of very long and slender ambulatory pereiopods with the dactyl more than eight times longer than its basal depth and with several long setae on the dorsal dactylar margin.

Résumé [+] [-]One of the systematically controversial superfamilies in Caridea is the predominately deep-sea or cold water Pandaloidea, largely because this species-rich group of nearly 200 species in 25 genera exhibits a very high diversity of body forms and ecology. Although the relationships amongst the taxa within Pandaloidea have been repeatedly discussed based on morphology, no comprehensive molecular phylogeny exists. In this study, we present the first molecular phylogeny of the group, based on a combined dataset of two mitochondrial (12S and 16S rRNA) and six nuclear (ATP synthase β-subunit, enolase, glyceraldehyde-3-phosphate dehydrogenase, histone 3, phosphoenolpyruvate carboxykinase and sodium–potassium ATPase α-subunit) markers, based on 62 species (about 1/3 of known biodiversity) in 22 genera (88% of genera) of two pandaloid families (Pandalidae, Thalassocarididae) and outgroups from seven other caridean families. With generally high support, the relationships within the clade are fully resolved. Pandalidae is shown to be paraphyletic with Thalassocarididae deeply nested within as a monophyletic group, and the latter is herein considered to be a synonym of Pandalidae. Five major clades are recovered, with the shallow water genera Anachlorocurtis, Chlorocurtis, Chlorotocella and Miropandalus forming a sister clade to the remaining genera. At the genus level, the phylogeny indicates Plesionika, Heterocarpus and Pandalus to be not monophyletic. The validity of Pandalopsis, Stylopandalus and Calipandalus is challenged and these genera are considered herein to be junior synonyms of Pandalus (Pandalopsis) and Plesionika (Stylopandalus and Calipandalus). Although not fully resolved, some evidence potentially considers Nothocaris to be a valid genus. Ancestral State Reconstruction successfully recovered 15 synapomorphies for the major clades, with 11 of them reported to be of systematic significance for the first time.

Résumé [+] [-]The deep-sea genus Ephyrina Smith, 1885, is reported for the first time from Taiwan. The specimens obtained all belong to one species. The Taiwanese material closely resembles E. figueirai Crosnier & Forest, 1973, in having double rows of lateral spines on each side of the telson, but consistently differs from the nominotypical form from the Atlantic in having a longer and more spinose telson,while also the dorsal depression on abdominal somite VI is slightlymore pronounced. Comparison of additional specimens from the Philippines and from Madagascar shows that the West Pacific specimens are nearly identical, but the Madagascan material seems to have characters intermediate between theWest Pacific and Atlantic forms. We decided to propose a subspecific status to the West Pacific population, in order to emphasize the slight but constant differences observed in the telson in this obviously allopatric form of the species.

Résumé [+] [-]The galatheid genus Raymunida Macpherson and Machordom, 2000, is reported for the first time from Taiwan, and the species collected is also new to science. The new species is most closely related to R. confundens Macpherson and Machordom, 2001, but differs in having a more robust cheliped and walking legs covered with distinct squammae. ne coloration of the new species is probably unique in the germs by both the carapace and abdomen being uniform in color. Analysis of the mitochondrial cytochrome oxidase I gene sequences also supports the specific status of this Taiwanese form.

Résumé [+] [-]Nihonotrypaea thermophila, new species, is described on the basis of 26 specimens from a hydrothermally influenced field off northeastern Taiwan at depths of 128–320 m. This is the first callianassid shrimp to be reported from deep-water hydrothermal vents, and available data seems to suggest that the new species is vent-endemic. The new species is assigned to Nihonotrypaea Manning & Tamaki, 1998, a genus including three previously described species inhabiting coastal mud or sand flat areas in Japan and its adjacent waters. The new species is unique in the genus in having the antennal peduncle distinctly longer than the antennular peduncle.

Résumé [+] [-]Recent advancements in deep-sea expeditions have made possible to sample adequate quantities of deep-sea organisms over wide geographical ranges for population genetic studies. Scalpellum stearnsii is a common stalked barnacle that occurs in the mesobenthic environment (>200 m depth) throughout the West Pacific Ocean and covers several major deep-sea basins. The present study examined the diversity and genetic differentiation of S. stearnsii populations from the East China Sea, West Philippine Basin, Sulu Sea, and Caroline Trenches. Mo lecular analyses based on partial sequences of the mitochondrial gene COI and nuclear gene H3 revealed four distinct clades of S. stearnsii—SS, CF1, CF2, and CF3—with distinct species-level pairwise divergences among the clades. SS (representing S. stearnsii, based on morphological comparison with holotype) is mainly present in the East China Sea and the Philippine Basin, CF1 is present in the East China Sea, CF2 is present in the Sulu Sea, and CF3 is exclusively present in the Caroline Trench (Southwest Pacific Ocean). Deep genetic differentiation be tween the northern (SS and CF1) and southern clades (CF2 and CF3) was estimated to have occurred around 33 million years ago, and the eastward-flowing Equatorial Undercurrent (100–200 m) and oxygen minimum zone (300–400 m) are the putative barriers to gene flow. The timing is concordant with reported diversification events in both shallow- and deep-water organisms during the Oligocene and Miocene periods. This cross-ocean, -taxon, and -habitat divergence time suggests speciation driven by global-scale events. Recent size expansion likely occurred in all the four clades and subsequent populations, predating the Last Glacial Maximum (LGM). The persistence of mesobenthic deep-sea barnacles through the temperature fluctuation at the LGM can be a common pattern.

Résumé [+] [-]Bathymodiolin mussels occur at hydrothermal vents and cold seeps, where they thrive thanks to symbiotic associations with chemotrophic bacteria. Closely related genera Idas and Adipicola are associated with organic falls, ecosystems that have been suggested as potential evolutionary 'stepping stones' in the colonization of deeper and more sulphide-rich environments. Such a scenario should result from specializations to given environments from species with larger ecological niches. This study provides molecular-based evidence for the existence of two mussel species found both on sunken wood and bones. Each species specifically harbours one bacterial phylotype corresponding to thioautotrophic bacteria related to other bathymodiolin symbionts. Phylogenetic patterns between hosts and symbionts are partially congruent. However, active endocytosis and occurrences of minor symbiont lineages within species which are not their usual host suggest an environmental or horizontal rather than strictly vertical transmission of symbionts. Although the bacteria are close relatives, their localization is intracellular in one mussel species and extracellular in the other, suggesting that habitat choice is independent of the symbiont localization. The variation of bacterial densities in host tissues is related to the substrate on which specimens were sampled and could explain the abilities of host species to adapt to various substrates.

Résumé [+] [-]Based on new material from the western Pacific and Indian Oceans, the deep-sea scavenging genus Bathynomus is revised. Six species are redescribed: Bathynomus affinis Richardson, 1910 (range extended to the Arafura and Timor Seas), B. decemspinosus Shih, 1972, B. doederleini Ortman, 1894 (range extended to San Bernardino Strait, Philippine Islands), B. immanis Bruce, 1986 (range extended to Astrolabe Bay, Bismarck Sea), B. kapala Griffin, 1975 (range extended to off the Great Barrier Reef, Coral Sea) and B. pelor Bruce, 1986. Bathynomus propinquus Richardson, 1910 is considered to be a nomen dubium. Six new species are described: B. brucei n. sp. from off the Great Barrier Reef, Coral Sea; B. bruscai n. sp. from off the Great Barrier Reef, Coral Sea and Astrolabe Bay, Bismarck Sea; B. crosnieri n. sp. from off Madagascar, western Indian Ocean; B. keablei n. sp. from off the Malabar Coast, Arabian Sea; B. kensleyi n. sp. from the South China Sea, the Sulu Sea and the Coral Sea; B. richeri n. sp. from off New Caledonia, plus Bathynomus sp. from the Gulf of Aden. Bathynomus giganteus A. Milne Edwards, 1879 is reported for the first time from the east coast of the United States. Two distinct groups occur in Bathynomus, a lineage of giant species which mature at about 150 mm length and a lineage of supergiant species which can grow to 500 mm in length. The greatest diversity of Bathynomus occurs between latitudes 20°N and 20°S on the Indian-Australian plate. Outlying species occur on plates in the western North Pacific and the western Atlantic.

Résumé [+] [-]The uristid genus Ichnopus is revised and Glycerina included in its synonymy. A key is provided to the world species. Ichnopus pelagicus Schellenberg, I. pseudoserricrus Ledoyer, I. serricrus Walker, I. spinicornis Boeck, I. taurus Costa, (type species), I. tenuicornis (Haswell), I. teretis (Andres) and I. woodmasoni (Giles) are redescribed. The new species I. annasona, I. capricornus, I. caritus, I. comorensis, I. cribensis, I. malpatun, I. parriwi and I. wardi are described. Ichnopus nossibeensis Ledoyer is considered to be a synonym of I. pelagicus. Ichnopus macrobetomma Stebbing is considered to be an unrecognisable species. Two species groups are recognised: the I. spinicornis group, in which the ischium and carpus of gnathopod 1 are long and most species are pelagic, probably micropredators; and the I. taurus group, in which the ischium and carpus of gnathopod 1 are very long and most species are demersal scavengers. Ichnopus is considered to be . A tropical to warm temperate Indo-Pacific genus with some remnants in the Mediterranean and the eastern North Atlantic Ocean. The most primitive species in both groups are found in the Mediterranean Sea and the eastern North Atlantic. It appears that the modern genus had its origins in the old Tethyan fauna.

Résumé [+] [-]The first comprehensive phylogenetic study of the family Oplophoridae is based on four molecular markers and 87 morphological characters. We have examined and coded five major groups of morphological characters related to the rostrum (nine characters), the carapace (10), the abdomen and telson (34), the exopods (eight) and the armature of the posteriormost three pereopods (22). Abdomen/telson-linked characters are the most important in support of genus level and species-group level clades; abdomen/telson-linked, rostrum-linked characters and the armature of the last three pereopods explain the main bulk of speciation. Four robustly supported species groups within Systellaspis are designated: the S. debilis species group, the S. cristata species group, the S. braueri species group and the S. pellucida species group. We provide an amended key to all genera, species groups and species of Oplophoridae. We reveal three groups of morphological characters, which are likely coupled with the same locomotive function and thus evolved as a single unit: carapace, abdomen and exopods. We show that the armature of the posteriormost three pereopods evolved independently of other characters and suggest that this group is linked to such biological roles as mating and grooming.

Zoological Journal of the Linnean Society 187(4): 1155-1172. DOI:10.1093/zoolinnean/zlz070
Résumé [+] [-]Abstract The phylogenetic study of the deep-sea genus Bentheogennema is based on four molecular markers and 79 morphological characters. All four previously recognized species and two new species of Bentheogennema, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. We have examined and coded six major groups of morphological characters related to the carapace (three characters), the pleon and the telson (14), the mouthparts (nine), the armature of the pereopods (five), the thelycum (27) and the petasma (21). Results of morphological and molecular analyses were similar. Two species were transferred from Bentheogennema to other genera (for one of them a new genus was erected) and two new species of Bentheogennema were described. Three pelagic genera (Gennadas, Bentheogennema and a new genus) created a robust clade. The divergence of this clade is linked to ‘smoothening’ of the body (reduction of the branchiostegal spine on the carapace, reduction and loss of the dorsolateral spines and the end-piece on the telson) and elaboration of the copulatory structures. We provide amended diagnoses of these three pelagic genera and key to species of Bentheogennema.

Résumé [+] [-]Abstract The shrimp genera Ephyrina, Meningodora and Notostomus have an unusual carapace strengthened with carinae and a half-serrated mandible, which may suggest a possible monophyly of this group. Here we test this hypothesis and present the first phylogenetic study of these genera based on 95 morphological characters (all valid species coded) and six molecular markers (71% of valid species sequenced). Representatives of all genera of Oplophoridae (sister to Acanthephyridae) were outgroups, 32 species belonging to all genera and potentially different clades of Acanthephyridae were ingroups. Both morphological and molecular analyses retrieve trees with similar topology. Our results reject the hypothesis of a clade formed by Ephyrina + Meningodora + Notostomus. We show that Ephyrina and Notostomus are monophyletic, both on morphological and on molecular trees, Meningodora gains support only on morphological trees. Evolutionary traits in the Ephyrina and Meningodora + Notostomus clades are different. Synapomorphies are mostly linked to adaptations to forward motion in Ephyrina (oar-like meri and ischia of pereopods, stempost-like rostrum) and to progressive strengthening of the carapace and pleon in Meningodora and Notostomus (net of sharp carinae). Unusual mandibles evolved in the clades independently and represent convergent adaptations to feeding on gelatinous organisms.

Résumé [+] [-]Penaeoidea is a diverse group of economically important marine shrimps. Attention to the evolutionary history of the penaeoids has been raised since studies using mitochondrial DNA markers and sperm ultrastructure contradict classification of the penaeoid families based on morphology and hence challenge the long standing taxonomy of this superfamily. In this study, DNA sequences of two nuclear protein-coding genes, phosphoenolpyruvate carboxykinase and sodium-potassium ATPase alpha-subunit, were determined from 37 penaeoid genera to reconstruct the evolutionary relationships and to estimate divergence ages of the penaeoid shrimps. Phylogenetic analyses using maximum likelihood and Bayesian approaches strongly support the monophyly of Solenoceridae, Aristeidae and Benthesicymidae, but find Sicyoniidae nested within Penaeidae, making this family paraphyletic. Penaeoidea comprises two lineages: the former three families in one while the latter two in another. The diversification of these lineages may be related to bathymetry. The penaeid-like lineage diversified in the Triassic, earlier than the aristeid-like lineage with an origin in the Jurassic. Taxonomic revisions within Penaeoidea are also proposed for further investigation. Due to the paraphyly of Penaeiclae and the high genetic divergence among the three penaeid tribes of Burkenroad [Burkenroad, M.D., 1983. Natural classification of Dendrobranchiata, with a key to recent genera. In: Schram, F.R. (Ed.), Crustacean Issues 1. Crustacean Phylogeny. A.A. Balkema, Rotterdam, pp. 279-290], these tribes should be treated as having the same taxonomic rank as Sicyoniidae, while the family ranking of Benthesicymidae has to be re-considered owing to the low genetic divergence between the benthesicymids and the aristeids.

Journal of Biogeography 45(12): 2658-2668. DOI:10.1111/jbi.13443
Résumé [+] [-]Aim: The high species richness of the Indo‐Australian Archipelago (IAA) marine biodiversity hotspot has been attributed to three competing hypotheses: Centre of Origin/Centre of Overlap/Centre of Accumulation. While most phylogeographic studies testing these hypotheses have focused on marine fishes, we provide a new perspective on this evolutionary important question by examining the population genetics of the horned ghost crab Ocypode ceratophthalmus sensu lato (Ocypodidae) whose distribution spans the entire Indo‐Pacific and contains at least two colour morphs.

Résumé [+] [-]Two new species of the hermit crab genus Lithopagurus Provenzano, 1968 are described and illustrated together with an illustrated and detailed diagnosis of the type species, L. yucatanicus Provenzano, 1968 that is included for comparative purposes. This genus, heretofore monotypic and known only from off the Atlantic coast of Mexico, is now reported from two widely separated Pacific areas, the Indonesian Kai Islands and the Fiji Islands. In having 13 pairs of gills and one pair of pleopods modified as gonopods, Lithopagurus is included in the Pylopaguropsis group within the family Paguridae, and would appear most closely allied to the monotypic Tomopaguroides Balss, 1912. Species of Lithopagurus are very characteristic, with large operculate or semioperculate right chelipeds, reduced and somewhat bulbous pleons; males with paired and modified second pleopods, but lacking all unpaired pleopods; females with only unpaired pleopods 2-4; and telsons without lateral indentations and with terminal margins lacking median clefts. Lithopagurus boucheti n. sp., from the Fiji Islands, is morphologically quite similar to its Atlantic counterpart, L. yucatanicus, whereas L. tribulomanus n. sp., from the Kai Islands, is very distinctive. All three now recognized species have been collected from relatively deep water, 146-540 m, but little is known about their habitats other than one specimen of L. yucatanicus reportedly was occupying a piece of lithistid sponge at the time of collection.

Résumé [+] [-]A new genus, Pteropagurus, is proposed for two new species of hermit crabs that are described and illustrated herein. These species, Pteropagurus inermis n. sp. and P. spina n. sp. are unique in that their shelter of choice is empty pteropod mollusk shells. The taxon can be categorized as a deep-waters genus, with a bathymetric range of 285 to 700 meters. Although both species are presently known only from New Caledonia, it is quite possible that their occurrence in other areas has been overlooked because their unique habitat has been neither expected nor heretofore considered a resource for hermit crabs.

Résumé [+] [-]A large collection of species of the genus Munida has been examined and found to contain 56 undescribed species. The specimens examined were caught mainly off New Caledonia, Chesterfield Islands, Loyalty Islands, Matthew and Hunter Islands. Several samples from Kiribati, the Philippines and Indonesia have also been included. The specimens were collected between 6 and 2 049 m. Some species previously known in the area (Af. Gracilis, M. haswelli, M. microps, M. spinicordata and M. tubercidata) have been illustrated. These results point up the high diversity of this genus in the region and the importance of several characters in species identification (e.g., size and number of lateral spines on the carapace, ornamentation of the thoracic sternites, size of antennular and antennal spines, colour pattern).

Macpherson E. & Machordom A. 2000. RAYMUNIDA, NEW GENUS (DECAPODA: ANOMURA: GALATHEIDAE) FROM THE INDIAN AND PACIFIC OCEANS. JOURNAL OF CRUSTACEAN BIOLOGY 20(special number 2): 253-258
Résumé [+] [-]A new galatheid genus, Raymunida, is established for two known species, Munida elegantissima de Man, 1902, and M. bellior Miyake and Baba, 1967, and one new species, R. cagnetei from the Marquesas Islands (French Polynesia, Pacific Ocean). This new genus is easily distinguished from the genus Munida Leach, 1820, and other galatheid genera by the following combination of characters: (1) the presence of epipods on first, second, and third pereiopods; (2) one spine on the frontal margin between supraocular and anterolateral spines; (3) one distal spine on the flexor margin of the carpus of the third maxilliped; (4) the merus of the second pereiopod clearly more slender than those of third and fourth pereiopods; and (5) the presence of several long marginal spines on the endopod of the uropods. Raymunida cagnetei, new species and type species of the genus, is clearly distinguishable from the other species of the genus by the colour pattern, the presence of long setae on the carapace and abdomen, the length of the propodus of the walking legs, and the number of striae on the abdominal somites.

Macpherson E. 2001. New species and new records of lithodid crabs (Crustacea, Decapoda) from the southwestern and central Pacific Ocean. Zoosystema 23(4): 797-805
Résumé [+] [-]Six species of litholid crabs from New Caledonia, Vanuatu, Fiji and French Polynesia are studied. Two new species, Paralomis arae n. sp. and P. dawsoni n. sp., are described. Four other species, Lithodes richeri, Neolithodes brodiei, N. nipponensis and Neolithodes sp., are reported fot the first time from these localities. P. arae n. sp. has the carapace and the abdomen surfaces covered with small granules of various size and it is caracterized by the presence of few scattered spines on the gastric region. The walking legs are moderately long, having well-developed spines along dorsal and ventral margins of merus and propodus. The closest species is P. verrilli from the northeastern Pacific (Bering Sea to California), but they are differentiated by the shape and armature of the carapace and the lenght of the dactylus of the walking legs. P. dawsoni n. sp. has the carapace, abdomen and pereipods surfaces covered with clusters of rounded granules of different sizes. This new species is closely related to P. granulosa from the southern coasts of Argentina and Chile. Both species are easily distinguished by the armature of the carapace, scaphocerite and pereipods and the length of the walking legs.

Macpherson E. & Machordom A. 2001. Phylogenetic relationships of species of Raymunida (Decapoda: Galatheidae) based on morphology and mitochondrial cytochrome oxidase sequences, with the recognition of four new species. Journal of Crustacean Biology 21(3): 696-714. DOI:10.1651/0278-0372(2001)021[0696:PROSOR]2.0.CO;2
Résumé [+] [-]The species of the genus Raymunida from the Pacific and Indian oceans are revised using morphological characters and the mitochondrial cytochrome oxidase subunit I sequences. Four new species are described (R. confundens. R. dextralis, R. erythrina, and R. insulata), and the status of R. bellior and R. elegantissima are revised. The species of Raymunida can be identified by subtle morphological characters, which match differences in mitochondrial nucleotide sequences. Therefore. the sequence divergences confirm the specific and phylogenetic value of some morphological characters (e.g., length of the mesial spine on the basal antennal segment, length of the walking legs). Furthermore. they confirm the importance of the color pattern as a diagnostic character. The widespread species (R. elegantissima), known from the Philippines to Fiji, shows minimal divergence between specimens from different localities (maximum of 3 nucleotide differences or 0.2% mean divergence). The phylogenetic reconstruction agreed with the monophyletic condition of Raymunida and its differentiation with respect to the genus Munida (in which Raymunida species had previously been included) and Agononida.

Résumé [+] [-]Four species of Litholid crabs from the Solomon Islands were collected during the Solomon I cruise carried out off the Solomon Islands. One new species, Paralomis mendagnai, is described and illustrated. Three other species, Neolithodes nipponensis, Paralomis dawsoni and P. haigae, are reported for the first time from these islands. The new species of Paralomis closely resembles P. medipacifica Takeda, 1974, from Midway Islands (Central Pacific) and is characterised by the dorsal surface of the carapace thickly covered with rounded, more or less prominent granules of different sizes. Both species are easily distinguished by the armature of the scaphocerite and pereiopods. A key to the species of the genus Paralomis from the western and central Pacific Ocean is presented.

Résumé [+] [-]Three cryptic species of the genus Munida from New Caledonia, previously identified as M. tuberculata Henderson, 1885, M. notata Macpherson, 1994 and M. clinata Macpherson, 1994, are described and illustrated. The three species are identified by subtle and constant morphological characters, which match clear differences in molecular sequences (16S rDNA and COI genes). The results also confirm the importance of several of these characters (e.g. length of the antennular and antennal spines) in the taxonomy of the genus Munida.

Macpherson E. 2006. New species and new occurrences of Galatheoidea (Crustacea, Decapoda) from New Caledonia. Zoosystema 28(3): 669–681
Résumé [+] [-]Four new species of the genera Eumunida Smith, 1883 (E. spinosa n. sp.), Munida Leach, 1820 (M. aulakodes n. sp., M. devestiva n. sp.) and Torbenia Baba, 2005 (T. calvata n. sp.) are described and illustrated from specimens collected during recent cruises carried out off New Caledonia. Eumunida spinosa n. sp. has two well developed spines on the anterior border of the fourth thoracic sternite (subgenus Eumunida de Saint-Laurent & Poupin, 1996), the posterior region of the carapace with complete striae, the carapace with two pairs of anterolateral spines, no ventral pad on the propodus of the chelipeds, and two rows of well developed spines on the palm of the cheliped. Munida aulakodes n. sp. is characterized by the presence of three spines on the branchial lateral margins of the carapace, spines on the anterior ridge of the second abdominal somite, and two carinae separated by a furrow, on each lateral part of the seventh thoracic sternite. Munida devestiva n. sp. has a carapace without complete transverse ridges, small eyes, with the corneae barely wider than the eyestalk, and the abdominal segments unarmed. Torbenia calvara n. sp. is easily differentiated from the other species of the genus by the absence of spines on the anterior ridge of the second abdominal segment, and the small size of the first anterolateral spine of the carapace. A new occurrence of the rare species Pseudomunida fragilis Haig, 1979 is also reported.

Résumé [+] [-]Three new species of squat lobsters are described and illustrated from specimens collected during recent cruises carried out in the Southwest and Central Pacific. Anoplonida patae n. sp. has a well developed cardiac process, pairs of both epigastric spines and postcervical processes, one or two flexor marginal spines on the mxp 3 merus, and a single distolateral spine on the antennular basal article. Bathymunida avatea n. sp. is characterized by the dorsal surface of the carapace having numerous scale-like ridges, the distomesial spine of the basal article of the antennal peduncle reaching the end of article 2, and the distolateral spine of article 2 reaching the mid-length of article 3. Heteronida clivicola n. sp. has each posterior branchial region of the carapace without a distinct elevation, the gastric process being low and rounded, and the disto lateral margin of antennal article 2 strongly produced, nearly reaching the end of article 3. New records of seven species (Anoplonida inermis, Bathymunida sibogae, Heteronida aspinirostris, Neonida grandis, Onconida modica, O. tropis and Plesionida psyla) also are reported.

Résumé [+] [-]Sixty-six species of the genus Munidopsis have been studied using specimens collected during numerous French expeditions carried out in the last decades in the deep-waters of the southwest Indian and southwest Pacific Oceans, between 140 and 4400 m. Twenty-five new species are described, and the diagnoses and illustrations of some relatively rare species (M. africana, M. debilis, M. lenzii, M. moresbyi, M. orcina, M. sinclairi, M. stylirostris and M. wardeni) are provided. The reestablishment of the genus Galacantha is proposed, including the descriptions/diagnoses and a key to all species. The genus contains nine species, including three new species (G. bellis, G. diomedeae, G. quiquei n. sp., G. rostrata, G. spinosa, G. subrostrata n. sp., G. subspinosa n. sp., G. trachynotus and G. valdiviae). The number of species collected by station is very small (usually one species), probably related to their low densities. However, in some samples, as many as five species have been found. The highest number of species have been observed in the Banda Sea (Indonesia) and Solomon Islands. The new records of some species greatly extend the previously known distribution range of the species.

Résumé [+] [-]Seven species of Lithodid crabs were collected during cruises off Taiwan and Guam. One new species, Lithodes paulayi is described and illustrated. Neolithodes nipponensis, Lithodes sp., Paralomis arae, P. dofleini and P. truncatispinosa are reported from these islands for the first time, extending the distributional range in each case. Lithodes paulayi closely resembles L. longispina Sakai, 1971, from off Japan and the central Pacific, but can be differentiated by the branchial region possessing two long dorsal spines and only one long marginal spine, whereas L. longispina has only one long dorsal spine, situated at level of cardiac spines, and two long marginal spines. The description of a juvenile of P. arae Macpherson, 2001, is also included.

Résumé [+] [-]Two new species of squat lobsters are described. Agononida rubrizonata n. sp. from Taiwan, Vanuatu, New Caledonia, Queensland and New South Wales, is distinguished from A. incerta (Henderson, 1888) by the male telson with a strong anterolateral process and different color pattern, although females of the two species are not morphologically separable. In order to establish the taxonomic status of A. incerta originally described from a female holotype, topotypic material is described. Paramunida leptotes n. sp. from the Izu Islands off Honshu, Japan, the Kyushu-Palau Ridge, off Amami-oshima of the Ryukyus, and Taiwan is distinguished from P. proxima (Henderson, 1885) by the absence instead of presence of a spine on the posterior ridge of the fourth abdominal somite and much narrower and more elongate third antennal segment that is at least 1.5 times longer than instead of as long as broad and about half instead of two-thirds as broad as the article 2.

Résumé [+] [-]Seven new species of the genera Munida Leach, 1820 (M. acola n. sp., M. clevai n. sp., M. jubata n. sp., M. mica n. sp., M. pauxilla n. sp. and M. squarrosa n. sp.) and Raymunida Macpherson & Machordom, 2000 (R. vittata n. sp.) are described and illustrated from specimens collected during recent cruises carried out off Vanuatu. Munida acola n. sp. has the second abdominal somite unarmed, distal spines of the antennular peduncle unequal in size, and the P2-P4 dactyli with spines along the entire ventral border. Munida clevai n. sp. has small eyes, and spines on the anterior ridge of second abdominal somite. Munida jubata n. sp. is characterized by the presence of spines on the second abdominal somite, and unequally sized distal spines of antennular peduncle. Munida mica n. sp. and M. pauxilla n. sp. have the frontal margin oblique, abdominal somites Unarmed, and distal spines of antennular peduncle of different size. Munida squarrosa n. sp. has the second abdominal segment with spines, and the distal half of the ventral border of P2-P4 dactyli unarmed. Raymunida vittata n. sp. belongs to a group of species having the mesial spine of first antennal segment not reaching the end of the basal segment of antennular peduncle, and mero-carpal articulation of P4 nearly reaching the frontal margin of the carapace.

Résumé [+] [-]We analyzed the distribution patterns of the galatheid squat lobsters (Crustacea, Decapoda, Galatheidae) of the Pacific Ocean. We used the presence/absence data of 402 species along the continental slope and continental rise (200-2000 m) obtained from 54 cruises carried out in areas around the Philippines, Indonesia, Solomon, Vanuatu, New Caledonia, Fiji, Tonga, Wallis and Futuna and French Polynesia. The total number of stations was ca. 3200. We also used published data from other expeditions carried out in the Pacific waters, and from an exhaustive search of ca. 600 papers on the taxonomy and biogeography of Pacific species. We studied the existence of biogeographic provinces using multivariate analyses, and present data on latitudinal and longitudinal patterns of species richness, rate of endemism and the relationship between body sizes with the size of the geographic ranges. Latitudinal species richness along the Western and Eastern Pacific exhibited an increase from higher latitudes towards the Equator. Longitudinal species richness decreased considerably from the Western to the Central Pacific. Size frequency distribution for body size was strongly shifted toward small sizes and endemic species were significantly smaller than non-endemics. This study concludes that a clear separation exists between the moderately poor galatheid fauna of the Eastern Pacific and the rich Western and Central Pacific faunas. Our results also show that the highest numbers of squat lobsters are found in the Coral Sea (Solomon-Vanuatu-New Caledonia islands) and Indo-Malay-Philippines archipelago (IMPA). The distribution of endemism along the Pacific Ocean indicates that there are several major centres of diversity, e.g. Coral Sea, IMPA, New Zealand and French Polynesia. The high proportion of endemism in these areas suggests that they have evolved independently. (C) 2009 Elsevier Ltd. All rights reserved.

Résumé [+] [-]A revision of the genus Sadayoshia Baba, 1969 (type species: S. miyakei Baba, 1969) is carried out based on more than 460 specimens from numerous localities in the Indo-Pacific, revealing the existence of seven species. Sadayoshia edwardsii (Miers, 1884) is redescribed using material collected near the type locality (SW Indian Ocean) and from numerous localities from the Indian and Pacific Oceans. The three previously described species (S. acroporae, S. balica, and S. miyakei) proved to be valid species. Four additional species are described here as new to science: S. latisternata n. sp. from French Polynesia, Loyalty Islands and Mauritius Island; S. lipkei n. sp. from French Polynesia, Solomon Islands, Vanuatu, New Caledonia, Loyalty Islands and Chesterfield Islands; S. inermis n. sp. from Solomon Islands, Vanuatu and New Caledonia; and S. tenuirostris n. sp. from Japan, South China Sea, Palau Islands, Philippines, Indonesia, Solomon Islands, Vanuatu and New Caledonia.

Résumé [+] [-]During two cruises to Vanuatu, MUSORSTOM 8 (September-October 1994) and SANTO 2006 (September-October 2006), numerous specimens of deep-sea galatheids belonging to the genus Galathea Fabricius, 1793 were collected. The specimens were caught at stations at depths between 180 and 702 m. These collections contain five new species (G. barbellata n. sp., G. echinata n. sp., G. profunda n. sp., G. raventosae n. sp. and G. sanctae n. sp.), all of which are also found in other collections obtained by French cruises to New Caledonia. Galathea barbellata n. sp., G. echinata n. sp. and G. profunda n. sp. are closely related to G. robusta Baba, 1990, from Madagascar, G. raventosae n. sp. resembles G. consobrina De Man, 1902, from Indonesia, the Philippines, South China Sea and SW Australia, and G. sanctae n. sp. is very close to G. multilineata Balss, 1913, from Japan, East China Sea, Taiwan and the Philippines.

Résumé [+] [-]Careful examination of the morphology of recently obtained specimens as well as previously reported specimens of the genus Sadayoshia, initiated by unpublished molecular data that suggest the existence of several different species, led us to describe six new species. The species are very similar to one another and distinguished by very slight morphological differences. Some of the characters that were previously considered as intraspecifically variable in some species, proved to be valid for species discrimination. A dichotomous key to all species of the genus is provided.

Résumé [+] [-]The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other collections from various sources, and including the type specimens of some previously described species. Most of the new species are distinguished by subtle but constant morphological differences, which are in agreement with molecular divergences of the mitochondrial markers COI and/or 16S rRNA. Here, we describe and illustrate the new species and redescribe some previously described species for which earlier accounts are not sufficiently detailed for modern standards. Furthermore we include a dichotomous identification key to all species in the genus from the Indian and Pacific Oceans.

Résumé [+] [-]The hairy crab Pilumnus vinaceus A. Milne-Edwards, 1880, previously considered to be a junior synonym of Pilumnus dasypodus Kingsley, 1879 by Rathbun (1897) is here resurrected. Pilumnus vinaceus can be distinguished from the known western Atlantic species (including P. dasypodus) based on morphological characters and molecular markers. This action increases number of reported species of Pilumnus in the western Atlantic to nineteen.

Résumé [+] [-]The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role of ecology in speciation, and patterns of species distribution in a typical reef-associated clade-the diverse and colorful Calcinus hermit crabs-to address the origin of tropical marine diversity. We sequenced COI, 16S, and H3 gene regions for similar to 90% of 56 putative species, including nine undescribed, "cryptic" taxa, and mapped their distributions. Speciation in Calcinus is largely peripatric at remote locations. Allopatric species pairs are younger than sympatric ones, and molecular clock analyses suggest that > 2 million years are needed for secondary sympatry. Substantial niche conservatism is evident within clades, as well as a few major ecological shifts between sister species. Color patterns follow species boundaries and evolve rapidly, suggesting a role in species recognition. Most species prefer and several are restricted to oceanic areas, suggesting great dispersal abilities and giving rise to an ocean-centric diversity pattern. Calcinus diversity patterns are atypical in that the diversity peaks in the west-central oceanic Pacific rather than in the Indo-Malayan "diversity center." Calcinus speciation patterns do not match well-worn models put forth to explain the origin of Indo-West Pacific diversity, but underscore the complexity of marine diversification.

Résumé [+] [-]A new species of Calcinus is described from western Pacific material, including specimens previously identified as Calcinus anani Poupin & McLaughlin, 1998. The new species C. fuscus n. sp. differs from C. anani in the colouration in life, and their specific distinction is genetically supported by the barcoding gene cytochrome oxidase I (COI). The two species also have different geographic distributions, with C. fuscus n. sp. ranging from Japan to the Philippines, Papua New Guinea, and New Caledonia, while C. anani is restricted to French Polynesia. Moreover C. fuscus n. sp. is found at shallower depths than its sister species C. anani.

New insights into the molecular phylogeny of the swimming crabs of the genera Portunus Weber, 1795 and Achelous De Haan, 1833 (Brachyura: Portunidae) of the Americas. Journal of Crustacean Biology 38(2): 190-197. DOI:10.1093/jcbiol/rux119
Résumé [+] [-]Earlier studies of swimming crabs (family Portunidae) in the Americas suggested polyphyly of Portunus Weber, 1795. Our previous molecular analyses provided evidence for a subdivision of the genus, resulting in a reassignment of nine species of Portunus and one species of Cronius Stimpson, 1860 into the resurrected genus Achelous De Haan, 1833. These previous data also suggested that at least two more clades of species could be separated from Portunus sensu stricto. Our sampling efforts provided 11 additional (of potentially 12) eastern Pacific species originally treated under Portunus, which we herewith included in a new molecular phylogenetic analysis based on sequences of the 16S rRNA gene. With these additions, we present molecular data of almost all American species of Portunus sensu lato and contextualize them within the family Portunidae. Our findings strongly corroborate previous conclusions about the polyphyletic nature of Portunus. Some of the newly included species fit well into the clade previously defined as Achelous, whereas others are clearly assignable to clades that remain to be named. While we acknowledge the absence of most of the Indo-West Pacific species in our analyses, we can on the basis of morphology hypothesize that some of these Indo-West Pacific species (and valid subgenera) should cluster within the here-established clades.

Zootaxa 3835(3): 301-324. DOI:10.11646/zootaxa.3835.3.1
Résumé [+] [-]The new pontoniine shrimp genus, Echinopericlimenes gen. nov., is suggested for four species, Periclimenes hertwigi Balss, 1913, Periclimenes dentidactylus Bruce, 1984, Periclimenes calcaratus Chace & Bruce, 1993 and Echinopericlimenes aurorae sp. nov., belonging to so-called “Periclimenes hertwigi Balss, 1913” species group sensu stricto. The new genus can be clearly separated by the unique form of hepatic tooth greatly extending beyond the pterygostomial margin of carapace, unique form of fingers of pereiopods II (chelipeds) and dactyli of ambulatory pereiopods III–V. All species referring to the new genus are similar in ecology being deep-water dwellers, usually collected deeper that 300 meters in associations with venomous sea urchins of the family Echinothuriidae (Echinodermata: Echinoidea). Remarks on ecology, description of the new species from Philippines and a key to all known species of Echinopericlimenes gen. nov. are presented.

Mémoires du Muséum national d'Histoire naturelle 172:433-572, ISBN:2-85653-506-2
Résumé [+] [-]The French-Indonesian 1991 campagne to the islands of Kai, Aru, and Tanimbar, part of the Maluku region of Indonesia, revealed an unexpected wealth of hermit crabs of the family Paguridae. Although only 295 specimens were collected in depths ranging from 85 to 1024 meters, an incredible 19 genera and 36 species are represented, of which seven genera and 26 species are described for the first time. Included are the monotypic Alainopaguroides gen. nov., Enneopagurus gen. nov., Enneophyllus gen. nov., lcelopagurus gen. nov., and Tarrasopagurus gen. nov., and their respective new species. The genus Michelopagurus, gen. nov., is established for "Pagurodes" limatu lus Henderson, 1888, and one additional new species, and the genus Pseudopagurus is created for "Pagurodes" piliferus Henderson, 1888, the last of the original trio of species initially assigned to the heterogeneous Pagurodes. A lectotype for Pagurodes inarmatus Henderson, 1888, the type species of the now monotypic Pagurodes, is also designated. The genus Turleania is proposed as a replacement name for Laurentia McLaughlin & Haig. Of the new genera, three are particularly noteworthy. Not only are Enneopagurus and Enneophyllus just the second and third genera of the Paguridae to be characterized, in part, by the absence of gills on the third maxillipeds, the latter genus is unique, at least for the present. !ts type species. E. spinirostris sp. nov., is the first pagurid known to have a weil developed epi-rostral spine. Alainopaguroides joins that very specialized group of genera distinguished by marked reduction in the abdomen, accompanied by total loss of male pleopods and reduction in the number of female pleopods. Two additional genera of this group, Solitariopagurus and Porcellanopagurus, are also represented in the KARUBAR collection, each by a new species. In addition to the new genera, new species are described in several of the less commonly reported genera, e.g., Catapaguroides, Decaphyllus, Catapagurus, and Tomopaguropsis. Although Pagurus is widely represented in the colder waters, particularly of the northern hemisphere, the discovery of three new species from the restricted geographic region of the KARUBAR campagne was unexpected. A third species has been added to, and extends the distributional range of, the recently described Bathypaguropsis from Australian and New Zealand waters. A new species described in Australeremus has provided continuity to the heretofore disjunct distribution of this genus. Only one genus, Pylopaguropsis, was represented entirely by known species.The KARUBAR collection is also significant for its number of highly evolved genera. Specifically, development of the male sexual tube(s) is uncommonly prevalent. In the 19 genera included in the collection, males of 13 develop a sexual tube on one or both coxae of the fifth pereopods, or nearly two-thirds of the total genera. All species are fully illustrated and detailed descriptions or diagnoses provided. Keys are provided for the regional genera and species, including those reported from the Maluku area, but not included in the KARUBAR collection.

Mémoires du Muséum national d'Histoire naturelle 184:389-414, ISBN:2-85653-526-7
Résumé [+] [-]The very interesting and rather specialized hermit crab genera Porcellanopagurus and Solitariopagurus are represented in collections from the MUSORSTOM cruises to New Caledonia and the Marquesas by four species of the former and three of the latter. Among the species of Porcellanopagurus, three species, P. tridentatus Whitelegge, P. filholi de Saint Laurent & McLaughlin, and P. chiltoni de Saint Laurent & McLaughlin have heretofore been reported only from Australia and New Zealand; P. haptodactylus sp. nov. is a distinctive species, new to science. Solitariopagurus triprobulus Poupin& McLaughlin is reported for the first time beyond the islands of French Polynesia, and the range of S. tuerkayi McLaughlin is extended from the Kai and Tanimbar Island of Indonesia to New Caledonia, Vanuatu and Okinawa. A new species, S. trullirostris sp. nov., is described from New Caledonia and the Marquesas. The similarities and differences of the two new genera are elucidated, and an apparently rare attribute, a terminal anus, common to some species of both is discussed. The new species are fully described and illustrated, while diagnoses and illustrations of principal diagnostic characters are provided for the previously described species. Keys to the Indo- and western Pacific species of Porcellanopagurus and to the genus Solitariopagurus are included.

Résumé [+] [-]The discovery of a new species from the waters of eastern Australia and New Caledonia has required a reassessment of the merit of the reinstatement of the hermit crab genus Hemipagurus Smith, 1881. Reappraisal of all characters ascribed to both Catapagurus A. Milne-Edwards, 1880 and Hemipagurus, in light of the attributes of Catapagurus franklinae n. sp., has demonstrated unequivocally that there is no justification for the resurrection of Hemipagurus. Consequently, this genus is once again relegated to the status of junior synonym of Catapagurus, and all of the species reassigned to or recently described in the genus Hemipagurus are returned to, or transferred to, Catapagurus. Catapagurus spinicarpus de Saint Laurent & McLaughlin, 2000, and C. danida McLaughlin, 2002, two species not considered in the recent revision, are compared to their closest congeners, as is the new species.

Mémoires du Muséum national d'Histoire naturelle 191:151-229, ISBN:2-85653-557-7
Résumé [+] [-]The hermit crab genus Nematopagurus, erected by A. Milne-Edwards & Bouvier (1892) for a single Atlantic species, has vastly larger reported representation in the Indo-Pacific region. However, the majority of species have been described on the basis of one or only a few specimens. The Musorstom expeditions to the south central Pacific and Philippine Islands, supplemented by the surveys of the United States Fish Commission steamer Albatross in Hawaiian, Philippine and Japanese waters, have provided not only a substantial amount of new material, but sufficient representation of most described species to permit the evaluation of intraspecific morphological variation. As a result, although five new species have been recognized, three recently described species have proven to be junior synonyms of previously known, but poorly represented, species. Nematopagurus holthuisi McLaughlin & Hogarth and N. pilosus Komai are synonymous with N. gardineri Alcock, while N. shinnyoae Komai is synonymous with N. kosiensis McLaughlin. The range of N. diadema Lewinsohn, reported previously from the Red Sea, the eastern coast of South Africa, and the South China Sea, has been extended to Fiji, while that of N. meiringae McLaughlin, known from eastern South Africa and the South and East China Seas, has been extended to the Philippine Islands. Nematopagurus kosiensis McLaughlin, previously known only from eastern South Africa has been found not only in Japanese waters, but also as far east as the Hawaiian Islands. Species identified by several authors as N. squamichelis Alcock and N. muricatus (Henderson) have been reexamined and correctly reassigned to other taxa. Descriptions and illustrations are presented for all species, together with a key for their recognition.

Similarly, the discovery of a new and readily recognizable species belonging to the heretofore monotypic Icelopagurus McLaughlin extends the distribution of this genus from Indonesia to New Caledonia. The diagnoses of both genera have been emended slightly to accommodate the interspecific variation exhibited by the taxa now included.

Résumé [+] [-]A new species of the distinctive hermit crab genus Pteropagurus McLaughlin & Rahayu, 2006, P spinulocarpus n. sp., is described and illustrated, bringing to three the number of species found to occupy empty pteropod mollusc shells. This new species is distinguished from other members of the genus by the presence of spines on the dorsal margins of the carpi of the ambulatory legs and by the absence of corneous spines on the ventral margins of the dactyls of these appendages. Additionally, a new genus and species, Dentalopagurus levii n. gen., n. sp. is described and illustrated based on three male specimens collected during explorations south of the Isle of Pines, New Caledonia. This new genus differs from other scaphopod dwelling genera and species in having well developed, paired male sexual tubes.

Because the latter species has proved to be the senior subjective synonym of T. similis Komai, 1999, the range of T. senticosa also now includes the Ogasawara Islands of Japan. A new species, Turleania boucheti n. sp., is described and illustrated from materials collected in the New Caledonia and Wallis and Futuna economic zones.

Résumé [+] [-]The larvae of two species of the pylochelid genus Trizocheles are described from prematurely hatched specimens and compared with earlier described larvae of Pylocheles (Pylocheles) and Pomatocheles. Although all are lecithotrophic and exhibit marked advanced development, differences in the larval morphology among the three genera are profound. Consideration is given to these differences as they relate to development in the entire Paguroidea, and the possible impact they may have on pylochelid phylogeny. As one of the Trizocheles species is undescribed, adults as well as larvae are described and illustrated.

Résumé [+] [-]Additional materials of two species of the recently described pagurid genus Pteropagurus McLaughlin & Rahayu, 2006 have required an emendation of the genus. These have also provided the information needed to supplement the original species descriptions, including the unusual morphology of the male of P. spina McLaughlin & Rahayu, 2006 and the sexual dimorphism and variability found in P. spinulocarpus McLaughlin, 2007. Brief data on the larval development in Pteropagurus have been gleaned from zoeae prematurely hatched from one female of P. spinulocarpus. What heretofore had been considered a unique habitat for species of this genus, i.e. empty shells of a pelagic pteropod, was found to also provide carcinoecia for Catapagurus spinicarpus de Saint Laurent & McLaughlin, 2000, a species previously known only from its female holotype collected in the Kermadec Islands of New Zealand. Th e male of this species is described and species’ variability and dimorphic attributes are assessed. Consideration is given to the question of habitat choice and the morphological adaptations required for use of the unusual carcinoecia.

The subfamilies Pylochelinae and Pomatochelinae are retained, the latter with the genera Pylocheles and Cheiroplatea; however, the subgenera Xylocheles and Bathycheles are elevated to generic rank together with the nominal subgenus Pylocheles. In addition, one new species, B. phenax, is described in Bathycheles and B. profundus is shown to be conspecific with B. integer. The subfamilies Parapylochelinae, Cancellochelinae, Trizochelinae, and Mixtopagurinae are reduced to ranks of tribes and included in the subfamily Trizochelinae. A new genus Forestocheles is proposed in the tribe Trizochelini. Within the genus Trizocheles, subspecific rank for T. spinosus bathamae is deemed unjustified and this taxon is placed in synonymy with the nominal subspecies T spinosus spinosus. The correct identity of Trizocheles balssi is established and the species mistakenly thought to represent that taxon is described as T. hoensonae, new species. Trizocheles gracilis is found to be conspecific with T. boasi and an additional new species, T. mendanai, is added to the genus. The superfamilial ranks of Cheiroplateoidea, Pomatocheloidea, Pylocheloidea, and Cancellocheloidea proposed by Watabe (2007) are rejected, as is Birgusoidea.

Résumé [+] [-]Although this paper concerns a large collection of dromiid crabs from the Philippine Islands and New Caledonia, with a few specimens from Indonesia and Hawaii, the opportunity is taken to review and revise most of the genera of the Dromiidae. The basis of the revision involves a much wider range of characters than have been used before. Excessive emphasis on the nature of the female sternal grooves is abandoned, and more attention is paid to relative dimensions and ornamentation of the carapace, arrangement of spines on and around the dactyli of all the legs, fusion of the last two segments of the abdomen, and size of the uropod plates. A new set of characters describing the second antenna and the male abdominal locking mechanism are also used. The impxDrtance of the cheliped epipod character is discussed and is shown to be variable in some genera. A total of 28 genera are defined or redefined and a key to their identification is provided, along with keys to the identification of 99 species in these genera. The following genera are restricted and/or redefined : Cryptodromia Stimpson, 1858, Cryptodromiopsis Borradaile, 1903, Dromia Weber, 1795, Dromidia Stimpson, 1858, Dromidiopsis Borradaile, 1900, Epigodromia (a replacement name for Epidromia Kossmann, 1818, which is preoccupied), Homalodromia Miers, 1884, Paradromia Balss, 1921, Petalomera Stimpson, 1858, and Pseudodromia Stimpson, 1858, resulting in the creation of 10 new genera. Ascidiophilus Richters, 1880, Conchoecetes Stimpson, 1858, Epipedodromia Andre, 1932, Eudromidia Barnard, 1947, Exodromidia Stebbing, 1905, Hemisphaerodromia Barnard, 1954, Hypoconcha Guerin-M6neville, 1854, Speodromia Barnard, 1947, and Sphaerodromia Alcock, 1899, remain unmodified. After the elimination of many synonyms and together with the new material described herein, the Dromiidae now includes 29 genera and 109 species. The generic revision has major implications for the dromiid crabs of, not only the Philippines and New Caledonia but also, the rest of the Indo-Pacific region, Australia, South Africa, and the Atlantic. Until now only six species of dromiid crabs were known from New Caledonia and the Philippine Islands. This number is increased to 29 species belonging to 13 genera. The most common species are Lauridromia intermedia (Laurie, 1906) nov. comb., Petalomera pulchra Miers, 1884, Cryptodromia coronata Stimpson, 1858, Dromidiopsis dubia Lewinsohn, 1984, and Epigodromia areolata (Ihle, 1913) nov. comb. Most of these dromiids come from shallow water, less than 100 m, and the maximum number of sp)ecies occurs in the depth interval of 30-60 m. The greatest depth of 437 m is shown by Frodromia atypica (Sakai, 1936) nov. comb. There is a large range of body size from a few millimetres, for Homalodromia coppingeri, to around 200 mm CW, for Dromia dormia. Egg size ranges from 0.4 mm to 1.1 mm diameter but there is no evidence of direct development amongst these dromiids. The apparent biogeographic affinities of the dromiids from New Caledonia and the Philippines are, in decreasing order, with Japan, Indian Ocean, Indonesia, and Australia. The apparent affinity with Japan may well be an artifact of more intensive collecting. The most wide ranging species are Lauridromia intermedia (Laurie, 1906), Dromia dormia (Linnaeus, 1763), D. wilsoni (Fulton & Grant, 1902) nov. comb., Cryptodromiopsis unidentata (Riippell, 1830) nov. comb., Cryptodromia hilgendorfi De Man, 1888, and C. fallax (Lamarck, 1818) nov. comb. These species also represent the most wide ranging genera. The collection of species largely consists of widely distributed species typical of an island fauna.

Résumé [+] [-]The Dynomenidae are a group of small, uncommon, primitive crabs, which are often associated with corals. They inhabit depths down to around 500 m, between latitudes 40°N and 40°S. All genera and species are revised and redescribed, and the genus Dynomene Desmarest, 1823 is divided into two additional genera. As a result, there are thirteen known species belonging to five genera: Dynomene Desmarest, 1823 [D. hispida Guérin-Méneville, 1832, D. praedator A. Milne Edwards, 1879, D. pugnatrix de Man, 1889, D. filholi Bouvier, 1894, and D. pilumnoides Alcock, 1900], Hirsutodynomene gen. nov. [H. spinosa (Rathbun, 1911), and H. ursula (Stimpson, li>60)], Metadynomene gen. nov. [Ai. devaneyi (Takeda, 1977), M. tanensis (Yokoya, 1933), and M. crosnieri sp. nov.], Acanlliodromia A. Milne Edwards, 1880 [A. erinacea A. Milne Edwards, 1880, and A. margarita (Alcock, 1899)], and Paradynomene Sakai, 1963 [P. tuberculata Sakai, 1963]. A key is provided to identify these species. In addition nine fossil genera, dating from the Upper Jurassic, are known: Stephanonietopon Bosquet, 1854, Dromiopsis Reuss, 1859, Palaeodromites A. Milne Edwards, 1865, Cyamocarcinus Bittner, 1883, Graptocarcinus Roemer, 1887, Cyclothyreus Remes, 1895, Gemmellarocarcinus Checchia-Rispoli, 1905, Glyptodynomene Van Straelen, 1944, Trachynotocarcinus Wright & Collins, 1972. Some extinct species have also been placed in the genus Dynomene. The definition of the family Dynomenidae given by ALCOCK (1901) is updated and expanded in order to allow fossil species to be more accurately determined. Because of overlap with the Dromiidae, there has been some uncertainty about true family affinities of some fossils. Although these genera are in need of revision, this is not undertaken in this paper. The status oi Dynomene pilumnoides is established as a valid species, D. pugnatrix brevimana Rathbun. 1911 is synonymized with D. pugnatrix de Man, 1889, D. granulobata Dai, Yang & Lan, 1981 is a synonym of D. hispida, while D. sinensis Chen, 1979, D. tenuilobata Dai, Yang & Lan, 1981, and D. huangluensis Dai, Cai & Yang, 1996 are all synonyms of D. praedator. Dynomenids are reported from Australia for the first time in D. pilumnoides, and Hirsutodynomene spinosa. The status of Metadynomene tanensis (Yokoya, 1933) is established as a widespread Pacific species and shown to be part of the fauna of Japan, where it has been confused with D. praedator. Paradynomene tuberculata, previously known from Japan and New Caledonia, is now recorded from the Gulf of Aden, Indian Ocean. P. tuberculata as well as D. praedator and H. spinosa, are reported from Guam. The Atlantic Ocean and the Indo-Pacific share genera of dynomenids but not species. The biogeographic history of dynomenids is interpreted in the liglit of tfieir present distribution and in relation to plate tectonics. Ancestral dynomenids are assumed to have been tethyan crabs and D. filholi and Acanthodromia erinacea, two insular Atlantic species, are shown to be tethyan relicts. By contrast, Hirsutodynomene ursula from the eastem Pacific, seems to be a species of quite recent origin. In redescribing the species particular attention is paid to some new characters: setae, gills, epipods and gill cleaning mechanisms, the subchelate structure of the last pereopods and the male pleopods. This work was undertaken using a scanning electron microscope. Differences in the gross appearance of setae can be used to separate species and there are substantial differences in setal structure at the microscopic level. The standard branchial formula for dynomenids is shown to be nineteen gills plus seven epipods. There is little variation in gill numbers but substantial variation in gill shape between species. Although dynomenid gills are often said to be "transitional" they are arranged as in phyllobranchs but with the epibranchial part divided into varying numbers of lobes which gives them a trichobranch-like appearance. Acanthodromia has gills which are almost identical to the phyllobranchs of the Dromiidae but which retain the "dynomenid notch" on each side which, in cross section, give each gill plate a violin shape. The gill cleaning mechanism in dynomenids is complex, being carried out by no less than eight appendages (long setae on the posterior margin of the scaphognatbite and the seven epipods) as well as stiff setae on the posterior hypobranchial wall of the gill chamber. In eubrachyurans only three appendages (maxillipodal epipods) are used. In dynomenids the last pereopod is very reduced (on average less than one-third the length of the fourth pereopod) and carried in a horizontal position alongside the posterolateral carapace margin above the base of the preceding pereopod. They are not, as it has been commonly described, carried subdorsally. Using a scanning electron microscope it was revealed that this limb is sexually dimorphic: in males the dactyl has the normal shape of a tiny claw, but in females the dactyl is a flattened plate, bearing five to sixteen spines which are opposable to an extension of the propodus. In both males and females the propodal extension is armed with spines but in Hirsutodynomene. Metadynomene and Paradynotnene, females have a significantly larger number of spines, which are armed with tiny teeth. Males of three species have an additional small spine on the outer margin of the dactyl. This is a character, previously only known amongst the Dromiidae, which suggests that the last pereopod of dynomenids may have evolved from a camouflagecarrying limb. This limb appears to be vestigial and it is difficult to know what its function may have been amongst the dynomenid ancestors. However its most likely former role appears to be as a cleaning appendage, but certainly not for carrying pieces of camouflage as it is found amongst the dromiids and homolids. All dynomenids, except Acanthodromia, lack an effective abdominal locking mechanism and both sexes have five pairs of pleopods. The female has vestigial, uniramous first pleopods followed by four pairs of normal biramous pleopods, while the male has the normal first two pairs of pleopods as well as three pairs of rudimentary pleopods on segments three to five. These rudimentary pleopods can be uniramous or bifid. In Metadynomene tatiensis 17% of females were gynandromorphs with small male first pleopods but the remaining pleopods were normal. The diet of dynomenids seems to consist of food obtained by sieving fine sediment or perhaps coral mucus. The bunches of sfiff setae on the inner margins of the cheliped fingers and third maxillipeds are probably used to separate fine organic fragments. Most of their gut contents are unidentifiable soft organic material along with small amounts of chopped chitinous fragments perhaps coming from hydroids or other crustaceans. Dynomenids appear to be deposit feeders. Dynomenids have a broadcast reproductive strategy, with indirect development, laying small eggs (mean diameter = 0.49 mm) which probably produce planktonic larvae. Dynomenid larvae have never been reported in plankton samples. Males are on average 19% larger than females which become sexually mature at 5-8 mm CW for small species, or 9-13 mm CW for large species. Egg numbers increase logarithmically with body size. Given the sister group relationship with homolodromiids (which have very abbreviated development) it is implied that dynomenids and dromiids evolved from ancestors which had large eggs and perhaps a brooding strategy. This conclusion is contrary to accepted wisdom, but it is the most parsimonious answer. Some dromiids have retained the brooding strategy but others have independently evolved a broadcast strategy. The evolution of such a strategy in both these families is probably related to their colonization of the shallow water habitat. Both dynomenids and dromiids are mostly crabs of the continental shelf whereas homolodromiids are crabs of the continental slope. Using morphological characters the phylogenetic relafionships of the Dynomenidae are examined. Both the Dynomenidae and the Dromiidae are monophylefic, sharing significant apomorphies. The resemblance of some dynomenids and dromiids is shown to be the result of convergent evolution within these families. The Homolodromiidae are also monophyletic but are defined almost exclusively by plesiomorphies. Monophyly of the Dromiacea de Haan, 1833 is supported by morphological characters with the Dynomenidae and Dromiidae together being the sister group of the Homolodromiidae. The ancestor of these three families was probably a camouflage carrying crab, using both of the last two pairs of pereopods. A controversial aspect of the sister group relationships of the dromiaceans is the need to assume that in dynomenids the fourth pereopod has reverted to a locomotory role and the fifth pereopod became a cleaning limb. Monophyly of the Podotremata Guinot, 1977 is also supported. This analysis suggests that camouflage-carrying behaviour has evolved independently in the Dromiidae (and probably in the Homolodromiidae) and the Homolidae. Dromiids carry pieces of sponges or ascidians as well as shells, using the last two pairs of pereopods, while homolids carry sponges or anemones, using only the last pair of pereopods. The ancestor of the Dromiacea and Archaeobrachyura was probably an inhabitant of deeper waters and not a camouflage carrying crab.

Mclay C.L. 2001. Dynomenidae and Dromiidae (Decapoda, Brachyura) from Guam, Philippine Islands, Tonga and Samoa. Zoosystema 23(4): 807-856
Résumé [+] [-]Five species of Dynomenidae are recorded from Guam, Mariana Islands. Two new species of Dynomene are described. Distinctive characters of D. kroppi n. sp. are: carapace width/length ratio= 1.1, six small, blunt anterolateral teeth, and five or six spines on inner margins of walking leg dactyli; and for D. guamensis n. sp. are: carapace width/length ratio = 1.3, five acute anterolateral teeth, two prominent frontal swellings, two tubercles behind postorbital corner, and seven or eight spines on inner margins of walking leg dactyli. Nine new records and one new dromiid species are reported from Guam: the distinctive characters of Cryptodromia pitiensis n.sp. are: carapace width/length ratio= 1.3, a prominent swelling above the anterolateral margin, carapace surface mostly smooth, but areolate and with scattered tubercles. Nine new dromiid records are also reported for Tonga and Samoa. Five new dromiid records are reported, based on material collected by the Albatross Expedition, 1907-1910, to the Philippine Islands. A total of 29 dynomenid and dromiid species are reported from the Mariana and Philippine Islands, of which only seven species are shared. New keys are provided to identify species of Dynomene, Sphaerodromia and Cryptodromia. Dynomenids and primitive dromiids share similar gonopod characters. Advanced dromiids have gonopods whose derived structure may be linked to the longer sternal sutures 7/8 in females. The third maxilliped crista dentata, as found in podotreme crabs, is absent from all Eubrachyura. Tooth-like maxilliped marginal tubercles in these crabs should be called the marginal dentata. Podotreme crabs show a variety of coxal and sternal abdominal locking mechanisms linked to the presence of uropods.

Mémoires du Muséum national d'Histoire naturelle 193:375-391, ISBN:2-85653-585-2
Résumé [+] [-]Seven species of retroplumid crabs are recorded from Indonesia, Philippine Islands, Solomon Islands, Fiji Islands and New Caledonia. These include Retropluma denticulata (Solomon Islands), R. notopus (Fiji), R. plumosa (Fiji), R. quadrata (Philippine Islands), R. serenei (Fiji Islands and New Caledonia), R. laurentae n. sp. (Indonesia, Philippine Islands, Solomon Islands and New Caledonia), and Bathypluma forficula (Solomon Islands and New Caledonia). The new material considerably extends the distribution of retroplumid crabs eastwards in the Pacific and also extends the depth range of several species. There are now ten extant species of retroplumids known in two genera: Bathypluma de Saint Laurent, 1989 and Retropluma Gill, 1894. Although larval development is unknown, their small egg size suggests that retroplumids have indirect development. Three fossil genera, containing eight species, are recognized: Costacopluma Collins & Morris, 1975, Retrocypoda Via Boada, 1957 and Loerenthopluma Beschin et al. 1996. Some of the fossils placed in the Retroplumidae probably belong to the Palicidae Bouvier, 1898. An analysis of recently discovered fossil retroplumids shows that this family first appeared in the Proto-Atlantic Ocean during the Late Cretaceous, but became extinct in the Atlantic by the Pliocene. The family is now only found in Indo-West Pacific seas.

Résumé [+] [-]The genus Conchoecetes Stimpson, 1858, has long been considered to include three species: C. artificiosus (Fabricius, 1798), C. andamanicus Alcock, 1900, and C. intermedius Lewinsohn, 1984. The type species, C. artificiosus, has been assumed to be widely distributed throughout the Indo-West Pacific and a fourth species, C. conchifera (Haswell, 1882), from Australia, has been regarded as a synonym. The enigmatic and long overlooked “Caphyra pectenicola Adams, in Belcher, 1848” is shown to be a species of Conchoecetes occurring in Java, Singapore and the Gulf of Thailand. We review the status of these species, establish C. conchifera as a valid species, and describe five new species: C. atlas n. sp., C avikele n. sp., C. chanty n. sp., C. investigator n. sp. and C. pembawa n. sp. In this revision we recognize 10 valid species in Conchoecetes. They are distributed from Southern Africa, across the Indian Ocean to Australia and northwards to China. Formerly considered to be cosmopolitan, C. artificiosus is restricted to India, Sri Lanka Pakistan, as well as the Persian Gulf and Madagascar, while C. intermedius, first discovered near Madagascar, is shown to be the most widespread species occurring from Africa to China.

Résumé [+] [-]The Dromiidae of Western Australia are summarized primarily based on specimens from the collection of the Western Australian Museum and some additional material from the Australian Museum, Sydney. The genus Alainodromia McLay 1998, is recorded from Camden Sound, Australia, as a new species Alainodromia dambimangari sp. nov. New evidence suggests that the species of Alainodromia are very likely shell carriers that also have direct development. Five species of Cryptodromia are reported from Western Australia and a new genus, Baccadromia gen. nov., is erected for Dromia (Cryptodromia) bullifera Alcock, 1900. The genus Lamarckdromia Guinot & Tavares, 2003 is revised and now includes three species: L. beagle sp. nov., L. excavata (Stimpson, 1858) and L. globosa (Lamarck, 1818). Six species of Dromiidae are new to Australia: Baccadromia bullifera (Alcock, 1900), Cryptodromia amboinensis (De Man, 1888), C. pileifera Alcock, 1901, Epigodromia rotunda McLay, 1993, and Foredromia rostrata McLay, 2002. New records for Western Australia include: Cryptodromia hilgendorfi De Man, 1888, Epigodromia areolata (Ihle, 1913) and Lewindromia unidentata (Rüppell, 1830). A total of 31 species of dromiid crabs are now known from Western Australian coast with five species endemic to the state. There are more than 40 species of Dromiidae known from Australia of which about 40% are endemic.

Résumé [+] [-]Relatively few studies have been done to define or assess rarity in the marine environment. Published studies have focused on shallow-water and intertidal habitats, and the available information appears to reflect the same pattern observed in terrestrial environments, i.e., that there are many rare species and few common species in any one given area. However, our studies of the abundance of new and/or supposedly rare taxa of decapod crustaceans from the deep, steep slopes of the island of Balicasag, in the central Philippines, have raised questions on how rarity should be defined in marine invertebrates. Examples of such supposedly rare species of crabs and lobsters (Crustacea: Decapoda) are presented here. That these animals come from deep, steep slopes, a relatively under-studied habitat, highlights the major gaps in current knowledge of marine biodiversity that are in part due to the inadequacy of both traditional and high technology sampling methodologies and the limited habitat types that the former can target. Low-technology, artisanal tangle nets have proved to be an optimal capture technique for deep-water decapod crustaceans on deep, steep slopes; many new taxa have been discovered and, in other cases, perceptions of rarity and endemicity have been corrected.

Résumé [+] [-]A new species of pontoniine shrimp, Periclimenes sandybrucei n. sp., is described and illustrated based on a specimen collected from deep water off northeastern Taiwan. The new species is allied to the “Periclimenes foresti Bruce, 1981” species group but can be readily distinguished from all the known species of this group by bearing three pairs of dorsolateral spines on the telson, and having the propodi of the third to fifth pereiopods unarmed.

Murphy A.E. & Williams J.D. 2013. New records of two trypetesid burrowing barnacles (Crustacea: Cirripedia: Acrothoracica: Trypetesidae) and their predation on host hermit crab eggs. Journal of the Marine Biological Association of the United Kingdom 93(01): 107-133. DOI:10.1017/S0025315412001270
Résumé [+] [-]Acrothoracican barnacles of the genus Trypetesa are obligate symbionts of hermit crabs that burrow into the gastropod shells occupied by their hosts. In the present study, hermit crabs were examined for the presence of trypetesids, based on collections from the United States, Jamaica, and the Philippines made between 1997 and 2008. Shells from Jamaica and New York contained Trypetesa lateralis, a trypetesid previously documented from central California. Trypetesa lateralis is redescribed based on light and scanning electron microscopy, showing the presence of an external mantle flap and asymmetrical opercular bars diagnostic for this species. The mean prevalence of trypetesids in Jamaica was 8.3% and most barnacles were associated with Calcinus tibicen; in New York the barnacles were found in 1.6% of shells occupied by Pagurus longicarpus. Specimens from the Philippines were identified as Trypetesa spinulosa (formerly known only from Madagascar) based on the presence of their diagnostic orificial palps. The mean prevalence of T. spinulosa in the Philippines was 3.7% and most barnacles were associated with Calcinus spp. Hermit crab eggs were observed in the guts of T. lateralis from Jamaica and T. spinulosa from the Philippines. In both of these regions the trypetesids were found significantly more often in shells occupied by female hermit crab hosts (80–87% with females). These findings suggest the barnacles be classified as transient parasites. The biology of trypetesids is reviewed and a key to the family is provided. Further studies are needed to determine if egg predation occurs in all trypetesids and the impacts on hosts.

Résumé [+] [-]An updated checklist of Mozambican marine brachyuran crabs is generated based on an exhaustive revision of the existing literature, together with the additional records provided by the specimens collected throughout the three “MOZAMBIQUE” surveys carried out in Mozambican waters during three consecutive years (2007–2009) by the Instituto Español de Oceanografía, (Spanish Institute of Oceanography, IEO). A total of 269 species, grouped in 15 superfamilies, 26 families and 172 genera are reported in the checklist, and a detailed inventory is produced with the list and remarks about the brachyuran species collected. Thirty-nine crab species belonging to 19 families were identified based on morphological characteristics and/or genetic tools. DNA barcode sequences (16S rRNA and/or COI) were obtained for 37 species, including 16S and COI sequences that are new for 26 and 14 species, respectively. Colour photographs of fresh specimens illustrate the comments about most species, being the first time that the original colour pattern is described for some of them. New records in Mozambican waters are reported for the species Paromolopsis boasi, Mursia aspera, Carcinoplax ischurodous, Tanaoa pustulosus, Euclosiana exquisita, Oxypleurodon difficilis, Naxioides robillardi, Samadinia galathea, Cyrtomaia gaillardi, Paramaja gibba, Pleistacantha ori, Parathranites granosus, Parathranites orientalis, Ovalipes iridescens and Charybdis smithii, and second records for Moloha alcocki, Samadinia pulchra and Charybdis africana. In addition, Raninoides crosnieri, S. galathea and P. ori were collected for the first time after their descriptions. The female of Samadinia galathea is described for the first time, and a potential new species of Mursia is reported. Some records expand the known bathymetric range of certain species and/or their general distribution. New molecular and morphological data suggest the necessity of the revision of P. boasi, R. crosnieri, C. africana and the genera Platymaia and Carcinoplax. The variability and taxonomic validity of some morphological characters in brachyuran systematic is discussed.

Résumé [+] [-]The present study limits the distribution of a deep-sea crab, Trichopeltarion ovale Anderson, 1896, to the Indian Ocean, and describes a new species of what has been referred to as T. ovale from the western Pacific and southeast Asia. Trichopeltarion danieleae sp. nov. differs morphologically from allied congeners by a combination of characters of the carapace and ambulatory legs. The new species is also distinguished from two fossil Trichopeltarion species, T. huziokai (Imaizumi, 1951) and T. inflatus (Kato, 1996).

Résumé [+] [-]Research on the marine anthuridean fauna of the south-western Pacific Ocean has been carried out sporadically in the Indonesian Archipel, Philippines, Fiji, Australian coasts and some Polynesian islands (Society, Cook). Stebbing's study (1900) is the only previous paper dealing specifically with the area of the Loyalty Islands, where he reported the species Apanthura sandalensis and Parantbura lifuensis. The present paper is a report on a small collection of anthuridean isopods collected in the area of New Caledonia and Loyalty Islands. Thirteen species of anthurideans, representing three families and ten genera are described (nine species are new to science): Kupellonura caudoserrata n. sp. (Fam. Hyssuridae), Haliophasma profunda n. sp., Pendanthura anophthalma n. sp., Quantanthura caledonensis n. sp. (Fam. Anthuridae), Accalathura singularia n. sp., Aenigmathura lifouensis n. sp., Bullowanthura furcillata n. sp., Leptanthura monnioti n. sp., L. segonzaci n. sp., Pseudanthura baeckea Poore & Lew Ton, Colanthura sp., Leptanthura sp. 1, Leptanthura sp. 2 (Fam. Paranthuridae). For Pendanthura, Quantanthura, Aenigmothura and Bullowan thura genera I give the identification keys made according to the morphological features, easy remarkable, thus dissections being unnecessary in every case. These keys are mainly based on the information from literature. Unfortunately many species are imperfectly described; due to this imperfect description of the species of Kupellonura, Haliophasma, AccalatAura, and Leptanthcra genera I have not presented identification keys for them. Key of the species of Pseudanthura genus has been made by Poore &Lew Ton (1986a:66).

Résumé [+] [-]The poorly known majid genus Majella Ortmann, 1893, is revised. The genus was previously known only from one species, M. brevipes Ortmann, 1893, described from Japan and reported from east Africa. Majella brevipes is redescribed and figured in detail from the type and material from the type locality, Sagami Bay in Japan. This species is now restricted to Japan. Specimens from east Africa are herein described as two new species: M. skolopion n. sp. and M. pristis n. sp.; they differ markedly from M. brevipes (now restricted to Japan) in the arrangement of spines on the carapace and pereopods, third maxillipeds, male pleon and gonopods.

Résumé [+] [-]For the century to 2018, only one species of the deep-water porter crab Gordonopsis Guinot & Richer de Forges, 1995 (Brachyura, Homolidae), the type species, G. profundorum (Alcock & Anderson, 1899), was known, and only from a handful of specimens from the Indian Ocean. In 2019, two species were described from the eastern Indian and western Pacific Oceans. The present revision of available material, most of which was only collected in the last decade, adds five new species to the genus. This explosion in species numbers demonstrates just how poor our understanding is of deep-sea habitats and their constituent fauna.

A new genus, Flaberhina, is established for C. balabacensis Serène, 1971 from the Philippines and New Caledonia. Despite their superficial similarities, the two genera can easily be separated by the structures of the carapace, eye, antenna, pterygostome, thoracic sternum, pleon and penis. The taxonomy of the subfamily Cyrtorhininae Guinot & Ng, 2020, which contains both fossil and extant taxa, is also reviewed.

Résumé [+] [-]A new species of majid crab, Sakaija amicitiae n. sp., is described from New Caledonia Exclusive Economic Zone, Vauban seamount and the Chesterfield Atolls. The species is superficially similar to S. japonica (Rathbun, 1932) and S. santo Ng & Richer de Forges, 2015, from Vanuatu. Specimens from New Caladonia previously referred to S. santo are now referred to the new species. Sakaija amicitiae n. sp. can be distinguished from congeners by features of the carapace spines, proportions of the ambulatory legs and structure of the male first gonopod.

Résumé [+] [-]The systematics of four species of the homolodromiid genus Dicranodromia A. Milne-Edwards, 1880, from East Asia and the Philippines is reappraised: D. danielae Ng & McLay, 2005, D. doederleini Ortmann, 1892, D. karubar Guinot, 1993, and D. martini Guinot, 1995; and key characters such as the epistome, gonopods, and spermatheca are figured in detail. Two new species, D. erinaceus sp. nov. and D. robusta sp. nov., are described from Taiwan and the Philippines, respectively. Dicranodromia erinaceus sp. nov. resembles D. spinulata Guinot, 1995, and D. delli Ahyong, 2008 (from New Caledonia and New Zealand) but can be separated by its distinctly spinulated carapace surfaces and proportionately shorter fifth ambulatory legs. Dicranodromia robusta sp. nov. is superficially similar to D. baffini (Alcock & Anderson, 1899) and D. karubar Guinot, 1993, but can easily be separated by possessing a broad dorsoventrally flattened infraorbital tooth. A genetic study of the species using the mitochondrial cytochrome c oxidase I gene confirms that the taxa are distinct, with D. erinaceus sp. nov. coming out in a well-supported clade from congeners. The megalopa of D. doederleini is also reported for the first time.

Résumé [+] [-]A new genus and species of xanthid crab, Cranaothus deforgesi, is described from Chesterfield Island. Cranaothus appears to be closely related to Paramedaeus, Metaxanthops, Macromedaeus, Medaeops, Neoxanthops, Glyptoxanthus and Lipaesthesius, but differs in the form and sculptures on the carapace, as well as structures of the sternum, male abdomen and male first pleopod. The larger cheliped of Cranaothus also possesses a specialized basal cutting tooth on its dactylus.

Résumé [+] [-]Randallia serenei Richer de Forges, 1983, is shown to be a distinct species and not a synonym of Tanaoa distinctus (Rathbun, 1894). Two other species currently placed in Randallia, R. granulata Miers, 1886, and R. speciosa Chen, 1989, are also transferred to Tanaoa Galil, 2003. A new genus and new species of leucosiid crab, Galilia narusei, is also described from New Caledonia. While superficially resembling species of Toru Galil, 2003, it differs markedly in its very granular carapace, rounded intestinal tubercles, short male chelipeds and ambulatory legs as well as a gently bent male first pleopod. The nomenclature of Randallia pustulilabris Alcock, 1896, is also discussed, and Ihleorandallia Stevcic, 2005, a nomen nudum, is shown to be a junior synonym of Toru.

Résumé [+] [-]A new family, Vultocinidae, is established for an unusual new genus and new species of crab ( Crustacea: Brachyura: Goneplacoidea) here described from relatively deep waters in the central Philippines and Vanuatu. Although Vultocinus anfractus, new genus, new species, superficially resembles pilumnid genera like Lophoplax and pseudoziid genera like Planopilumnus in its deeply sculptured carapace and leg surfaces, its male abdomen and gonopods appear to affiiliate it with the Goneplacidae sensu lato instead. However, its suite of many unusual characters requires the recognition of a new family for Vultocinus. Comparisons of the Vultocinidae with the Goneplacidae sensu stricto suggests that the subfamily Mathildellinae, presently regarded as a subfamily, should be recognised as a full family; and two other problematic constituent genera, Progeryon and Conleyus, are also referred to their respective families in the Goneplacoidea. The genus Paragalene is also referred to the Progeryonidae. The extent of the sterno- abdominal cavity along the thoracic sternites, structure of the posterior thoracic sternites, position of the press button of the male abdominal locking mechanism and form of the first four male abdominal segment as characters in the taxonomy of the Goneplacoidea is also discussed.

Résumé [+] [-]The inachid spider crab genus Pleisticanthoides Yokoya, 1933, is revalidated and removed from the synonymy of Pleistacantha Miers, 1879, distinguished by the absence of strong spines on the carapace (with only spinules or setae), unarmed pereiopods (with only stiff setae along margins and not spines), possession of a relatively longer, more slender ocular peduncle with a smaller cornea, slender adult male chelae, and a gently curved male first gonopod which has the distal part dorsoventrally flattened and without a subdistal process. Three species are recognised from the Indo-West Pacific region: Pleisticanthoides simplex (Rathbun, 1932) (= Pleisticanthoides nipponensis Yokoya, 1933) from Japan, P. cameroni n. sp. from the Philippines, and P. piccardorum n. sp. from Vanuatu and Papua New Guinea.

Résumé [+] [-]The systematic positions of two ocypodoid crabs, Paracleistostoma dentatum Tesch, 1918, and P. fossulum Barnard, 1955, have been uncertain because each were described from single female specimens, with Ng et al. (2008) referring them provisionally to the Dotillidae and Varunidae, respectively. Stevcic (2011) recently established two new genera, Lazarocleistostoma Stevcic, 2011, and Brankocleistostoma Stevcic, 2011, for P. dentatum Tesch, 1918, and P. fossulum Barnard, 1955, respectively. He also recognised two new families, Lazarocleistostomidae Stevcic, 2011, and Brankocleistostomidae Stevcic, 2011, for these genera. Examination of the types and fresh material of P. fossulum indicates that while both genera are valid, the families are not justified. Brankocleistostoma is a dotillid; while Lazarocleistostoma is a varunid (subfamily Gaeticinae). The tribe Gopkittisakini Stevcic, 2011 (type genus Gopkittisak Naruse & Clark, 2009), is also shown to be a junior synonym of Gaeticinae.

Milne-Edwards, 1875, from Papua New Guinea (Crustacea: Brachyura: Majoidea: Epialtidae). Zootaxa 3718(4): 357. DOI:10.11646/zootaxa.3718.4.5
Résumé [+] [-]A new genus, Samadinia n. gen., and new species, Samadinia longispina n. sp., of deep-water epialtid spider crab is described from French Polynesia and New Caledonia. The new genus is superficially similar to Rochinia A. Milne-Edwards, 1875, but can be distinguished by having the dorsal surface of the carapace covered with small, rounded granules (versus with long spines or strong tubercles), well developed hepatic and lateral branchial spines (versus relatively shorter and weaker), a prominently constricted male thoracic sternite 4 (versus relatively broader with less prominent or without median constriction) and a proportionally broader male abdomen. A new species of Rochinia, R. granulosa n. sp., is also described from Papua New Guinea. It is easily distinguished from congeners its small adult size, the presence of numerous relatively large granules on the carapace and a relatively short hepatic spine.

Zootaxa 3773(1): 1-63. DOI:10.11646/zootaxa.3773.1.1
Résumé [+] [-]The family Acidopsidae Števčić, 2005, is revised; and two subfamilies are recognised. The Acidopsinae Števčić, 2005, is characterised by the coxal male opening, a quadrate basal antennal article and vulvae arranged near the median longitudinal thoracic sternal groove. Three genera are included in the Acidopsinae: Acidops Stimpson, 1871 (with two species), Parapilumnus Kossmann, 1877 (with two species) and Crinitocinus gen. Nov. (monotypic for Pilumnus alcocki Borradaile, 1902). The Raouliinae Števčić, 2005 (= Typhlocarcinodidae Števčić, 2005; Caecopilumnidae Števčić, 2011), is characterised by its coxo-sternal male opening, a short basal antennal article which is distinctly wider than long and vulvae arranged submedially on thoracic sternite 6. Four genera are included in the Raouliinae: Raoulia Ng, 1987 (with five species, three of which are described as new), Caecopilumnus Borradaile, 1902 (with three species of which one is described as new), Typhlocarcinodes Alcock, 1900 (monotypic) and Thecaplax gen. Nov. (for one new species).

Résumé [+] [-]The taxonomy of spider crabs of the genus Maja Lamarck, 1801, is revised, and a total of 36 species in 10 genera are now recognised from the eastern Atlantic, Mediterranean and Indo-West Pacific. The present revision describes seven genera and 17 species as new. Two genera previously synonymised under Maja: Paramaya De Haan, 1837, and Paramaja Kubo, 1936, are here treated as valid taxa. The confused nomenclature of Cancer cornutus Linnaeus, 1758, is resolved, and the name replaces Maja capensis Ortmann, 1894, and Mamaia queketti Stebbing, 1908. All genera and species are diagnosed and figured, and keys are provided for their identification.

Résumé [+] [-]The family Chasmocarcinidae Serène, 1964, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of three subfamilies comprising 16 genera (including eight described as new) and 51 species (including 19 described as new). The subfamily Chasmocarciinae Serène, 1964, consists of Amboplax n. gen. with one species; Angustopelta n. gen. with four species, two of which are new; Camatopsis Alcock & Anderson, 1899, with six species, five of which are new; Chasmocarcinops Alcock, 1900, with one species; Chasmocarcinus Rathbun, 1898, with 11 species, one of which is new; Chinommatia n. gen. with five species, two of which are new; Deltopelta n. gen. with one species; Hephthopelta Alcock, 1899, with two species, one of which is new; Microtopsis Komai, Ng & Yamada, 2012, with two species, one of which is new; Notopelta n. gen. with one species; Statommatia n. gen. with five species, two of which are new; and Tenagopelta n. gen. with three species, two of which are new. The subfamily Megaesthesiinae Števčić, 2005, consists of Alainthesius n. gen. with two species, both of which are new; Megaesthesius Rathbun, 1909, with four species, one of which is new. The subfamily Trogloplacinae Guinot, 1986, consists of Australocarcinus Davie, 1988, with three species, and Trogloplax Guinot, 1986, with one species. A neotype is selected for Chasmocarcinus cylindricus Rathbun, 1901. Three nominal species were found to be junior subjective synonyms of other species: Chasmocarcinus panamensis Serène, 1964, of C. longipes Garth, 1940; Chasmocarcinus rathbuni Bouvier, 1917, of C. typicus Rathbun, 1898; and Hephthopelta superba Boone, 1927, of Deltopelta obliqua (Rathbun, 1898). Thirteen chasmocarcinid genera are exclusively found in the Indo-West Pacific region, one (Chasmocarcinus) in both the Western Atlantic and Tropical Eastern Pacific regions, and two (Deltopelta n. gen. and Amboplax n. gen.) exclusively in the Western Atlantic. Chasmocarcinids are remarkable for occurring from depths exceeding 1000 m to shallow water and completely freshwater habitats: chasmocarcinines and megaesthesiines are found from shallow to deep water marine ecosystems, whereas trogloplacines live in freshwater streams, including cave systems.

Résumé [+] [-]New material from the Marquesas Islands and other localities of French Polynesia provided 12 thalassinidean species treated in this work, five of which are new to science. There are four species ofAxiidae: Acanthaxius spinosissimus (Rathbun, 1906), Axiopsis pica Kensley, 2003, Axiopsis consobrina de Man, 1905, Calaxius sibogae (de Man, 1925); one ofStrahlaxiidae: Neaxius trondlei n. sp.; two of Thomassiniidae: Crosniera dayrati n. sp., Mictaxius salvati n. sp.; four of Callianassidae: Callianassa amboinensis de Man, 1888, Corallianassa coutierei (Nobili, 1904), Neocallichirus frouini n. sp., Cheramus sibogae (de Man, 1905); and one ofUpogebiidae: Gebiacantha albengai n. sp. Neaxius trondlei n. sp. is differentiated by article 2 of antennal peduncle with one or two upper spines, unarmed laterally; merus of pereopod 2 and 3 unarmed on lower border; telson with three well marked transverse carinae equally distant from one another. Crosniera dayrati n. sp. is differentiated by a non spike-like, triangular rostrum, non flattened eyestalks with terminal corneas, elongate telson and uropods. Mictaxius salvati n. sp. is hermaphrodite and has abdominal pleuron 1 rounded posteroventrally, approximately quadrate telson with posterior border nearly straight, uropod exopod not bilobed. Neocallichirus frouini n. sp. is characterised by major pereopod 1 merus with prominent lower expansion bearing large spines, maxilliped 3 with non quadrate propodus. Gebiacantha albengai n. sp. differs in having a rostrum nearly twice as long as wide with three infrarostral spines, single spine on anterolateral border of carapace, pereopod 1 propodus unarmed on mesial surface.

Résumé [+] [-]The genus Calliapagurops De Saint Laurent was established in 1973 for a new species, Calliapagurops charcoti, which was briefly diagnosed. The holotype and only known specimen was a damaged (probable) female, with a carapace length of 9.5 mm and missing abdomen and pereiopods 4, 5, from the Azores. Its long cylindrical eyestalks nevertheless justified its placement in a new genus. Four specimens belonging to a new species of Calliapagurops from the Philippines are described in this work. They confirm the validity of the genus and reveal its close relationship with certain genera of the subfamily Callichirinae Manning & Felder, 1991. The genus seems better placed in the latter subfamily than in the Calliapaguropinae, as proposed by Sakai (1999). This is discussed.

Résumé [+] [-]Material recently collected from the Solomon Islands include three species of Acanthaxius Sakai & de Saint Laurent, 1989, two of which are new to science: A. clevai n. sp. and A. gadaletae n. sp. and a specimen of A. polyacantha Miyake & Sakai, 1967. Two specimens from New Caledonia are assigned to A. gadaletae n. sp. The new taxa are readily differentiated from A. polyacantha by their longer rostrum and the glabrous postcervical region of carapace. A. clevai n. sp. is characterized by a slender rostrum longer than the eyestalks, with two lateral and a suborbital spine, the gastric region with a median, submedian and lateral carina, setose pereopods 1 with three and two upper spines on the propodal palm and dactylus respectively, the telson longer than broad with three teeth and one spinule on the lateral border. A. gadaletae n. sp. is similar to A. clevai n. sp. but differs by the gastric region with two submedian carinae, the pereopod 1 with four upper spines both on the propodal palm and the dactylus, the maxilliped 3 basis with a large lower distal spine ( absent in A. clevai n. sp.) and the abdominal pleura 3 - 5 with an anterior spinule ( absent in A. clevai n. sp.).

Résumé [+] [-]Squat lobsters have a worldwide distribution and are highly visible crustaceans living in a broad range of habitats. In this study, partial sequences of two mitochondrial DNA genes (16S rRNA and COI) and a nuclear gene (H3) were obtained for all but one of the known species of the shallow-water genera Sadayoshia (Munididae) and Lauriea, Macrothea and Triodonthea (Galatheidae). Lauriea siagiani appeared to be phylogenetically closer to Triodonthea and Macrothea than to other Lauriea species, suggesting the need for taxonomic re-evaluation of these taxa. All species of Sadayoshia formed a monophyletic group that would have diverged during the Paleogene (around 50 Mya). Our results support the hypothesis that the late Paleogene–Neogene transition was a period of rapid diversification for shallowwater species of both Galatheidae and Munididae in the Indo-Pacific region. This is probably related to high tectonic activity among the Eurasian, Philippine Sea, Indo-Australian and Pacific plates and corresponding changes in distribution of habitats and ocean currents during the late Paleogene. Finally, the tropical south-west Pacific province is identified as a major diversification centre for shallow-water squat lobsters, from where species dispersed to other Pacific and Indian Ocean regions.

Résumé [+] [-]Brachyuran crabs belonging to the subfamily Ethusinae Guinot, 1977, family Dorippidae MacLeay, 1838, are adapted to carry bivalve shells or other objects on their backs by using the hooked dactyli of their last two pairs of pereopods (P4 and P5), which are dorsally located and mobile. Most species inhabit deep water and are infrequently collected. The taxonomy of the 57 known Indo-West Pacific species of ethusines is revised. The subfamily consists of three genera: Ethusa Roux, 1830, with 30 species of which four are being described as new, Ethusina Smith, 1884, with 25 species of which eight are new, and Parethusa Chen, 1997, with two species of which one is new. Ethusa and Ethusina are worldwide in distribution while Parethusa is exclusive to the Indo-West Pacific region. Seven nominal species described by other authors were found to be junior subjective synonyms of other species: Ethusa major Chen, 1993, of Ethusa orientalis Miers, 1886; Ethusa makasarica Chen, 1993, of Ethusa hirsuta McArdle, 1900; Ethusa madagascariensis Chen, 1987, of Ethusa zurstrasseni Doflein, 1904; Ethusina investigatoris (Alcock, 1896) and E. alcocki Ng & Ho, 2003, of Ethusina robusta Miers, 1886; Ethusina insolita Ng & Ho, 2003, of Ethusina dilobotus Chen, 1993; and Ethusina saltator Ng & Ho, 2000, of Ethusina paralongipes Chen, 1993.

Résumé [+] [-]Transposable elements are major constituents of eukaryote genomes and have a great impact on genome structure and stability. They can contribute to the genetic diversity and evolution of organisms. Knowledge of their distribution among several genomes is an essential condition to study their dynamics and to better understand their role in species evolution. LTR-retrotransposons have been reported in many diverse eukaryote species, describing a ubiquitous distribution. Given their abundance, diversity and their extended ranges in C-values, environment and life styles, crustaceans are a great taxon to investigate the genomic component of adaptation and its possible relationships with TEs. However, crustaceans have been greatly underrepresented in transposable element studies. Using both degenerate PCR and in silico approaches, we have identified 35 Copia and 46 Gypsy families in 15 and 18 crustacean species, respectively. In particular, we characterized several full-length elements from the shrimp Rimicaris exoculata that is listed as a model organism from hydrothermal vents. Phylogenic analyses show that Copia and Gypsy retrotransposons likely present two opposite dynamics within crustaceans. The Gypsy elements appear relatively frequent and diverse whereas Copia are much more homogeneous, as 29 of them belong to the single GalEa clade, and species-or lineage-dependent. Our results also support the hypothesis of the Copia retrotransposon scarcity in metazoans compared to Gypsy elements. In such a context, the GalEa-like elements present an outstanding wide distribution among eukaryotes, from fishes to red algae, and can be even highly predominant within a large taxon, such as Malacostraca. Their distribution among crustaceans suggests a dynamics that follows a "domino days spreading'' branching process in which successive amplifications may interact positively.

New insights gained from museum collections: Deep-sea barnacles (Crustacea, Cirripedia, Thoracica) in the Muséum National d’Histoire Naturelle, Paris, collected during the Karubar expedition in 1991. Zoosystematics and Evolution 96(2): 649-698. DOI:10.3897/zse.96.55733
Résumé [+] [-]An examination of the deep-sea barnacles (Cirripedia, Thoracica) collected by the Karubar expedition to Indonesia (1991) and deposited in the Muséum National d’Histoire Naturelle, Paris, identified 40 species contained in three families of stalked and five families of acorn barnacles. Information on these species is presented, including descriptions, updated distributions and images to aid species identification. Thirty of the species, treated herein, are new records for the Indonesian Kei Islands and Tanimbar Island, which increases the total number of species recorded from Kei Islands, Aru Island and Tanimbar Island to 40. This study demonstrates the value of museum collections as a resource in biodiversity science.

Poore G.C.B. 2007. Report to COMARGE, in Workshop on Marine Squat Lobsters, Wellington, New Zealand, National Institute of Water and Atmosphere: 9 pp.
Résumé [+] [-]One of COMARGE’s objectives is to foster the development of taxonomic expertise through workshops and exchange of taxonomists. Squat lobsters are dominant, numerous and highly visible crustaceans whose abundance has stimulated considerable taxonomic research especially over the last two decades resulting in hundreds of new species being described. During the week 3−7 September 2007 ten crustacean taxonomists with varying experience with the taxonomy of squat lobsters met at the National Institute of Water and Atmosphere, Wellington, New Zealand, to further CoML objectives. Their objectives were to compile taxonomic resources (species list, bibliography, electronic keys, electronic library) to publish on the web. During the five days of the workshop each participant shared the results of their work in presented papers (abstracts below): Shane Ahyong, New Zealand - Anomuran phylogeny - the story so far Keiji Baba, Japan - The genus Uroptychus Henderson, 1888 from the Indo-Pacific Adriana Bermúdez Tobón, Colombia (with others) - Galatheidae and Chirostylidae from Colombian waters (Crustacea: Decapoda: Anomura) Patricia Cabezas, Spain - Application of molecular tools for the study of the taxonomy and systematic of the family Galatheidae Chiawei Lin, Taiwan - Galatheoids in Taiwan seas Enrique Macpherson, Spain - Taxonomic status of the species of Munidopsis and Munida and allied genera - geographic scope and main gaps : Martha S. Nizinski, USA - State of knowledge of galatheoid taxonomy, diversity, and ecology in the western North Atlantic : Gary C. B. Poore, Australia - Australian squat lobsters: taxonomic history and prospects : Celso Rodrigues, Brazil - The family Galatheidae (Crustacea: Decapoda: Anomura) on the Brazilian coast Kareen Schnabel, New Zealand (with Keith Probert, Niel Bruce) - Deep-sea downunder, species richness, habitat and distributional patterns of New Zealand squat lobsters (Chirostylidae, Anomura, Crustacea) But most of the work during the week was devoted to compiling resources to share with future workers through the web. • A hierarchical list of the world’s species, almost 900 species was completed by building on a database compiled over recent years by Baba and Macpherson. The list with synonymies and distribution information will be completed and submitted for publication by November 2007. With a little more work the list will be suitable to upload to marinespecies.org. • A bibliography of 879 citations in Endnote X format was completed and pdfs (at least of the parts dealing with squat lobsters) of 82% of these were linked to the bibliography. It is planned to submit these to the AToL: Decapoda website. • The workshop was able to update dicotomous keys to species for most of the world’s almost 40 genera. Good progress was also made on translating some of these to interactive keys in DELTA format. This objective requires considerable more work but a promising start was made to electronic keys to families, all genera, and to species of smaller genera. Participants in the workshop are optimistic that these can be completed within a year and published in various media. • Finally, the workshop provided an opportunity for those using molecular tools for taxonomic and phylogenetic research questions to compare successes and failures.

Poore G.C.B. & Andreakis N. 2012. The Agononida incerta species complex unravelled (Crustacea: Decapoda: Anomura: Munididae). Zootaxa 3492: 1-29
Résumé [+] [-]Squat lobsters from Australia, east Africa, Taiwan, Philippines and the Norfolk Ridge (southwestern Pacific) previously identified as Agononida incerta (Henderson, 1888) are redescribed as four new species in addition to the original: A. africerta, A. auscerta, A. indocerta and A. norfocerta. A. rubrizonata Macpherson & Baba, 2009, also earlier confused with this species, is redescribed. All six species are morphologically distinguishable only on the basis of the shape of the anterolateral lobe of the telson and the shape and setation of the dactyli of pereopods 2-4. The morphological delineation of these species and their taxonomic status are robustly supported by phylogenetic analysis of the partial mitochondrial COI marker. Taken together, subtle morphological differences, geographical distribution patterns and genetic discontinuities have important implications for understanding diversity, systematics and evolution of squat lobsters.

Résumé [+] [-]Squat lobsters from Madagascar, Vanuatu, Papua New Guinea, Fiji, eastern Australia and French Polynesia belonging to the Agononida incerta (Henderson, 1888) species complex are described as four new species: A. madagascerta, A. polycerta, A. tasmancerta and A. vanuacerta. This brings to ten the number of species in this complex. All species are morphologically distinguishable only on the basis of the shape of the anterolateral margin of the telson and setation of the dactyli of pereopods 2–4. The morphological delineation of nine of the species and their taxonomic status are robustly supported by phylogenetic analysis of the partial 16S rDNA gene and the partial mitochondrial cytochrome oxidase subunit 1 genes, and in some cases by colour. A phylogenetic analysis of the nine species for which molecular data are available grouped the species in two clades, one of four species with facial spines on the upper surface of pereopod 4 and the other of five species lacking facial spines.

Résumé [+] [-]The synonymy of Axius (Neaxius) gundlachi var. orientalis De Man, 1925, with Axius (Neaxius?) euryrhynchus De Man, 1905, now Neaxiopsis euryrhynchus (De Man, 1905), is confirmed. The synonymy of Axia acantha (A. Milne Edwards, 1879), Eiconaxius taliliensis Borradaile, 1900, and Axius acanthus mauritianus Bouvier, 1914, is confirmed; they are a single species, Neaxius acanthus. They and a second species from the Indo-West Pacific, Neaxius trondlei Ngoc-Ho, 2005, are not synonyms of Neaxius glyptocercus (von Martens, 1868), as was proposed in Sakai’s (2011) family synthesis. Instead, a second species (from southern Queensland, Australia, Fiji and French Polynesia) close to Neaxius glyptocercus from north-eastern Australia is diagnosed as Neaxius capricornicus sp. nov.

Résumé [+] [-]The tropical to subtropical squat lobster Uroptychus naso Van Dam, 1933 (Chirostylidae) is a widely distributed species originally described from Indonesia, subsequently reported from the Philippines, Taiwan, Japan and it has recently been discovered on the continental slope of north-western Australia. Populations of U. naso occur along the Indo-Pacific Ocean continental margin crossing the recently proposed marine analog of Wallace's line, responsible for past population fragmentation and ancient speciation. Sequence data from mitochondrial (COI, 16S) and nuclear (H3) DNA regions were used to assess genealogical relationships among geographically disjoint populations of the species throughout its known distribution range. Several mitochondrial lineages, corresponding to geographically isolated populations and three cryptic species were encountered, namely, U. naso sensu stricto and two new species. Uroptychus cyrano and Uroptychus pinocchio spp. nov. U. pinocchio is encountered only in Japan, Taiwan and the Philippines; U. cyrano is confined to north-western Australia; and U. naso consists of three genetically distinct populations distributed on both sides of the marine Wallace's line. Fossil-calibrated divergence time approximations indicated a most recent common ancestor (MRCA) for U. naso and U. cyrano from early Eocene whilst northern and southern populations of the former have been separated probably since the Miocene. These patterns may represent a standard distribution trend for several other deep-sea invertebrate species with similar geographical ranges. (C) 2011 Elsevier Inc. All rights reserved.

Résumé [+] [-]The present paper reports on the collections of hermit crabs of the genus Ciliopagurus from French Polynesia, most of which were collected during the MUSORSTOM 9 cruise in the Marquesas Islands between August and September 1997. These include Ciliopagurus vakovako, new species, C. strigatus (Herbst, 1804), and C. krempfi (Forest, 1952). In its gross morphology C. vakovako is most similar to C. strigatus, widespread in the Indo-West Pacific, and C. tricolor Forest, 1995, restricted to the western Indian Ocean, a species formerly confused with C. strigatus. In its coloration. C. vakovako is closest to C. liui Forest, 1995, known from the Gulf of Tonkin (Vietnam) and southern Japan, and to C. krempfi, common in the Indo-West Pacific. Affinities among these species are discussed.

Résumé [+] [-]Knowledge of morphology, coloration, and distribution of species of Calcinus Dana, 1851 from French Polynesia is expanded based primarily on collections obtained during the French BENTHAUS Expedition in 2002 to the Austral Islands, the southernmost of the French Polynesian islands. Six species of Calcinus were obtained from inshore to depths of 280 m. Of these, one proved to be a new species, C. albengai, and is fully described. This new species has two colour variants, one with pale pink to cream chelipeds that lives in shallow-water from the intertidal to about 50 m, the other with bright orange chelipeds, from deeper waters from about 50 to 280 m. Morphologically this new species is distinguished by differences in the armature of the ocular acicles, aspects of the left and right palms, ventrodistal pilosity of third pereopods, and telson armature. Five species were collected by dredging, trawling, or using traps, in depths of 40 to 280 m: C. anani Poupin & McLaughlin, 1998, C. gouti Poupin, 1997, C. haigae Wooster, 1984, C. spicatus Forest, 1951, and C. aff. sirius Morgan, 1991. Of these, C. gouti was previously known exclusively based on the holotype from Tuamotu, and a more complete diagnosis is presented; the others are also diagnosed, including new details on coloration. Inshore and scuba collecting on Rapa Island produced four additional, but better known species: C. elegans (H. Milne Edwards, 1836), C. latens (Randall, 1840), C. laevimanus (Randall, 1840), and C. vachoni Forest, 1958. The inshore Calcinus fauna of Rapa is briefly compared with its counterpart on Easter Island, located at the same latitude 3500 km to the east. A total of 19 (or possibly 20, should C. sirius be confirmed in the future) Calcinus species are now known from French Polynesia. Cases of sibling species of Calcinus, distinguished almost exclusively by coloration, are summarized.

Résumé [+] [-]Four hermit crabs of the genus Ciliopagurus are recognized as a complex of species named the "strigatus complex". They are found in the low intertidal or shallow waters of the Indo-West Pacific. Ciliopagurus strigatus (Herbst, 1804) is characterized by striped legs and chelae with alternate yellow and red transverse colour bands. It is commonly found on reef habitats and is reported from the Red Sea to French Polynesia. Ciliopagurus tricolor Forest, 1995 is reported with certainty front East Africa to Reunion Island, C. vakovako Poupin, 2001 is endemic to the Marquesas Islands, and C. galzini n. sp. is described as a new species from specimens collected in the Tuamotus. Within the 17 extant species of the genus Ciliopagurus, these four species are distinct by the aspect of the ocular acicle with 3-5 terminal spines instead Of usually I or 2 in the other species, a few morphometric characters, and by their vertical distribution, from intertidal to about 20 m, whereas all the other species are usually collected deeper. The species of the "strigatus complex" are morphologically very similar and can be separated with confidence only by their coloration. All of them have similar colour patterns of transverse bands on the chelipeds and walking legs, but each species can be easily recognized by the distinct colour and/or disposition of these bands. The appraisal of these colour differences as valuable specific indicators is confirmed by phylogenetic analysis of mitochondrial and nuclear DNA sequences.

Résumé [+] [-]A compilation of species of decapod crustaceans and stomatopods from tropical French overseas territories is made from databases available for Mayotte, Reunion, New Caledonia, Wallis & Futuna, French Polynesia and Clipperton. The resulting inventory encompass about 200 years of taxonomic research, between 1829 and October 2010. The names of the species and the supra-specific classification were updated with the latest systematic revisions. 2514 valid species are reported, 2397 decapods and 117 stomatopods. The number of species per region is as follows: Mayotte, 473 species; Réunion, 496 species, New Caledonia, 1662 species, Wallis & Futuna, 277 species; French Polynesia, 1004 species, Clipperton, 95 species. The data were formatted in a spreadsheet to be easily integrated to TAXREF base of the Service du Patrimoine Naturel, Paris (http://www.mnhn.fr/spn/). They must be posted on the website for the French Inventaire du Patrimoine naturel (http://inpn.mnhn.fr/)."

Poupin J., Corbari L., Pérez T. & Chevaldonné P. 2012. Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda). Zootaxa 3550: 43-60
Résumé [+] [-]Decapod crustaceans were studied in the Marquesas Islands, French Polynesia, between 50-550 m by using a remotely operated vehicle (ROV) equipped with high resolution cameras and an articulated arm. Careful examination of videos and photographs combined with previous inventories made in the area with conventional gears allowed the identification of 30 species, including 20 species-level determinations. Species identified belong to shrimps (Penaeoidea, Stenopodidea, and Caridea), lobsters (Astacidea and Achelata), anomurans (Galatheoidea and Paguroidea), and brachyuran crabs (Dromioidea, Homolodromioidea, Raninoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, and Trapezioidea). Most of these species were observed and photographed in situ for the first time. A discussion is given on the geographic distribution, density, ecology, and behavior.

Résumé [+] [-]A preliminary assessment of the deep-sea Decapoda is proposed for Guadeloupe Island based solely on high definition macro photographs taken during the KARUBENTHOS 2015 Expedition to the Island (R/V Antea, 7–29 June 2015). Overall, 190 species are recognized, several of which are depicted with their fresh color for the first time. Previous records in the Lesser Antilles are documented and the geographic distribution of the species in these Islands is given. The historical contribution of the steamer Blake (1878–1879) in the Lesser Antilles is emphasized. All species inventoried during KARUBENTHOS 2015 were already reported in the western Atlantic but 34 of them are new records for the Lesser Antilles and 116 are reported for the first time from Guadeloupe Island. This preliminary inventory is estimated to include about 38% of the deep-sea Decapoda potentially occurring around Guadeloupe Island.

Résumé [+] [-]A collection of crabs assembled during the KUW 2009 expedition to Mayotte Island and deposited in the Muséum national d’Histoire naturelle Paris is studied. In total 202 species are recognized, 138 of them being new records for the Island and a list of brachyuran crabs is documented and illustrated with photographs. A complementary list of all crabs previously in taxonomic literature from Mayotte and its nearest Islands (Comoros Islands, Glorieuses Islands and marine banks of Zélée, Geyser and Leven) is also provided. In total 298 crabs are identified from the region, the richness of this fauna is discussed with zoogeographic considerations and the prospects for further studies are outlined.

Résumé [+] [-]A new hermit crab of the genus Calcinus Dana, 1851 is described from a specimen collected at a depth of 100 m near Rapa Island, Austral Islands, French Polynesia. In a previous report, we had reported this specimen provisionally as Calcinus aff. sirius, pending availability of live color data for Calcinus sirius Morgan, 1991. Recently obtained color photographs of live C. sirius from the Solitary Islands, Eastern Australia, has shown that the specimen from Rapa Island is distinct from Morgan’s taxon and represents a new species which is fully illustrated and described herein as Calcinus shawi sp. nov. The morphology and coloration of this new species are compared with the closely allied C. sirius and Calcinus dapsiles Morgan, 1989.

Résumé [+] [-]Des plongées techniques (TEK) en recycleur et mélanges gazeux spéciaux ont été réalisées autour de l’île de Mayotte sur les pentes externes récifales à des profondeurs comprises entre 50 et 120 m, et plus particulièrement aux alentours de 70-80 m, de 2017 à 2020. L’objectif de ces plongées était de réaliser un premier inventaire faunistique de la zone mésophotique, difficile d’accès et encore mal connue. Ce travail présente les résultats obtenus pour le groupe des Crustacés Décapodes et Stomatopodes avec au total 44 espèces photographiées en haute définition, dont 30 déterminées avec confiance, sept avec doute et sept identifiées provisoirement, peut-être nouvelles pour la nomenclature taxonomique. Les crevettes carides (16 espèces), les anomoures (15 espèces) et les crabes (sept espèces) sont les trois taxons les mieux représentés. Les stomatopodes, crevettes sténopides, langoustines et langoustes comptent chacun deux espèces. Ces observations permettent d’ajouter 32 nouvelles espèces à la faune mahoraise, dont quatre signalements nouveaux pour l’océan Indien. Les espèces sont présentées dans une liste illustrée avec une sélection de photographies. La liste est documentée avec indication des travaux ou guides consultés, des commentaires sur les déterminations et la mise à jour des distributions géographiques et bathymétriques. Pour 15 espèces traditionnellement observées sur des petits fonds (< 50 m), la profondeur maximale est augmentée entre 3 et 45 m. Plus de la moitié des espèces sont des formes libres (26 espèces). Les autres vivent en association avec les coraux ou hydraires (12 espèces), échinodermes (trois espèces), poissons (deux espèces) et éponges (une espèce). Quelques espèces sont à tendance cavernicole, observées dans des grottes ou sous des surplombs. À partir des données d’inventaire des Crustacés Décapodes de l’outre-mer tropical français, 212 espèces sont identifiées comme potentiellement présentes dans la zone mésophotique de Mayotte. Le présent inventaire de 44 espèces est donc assez modeste mais les photographies réalisées in situ permettent de mettre en évidence certaines associations ou modes de vie qui n’étaient pas soupçonnés avec les moyens d’étude classiques. À l’avenir, les observations pourront être améliorées en accordant plus d’importance aux coquilles, parfois occupées par des Bernard l’ermite non déterminés car photographiés de trop loin, et/ou en effectuant des plongées de nuit, lorsque les Crustacés sont plus actifs. La poursuite de ce programme de recherche prévoit la récolte de quelques spécimens, en particulier pour les espèces reconnues comme probablement nouvelles pour la nomenclature taxonomique.

Résumé [+] [-]The primary purpose of DNA-barcoding projects is to generate an efficient expertise and identification tool. This is an important challenge to the taxonomy of the 21st century, as the demand increases and the expert capacity does not. However, identifying specimens using DNA-barcodes requires a preliminary analysis to relate molecular clusters to available scientific names. Through a case study of the genus Eumunida (Decapoda : Eumunididae), we illustrate how naming molecule-based units, and thus providing an accurate DNA-based identification tool, is facilitated by sequencing type specimens. Using both morphological and unlinked molecular markers (COI and 28S genes), we analysed 230 specimens from 12 geographic areas, covering two-thirds of the known diversity of the genus, including type specimens of 13 species. Most hypotheses of species delimitation are validated, as they correspond to molecular units linked to only one taxonomic name (and vice versa). However, a putative cryptic species is also revealed and three entities previously named as distinct species may in fact belong to a single one, and thus need to be synonymised. Our analyses, which integrate the current naming rules, enhance the a-taxonomy of the genus and provide an effective identification tool based on DNA-barcodes. They illustrate the ability of DNA-barcodes, especially when type specimens are included, to pinpoint where a taxonomic revision is needed.

Résumé [+] [-]Seven species of Paguristes were collected in Indonesian waters during the expeditions of the Siboga (1899), the Danish Expedition to the Kei Island (1922), Th. Mortensen’s Expeditions (1899-1930), CORINDON (1980), Snellius II (1984) and KARUBAR (1991). Three species: P. arostratus, P. brachyrostris and P. antennarius were new to science. Three of four described species were previously unrecorded from Indonesia: P. palythophilus Ortmann, 1892, known only from the northwestern Pacific, was found to be common in Indonesian waters; P. aciculus Grant, 1905, previously known from Australia, was represented by two males and one intact female specimens, therefore female morphological characters could be completed; and P. pusillus Henderson, 1896 was found in deeper waters than previously reported. The fourth species was P. puniceus Henderson, 1896.

Résumé [+] [-]A new species of marine hermit crabs, Dan/anus ho/thuisi sp. nov., is described from New Caledonia and Vanuatu. This is one of the few species of Dardanus that live at depths of more than 100 m. This new species resembles D. gemmatus (H. Milne Edwards, 1848) and D. impressus Haan, 1849), but is easily distinguished from those two species by larger spiniform tubercles on the chelipeds, longer and more slender dactyl of the second and third pereopods, shorter ocular peduncles, and red colour on the fixed finger and the dactyl chelipeds, and the dactyl of the second and third pereopods which persist for several years in fixative.

Résumé [+] [-]The hexapodid genera Hexapus De Haan, 1833, Hexapinus Manning & Holthuis, 1981, Latohexapus Huang, Hsueh & Ng, 2002, and Hexaplax Doflein, 1904, are revised and redescribed on the basis of their respective type species. Hexapus s. str. is redefined and a new species is described from Indonesia. Hexapinus is restricted for H. latipes (De Haan, 1835), H. edwardsi (Serène & Soh, 1976) and three new species from Indonesia, Philippines, China and Japan. A new genus, Mariaplax, is established for Lambdophallus anfractus Rathbun, 1909, Hexapus granuliferus Campbell & Stephenson, 1970, and 11 new species from the China, Japan, Vietnam, Philippines, Indonesia, Singapore, New Guinea and Australia. A new genus, Rayapinus, is recognised for an unusual new species from Japan. Two new species of Hexaplax from Papua New Guinea, Philippines, Taiwan, and Japan are described. A new genus, Theoxapus, is also established for the east Atlantic Hexapus buchanani Monod, 1956, which had previously been placed in Hexapinus. A revised key to the genera of Hexapodidae is presented.

Résumé [+] [-]The deep-water spider crabs of the genus Cyrtomaia are very characteristic because of their globose carapaces, their long and spinose pereiopods, and because a few species can grow very large. Twenty-nine species are known at present of this Indo-West Pacific genus (Ng et al., 2008; Richer de Forges & Ng, 2008). Only three species have been reported from Taiwan until now: Cyrtomaia curviceros Bouvier, 1915, C. horrida Rathbun, 1916, and C. murrayi Miers, 1886 (cf. Ng & Huang, 1997; Ng et al., 2001; Ho et al., 2004). Cyrtomaia curviceros Bouvier, 1915, is currently regarded a junior subjective synonym of C. suhmii Miers, 1886 (cf. Guinot & Richer de Forges, 1986; Ng et al., 2008).

Résumé [+] [-]Recently collected specimens from the deep sea off Papua New Guinea revealed the presence of a new species of Oxypleurodon Miers, 1886 (Majoidea). The new species is a member of the O. auritum group but its flattened rostral spines and the triangular shape of the carapace easily distinguishes it from congeners.

Résumé [+] [-]The study of a small collection of deep-water majoid crabs of the family Epialtidae brings some new data on the geographic distribution of species in the genus Rochinia A. Milne-Edwards, 1875 (R. pulchra (Miers, 1886), R. fultoni (Grant, 1905), R. aff. brevirostris (Doflein, 1904), R. aff. soela Griffin & Tranter, 1986, R. kotakae Takeda, 2001) and Naxioides taurus (Pocock, 1890). One new species, Rochinia boucheti n. sp., is described which differs from all congeners by the presence of numerous small tubercles on the carapace and its relatively short rostral spines. Males of R. kotakae are described for the first time.

Résumé [+] [-]The inachid spider crab genus, Parapleisticantha Yokoya, 1933 [type species: Parapleisticantha japonica Yokoya, 1933] is removed from the synonymy of Pleistacantha Miers, 1879 [type species: Pleistacantha sanctijohannis Miers, 1879], and recognised as a valid genus. Parapleisticantha differs from Pleistacantha sensu stricto primarily by having a less spiny carapace, stouter and more inflated male chelipeds, and by lacking a slender subdistal process on the male first gonopod. We redescribe Parapleisticantha japonica based on the Japanese type material and describe as new a second species, Parapleisticantha ludivinae n. sp., recently discovered in the Philippines.

Résumé [+] [-]Eight species of deep-water porter crabs of the family Homolidae are recorded from Papua New Guinea from three MNHN-led cruises to these waters: Homola orientalis Henderson, 1888, Homola coriolisi Guinot & Richer de Forges, 1995, Homolomannia sibogae Ihle, 1912, Homolomannia occlusa Guinot & Richer de Forges, 1981, Paromolopsis boasi Wood-Mason in Wood-Mason & Alcock, 1891, Lamoha woodmasoni n. sp., Ihlopsis multispinosa (Ihle, 1912) and Latreillopsis gracilipes Guinot & Richer de Forges, 1981. Most are new records for the country, Lamoha woodmasoni n. sp. appears to be the Pacific sister species of the Indian Ocean L. longipes (Alcock & Anderson, 1899). The old records of the latter species from the Solomon Islands are now referred to the new species. The taxonomy of the other species is also discussed.

Robles R., Dworschak P.C., Felder D.L., Poore G.C.B. & Mantelatto F.L. 2020. A molecular phylogeny of Callianassidae and related families (Crustacea : Decapoda : Axiidea) with morphological support. Invertebrate Systematics 34(2): 113. DOI:10.1071/IS19021
Résumé [+] [-]The axiidean families Callianassidae and Ctenochelidae, sometimes treated together as Callianassoidea, are shown to represent a monophyletic taxon. It comprises 265 accepted species in 74 genera, twice this number of species if fossil taxa are included. The higher taxonomy of the group has proved difficult and fluid. In a molecular phylogenetic approach, we inferred evolutionary relationships from a maximum-likelihood (ML) and Bayesian analysis of four genes, mitochondrial 16S rRNA and 12S rRNA along with nuclear histone H3 and 18S rRNA. Our sample consisted of 298 specimens representing 123 species plus two species each of Axiidae and Callianideidae serving as outgroups. This number represented about half of all known species, but included 26 species undescribed or not confidently identified, 9% of all known. In a parallel morphological approach, the published descriptions of all species were examined and detailed observations made on about two-thirds of the known fauna in museum collections. A DELTA (Description Language for Taxonomy), database of 135 characters was made for 195 putative species, 18 of which were undescribed. A PAUP analysis found small clades coincident with the terminal clades found in the molecular treatment. Bayesian analysis of a totalevidence dataset combined elements of both molecular and morphological analyses. Clades were interpreted as seven families and 53 genera. Seventeen new genera are required to reflect the molecular and morphological phylograms. Relationships between the families and genera inferred from the two analyses differed between the two strategies in spite of retrospective searches for morphological features supporting intermediate clades. The family Ctenochelidae was recovered in both analyses but the monophyly of Paragourretia was not supported by molecular data. The hitherto well recognised family Eucalliacidae was found to be polyphyletic in the molecular analysis, but the family and its genera were well defined by morphological synapomorphies. The phylogram for Callianassidae suggested the isolation of several species from the genera to which they had traditionally been assigned and necessitated 12 new generic names. The same was true for Callichiridae, with stronger ML than Bayesian support, and five new genera are proposed. Morphological data did not reliably reflect generic relationships inferred from the molecular analysis though they did diagnose terminal taxa treated as genera. We conclude that discrepancies between molecular and morphological analyses are due at least in part to missing sequences for key species, but no less to our inability to recognise unambiguously informative morphological synapomorphies. The ML analysis revealed the presence of at least 10 complexes wherein 2–4 cryptic species masquerade under single species names.

Résumé [+] [-]The genus Munidopsis is one of the most diverse genera within squat lobsters. Here, three new species of Munidopsis, M. cornuata n. sp., M. senticosa n. sp., and M. turgida n. sp., from <500 m off Guadeloupe Island (Caribbean Sea), are fully described and illustrated. Among the Atlantic species of the genus, M. cornuata n. sp. belongs to the group of species having the dorsal surface of the carapace with spines and is most similar to M. robusta (A. Milne-Edwards, 1880), from the Gulf of Mexico and Caribbean Sea. Munidopsis senticosa n. sp. resembles M. barbarae (Boone, 1927) from the Bahamas and the Gulf of Mexico and M. penescabra Pequegnat & Williams 1995, from off Georgia and Gulf of Mexico; the three species belong to the group having the carapace covered with sharp spines. Finally, M. turgida n. sp. is characterized by having the dorsal surface of the carapace, abdomen and pereiopods covered by granules; and resembles M. granulens Mayo, 1972, from NW Caribbean Sea. Apart from the morphological evidence, the analysis of mitochondrial genes (COI and 16S) supports establishing these new species, showing very high genetic divergences compared to their congeners (from 14.5 to 17% for COI, and 7.7 to 12.8% for 16S data).

Résumé [+] [-]Abstract During two deep-sea expeditions off the island of Guadeloupe, French West Indies, several specimens belonging to MunidaLeach, 1820 and MunidopsisWhiteaves, 1874 (Galatheoidea) were collected. Further study, integrating morphological and molecular data, indicated that some of the specimens belonged to three undescribed species, one to Munida and two to Munidopsis. Munida anteaen. sp. is morphologically closely related to the Atlantic species M. microphthalma A. Milne-Edwards, 1880. Both species can be easily distinguished morphologically and represent independent evolutionary lineages. The closest relative to Munidopsis balconin. sp. is M. glabraPequegnat & Williams, 1995 from the Gulf of Mexico. They can be distinguished by the armature of the carapace and pereiopods, among other differences. Munidopsis pholidotan. sp. is sister to M. squamosa (A. Milne-Edwards, 1880) and both are considered cryptic species, distinguished only by molecular characters and subtle morphological differences like the number of epipodites. Our phylogenetic results show some monophyletic groups within Munidopsis and Munida, and the existence of morphological convergences.

Rodríguez-flores P.C., Macpherson E. & Machordom A. 2019. Revision of the squat lobsters of the genus Leiogalathea Baba, 1969 (Crustacea, Decapoda, Munidopsidae) with the description of 15 new species. Zootaxa 4560(2): 201-256. DOI:10.11646/zootaxa.4560.2.1
Résumé [+] [-]The genus Leiogalathea Baba, 1969 currently contains only two benthic species both occurring on the continental shelves and slope: L. laevirostris (Balss, 1913), widely reported in the Indo-Pacific region, and L. agassizii (A. Milne Edwards, 1880), from both sides of the Central Atlantic. A certain degree of morphological variability linked to their geographic distributions was previously noticed, mostly in L. laevirostris. In the present study, we revise numerous specimens collected from the Atlantic, Indian and Pacific Oceans, analysing morphological and molecular characters (COI and 16S rRNA). We found 15 new species; all of them are distinguished from L. laevirostris and L. agassizii by subtle but constant morphological differences and show clear genetic separation. Furthermore, L. imperialis (Miyake & Baba, 1967), previously synonymized with L. laevirostris, was found to be a valid species. All species are described and illustrated. Species of the genus Leiogalathea are morphologically distinguishable on the basis of the spinulation of the carapace, the shape and the armature of the rostrum, the shape of the propodi of the walking legs, and the pattern of the setae covering on rostrum, carapace and chelae. Some species are barely discernible on the basis of these characters but are highly divergent genetically.

Résumé [+] [-]The taxonomy of Munida Leach, 1820 from the north-eastern Atlantic and Mediterranean Sea was studied using a comparative analysis of morphological characters and molecular markers (mitochondrial and nuclear). Generalized Mixed Yule Coalescence and the Poisson tree process models were used to delimit two groups of closely related species associated with uncertain nomenclature and taxonomic status: (1) Munida intermedia A. Milne Edwards & Bouvier, 1899, M. rugosa (Fabricius, 1775), M. sarsi Huus, 1935 and M. tenuimana Sars, 1872 and (2) M. rutllanti Zariquiey-Álvarez, 1952 and M. speciosa von Martens, 1878. We found that M. tenuimana is restricted to northern Atlantic waters (north of approx. 48° N), while Mediterranean and Bay of Biscay specimens previously assigned to this taxon actually belong to a different species, indicating that the name Munida perarmata A. Milne Edwards & Bouvier, 1894 should be resurrected. Furthermore, M. rutllanti is shown to be a junior synonym of M. speciosa, a species that has thus far only been reported along western Africa. In addition, three species are re-described and a key to European Munida is provided. The validity of the morphological characters used to distinguish the different species is discussed. Phylogenetic analyses revealed three independent lineages with unsolved relationships among them, including high genetic distances for some species. These findings indicate highly divergent lineages of the European Munida and several events of colonization along the eastern Atlantic.

Résumé [+] [-]The genus Phylladiorhynchus Baba, 1969 currently contains 11 species, all occurring in the shallow waters and on the continental shelf of the Indian and Pacific oceans. Recent expeditions in these oceans have resulted in the collection of numerous new specimens in need of analysis. We have studied this material using an integrative approach analysing both morphological and molecular (COI and 16S) characters. We describe 41 new species and resurrect three old names: P. integrus (Benedict, 1902) and P. lenzi (Rathbun, 1907), previously synonymized with P. pusillus (Henderson, 1885), and P. serrirostris (Melin, 1939), previously synonymized with P. integrirostris (Dana, 1852). Most species of the genus are described and illustrated. Some species are barely discernible on the basis of morphological characters but are highly divergent genetically. Species of Phylladiorhynchus are mainly distinguishable by the number of epigastric spines and lateral spines of the carapace, the shape and the armature of the rostrum, the number and pattern of the ridges on the carapace and pleon, the shape of thoracic sternite 3 and the armature of the P2–4 dactyli. A dichotomous identification key to all species is provided.

Résumé [+] [-]The ecology, abundance and diversity of galatheoid squat lobsters make them an ideal group to study deep-sea diversification processes. Here, we reconstructed the evolutionary and biogeographic history of Leiogalathea, a genus of circum-tropical deep-sea squat lobsters, in order to compare patterns and processes that have affected shallow-water and deep-sea squat lobster species. We first built a multilocus phylogeny and a calibrated species tree with a relaxed clock using StarBEAST2 to reconstruct evolutionary relationships and divergence times among Leiogalathea species. We used BioGeoBEARS and a DEC model, implemented in RevBayes, to reconstruct ancestral distribution ranges and the biogeographic history of the genus. Our results showed that Leiogalathea is monophyletic and comprises four main lineages; morphological homogeneity is common within and between clades, except in one; the reconstructed ancestral range of the genus is in the Atlantic and Indian oceans (Tethys). They also revealed the divergence of the Atlantic species around 25 million years ago (Ma), intense cladogenesis 15–25 Ma and low levels of speciation over the last 5 million years (Myr). The four Leiogalathea lineages showed similar patterns of speciation: allopatric speciation followed by range expansion and subsequent stasis. Leiogalathea started diversifying during the Oligocene, likely in the Tethyan. The Atlantic lineage then split from its Indo-Pacific sister group due to vicariance driven by closure of the Tethys Seaway. The Atlantic lineage is less speciose compared with the Indo-Pacific lineages, with the Tropical Southwestern Pacific being the current centre of diversity. Leiogalathea diversification coincided with cladogenetic peaks in shallow-water genera, indicating that historical biogeographic events similarly shaped the diversification and distribution of both deep-sea and shallow-water squat lobsters.

Squat lobster assemblages on seamounts differ from some, but not all, deep-sea habitats of comparable depth: Squat lobster assemblages of deep-sea habits. Marine Ecology 31: 63-83. DOI:10.1111/j.1439-0485.2010.00374.x
Résumé [+] [-]This study was carried out to test the hypothesis that benthic communities on seamounts are distinct from those of other deep-sea habitats at comparable depths. Analysis of the squat lobster fauna of deep-sea habitats in the Southwestern Pacific revealed that the species composition of assemblages on seamounts was not statistically dissimilar from assemblages on slope and plateau habitat at comparable depths. However, compositional differences were observed between seamount and rise and ridge habitat. Differences in assemblage composition between seamount and ridge habitat were statistically significant for two of the four ridge systems examined. Assemblages on seamounts that were distinct from non-seamount ridge habitat were typically dominated by small-bodied species with an abbreviated larval stage. Various environmental variables were correlated with the observed assemblage patterns observed; depth-related variables may account for differences between seamount and rise assemblages, whilst differences in POC flux likely play a role in determining the assemblage compositional patterns between seamount and non-seamount ridge habitat. Extensive pre-analysis data treatment was required to ensure that multivariate analyses of assemblage data from seamount and non-seamount habitats were robust. Our results confirm the findings of recent studies that found no compositional differences in assemblages from seamount and slope habitats, and support the idea that dissimilarity between seamount assemblages on different ridge systems increases with geographic distance. Further research will be required before the generality of these findings can be confirmed.

Résumé [+] [-]The family Ammotheidae is the most diversified group of the class Pycnogonida, with 297 species described in 20 genera. Its monophyly and intergeneric relationships have been highly debated in previous studies. Here, we investigated the phylogeny of Ammotheidae using specimens from poorly studied areas. We sequenced the mitochondrial gene encoding the first subunit of cytochrome c oxidase (CO1) from 104 specimens. The complete nuclear 18S rRNA gene was sequenced from a selection of 80 taxa to provide further phylogenetic signal. The base composition in CO1 shows a higher heterogeneity in Ammotheidae than in other families, which may explain their apparent polyphyly in the CO1 tree. Although deeper nodes of the tree receive no statistical support, Ammotheidae was found to be monophyletic and divided into two clades, here defined as distinct subfamilies: Achelinae comprises the genera Achelia Hodge, 1864, Ammothella Verrill, 1900, Nymphopsis Haswell, 1884 and Tanystylum Miers, 1879; and Ammotheinae includes the genera Ammothea Leach, 1814, Acheliana Arnaud, 1971, Cilunculus Loman, 1908, Sericosura Fry & Hedgpeth, 1969 and also Teratonotum gen. nov., including so far only the type species Ammothella stauromata Child, 1982. The species Cilunculus gracilis Nakamura & Child, 1991 is reassigned to Ammothella, forming the binomen Ammothella gracilis (Nakamura & Child, 1991) comb. nov. Additional taxonomic re-arrangements are suggested for the genera Achelia, Acheliana, Ammothella and Cilunculus.

Résumé [+] [-]A review of species of the deep-sea sponge-associated shrimp genera Spongicola de Haan, 1844 and Paraspongicola de Saint Laurent & Cleva, 1981 (Decapoda, Stenopodidea) is presented on the basis of rich collections made by French expeditions in the Indo-West Pacific, supplemented by collections preserved in various institutions in the world. Seven species are recognized in Spongicola, of which three are new to science: S. venustus de Haan, 1844, S. andamanicus Alcock, 1901, S. levigatus Hayashi & Ogawa, 1987, S. parvispinus Zarenkov, 1990, S. depressus n. sp. from Loyalty Islands, S. goyi n. sp. from Japan, Indonesia, New Caledonia and Vanuatu, and S. robustus n. sp. from Mauritius and Mozambique. Subspecific division of S. andamanicus Alcock, 190 1, proposed by de Saint Laurenr & Cleva (198 1), is abandoned, since our morphological analysis strongly suggests that the division does not reflect a population structure of the species; S. holthuisi de Saint Laurent & Cleva, 198 1, is also reduced to a junior synonym of S. andamanicus. Two species are recognized in Paraspongicola, both previously described, viz. P. pusillus de Saint Laurent & Cleva, 1981 and P. inflatus (de saint Laurent & Cleva, 198 1) n. comb., of which the latter is here transferred from Spongicola.

Résumé [+] [-]A new species of stenopodid shrimp of the genus stenopus, S. goyi, is described on the basis of material from Taiwan, Philippines, Sri Lanka ans the Maldive Islands. The new species is very unusual in that the dactyli of the fourth and fifth pereopods bear one to three ungues. The colouration of the new species is also unique in the genus. The uniunguiculate or biunguiculate dactyli of the ambulatory pereopods were generally considered as a constant character in stenopodid shrimps ans are used for generic diagnosis in the family, but variations in the number of ungues are found in S.Goyi, new species, sometimes even among pereopods of the same specimen. The genus Stenopus is rediagnosed to accommodate the new species. Revised keys to the genera of stenopodidae a,s species of stenopus are provided

Résumé [+] [-]Previous studies have suggested that the high diversity associated with the Norfolk seamounts (Southwest Pacific) could reflect endemism resulting from limited dispersal due to hydrological phenomena. Crustaceans of the family Galatheidae are thoroughly studied in the New Caledonia economic zone permitting the analysis of species distribution pattern between the New Caledonia slope and Norfolk ridge seamounts. This analysis has shown that, qualitatively, the same species are sampled on seamounts and on the New Caledonia slope. Local endemism was never detected. However, on each seamount, and therefore on a small surface, a very high number of species are usually sampled, suggesting that seamounts are biodiversity hot spots. Then, to evaluate whether the seamounts constitute patches of isolated habitat, we explore the pattern of genetic diversity within several species of crustaceans and gastropods. Analysis of the intra-specific genetic structure using the mitochondrial marker COI reveals that populations of two Galatheidae species (Munida thoe and Munida zebra), polymorphic for this marker, are genetically not structured, both among seamounts and between the seamounts and the island slope. The genetic structure over a similar sampling scheme of two Eumunida species (Chirostylidae, the sister family of Galatheidae) and a planktotrophic gastropod (Sassia remensa) reveals a similar pattern. Population structure is observed only in Nassaria problematica, a non-planktotrophic gastropod with limited larvae dispersal. Thus, the limitation of gene flow between seamounts appears to be observed only for species with limited dispersal abilities. Our results suggest that the Norfolk seamounts rather than functioning as areas of endemism, instead, may be highly productive zones that can support numerous species in small areas.

A classification of living and fossil genera of decapod crustaceans. Raffles Bulletin of Zoology suppl. 21: 1–109
Résumé [+] [-]We present an updated classification for the entire Crustacea Decapoda, listing all known families and genera organized by higher taxonomic groups and including estimates of the number of species in every genus. All taxonomic names are also linked to the verified literature in which they were described, the first compilation of its kind for the Decapoda. To arrive at this compilation, we began with the classification scheme provided by Martin & Davis (2001) for extant families,, updated the higher classification and included the fossil taxa. The resultant framework was then populated with the currently valid genera and an estimate of species numbers within each genus. Our resulting classification, spanning both extant (living) and fossil taxa, is the first comprehensive estimate of taxonomic diversity within the entire Decapoda. The classification consists of 233 families of decapods containing 2,725 genera and an estimated 17,635 species (including both extant and fossil species). Of the families in our classification, 53 are exclusively fossil, 109 contain both fossil and extant species, and 71 are extant only. The current estimate for extant species is 14,756, whereas 2,979 species are known exclusively as fossils.

Résumé [+] [-]The monophyletic status of the squat lobster superfamily Galatheoidea has come under increasing doubt by studies using evidence as diverse as larval and adult somatic morphology, sperm ultrastructure, and molecular data. Here we synthesize phylogenetic data from these diverse strands, with the addition of new molecular and morphological data to examine the phylogeny of the squat lobsters and assess the status of the Galatheoidea. A total of 64 species from 16 of the 17 currently recognised anomuran families are included. Results support previous work pointing towards polyphyly in the superfamily Galatheoidea and Paguroidea, specifically, suggesting independent origins of the Galatheidae + Porcellanidae and the Chirostylidae + Kiwaidae. Morphological characters are selected that support clades resolved in the combined analysis and the taxonomic status of Galatheoidea sensu lato is revised. Results indicate that Chirostylidae are more closely related to an assemblage including Aegloidea, Lomisoidea and Paguroidea than to the remaining Galatheoidea and are referred to the superfamily Chirostyloidea to include the Chirostylidae and Kiwaidae. A considerable amount of research highlighting morphological differences supporting this split is discussed. The Galatheoidea sensu stricto is restricted to the families Galatheidae and Porcellanidae, and diagnoses for both Chirostyloidea and Galatheoidea are provided. Present results highlight the need for a detailed revision of a number of taxa, challenge some currently used morphological synapomorphies, and emphasise the need for integrated studies with wide taxon sampling and multiple data sources to resolve complex phylogenetic questions.

Résumé [+] [-]The New Zealand fauna of the crustacean infraorder Stenopodidea, the coral and sponge shrimps, is reviewed using both classical taxonomic and molecular tools. In addition to the three species so far recorded in the region, we report Spongicola goyi for the first time, and formally describe three new species of Spongicolidae. Following the morphological review and DNA sequencing of type specimens, we propose the synonymy of Spongiocaris yaldwyni with S. neocaledonensis and review a proposed broad Indo-West Pacific distribution range of Spongicoloides novaezelandiae. New records for the latter at nearly 54◦ South on the Macquarie Ridge provide the southernmost record for stenopodidean shrimp known to date.

Résumé [+] [-]A cladistic analysis of Neoglyphea inopinata Forest & de Saint Laurent, 1975, clearly reveals that it possesses both of the diagnostic apomorphies for the fractosternalian Reptantia, the fractured or articulated sternum between the seventh and eighth thoracic somites, and the tripartite secula. Furthermore, there is a distinctive epistome form that is otherwise seen only in the freshwater Astacida. These features have implications for the eventual modification of the higher taxonomy and our ideas concerning the evolution of Reptantia.

Résumé [+] [-]A new species of fiddler crab, Uca jocelynae sp. nov., belonging to the U. vocans complex, is described from the islands in Western Pacific on the basis of morphological and molecular data. The new species was previously identified with U. neocultrimana (Bott, 1973) (= U. vocans pacificensis Crane, 1975). The two species can be readily distinguished by characters of the male major chelae, carapace features, and the form of the vulvae. The molecular data of parts of the mitochondrial 16S rRNA and cytochrome oxidase I (COI) genes support that both are sister taxa but nevertheless distinct enough to be regarded as separate species. Uca jocelynae is widely distributed from the islands in the Western Pacific, while U. neocultrimana occurs in Fiji and eastwards.

Résumé [+] [-]Fourty-nine species of Pycnogonida (and six unidentifiable forms) are recorded from the continental slope (200-3740 m) in the Western Pacific off New Caledonia, the Loyalty and Chesterfield Islands, and in the Lau Basin ; only six samples originate from the continental shelf (40-73 m). Of these 49 species, not less than 33 (67 %) are new to Science. The new species belong to the genera Ascorhynchus (3 spp.), Ammothella (1 sp.), Heterofragilia (1 sp.), Cilunculus (4 spp.), Proboehmia gen. Nov. (1 sp.), Sericosura (1 sp.), Rhopalorhynchus (1 sp.), Colossendeis (1 sp.), Hedgpelhia (1 sp.), Austrodecus (5 spp., of which 4 attributed to a new subgenus, Tubidecus), Nymphon (4 spp.), Seguapallene (1 sp.), Parapallene (1 sp.), Pallenopsis s. str. (1 sp.), Pallenopsis (Bathypallenopsis) (1 sp.), Phoxichilidium (2 spp.). Anoplodactylus (1 sp.), and Pycnogonum (3 spp.). The richness in new species is explained by the fact that the bathyal zone around New Caledonia was unexplored so far for Pycnogonida.

Résumé [+] [-]A new species of the crab genus Cosmonotus Adams & White in White, 1848, Cosmonotus mclaughlinae n. sp., is described from the Indo-West Pacific Ocean. This new species inhabits coarse sand and shell bottoms between 75 and 369 m and is so far known from La Réunion, Philippines, Indonesia (Kai Islands), Salomon, Futuna, Vanuatu, Loyalty Islands (Lifou), Fiji, Tonga (N Ha’apai Group). This new species is morphologically close to C. genkaiae Takeda & Miyake, 1970, from which it is easily separated by: 1) the carapace covered by squamiform tubercles (instead of long striae); 2) the lack of the median rostral process (instead of being present and short); 3) the dorsal carpal face of chelipeds with rounded tubercles (instead of striae); and 4) the slender, eyestalks (instead of stout).

Résumé [+] [-]This is part of a series of papers (TAVARES, 1991a, 1991b, 1992a, 1992b, 1992c) reviewing the Cyclodorippidae Ortmann, 1892, and Cymonomidae Bouvier, 1897, of the world. It contains a review of all the Cyclodorippidae from the Indo West Pacific as well as one genus of Cymonomidae. This is a systematic approach preceding a more detailed study of the Cyclodorippoidea morphology and of the phylogenetic relationships within the superfamily. The present work was based upon large collections from the Indo-West Pacific (Madagascar, Japan, Vietnam, Philippines, Indonesia, Australia, Chesterfield Islands, New Caledonia, Loyalty Islands, and Wallis and Futuna Islands) carried out by the following French expéditions : MUSORSTOM 1-7, BIOCAL, CHALCAL 2, CORAIL 2, KARUBAR, LAGON, and SMIB 6. Also included is the material collected by the "Siboga" Expédition, 1899, CRUSTACEA DECAPODA : CYCLODORIPPIDAE ET CYMONOMIDAE 255 "Albatross", 1908, the material collected by the Russian océanographie ships "Orlik" in 1960 on the coast of Vietnam and "Vytiatz" on the west coast of Australia, two samples made by Raoul SERÈNE in Indonesia in during the RUMPHIUS I expédition in 1973 and RUMPHIUS IV in 1975, as well as collections made by the Australian ship "Soela" in 1984 on the north coast of Australia, and others made during the expédition CiDARis I under the auspices of the James Cook University on the Great Barrier Reef. Additional material from the collections of The Natural History Muséum (British Muséum), London ; Museum of Comparative Zoology, Massachusetts ; Zoological Museum of Moscow University ; National Science Museum, Tokyo; Northern Territory Muséum of Arts and Science, Darwin ; Queensland Museum, Brisbane ; South African Museum, Cape Town ; National Museum of Natural History, Smithsonian Institution, Washington and Zoologisch Museum, Amsterdam was also examined. Because of insufficient original descriptions, the re-examination of all type specimens [except for Tymolus truncatus (Ihle, 1916) which is apparently lost and Genkaia gordonae Miyaké and Takeda, 1970] and most of the spécimens cited in the literature, was required to properly establish the correspondence between species and the names introduced in the literature.Until now, seven gênera (Tymolus, Corycodus, Xeinostoma, Genkaia, Krangalangia, Ketamia, and Cymonomus) and23 species of Cyclodorippidae and Cymonomidae were known from the Indo-west Pacific. They are as follows : Cyclodorippidae : Tymolus japonicus Stimpson, 1858, T. uncifer (Ortmann, 1892), T. dromioides (Ortmann, 1892), T. similis (Grant, 1905), T. truncatus (Ihle, 1916), T. brucei Tavares, 1991, Corycodus disjunctipes (Stebbing, 1910), Xeinostoma eucheir Stebbing, 1920, Krangalangia rostrata (Ihle, 1916), K. spinosa (Zarenkov, 1970), Ketamia depressa (Ihle, 1916), Genkaia gordonae Miyaké and Takeda, 1970. Cymonomidae : Cymonomus valdiviae Lankaster, 1903, C. andamanicus Alcock, 1905, C. indicus Ihle, 1916, C. trifurcus Stebbing, 1920, C. japonicus Balss, 1922, C. curvirostris Sakai, 1965, C. aequilonius Dell, 1971, C. bathamae Dell, 1971, C. delli Griffin and Brown, 1976, C. umitake Takeda, 1981, C. hakuhoae Takeda and Moosa, 1990. From this study : — Two new genera (Phyllotymolinum and Elassopodus) and 11 new species of Cyclodorippoidea are herein described : Cyclodorippidae : Corycodus merweae, C. decorus, Xeinostoma richeri, X. sakaii, Krangalangia orstom, Ketamia handokoi, K. limatula, K. proxima, Genkaia keijii, Phyllotymolinum crosnieri. Cymonomidae : Elassopodus stellatus. — Two species are resurrected : Corycodus bouvieri Ihle, 1916, from the synonymy of C. disjunctipes (Stebbing, 1910) and Krangalangia spinosa (Zarenkov, 1970) from the synonymy of A", rostrata (Ihle, 1916).— Four lectotypes are designated here for the following species : Corycodus disjunctipes, Xeinostomaeucheir,Krangalangia rostrata, and Ketamia depressa.Presently, a total of 9 genera (7 Cyclodorippidae and 2 Cymonomidae) and 34 species (22 Cyclodorippidae and12 Cymonomidae) are known from the Indo-West Pacific. All these species are studied here except those belonging to the genus Cymonomus which will be treated in a future publication. Keys for families, genera and species are provided as well as illustrations for all species.

Tavares M. 2000. NEW AND ADDITIONALRECORDS OF CYCLODORIPPIDCRABS FROM JAPAN (BRACHYURA, CYCLODORIPPIDAE). Crustaceana 73(3): 377–378
Résumé [+] [-]Two species of Cyclodorippidae are recorded herein from Japan, Ketamia handokoi Tavares, 1993, and Xeinostoma sakaii Tavares, 1993. This is the first time K. handokoi is referred from outside its type-locality, the Kei Islands in Indonesia. K. handokoi was only known from the male holotype. The opportunity is taken to elaborate on its taxonomy. X. sakaii was previously known from three specimens from Japan (Minabe, Kii Peninsula; Osi Saki) and from one specimen from the Philippines (Tavares, 1993: 292). In this report four more specimens are recorded from additional localities in Japan.

Résumé [+] [-]A population of stone crab (Lithodidae) was encountered on the continental slope off Antarctica in the Bellingshausen Sea between 1,123 and 1,304 m water depths using the ROV-Isis during leg 166 of the RV James Clark Ross, in January 2007. Specimens were video recorded and one specimen was retrieved by ROV for morphological and molecular identiWcation. Based on morphology and molecular data from the mitochondrial COI gene, this specimen identiWed as P. birsteini, Macpherson, 1988a. The significance of the molecular data and their implications for biogeography and evolution of lithodids in the Southern Ocean are briefly discussed.

Résumé [+] [-]The giant bathymodioline mussels from vents have been studied as models to understand the adaptation of organisms to deep-sea chemosynthetic environments. These mussels are closely related to minute mussels associated to organic remains decaying on the deep-sea floor. Whereas biological data accumulate for the giant mussels, the small mussels remain poorly studied. Despite this lack of data for species living on organic remains it has been hypothesized that during evolution, contrary to their relatives from vents or seeps, they did not acquire highly specialized biological features. We aim at testing this hypothesis by providing new biological data for species associated with organic falls. Within Bathymodiolinae a close phylogenetic relationship was revealed between the Bathymodiolus sensu stricto lineage (i.e. "thermophilus'' lineage) which includes exclusively vent and seep species, and a diversified lineage of small mussels, attributed to the genus Idas, that includes mostly species from organic falls. We selected Idas iwaotakii (Habe, 1958) from this latter lineage to analyse population structure and to document biological features. Mitochondrial and nuclear markers reveal a north-south genetic structure at an oceanic scale in the Western Pacific but no structure was revealed at a regional scale or as correlated with the kind of substrate or depth. The morphology of larval shells suggests substantial dispersal abilities. Nutritional features were assessed by examining bacterial diversity coupled by a microscopic analysis of the digestive tract. Molecular data demonstrated the presence of sulphur-oxidizing bacteria resembling those identified in other Bathymodiolinae. In contrast with most Bathymodiolus s.s. species the digestive tract of I. iwaotakii is not reduced. Combining data from literature with the present data shows that most of the important biological features are shared between Bathymodiolus s.s. species and its sister-lineage. However Bathymodiolus s.s. species are ecologically more restricted and also display a lower species richness than Idas species.

Larval stages of the deep-sea lobster Polycheles typhlops (Decapoda, Polychelida) identified by DNA analysis: morphology, systematic, distribution and ecology. Helgoland Marine Research 68(3): 379-397. DOI:10.1007/s10152-014-0397-0
Résumé [+] [-]A total of 25 specimens of Eryoneicus larvae were collected near the Balearic Archipelago (Western Mediterranean Sea) in 2009 and 2010. Detailed morphological examination indicated that the smallest individual corresponded with the first zoea (ZI) stage of Polycheles typhlops hatched from a berried female by Guerao and Abello (J Nat Hist 30(8):1179–1184, 1996). Only two species of deep-sea polychelid lobster, namely P. typhlops and Stereomastis sculpta, are known to occur in the Mediterranean. Genetic distance comparisons and phylogenetic analysis of the mitochondrial 16S rDNA and Cox I genes of this early larva together with adults from several Polycheles and Stereomastis species allowed us to assign it to P. typhlops. This is the first wild-caught larval stage of a polychelid lobster being identified using molecular techniques. The remaining specimens were attributed to zoeal stages II–III and decapodid stage based on morphological comparison. The arrangement of spines along the anterior part of the middorsal line (R, 1, 1, 1, 2, C1), characteristic of the former species E. puritanii, discriminates these larvae from other Eryoneicus found in the Mediterranean. The clear presence of epipods on the third maxilliped and pereiopods of the decapodid stage gives further support to the identification of E. puritanii as the larval stages of P. typhlops. Additionally, information on the ecology of these larvae, their abundances during different seasons, as well as their bathymetric distribution is reported.

Résumé [+] [-]Spiny lobsters (family Palinuridae) are economically important marine animals that have been the subject of a considerable amount of research, However, the phylogeny of this group remains disputed, Morphological analyses have not been able to resolve the relationships of the various members of the group, and no agreement has yet been reached on its phylogeny as indicated by the different gene trees reported to date. In the present study, we attempt to reconstruct the phylogeny of Palinuridae and its allies using sequences from three nuclear Protein-coding genes (phosphoenolpyruvate carboxykinase, sodium-potassium ATPase alpha- subunit and histone 3). The inferred topology receives strong nodal support for most of the branches. The family Palinuridae is found to be paraphyletic with the polyphyletic Synaxidae nested within it. Stridentes forms a monophyletic assemblage, indicating that the stridulating sound producing Organ evolved only once in the spiny lobsters. By contrast, Silentes is paraphyletic, as Palinurellus is more closely related to Stridentes than to other Silentes genera. The three genera restricted to the southern high latitudes Jasus, Projasus and Sagmariasus) constitute the basal lineages in the spiny lobsters, suggesting a Southern Hemisphere origin for the group. Subsequent diversification appears to have been driven by the closure of the Tethys Sea and the formation of the Antarctic circumpolar current, which isolated the northern and southern taxa. Contrary to an earlier hypothesis that postulated evolution from a deep-sea ancestral stock, the shallow-water genus Panulirus is the basal taxon in Stridentes, while the deep-sea genera Puerulus and Linuparus are found to be derived. This indicates that the spiny lobsters invaded deep-sea habitats from the shallower water rocky reefs and then radiated. Our results suggest that Synaxidae is not a valid family, and should be considered to be synonymous with Palinuridae. We also found that the previously proposed subgenera Sagmariasus and Nupalirus are genetically highly diverged, and both warrant a generic status.

Résumé [+] [-]Pea crabs of the superfamily Pinnotheroidea De Haan, 1833 are known for their obligate commensal relationships with other marine invertebrates. The concomitant specialisations and adaptations of pinnotheroids have resulted in superficially similar body forms that include a high degree of structural reduction. This has confounded interpretation of their phylogenetic position in the Brachyura and interrelationships within Pinnotheroidea, though all were nevertheless believed to be united by a monophyletic origin of obligate commensalism. The family Aphanodactylidae Ahyong & Ng, 2009 was proposed for a group of genera associated with tube-dwelling polychaetes formerly classified in Pinnotheridae, and provisionally retained in the Pinnotheroidea. We investigated the phylogenetic position of Aphanodactylidae using molecular data from three markers (mitochondrial 12S and 16S rRNAs, and nuclear histone H3) covering five of the 12 described aphanodactylid species and a total of 15 thoracotreme families. We found Aphanodactylidae to be monophyletic, but widely distant from Pinnotheridae and instead most closely related to Macrophthalmidae (Ocypodoidea) and Varunidae (Grapsoidea). Therefore, the family Aphanodactylidae is corroborated, but its placement in Pinnotheroidea is rejected. Instead, the phylogenetic position of Aphanodactylidae, as clearly distant from other pinnotheroids, demonstrates that obligate commensalism has evolved independently multiple times within Thoracotremata.

Résumé [+] [-]We performed the first cladistic analysis of Metanephrops , the most diverse extant genus of clawed lobster, using a morphology-based data matrix of all 20 species of Metanephrops and 35 cladistically informative characters, all external hard parts. Unweighted cladistic analysis corroborates previous studies that indicated that homoplasy is rampant in the evolution of clawed lobsters. Only 5 of the 68 synapomorphies identified by the analysis are unambiguous, unreversed synapomorphies. Recent species of Metanephrops have traditionally been divided (non-cladistically) into four morphology-based groups. Cladistic analyses support the traditional, arafurensis , Atlantic/ binghami , and japonicus groupings; these groups are monophyletic. The thomsoni group is not supported by the cladogram. The (two) oldest known fossil Metanephrops species occur in Late Cretaceous, shallow marine rocks of the eastern/Atlantic side of the Antarctic Peninsula. The stratigraphic and geographic occurrences of these fossil species are the basis for the previously hypothesized, Late Cretaceous, southern high latitude origin of Metanephrops . Cladistic results corroborate that Metanephrops originated in the southern high latitudes. The cladistically most plesiomorphic single species, the recent M. challengeri , and the next most plesiomorphic species, the Late Cretaceous M. rossensis , are both known from the high southern latitudes. Likewise, the most plesiomorphic species group, the binghami group, is best known from the high southern latitudes.

Résumé [+] [-]Linuparus White, 1847 comprises three extant species, Linuparus trigonus (Von Siebold, 1824), L. sordidus Bruce, 1965, and L. somniosus Berry and George, 1972, as well as 32 fossil species. Most fossil records are from North America and Europe, but the extant species are all confined to the Indo-West Pacific. Different colour forms in L. trigonus and L. sordidus have been noted, with Northern Hemisphere specimens generally darker in colour for both species. The phylogenetic relationships of the extant Linuparus species, including the colour forms, were investigated using mitochondrial 12S rRNA and COI gene sequence analysis. We found no genetic evidence to differentiate the colour morphs of L. sordidus, but the two colour forms of L. trigonus were clearly distinct at the species level. This is supported morphologically by a consistent difference in the shape of the thoracic sternum between the two forms. The paler coloured Southern Hemisphere form is described as a new species, L. meridionalis. Phylogenetic analysis shows that L. trigonus and L. meridionalis sp. nov. are derived sister taxa, while L. somniosus is basal within the genus. Thus the present results support the previous hypothesis that Linuparus was originated in shallow water. Crown Copyright (C) 2011 Published by Elsevier GmbH. All rights reserved.

Résumé [+] [-]Pylochelids, or the “symmetrical” hermit crabs are characterized by paired abdominal appendages (pleopods) on somites 2-6 of the calcified abdomen, in contrast to the asymmetrical pleopods, on an uncalcified abdomen, of the majority of hermit crabs in the superfamily Paguroidea. The spermatozoa of Pylocheles (Bathycheles) sp. are large cells (c. 14 μm wide) with a conspicuous depressed acrosome vesicle in the shape of a thick disk. A perforate (ring-like) operculum is positioned apically on the acrosome vesicle, and a wide, but shallow, perforatorial chamber penetrates the posterior end. Up to three short arms emanate from the cytoplasm of the sperm cell, but it is uncertain if these arms are icrotubular in nature. The spermatozoal morphology provides no evidence for close affinities with any extant hermit crab family and indicates an isolated position for the Pylochelidae, though not incompatible with an origin from an ancestor shared with the Anomura.

Résumé [+] [-]The mantis shrimp superfamily Squilloidea, with over 185 described species, is the largest superfamily in the crustacean order Stomatopoda. To date, phylogenetic relationships within this superfamily have been comprehensively analysed using morphological data, with six major generic groupings being recovered. Here, we infer the phylogeny of Squilloidea using a combined dataset comprising 75 somatic morphological characters and four molecular markers. Nodal support is low when the morphological and molecular datasets are analysed separately but improves substantially when combined in a total-evidence phylogenetic analysis. We obtain a well resolved and strongly supported phylogeny that is largely congruent with previous estimates except that the Anchisquilloides-group, rather than the Meiosquillagroup, is the earliest-branching lineage in Squilloidea. The splits among the Anchisquilloides- and Meiosquilla-groups are followed by those of the Clorida-, Harpiosquilla-, Squilla- and Oratosquilla-groups. Most of the generic groups are recovered as monophyletic, with the exception of the Squilla- and Oratosquilla-groups. However, many genera within the Oratosquilla-group are not recovered as monophyletic. Further exploration with more extensive molecular sampling will be needed to resolve relationships within the Oratosquilla-group and to investigate the adaptive radiation of squilloids. Overall, our results demonstrate the merit of combining morphological and molecular datasets for resolving phylogenetic relationships.

Résumé [+] [-]Four new genera, Eoatria, Poratria, Microporatria, and Multatria, are described, joining the previously described genus Bryozobia in the subfamily Bryozobiinae, a subfamily now represented by ten species of which four are new to science. Evidence is presented that Bryozobia is intimately associated with sponges, rather than bryozoans as Ross and Newman (1996) inferred from the intimate proximity of barnacle and bryozoan calcareous remnants. The four new genera are also associated with burrowing or encrusting sponges and generally possess secondary as well as primary radial atria between their basis and the substratum. The primary atria are aligned with portals in the suture between the wall plates and the basis whereas secondary atria can be parietal as well as interparietal. Eoatria has weakly developed, solid atria aligned with portals in the suture between the wall plates and the basis, but the atrial “ceilings” remain solid. The other genera have atria with pores or slits that develop from portals in the suture between the basis and the wall during ontogeny. All species of Bryozobiinae maintain contact with the substratum via calcareous outgrowths of the basis and/or wall, and their sponge symbiont grows from beneath and around them during ontogeny, nearly encasing them in sponge tissue. The basal atria enable the sponge to grow out from beneath the barnacle, and the evidence suggests chemical mediation by the barnacles induces the sponges to grow up around them, as it does in coral-inhabiting barnacles (Ross and Newman, 2000). This symbiosis apparently also provides the barnacles with a habitat relatively free of spatial competitors as well as protection from various predators, and allows the barnacles to thrive where other encrusting organisms cannot. While the porous, atriate bases found in some of the coralinhabiting barnacles (Pyrgomatidae) are likely convergent, monophyly cannot presently be completely ruled out. The diagnosis of the sponge-inhabiting members of the subfamily Acastinae is amended to include only those species lacking atria that are completely embedded in host tissues: that is, having no basal contact with any other substratum.

Résumé [+] [-]The deep sea is the largest biome on Earth and hosts the majority of as yet undescribed species; description of these may trigger a new mindset about evolution and function of characters. We describe and diagnose a new genus and species Sclerodora crosnieri sp. nov. belonging to the superfamily Oplophoroidea. We examined and coded 81 characters for morphological analyses and used four gene markers for molecular analyses involving the new taxon and representatives of all other genera of Oplophoroidea. Retrieved morphological and molecular trees were similar and suggested that the new genus is a sister group to Hymenodora and both form a clade sister to the rest of Acanthephyridae. We provide an amended key to all genera of Oplophoroidea. We found an unusual chelate structure on the dactyl of the fifth pereopod, tested and confirmed a hypothesis that this structure is common for the whole family Acanthephyridae. We suggest that this derived structure is linked to an active cleaning of branchia—a function associated with chelipeds in some other carid shrimps. Convergent chelate structures are likely efficient for cleaning branchia, whichever appendage is adapted for these functions. In Oplophoridae (sister to Acanthephyridae), cleaning function is carried out by well-developed epipods.

Résumé [+] [-]We describe and diagnose a new species of Acanthephyra (Acanthephyridae: Caridea: Decapoda) and provide an amended key to all species of the genus. In order to assess the taxonomic position of the new species, we examined and coded 55 characters in available specimens of Acanthephyra and ran morphological phylogenetic analyses. We also used a COI gene marker for molecular analyses of the new species and other available specimens of Acanthephyra. Both analyses retrieved an unexpected grouping of species that contradicted a recently accepted morphological grouping. We tested a new, quantitative, set of characters and found that three of them may explain the molecular grouping of the genus. These characters are linked to: (1) proportions of the 6th pleonic somite, (2) length of the same against carapace length, and (3) length of the same against length of two preceding somites. We suggest that these characters mirror evolutionary traits in Acanthephyra and discuss their possible adaptive sense.

Résumé [+] [-]Abstract A phylogenetic study of deep-sea dendrobranchiate genera Altelatipes, Benthesicymus and Benthonectes based on four molecular markers and 91 morphological characters is presented. All currently recognized species of these genera, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. The molecular and morphological methods retrieved similar results, the molecular methods provided better resolution of deeper nodes and higher clade support. Both types of analyses showed paraphyly of Benthesicymus, which encompass five robust clades, four of which are diagnosed as new genera (type species in parentheses): Benthesicymus s.s. (B. crenatus), Bathicaris gen. nov. (Benthesicymus brasiliensis), Dalicaris gen. nov. (Benthesicymus altus), Trichocaris gen. nov. (Benthesicymus bartletti) and Maorrancaris gen. nov. (Benthesicymus investigatoris). Altelatipes was found to be monophyletic. The evolution of the major clades of Benthesicymidae is shown to be linked to trophic specialization, while further divergence at the genus level is mainly related to sexual evolution seen in the elaboration of the copulatory structures. We provide amended diagnoses of the previously recognized and new genera, key to species of each of these genera and include an updated key to genera of Benthesicymidae.

Vereshchaka A.L., Kulagin D.N. & Lunina A.A. 2021. Across the benthic and pelagic realms: a species‐level phylogeny of Benthesicymidae (Crustacea:Decapoda). Invertebrate Systematics 35(7): 776. DOI:10.1071/IS21004
Résumé [+] [-]Benthesicymidae is a monophyletic group of Decapoda adapted to a life on the sea-floor, in the near-bottom layer, in the bathy- and in the mesopelagic, within an impressive depth range from a few hundred metres (Gennadas) to several thousand metres (Benthesicymus). Higher taxa are known to conquer all main oceanic biotopes such as the benthic, benthopelagic, and pelagic and a wide depth range but few family-level groups have clades evolved within all these oceanic realms. Therefore, the global fauna of Benthesicymidae provides a rare opportunity for an insight into phylogenetic processes favouring colonisation of all principal oceanic biotopes. The first comprehensive phylogenetic study of Benthesicymidae (all 37 valid species) is based on six molecular markers and 105 morphological characters (including 72 female and male copulatory characters). Analyses resulted in trees with similar topology and the same set of robust clades. Molecular methods based on 167 sequences (84 new) provided better resolution of deeper nodes and generally higher support of the clades, while morphological methods allowed analyses of all valid species of the global fauna. Phylogenetic analyses support the monophyly and robustness of all currently known genera except Gennadas, which was split into Gennadas Bate, 1881, Amalopenaeus Smith, 1882, and Notogennema gen. nov. We also retrieved two major clades for which we erected two new subfamilies: Benthesicyminae subfam. nov. (presumably benthic, genera Altelatipes, Bathicaris, Benthesicymus, and Benthonectes) and Gennadinae subfam. nov. (presumably pelagic, genera Amalopenaeus, Bentheogennema, Benthoecetes, Boreogennema, Gennadas, Maorrancaris, and Notogennema gen. nov.). We revealed two groups of morphological characters, that are interlinked evolutionarily: (1) petasma and thelycum; (2) body, mouthparts, and pereopods. Morphological traits within benthic and pelagic clades are different, a model explaining the differences is proposed. Along with previous studies, our results confirm the idea that the elaboration of the copulatory structures is a key to successful colonisation of the pelagic realm. These results extend our knowledge about evolution in the largest habitual biotope of our planet and phylogenetic processes favouring colonisation of all principal oceanic biotopes.

Résumé [+] [-]Adult female dajid isopods are ectoparasites found on carapaces, within marsupia, or rarely attached to the eyestalks or pereopods of crustacean hosts. We describe two new genera and species whose females exhibit a novel spheroid shape and envelope antennules of hosts: Akrophryxus milvus n. gen., n. sp. parasitizing Ethusa machaera Castro, 2005 (Madagascar, c. 900 m) and Telephryxus clypeus n. gen., n. sp. parasitizing Munidopsis crassa Smith, 1885 (Caribbean, c. 5000 m). Females of both species differ from other dajid species in their spheroid shape and a plate partially surrounding the host antennule; males are distinguished by reduction of pereopods. Females of A. milvus n. gen., n. sp. are distinguished from those of T. clypeus n. gen., n. sp. in possessing antennules and a triangular attachment plate with three holes (T. clypeus n. gen., n. sp. lacks antennules and the broad attachment plate has two medial holes). Males of A. milvus n. gen., n. sp. are distinguished from those of T. clypeus n. gen., n. sp. in having only six pairs of pereopods, rudimentary antennules, single segmented antennae, and pleon fused to pereomere 7 (T. clypeus n. gen., n. sp. with rudimentary seventh pair of pereopods, large single segmented antennules, two segmented antennae, and pleon distinct from pereomere 7). Pre-molt epicaridium larvae and cryptoniscus larvae of T. clypeus n. gen., n. sp. are described. We also describe Aegophila cappa n. sp. found on pereopods of the isopod Aegiochus symmetrica (Richardson, 1905) (Bering Sea, c. 650 m), distinguished from the type species of Aegophila Bresciani, 1966 by oostegite morphology of the female, form of the antennae, and shape of the pleon of males. Tables with comparative characters for genera of Dajidae G. O. Sars, 1883 are provided. Dajid life cycles and development are reviewed.

Résumé [+] [-]A new species of spider crab, Hyastenus baru n. sp., was collected from deep water off the eastern Indonesian island Kei-Besar by the French-Indonesian KARUBAR expedition in 1991. The new species is similar to several other members of the genus, but differs in spination of the carapace and ambulatory pereopods.

Résumé [+] [-]The United States Food and Drug Administration (FDA) has recently adopted DNA barcoding for the purpose of determining the species identity of commercial seafood products. This effort has revealed instances of incongruence between current scientifically accepted taxon names and those utilized by the seafood industry in product labelling. One such case is that of “ Portunushaanii ”, a name utilized by the seafood industry to label commercial products under the market name “red swimming crab.” However, carcinologists currently regard P.haanii as synonym of Portunusgladiator Fabricius, 1798, which itself is the subject of debate over whether it is a secondary homonym of Cancer gladiator Fabricius, 1793. Further complicating matters, DNA barcode sequences from commercial products match GenBank sequences identified as Portunuspseudoargentatus Stephenson, 1961. Here the complicated taxonomic history of the Portunusgladiator complex is reviewed and a resolution proposed based on combined morphological descriptions and molecular phylogenetic analyses. It is demonstrated that, given the provisions of the International Code of Zoological Nomenclature and the current elevation of Monomia Gistel, 1848, to full genus rank, its type species, Portunusgladiator Fabricius, 1798, should be treated as a valid and available taxon name. It is also shown, upon examination and comparison of types and topotypic material that Monomiahaanii (Stimpson, 1858) is a distinct taxon from M.gladiator , and Portunuspseudoargentatus Stephenson, 1961, is a junior subjective synonym of M.haanii (Stimpson, 1858). Furthermore, it is shown that crab meat sold in the US currently labeled as “ Portunushaanii ” and/or “red swimming crab” is in fact M.haanii using comparative analysis of DNA barcode sequences between museum-vouchered reference specimens, whole crabs provided directly by a seafood importer, and processed commercial products purchased at retail.

Résumé [+] [-]A new species of slipper lobster, Petrarctus holthuisi, new species, is found from the recent expeditions to the Philippines and Vanuatu. The new species resembles P. rugosus (H. Milne Edwards, 1837) but has a different colouration and several morphological differences. Comparisons of the partial sequence of cytochrome c oxidase subunit I (COI) show high degree of divergence (12.5-22.3%) among all the species of Petrarctus. The molecular genetic analysis also suggests that the recent separation of Scyllarus sensu Into may need to be revised. A key to all Petrarctus species is provided.

Résumé [+] [-]The widely distributed deep-sea caridean shrimp Heterocarpus gibbosus Bate, 1888 was previously believed to exhibit considerable variations in the development of the basal rostral crest. Based on the comparison of abundant material from the western Pacific, combined with a molecular genetic analysis using partial sequences of the mitochondrial COI and 16S rRNA genes, three distinct species could be recognized. The true H. gibbosus has a moderately high basal rostral crest and appears to have a more eastern distribution from the South China Sea to the Indian Ocean. Both forms with a very low or very high basal rostral crest are currently undescribed and mainly distributed along the western coast of the Pacific from Japan to Fiji. The low basal rostral crest form, H. abulbus sp. nov., is unique in the genus by lacking a distinct abdominal boss and appears to be restricted to Japan, Taiwan and NE Philippines. The very high basal rostral crest form, H. corona sp. nov., occurs in the western Pacific down to NW Australia.

Résumé [+] [-]Material previously identified as Galearctus kitanoviriosus (Harada, 1962) from New Caledonia has been found to consist of two distinct species. These species differ in the shape of the gastric tooth, third pereiopod propodus, antennal segment IV and thoracic sternum. The shallow water form is the true G. kitanoviriosus, while the deep-water form is new to science. Genetic comparison of the sequence of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), also supports the separation.

Résumé [+] [-]The slipper lobster Chelarctus cultrifer (Ortmann, 1897), a putatively wide-spread Indo-West Pacific species, is well-known in Japan. However, recent collections from Taiwan and the Philippines, and comparisons with material from Indonesia and elsewhere revealed that there are actually two species confused under this name. The two species differ markedly in morphology and colour. On the basis of the lectotype designation of C. cultrifer by Holthuis (2002, from Indonesia), the material from Taiwan and Japan is shown to be actually undescribed and is named herein. Chelarctus cultrifer sensu stricto is restricted to the material from the more southern localities in the Philippines westwards to Iles Glorieuses. Genetic comparison of sequences of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), supported the species separation. The molecular data further suggested that two genetic forms are present within C. cultrifer sensu stricto, and therefore, the subspecific name C. cultrifer meridionalis (Holthuis, 1960) is resurrected.

Résumé [+] [-]The slipper lobsters belong to the family Scyllaridae which contains a total of 20 genera and 89 species distributed across four subfamilies (Arctidinae, Ibacinae, Scyllarinae, and Theninae). We have collected nucleotide sequence data from regions of five different genes (16S, 18S, COI, 28S, H3) to estimate phylogenetic relationships among 54 species from the Scyllaridae with a focus on the species rich subfamily Scyllarinae. We have included in our analyses at least one representative from all 20 genera in the Scyllaridae and 35 of the 52 species within the Scyllarinae. Our resulting phylogenetic estimate shows the subfamilies are monophyletic, except for Ibacinae, which has paraphyletic relationships among genera. Many of the genera within the Scyllarinae form non-monophyletic groups, while the genera from all other subfamilies form well supported clades. We discuss the implications of this history on the evolution of morphological characters and ecological transitions (nearshore vs. offshore) within the slipper lobsters. Finally, we identify, through ancestral state character reconstructions, key morphological features diagnostic of the major clades of diversity within the Scyllaridae and relate this character evolution to current taxonomy and classification.

Résumé [+] [-]The commercial deep-sea penaeid shrimp genus Parapenaeus contains 15 species, three subspecies and two forms in the Indo-West Pacific and the Atlantic. Novel nucleotide sequence data from five different genes (COI, 16S, 12S, NaK and PEPCK) were collected to estimate phylogenetic relationships and taxonomic status amongst all but one subspecies in this genus. The phylogenetic results only support two of the four species groups previously proposed for this genus and indicate an evolution direction of the genital organs from simple to complex. The present results suggest that Parapenaeus originated in the shallow waters of the West Pacific with subsequent migration to the deep sea and the Atlantic. The molecular data reveal that there was probably misidentification of females between Parapenaeus australiensis and Parapenaeus ruberoculatus, with females previously assigned as P. australiensis likely being the females of P. ruberoculatus, while material identified as P. australiensis forma nodosa being the true P. australiensis females. On the other hand, Parapenaeus longipes forma denticulata truly represents a variation of the same species, while the subspecies Parapenaeus fissuroides indicus warrants a specific rank.

Résumé [+] [-]The availability of fresh specimens of the commercial, deep-sea pandalid shrimp, Heterocarpus woodmasoni Alcock, 1901, from India revealed that material referred to this species from India and the western Pacific Ocean have distinct differences in coloration, morphology, and genetic divergence. Although the syntypes of H. woodmasoni cannot be located now, a color photograph of a typotypic specimen from the Andaman Sea allowed the determination of the Indian form as the true H. woodmasoni. To stabilize the taxonomy in the “H. woodmasoni” species group, a neotype is selected for H. woodmasoni from an Indian specimen with both coloration and molecular barcoding information. The western Pacific form is described as a new species, Heterocarpus fascirostratus sp. nov., which differs from H. woodmasoni in having a banded rostrum, eggs reddish brown instead of greenish brown, lacking rostral crest, armed usually with fewer dorsolateral spines on the telson, the overhanging spine on the abdominal somite III not markedly recurved downwards, and a rather straight postantennal carina.

Résumé [+] [-]A large, geographically diverse selection of scleractinian corals, mostly ahermatypes, has been surveyed for galls caused by endoparasites of the ascothoracid family Petrarcidae, which till now have only been known from very few examples. Approximately 30 species of coral in 3 suborders, comprising about 70 distinct populations worldwide (concentrated in the Indo-West Pacific) , from the surface to 5 870 m, bear such galls. Most galls occur within calices (internal galls), but some colonial corals bear galls on their surface independent of calices (external galls); both kinds have a spongy texture that often involves substantial alterations of the host skeleton. Photographs of many infested corals are included. The apparent process of development of both types of gall is described. Parasites themselves were found in about one third of the infested populations and were referable to at least 8 species in 3 genera of Petrarcidae; most of these have been described elsewhere, but a few new records are given here. Preliminary remarks on host-parasite specificity are given.

Mémoires du Muséum national d'histoire naturelle Tome 213. Publications scientifiques du Muséum national d'histoire naturelle, Paris:369-402, ISBN:978-2-85653-913-2
Résumé [+] [-]Material collected during the expeditions BIOPAPUA 2010, PAPUA NIUGINI 2012, MADEEP 2014, and KAVIENG 2014, in the waters of the Bismarck and Solomon Seas of Papua New Guinea (PNG) yielded 12 species of deep-sea shrimps of the family Palaemonidae. Besides one new species of the genus Amphipontonia described in this paper, seven others, namely Bathymenes aleator, Echinopericlimenes calcaratus, Palaemonella dolichodactylus, P. komaii, P. spinulata, Periclimenes laccadivensis, and P. uniunguiculatus, are new records for Papua New Guinea. An extension to the known bathymetric range is reported here for the deep-water species Palaemonella dolichodactylus, P. komaii, P. spinulata, and Periclimenes uniunguiculatus, and also for two species previously considered as restricted to shallow water, i.e., Laomenes amboinensis and Ancylomenes sp., collected from depths over 90 and 180 m, respectively. Based on the present molecular analysis and additional GenBank sequences, three deep-water Periclimenes species, i.e., P. boucheti, P. leptunguis, and P. sandybrucei, are formally transferred here to the genus Bathymenes, and B. brevirostris is synonymized with B. aleator.

Résumé [+] [-]Multigene molecular revision of a series of specimens of the rare spongobiotic palaemonid shrimp genus, Onycocaridella Bruce, 1981, collected predominantly from Papua New Guinea, has doubled the known species diversity to six. Of the previously known species, O. monodoa (Fujino & Miyake, 1969) and O. stenolepis (Holthuis, 1952) were analysed in the present study, whereas sequenceable specimens of the type species, O. prima Bruce, 1981, were not available. The present molecular analysis (combined COI, 16S, H3 markers) recovered six separate genetic lineages, indicating the presence of four undescribed species. Three of the latter are described in the present study. Remarkably higher known species diversity of Onycocaridella is thus recorded from a single geographic region – Papua New Guinea. The increased diversity reported here was discovered by application of complementary collecting techniques (hand picking, stone brushing, dead-coral sorting, suction sampling). One of the present new species is also reported from Australia, and O. monodoa is newly recorded from New Caledonia. A revised diagnosis of the genus and a key to identification of all known species of Onycocaridella are provided.

Résumé [+] [-]A very small adult specimen of symbiotic palaemonid shrimp collected from Kavieng Lagoon, N.W. New Ireland Island, Papua New Guinea, is described as a new genus and species. Due to the slender subcylindrical body, reduced rostrum, elongated eyes and distolaterally produced uropodal exopods, the new species is somewhat similar to shrimps of the endosymbiotic sponge genus Nippontonia. Both second pereiopods are lost, but the specimen is unique by its bidentate scaphocerites, an apical corona of spiniform teeth on the mandibular molar process, five posterior telson cuspidate setae from which the median and intermediate ones are long, hooked, and the broadly spoon-like dactyli of the first pereiopods chelae with marginal pectination. Based on those characters, the new genus is without parallel among all symbiotic palaemonid shrimps. Its close phylogenetic relationship to the spongobiotic genera Nippontonia, Onycocaridella, and Thaumastocaris, is also confirmed by molecular comparison.

Phylogenetic relationships of Gelidiella (Gelidiales, Rhodophyta) from Madagascar with a Description of Gelidiella incrassata sp. nov. Cryptogamie, Algologie 36(2): 219-237. DOI:10.7872/crya.v36.iss2.2015.219
Résumé [+] [-]We evaluated the relationships among species in the genus Gelidiella using 47 rbcL and 29 COI sequences, including those from 18 specimens collected in Madagascar. Molecular analyisis revealed the presence of three major lineages among Magalasy Gelidiella which were assigned, based on morpho-anatomical observation, to Gelidiella acerosa, G. ligulata and a so far not described species for which we here proposed the name G. incrassata. Both molecular and morphological data demonstrated the presence of three species in Madagascar: the G. acerosa complex, G. ligulata, and G. incrassata sp. nov., described here. Gelidiella incrassata was collected on small gravel from the intertidal down to a depth of 14 m on the southeast coast of Madagascar. It is distinguished by its large size (up to 7 cm), opposite to alternate ramuli, thick-walled cortical and medullary cells, and stalked tetrasporangial stichidia with irregular arrangement of tetrasporangia. Phylogenetic analyses of rbcL and COI sequences revealed the sister relationship between G. incrassata and G. fanii from southeast Asia and Hawaii. Gelidiella acerosa comprised three genetic groups in Madagascar, each being genetically distinct (pairwise distances, 4.9–8.3% for COI and 1.2–2.3% for rbcL). Further sampling of G. acerosa is needed before taxonomic revisions can be proposed. The distribution of G. ligulata is expanded to include the southwest Indian Ocean.

Résumé [+] [-]We analyzed both mitochondrial cox1 and plastid rbcL sequences from specimens of Pterocladiella from Madagascar and compared their morphologies with previously described species in the genus. Both molecular and morphological datasets demonstrated the presence of five species in Madagascar: P. australafricanensis, P. bartlettii, P. caerulescens, and two new species, P. feldmannii and P. hamelii, described here. Pterocladiella feldmannii is distinguished by plants with a size of about 6 cm with narrow axes and opposite to irregular branches, rhizines congested in medulla, tetrasporangial branchlets constricted at base of branches, tetrasporangial sori without sterile margins, and irregular arrangement of tetrasporangia. Pterocladiella hamelii is characterized by plants with a size of about 3 cm with flattened and thin erect axes and irregular branches, radial arrangement of subapical cells at tips of main axes, tetrasporangial sori with sterile margins and horizontal to irregular arrangement of tetrasporangia. Phylogenetic analyses based on cox1 and rbcL sequences revealed the sister relationship between P. feldmannii and P. hamelii, and their distant relationships to P. australafricanensis, P. bartlettii, and P. caerulescens. The Madagascan Pterocladiella is composed of two geographical elements: Madagascan endemic (P. feldmannii and P. hamelii) and species with wide distributions (P. australafricanensis, P. bartlettii and P. caerulescens).

DOI:10.3389/fpls.2022.849476
Résumé [+] [-]We investigated the globally distributed red algal genus Pterocladiella , comprising 24 described species, many of which are economically important sources of agar and agarose. We used DNA-based species delimitation approaches, phylogenetic, and historical biogeographical analyses to uncover cryptic diversity and infer the drivers of biogeographic patterns. We delimited 43 species in Pterocladiella , of which 19 are undescribed. Our multigene time-calibrated phylogeny and ancestral area reconstruction indicated that Pterocladiella most likely originated during the Early Cretaceous in the Tethys Sea. Ancient Tethyan vicariance and long-distance dispersal have shaped current distribution patterns. The ancestor of Eastern Pacific species likely arose before the formation of the formidable Eastern Pacific Barrier—a first confirmation using molecular data in red algae. Divergences of Northeast and Southeast Pacific species have been driven by the Central American Seaway barrier, which, paradoxically, served as a dispersal pathway for Atlantic species. Both long- and short-distance dispersal scenarios are supported by genetic relationships within cosmopolitan species based on haplotype analysis. Asymmetrical distributions and the predominance of peripatry and sympatry between sister species suggest the importance of budding speciation in Pterocladiella . Our study highlights the underestimation of global diversity in these crucial components of coastal ecosystems and provides evidence for the complex evolution of current species distributions.

Résumé [+] [-]The diversity of red algae is significantly increasing; in the recent interest of climate changes, taxonomic and biogeographic studies are needed in untouched regions such as ecological important islands. We examined a collection of Gelidium specimens gathered during the 2010 Atimo Vatae expedition based on the morphology and DNA sequencing of mitochondrial cox1 and plastid rbcL. Both morphological and molecular datasets demonstrated the presence of three species in Madagascar; G. leptum G.H.Boo, L.Le Gall and H.S.Yoon, sp. nov., described here, and G. sclerophyllum W.R.Taylor and G. usmanghanii Afaq-Husain and Shameel. Gelidium leptum is distinguished by thin, slender, flattened thalli with irregular branches, compactly arranged thickwalled cells in medulla, sparse rhizoidal filaments at both sides of branches, and elongate sori of tetrasporangia. Gelidium sclerophyllum, previously considered as endemic to the Tropical Eastern Pacific, is first reported in the Indian Ocean and Hawai’i; G. usmanghanii, previously reported to occur in Pakistan and Oman, also presents a first record in the Southern Hemisphere. Phylogenies inferred from cox1 and rbcL sequences suggests that each of the three species likely diverged from different ancestors. The Madagascan Gelidium comprises two geographical elements; Madagascan endemic (G. leptum) and widespread species (G. sclerophyllum and G. usmanghanii).

Molecular and ultrastructural characterization of two ascomycetes found on sunken wood off Vanuatu Islands in the deep Pacific Ocean. Mycological Research 113(12): 1351-1364. DOI:10.1016/j.mycres.2009.08.015
Résumé [+] [-]A new genus of a deep-sea ascomycete with one new species, Alisea longicolla, is described based on analyses of 18S and 28S rDNA sequences and morphological characters. A. longicolla was found together with oceanitis scuticella, on small twigs and sugar cane debris trawled from the bottom of the Pacific Ocean off Vanuatu Islands. Molecular and morphological characters indicate that both fungi are members of Holosphaeriaceae. Within this family, O. scuticella is phylogenetically related to Ascosalsum and shares similar ascospore morphology and appendage ontogeny. The genus Ascosalsum is considered congeneric with Oceanitis and Ascosalsum cincinnatulum, Ascosalsum unicaudatum and Ascosalsum viscidulum are transferred to Oceanitis, an earlier generic name.

Deep Sea Research Part I: Oceanographic Research Papers 55(8): 1035-1047. DOI:10.1016/j.dsr.2008.04.004
Résumé [+] [-]Seamounts are habitats of considerable interest in terms of conservation and biodiversity, and in terms of fisheries for bentho-pelagic and pelagic species. Twenty previously compiled datasets including seamount/underwater feature lists, bathymetric maps and emerged feature maps from different sources (ship-derived and satellite altimetryderived) at different spatial scales (from individual cruise to worldwide satellite data) were gathered in order to compile an enhanced list of underwater features for parts of the western and central Pacific Ocean (WCPO). The KL04 dataset [Kitchingman, A., and Lai, S., 2004. Inferences on potential seamount locations from mid-resolution bathymetric data. Fisheries Centre Research Reports 12 (5), 7–12], listing seamount positions and depths as calculated from satellite altimetry-derived bathymetry, provided the baseline data for this study as it covered the entire region of interest and included summit depth information. All KL04 potential seamounts were cross-checked with other datasets to remove any atolls and islands that had been incorrectly classified as seamounts, to add seamounts undetected by KL04, to update the overall database (geolocation, depth, elevation, and name) and to compile a 12-class typology of the different types of underwater features. Of the 4626 potential seamounts identified in KL04, 719 were multiple identifications of the same large underwater features and 373 (10%) were actually emerged banks, atolls and islands, leaving 3534 actual underwater features. Conversely, 487 underwater features were documented in other datasets but not registered by KL04. The screening of all the potential WCPO seamounts produced a final list of 4021 underwater features with agreed upon position and information. This enhanced list should have many applications in oceanography, biodiversity conservation and studies of the influence of seamounts on pelagic ecosystems and fisheries.

Résumé [+] [-]The exploratory fishing survey ZoNéCo 6 was canied out on board the R.Y. Alis of the IRD (Institut de Recherche pour le Développement) from 1-14 Décember 1998. lts main objective was to show whether commercial fish resources are present at depths between 300 and 800 m on the outer reef slopes of the Fairway-Lansdowne Bank and the Chesterfield Atoll. Two fishing techniques were used, bottom trawling and bottom longlining. The choice of fishing spots was based on both acoustic surveys using a 28 kHz FURUNO FCY 292 and the bathymetric charts produced during the seabed mapping survey ZoNéCo 4 canied out by the R.Y. L'Atalante. The duration of the trip was splitted into 41, l % devoted to transit, 27 % to bathymetry, 22.3 % to fishing and 9,6 % to waste of time due to bad weather conditions. 17 fishing stations were completed of which 9 were trawl hauls and 8 bottom longline sets amounting to a fishing effort close to 5000 hooks. Three trawl stations and 3 longline sets were made on the slopes of the Chesterfield Atoll whilst 6 trawl stations and 5 longline sets were completed on the slopes of the Fairway-Lansdowne Bank. The total catch was 822 kg of which 243 kg were caught with the trawl and 579 kg with the longline. The trawl did not catch any commercial species, shark amounting to 42 % of the catch, bone fishes 40 %, Crustaceans 9 % and Cephalopods 9 %. The average trawl catch rate was 0,6 tonne/km2 (6,06 kg/ha). The only commercial species caught with the longline were « red snappers» Etelis . carbunculus and E coruscans amounting to 211 kg (36,4 % of the total weight) with a catch rate of 4,3 kg/100 hooks. Sharks dominated the catch both in terms of number and weight (320 kg amounting to 55,3 % of the catch). Gnly one Beryx splendens was caught. With the exception of « red snappers », the survey did not show the presence of commercial target resources within the 300-800 m depth range of the prospected area.

Résumé [+] [-]The following results are deduced from radiocarbon and oxygen 18 curve datings obtained in Quaternary hemipelagic deposits cored off SW and SE slopes surrounding New-Caledonia: _ the radiometric age of total sediment (periplatform ooze + calcareous planctonic remains) exceeds that derived from the 8(18)0 curve yielded by Orbulina universa; _the rate of sedimentation strongly decreases, principally off southwestern coasts, during the last 16,000 years. This is a probable consequence of the screen-effect of the reefal Quaternary belt, enhanced by the Flandrian transgression.

Résumé [+] [-]Submarine slopes and basins off New-Caledonia (South-Western Pacifie); morphology, biosedimentary environments, sedimentation During the Biocal deep-sea cruise off New-Caledonia, fauna and sediments were sampled and Seabeam maps were drawn. The first geological results are as follows: - block-faulting determines the morphology of the slopes, their erosion and the transport of sediments along them towards the Loyalty basin plain; - erosion is predominant in the studied areas of the western Caledonian slopes and along the slopes off Lifou island where the canyons are broad and scattered, whereas in front of the "passe de Thio", through the reefal barrier, a relatively high detritic influx transits through several narrow canyons; - the Loyalty basin has been explored along the Thio-Lifou transect; it exhibits a flat bottom and is fed mainly from the eastern Caledonian slopes by calcareous and argilaceous turbidites, which spread eastward over nearly 50 km and interfinger with hemipelagites; - the sediments are constituted by 5 distinct components: 15 to 50% of detritics from New-Caledonia (mainly clay minerais, iron oxydes and silicate minerais); 15 to 25% bioclastic silts and sands derived from the reefal ring and from the lagoon; mixed bioclasts ( 1 to 20%) furnished by benthonic communities living on the slopes and in the basin; planktonic debris (30 to 75%) with a dominant fraction composed of foraminifers and pteropods; and volcanic debris (0,5 to 10%). A sedimentation rate of about 6cm/1000 years (between 16000 and 5000 years B.P.)has been estimated from the explored sector of the Loyalty basin.

Résumé [+] [-]Basins and their edges were surveyed during crui ses of ENVIMARGES program in the vicinity of New Caledonia. Quaternary deposits include a major carbonate fraction mainly issued from plankton and reef systems surrounding the lands (New Caledonia and Loyalty islands) and a rather argillaceous terrigenous fraction derived from New-Caledonia. SW of New-Caledonia and on both sides of Lifou islands, the submarine slopes are concave and intensely eroded. At the foot of them and beyond, the sedimentation is weak and carbonate-rich. NE of New-Caledonia, the slope is straight and also actively eroded; carbonate and terrigenous material by-pass along it ; slumps and debris-flows accumulate down the slope and turbidites spread over the Loyalty basin. The major features of sedimentation are then splitted between two poles defined by platform and hinterland characteristics: a carbonate pole, comparable with that of the Bahamas, and a mixed carbonate and siliciclastic pole from what the originality of this depositional area is derived and which is determining the fastest sedimentation. The whole system is also dependent on climatic and eustatic Quaternary fluctuations. Interglacial periods are marked by reef growth and carbonate enriched deposits, particularly with aragonite. Reversely, carbonate impoverishments and biological silica enrichments are observed in sediments during glacial periods. The system is also controlled by tectonics but through still undetermined degree and process . The most recent described "Carbonate platform-slope-basin" systems depend on an exclusive carbonate pole. However slope erosions so clear and important as off New-Caledonia are not quoted.To some extent, the behaviour of Loyalty basin during the Quaternary can help in the comprehension of ancient basins. However, a comparison with the Loyalty basin shows the difficulty for restituting palaeomorphologies. In addition , it may be hazardous to use directly observations on a present basin for a better knowledge of ancient sedimentary systems because of scale changes concerning time and the network of observations.

Debenay J.P. 2012. A guide to 1,000 foraminifera from Southwestern Pacific: New Caledonia. IRD Editions
Résumé [+] [-]The first part of this guide is designed to introduce the reader to New Caledonia, a French archipelago in the tropical-subtropical southwestern Pacific (latitude 15°-26° S and longitude 156°- 174°E), with the main island (400 km long and 50 km wide) being the third largest island in the southwestern Pacific after New Guinea and New Zealand. It presents an overview of the geologic, geomorphic, oceanographic and climatic setting of New Caledonia at general, regional, and local scales. Then, the current knowledge of foraminifera, including biology and the main test components used for identification is summarized and illustrated. It is mostly destined for non-specialists and people new to foraminifera. In the following chapters, foraminiferal studies of New Caledonia are synthesized, with emphasis on studies carried out in lagoonal, reefal and paralic environments during the past 35 years, including distribution maps of the main species, distribution models related to depth and mud content of the sediment, and examples of foraminifera as environmental indicators at various space and time scales. The main part of this work is a guide to the taxonomy and identification of benthic foraminifera that are very diversified and abundant around New Caledonia. It aims to assist micropaleontologists and students of foraminifera, but also to provide a resource for environmental managers and scientists who may use foraminifera as a tool for environmental monitoring and assessment, without being specialists of this group. For achieving this goal, species are classified by the nature of the wall and the dominant morphological feature. First, a photographical summary presents full-page plates showing small images of all species divided into agglutinated, porcelaneous and hyaline, with the hyaline species further classified by the coiling mode. It will allow an easy comparison between related species and a quick pre-identification of specimens before advancing to the next chapter for confirmation on the basis of descriptions and larger photographs of the species. At the end of the book, and mostly for specialists, a systematics list of foraminiferal species identified from New Caledonia is provided, with a brief synonymy list including the original type reference, and a few references that illustrate the species clearly. Systematics is organized following LOEBLICH & TAPPAN (1992, 1994) and KAMINSKI (2004). A total of 1,043 species are described and illustrated by scanning electron and light microscope photographs. They were collected from over 800 samples that span 0-700 m water depths in a high diversity of habitats including mangrove, estuaries, lagoons, coral reef and shelf. Among them, 665 had not been reported around New Caledonia before the compilation published in 2007. Two new species are described: Triloculina elongotricarinata and Hoeglundina neocarinata, a new species name is proposed for Calcarina exuberans, instead of Calcarina hispida var. pulchella, and a new genus name is proposed for Quirimbatina rimosa instead of Mimosina rimosa. One hundred and forty-two species could not be determined at a specific level and are recorded under open nomenclature. A high proportion of them are presumably new species, but more specimens are needed before proposing new species names. Including the 158 species reported in the literature, and not found for being illustrated in this book, the number of benthic foraminifera species identified hitherto around New Caledonia reaches 1,201. Most of them had been reported from the central and western Pacific, and/or the Indo-Pacific area, but some species had been found from remote areas, such as the spectacular Quinqueloculina erinacea Mikhalevich, reported fromthe tropical Atlantic, or Rotaliammina siphonata (Seiglie), reported from Venezuela, showing the high dispersal potential of some species.

Résumé [+] [-]A new species of pterobranch has been found that has features that could resolve the longstanding arguments by palaeontologists about how the fossil graptolites produced their elaborate extra-corporeal homes. Many complex and biologically highly unlikely solutions previously proposed can be simplified. This animal is probably classifiable as a graptolite and thus a living fossil, representing a group thought to be extinct for 300 million years.

Later collection in Western Pacific by author and colleagues have provided three new species, thus raising to 33 species the total number of known species in that genus. Plectranthias maculatus, from the Philippines, caught bettween 129 and 177 m depths by trawl-nets, is distinguished from the other Plectranthias species through its high gillrakers count - 30 to 31, it deep body , steep snout profile, and a large dark brown spot on its back, just below three dorsal fins. Plectranthias barroi, from the Chesterfield Islands (Coral sea) in 300 depths, is very distinctive among the other known species of Plectranthias with a peculiar filamentous ventral rays, and elongated rays in anal and caudal fins. Chelidoperca lecromi, also from the Chesterfield Islands, same depths as P. barroi, differs from other Chelidoperca by its yellow colour and belly striped. The interorbital space of that new species is covered with a scaled band, as C. hirundinacea from which it seprates by lower gill rakers counts (14 vs 18), lower number of pectoral rays (15 vs 16) and of scale rows above lateral line (3 vs 4). Its dorsal spines display a slight curvature close ti their tip, while they are all straight in C. hirundinacea

Gaillard C. 1988. Bioturbation récente au large de la Nouvelle-Calédonie. Premier résultats de la campagne Biocal. Oceanologica Acta 11(4): 389-399
Résumé [+] [-]This preliminary study deals with deep-sea biogenic traces and bioturbation off New Caledonia. All the data were obtained during the Biocal multidisciplinary (biology/geology) cruise aboard the oceanographie vessel Jean-Charcot (summer 1985). The studied area was chiefly along a transect extending from Thio to Lifou across the Loyalty basin. An initial inventory of superficial biogenic traces and sorne reflections concerning their distribution are given. Certain traces correspond to ichnogenera rarely or not found on modern oceanic floors but weil known in deep-sea fossil deposits (Paleodictyon, Urohelminthoida). In contrast with plain pelagie environments, the bioturbation is very variable. Indeed, the benthic life is frequently disturbed by turbidites and mud flows. Bioturbation is closely dependent on these sedimentary perturbations, and seems to be conditioned by the thickness and frequency of turbiditic deposits, size and shape of particles, and occurrence of a predepositional erosive phase. The effects of bioturbation have been analysed in connection with the obliteration of contacts between hemipelagites and turbidites and with the progressive disappearance of sorne thin turbiditic deposits. These observations and corresponding conclusions underline the interest of studying bioturbation for the analysis of fossil deposits containing hemipelagites and turbidites.

Résumé [+] [-]L'intérêt paléoenvironnemental des traces fossiles est bien connu des géologues. De même, l'importance de la bioturbation ou de la biocorrosion, dont elles sont l'expression, est considérable dans la dynamique sédimentaire. Or l'interprétation correcte de ces objets et de ces phénomènes ne peut progresser sans une meilleure connaissance de leurs équivalents actuels ou récents. Bien connus en milieu littoral, ils le sont beaucoup moins en milieu marin profond. D'où l'intérêt du programme ENVIMARGES qui a permis de multiples observations sur les pentes et dans les bassins au large de la Nouvelle Calédonie, dans un intervalle bathymétrique de moins de 100 m à plus de 3000 m. Les moyens d'investigation utilisés ont été nombreux et complémentaires. Les traces biologiques de surface ont ainsi été étudiées par observation directe depuis la soucoupe Cyana (CALSUB), par photographie automatique avec une caméra ponctuelle (BIOGEOCAL) ou commandée depuis la soucoupe (CALSUB), par film vidéo (CALSUB) et même par carottage grande surface Usnel (BIOCAL, BIOGEOCAL). Certaines traces profondes et les sédiments bioturbés ou biocorrodés ont été prélevés par carottage Usnel ou Kullenberg, dragage et chalutage (BIOCAL, BIOGEOCAL) ou directement par le bras préhensile de la soucoupe (CALSUB). Le but de ce travail est de rassembler les principales observations réalisées au cours des différentes campagnes et de présenter d'une manière synthétique et très simplifiée quelques résultats d'intérêt général.

Gaillard C. 1991. Recent Organism Traces and Ichnofacies on the Deep-Sea Floor off New Caledonia, Southwestern Pacific. PALAIOS 6(3): 302. DOI:10.2307/3514910
Résumé [+] [-]The deep-sea floor off New Caledonia was investigated during three successive multidisciplinary (biology/geology) cruises from 1985 to 1989: BIOCAL, BIOGEOCAL, and CALSUB. The main study area is the Loyalty Basin, which comprises a deep (2300 m) trough with a flat bottom and steep slopes topped by coral reefs. This basin is filled by a thick sequence of Recent hemipelagic muds and turbiditic sands, silts and muds. The slopes, which are strongly eroded, are locally covered by a thin layer of recent hemipelagic muds. Many biogenic traces occur in all muddy deposits. The trace assemblages of the basin bottom characterizes typical deep-sea ichnofacies with burrows, mounds, tracks, trails, and fecal castings. Two main ichnofacies are evidenced: a deep slope ichnofacies and a deep plain ichnofacies. The distribution of biogenic traces is probably controlled by the greater food supply on the slopes. The main trace makers that could be identified are holothurians and enteropneusts. Some traces, sampled by boxcoring, correspond to ichnogenera that are well known in fossil deposits (e.g., Paleodictyon and Urohelminthoida. One novel trace occurs on bathyal slopes, at depths exceeding 1300 m. It is made up of one mound and several holes forming a horseshoe ("Fer d Cheval") = the FC trace. It is strictly restricted to the slope, oriented according to the declivity, and very common between 1600 and 2000 m. So, this trace provides a very good environmental index. Bioturbation and erosion strongly hinder the preservation of these biogenic traces. Rapid burial by slightly or non destructive distal turbidites seems to be the only possible fossilization process.

Résumé [+] [-]Dans le cadre de l'initiative pour les récifs coralliens du Pacifique sud (CRISP), lancée en janvier par l‘AFD, le WWF-France a souhaité développer un projet pour la protection des récifs et des lagons néo-calédoniens. Ce projet s’inscrit dans la composante 1 du CRISP, pilotée par Conservation International. Le projet développé par le WWF-France a 3 objectifs : - Réaliser l’analyse écorégionale marine (AER) de la Nouvelle-Calédonie. L’AER est destinée à identifier, à une échelle géographique cohérente, un réseau d’aires prioritaires, d’intérêt majeur pour la conservation de la biodiversité et des ressources marines, et à rassembler les acteurs (scientifiques, politiques, communautés locales) autour d’une vision et d’une stratégie communes pour leur protection. Ce travail d'analyse écorégionale est conduit en étroite coordination avec le processus d'inscription du lagon de Nouvelle-Calédonie au Patrimoine mondial. Il a notamment pour objectif de participer à l'identification et à la description des sites à inscrire au Patrimoine mondial, et à fournir des éléments sur leur valeur universelle. - Accompagner les Provinces dans la création et la gestion d’aires marines protégées. La zone du Mont Panié pour la Province nord et la réserve Yves Merlet, pour la Province sud, ont à ce jour été identifiées. - Renforcer les capacités des gestionnaires et capitaliser les expériences en matière de création et de gestion d’aires marines protégées (AMP). L’atelier, qui s’est déroulé les 10 et 11 août à Nouméa, s’inscrit dans le cadre de l’AER. Il avait pour objectif de rassembler les scientifiques et les experts du lagon néo-calédonien pour identifier, sur la base de leur connaissance experte, les zones les plus remarquables du lagon, sur lesquelles doivent porter en priorité les efforts de conservation.

Résumé [+] [-]The exploratory bottorn trawling survey HALIPRO 2 was carried out from 4 to 28 November 1996 on board the New Zealand research vessel Tangaroa of NIWA (National Institut ofWater and Atrnospheric Research Ltd). It was aimed at identification of deep fishery resources over the Norfolk Ridge and the southern part of the Loyalty Ridge. This zone, the area of which is 73000 square km, was previously rnapped during the seabed rnapping survey ZoNéCo 1. A trawl similar to the one used by the New Zealand commercial deep bottom fishing boats was used. Amongst 35 persons on board, 17 were scientists from different countries with different fields of research. A total of 3755 nautical miles were covered and 106 hauls were made. The environment was studied through temperature and salinity profils down to 1500 m and CUITent records down to 300 ffi. The presence of alfonsino (Beryx splerulens) was confirmed over the summits of the seamounts where this species was exploited by bottom longlining from 1988 to 1991. Hauls made over slopes and plains did not allow the catch of any specimen of orange roughy (Hoplostethus atlanticus). Hard and rough bottoms on the summits and flanks of the seamounts make awkward the use of bottom trawls. HALIPRO 2 showed the high species diversity of the fauna (275 species of fish belonging to 101 families). In particular, 42 different species of shark and ray were collected of which 40% are new to science. Many samples were collected for further analysis. This survey will no doubt remain a perfect exemple of a fruitful collaboration with New Zealand.

Grandperrin R. & Richer de forges B. 1999. Programme «Monts sous-marins» (1990-2000) Bilan final. IRD, Nouméa, 49 pp.
Résumé [+] [-]Le programme «Monts sous-marins» s'est déroulé au centre IRD de Nouméa depuis 1990 sous la direction de René GRANDPERRIN. Ses objectifs étaient l'étude faunistique des pentes récifales externes, des monts sous-marins et du domaine bathyal supérieur (200-1500 m) et l'évaluation de leurs potentialités halieutiques. 32 campagnes représentant un total de 446 jours de mer ont été effectuées. 18 d'entre elles ont été consacrées à l'halieutique, 13 aux études faunistiques et une à des essais de sondeur. 1496 opérations de prélèvement ont été réalisées (445 pour l'halieutique et 1051 pour la faunistique) avec les engins suivants: casier, chalut à crevettes, chalut de fond à poissons, grand chalut de fond à poissons néo-zélandais, chalut à perche, chalut pélagique à poissons, drague épibenthique, drague à roche, drague Waren et palangre de fond. En ce qui concerne l'halieutique, les ressources des pentes externes (100-600 m) ont été étudiées en Nouvelle-Calédonie et à Vanuatu, archipel pour lequel un atlas des pêches est sous presse. Les monts sous-marins agissent comme des dispositifs de concentration de poissons pour les espèces démersales. En Nouvelle-Calédonie, ils abritent une ressource en Beryx splendens qui fit l'objet d'une exploitation commerciale. Une étude scientifique, basée sur Il campagnes, a pennis de déterminer les paramètres biologiques et dynamiques de l'espèce et de modéliser sa distribution en fonction de la profondeur. Pour la première fois, une corrélation liant la croissance d'un poisson de profondeur avec le phénomène ENSO a été établie. Des travaux de génétiques des populations sont en cours sur cette espèce. Par ailleurs, le programme «Monts sous-marins» collabora étroitement avec le programme ZoNéCo d'identification et d'évaluation des ressources marines de la zone économique de Nouvelle-Calédonie. Deux synthèses portant sur les données thonières et sur les poissons profonds furent réalisées. Un halieute participa aux campagnes de bathymétrie mettant en œuvre un sondeur multifaisceaux à bord du N.O. L'Atalante. Cinq campagnes d'exploration des ressources halieutiques profondes furent effectuées à bord du N.O. Alis à l'aide de chaluts et de palangres de fond. Elles mirent en évidence l'existence de certaines ressources jusque là ignorées des pêcheurs. Les collectes de la faune bathyale ont été réalisées dans le cadre d'opérations conjointes IRD et Muséum national d'Histoire naturelle (MNHN). L'analyse des prélèvements a été possible grâce à un réseau de taxonomistes mis en place par l'IRD (Centre de Nouméa et Antenne du MNHN) et le MNHN ; il compte 181 chercheurs appartenant à 92 institutions de 24 nations différentes, ce qui représente un effort de recherche internationale exceptionnel! Les résultats obtenus dans le Pacifique sud-ouest, et notamment en Nouvelle-Calédonie, ont révolutionné la connaissance de la biodiversité des faunes profondes. 20 volumes des Résultats des campagnes MUSORSTOM qui paraissent dans la série des Mémoires du Muséum national d'Histoire naturelle sont déjà parus (environ 10 000 pages) et un autre est sous presse. Ils traitent de plus de 4500 espèces dont plus de 1300 étaient nouvelles pour la science. 126 genres nouveaux ont été créés de même que 7 familles nouvelles. Au sein de cette étude, la Nouvelle-Calédonie apparaît comme particulièrement riche en espèces et d'une très grande originalité puisque sur-les 1619 espèces actuellement publiées, 60,7 % étaient nouvelles pour la science. Des études phylogénétiques ont été réalisées sur certains groupes zoologiques en utilisant soit des techniques de biologie moléculaire (ADN), soit des méthodes de microscopie électronique. Il s'agit des Crustacés, des Echinodermes (Crinoïdes) et des Brachiopodes, parmi lesquels plusieurs formes panchroniques ont été découvertes. L'accessibilité aux faunes de profondeurs au cours du programme «Monts sous-marins» a permis de récolter des organismes qui ont fait l'objet d'analyses par le programme de pharmacologie (Substances Marines d'Intérêt Biologique: SMIB). Deux bases de données sont directement issues des travaux du programme «Monts sous-marins». Elles concernent les données halieutiques et les données faunistiques. Les premières ont été stockées à la Structure de Gestion et de Valorisation Locale (SGVL) du programme ZoNéCo. Les secondes le sont à l'IRD. Pour chacune d'elles, une procédure de création de sites INTERNET est en cours. Le problème majeur rencontré par le programme fut la disponibilité en personnel. En effet, avec une moyenne de 6 personnes, dont un chercheur et un ingénieur d'étude à plein temps, les effectifs ne dépassèrent jamais un total de 9! Le programme disposa en moyenne de 318 kFlan, dont 40 % sur fonds IRD et 60 % sur financements extérieurs. Les financements extérieurs furent de trois types: FIDES section locale du Territoire de Nouvelle-Calédonie, programme ZoNéCo et, dans une moindre mesure, MAE. Le nombre de publications réalisées par les ressortissants du programme a été de 214, dont 139 pour lesquelles le premier auteur est un membre du programme.

Résumé [+] [-]Molecular markers allow insights into the population biology and ecology of deep-sea organisms, which are usually hardly accessible to direct observation and poorly known. Such a study was undertaken here for the deep-sea fish Beryx splendens, a species of growing interest to fisheries. B. splendens populations were sampled on seamounts and continental margins in the southwestern Pacific (New Caledonia, New Zealand, southeastern Australia) and in the northeastern Atlantic. Two hundred and fifty individuals were characterised by their single-strand DNA conformation (SSCP) of a z 360-base-pair (bp) fragment of the mitochondrial cytochrome b gene, amplified by the polymerase chain reaction (PCR). Two major SSCP haplotypes were observed in New Caledonia, a and w, whose frequencies were negatively correlated along a north-tosouth cline. All SSCP haplotypes in the total sample were sequenced on 273 bp. The phylogenetic tree of B. splendens haplotype sequences, rooted by two B. decadactylus sequences, showed that a and w belong to distinct mitochondrial clades, A and W, which are separated by z 4–6 % nucleotide divergence. Thirty individuals from New Caledonia were characterised by their DNA fingerprint from arbitrary-primed PCR. The distribution of individual-pairwise similarity indices was strongly bimodal. The larger similarity values all corresponded to comparisons within a clade (A or W) while the lower values were all between clades. Therefore, there was a strict association between the mitochondrial type and the DNA (presumably, nuclear DNA) fingerprint of an individual. Altogether, these results point to the existence of two biological species (sp. A and sp. W) within the current taxon B. splendens. No within-species differentiation was detected at the regional scale (New Caledonia). A remarkable result is that the three cytochrome b haplotypes of northeastern Atlantic B. cf. splendens sp. A were also the three commonest in the southwestern Pacific populations of this species. Such a level of homogeneity in the distribution of haplotypes suggests there is, or recently has been, gene flow at the inter-oceanic scale.

Résumé [+] [-]Une étude conjointe associant Foraminifères planctoniques et nannofossiles calcaires a été entreprise sur les sédiments pélagiques de la carotte KK97 (Figs. 1 à 3). L'examen de la nannoflore fossile avait été précédé par celui du nannoplancton vivant. Ce dernier a été réalisé à partir de prélèvements d'eau effectués par J. Blanchot de l'O.R.S.T.O;M. (Nouméa). L'objectif de cette étude conjointe était d'évaluer l'importance de la participation des organismes planctoniques dans l'élaboration du sédiment et de tester les potentialités des deux groupes dans les deux domaines suivants: la chronostratigraphie et les paléoenvironnements. La carotte a déjà fait l'objet d'études sédimentologiques auxquelles nous renvoyons le lecteur (Liu, 1988). Nous ne présenterons ici que le schéma sédimentologique interprétatif (Fig. 2) ainsi que l'illustration photographique (Fig. 3). La carotte représente une épaisseur de sept mètres. Les échantillons sont repérés par rapport aux différents tronçons et par leur profondeur (en cm) par référence au sommet de chaque tronçon. Nous rappelons cependant que la sédimentation est loin d'être continue. La carotte se présente comme 'empilement de petites séquences turbiditiques, chaque séquence se terminant par un niveau d'aspect crayeux représentant la sédimentation pélagique autochtone. Ces véritables craies sont constituées par l'accumulation de coccolithes et de Foraminifères planctoniques. C'est tout naturellement ces niveaux qui ont été prélevés et qui ont fait l'objet de la présente étude.

Résumé [+] [-]In comparison with other ecosystems, biodiversity and natural-product diversity of the New Caledonian marine ecosystem, comprising lagoons, barrier reefs, and deep waters in seamount regions, are described here phylogenetically with the aid of molecular drawings and tabulation of data. Admittedly, since the inception of these studies in 1977, the comparison is biased by selection of New Caledonian organisms on the basis of positive pharmacologically oriented bioassays. However, we show that these and other distortions must be accepted to draw any comparison on a regional basis, which, nonetheless, turn out to be useful for the progress of knowledge, particularly in directing future explorations of biodiversity in the search for new pharmacologically active metabolites.

Résumé [+] [-]La caractérisation du substrat des fonds marins est une première étape fondamentale pour la prédiction des habitats benthiques, la gestion des ressources biologiques ou encore l’inventaire des ressources minérales. Ce travail est d’autant plus essentiel lorsque l’on traite la Zone Economique Exclusive (ZEE) de Nouvelle-Calédonie considérée, à l’échelle globale, comme une des régions les plus riches en termes de biodiversité marine. Ce stage, qui a pour but de cartographier la nature des fonds de la ZEE, s’inscrit dans le cadre du projet de mise en place d’une politique de « gestion intégrée de l’Espace maritime de la Nouvelle-Calédonie ». La méthodologie employée pour répondre à cet objectif a consisté à traiter l’ensemble des données d’imagerie acoustique acquises pour la plupart au cours des campagnes ZoNéCo et à les corréler aux prélèvements disponibles. Ce travail a permis de réaliser la carte de réflectivité des fonds marins couvrant 34 % de la ZEE et la mise à jour de la base de données des prélèvements comptabilisant aujourd’hui plus de 880 échantillons. L'examen approfondi de ces nouvelles données a permis de créer une classification adaptée à la Nouvelle-Calédonie s'inspirant des normes européennes EUNIS. Au final, deux cartes ont été produites : (i) une carte présentant la dureté des fonds marins de la ZEE et (ii) une carte présentant la nature et le type de substrat de la ZEE. Ces nouveaux résultats révèlent la présence de grands ensembles sédimentaires et la découverte de nouvelles structures géologiques. Sur un plan appliqué, ce travail a amélioré la connaissance des ressources minérales de la ZEE et a permis de créer les couches d’informations utiles aux futurs travaux de prédiction des habitats benthiques marins. Il a enfin été l’occasion de dresser des préconisations visant à réduire les incertitudes et orienter les travaux futurs.

Evolution of the Glorieuses seamount in the SW Indian Ocean and surrounding deep Somali Basin since the Cretaceous. Marine Geology 427: 106202. DOI:10.1016/j.margeo.2020.106202
Résumé [+] [-]Little is known about the geological history of the Glorieuses seamount including basic information about its age and origin related to the regional evolution of the southern tip of the Somali Basin. This study focused on describing and reconstructing the long-term stratigraphic evolution of the Glorieuses seamount (SW Indian Ocean) to identify the mechanisms that have occurred through time to finally shape the emerged modern islands. Distinct terrace levels, currently submerged along the flanks of the seamount and surrounding seamounts, have already been interpreted as resulting from successive carbonate development and back-stepping episodes over the last 62 Myr. New isotopic and biostratigraphic dating on the flanks of the seamount, coupled with sequence stratigraphic interpretation of seismic profiles acquired in the adjacent basin, provide new constraints for the Late Cretaceous and Cenozoic vertical evolution of the seamount topped by carbonate platforms and sedimentation in the surrounding deep basin. Even if starved steep slopes prevent a straightforward source-to-sink continuity between the platform and the basin domains, our findings propose a consistent chronostratigraphic framework for the identified seismic markers and sequences in the deep basin, and discuss a long-term geological model that includes the main driving factors behind deposition (volcanic events, subsidence vs uplift phases, climate and hydro-dynamism changes) and their quantitative impact on the evolution of the isolated carbonate sedimentary system. Our results show that: (i) the Glorieuses volcanic seamount emerged from two successive Late Cretaceous magmatic pulses, firstly during the Turonian, then during the Maastrichtian (ii) at least two potential uplift phases are recognized during the Tertiary (Paleogene and/or the Eocene and Tortonian); (iii) basinal sedimentation recorded an abrupt change probably related to major regional hydro-dynamical changes in Late Eocene times in the Western Indian Ocean; (iv) the export of sediments from the platform towards the basin (numerous gravity flow processes) is strongly enhanced after the Mid Miocene, and is probably linked to the onset of the Asian monsoon winds and bipolar circulation. Finally, the Glorieuses seamount, although located in the vicinity of the Comoros islands, appears to have a much longer history and is geologically more comparable to the nearby Seychelles. This long-term study has enabled us to associate the Glorieuses seamount with the SSE-NNW Madagascar-Seychelles alignment rather than with the Comoro hot spot evolution.

Liu J.D. & Cotillon P. 1989. Present and recent sedimentation in the Loyalty basin along the Thio-Lifou profile (New Caledonia, Southwest Pacific). Marine Geology 87: 207-226
Résumé [+] [-]The Loyalty Basin, northeast of New Caledonia, is about 100 km wide and 2350 m deep in the transect between Thio (New Caledonia) and the island of Lifou. It is bounded to the southwest by New Caledonia and its surrounding barrier reef and to the northeast by the barrier reef of the Loyalty Ridge. Lifou Island, a raised atoll, is an emerged part of the Loyalty Ridge. The sediments cored in the Loyalty Basin during the BIOCAL mission in 1985 are bioturbated and composed of an alternation of turbidites and hemipelagites. The hemipelagites are brown -yellowish muddy oozes to calcareous muds; the turbidites are composed of sandy and silty oozes capped transitionally with muddy oozes. The hemipelagite and the T, division of the Bouma sequence have different characteristics but are not located in the core. However, they can be distinguished by carbonate composition and grain size. All the sediments originate from five sources: (1) New Caledonia (quartz, mud and heavy minerals), (2) the barrier reef (fragments of algae, madreporarian corals, foraminifera and mud of the periplatform, (3) plankton (foraminifera, coccoliths and pteropoda), (4) the bathyal community and (5) pyroclastic fragments. Turbidites, distributed in cores between Thio and Lifou, constitute a low-profile submarine fan fed by the main canyons of the slope opposite the Thio Pass. The fan developed from a rim of slumps and mud flows located near the base of the slope. The fan extends 50 km toward the northeast as far as the tectonic Levi Ridge. The hemipelagites are predominant beyond this ridge. The modern sedimentation rate is 60 m/Ma on the proximal fan. It is 4- 6 times less than the average sedimentation rate calculated for the period since the origin of the basin in the late Eocene.

Résumé [+] [-]Two new deep water Coelorinchus species were captured during a joint Australia/New Zealand marine fauna survey of the West Norfolk and South Norfolk Ridges and south Lord Howe Rise in May-June 2003. Coelorinchus Osipullus sp. Nov. Is similar to the Australasian C. celaenostomus McMillan and Paulin and had been mistakenly identified as such in French collection surveyx off New Caledonia and the Loyalty Islands, but the new species has pale to dusky lips and mouth compared to the intense black markings of C. celaenostomus. It is also very similar to C. sheni Chiou, Shao, and Iwamoto from Taiwan, but has shorter and narrower snout and blackish gums compared to the pale gums of C. sheni. Coelorinchus obscuratus sp. Nov. Is most similar to C. occa (Goode and Bean) from the western North Atlantic, but the latter has a larger orbit, lacks a blackish orbital rim, and has much more coasely spinnulated scales.

Résumé [+] [-]Sunken woods are abundant in deep oceanic environments, housing a huge faunal diversity. Studies on that substrate firstly focused on the associated organisms, but since a few years, identification of wood is a further aim. The purpose is to appreciate its degradation state, diversity, geographical origin and to identify specific associations between colonizing organisms and substrates. The first determinations were made on sunken woods from Taiwan/Philippines, the Vanuatu Archipelago, and the Mediterranean Sea. Samples' identification was based on histological studies. Different preparation techniques were used, depending on their degradation state. Detailed anatomy descriptions were made and compared to the native flora and the introduced species. Wood samples were well preserved. Diversified species were encountered, seemingly originating from local floras. In situ settlements of known wood species will enhance the knowledge of degradation and colonization degrees.

Résumé [+] [-]When deposited in marine sediments, sunken wood and large animal remains can undergo sufficiently steady decay for oxygen to be depleted, attracting anaerobic living forms. Chemosynthetically living communities have recently been identified around whale skeletons and sunken woods. The phylogenetic resemblance and overlap in species of metazoans living in these habitats with those of highly reduced environments like hydrothermal vents and vent seeps has led to the hypothesis that deep-sea organic rich matter deposits could play a major role in the adaptation and evolution of chemoautotrophic communities at the ocean basin. Until present little attention has been paid to the free-living microbial diversity and activities in large organic falls like sunken woods and whale bones. In this communication we outline a series of methods to quantitatively study microbial biodiversity and degradation processes in sunken wood. Cellulose is the most abundant component of plant material and it can only be degraded by fungi and bacteria. We present results from cellulolytic activities in a long-term ex-situ experiment on samples from naturally and experimentally immersed sunken wood. We also have developed methods to quantitatively measure microbial cell numbers in wood chips. Further studies at the molecular level in combination with the methods reported here will broad our narrow knowledge on the microbial biofilms that develop on and within sunken woods and give clues on the ecological importance of these deep-sea organic islands.

Résumé [+] [-]Les fluctuations conjointes du niveau marin de la mer et du développement récifal sont enregistrées par la sédimentation quaternàire dans les domaines de périplate-forme et de bassin. Telle est la conclusion d'études menées surtout aux Bahamas et dans leurs environs immédiats (Boardman et al., 1986 ; Kier et Pilkey, 1971 ; Droxler et al., 1988). Dans cette région les sédiments profonds contiennent 70 à 90% de carbonates provenant des plates-formes carbonatées et de leurs récifs (Boardman et Neumann, 1984), les pourcentages dépendant du développement des bioconstructions soumises aux oscillations marines des périodes glaciaires et interglaciaires. En période froide et de bas niveau marin, le récif émerge et subit une altération météoritique, ce qui se traduit par une -réduction du flux détritique carbonaté dans les bassins, et, par conséquent, par de faibles teneurs relatives en carbonates totaux et en aragonite. En période chaude, la remontée du niveau de la mer favorise la croissance du récif qui devient alors une source importante pour le détritisme carbonaté. On observe donc un relèvement des pourcentages en carbonates totaux et en aragonite dans les sédiments. Ce mécanisme a été retrouvé dans les bassins des Loyauté et de Nouvelle-Calédonie, mais quelque peu modulé par le contexte mixte, carbonaté et silicoclastique, de la sédimentation, différant sensiblement de celui, purement carbonaté, des Bahamas. La carotte 21, prélevée au pied de la pente SW de la Nouvelle-Calédonie (Fig. 1), a permis d'établir des corrélations entre la succession récifale quaternaire traversée par forage au Sud-Ouest de la Nouvelle-Calédonie (Coudray, 1976) et l'évolution verticale de divers composants sédimentaires. Ce principe de corrélation a été ensuite étendu aux forages du bassin des Loyauté.

Résumé [+] [-]Les campagnes BIOCAL et BIOGEOCAL ont permis d'effectuer de nombreux prélèvements de sédiments récents dans le bassin des Loyauté à l'aide d'un carottier Usnel (KG) et d'un carottier Kullenberg (KK) (Fig. 1). La plupart d'entre eux se situe en bas des pentes et au centre du bassin. La partie haute des pentes a été rarement échantillonnée, mais en revanche, a fait l’objet d'observations directes lors de la campagne CALSUB (cf. Rio et al., ce volume). Au SW, le bassin est bordé par un récif barrière discontinu isolant un lagon relativement profond, tandis qu'au NE, l'atoll soulevé de Lifou ne possède que des récifs frangeants et un étroit palier littoral avant l'amorce du talus très pentu (cf. Roux, ce volume). Les résultats de la campagne BIOCAL (Cotillon et al., 1989b) ont indiqué que la sédimentation récente depuis 30.000 ans est constituée de boues hémipélagiques fines interrompues par des niveaux bioclastiques resédimentés. Nous présentons ici une analyse plus complète de la distribution des composants carbonatés dans les sédiments profonds, afin d'en cerner les différentes origines et d'apporter des informations supplémentaires sur la dynamique sédimentaire.

Résumé [+] [-]The University of the Philippines (UP) Biology Invertebrate Museum has recently completed the curation of its accessioned collections of invertebrates. This paper reports on the availability of the said collections to the community of researchers studying invertebrates. The accessioned collections were assessed in terms of their taxonomic scope, geographical range, and chronological breadth. A total of 4,238 accessioned specimens are in the Museum, which is composed of 1,108 non-insectan arthropods, 1,149 cnidarians, 178 echinoderms, and 1,803 mollusks. The insect specimens, all of which do not have any accession numbers, are yet to be curated. A total of 1,185 species belonging to 621 genera are found in the collections. The Museum’s sampling activities were greatest in the western part of the Philippines, specifically in Puer to Galera, Oriental Mindoro. Much of the Eastern regions in the Philippines are yet to be sampled, particularly the terrestrial habitats. Prolific museum contributors include Francisco Nemenzo, Sr. (709 specimen lots), Neon Rosell (327 specimen lots), and Fernando Dayrit (233 specimen lots). At present, plans for collection expansion is underway, to encourage collaborative research with other natural history museums.

Deep, diverse and definitely different: unique attributes of the world's largest ecosystem. Biogeosciences 7(9): 2851-2899. DOI:10.5194/bg-7-2851-2010
Résumé [+] [-]The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet. This review describes these patterns and processes, from geological settings to biological processes, biodiversity and biogeographical patterns. It concludes with a brief discussion of current threats from anthropogenic activities to deep-sea habitats and their fauna. Investigations of deep-sea habitats and their fauna began in the late 19th century. In the intervening years, technological developments and stimulating discoveries have promoted deep-sea research and changed our way of understanding life on the planet. Nevertheless, the deep sea is still mostly unknown and current discovery rates of both habitats and species remain high. The geological, physical and geochemical settings of the deep-sea floor and the water column form a series of different habitats with unique characteristics that support specific faunal communities. Since 1840, 28 new habitats/ecosystems have been discovered from the shelf break to the deep trenches and discoveries of new habitats are still happening in the early 21st century. However, for most of these habitats the global area covered is unknown or has been only very roughly estimated; an even smaller - indeed, minimal - proportion has actually been sampled and investigated. We currently perceive most of the deep-sea ecosystems as heterotrophic, depending ultimately on the flux on organic matter produced in the overlying surface ocean through photosynthesis. The resulting strong food limitation thus shapes deep-sea biota and communities, with exceptions only in reducing ecosystems such as inter alia hydrothermal vents or cold seeps. Here, chemoautolithotrophic bacteria play the role of primary producers fuelled by chemical energy sources rather than sunlight. Other ecosystems, such as seamounts, canyons or cold-water corals have an increased productivity through specific physical processes, such as topographic modification of currents and enhanced transport of particles and detrital matter. Because of its unique abiotic attributes, the deep sea hosts a specialized fauna. Although there are no phyla unique to deep waters, at lower taxonomic levels the composition of the fauna is distinct from that found in the upper ocean. Amongst other characteristic patterns, deep-sea species may exhibit either gigantism or dwarfism, related to the decrease in food availability with depth. Food limitation on the seafloor and water column is also reflected in the trophic structure of heterotrophic deep-sea communities, which are adapted to low energy availability. In most of these heterotrophic habitats, the dominant megafauna is composed of detritivores, while filter feeders are abundant in habitats with hard substrata (e. g. mid-ocean ridges, seamounts, canyon walls and coral reefs). Chemoautotrophy through symbiotic relationships is dominant in reducing habitats. Deep-sea biodiversity is among of the highest on the planet, mainly composed of macro and meiofauna, with high evenness. This is true for most of the continental margins and abyssal plains with hot spots of diversity such as seamounts or cold-water corals. However, in some ecosystems with particularly "extreme" physicochemical processes (e.g. hydrothermal vents), biodiversity is low but abundance and biomass are high and the communities are dominated by a few species. Two large-scale diversity patterns have been discussed for deep-sea benthic communities. First, a unimodal relationship between diversity and depth is observed, with a peak at intermediate depths (2000-3000 m), although this is not universal and particular abiotic processes can modify the trend. Secondly, a poleward trend of decreasing diversity has been discussed, but this remains controversial and studies with larger and more robust data sets are needed. Because of the paucity in our knowledge of habitat coverage and species composition, biogeographic studies are mostly based on regional data or on specific taxonomic groups. Recently, global biogeographic provinces for the pelagic and benthic deep ocean have been described, using environmental and, where data were available, taxonomic information. This classification described 30 pelagic provinces and 38 benthic provinces divided into 4 depth ranges, as well as 10 hydrothermal vent provinces. One of the major issues faced by deep-sea biodiversity and biogeographical studies is related to the high number of species new to science that are collected regularly, together with the slow description rates for these new species. Taxonomic coordination at the global scale is particularly difficult, but is essential if we are to analyse large diversity and biogeographic trends. Because of their remoteness, anthropogenic impacts on deep-sea ecosystems have not been addressed very thoroughly until recently. The depletion of biological and mineral resources on land and in shallow waters, coupled with technological developments, are promoting the increased interest in services provided by deep-water resources. Although often largely unknown, evidence for the effects of human activities in deep-water ecosystems - such as deep-sea mining, hydrocarbon exploration and exploitation, fishing, dumping and littering - is already accumulating. Because of our limited knowledge of deep-sea biodiversity and ecosystem functioning and because of the specific life-history adaptations of many deep-sea species (e. g. slow growth and delayed maturity), it is essential that the scientific community works closely with industry, conservation organisations and policy makers to develop robust and efficient conservation and management options.

Résumé [+] [-]Sampling cruises of bathyal benthos in New Caledonia for the years 1993-94 (BATHUS 1-4, SMIB 8, HALIPRO 1). In 1992 and 1993, several oceanographic cruises (BATHUS 1-4) were carried out with the aim of improving the inventory of the benthic fauna of the outer slopes around New Caledonia. On the basis of these results, another cruise (HALIPRO 1) was devoted to the sampling of fishes on slopes suitable for trawling, down to depths of 1100 m. In addition, the SMIB (Substances Marines d'Intérêt Biologique) research program was continued, with a new cruise - SMIB 8 - collecting deepwater invertebrates for experimentation. All of these cruises took place on board the R.V. "Alis" of the Nouméa Research Station (ORSTOM). The present paper gives an account of the fauna collected, the geomorphological characteristics of the zones explored, and an indication of particular studies on the material collected. The latter include population genetics (particularly of Brachiopoda and decapod Crustacea) and crustacean phylogeny. An appendix is provided, giving a list of stations sampled by the various cruises and their general characteristics.

Résumé [+] [-]The MUSORSTOM 9 cruise was carried out in the Marquesas Archipelago from 18 August to 11 September 1997. 168 samples by dredging and trawling were made in the upper-bathyal zone and in the circalittoral depths, on the slope ofthe islands and on the top of the Dumont d'Urville Seamount. A terrace with a gentle slope is surrounding each island. Deeper than 100 meters the slope is very steep with from time to time terraces between 400 and 600 meters deep. The benthic fauna of this remote archipelago isolated in the Central Pacific is remarkably poor in all the groups.

Résumé [+] [-]The BORDAU 1 cruise was carried out in the Fijian Archipelago from 22 February to 14 March 1999 on board of R.V. "Alis". A total of 118 samples were made by dredging and trawling in the upper bathyal zone and in the circalittoral depths of the islands and on the seamounts in the Lau Ridge. The upper part of the slope to 600 m consists of hard bottoms and deeper muddy bottoms with pumice. In some islands particularly isolated (Vanua Balavu, Yacata, Aiwa and Yagasa), the landsnails were sampled.

Résumé [+] [-]The MUSORSTOM 10 cruise, using the R.V. "Alis", was carried out in the Fijian Archipelago during 5-19 August 1998. A total of 82 samples were collected by dredging and trawling from the upper bathyal zone and in the circalittoral depths, on the outer reef slopes of Vitu Levu and from Bhgh Water. The bottom of Bligh Water is muddy and covered with pumice stones. Hard bottoms were sampled in the Beqa Channel. The invertebrate biodiversity of the benthic communities sampled is much lower than those sampled from the New Caledonian area, especially sessile epifaunal groups like sponges, stylasterine hydrocorals (Cnidaria, Stylasterina) and crinoids.

Résumé [+] [-]L'observation directe, à l'aide de la soucoupe plongeante CYANA, des pentes bathyales néocalédoniennes révèle l'ampleur des phénomènes d'érosion (cf. Vanney, ce volume) qui entaillent le substratum géologique. Pour la première fois nous avons eu accès aux affleurements. Bien que l'échantillonnage de roches soit très réduit, une description même sommaire des unités géologiques rencontrées et de leurs relations est utile compte tenu de l'état actuel des connaissances. Les produits de l'érosion vont s'accumuler dans le bassin des Loyauté. Ils s'ajoutent aux apports planctoniques, aux éléments biogènes autochtones ou subautochtones, et aux sédiments issus de la plateforme pour constituer un mélange de matériaux de nature, d'origine et d'âge variés (cf. Lambert et al., ce volume, Fig. 1). Nous tenterons ici de cerner ces différences d'origine et d'apprécier leur importance. Nous décrirons aussi quelques modes de transport vers le bassin.

Résumé [+] [-]During the CALSUB cruise, bathyal environments were explored off the New Caledonia corallian platfdrms (southwestern Pacific). Green algae were observed down to a depth of 1 IO m, and red algae down to 145 m. Algal blocks, pebbles and sands contribute to sedimentation to a depth of 400 m and beyond, and are mixed with autochthonous fossils and bioclasts produced by bathyal benthos. Epibathyal fauna suggests similarities with Jurassic and Cretaceous fauna of Tethyan margins (Nautilus, pleurotomarian gastropods, sponges, brachiopods and crinoids…). Richness and abundance of the benthos are the highest in areas where currents are frequent between 300 m and 700 m (sometimes 10 to 20 terebratulid brachiopods per m2 or dense populations of echinoderms entirely covering the substrate). Such currents induce erosion of' substrate or bioclastic accumulations. Biocorrosion seems to be very active in erosion processes, especially on hard grounds. Burrows and traces show the importance of sediment bioturbation on slopes. The occurrence on bathyal slope of some taphonomic processes previously known from geological series and generally considered as closely related lo shallow-water environments should be emphasized.

Résumé [+] [-]La Nouvelle-Calédonie s'étend entre 20 et 23° S selon une orientation NW-SE (Fig. 1 et 2). Elle correspond à la partie émergée du segment nord de la ride de Norfolk et appartient à la plaque australienne qui, vers l'Est, plonge sous la plaque pacifique au niveau de la fosse des Nouvelles-Hébrides en induisant un bombement de la lithosphère à l'origine de l'émersion des Iles Loyauté. La Grande Terre, prolongée au SE par l'Ile des Pins, est bordée au SW par le bassin de Nouvelle-Calédonie, d'une profondeur comprise entre 3000 et 3500 m, et au NE par le bassin des Loyauté dont la profondeur, d'environ 2000 m au SE, s’accroît jusqu'à plus de 3000 m au NW . Sa plateforme externe est limitée par un récif barrière isolant un lagon de largeur variable. Les trois principales îles de l'archipel des Loyauté sont alignées parallèlement à la Grande Terre : au SE Maré, puis Lifou et au NW Uvéa.

Résumé [+] [-]The CALSUB cruise took place in 1989 off the coast of New Caledonia. The diving saucer Cyana enabled the exploration of the bathyal environment from the edge of the coral platform down to a depth of 3000 m. In this paper an account is given of how the study was carried out, along with the material gathered during the course of the study which may be consulted (in particular the photographs and the videos). The various sectors explored, and the principal observations made are discussed. Apart from the wide diversity of ecological niches observed, what makes this sector of the Pacific Ocean original, is the existence of bathyal benthic communities rich in "living fossils", giving us an idea of the fauna which populated the Tethys Ocean during the Mesozoic. The use of the Cyana diving saucer allowed direct observation of the nature of the sea beds and the associated fauna, in particular of rocky slabs, and environments affected by deep currents, where fields of hydraulic bioclastic dunes develop along fault scarps covered with dense populations dominated by Echinoderms. We were able to establish the bathymetrical distribution of the bathyal populations.

Résumé [+] [-]Seamounts are unique habitats for the seep-sea megabenthos. Several distinctive environmental conditions, such as limited spatial extent, geographic isolation, swift currents, localized upwelling and circulation cells create environments favorable for the establishment of diverse benthic assemblages. Relatively large suspension feeders such as corals, sponges and crinoids, can dominate the biomass of these assemblages and form structural habitat for a diversity of smaller, mobile species. The benthos contains species with apparently limited geographic distributions (endemics) and archaic species throught to have become extinc ('living fossils'). Seamounts rise well above the ocean floor and thus form relatively shallow habitat available for bathyal species above the surrounding abyssal seafloor. Growth of seamount invertebrates can be extraordinarly slow and they often have very long life spans. These life-history traits make the seamount benthos highly vulnerable to destructive bottom trawling. The prominence of suspension feeders suggests a simple trophic web, but in fact, benthic food webs are complex: food-chain lengths and trophic architecture rival other marine ecosystems in both shallow and deep settings. The geographic isolation of seamounts has frequently been likened to oceanic islands, where species differences among seamounts can be very high. Yet, seamount populations may not necessarely be genetically isolated if they produce larvae capable of long-distance dispersal. The fauna of seamounts is poorly documented, and the structure of whole assemblages is known from only a limited number of seamounts worldwide, partly as a consequence of dwindling resources and expertise in taxonomy. Lack of basic ecological knowledge impedes the development of global, integrated structural and functional frameworks concerning seamount benthos.

Résumé [+] [-]Le modelé sous-marin est l'ensemble des formes dont la définition fait appel au façonnement par des processus morphogéniques (ceux-ci correspondent aux modalités d'action des divers agents sous-marins). Son étude n'a pas encore la place qu'elle pourrait occuper dans les recherches océanographiques. Le façonnement des versants sous l'action des divers processus reste mal connu, en dépit du nombre et de la qualité des observations faites au cours de plusieurs centaines de plongées en submersible. A l'ordinaire, les formes sont présentées de manière générale, selon la nature et l'agressivité supposées des processus responsables. Plus rarement intervient une distinction selon les provinces (dites "physiographiques"), l'étagement, l'exposition, la déclivité des versants. A cet égard, la province de la pente continentale (ou insulaire), c'est-à-dire le milieu bathyal des biologistes, est sans doute l'un des espaces sous marins parmi les plus favorables à l'étude du modelé, en raison des contrastes de topographie et de situation qu'elle présente (Bouma, 1979). Pour d'autres raisons, le glacis continental (ou insulaire) serait l'autre province propice. Depuis peu, une différenciation zonale a été introduite, au moins pour les étages supérieurs des marges (Vanney, 1977, pour ce qui concerne les platesformes continentales). La zone froide a été la première et la plus aisément individualisée, à cause de la spécificité de ses formes et de ses dépôts (Vanney et Dangeard, 1976 ; voir aussi pour les étages supérieurs des marges: Bornhold et Guilcher, 1984)). A notre connaissance, peu a été fait en ce sens sur la nuance. Tropicale du modelé sous-marin, en dehors de ses aspects strictement sédimentaires. Sur cette dimension zonale du problème, la campagne CALSUB s'est révélée propice à un enrichissement sensible de nos connaissances dans le cas particulier de l'environnement corallien. Du modelé, la brève présentation qui suit ne saurait donner un tableau complet des faits observés sur les versants sous-marins de l'ensemble de l'archipel néocalédonien. C'eût été la plus délicate des entreprises, exigeant non seulement la collaboration de plusieurs disciplines (outre les biologistes et les géologues) : des océanographes physiciens, des géochimistes, des sédimentologistes, se livrant à une étude répétée et approfondie de plusieurs situations topographiques types, doublée de prises suivies de prélèvements (eau, sol) aux fins de mesures. Cela fut réalisé pour le périmètre HEBBLE, choisi sur le glacis continental atlantique de l'Amérique du Nord (Nowell et Hollister, 1985). Rien de tout cela n'était envisagé dans le cas d'une campagne de plongées dont le programme était autre. Cependant, les formes, les paysages même, rencontrés au cours des vingt-deux immersions, ont apporté un tel lot d'observations nouvelles qu'il a paru opportun d'en faire le recensement, le regroupement appuyés sur une ébauche d'interprétation et des comparaisons avec d'autres secteurs visités par l'auteur (Méditerranée, Atlantique). L'inventaire morphologique qui suit ne peut être que partiel compte tenu de l'exiguïté de l'aire prospectée (entre 100 et 3000 m). La distribution des plongées en quatre secteurs (Fig. 1) a toutefois aidé à pallier cette restriction.

Résumé [+] [-]We report the discovery during CALSUB cruise of submarine features, including series of pillars and microtables cldsely related to Fe-Mn deposits entrapped into a soft or weakly cemented hemipelagic ooze, from a Tertiary volcanic ridge setting off New Caledonia. Such features seems to be closely related to hydrothermal circulation through calcareous sedimentation, as a consequence of the volcanic activity of Loyalty ridge during the Miocene time.

Résumé [+] [-]The benthic foraminifers fauna from the Loyaulty Basin (New-Caledonia) is studied through a series of samples obtained in several cores along a transection between Thio and Lifou Island, as well as from a few comparative stations (BIOCAL cruise - 1985 - R/V Jean Charcot). Despite a low number of specimens (in relation to the planktonic ones) the benthic foraminifers from the upper layer of the sediment show a large diversity : more than 200 taxa which were put together into 20 groups for the analysis. Their distribution and abundance in the 19 analyzed stations show that some of them are preferentially located on the slopes although others mainly occur on the deeper parts of the basin. The demonstrate conveying of sediments between these areas. A quantitative approach shows that these conveyings are controled by the submarine topography.

Résumé [+] [-]L'essentiel de ce chapitre a déjà fait l'objet de contributions antérieures (Vincent, 1986 ; Vincent et Laurin, 1988), mais une illustration exhaustive de la microfaune manquait. Avec la contribution consacrée aux organismes planctoniques, c'est l'ensemble de la microfaune et la nannoflore qui sera ainsi figuré. L'analyse du plancton portait sur un seul site de prélèvements. Ce choix reposait sur le peu de sensibilité de ces organismes aux variations environnementales locales (topographie par exemple) en comparaison de leur capacité plus importante à enregistrer les variations de plus grande envergure (climatiques) au cours du temps. A l'opposé, l'examen de la microfaune benthique s'est effectué à partir de prélèvements régulièrement répartis suivant une transversale au bassin des Loyauté. Entouré de plate-formes coralligènes, le bassin des Loyauté constitue un bon modèle d'environnêment bathyal situé en contrebas d'édifices récifaux. Une série de levés cartographiques réalisés par sondeurs multifaisceaux (voir contributions précédentes) a permis d'établir avec précision la topographie sous-marine. L'objectif de cette étude, déjà évoqué précédemment, était: (1) d'analyser la répartition des Foraminifères benthiques de la partie superficielle des sédiments actuels. (2) de préciser les éventuelles relations entre cette répartition et les facteurs sédimentologiques reconnus. (3) d'identifier les microfaunes allochtones provenant des plates-formes récifales. Sur toute la rone ayant fait l'objet de prélèvements les sédiments sont homogènes, composés de boues de couleur beige essentiellement carbonatées (80 %) et d'argile fine. Les éléments biogènes d'origine planctonique sont nettement dominants (Foraminifères, Ptéropodes, Radiolaires).

Résumé [+] [-]The Minister for Environment and Heritage, on 26 september 2001, announced plans to access the conservation values of 11 unique marine areas in Australia Commonwealth waters (DEH 2004 a). Two were assessed within the framework of the South East Regional Marine Planning process in 2002 ( Butler et al 2002 a and b). The Norfolk Island Seamounts area (NISA) is the third, and was nominated for assessment based on an expectation that it supported a high diversity of endemic fauna. CSIRO was asked to provide a summary of thee relevant and available data for the area, together with expert opinions, and come to a balanced conclusion regarding the questions "Does the NISA possess biodiversity values worthy of protection?"

Zezina O.N. 1997. Biogeography of the Bathyal Zone. Advances in Marine Biology 32: 389-426
Résumé [+] [-]The bathyal zone lies along the slopes of continents and on seamounts and underwater rises. It extends from the edge of the shelf to the beginning of the abyss and is a substantial part of the ocean, being larger than the shallow shelf zone, including the sublittoral. Some taxa of benthic animals attain their optimal number of species and abundance in the bathyal zone. The distribution of the bathyal fauna is described on the basis of groups of species with comparable geographical range, termed geographic faunistic elements or types of range. The Brachiopoda, which have been thoroughly studied from a large database of samples and records, are used to establish clear biogeographical patterns in the bathyal zone of the world ocean. There are depth-related changes within the limits of the bathyal zone: the number of species; the number of geographic faunistic elements; and the number of latitudinal (climatic) faunistic belts diminish with increasing depth. Correspondingly, there is a reduction in number of faunistic provinces. The simplification in biogeographic structure of bottom fauna down the slopes is in accordance with the simplification in the structure of the water masses that are in contact with the bottom along the slopes. Food supply is also an important factor related to depth distribution of the macrobenthic animals. The basic biogeographical divisions of the bathyal zone become asymmetric under the influence of the unequal distribution of land and water masses on the globe, and in relation to oceanic gyres that cause differences in productivity on the eastern and western sides of the oceans. This inequality results in faunistic differences especially in the number of species in different taxa. The bathyal zone may have acted as a reserve of species for recolonization of the shelves and the abyss between periods of global changes in climate. Partly related to this, the bathyal zone contains many relict species, some of which are the most primitive extant members of their groups. The function of the bathyal zone as a reserve of species is challenged by the consequences of commercial exploitation of the non-sustainable fish and shellfish populations on the upper part of the continental slope and on seamounts.

Résumé [+] [-]The bathyal zone lies along the slopes of continents and on seamounts and underwater rises. It extends from the edge of the shelf to the beginning of the abyss and is a substantial part of the ocean, being larger than the shallow shelf zone, including the sublittoral. Some taxa of benthic animals attain their optimal number of species and abundance in the bathyal zone. The distribution of the bathyal fauna is described on the basis of groups of species with comparable geographical range, termed geographic faunistic elements or types of range. The Brachiopoda, which have been thoroughly studied from a large database of samples and records, are used to establish clear biogeographical patterns in the bathyal zone of the world ocean. There are depth-related changes within the limits of the bathyal zone: the number of species; the number of geographic faunistic elements; and the number of latitudinal (climatic) faunistic belts diminish with increasing depth. Correspondingly, there is a reduction in number of faunistic provinces. The simplification in biogeographic structure of bottom fauna down the slopes is in accordance with the simplification in the structure of the water masses that are in contact with the bottom along the slopes. Food supply is also an important factor related to depth distribution of the macrobenthic animals. The basic biogeographical divisions of the bathyal zone become asymmetric under the influence of the unequal distribution of land and water masses on the globe, and in relation to oceanic gyres that cause differences in productivity on the eastern and western sides of the oceans. This inequality results in faunistic differences especially in the number of species in different taxa. The bathyal zone may have acted as a reserve of species for recolonization of the shelves and the abyss between periods of global changes in climate. Partly related to this, the bathyal zone contains many relict species, some of which are the most primitive extant members of their groups. The function of the bathyal zone as a reserve of species is challenged by the consequences of commercial exploitation of the non-sustainable fish and shellfish populations on the upper part of the continental slope and on seamounts.
