Program 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
Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]Ten species of Sipunculans collected during a survey of the bathyal fauna of seas off the coast of the Philippines (cruises ESTASE 2 and MUSORSTOM 3) and near New Caledonia (cruises BIOCAL and MUSORSTOM 4) are described and identified. The commonest species in the Philippine collection was Sipunculus robustus and in the New Caledonian Nephasoma diaphanes and Onchnesoma magnibathum. No new species are recorded. Only two species of Echiurians were collected ; the specimens were unfortunately in too poor a state for precise identification.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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. A key is included to identify all the species in the genus. An appendix is also included to clarify the publication dates of Stefano delle Chiaje papers on marine invertebrates.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]An efficient protocol to identify and describe species of Myzostomida is outlined and demonstrated. This taxonomic approach relies on careful identification (facilitated by an included comprehensive table of available names with relevant geographical and host information) and concise descriptions combined with DNA sequencing, live photography, and accurate host identification. Twenty-one new species are described following these guidelines: Asteromyzostomum grygieri n. sp., Endomyzostoma scotia n. sp., Endomyzostoma neridae n. sp., Mesomyzostoma lanterbecqae n. sp., Hypomyzostoma jasoni n. sp., Hypomyzostoma jonathoni n. sp., Myzostoma debiae n. sp., Myzostoma eeckhauti n. sp., Myzostoma hollandi n. sp., Myzostoma indocuniculus n. sp., Myzostoma josefinae n. sp., Myzostoma kymae n. sp., Myzostoma laurenae n. sp., Myzostoma miki n. sp., Myzostoma pipkini n. sp., Myzostoma susanae n. sp., Myzostoma tertiusi n. sp., Protomyzostomum lingua n. sp., Protomyzostomum roseus n. sp., Pulvinomyzostomum inaki n. sp., and Pulvinomyzostomum messingi n. sp.

Bitner M.A. 2006. First Record of Brachiopods from the Marquesas Islands, French Polynesia, South Central Pacific. Pacific Science 60(3): 417-424
Abstract [+] [-]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.

Abstract [+] [-]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.

Earth and Environmental Science Transactions of the Royal Society of Edinburgh 98(3-4). DOI:10.1017/S1755691008075142
Abstract [+] [-]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
Abstract [+] [-]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

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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'.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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 .

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Skythrenchelys n.gen. Differs from other myrophine ophichthids in the condition of its gill openings (moderately elongate and below lateral midline), dentition (large, conical and uniserial), posterior nostril (entirely outside mouth), and other characters. Skythrenchelys zabra n.sp., the type species, is described from India, the Philippines, Indonesia and northern Australia; S. lentiginosa n.sp. Is described from the Red Sea. 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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

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.

Abstract [+] [-]A new species of lanternshark, Etmopterus lailae (Squaliformes: Etmopteridae), is described from the Northwestern Hawaiian Islands, in the central North Pacific Ocean. The new species resembles other members of the “Etmopterus lucifer” clade in having linear rows of dermal denticles, and most closely resembles E. lucifer from Japan. The new species occurs along insular slopes around seamounts at depths between 314–384 m. It can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including a longer anterior flank marking branch, arrangement of dermal denticles on the ventral snout surface and body, flank and caudal markings, and meristic counts including number of spiral valve turns, and precaudal vertebrate. A key to species of the Etmopterus lucifer-clade is included.

Abstract [+] [-]A new species of lanternshark, Etmopterus brosei sp. nov. (Squaliformes: Etmopteridae), is described from the southeastern Atlantic and southwestern Indian oceans. The new species resembles other members of the Etmopterus lucifer Jordan & Snyder, 1902 clade in having linear rows of dermal denticles, and most closely resembles the conspecific E. sculptus Ebert, Compagno, & De Vries, 2011 from the southeastern Atlantic and southwestern Indian oceans. The new species is fairly common along the upper continental slopes off South Africa, Mozambique, and seamounts along the Madagascar Ridge, including Walters Shoal, in 480–1200 m depth. It can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including the arrangement of flank and caudal markings, shape and size of flank marking, the arrangement of dermal denticles along the body, and the presence of dermal denticles on the dorsal fin bases. A revised key to the Etmopterus lucifer clade is provided.

Faliex E., Tyler G. & Euzet L. 2000. A New Species of Ditrachybothridium (Cestoda: Diphyllidea) from Galeus sp. (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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]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.

Swath-Mapping and Related Deep-Sea Trawling in the Southeastern Part of the Economic Zone of New Caledonia, in Séret B. & Sire J.(Eds), Proceeding 5th Indo-Pacific Fisheries Conference, Nouméa: 459-468
Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]Caesio xanthalytos, a new species of fusilier, closely related to Caesio caerulaurea Lacepède 1801, is described from several specimens from various localities on the east coast of Africa, and from southern Madagascar. While very similar in colour pattern to C. caerulaurea, its lateral line lies within a dominant, composite yellow stripe, whereas in C. caurulaurea the lateral line lies immediately below the yellow stripe. The two species also differ in the number of lateral-line scales, the modal number of pectoral-fin rays, in the form of the nuchal scale patch, and genetically. The new species has been observed to school with C. caerulaurea and with C. varilineata Carpenter 1987. The ranges of several species of Caesio and Pterocaesio and of Dipterygonotus balteatus and Gymnocaesio gymnoptera are extended to localities on the South African east coast.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Seven specimens (106- 180 mm in standard length) of the sand whiting Sillago caudicula Kaga, Imamura & Nakaya, 2010 previously known only from the type specimens from Oman, were collected from the southeast coast of Madagascar. Thesenew specimens represent the first record of the species from Madagascar and the southern hemisphere. Comparisons in meristic and morphometric characters with the four type specimens from Oman, as well as with the five other species in the subgenus Sillago, allowed their clear identification using the following combination of characters: small head (28.6-30.1% SL), 35-6 total vertebrae, fused or narrowly separated first and second hypurals, fused third and fourth hypurals, and 9-11 dusky spots on midline of body.

Abstract [+] [-]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).

Abstract [+] [-]Eight species of benthopelagic synaphobranchid eels (Synaphobranchidae, Synaphobranchus affinis, S. brevidorsalis, S. oregoni, Diastobranchus capensis, Haptenchelys texis, Meadia abyssalis, Dyssomina rugoso, and Atroctodenchelys robinsorum sp. nova) were collected during MUSORSTOM cruises in 1985- 1986 and 1994-1999 off New Calcdonia and adjacent underwater rises. Descriptions are given for the two monotypic genera Haptenchelys and Atractodenchelys, previously known only from the North Atlantic and thus recorded for the first time in the Pacific, and two new species, M. abyssallis and D. rugosa, for the first time recorded in the south western Pacific. A description of the new species, A. robinsorum sp. nova, is provided based on three specimens collected in the mesobenthic zone off Chesterfield and Vanuatu Islands. The new species is distinct from its Atlantic counterpart A. phrix by the greater number of vertebrae ( 186-199 vs. 16X-172), greater number of vomcrine tceth (7-8 vs. 5), greater number of pores in supraorbital and infraorbital canals, and lower number of pores in prcopcrcular-mandibular canal.

Abstract [+] [-]The results are presented of a study of the collection of congrid (18 species) and nettastomatid (4 species) eels collected by the MUSORSTOM and other expeditions on the underwater rises and island slopes in the western tropical part of the Pacific Ocean. The following new species were described: three species of the genus Ariosoma (A. sereti and A. multivertebratum from the waters of the Marquesas Islands and A. sazonovi from the waters of the Philippines), two species of the genus Gnathophis ( G. neocaledoniensis from New Caledonia and G. asanoi from the Philippines), and one species each from the genera Parabathymyrus (P fijiensis from the Fiji Islands), Congriscus (C. marquesaensis from the Marquesas Islands), Acromycter (A. longipectoralis from the waters of New Caledonia), Blachea (B. longicaudalis from Fiji and New Caledonia), and Saurenchelys (S. taiwanensis from the waters of Taiwan). The validity of Ariosoma howensis (McCulloch & Waite), Gnathophis heterognathos (Bleeker), and Macrocephenchelys brevirostris (Chen & Weng) is confirmed. For the first time, C. maldivensis, P adenensis, and D. polystigmatus, known earlier only by occurrences in the Indian Ocean, were recorded in the western part of the Pacific Ocean.

Abstract [+] [-]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.

Abstract [+] [-]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).

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
Abstract [+] [-]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.

Abstract [+] [-]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.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Five species of the samarid genera Plagiopsetta and Samaris (Samaridae), in Marshall B.A. & Richer de forges B.(Eds), Tropical Deep-Sea Benthos 23. Mémoires du Muséum national d'Histoire naturelle 191:611-635, ISBN:2-85653-557-7
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]A new scorpionfish, Phenacoscorpius longilineatus n. sp., is described on the basis of 94 specimens from New Caledonia and New Zealand in the southwestern Pacific Ocean, at depths of 345–1089 m. The new species is distinguished from its congeners by the following combination of characters: 8–18 (mode 12) pored lateral-line scales, last of which is situated from below base of seventh spine to below base of fourth dorsal-fin soft ray; no slit behind fourth gill arch; palatine teeth present; second preopercular spine always absent; nuchal and parietal spines distinct; nape and anterior body strongly arched in adults of over ca. 80 mm standard length (SL); post-nuchal-spine length 5.0–9.7% (mean 7.2%) of SL; caudal fin length 21.4–26.7% (mean 23.4%) of SL; 1–5 (mode 2) black spots on posterior half of caudal peduncle; and body usually uniformly whitish without distinct dark saddles in preserved specimens. In addition, P. adenensis Norman, 1939, which is similar to P. longilineatus morphologically, is redescribed on the basis of 3 specimens from the western Indian Ocean and 52 specimens from the southwestern Pacific. The latter represent the first records of this species outside the western Indian Ocean.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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

Abstract [+] [-]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. It is hypothesized that adult sandfish migrate along oceanic ridges to spawn in southern New Caledonian waters.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]A new catshark, Aulohahaelurus kanakorum n.sp., is described from an adult male collected from off south-western New Caledonia. It is the second species in the genus Aulohalaelurus, previously restricted to western Australia. The new species is distinct from its allopatric congener, Aulohalaelurus labiosus (Waite, 1905), mainly by colour pattern, longer interdorsal space, pelvic-anal distance, shorter prepelvic length, morphology of dermal denticles and higher number of diplospondylous vertebrae. A neotype is also designated for A. labiosus (Waite, 1905).

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

(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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Trachinocephalus gauguini Polanco, Acero & Betancur, 2016 was described based on eighteen specimens collected from off the Marquesas Islands, the only location where this species has been recorded until now. Through morphological and molecular examination of Trachinocephalus specimens collected from an exploratory cruise conducted in June 2014 under the Tropical Deep-Sea Benthos program along the northern coast of the New Ireland Province, Papua New Guinea, we demonstrate the presence of this species in Papua New Guinea waters. This new record suggests a wide distribution for this rarely collected species in the western Pacific Ocean.

The new species, Galeus corriganae, is closest to G. priapus from New Caledonia and G. gracilis from northwestern Australia but differs in several morphological characters. A reclassification of the catshark groups is required to revise the familial and generic arrangement of the group.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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?

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]60 Ophiurid species, mainly bathyal, were sampled by MUSORSTOM Expedition in the area of Manila (Philippine Islands) 4 species are new for Science: Astrotoma drachi, Ophioplinthaca manillae, Ophiurothamnus musorstomae, Ophiotreta speciosa. 13 species are refound for the first time since their original diagnosis. A new combination is established, Ophiodaphne formata, because Ophiodaphne materna Koehler (1930) appears to be the juvenile form of “Amphioplus” formatus (Koehler, 1905). Two other species are synonymized: Ophiomoeris pentagona Murakami (1944) with Ophiogyptis nodosa Koehler (1905) and Ophiothrix cumulata Koehler (1922) with Ophiothrix crassispina Koehler (1905). Amphiacantha transacta Koehler (1930) is transferred into fhe genus Amphilimna Verrill.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Recent expeditions to Rapa Nui (also known as Easter Island) and New Caledonia have revealed undescribed species from mesophotic and deeper depths. This includes three new species from Rapa Nui, Hacelia raaraa, Linckia profunda (Ophidiasteridae), Uokeaster ahi (Asterodiscididae) and two new species from New Caledonia, Astroglypha pyramidata n. gen. and Ophidiaster colossus (Ophidiasteridae). 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.

Abstract [+] [-]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.

Abstract [+] [-]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)))).

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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].

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]A new species of Ophiozonella (Ophiuridae, Ophiolepidinae) collected from the bathyal zone of New Caledonia is described and its post-metamorphic growth stages are illustrated and discussed. This species displays different characters inferred to be progenetic, including small size and juvenile morphology. A morphocline of dorsal disc structure in the genus Ophiozonella is elaborated and the general phenomenon of paedomorphosis in the Ophiuridae is considered.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.
