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

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

Résumé [+] [-]Sampling cruises of bathyal benthos in New Caledonia for the years 1993-94 (BATHUS 1-4, SMIB 8, HALIPRO 1). In 1992 and 1993, several oceanographic cruises (BATHUS 1-4) were carried out with the aim of improving the inventory of the benthic fauna of the outer slopes around New Caledonia. On the basis of these results, another cruise (HALIPRO 1) was devoted to the sampling of fishes on slopes suitable for trawling, down to depths of 1100 m. In addition, the SMIB (Substances Marines d'Intérêt Biologique) research program was continued, with a new cruise - SMIB 8 - collecting deepwater invertebrates for experimentation. All of these cruises took place on board the R.V. "Alis" of the Nouméa Research Station (ORSTOM). The present paper gives an account of the fauna collected, the geomorphological characteristics of the zones explored, and an indication of particular studies on the material collected. The latter include population genetics (particularly of Brachiopoda and decapod Crustacea) and crustacean phylogeny. An appendix is provided, giving a list of stations sampled by the various cruises and their general characteristics.

Résumé [+] [-]Verrucomorpha from deep sea collections made by several French cruises to New Caledonia, Loyalty Ridge, Vanuatu, Wallis Island and Futuna Islands, Comoro Islands, and by the French-Indonesian cruise KARUBAR in Indonesian waters, over the period 1985-1994, are investigated. Fourteen species of verrucid are described, including four new species. Verruca jago, Altiverruca jonesae, Brochiverruca crosnieri and Metaverruca maclaughlinae', the bathymetric and geographic ranges of verrucid taxa are extended, and it is confirmed that this is one of the most diverse verrucomorph faunas known. The stams of both Verruca and Metaverruca is considered, and a revised key to genera of the Verrucidae is given.

Résumé [+] [-]An examination of extensive collections made in New Caledonia and nearby islands by the ORSTOM Center in Nouméa, New Caledonia, of collections kept at various museums, and collections of live material made by the author in New Caledonia and in Queensland, Australia, has revealed that a total of 20 species belonging to five genera of trapeziid crabs inhabit the Coral Sea region. Two of the species belonging to the genus Trapezia are described as new. The taxonomic status of several species, particularly Trapezia cymhce (Herbst, 1801), is also revised.

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

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

Résumé [+] [-]The exploratory fishing survey ZoNéCo 6 was canied out on board the R.Y. Alis of the IRD (Institut de Recherche pour le Développement) from 1-14 Décember 1998. lts main objective was to show whether commercial fish resources are present at depths between 300 and 800 m on the outer reef slopes of the Fairway-Lansdowne Bank and the Chesterfield Atoll. Two fishing techniques were used, bottom trawling and bottom longlining. The choice of fishing spots was based on both acoustic surveys using a 28 kHz FURUNO FCY 292 and the bathymetric charts produced during the seabed mapping survey ZoNéCo 4 canied out by the R.Y. L'Atalante. The duration of the trip was splitted into 41, l % devoted to transit, 27 % to bathymetry, 22.3 % to fishing and 9,6 % to waste of time due to bad weather conditions. 17 fishing stations were completed of which 9 were trawl hauls and 8 bottom longline sets amounting to a fishing effort close to 5000 hooks. Three trawl stations and 3 longline sets were made on the slopes of the Chesterfield Atoll whilst 6 trawl stations and 5 longline sets were completed on the slopes of the Fairway-Lansdowne Bank. The total catch was 822 kg of which 243 kg were caught with the trawl and 579 kg with the longline. The trawl did not catch any commercial species, shark amounting to 42 % of the catch, bone fishes 40 %, Crustaceans 9 % and Cephalopods 9 %. The average trawl catch rate was 0,6 tonne/km2 (6,06 kg/ha). The only commercial species caught with the longline were « red snappers» Etelis . carbunculus and E coruscans amounting to 211 kg (36,4 % of the total weight) with a catch rate of 4,3 kg/100 hooks. Sharks dominated the catch both in terms of number and weight (320 kg amounting to 55,3 % of the catch). Gnly one Beryx splendens was caught. With the exception of « red snappers », the survey did not show the presence of commercial target resources within the 300-800 m depth range of the prospected area.

doi: 10.2307/1549308 Résumé [+] [-]Abundant material of the rare lobster genus Thaumastocheles, recently collected from Taiwan, led to an extensive survey of the Indo-Pacific specimens of this genus deposited at various institutions. Altogether 82 specimes of Thaumastocheles from the Indo-Pacific (Madagascar to Japan and New Caledonia at depths of 70-1,753 m) were examined and 2 distinct species are recognized. The 2 species, T. japonicus Calman, 1913, and T dochmiodon, new species, differ mainly in the shape of the cutting teeth of the first chelae and the lateral carinae of the abdominal tergites. Both species are found in Japan, Taiwan, and the South China Sea.

Résumé [+] [-]A new species, Heterocarpus intermedius, confused until now with H. woodmasoni Alcock, 1901, is described after specimens caught off the east coast of Australia, New Caledonia, the Loyalty and the Chesterfield islands, and the Combe and Tuscarora banks. It can be separated mainly by the fact that it has no postrostral crest and only two pairs of dorsolateral spines on the telson. An addition to the indentification key of the Heterocarpus species publishede by Crosnier (1988) is proposed.
Grandperrin, René, Richer de Forges, Bertrand, 1999, Programme «Monts sous-marins» (1990-2000) Bilan final, 49
Résumé [+] [-]Le programme «Monts sous-marins» s'est déroulé au centre IRD de Nouméa depuis 1990 sous la direction de René GRANDPERRIN. Ses objectifs étaient l'étude faunistique des pentes récifales externes, des monts sous-marins et du domaine bathyal supérieur (200-1500 m) et l'évaluation de leurs potentialités halieutiques. 32 campagnes représentant un total de 446 jours de mer ont été effectuées. 18 d'entre elles ont été consacrées à l'halieutique, 13 aux études faunistiques et une à des essais de sondeur. 1496 opérations de prélèvement ont été réalisées (445 pour l'halieutique et 1051 pour la faunistique) avec les engins suivants: casier, chalut à crevettes, chalut de fond à poissons, grand chalut de fond à poissons néo-zélandais, chalut à perche, chalut pélagique à poissons, drague épibenthique, drague à roche, drague Waren et palangre de fond. En ce qui concerne l'halieutique, les ressources des pentes externes (100-600 m) ont été étudiées en Nouvelle-Calédonie et à Vanuatu, archipel pour lequel un atlas des pêches est sous presse. Les monts sous-marins agissent comme des dispositifs de concentration de poissons pour les espèces démersales. En Nouvelle-Calédonie, ils abritent une ressource en Beryx splendens qui fit l'objet d'une exploitation commerciale. Une étude scientifique, basée sur Il campagnes, a pennis de déterminer les paramètres biologiques et dynamiques de l'espèce et de modéliser sa distribution en fonction de la profondeur. Pour la première fois, une corrélation liant la croissance d'un poisson de profondeur avec le phénomène ENSO a été établie. Des travaux de génétiques des populations sont en cours sur cette espèce. Par ailleurs, le programme «Monts sous-marins» collabora étroitement avec le programme ZoNéCo d'identification et d'évaluation des ressources marines de la zone économique de Nouvelle-Calédonie. Deux synthèses portant sur les données thonières et sur les poissons profonds furent réalisées. Un halieute participa aux campagnes de bathymétrie mettant en œuvre un sondeur multifaisceaux à bord du N.O. L'Atalante. Cinq campagnes d'exploration des ressources halieutiques profondes furent effectuées à bord du N.O. Alis à l'aide de chaluts et de palangres de fond. Elles mirent en évidence l'existence de certaines ressources jusque là ignorées des pêcheurs. Les collectes de la faune bathyale ont été réalisées dans le cadre d'opérations conjointes IRD et Muséum national d'Histoire naturelle (MNHN). L'analyse des prélèvements a été possible grâce à un réseau de taxonomistes mis en place par l'IRD (Centre de Nouméa et Antenne du MNHN) et le MNHN ; il compte 181 chercheurs appartenant à 92 institutions de 24 nations différentes, ce qui représente un effort de recherche internationale exceptionnel! Les résultats obtenus dans le Pacifique sud-ouest, et notamment en Nouvelle-Calédonie, ont révolutionné la connaissance de la biodiversité des faunes profondes. 20 volumes des Résultats des campagnes MUSORSTOM qui paraissent dans la série des Mémoires du Muséum national d'Histoire naturelle sont déjà parus (environ 10 000 pages) et un autre est sous presse. Ils traitent de plus de 4500 espèces dont plus de 1300 étaient nouvelles pour la science. 126 genres nouveaux ont été créés de même que 7 familles nouvelles. Au sein de cette étude, la Nouvelle-Calédonie apparaît comme particulièrement riche en espèces et d'une très grande originalité puisque sur-les 1619 espèces actuellement publiées, 60,7 % étaient nouvelles pour la science. Des études phylogénétiques ont été réalisées sur certains groupes zoologiques en utilisant soit des techniques de biologie moléculaire (ADN), soit des méthodes de microscopie électronique. Il s'agit des Crustacés, des Echinodermes (Crinoïdes) et des Brachiopodes, parmi lesquels plusieurs formes panchroniques ont été découvertes. L'accessibilité aux faunes de profondeurs au cours du programme «Monts sous-marins» a permis de récolter des organismes qui ont fait l'objet d'analyses par le programme de pharmacologie (Substances Marines d'Intérêt Biologique: SMIB). Deux bases de données sont directement issues des travaux du programme «Monts sous-marins». Elles concernent les données halieutiques et les données faunistiques. Les premières ont été stockées à la Structure de Gestion et de Valorisation Locale (SGVL) du programme ZoNéCo. Les secondes le sont à l'IRD. Pour chacune d'elles, une procédure de création de sites INTERNET est en cours. Le problème majeur rencontré par le programme fut la disponibilité en personnel. En effet, avec une moyenne de 6 personnes, dont un chercheur et un ingénieur d'étude à plein temps, les effectifs ne dépassèrent jamais un total de 9! Le programme disposa en moyenne de 318 kFlan, dont 40 % sur fonds IRD et 60 % sur financements extérieurs. Les financements extérieurs furent de trois types: FIDES section locale du Territoire de Nouvelle-Calédonie, programme ZoNéCo et, dans une moindre mesure, MAE. Le nombre de publications réalisées par les ressortissants du programme a été de 214, dont 139 pour lesquelles le premier auteur est un membre du programme.
Lemaitre, Rafael, Crosnier, Alain, 1999, Crustacea Decapoda: A review of the species of the genus Parapagurus Smith, 1879 (Parapaguridae) from the Pacific and Indian Oceans, Mémoires du Muséum national d'Histoire naturelle, 20, 180, 303-378
Résumé [+] [-]A review of the deep-water hermit crab species of the genus Parapagurus Smith, 1879 from the Indian and Pacific Oceans is presented based on abundant samples obtained during French expeditions to the New Caledonia region, and supplemented with extensive material deposited in various major museums and institutions throughout the world. A total of 14 species were found to occur in the Indian and Pacific Oceans. Of these seven are new, P. richeri sp. nov., P. furici sp. nov., P. stenorhinus sp. nov., P. saintlaurentae sp. nov., P. janetae sp. nov., P. foraminosus sp. nov., and P. woljfi sp. nov.; and three, P. abyssorum (Filhol, 1885), P. bouvieri Stebbing, 1910, and P. andreui Macpherson, 1984, include parts of the Atlantic Ocean in their distribution. The new species are fully described and illustrated; all previously known species are diagnosed or in the case of one obscurely defined species, P. holihuisi Lemaitre, 1989, redescribed. Information on morphological variations is included for the most abundant species, and a key to aid in the identification of all 14 species is given. Of the seven new species, P. richeri sp. nov. and P. furici sp. nov., were found in the New Caledonia region but are also distributed elsewhere in the Indo-Pacific; P. saintlaurentae sp. nov. and P. stenorhinus sp. nov., have been found exclusively in the Indian Ocean; and P. janetae sp. nov., P. foraminosus sp. nov., and P. wolffi sp. nov., exclusively in the eastern Pacific. As result of this study, the genus now contains 17 species, of which P. pilosimanus Smith, 1879, P. nudus (A. Milne-Edwards, 1891), and P. alaminos Lemaitre, 1986, are so far known only from the Atlantic Ocean. The bathymétrie distribution of all species in the genus is summarized.

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

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

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

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

Résumé [+] [-]Material from recent expeditions off Vanuatu and Wallis and Futuna islands (NE of Fiji) include new records of deep water Pectinoidea. The 20 species recorded from Vanuatu are shared with New Caledonia (80%), Indonesia (70%) and Wallis and Futuna (60%), and the 24 species recorded from Wallis and Futuna are shared with New Caledonia (75%), Indonesia (63%) and Vanuatu (54%). Parvamussium musorstomi sp. novo is described from Wallis and Futuna. The New Caledonia records of Propeamussium maorium are revised and reidentified as P. investigatoris. Parvamussium cristatellum and Propeamussium siratama are recorded and P. richeri sp. novo is described from New Caledonia. A lectotype is designated for Propeamussiwn jefjreysii.

Résumé [+] [-]Maculotriton ingens Houart, 1987 is transfen'ed from Ergalataxinae to Ingensia gen. novo in Muricinae. Phyllocoma Tapparone Canefri, 1881 is tentatively assigned to Muricinae, and Pagodula Monterosato, 1884, a hitherto Mediterranean and eastern Atlantic monotypic genus, is here used to include several Indo-West Pacific, eastern, and western Atlantic species formerly assigned to Trophonopsis Bucquoy & Dautzenberg, 1882 or to Trophon S. l. Additional records of previously described and I or recorded species of Pterynotus Swainson, 1833, Actinotrophon Dall, 1902, Leptotrophon Houart, 1995, and Pagodula Monterosato, 1884 from the New Caledonia region are noted. Eleven new species are described. Five are representatives of Muricinae: Pterynotus (Pterynotus) rubidus sp. nov., Dermomurex (Trialatella) triclotae sp. nov., and Ingensia brithys gen. novo and sp. nov., from New Caledonia, Phyllocoma platyca sp. novo from off Wallis Island, and Poirieria (Actinotrophon) tenuis sp. novo from Vanuatu and off Wallis; one is a muricopsine: Muricopsis (Murexsul) micra sp. novo from New Caledonia; four are trophonine: Leptotrophon alis sp. nov., L. chlidanos sp. nov., L. perclarus sp. nov., and Pagodula procera sp. nov., from New Caledonia; one is a rapanine: Thais (Mancinella) grossa sp. nov., from New Caledonia and Vanuatu.

Résumé [+] [-]The range of shell characters (overall shape, sculpture, columellar plaits, protoconchs) exhibited by fossil and Recent species placed in Exilia Conrad, 1860, Mitraefusus Bellardi, 1873, Mesorhytis Meek, 1876, Surculina Dall, 1908, Phenacoptygma Dall, 1918, Palaeorhaphis Stewart, 1927, Zexilia Finlay, 1926, Graphidula Stephenson, 1941, Benthovoluta Kuroda et Habe, 1950, and Chathamidia Dell, 1956 and the anatomy of the Recent species precludes separation of more than one genus. Consequently all of these nominal genera are synonymised with Exilia, with a stratigraphical range from Late Cretaceous to Recent. Anatomically, Exilia is similar to other ptychatractine genera, but is characterized by a stomach with a long, narrow caecum, a penis with terminal fold surrounding the seminal papilla, and a radula with rachidian teeth with broad lateral flaps. Recent species of Exilia are restricted to deep water at middle to low latitudes in the Indian and Pacific oceans. Exilia hilgendorfi (Martens, 1897) is treated as a species highly variable within its broad IndoPacific distribution, with Benthovoluta gracilior Rehder, 1967, B. claydoni Harasewych, 1987, and B. prellei Bozzetti, 200 I considered local variants. Three new species are described: Exilia graphiduloides sp. nov. (New Caledonia, 520 m), E. vagrans sp. nov. (West and SW Pacific, 865-1280 m), and E. kiwi sp. nov. (New Zealand, 1386-1676 m).
Macpherson, Enrique, Machordom, Annie, 2001, Phylogenetic relationships of species of Raymunida (Decapoda: Galatheidae) based on morphology and mitochondrial cytochrome oxidase sequences, with the recognition of four new species, Journal of Crustacean Biology, 21, 3, 696-714
doi: 10.1651/0278-0372(2001)021[0696:PROSOR]2.0.CO;2 Résumé [+] [-]The species of the genus Raymunida from the Pacific and Indian oceans are revised using morphological characters and the mitochondrial cytochrome oxidase subunit I sequences. Four new species are described (R. confundens. R. dextralis, R. erythrina, and R. insulata), and the status of R. bellior and R. elegantissima are revised. The species of Raymunida can be identified by subtle morphological characters, which match differences in mitochondrial nucleotide sequences. Therefore. the sequence divergences confirm the specific and phylogenetic value of some morphological characters (e.g., length of the mesial spine on the basal antennal segment, length of the walking legs). Furthermore. they confirm the importance of the color pattern as a diagnostic character. The widespread species (R. elegantissima), known from the Philippines to Fiji, shows minimal divergence between specimens from different localities (maximum of 3 nucleotide differences or 0.2% mean divergence). The phylogenetic reconstruction agreed with the monophyletic condition of Raymunida and its differentiation with respect to the genus Munida (in which Raymunida species had previously been included) and Agononida.

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

Résumé [+] [-]The study of a large collection of cryptobranch dorid nudibranchs from deep waters in New Caledonia and the Philippines revealed the presence of Austrodods kerguelenensis (Bergh, 1884); 18 new species belonging to the genera Cadlina, Austrodoris, Geitodods, Discodoris, Peltodoris, Paradoris, Diaulula, Rostanga, Sclerodoris, Baptodoris and Dendrodoris, and two previously undescribed genera, Goslineria and Pharodoris, The anatomy of all these species, including the digestive, reproductive, and nervous system, are studied in detail. All these species are clearly distinguishable from other members of their genera. Most of the species have a pale, simple background coloration, and two of them lack eyes. Both characteristics seem to be adaptations to living in deep waters. Other deep-water Atlantic and Pacific species of dorid nudibranchs have similar adaptations. The two new genera are characterized by the presence of large copulatory spines, numerous flexible spines in Goslineria, and two solid, bifid spines in Pharodoris. No other cryptobranch dorid genera previously described have similar copulatory spines. Some of the species here described belong to genera previously reported from cold or temperate waters, such as Austrodoris, Cadlina and Diaulula. Most of the species belong to genera that are widespread in either cold, temperate or tropical waters (Rostanga, Paradoris, Geitodods and Baptodoris), and only two belong to exclusively tropical genera (Sclerodoris and Dendrodoris). Vicariant events and vertical dispersal could explain the processes of speciation and the origin of these deep-water species.
Valdés, Ángel, Bouchet, Philippe, Marshall, Bruce A., 2001, Deep-water phyllidiid nudibranchs (Gastropoda: Phyllidiidae) from the tropical south-west Pacific Ocean, Mémoires du Muséum national d'Histoire naturelle, 22, 185, 331-368
Résumé [+] [-]Material collected by deep-sea expeditions in the south-west Pacific Ocean reveals a previously unrecognized radiation of the family Phyllidiidae into deeper waters, with a couple of species having a bathymetric range confined below 500 m. Whereas the shallow-water « 100 m) radiation consists mainly of species of Phyllidia, species of Phyllidiopsis make over 70% of the fauna in the 100-500 m interval, and the only two taxa recorded in the 500-750 m interval are species of Phyllidiopsis. A parallel pattern is observed in the Atlantic. There are no consistent anatomical differences between congeneric shallow and deep-water species, but taxa from deeper water are paler and have a simpler dorsal morphology. Twelve new species are described: Phyllidia orstomi sp. novo (Norfolk Ridge, 270-300 m), Phyllidiopsis brunckhorsti sp. novo (New Caledonia, 290350 m), P. anomalasp. Novo (Norfolk and Loyalty Ridges, 240-310 m), P. holothuriana sp. novo (Norfolk Ridge and Vanuatu, 110-240 m), P. macrotuberculata sp. novo (Norfolk Ridge, 270-300 m), P. futunai sp. novo (off Futuna 1., NE of Fiji, 165 245 m),P. crucifera sp. novo (off Futuna 1.,105-160 m), P. lozoueti sp. Novo (Norfolk Ridge, 235 m), P. richeri sp. novo (Norfolk Ridge, 510-750 m), P. circularis sp. novo (Norfolk Ridge, 510-530 m), P. vanuatuensis sp. novo (off Tanna 1., Vanuatu, 410 m), and P. neocaledonica sp. novo (New Caledonia, 315 m). Phyllidia varicosa var.quadrilineata Bergh, 1905, unrecorded since its description from the Flores Sea, Indonesia, is recognized as a valid species of Phyllidiopsis and recorded from Vanuatu in 160 -180 m.
Bouchet, Philippe, Petit, Richard E., 2002, New species of deep-water Cancellariidae (Gastropoda) from the southwestern Pacific, The Nautilus, 116, 3, 95-104
Résumé [+] [-]One new genus and nine new species of Cancellariidae are described from New Caledonia from depths between 200 and 600 meters. They are: Africotriton adelphum new species, Mirandaphera new genus, Mirandaphera cayrei new species, Mirandaphera maestratii new species, Merica marisca new species, Sveltia rocroii new species, Sveltia splendidula new species, Nipponaphera pardalis new species, Nipponaphera cyphoma new species, and Nipponaphera goniata new species. Africotriton adelphum new species is the first species in that genus known from outside South Africa and Australia. The new genus Mirandaphera is characterized by its broad, non-umbilicate shell with very large crenulated axial ribs, and axial columella. The genus is composed of the new species described herein, Mirandaphera maestratii new species and M. cayrei new species, and two other species: M. tosaensis (Habe, 1961) new combination and M. arafurensis (Verhecken, 1997) new combination, from deep water off Japan and the Arafura Sea respectively. Trigonaphera teramachii Habe, 1961 and Agatrix. nodosivaricosa Petuch, 1979 are transferred to Nipponaphera. New species of Merica, Sveltia, and Nipponaphera are the deepest dwelling known representatives in their respective genera.
Crosnier, Alain, 2002, Révision du genre Parathranites Miers, 1886 (Crustacea, Brachyura, Portunidae), Zoosystema, 24, 4, 799-825
Résumé [+] [-]Based on rather abundant material from the Indo-West Pacific, the number of species in the genus Parathranites Miers, 1886 is elevated from two to eight. The six new species are P. granosus n. sp., P. tuberosus n. sp., P. tuberogranosus n. sp., P. ponens n. sp., P. intermedius n. sp. and P. parahexagonum n. sp. Examination of the type series of the type species for the genus, P. orientalis Miers, 1886, shows that it contains two species; a lectotype is designated for P. orientalis. The main morphological characters used for differentiating the species are the breadth/length ratio of the carapace (correlated with the length of the fifth anterolateral teeth of the carapace) which can vary from 1.3 to 2.1, the presence or absence of a median tubercle on the posterior part of the cardiac area, the granulation of the carapace and the shape of the first male pleopods. An identification key for members of this genus is proposed.

Résumé [+] [-]A revision is provided of the Indo-Pacific species of the subfamily Scyllarinae. All of these species were formerly placed in the genus Scyllarus Fabricius, 1775, but a closer study revealed that several genera could be distinguished within the subfamily. The 13 new genera now recognized in the Indo-Pacific biogeographic region are as follows: Acantharctus n. gen., Antarctus n. gen., Antipodarctus n. gen., Bathyarctus n. gen., Biarctus n. gen., Chelarctus n. gen., Crenarctus n. gen., Eduarctus n. gen., Galearctus n. gen., Gibbularctus n. gen., Petrarctus n. gen., Remiarctus n. gen. and Scammarctus n. gen. Diagnoses and keys are provided for all the genera and their species. New and insufficiently known species have been described extensively, for the others additional morphological details are given. New species are: Bathyarctus chani n. gen., n. sp., B. steatopygus n. gen., n. sp., Petrarctus veliger n. gen., n. sp., Chelarctus crosnieri n. gen., n. sp., Eduarctus pyrrhonotus n. gen., n. sp., E. marginatus n. gen., n. sp., E. perspicillatus n. gen., n. sp. and E. reticulatus n. gen., n. sp. Furthermore efforts were made to provide each species with a complete synonymy, a description of the colour, its biology, habitat and geographical distribution. All the material examined is listed in detail. Where appropriate, remarks are provided on nomenclature, published data on the larval development and other topics.

Résumé [+] [-]Six new species of squaloid sharks of the genus Etmopterus are described from the Arafura and Banda Seas (south-east Indian Ocean), and the Coral Sea (south-west Pacific): E. fusus sp. nov. from the slope of northwestern Australia; E. evansi sp. nov. from northwestern Australia and eastern Indonesia; E. dianthus sp. nov. from the Coral Sea; E. dislineatus sp. nov. off tropical eastern Australia; and E. caudistigmus sp. nov. and E. pseudosqualiolus sp. nov. from the slopes of the Chesterfield Islands, New Caledonia, and the northern part of the Norfolk Ridge. They can be distinguished by their coloration, body shape, teeth morphology, vertebral counts, dermal denticles, the position of their fins, and the size and shape of luminescent markings on the flank, caudal peduncle and caudal fin. A key for the Etmopterus species of tropical Australasia is provided.

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

Three species (Astrogynmotes hamishia Baker et al. , 2001, Astrothamnus sp., Ophioli/J/na antarctica (Lyman, 1879)) representing the main groups Ophiomyxidae, Euryalida, and Ophiacanthidae are presented briefly, illustrated with scanning electron micrographs, as examples of the Im·ger work that will be published elsewhere after the project will be finished.
Galil, Bella S., 2003, Four new genera of leucosiid crabs (Crustacea: Brachyura: Leucosiidae) for three new species and nine species previously in the genus Randallia Stimpson, 1857, with a redescription of the type species, R. ornata (Randall, 1939)., Proceedings of the Biological Society of Washington, 116, 2, 395-422
Résumé [+] [-]A study of the leucosiid genus Randallia Stimpson, 1857, led to the description of four new genera: Tanaoa, for R. distincta Rathbun, 1893, R. pustulosa Wood-Mason, in Wood-Mason & Alcock, 1891, and a new species, T. nanus; Tokoyo for R. eburnea Alcock, 1896, and a new species, T. cirrata; Toru for R. granuloides Sakai, 1961, R. trituberculata Sakai, 1961, R. pila Tan, 1996, R. mesjatzevi Zarenkov, 1990, and a new species, T. septimus\ and Urashima, for R. lamellidentata Wood-Mason, 1892, and R. pustuloides Sakai, 1961. Randallia is restricted to its type species, R. ornata (Randall, 1839), and provisionally 12 other species currently placed in this genus pending further revision. All new genera are diagnosed and species assigned to them described or redescribed and illustrated; extended synonymies are given, and a key for species identification is provided. The type species, R. ornata, is redescribed.

Résumé [+] [-]Four new species of urolophid stingarees are described from the Coral Sea (South-West Pacific): Urolophus deforgesi sp. nov. and U. papilio sp. nov. from the continental slope of the Chesterfield Islands; U. neocaledoniensis sp. nov. is more widely distributed on the slopes of the Chesterfield Islands and New Caledonia and along the northern part of the Norfolk Ridge; U. piperatus sp. nov. is restricted to the coast of northern Queensland (Australia). The holotype and only known specimen of a rare and unusual stingaree, U. annatus Val. in Muller & Henle, 1841 from New Ireland (Bismark Archipelago), is redescribed and it could represent a new genus. The new species are mainly distinguished by a combination of the following characters: disc shape (particularly its width), dorsal fin (present or absent), interorbital distance (narrow or broad), tail length (short or elongated), coloration (plain or with spots), and oral papillae, vertebrae and pectoral-fin radial counts. A key for the urolophids of the Coral Sea is provided.
Baba, Keiji, 2004, Uroptychodes, new genus of Chirostylidae (Crustacea: decapoda: Anomura) with description of three new species, Scientia Marina, 68, 1, 97-116
Résumé [+] [-]Examination of materials collected from Indonesia, New Caledonia and vicinity, now deposited in the Museum National d'Histoire Naturelle, disclosed three additional undescribed species of chirostylids belonging to the Uroplychus spinimarginatus group. The group is now shifted to a distinct genus Uroptychodes. Uroptychus grandirostris Yokoya, 1933, which can be transferred to Uroptychodes, has been a problematic species because of the brevity of the original description and the loss of the type material. However, a recent finding of a specimen, which is in poor condition, very much like the illustration of U. grandirostris by Yokoya (1933: Fig. 29), but different from the description of U. grandirostris given by van Dam (1939) for one of the type specimens, suggests that the type material of U. grandirostris includes at least two species. In this paper a neotype is selected for U. grandirostris. The genus Uroptychodes now contains 10 species. All these species are reviewed and a key to the species of the genus is provided.
Bouchet, Philippe, Kantor, Yuri I., 2004, New Caledonia: The major centre of biodiversity for volutomitrid molluscs (Mollusca: Neogastropoda: Volutomitridae), Systematics and Biodiversity, 1, 4, 467-502
doi: 10.1017/S1477200003001282 Résumé [+] [-]Recent deep-sea explorations in the South Pacific have documented around New Caledonia the most diverse fauna of gastropods of the family Volutomitridae anywhere in the world. Fourteen species (nine new, two remaining unnamed) are recorded, all essentially confined to the 250–750 m depth range. The high number of species in the New Caledonia region does not appear to be an effect of sampling intensity, but appears to result from four factors: regional spatial heterogeneity, frequency of hard substrates, syntopy, and a historical heritage shared with Australia and New Zealand, which until now ranked as the major centre of volutomitrid diversity. In the New Caledonia region, volutomitrids show a marked preference for hard bottoms and up to three species may cooccur in the same dredge haul. Many species appear to have extremely narrow geographical distributions within the region (e.g. a single seamount or a single submerged plateau); conversely, Microvoluta joloensis, the only non-endemic volutomitrid present in New Caledonia, ranges from the Mozambique Channel to Tonga.

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

Résumé [+] [-]The Pasiphaea cristata species group is treated herewith, as the second part of the revision of genus Pasiphaea Savigny, 1816. The group is primarily characterized by presence of a complete gill formula, unarmed posterior margin of the merus of the first pereopod, and unarmed posterior margin of the ischium and basis of the second pereopod. The group comprises twenty two species, four of which are new species from MUSORSTOM material. Pasiphaea nishiei Iwasaki proves to be a junior synonym of P. merriami Schmitt, and P. vereschhaka Burukovsky is probably a junior synonym of P. amplidens Bate. Pasiphaea australis Hanamura has the same pereopodal armatures as this group, but entirely lacks arthrobranchs and is referred to Alainopasiphaea Hayashi. The genus Pasiphaea is redefined by including Phye Wood-Mason as a synonym. A key to the species of P. cristata group is presented. Each species is defined and most species are redescribed and/or refigured.
Komai, Tomoyuki, Marshall, Bruce A., Richer de Forges, Bertrand, 2004, A review of the Indo-West Pacific species of the genus Glyphocrangon A. Milne-Edwards, 1881 (excluding the G. caeca species group) (Crustacea: Decapoda: Caridea: Glyphocrangonidae), Mémoires du Muséum national d'Histoire naturelle, 23, 191, 375-610
Résumé [+] [-]A review of the species of the caridean genus Glyphocrangon A. Milne-Edwards, 1881 from the Indo-West Pacific Oceans is presented based on rich collections formed during French expeditions to various regions, and supplemented by extensive material deposited in various institutions throughout the world. The genus is divided into two informal groups primarily based on the development of the eye and the presence or absence of arthrobranchs on the first and second pereopods. This study treats species characterized by a well-developed eye and the presence of arthrobranchs on the first and second pereopods (herein called the Glyphocrangon spinicauda species group). A total of 54 species are recognized in the G. spinicauda species group from the Indo-West Pacific region. Of these, the following 28 are new to science: G. albatrossae (Philippines), G. amblytes (Madagascar and South Africa), G. armata (New Caledonia, Vanuatu, Fiji, Wallis and Futuna islands), G. boletifera (Gulf of Aden), G. chacei (Philippines), G. confusa (Indonesia), G. cornuta (New Caledonia), G. crosnieri (Madagascar), G. conodactylus (New Caledonia), G. dimorpha (New Caledonia), G. ferox (Madagascar), G. formosana (Taiwan and East China Sea), G. indonesiensis (Philippines and Indonesia), G. kapala (eastern Australia), G. saintlaurentae (western Indian Ocean), G. major (New Caledonia), G. lineata (Indonesia and northwestern Australia), G. parva (Philippines), G. perplexa (Japan and Taiwan), G. proxima (Philippines and Indonesia), G. punctata (Philippines), G. richeri (Wallis and Futuna islands), G. robusta (Philippines), G. rubricinctuta (Wallis and Futuna islands), G. runcinata (East China Sea), G. similior (Coral Sea), G. speciosa (New Caledonia), and G. tasmanica (Tasman Sea). Glyphocrangon andamanensis Wood-Mason & Alcock, 1891 and G. mabahissae Calman, 1939, which have been considered to be synonymous with G. investigatoris Wood-Mason in Wood-Mason & Alcock, 1891 and G. dentata Barnard, 1926 respectively, are found to be distinct species. Glyphocrangon juxtaculeata Chace, 1984, the holotype of which is a juvenile, is considered to be a junior subjective synonym of G. regalis Bate, 1888. Glyphocrangon joani Allen & Butler, 1994 is treated as a junior synonym of G. fimbriata Komai & Takeuchi, 1994. Plastocrangon Alcock, 1901 is interpreted as a synonym of Glyphocrangon. The new species are fully described and illustrated, and all but three of the previously known species are redescribed and illustrated: G. gilesii and G. smithii being diagnosed on the basis of published information, G. unguiculata Wood-Mason in Wood-Mason & Alcock, 1891 on published information and provisionally identified material from the western Pacific. One obscurely diagnosed species, G. wagini Burukovsky, 1990 from the southeastern Pacific, is also redescribed in order to establish its affinities. Lectotypes are designated for G. acuminata Bate, 1888, G. pugnax de Man, 1918, G. assimilis de Man, 1918, G. sibogae de Man, 1918, and G. megalophthalma de Man, 1918. Identification key, separated by sex, is provided. This study reveals that most Glyphocrangon species have restricted geographical ranges, with only G. caecescens occurring in both the western Pacific and Indian oceans. The geographic and bathymetric distributions of the treated species are summarized.

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

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

Résumé [+] [-]The hermit crab genus Nematopagurus, erected by A. Milne-Edwards & Bouvier (1892) for a single Atlantic species, has vastly larger reported representation in the Indo-Pacific region. However, the majority of species have been described on the basis of one or only a few specimens. The Musorstom expeditions to the south central Pacific and Philippine Islands, supplemented by the surveys of the United States Fish Commission steamer Albatross in Hawaiian, Philippine and Japanese waters, have provided not only a substantial amount of new material, but sufficient representation of most described species to permit the evaluation of intraspecific morphological variation. As a result, although five new species have been recognized, three recently described species have proven to be junior synonyms of previously known, but poorly represented, species. Nematopagurus holthuisi McLaughlin & Hogarth and N. pilosus Komai are synonymous with N. gardineri Alcock, while N. shinnyoae Komai is synonymous with N. kosiensis McLaughlin. The range of N. diadema Lewinsohn, reported previously from the Red Sea, the eastern coast of South Africa, and the South China Sea, has been extended to Fiji, while that of N. meiringae McLaughlin, known from eastern South Africa and the South and East China Seas, has been extended to the Philippine Islands. Nematopagurus kosiensis McLaughlin, previously known only from eastern South Africa has been found not only in Japanese waters, but also as far east as the Hawaiian Islands. Species identified by several authors as N. squamichelis Alcock and N. muricatus (Henderson) have been reexamined and correctly reassigned to other taxa. Descriptions and illustrations are presented for all species, together with a key for their recognition.

Résumé [+] [-]In this second study of MUSORSTOM Hexactinellida from New Caledonia, the Loyalty Islands, Wallis and Futuna Islands, and some seamounts from the South Pacific, 31 species (22 new) of Lyssacinosida, and a new subspecies of Caulophacus lotifolium Ijima, are described. New members of the formerly monotypic lyssacinosid genera Saccocalyx, Dictyaulus, Dictyocalyx, Neocaledoniella and Hyalostylus are described, and Neocaledoniella is introduced as a replacement name for the Caledoniella Tabachnick & Lévi in Tabachnick 2002, which is preoccupied.

doi: 10.1080/00222930500060595 Résumé [+] [-]The stalk morphology of the deep-sea stalked crinoid Guillecrinus changes a lot from juvenile to adult. As a result of its unusual morphology among the extant crinoids, its taxonomic and phylogenetic affinities remain unsettled. Distinctive morphological changes characterize the various growth stages in stalked crinoids. We conduct and discuss a detailed ontogenetic analysis of the stalk of the two species (Guillecrinus neocaledonicus and G. reunionensis) of this Indo-Pacific genus, which was observed in its environment during submersible dives off New Caledonia. Analyses examined (1) morphological changes, (2) the degree of change in morphology, (3) architectural constraints, and (4) the functional constraints related to environmental factors. The relations between three levels of integration were examined: the ossicle (columnal), the stalk, and the complete individual. The changes in level of organization were estimated. The analysis reveals that the external stalk morphology of Guillecrinus goes from a pronounced xenomorphic type in juveniles, characterized by diversified columnal articulations, which provide the proximal and distal part of the stalk with a considerable degree of flexibility, to a dominant homeomorphic type in adults, characterized by columnal articulations which allow little or no movement. This ontogenetic change through a mosaic of heterochronic developments corresponds with a change in the hydrodynamic environment, from a turbulent to a laminar water flow, and from nutritional contraints. The extensive development of deep ligament fossae in adults and in the distal stalk of juveniles corresponds to a relatively low allocation of energy to the skeleton, rather than a functional necessity. Proximal columnals in juvenile Guillecrinus display characteristics of adult Hyocrinidae. Distal columnals exhibit the typical morphology observed in Bourgueticrinina. Juveniles stages of both proximal and distal columnals show a high degree of specialization (derived characters). Well-supported classifications have typically placed the Bourgueticrinina and the Hyocrinidae in two very dissimilar groups. Specific characteristics from the three very different families Bathycrinidae, Guillecrinidae and Hyocrinidae appear to be expressed either separately (Hyocrinus or Bathycrinus) or together (Guillecrinus). Their expression appears to depend on functional and environmental constraints. The transformation of columnals from juvenile to adult shows the important role of hypermorphic processes. However, no evidence of phylogenetic recapitulation was observed. Does the evidence presented here support or disprove current taxonomic interrelationships? How does morphology relate to ontogeny? Is heterochrony involved?
Crosnier, Alain, 2005, Deux Parapenaeus nouveaux (Crustacea, Decapoda, Penaeidae) du Sud-Ouest Pacifique, Zoosystema, 27, 2, 267-266
Résumé [+] [-]During the French cruises conducted in the South-West Pacific during the last 20 years, two new Parapenaeus were found: Parapenaeus kensleyi n. sp., off New Caledonia, Vanuatu and the Fiji Islands; and Parapenaeus cayrei n. sp., off Tonga and the Chesterfield Islands. Amongst the Parapenaeus species provided with a branchiostegal spine on the anterior border of the carapace and extended by a rather long carina, P. kensleyi n. sp., with its long and sinuous rostrum, is related to P. australis Dall, 1957, P. lanceolatus (Bate, 1881) and P. perezfarfante Crosnier, 1986. Parapenaeus cayrei n. sp., with its short and straight rostrum, is related to P. fissurus (Bate, 1881), P. sextuberculatus Kubo, 1949 and P. ruberoculatus Hall, 1962. In both cases, the shape of the distal part of the ventrolateral lobe of the petasma in the males, the arrangement of the lateral bulbous portions and median tubercles, and the bulgings of the thelycum in the females allow the new species to be readily distinguished.
Dayrat, Benoit, Gosliner, Terrence M., 2005, Species names and metaphyly: a case study in Discodorididae (Mollusca, Gastropoda, Euthyneura, Nudibranchia, Doridina), Zoologica Scripta, 34, 2, 199-224
doi: 10.1111/j.1463-6409.2005.00178.x Résumé [+] [-]Absence of resolution in phylogenetic trees, or metaphyly, is a common phenomenon. It mainly results from the fact that each data set has its own limit and can hardly be expected to reconstruct alone an entire hierarchy. Because metaphyly helps point out which regions of a tree merit further investigation, one should not avoid metaphyly but rather should try to detect it by addressing carefully node reliability. In this paper we explore the implication of Inetaphyly for species names. We present a phylogenetic analysis of Discodorididae (Mollusca, Gastropoda, Nudibranchia, Doridina), with an emphasis on relationships among species of Discodoris and its traditionally close 'allies' such as Peltodoris and Anisodoris. We demonstrate that some species must be transferred to different discodoridid subclades with which they share synapomorphies, but that many species form a metaphyletic group At the base of Discodorididae, and therefore cannot be placed in any taxon of genus level. We demonstrate that the current International Code of Zoological Nomenclature does not allow taxonomists to handle this situation because it requires selecting a taxon name of genus rank for every species binomial. Then we evaluate the results provided by new forms of species names, both in a rank-based system, such as the current nomenclature, and a rank-free system. All solutions considered would cause radical changes to the 'spirit' of the current ICZN (and, by extension, to the other current codes). In a rank-free system of nomenclature, such as the PhyloCode, the best result is obtained with an epithet-based form that does not mention supra-specific relationships. Under this method, official species names would take the form 'boboliensis Bergh, 1877', although page numbers and letters can be added for uniqueness purposes. Taxonomists would then be free to add supra-specific taxon names in 'common' species names, such as Discodorididae boholiensis Bergh, 1877 or simply Discodorididae boboliensis. Here we wish to stimulate discussion of a problem that we believe merits wide debate: absence of resolution in phylogenetic reconstruction and its impact on species nomenclature.

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

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

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

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

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

The new species are all Pontoniinae: Mesopontonia brevicarpalis sp. nov., Palaemonella komaii sp. nov., Periclimenes crosnieri sp. nov., Periclimenes forgesi sp. nov., Periclimenes loyautensis sp. nov., Periclimenes paralcocki sp. nov., Periclimenes paraleator sp. nov., and Periclimenes pseudalcocki sp. nov. The last six new species are members of the deep-water "Periclimenes alcocki species complex'', which has more than two ( usually four) pairs of dorsolateral telson spines anterior to the posterior telson margin, the cornea is usually reduced, the dactyl of the major second chela is generally flanged and the chela is sometimes covered with small tubercles. The complex is usually found at more than 200m depth in the West Pacific. The species can be distinguished from each other by the armature of ambulatory propod and dactyl, diameter of cornea, rostrum shape and the number of pairs of dorsolateral telson spines. Mesopontonia brevicarpalis sp. nov., from the southeast coast of Africa, is the seventh species of the genus. Palaemonella komaii sp. nov. is very similar to Palaemonella dolichodactylus Bruce, 1991 and Palaemonella hachijo Okuno, 1999. These three species share the features of very long and slender ambulatory pereiopods with the dactyl more than eight times longer than its basal depth and with several long setae on the dorsal dactylar margin.

Résumé [+] [-]Two new species of Axioidea were found amongst the deep-sea material recently collected from New Caledonia. Meticonaxius dentatus sp. nov. is unique among members of the genus by the presence of the teeth on the rostrum and the merus of the large cheliped. Oxyrhynchaxius tricarinatus sp. nov. is the third species known in the genus and is unique in bearing three dorsal ridges on the abdome

Résumé [+] [-]A phylogenetic analysis of 13 taxa and 32 characters resulted in a single most parsimonious tree that supports monophyly of the goniasterid (Echinodermata, Asteroidea) genus Circeaster Koehler, 1909 and supports re-establishment of the genus Lydiaster Koehler, 1909. The phylogeny supports monophyly of the ingroup, including 10 species, six of which, C. kristinae n. sp., C. helenae n. sp., C. arandae n. sp., C. loisetteae n. sp., C. sandrae n. sp., and C. pullus n. sp., are new. Phylogenetic results support diversification into the Indian, Pacific, and Atlantic ocean basins. The phylogeny is constrained by a sister taxon with a Cretaceous fossil occurrence and two geologic events, including the closure of the Indonesian seaway and formation of the Panamanian isthmus. These events formed barriers limiting or preventing larval dispersal between the Indian/Pacific and the Pacific/Atlantic oceans. Larval dispersal through a deep-sea environment was a signifi cant consideration for estimating timing constraints from paleoenvironments. Based on fossil constraints, ancestry for the lineage is suggested as early as the Late Cretaceous with subsequent diversification in the Cenozoic. In situ observations of Circeaster perched on bare deep-sea coral skeletons and morphological similarities with other known corallivorous goniasterids suggest important ecological roles in the deep-sea.
McLay, Colin L., Richer de Forges, Bertrand, Justine, Jean-Lou, 2006, Retroplumidae (Crustacea, Decapoda) from the Indo-Malayan archipelago (Indonesia, Philippine) and the Melanesian arc islands (Solomon Islands, Fiji and New Caledonia), and paleogeographical comments, Mémoires du Muséum national d'Histoire naturelle, 24, 193, 375-391
Résumé [+] [-]Seven species of retroplumid crabs are recorded from Indonesia, Philippine Islands, Solomon Islands, Fiji Islands and New Caledonia. These include Retropluma denticulata (Solomon Islands), R. notopus (Fiji), R. plumosa (Fiji), R. quadrata (Philippine Islands), R. serenei (Fiji Islands and New Caledonia), R. laurentae n. sp. (Indonesia, Philippine Islands, Solomon Islands and New Caledonia), and Bathypluma forficula (Solomon Islands and New Caledonia). The new material considerably extends the distribution of retroplumid crabs eastwards in the Pacific and also extends the depth range of several species. There are now ten extant species of retroplumids known in two genera: Bathypluma de Saint Laurent, 1989 and Retropluma Gill, 1894. Although larval development is unknown, their small egg size suggests that retroplumids have indirect development. Three fossil genera, containing eight species, are recognized: Costacopluma Collins & Morris, 1975, Retrocypoda Via Boada, 1957 and Loerenthopluma Beschin et al. 1996. Some of the fossils placed in the Retroplumidae probably belong to the Palicidae Bouvier, 1898. An analysis of recently discovered fossil retroplumids shows that this family first appeared in the Proto-Atlantic Ocean during the Late Cretaceous, but became extinct in the Atlantic by the Pliocene. The family is now only found in Indo-West Pacific seas.
Poutiers, Jean-Maurice, 2006, Two new species of protocardiine cockles (Mollusca, Bivalvia, Cardiidae) from the tropical Southwest Pacific, Zoosystema, 28, 3, 635-654
Résumé [+] [-]The two new species described in this paper are widely distributed in the tropical south-western Pacific; they have been found on the upper continental shelf of the area, around New Caledonia, westward to Chesterfield Islands and Lord Howe Ridge, southward to northern part of Norfolk Ridge, north- and eastward to Vanuatu, Fiji and Tonga islands. They belong to two often confused genera of subfamily Protocardiinae (sensu Keen 1980), Frigidocardium Habe, 1951 and Microcardium Th iele, 1934, that are briefly characterized herein. Frigidocardium valdentatum n. sp. is characterized by the peculiar sculpture of mid-posterior slope ending in strongly dentate margin. Frigidocardium kirana is a similar species with lower outer sculpture, more asymmetrical shape and rather strong umbonoventral fold; it is first recorded here from the tropical Southwest Pacific and Mascarene islands. Diagnostic features of Microcardium trapezoidale n. sp. include rather high trapezoidal shape and posterior sculptural area extending on 2/5 of shell length, with an anterior limit almost parallel to radial ribs in the adult and well-developed, non lamellous sculpture in the rib interstices. A comparative review of all Recent Microcardium species in the Indo-West Pacific is given, to place the new species in the context of the genus. Five Microcardium species are presently known in this area: M. gilchristi from southern Africa, M. simillimum n. comb. (for Cardium (Fragum) simillimum) from Sri Lanka and Mascarene Plateau, M. sakuraii from Japan and the Philippines (new record), M. aequiliratum from the Philippines, and M. tenuilamellosum from the Philippines and Solomon Islands (new record).
Castro P., 2007, A reappraisal of the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) and revision of the subfamily Goneplacinae, with the description of 10 new genera and 18 new species, Zoosystema, 29, 4, 609-774
Résumé [+] [-]A reappraisal of the taxonomy of the brachyuran crabs belonging to the family Goneplacidae MacLeay, 1838 sensu lato has resulted in the revision of the subfamily Goneplacinae, which combines the subfamilies Goneplacinae MacLeay, 1838 and Carcinoplacinae H. Milne Edwards, 1852. Most of the 66 species of Goneplacinae sensu stricto that are listed herein inhabit relatively deep water and are infrequently collected. The subfamily Goneplacinae sensu stricto now consists of 17 genera of which 10 are being described as new: Carcinoplax H. Milne Edwards, 1852, with 18 species of which four are new; Entricoplax n. gen., monotypic; Exopheticus n. gen., with two species; Goneplacoides n. gen., monotypic; Goneplax Leach, 1814, with four species; Hadroplax n. gen., monotypic; Menoplax n. gen., monotypic; Microgoneplax n. gen., with five species of which four are new; Neogoneplax n. gen., with three species of which two are new; Neommatocarcinus Takeda & Miyake, 1969, monotypic; Notonyx A. Milne-Edwards, 1873, with three species; Ommatocarcinus White, 1852, with four species; Paragoneplax n. gen., monotypic; Psopheticus Wood-Mason, 1892, with four species; Pycnoplax n. gen., with five species of which one is new; Singhaplax Serene & Soh, 1976, with seven species of which four are new; and Thyraplax n. gen., with five species of which three are new. All goneplacine genera are exclusive to the Indo-West Pacific region (plus contiguous temperate areas) except Goneplax, which is so far known mostly from the Atlantic and Mediterranean regions. Four nominal species described by other authors were found to be junior subjective synonyms for other species: Carcinoplax verdensis Rathbun, 1914 and C polita Guinot, 1989 synonymous of C specularis Rathbun, 1914; Goneplax megalops Komatsu & Takeda, 2003 of Goneplacoides marivenae (Komatsu & Takeda, 2003) n. comb.; and Psopheticus insolitus Guinot, 1990 of P stridulans Wood-Mason, 1892.

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

Poppe, Guido T., Groh, Klaus, Vos, Chris, Terryn, Yves, 2007, The family Tonnidae, A conchological iconography
Résumé [+] [-]Before talking about a largely underestimated and poorly known, yet so beautiful family of Gastropoda, there is an issue which I must attract your attention to. While gathering the necessary information, shells and literature, I often wondered why people still call some of the Tonnidae by the wrong name, despite the sometimes meticulous research done by scientists in the past. Is it because of the often controversial information in the available publications? Is it for lack of decent information? This issue became clear to me when I was looking into the most recent publications on Eudolium such as Piani (1977), Marshall (1992) and Bouchet & Waren (1993). All concluded that what is usually sold as Eudolium pyriforme is in fact Monterosato 's true Eudolium crosseanum. I must say I was a bit shocked to read those papers and see some photographs of the type material. Why were erroneous names still used ifproofwas there, clearly and undoubtedly, to the contrary? It took me a few weeks and a few discussions with Dr Philippe Bouchet and Dr Alan Beu to figure it out, but in the end, the answer is simple: In scientific terms, proof is given by photography and description, and maybe by discussion, but not in such words or language that they are understandable to the untrained reader. Also, such research is often documented in broader publications (e.g. Bouchet & Waren, 1993; Beu, 2005) that don't attract the attention of the advanced amateur or naturalist straight away, and are wrongfully neglected. These works are seldom offered commercially, and thus unjustly remain unknown to the wider public. It is in this respect that works such as the Concho logical Iconography, often written by advanced naturalists, have their true value and Guido Poppe, Klaus Groh and Yves Terryn must be commended for an initiative such as this is an excellent medium to bring science and amateur collecting closer together in an attempt to cover the gap between the two. It is my ambition to give a synoptical overview ofthe existing (described) species, based on my collection of well over 1000 specimens and an ever-increasing library of historical as well as recent publications. Ten years of collecting and studying shells and publications have resulted in what is to follow. I have listed the most important synonyms for each species in order to clarify some of the dubious issues, but the lists are not exhaustive. Although I have many of the old publications through digital photography, I'm sure that there are still many more out there. And even if I was to spend another month in the libraries of, e.g. the BM(NH) or the MNHN, there will still be publications "hidden" somewhere. I mainly concentrate my research on Recent material, whilst a lot has been described in the fossil area as well. For example: recently, Dr Alan Beu discovered that there is an earlier name for what we all know as Eudolium pyriforme (G. B. Sowerby III, 1914), namely Eudolium javanum (Martin, 1879), originally described as the fossil Cassidariajavana from the late Miocene oflndonesia. While researching this, he also discovered names such as Dolhun hochstetteri Martin, 1879 (= Tonna allium (Dillwyn, 1817)) just to give one example. Another issue is interpretation. Many have interpreted, e.g. Adanson's "Le Minjac" in different ways. For one author, it is T. marginata (Philippi, 1845), for another author T. tessellata (Lamarck, 1816). March (1852) even lists it as a full species, D. minjac. In order to clarify such matters, I have tried to compare specimens with type material. This publication should be a solid basis for any future researcher in this family and I do hope you will all find the necessary answers to your basic tun-related questions to start that collection you always wanted to start.

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

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

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

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

Résumé [+] [-]Galeus priapus sp. Nov. Is described from specimens collected on the slopes of the seamounts and ridges of southern New Caledonia and Vanuatu. It is the first Galeus species recorded in these areas. G. priapus is characterised by the presence of a conspicuous crest of enlarged denticles on the dorsal caudal margin, the absence of similar crest on ventral caudal margin, and extremely long and slender claspers in adult males that extend posteriorly to the anal-fin origin. 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.

Valdés, Ángel, Héros, Virginie, Cowie, Robert H., Bouchet, Philippe, 2008, Deep-sea “cephalaspidean” heterobranchs (Gastropoda) from the tropical southwest Pacific, Mémoires du Muséum national d'Histoire naturelle, 25, 196, 587-792
Résumé [+] [-]One hundred and twenty-one species of deep sea “cephalaspidean” heterobranchs belonging to the genera Acteon, Crenilabium, Obrussena, Rictaxis, Japonacteon, Maxacteon, Bullina, Diaphana, Toledonia, Cylichna, Scaphander, Sabatia, Roxania, Cylichnium, Acteocina, Truncacteocina, Philine, Retusa, Pyrunculus, Volvulella, Relichna, Micratys, Gastropteron, Aglaja and Philinopsis are reported from the tropical southwest Pacifi c. Thirty-nine of these species are new: Acteon ionfasciatus, Acteon chrystomatus, Rictaxis sanguinea, Japonacteon longissimus, “Acteon” editus, “Acteon” buccinus, “Acteon” ringiculoides, “Acteon” boteroi, “Acteon” loyautensis, “Acteon” rhektos, “Acteon” profundus, “Acteon” osexiguus, “Acteon” aphyodes, “Acteon” herosae, “Acteon” comptus, “Acteon” chauliodous, “Acteon” cohibilis, Bullina rubropunctata, Toledonia neocaledonica, Toledonia epongensis, Cylichna tanyumphalos, Cylichna grovesi, Sabatia pyriformis, Roxania smithae, Cylichnium mucronatum, Cylichnium nanum, Acteocina lata, Philine habei, Philine babai, Philine abyssicola, Retusa diaphana, Retusa insolita, Retusa lenis, Retusa abyssicola, Retusa trunca, Volvulella onoae, Volvulella multistriata, Relichna hadra and Micratys wareni. A previously described species, Acteon aequatorialis, is included in the new genus Bathyacteon. Three species are assigned provisionally to already described species until more material becomes available: Acteon cf. nakayamai, Maxacteon cf. kawamurai, “Acteon” laetus. Thirty-eight species remain unnamed because of the absence of adequate information, but the shells are illustrated. Most species are described based on conchological data. Fourteen species of Acteonidae and two of Retusidae are provisionally assigned to the artifi cial taxa “Acteon” and “Retusidae” until anatomical data become available. The present collecting effort in the southwest Pacifi c has produced large numbers of previously undocumented species. The largest number of species was found in the area comprising the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna, which is probably a consequence of a greater collecting effort. The list of species refl ects a high degree of endemism in the deep sea fauna from the southwest Pacifi c. Only a few widespread Indo-Pacific species have been found in the deep sea. It also appears that there is some sort of isolation between the Coral Sea, New Caledonia, Vanuatu, Fiji, Tonga and Wallis and Futuna region and the Philippines and Indonesia region, which is refl ected in the small number of species shared between these two areas. Most species of “cephalaspidean” heterobranchs studied here have broad bathymetric ranges compared to other groups of opisthobranchs, which may be a result of a higher ecological adaptability of this group, or may be an artifact caused by transport of empty shells. When only specimens collected alive are considered, the bathymetric ranges of most species are considerably narrower. Most species studied are exclusively found in the deep sea, but a small number of shallow water species have been recorded here for the fi rst time in deep waters. When the ranges of empty shells are examined there appears to be a turnover of “cephalaspidean” heterobranch species at about 1000-1200 m depth and a blurry transition between shallow waters and the deep sea. When only specimens collected alive are considered, there is a sharp boundary at about 200 m that clearly separates the shallow water and the deep sea faunas. “Cephalaspidean” heterobranch species are more common relative to other groups of opisthobranchs in deep waters than in shallow waters, but this result may be an artefact caused by the collecting techniques.

doi: 10.1111/j.1096-3642.2008.00492.x Résumé [+] [-]The family Galatheidae is among the most diverse families of anomuran decapod crustaceans, and the South-West Pacific is a biodiversity hot spot for these squat lobsters. Attempts to clarify the taxonomic and evolutionary relationships of the Galatheidae on the basis of morphological and molecular data have revealed the existence of several cryptic species, differentiated only by subtle morphological characters. Despite these efforts, however, relationships among genera are poorly understood, and the family is in need of a detailed systematic review. In this study, we assess material collected in different surveys conducted in the Solomon Islands, as well as comparative material from the Fiji Islands, by examining both the morphology of the specimens and two mitochondrial markers (cytochrome oxidase subunit 1, COI, and 16S rRNA). These two sources of data revealed the existence of eight new species of squat lobster, four of which were ascribed to the genus Munida, two to the genus Paramunida, one to the genus Plesionida, and the last species was ascribed to the genus Agononida. These eight species are described along with phylogenetic relationships at the genus level. Our findings support the taxonomic status of the new species, yet the phylogenetic relationships are not yet fully resolved. Further molecular analysis of a larger data set of species, and more conserved genes, will help clarify the systematics of this group.

Résumé [+] [-]Based on part of the material collected during the HALIPRO 1, BATHUS 3, BATHUS 4, and NORFOLK 2 expeditions by the Muséum national d’Histoire naturelle, Paris off New Caledonia, 10 species of scleractinian corals belonging to the genus Deltocyathus were identified: D. magnifi cus, D. rotulus, D. suluensis, D. vaughani, D. ornatus, D. heteroclitus, D. corrugatus, D. crassiseptum, D. cameratus and D. inusitatus n. sp. These 10 species are fully described and illustrated, their distributional and bathymetric ranges are given. A brief history and an identification key for all species belonging to this genus are provided.

Résumé [+] [-]A new classification is presented based on the results of the recently completed cladistic analysis of the Pylochelidae. The subfamilies Pylochelinae and Pomatochelinae are retained, the latter with the genera Pylocheles and Cheiroplatea; however, the subgenera Xylocheles and Bathycheles are elevated to generic rank together with the nominal subgenus Pylocheles. In addition, one new species, B. phenax, is described in Bathycheles and B. profundus is shown to be conspecific with B. integer. The subfamilies Parapylochelinae, Cancellochelinae, Trizochelinae, and Mixtopagurinae are reduced to ranks of tribes and included in the subfamily Trizochelinae. A new genus Forestocheles is proposed in the tribe Trizochelini. Within the genus Trizocheles, subspecific rank for T. spinosus bathamae is deemed unjustified and this taxon is placed in synonymy with the nominal subspecies T spinosus spinosus. The correct identity of Trizocheles balssi is established and the species mistakenly thought to represent that taxon is described as T. hoensonae, new species. Trizocheles gracilis is found to be conspecific with T. boasi and an additional new species, T. mendanai, is added to the genus. The superfamilial ranks of Cheiroplateoidea, Pomatocheloidea, Pylocheloidea, and Cancellocheloidea proposed by Watabe (2007) are rejected, as is Birgusoidea.

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

doi: 10.1080/14772000903571088 Résumé [+] [-]The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.
Macpherson, Enrique, Richer de Forges, Bertrand, Schnabel, Kareen, Samadi, Sarah, Boisselier, Marie-Catherine, Garcia-Rubies, Antoni, 2010, Biogeography of the deep-sea galatheid squat lobsters of the Pacific Ocean, Deep Sea Research Part I: Oceanographic Research Papers, 57, 2, 228-238
doi: 10.1016/j.dsr.2009.11.002 Résumé [+] [-]We analyzed the distribution patterns of the galatheid squat lobsters (Crustacea, Decapoda, Galatheidae) of the Pacific Ocean. We used the presence/absence data of 402 species along the continental slope and continental rise (200-2000 m) obtained from 54 cruises carried out in areas around the Philippines, Indonesia, Solomon, Vanuatu, New Caledonia, Fiji, Tonga, Wallis and Futuna and French Polynesia. The total number of stations was ca. 3200. We also used published data from other expeditions carried out in the Pacific waters, and from an exhaustive search of ca. 600 papers on the taxonomy and biogeography of Pacific species. We studied the existence of biogeographic provinces using multivariate analyses, and present data on latitudinal and longitudinal patterns of species richness, rate of endemism and the relationship between body sizes with the size of the geographic ranges. Latitudinal species richness along the Western and Eastern Pacific exhibited an increase from higher latitudes towards the Equator. Longitudinal species richness decreased considerably from the Western to the Central Pacific. Size frequency distribution for body size was strongly shifted toward small sizes and endemic species were significantly smaller than non-endemics. This study concludes that a clear separation exists between the moderately poor galatheid fauna of the Eastern Pacific and the rich Western and Central Pacific faunas. Our results also show that the highest numbers of squat lobsters are found in the Coral Sea (Solomon-Vanuatu-New Caledonia islands) and Indo-Malay-Philippines archipelago (IMPA). The distribution of endemism along the Pacific Ocean indicates that there are several major centres of diversity, e.g. Coral Sea, IMPA, New Zealand and French Polynesia. The high proportion of endemism in these areas suggests that they have evolved independently. (C) 2009 Elsevier Ltd. All rights reserved.

Peñas, Anselmo, Rolán, Emilio, Gofas, Serge, 2010, Deep water Pyramidelloidea of the Tropical South Pacific: Turbonilla and related genera, Mémoires du Muséum national d'Histoire naturelle, 26, 200
Résumé [+] [-]This paper reports on deep water Pyramidellidae from the tropical South Pacific, collected during the Tropical Deep-Sea Benthos expeditions conducted by IRD and MNHN in New Caledonia, the Solomon Islands, Fiji, Tonga, Vanuatu, Wallis and Futuna, and French Polynesian, and deals more specifically with those species that can be included in the tribe Turbonillini. Since the different genera have not been thoroughly revised at the present time and there is no certainty about their validity, we have employed only the genus name Turbonilla in a broad sense. In total, 272 species are studied, of which 30 were already known, 33 were too poorly represented to be named and are presented as sp., and 209 are described as new to science. There is a clear decrease in species richness from the Solomon Islands (202 species) eastwards to Fiji (82 species), New Caledonia (85 species), Vanuatu (31 species), Tonga (11 species) and the Marquesas (7 species). Replacement names are proposed for Turbonilla gracilis (A. Adams, 1854) non Turbo gracilis Brocchi, 1814, and Exesilla sulcata Laseron, 1959, non Odostomia sulcata Garrett, 1873, both secondary homonyms in Turbonilla. New taxonomic opinions in this work are the following: Turbonilla theresa Thiele, 1925 and Pyrgiscus mirandus Saurin, 1959 are considered synonyms of Turbonilla funiculata de Folin, 1868; Odontostomia robusta Hedley, 1899, Turbonilla microscopica Laseron, 1959, and Turbonilla (Pyrgostelis) manorae Melvill, 1898 are considered synonyms of Turbonilla mumia (A. Adams, 1861); Turbonilla decussata Pease, 1861, T. elongata Pease, 1868, Proto cornelliana Newcomb, 1870, Chemnitzia coppingeri E. A Smith, 1884, Turbonilla (Lancella) bella Dall & Bartsch, 1906, and Turbonilla (Lancella) vitiensis Pilsbry, 1917 are considered synonyms of Turbonilla varicosa (A. Adams, 1855); Elusa secunda Saurin, 1959 is a synonym of Turbonilla ovalis de Folin, 1868; Turbonilla multigyrata Dunker, 1882 is a synonym of T. candida A. Adams, 1855; Turbonilla lydia Thiele, 1925 is a synonym of Turbonilla crystallina Dall & Bartsch, 1906.
Puillandre, Nicolas, Sysoev, Alexander V., Olivera, Baldomero M., Couloux, Arnaud, Bouchet, Philippe, 2010, Loss of planktotrophy and speciation: geographical fragmentation in the deep-water gastropod genus Bathytoma (Gastropoda, Conoidea) in the western Pacific, Systematics and Biodiversity, 8, 3, 371-394
doi: 10.1080/14772001003748709 Résumé [+] [-]Dispersal capabilities are crucial in how speciation patterns are determined in marine invertebrates. Species possessing a long-living planktonic larva apparently have a dispersal advantage over those with non-planktotrophic development, and their distant populations may exchange genetic material, maintaining a broad geographical range for the species. Recent species of the gastropod genus Bathytoma (Conoidea) are all characterized by non-planktotrophic development, having most probably lost a free-swimming larva in the pre-Pliocene, as Miocene fossils have protoconchs indicating planktotrophic larval development. All have a bathyal distribution (100–1500 m), which implies that their capability for direct expansion on the bottom is restricted by both deep-sea basins and shallow-water areas, especially in insular West and South-West Indo-Pacific. Therefore, it can be hypothesized that Bathytoma populations should represent numerous, mostly allopatric taxa restricted to a single or contiguous island groups. We tested this hypothesis using molecular and morphological characters independently. One hundred and thirty-eight specimens from the Philippines, Solomons, Vanuatu, and the Coral Sea were sequenced for one mitochondrial (COI) and one nuclear (ITS2) gene, and 14 operational molecular units were recognized. When these molecular units are overlaid over shell characters, 13 species (11 unnamed) and one form of uncertain status are recognized: three occur in the Philippines, six in the Solomons and one in New Caledonia. Broad distributions (inter-archipelagic) are uncommon (three species). On the whole, the phylogeographic pattern of the diversity in the genus is rather complex and probably also reflects processes of sympatric and fine-scale allopatric speciation, and local extinctions. The eleven new species are described and named.
De Grave, Sammy, Fransen, Charles H. J. M., 2011, Carideorum catalogus: the recent species of the dendrobranchiate, stenopodidean, procarididean and caridean shrimps (Crustacea: Decapoda), Zoologische Mededelingen, 85, 9
Résumé [+] [-]Over the last decade or so, much has been written on the classification of Decapoda, fuelled by a surge in molecular phylogenetic studies, as well as close scrutiny of internal and external morphological characteristics. As discussed by Fransen & De Grave (2009), such studies on shrimps are still somewhat ”thin on the ground”, at least compared to the more extensive work done on the Brachyura and Anomura. At a higher level in decapod classification it has long been recognised that three distinct lineages of shrimps can be distinguished: Dendrobranchiata, Stenopodidea and Caridea, a system which has not been seriously challenged by recent studies. The internal classification of Dendrobranchiata and Stenopodidea alike has been stable for some time, with the only major addition being the family Macromaxillocarididae Alvarez, Iliffe & Villalobos (2006) to the Stenopodidea in recent years. A different picture has emerged for Caridea very recently with Bracken et al. (2009) and Chan et al. (2010), both drawing attention to the non-monophyletic status of certain superfamilies and families. Further, we are aware of work currently in progress (some by the authors of this compilation) corroborating the hypothesis that the current classification of Caridea is unnatural, lines of study which will lead to the resurrection of certain family names as well as further refinement to other families. As one of our objectives for the current effort was to link this compilation of species level information with the earlier work by Chace (1992) for families and Holthuis (1993a) for genera, we have elected to largely follow the classification outlined by De Grave et al. (2009) which builds upon this earlier work. As such, it was deemed advisable to include the recently resurrected family Acanthephyridae Spence Bate, 1888 in the superfamily Oplophoroidea, rather than in this catalogue to create a new superfamily, which would perhaps be more congruent with the results in Chan et al. (2010). Although we follow herein the classification scheme of De Grave et al. (2009), two recent changes have been implemented. The clarification of the status of Galatheacaris abyssalis Vereshchaka, 1997a, as the megalopal stage of Eugonatonotus chacei Chan & Yu, 1991a, by De Grave et al. (2010) resulted in the removal of the family Galatheacarididae and superfamily Galatheacaridoidea in the current listing. Bracken et al. (2010) clarified the status of the family Procarididae, resulting in the recognition of a fourth group of shrimp, Infraorder Procarididea.
O'Hara, Timothy D., Rowden, Ashley A., Bax, Nicholas J., 2011, A Southern Hemisphere Bathyal Fauna Is Distributed in Latitudinal Bands, Current Biology, 21, 3, 226-230
doi: 10.1016/j.cub.2011.01.002 Résumé [+] [-]The large-scale spatial distribution of seafloor fauna is still poorly understood. In particular, the bathyal zone has been identified as the key depth stratum requiring further macro- ecological research [ 1 ], particularly in the Southern Hemi- sphere [ 2 ]. Here we analyze a large biological data set derived from 295 research expeditions, across an equator- to-pole sector of the Indian, Pacific, and Southern oceans, to show that the bathyal ophiuroid fauna is distributed in three broad latitudinal bands and not primarily differentiated by oceanic basins as previously assumed. Adjacent faunas form transitional ecoclines rather than biogeographical breaks. This pattern is similar to that in shallow water despite the order-of-magnitude reduction in the variability of environmental parameters at bathyal depths. A reliable biogeography is fundamental to establishing a representative network of marine reserves across the world’s oceans [1, 3].

doi: 10.5252/z2011n2a4 Résumé [+] [-]Material previously identified as Galearctus kitanoviriosus (Harada, 1962) from New Caledonia has been found to consist of two distinct species. These species differ in the shape of the gastric tooth, third pereiopod propodus, antennal segment IV and thoracic sternum. The shallow water form is the true G. kitanoviriosus, while the deep-water form is new to science. Genetic comparison of the sequence of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), also supports the separation.

doi: 10.1111/j.1558-5646.2011.01560.x Résumé [+] [-]The diversification of Indo-Pacific marine fauna has long captivated the attention of evolutionary biologists. Previous studies have mainly focused on coral reef or shallow water-associated taxa. Here, we present the first attempt to reconstruct the evolutionary historyphylogeny, diversification, and biogeographyof a deep-water lineage. We sequenced the molecular markers 16S, COI, ND1, 18S, and 28S for nearly 80% of the nominal species of the squat lobster genus Paramunida. Analyses of the molecular phylogeny revealed an accelerated diversification in the late OligoceneMiocene followed by a slowdown in the rate of lineage accumulation over time. A parametric biogeographical reconstruction showed the importance of the southwest Pacific area, specifically the island arc of Fiji, Tonga, Vanuatu, Wallis, and Futuna, for diversification of squat lobsters, probably associated with the global warming, high tectonic activity, and changes in oceanic currents that took place in this region during the OligoceneMiocene period. These results add strong evidence to the hypothesis that the Neogene was a period of major diversification for marine organisms in both shallow and deep waters.

doi: 10.5252/z2012n2a13 Résumé [+] [-]During two cruises to Vanuatu, MUSORSTOM 8 (September-October 1994) and SANTO 2006 (September-October 2006), numerous specimens of deep-sea galatheids belonging to the genus Galathea Fabricius, 1793 were collected. The specimens were caught at stations at depths between 180 and 702 m. These collections contain five new species (G. barbellata n. sp., G. echinata n. sp., G. profunda n. sp., G. raventosae n. sp. and G. sanctae n. sp.), all of which are also found in other collections obtained by French cruises to New Caledonia. Galathea barbellata n. sp., G. echinata n. sp. and G. profunda n. sp. are closely related to G. robusta Baba, 1990, from Madagascar, G. raventosae n. sp. resembles G. consobrina De Man, 1902, from Indonesia, the Philippines, South China Sea and SW Australia, and G. sanctae n. sp. is very close to G. multilineata Balss, 1913, from Japan, East China Sea, Taiwan and the Philippines.

doi: 10.5252/z2012n2a9 Résumé [+] [-]Four new skates of the genus Notoraja Ishiyama, 1958 are described from the rarely accessed, deep waters off New Caledonia, Vanuatu and Fiji islands, and the Norfolk Ridge. Three of these (N. alisae n. sp., N. longiventralis n. sp. and N. fijiensis n. sp.) are “velcro skates” which are characterised by their velvety dorsal and ventral surfaces, covered with fine denticles. Although similar in shape, they differ by their colour pattern, dermal armature, development of the lateral tail folds, and size of the pelvic-fin anterior lobe and nasal curtain. The description of the fourth species, Notoraja inusitata n. sp., is based on a juvenile male exhibiting some unusual features resembling those of other skate genera.

Résumé [+] [-]Litozamia acares n. sp. and Siphonochelus (Trubatsa) wolffi n. sp. are described from New Caledonia. The radula and the operculum of Litozamia acares are illustrated and described. The classification of Litozamia in Trophoninae is maintained awaiting molecular data to either confirm or modify this decision. Litozamia longior (Verco, 1909) is reinstated as a valid species. The use of the subgenus Choreotyphis Iredale, 1936 is reinstated in Siphonochelus for a single species from eastern Australia, based on differences in shell morphology.

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

Résumé [+] [-]Recent French deep-sea expeditions in the Indo-West Pacific resulted in the collection of abundant material of the deep-sea lobster genus Puerulus Ortmann, 1897 (Palinuridae). Difficulties in identification necessitated a generic revision and as a result, five new species are described, all of which are similar to P. angulatus (Bate, 1888). Puerulus angulatus was thought to have a wide distribution from eastern Africa to Marquesas Islands, but is now restricted to the western Pacific, from Japan to Australia. Of the five new species, P. gibbosus n. sp. is found in eastern Africa, P. mesodontus n. sp. from Japan to Fiji, P. richeri n. sp. from the New Caledonia to Marquesas Islands, while P. sericus n. sp. and P. quadridentis n. sp. mainly occur around New Caledonia. Of the other three previously described species, the distribution of P. velutinus Holthuis, 1963, is extended to Fiji, while P. sewelli Ramadan, 1938, and P. carinatus Borradaile, 1910, are still only known from the northern and western parts of the Indian Ocean, respectively. COI gene sequence differences support the morphological species distinctions.
Chang, Su-Ching, Chan, Tin-Yam, Ahyong, Shane T., 2014, Two new species of the rare lobster genus Thaumastocheles Wood-Mason, 1874 (Reptantia: Nephropidae) discovered from recent deep-sea expeditions in the Indo-West Pacific, Journal of Crustacean Biology, 34, 1, 107-122
doi: 10.1163/1937240X-00002201 Résumé [+] [-]Specimens of species closely related to the rare deep-sea lobster Thaumastocheles japonicus Calman, 1913 were obtained from recent deep-sea expeditions in the West Pacific. Close examination of these specimens, as well as molecular analysis, showed that they represent two species new to science, with many morphological and significant genetic differences (barcoding gene COI sequence divergences 11.5- 14.8%) between each other as well as T. japonicus. Re-examination of the specimens previously assigned to T. japonicus revealed that true T. japonicus has a more northern distribution, from Japan to the South China Sea and the Philippines. The two new species have more southern distributions with T. bipristis n. sp. Restricted to the Philippines and Indonesia, and T. massonktenos n. sp. Being widely distributed in the Indo-West Pacific, from the South China Sea to Madagascar and New Caledonia. The genetic data also suggest that T. dochmiodon Chan and de Saint Laurent, 1999 may represent a polymorphic male form of T. japonicus.
Lemaitre, Rafael, 2014, A worldwide taxonomic and distributional synthesis of the genus Oncopagurus Lemaitre, 1996 (Crustacea: Decapoda: Anomura: Parapaguridae), with descriptions of nine new species, The Raffles Bulletin of Zoology, 62, 210–301
Résumé [+] [-]A worldwide taxonomic and distributional synthesis of the deep-water hermit crab genus Oncopagurus Lemaitre, 1996 is presented. This genus, originally defined for 10 species is set apart from other Parapaguridae as well as other Paguroidea, by one synapomorphy: the presence of an upwardly curved epistomial spine. This study is based on a large amount of specimens deposited in major museums and collected during deep-sea sampling across the world oceans since the late 1800s, with the bulk of material coming from French campaigns in the Indo-Pacific, central and south Pacific during the last 40 years. A total of 24 species are recognised in this investigation, nine of which are new and fully described and illustrated. All previously known species are diagnosed or re-described, including figures assembled from recent published accounts or newly illustrated, of the most important morphological features useful for identifi cations. Information for each species includes a synonymy (full or abbreviated if a synonymy has recently been published), material examined (type and non-types), variations when signifi cant, colouration when available, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Rare colour photographs are included for five species. Species of Oncopagurus range in depth from the Continental Shelf (50 m) to the Continental Rise (2308 m), although they are most commonly found in 50–500 m. Individuals of the majority of species in this genus are minute in size (< 3 mm in shield length), species differ in subtle morphological characters, and often exhibit the same broad morphological variations related to sex and size that has been documented in species of other genera of Parapaguridae. Oncopagurus mironovi Zhadan, 1997, a taxon reported from the Nazca and Sala-y-Gómez Ridges, is considered a junior synonym of the widely distributed O. indicus (Alcock, 1905). The bathymetric and geographic distributions of Oncopagurus species are summarised and briefly discussed, complemented with a summary table, graph, and map with generalised distribution patterns. The scant phylogenetic knowledge of this genus is summarised.

doi: 10.1007/s10709-014-9807-0 Résumé [+] [-]During the past decade, a large number of multi-gene analyses aimed at resolving the phylogeneticrelationships within Decapoda. However relationships among families, and even among sub-families, remain poorly defined. Most analyses used an incomplete and opportunistic sampling of species, but also an incomplete and opportunistic gene selection among those available for Decapoda. Here we test in the Caridea if improving the taxonomic coverage following the hierarchical scheme of the classification, as it is currently accepted, provides a better phylogenetic resolution for the inter-families relationships. The rich collections of the Muse´um National d’Histoire Naturelle de Paris are used for sampling as far as possible at least two species of two different genera for each family or subfamily. All potential markers are tested over this sampling. For some coding genes the amplification success varies greatly among taxa and the phylogenetic signal is highly saturated. This result probably explains the taxon-heterogeneity among previously published studies. The analysis is thus restricted to the genes homogeneously amplified over the whole sampling. Thanks to the taxonomic sampling scheme the monophyly of most families is confirmed. However the genes commonly used in Decapoda appear non-adapted for clarifying inter-families relationships, which remain poorly resolved. Genome-wide analyses, like transcriptome-based exon capture facilitated by the new generation sequencing methods might provide a sounder approach to resolve deep and rapid radiations like the Caridea.

doi: 10.11646/zootaxa.3913.1.1 Résumé [+] [-]The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other collections from various sources, and including the type specimens of some previously described species. Most of the new species are distinguished by subtle but constant morphological differences, which are in agreement with molecular divergences of the mitochondrial markers COI and/or 16S rRNA. Here, we describe and illustrate the new species and redescribe some previously described species for which earlier accounts are not sufficiently detailed for modern standards. Furthermore we include a dichotomous identification key to all species in the genus from the Indian and Pacific Oceans.

Résumé [+] [-]The tropical deep-water Cominellinae commonly assigned to the genera Manaria E. A. Smith, 1906 and Eosipho Thiele, 1929 are revised. While the taxonomic details at the generic level were discussed by Kantor et al. (2013), the species level is discussed here. Twentyone new species are described: Manaria astrolabis n. sp. (French Polynesia), M. borbonica n. sp. (Réunion), M. circumsonaxa n. sp. (Papua New Guinea and the Solomons), M. corindoni n. sp. (Indonesia), M. corporosis n. sp. (the Solomons, Vanuatu, Coral Sea and New Caledonia), M. explicibilis n. sp. (Papua New Guinea and the Solomons), M. excalibur n. sp. (Indonesia and Western Australia), M. fluentisona n. sp. (the Solomons, Fiji, Wallis and Tonga), M. hadorni n. sp. (Papua New Guinea and New Caledonia), M. indomaris n. sp. (India), M. loculosa n. sp. (Fiji), M. lozoueti n. sp. (North Fiji Basin), M. terryni n. sp. (Mozambique Channel), M. tongaensis n. sp. (Tonga), M. tyrotarichoides n. sp. (Mozambique Channel), Calagrassor bacciballus n. sp. (Philippines), C. delicatus n. sp. (New Zealand), C. hespericus n. sp. (Mozambique), C. pidginoides n. sp. (Philippines, Papua New Guinea, the Solomons and Vanuatu), Enigmaticolus marshalli n. sp. (Kermadec Ridge, Monowai Caldera), and E. voluptarius n. sp. (New Caledonia). Considerable range extensions are recorded: Manaria kuroharai Azuma, 1960 is recorded from the Solomons, New Caledonia, Vanuatu and Tonga; M. brevicaudata (Schepman, 1911) is recorded from Taiwan, the Philippines, the Solomons and Fiji; and Calagrassor poppei (Fraussen, 2001) is recorded from Indonesia and the Solomons. Lathyrus jonkeri Koperberg, 1931, a fossil described from Indonesia, is recorded from the Recent fauna of Indonesia, Philippines and Fiji and is redescribed and placed in Manaria. Sipho jonkeri Koperberg, 1931, another fossil described from Indonesia in the same work, is a secondary homonym of Manaria jonkeri (Koperberg, 1931) and is renamed Manaria koperbergae nom. nov.
