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

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

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

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.

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

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.

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.

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

The Macroramphosid fish Notopogon xenosoma Regan 1914 is recorded on the northern part of the Norfolk ridge and the southern shelf of New Caledonia from ORSTOM trawl surveys. It becomes the most northernly distribuuon m the south-west Pacific Ocean for this subtropical species. Other specimens have been identified from Madagascar collections and induces the same conclusion for the south-west Indian Ocean.

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.

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.

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

In comparison with other ecosystems, biodiversity and natural-product diversity of the New Caledonian marine ecosystem, comprising lagoons, barrier reefs, and deep waters in seamount regions, are described here phylogenetically with the aid of molecular drawings and tabulation of data. Admittedly, since the inception of these studies in 1977, the comparison is biased by selection of New Caledonian organisms on the basis of positive pharmacologically oriented bioassays. However, we show that these and other distortions must be accepted to draw any comparison on a regional basis, which, nonetheless, turn out to be useful for the progress of knowledge, particularly in directing future explorations of biodiversity in the search for new pharmacologically active metabolites.

A large collection of species of the genus Munida has been examined and found to contain 56 undescribed species. The specimens examined were caught mainly off New Caledonia, Chesterfield Islands, Loyalty Islands, Matthew and Hunter Islands. Several samples from Kiribati, the Philippines and Indonesia have also been included. The specimens were collected between 6 and 2 049 m. Some species previously known in the area (Af. Gracilis, M. haswelli, M. microps, M. spinicordata and M. tubercidata) have been illustrated. These results point up the high diversity of this genus in the region and the importance of several characters in species identification (e.g., size and number of lateral spines on the carapace, ornamentation of the thoracic sternites, size of antennular and antennal spines, colour pattern).

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.

Recent expeditions to Rapa Nui (also known as Easter Island) and New Caledonia have revealed undescribed species from mesophotic and deeper depths. This includes three new species from Rapa Nui, Hacelia raaraa, Linckia profunda (Ophidiasteridae), Uokeaster ahi (Asterodiscididae) and two new species from New Caledonia, Astroglypha pyramidata n. gen. and Ophidiaster colossus (Ophidiasteridae). The new genus Astroglypha is described for A. pyramidata but the genus also includes the Atlantic Tamaria passiflora, which is reassigned herein. Pauliastra n. gen. is designated as a replacement for the homonym issue with Pauliella. New occurrences and synonymies are addressed for taxa related to New Caledonia, Rapa Nui and adjacent regions. A morphology based phylogenetic analysis agrees with prior work which placed Goniaster among the Asterodiscididae and posits biogeographic relationships among asterodiscidid genera. Implications for the Goniasteridae and placement of Goniaster among asterodiscidid genera are discussed. Biogeography and relationships among taxa from Rapa Nui and New Caledonia are reviewed. In situ observations from species observed from Rapa Nui are included.

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.

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

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].

A rapid panorama of the deep sea fauna knowledge, deeper than 100 m, is shown, positioning the specific richness and sampling New Caledonia effort in the Indo-Pacific. A detailled presentation of the french exploration oceanographic cruises is done. Since 1984, no less than 1468 benthic samples in the New Caledonia EEZ have been done. All these data are now integrated in the "Océane" database at IRD Center in Noumea. This document give an inventory of 2515 deep sea species from New Caledonia, presented by zoological groups and families by alphabetic order. 1322 new species were described from New Caledonia (52.5%). ln annexe is given: a complete list of references corresponding to the description of this fauna and the list of taxonomists involved (155 scientists from 21 countries); the bathymetric maps of the main seamounts.

Fourty-nine species of Pycnogonida (and six unidentifiable forms) are recorded from the continental slope (200-3740 m) in the Western Pacific off New Caledonia, the Loyalty and Chesterfield Islands, and in the Lau Basin ; only six samples originate from the continental shelf (40-73 m). Of these 49 species, not less than 33 (67 %) are new to Science. The new species belong to the genera Ascorhynchus (3 spp.), Ammothella (1 sp.), Heterofragilia (1 sp.), Cilunculus (4 spp.), Proboehmia gen. Nov. (1 sp.), Sericosura (1 sp.), Rhopalorhynchus (1 sp.), Colossendeis (1 sp.), Hedgpelhia (1 sp.), Austrodecus (5 spp., of which 4 attributed to a new subgenus, Tubidecus), Nymphon (4 spp.), Seguapallene (1 sp.), Parapallene (1 sp.), Pallenopsis s. str. (1 sp.), Pallenopsis (Bathypallenopsis) (1 sp.), Phoxichilidium (2 spp.). Anoplodactylus (1 sp.), and Pycnogonum (3 spp.). The richness in new species is explained by the fact that the bathyal zone around New Caledonia was unexplored so far for Pycnogonida.

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.

Delineating biogeographical regions can provide important insights into the processes shaping large‐scale species distribution patterns. Here we aimed to 1) identify global marine benthic biogeographical regions for ophiuroids extending from shallow waters to the deep sea and 2) quantify the importance of contemporary environmental conditions and geological features in shaping the delineated biogeographical regions. We delineated marine benthic biogeographical regions using a bipartite network analysis applied to a historical dataset of brittle stars. We then examined the faunal exchanges between the regions, and applied random forest models to evaluate the relative role of contemporary environmental conditions and tectonic configuration underlying the proposed biogeographic scheme. We propose ten main large biogeographical regions across the benthos. The biogeographical regions with the highest species richness and endemicity rates were found in the Indo‐Pacific region, Tropical West Atlantic and Southern Ocean, and South America. The key transition regions fall within the subarctic areas of the Pacific and the waters surrounding Southern Australia and New Zealand. Tectonic configuration, surface temperature and salinity were found to be the most important predictors of the ten delineated biogeographical regions. Our biogeographic delineation, including the deep sea, is in partial agreement with those proposed in previous studies. Our results suggest that contemporary environmental conditions (sea water temperature and salinity) strongly influence the modern distribution of ophiuroids, but that plate tectonics left a marked imprint on regional species pools. Future work based on multiple benthic taxa, and with a better understanding of the environmental conditions in the deep sea, are needed to evaluate the robustness of our proposed division.
