Houart, Roland, 1988, Description of seven new species of Muricidae (Neogastropoda) from the south-western Pacific Ocean, Venus (Japanese journal of Malacology), 47, 3, 185-196
Résumé [+] [-]Seven new muricid species are described from New Caledonia and from the Chesterfield reefs in the Coral Sea. Chicoreus paucifrondosus n. sp. and C. subpalmatus n. sp. are both compared with C. boucheti Houart, 1983; Pterynotus levi n. sp. and P. fulgens n. sp., the first deep-water Pterynotus species described from New Caledonia, are both compared with P. laetifica flemingi Beu, 1967 from New Zealand. Ponderia caledonica n. sp. and P. magna n. sp. are two supplementary species to include in the recently named Ponderia Houart, 1986 and are both compared with the other species of this genus; Muricopsis metivieri n. sp. is related to certain Japanese species tentatively grouped in the subgenus Murexsul Iredale, 1915. All the new species have paucispiral protoconchs.
Cleva, Régis, Crosnier, Alain, 1990, Crustacea Decapoda : les genres et les espèces indo-ouest pacifiques de Stylodactylidae, Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 6, 145, 71-136
Résumé [+] [-]Numerous samples of Stylodactylidae collected between 1976 and 1989 off the Philippines, New Caledonia and Chesterfield Islands (MUSORSTOM, BIOCAL, CHALCAL, CORAIL 2 a n d SMIB cruises) are studied here. Other collections from Indonesia (CORINDON 2 cruise), Madagascar (coll. A. CROSNIER and R. CLEVA), and la Réunion (« MARION DUFRESNE », cruise M D 32) are included. This material is of particular interest since many specimens of various taxa have been collected : eighteen species and subspecies have been identified in it, of which nine are new : three species and one subspecies in the genus Stylodactylus. four species in the genus Parastylodactylus, and one in the new genus Stylodactyloides. Nine species and one subspecies of the genus Stylodactylus A. Milne Edwards, 1881., are represented in the collections studied here. S. laurentae sp. nov., with its typically short rostrum, seems to be one of the most common shrimps of the genus in New Caledonia and Chesterfield Islands. S. profundus sp. nov., unfortunately represented by specimens in incomplete or poor condition, extends the bathymetric range of the family : it has been collected, off New Caledonia, between 1395-1410 and 1618-1740 m. S. brevidactylus sp. nov. is represented by a single specimen from the Philippines : we at first considered that this specimen was an aberrant example of S. multidentatus Kubo, 1942, but decided then to re-examine our opinion because of its peculiar characters. Twenty seven specimens (eleven from the Philippines and sixteen from Chesterfield Islands and New Caledonia) have been identified as S. licinus Chace, 1983, a little known species described from the Philippines, and eleven others (one from Indonesia and ten from New Caledonia and Chesterfield Islands) as S. tokarensis Zarenkov, 1968, only known by the holotype collected in the east China sea (the paratype of S. tokarensis is suspected of being a specimen of S. licinus Chace). S. multidentatus Kubo, 1942, is probably one of the most commonly caught species of the family. Many specimens have been collected by the french campaigns from the Philippines, New Caledonia, and Madagascar : Neocaledonian specimens differ from the former by a longer rostrum and longer spines on the margin of the antennal scale. These differences are still more accentuated in Madagascarian specimens, and we finally decided to create for them a new subspecies, S. multidentatus robustus. Two other species of Stylodactylus are represented in our material : S. macropus Chace, 1983, of which the only previouly known specimen was collected by the « ALBATROSS » in the Philippines, is reported here, again from the Philippines and from New Caledonia and Chesterfield Islands. S. libratus Chace, 1983, described from a single specimen from Indonesia (Celebes, « ALBATROSS » collection) and reported then from Australia (New South Wales) by KENSLEY, TRANTER and GRIFFIN (1987) has been collected in New Caledonia and Chesterfield Islands. One specimen from Madagascar appears to be very close to S. libratus but shows however some différences from it, so that we identify it as S. aff. libratus. The genus Neostylodactylus Hayashi & Miyake, 1968, is represented in our material by two species : N. amarynthis (de Man, 1902), and N. affinis Hayashi & Miyake, 1968 : in these two species we have noted the very particular sexual dimorphism mentioned by CHACE (1983 : 6) for N. amarynthis : females differ from maies in lacking arthrobranchs on pereiopods 1 to 4. The geographical distribution of N. amarynthis extends now, in the Indo-Pacific, to the southwestern Indian Océan (La Réunion), and that of N. affinis, previously known only from the Korea Strait at 120 m depth, is shown to belong to the New Caledonia and Chesterfield Islands fauna ; it has been caught between 235 and 440 m. Four new species have been included in the genus Parastylodactylus created by FIGUEIRA in 1971 for Stylodactylus bimaxillaris Bate, 1888, and until now monospecific. P. bimaxillaris (Bate), known from a large part of the Indo-Pacific, is mentioned for the first time from New Caledonia and Madagascar. P. tranterae sp. nov., collected off New Caledonia and Chesterfield Islands, was first reported from Australia (New South Wales) by KENSLEY, TRANTER a n d GRIFFIN (1987) who suspected that it was a new species, butdid not name it, on account of the poor condition of the single specimen in their possession. P. semblatae sp. nov. seems to be very common in New Caledonia and Chesterfield Islands. P. richeri sp. nov., from New Caledonia, and P. longidactylus sp. nov., from the Philippines, each represented by a few specimens only, are fairly closely related species, but however are clearly distinct taxa. A new genus, Stylodactyloides, is proposed for a new species collected from New Caledonia and Chesterfield Islands, 5. crosnieri, which has a very unusual stylocerite, broadly rounded distally, which distinguishes it from ail other members of the family. It may be noted that several points in the systematics of the Stylodactylidae remain obscure. These will necessitate the examination of new collections. This work, however, shows the particular interest of these collection, concerning a little known and poorly represented family (nine new taxa described, representing more than one third of the species known until now), and indicates the richness of New Caledonia and Chesterfield Islands waters, where thirteen species have been collected, including six of the nine new ones. Ail the new taxa have been illustrated, and individual variations carefully studied in the species represented by numerous specimens. Color photographs of several species, taken on board during some of these cruises, complété the iconography. Identification keys are proposed for the four généra and twenty six species and subspecies now recognized in the family.

Résumé [+] [-]Some species of Murex and Haustellum are discussed and have their geographical range extended. One species Murex protocrassus, and one subspecies, Haustellum dentifer coriolis, are described from New Caledonia, and one subspecies, Haustellum gallinago fernandesi, is described from Mozambique
Kulbicki, Michel, Randall, John E., Rivaton, Jacques, 1990, Checklist of the Fishes of the Chesterfield Islands (New Caledonia) - Rapport provisoire, 37
Résumé [+] [-]A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduced species. The native fi sh fauna of New Caledonia therefore consists of 2320 species in 241 families. The largest families are the Gobiidae, Labridae, Pomacentridae, Serranidae, Apogonidae, Blenniidae, Macrouridae, Myctophidae and Muraenidae. The freshwater fi sh fauna is dominated by the families Gobiidae, Eleotridae, Anguillidae and Mugilidae. A total of 61 species represent new records from New Caledonia. The fish fauna from New Caledonia includes a total of 125 species occurring in freshwater (plus eight introduced species), 266 (plus two introduced) species in transitional (brackish) waters, and 2320 marine species. The detailed geographical distribution of the New Caldonian fi sh species including the southern submarine ridges (Lord Howe Island, Norfolk Island, New Zealand) is provided. Among the New Caledonian marine species, 905 are recorded from the East Coral Sea including Chesterfi eld Islands, 193 from the New Caledonian basin, 1860 from the Grande Terre group, 85 from the Norfolk Ridge, and 1029 from the Loyalty Ridge including Loyalty Islands. New Caledonia has a considerable endemic element of 107 species (4.6 % of the total native species).

Résumé [+] [-]The geographical distribution of Nautilus macromphalus has until now been considered to be restricted to the New Caledonian and Loyalty reefs. Though drifted shells have been collected as far East as the coasts ot Australia. A trip to the Chesterfield Islands in 1978, located between New Caledonia and Australia gave opportunity to collected, drifting shells which were well preserved with traces of organic matters lnside and one living specimen of Nautilus macromphalus. The collection on the surface of lagoon of this specimen cast a doubt on lts origin but N.O Coriolis , in 1988 caught, whilst trawlling at 500 m depth. Two other specimens of Nautilus macromphalus .. Whilst trawling at 500 m depth, two other specimens of Nautilus macromphalus which supports its range extension westwards to the middle of the Coral Sea.

Résumé [+] [-]Five species of Galatheidae : Alainius crosnieri new genus and new species, Phylladiorhynchus integrirostris (Dana, 1853), P. ikedai (Miyake & Baba, 196S), P. pusillus (Henderson, 188S), and Leiogalathea laevirostris (Balss, 1913), collected from New Caledonia are reported. Phylladiorhynchus antonbruuni Tirmizi & Javed, 1980, is transferred to Munida. Phylladiorhynchus serrirostris (Melin, 1939) is synonymized with P. integrirostris. It is suggested that Phylladiorhynchus caribensis Mayo, 1972, be removed from the genus and eventually placed in a new genus.

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

Résumé [+] [-]The Indo-West-Pacific material previously identified as Eugonatonotus crassus (A. Milne Edwards, 1881) is found to be distinct from the typical form in the tropical Western Atlantic by bearing an extra pair of spines at the fifth abdominal tergite. The new form, named E. chacei sp. nov., is described and a holotype selected from Taiwanese material. The morphological differences between the two species are listed and discussed and their coloration is illustrated.
Chan, Tin‐Yam, Crosnier, Alain, 1991, Crustacea Decapoda: Studies of the Plesionika narval (Fabricius, 1787) group (Pandalidae) with descriptions of six new species, Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 9, 152, 413-461
Résumé [+] [-]Samples collected by ORSTOM (Institut de Recherche Scientifique pour le Developpement en Cooperation), Service Mixte de Contrôle Biologique des Armees (SMCB) and the National Taiwan Ocean University in the Indo-West Pacific (off Madagascar, Seychelles Islands, Taiwan, Philippines, Indonesia, Chesterfield Islands, New Caledonia and Polynesia) as well as others obtained on loan from various museums led to a reexamination of the species belonging to the Plesionika narval group. Fourteen species are recognized of which 6 are new : P. yui from Taiwan, P. echinicola from New Caledonia, P. laurentae from New Caledonia and Eastern Australia, P. flavicauda from New Caledonia and Polynesia, P. rubrior and P. curvata from Polynesia. P. escalilis (Stimpson, 1860) is considered to be a synonym of P. narval. The specimens from the Atlantic identified as STIMPSON'S species by LEMAITRE and GORE (1988) are identified as P. longicauda (Rathbun, 1901). P. narval and P. serratifrons (Borradaile, 1900) are considered as distinct species but so similar that finding reliable characters to separate them is very difficult especially as individual variations are observed. P. narval is presently regarded as living only in the Mediterranean and Eastern Atlantic (from Spain to Cape Verde Islands) but it appears South-West Pacific and with a rather restricted distribution. A key mainly for adults is offered for the identification of the species of this group. As coloration very often seems to be a reliable character for identifying fresh specimens, color photographs are included. Unfortunately it was not possible to obtain information on the coloration of all the species and consequently this character could only be used rarely in the key.
Crosnier, Alain, 1991, Crustacea Decapoda : Les Metapenaeopsis indo-ouest-pacifiques sans appareil stridulant (Penaeidae). Deuxième partie, Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 9, 152, 155-297
Résumé [+] [-]This paper is a continuation of the work published in 1987, in which a group of 10 species and one subspecies of Indo-West Pacific Metapenaeopsis without stridulating organs were treated. The study presented here is based on abundant material supplied by a large number of ORSTOM collections made in the Indo-West Pacific (Madagascar, Seychelles and New Caledonia) and by joint expéditions by ORSTOM and the Muséum national d'Histoire naturelle (MUSORSTOM 1-6, CORINDON, BIOCAL, BIOGEOCAL, CHALCAL 1 and 2 cruises) in the Philippines, Indonesia, New Caledonia and Chesterfield Islands and by the MD 32 cruise in the vicinity of La Réunion, supported by the TAAF (Terres Australes et Antarctiques Françaises). Additional material from the collections of the National Muséum of Natural History, Washington, from several Australian Muséums, as well as from the Muséums of Amsterdam, Leiden, Copenhagen and Frankfürt was also examined. Problems have occurred because of insufficient original descriptions and these have resulted in many errors in the Iiterature. All the type specimens have been re-examined (except for M. gallensis Pearson which is apparently lost), and also most of the specimens cited in the Iiterature. Corrected identifications and distributions are given. Among the species previously described, 18 are recognized as valid, either as species or as subspecies : M. assimilis (de Man, 1920), M. ceylonica Starobogatov, 1972, M. commensalis Borradaile, 1898, M. dalei (Rathbun, 1902), M. distincta (de Man, 1907), M. evermanni (Rathbun, 1906), M. faouzii (Ramadan, 1938), M. gallensis (Pearson, 1905), M. hilarula (de Man, 1911), M. Iamellata (de Haan, 1844), M. mannarensis de Bruin, 1965, M. mogiensis consobrina (Nobili, 1904), M. mogiensis mogiensis (Rathbun, 1902), M. quinquedenta (de Man, 1907), M. tarawensis Racek & Dali, 1965, M. vaillanti (Nobili, 1904), M. velutina (Dana, 1852), M. wellsi Racek, 1967. Six species are considered to be synonyms : M. borradailei (de Man, 1911) = M. commensalis Borradaile, 1898. M. bruini Starobogatov, 1972 = M. mogiensis consobrina (Nobili, 1904). M. caliper Liu & Zhong et al., 1988 = M. velutina (Dana, 1852). M. insona Racek & Dali, 1965 = M. velutina (Dana, 1852). M. perlarum (Nobili, 1905) = M. mogiensis consobrina (Nobili, 1904). M. raceki Starobogatov, 1972 = M. assimilis (de Man, 1920). Fifteen species and 2 subspecies are described as new : M. costata, M. difficilis, M. gaillardi, M. incisa, M. laubieri, M. marquesas, M. menoui, M. mogiensis complanata, M. mogiensis intermedia, M. parahilarula, M. persica, M. propinqua, M. proxima, M. quadrilobata, M. richeri, M. spatulata, M. spiridonovi. A total of 35 species and subspecies (not counting one form described under the name M. aff. Distincta which is probably new) are treated. Thus 46 species and subspecies of Metapenaeopsis lacking stridulating organs are now known to occur in the Indo-West Pacific. Two identification keys are presented : one for males, another for females. They are mainly intended as a guide to the numerous figures included in the paper. Illustrations of the genitalia provide assistance in recognizing the characters used to separate the species. All the petasmata are depicted with lobes both closed and separated. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies high species diversity of the Philippines-Indonesia fauna is evident. Déductions about the biogeography must be regarded with caution because they may reflect differences in sampling effort across the various areas and also because many small species have not been adequately collected. It is of particular interest to note that in the New Caledonian region, where there have been many collections made using a variety of methods, 17 species are known, whereas from the vast Philippines-Indonesia region only 19 have been recorded and only 9 from the whole of Australia. Finally some general considerations on the genus Metapenaeopsis are presented and it is suggested that the species currently assigned to it should perhaps be placed in 2 or 3 genera. An effort has been made to define the groups that might be deserving more formal recognition.
Guerriero, Antonio, Debitus, Cécile, Pietra, Francesco, 1991, On the First Marine Stigmastane Sterols and Sterones Having a 24,25-Double Bond. Isolation from the Sponge Stelletta sp. of Deep Coral Sea, Helvetica chimica Acta, 74, 3, 487-494
Résumé [+] [-]The sponge Stelletta sp. (Astrophorida, Stellettidae), collected at - 700 m in the Coral Sea, is shown to contain sterones and sterols of the stigmastane type with a C(24) = C(25) bond for which there is no precedent in the sea. Structure elucidation of the second abundant of these steroids, stigmasta-4,24(25)-dien-3-one((+)-1), is based on 1D and 2D NMR spectra and chemical transformation to acetate (-)-5. Stigmasta-4,24(25)-diene-3,6-dione ((-)-3), present in trace amounts in the sponge, was obtained in sufficient quantity for NMR study by oxidation of the also present, inseparable, and abundant 4:1 mixture of stigmasta-5,24(25)-dien-3-beta-ol (6) and its 5,6-dihydro derivative 7 (Scheme 1). This oxidation also afforded the ketone analogues (+)-8 and (+)-9, which could be separated, thus making structure elucidation possible. The 6-beta-hydroxystigmasta-4,24(25)-dien-3-one ((+)-4), also present in trace amounts in the sponge, was obtained in sufficient amount for NMR study, together with its C(6) epimer (+)-11, by hydroperoxidation of (+)-8 followed by deoxygenation (Scheme 2). The last trace steroid of the sponge, stigmasta-4,6,24(25)-trien-3-one ((-)-2), was structurally elucidated using limited NMR data and comparison with the other stigmastanes. These stigmastanes, as the only steroids of this sponge, are likely to function as stabilizers of its cell walls; their phytosteroid structure, for a sponge which lives in the dark of deep waters, suggest origin through a complex food chain, possibly followed by bioelaboration in the sponge.

Résumé [+] [-]Twenty five species of polynoid scaleworms were collected from the waters in and around the Chesterfields and Fairway Atolls during the cruise CORAIL 2 of the R/V " Coriolis " in July 1988. Two new genera, Verrucapelma, and Heteralentia, and nine new species, Subadyte chesterfieldensis, Harmothoe turbinata, Harmothoe vesicudenta, Harmothoe spongicola, Verrucapelma retusa, Iphione coriolis, Lepidonotus scanlandi, Lepidonotus spinosus and Lepidonotus permixturus are described. Keys to the polynoid scaleworm fauna of the Chesterfields and Fairways are provided, and all twenty five species are described and illustrated.

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

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

Résumé [+] [-]The collections of the deep water calappid crab genus Mursia at the Muséum national d'Histoire naturelle, assembled between 1971 and 1991 off Madagascar, the Philippines and New Caledonia, have been studied, in addition to material sought from other collections. Fifteen species have been identified, of which four are new : M. a/ricana, M. danigoi, M.flamma and M. musorstomia. The allied genus Platymera, formerly submerged within Mursia, is reinstated as a distinct genus. Ali taxa are described, photographed and illustrated, and a key to their identification is provided.
Guinot, Danièle, 1993, Données nouvelles sur les Crabes primitifs (Crustacea Decapoda Brachyura Podotremata), Comptes Rendus de l'Académie des Sciences, 316, 1225-1232
Résumé [+] [-]Preliminary results concerning three families of the Brachyura Podotremata are presented. In the Dynomenidae, thanks to recent captures in New Caledonia, the genus Paradynomene Sakai is compared to other members of the family. Described or confirmed in the Homolodromiidae are : the presence in the maie of abdominal segments frequently provided with rudimentary pleopods on somites 3-5 and extended by inclined pleura ; in both sexes, the absence of vestigial uropods intercalated dorsally and their replacement by a small platelet inserted ventrally. Three new taxa are described : Homolodromia kai sp. Nov. And Dicranodromia karubar sp. Nov. From Indonesia, D. foersteri sp. Nov. From Chesterfield Islands. The placement of the family Dakoticancridae, only known from North American Cretaceous fossils, in the Podotremata is confirmed (presence ofonepair ofspermathecae), and the numerous peculiarities of the group are discussed.

Résumé [+] [-]Although this paper concerns a large collection of dromiid crabs from the Philippine Islands and New Caledonia, with a few specimens from Indonesia and Hawaii, the opportunity is taken to review and revise most of the genera of the Dromiidae. The basis of the revision involves a much wider range of characters than have been used before. Excessive emphasis on the nature of the female sternal grooves is abandoned, and more attention is paid to relative dimensions and ornamentation of the carapace, arrangement of spines on and around the dactyli of all the legs, fusion of the last two segments of the abdomen, and size of the uropod plates. A new set of characters describing the second antenna and the male abdominal locking mechanism are also used. The impxDrtance of the cheliped epipod character is discussed and is shown to be variable in some genera. A total of 28 genera are defined or redefined and a key to their identification is provided, along with keys to the identification of 99 species in these genera. The following genera are restricted and/or redefined : Cryptodromia Stimpson, 1858, Cryptodromiopsis Borradaile, 1903, Dromia Weber, 1795, Dromidia Stimpson, 1858, Dromidiopsis Borradaile, 1900, Epigodromia (a replacement name for Epidromia Kossmann, 1818, which is preoccupied), Homalodromia Miers, 1884, Paradromia Balss, 1921, Petalomera Stimpson, 1858, and Pseudodromia Stimpson, 1858, resulting in the creation of 10 new genera. Ascidiophilus Richters, 1880, Conchoecetes Stimpson, 1858, Epipedodromia Andre, 1932, Eudromidia Barnard, 1947, Exodromidia Stebbing, 1905, Hemisphaerodromia Barnard, 1954, Hypoconcha Guerin-M6neville, 1854, Speodromia Barnard, 1947, and Sphaerodromia Alcock, 1899, remain unmodified. After the elimination of many synonyms and together with the new material described herein, the Dromiidae now includes 29 genera and 109 species. The generic revision has major implications for the dromiid crabs of, not only the Philippines and New Caledonia but also, the rest of the Indo-Pacific region, Australia, South Africa, and the Atlantic. Until now only six species of dromiid crabs were known from New Caledonia and the Philippine Islands. This number is increased to 29 species belonging to 13 genera. The most common species are Lauridromia intermedia (Laurie, 1906) nov. comb., Petalomera pulchra Miers, 1884, Cryptodromia coronata Stimpson, 1858, Dromidiopsis dubia Lewinsohn, 1984, and Epigodromia areolata (Ihle, 1913) nov. comb. Most of these dromiids come from shallow water, less than 100 m, and the maximum number of sp)ecies occurs in the depth interval of 30-60 m. The greatest depth of 437 m is shown by Frodromia atypica (Sakai, 1936) nov. comb. There is a large range of body size from a few millimetres, for Homalodromia coppingeri, to around 200 mm CW, for Dromia dormia. Egg size ranges from 0.4 mm to 1.1 mm diameter but there is no evidence of direct development amongst these dromiids. The apparent biogeographic affinities of the dromiids from New Caledonia and the Philippines are, in decreasing order, with Japan, Indian Ocean, Indonesia, and Australia. The apparent affinity with Japan may well be an artifact of more intensive collecting. The most wide ranging species are Lauridromia intermedia (Laurie, 1906), Dromia dormia (Linnaeus, 1763), D. wilsoni (Fulton & Grant, 1902) nov. comb., Cryptodromiopsis unidentata (Riippell, 1830) nov. comb., Cryptodromia hilgendorfi De Man, 1888, and C. fallax (Lamarck, 1818) nov. comb. These species also represent the most wide ranging genera. The collection of species largely consists of widely distributed species typical of an island fauna.

Résumé [+] [-]This is part of a series of papers (TAVARES, 1991a, 1991b, 1992a, 1992b, 1992c) reviewing the Cyclodorippidae Ortmann, 1892, and Cymonomidae Bouvier, 1897, of the world. It contains a review of all the Cyclodorippidae from the Indo West Pacific as well as one genus of Cymonomidae. This is a systematic approach preceding a more detailed study of the Cyclodorippoidea morphology and of the phylogenetic relationships within the superfamily. The present work was based upon large collections from the Indo-West Pacific (Madagascar, Japan, Vietnam, Philippines, Indonesia, Australia, Chesterfield Islands, New Caledonia, Loyalty Islands, and Wallis and Futuna Islands) carried out by the following French expéditions : MUSORSTOM 1-7, BIOCAL, CHALCAL 2, CORAIL 2, KARUBAR, LAGON, and SMIB 6. Also included is the material collected by the "Siboga" Expédition, 1899, CRUSTACEA DECAPODA : CYCLODORIPPIDAE ET CYMONOMIDAE 255 "Albatross", 1908, the material collected by the Russian océanographie ships "Orlik" in 1960 on the coast of Vietnam and "Vytiatz" on the west coast of Australia, two samples made by Raoul SERÈNE in Indonesia in during the RUMPHIUS I expédition in 1973 and RUMPHIUS IV in 1975, as well as collections made by the Australian ship "Soela" in 1984 on the north coast of Australia, and others made during the expédition CiDARis I under the auspices of the James Cook University on the Great Barrier Reef. Additional material from the collections of The Natural History Muséum (British Muséum), London ; Museum of Comparative Zoology, Massachusetts ; Zoological Museum of Moscow University ; National Science Museum, Tokyo; Northern Territory Muséum of Arts and Science, Darwin ; Queensland Museum, Brisbane ; South African Museum, Cape Town ; National Museum of Natural History, Smithsonian Institution, Washington and Zoologisch Museum, Amsterdam was also examined. Because of insufficient original descriptions, the re-examination of all type specimens [except for Tymolus truncatus (Ihle, 1916) which is apparently lost and Genkaia gordonae Miyaké and Takeda, 1970] and most of the spécimens cited in the literature, was required to properly establish the correspondence between species and the names introduced in the literature.Until now, seven gênera (Tymolus, Corycodus, Xeinostoma, Genkaia, Krangalangia, Ketamia, and Cymonomus) and23 species of Cyclodorippidae and Cymonomidae were known from the Indo-west Pacific. They are as follows : Cyclodorippidae : Tymolus japonicus Stimpson, 1858, T. uncifer (Ortmann, 1892), T. dromioides (Ortmann, 1892), T. similis (Grant, 1905), T. truncatus (Ihle, 1916), T. brucei Tavares, 1991, Corycodus disjunctipes (Stebbing, 1910), Xeinostoma eucheir Stebbing, 1920, Krangalangia rostrata (Ihle, 1916), K. spinosa (Zarenkov, 1970), Ketamia depressa (Ihle, 1916), Genkaia gordonae Miyaké and Takeda, 1970. Cymonomidae : Cymonomus valdiviae Lankaster, 1903, C. andamanicus Alcock, 1905, C. indicus Ihle, 1916, C. trifurcus Stebbing, 1920, C. japonicus Balss, 1922, C. curvirostris Sakai, 1965, C. aequilonius Dell, 1971, C. bathamae Dell, 1971, C. delli Griffin and Brown, 1976, C. umitake Takeda, 1981, C. hakuhoae Takeda and Moosa, 1990. From this study : — Two new genera (Phyllotymolinum and Elassopodus) and 11 new species of Cyclodorippoidea are herein described : Cyclodorippidae : Corycodus merweae, C. decorus, Xeinostoma richeri, X. sakaii, Krangalangia orstom, Ketamia handokoi, K. limatula, K. proxima, Genkaia keijii, Phyllotymolinum crosnieri. Cymonomidae : Elassopodus stellatus. — Two species are resurrected : Corycodus bouvieri Ihle, 1916, from the synonymy of C. disjunctipes (Stebbing, 1910) and Krangalangia spinosa (Zarenkov, 1970) from the synonymy of A", rostrata (Ihle, 1916).— Four lectotypes are designated here for the following species : Corycodus disjunctipes, Xeinostomaeucheir,Krangalangia rostrata, and Ketamia depressa.Presently, a total of 9 genera (7 Cyclodorippidae and 2 Cymonomidae) and 34 species (22 Cyclodorippidae and12 Cymonomidae) are known from the Indo-West Pacific. All these species are studied here except those belonging to the genus Cymonomus which will be treated in a future publication. Keys for families, genera and species are provided as well as illustrations for all species.

Résumé [+] [-]A large collection of species of the genus Munida has been examined and found to contain 56 undescribed species. The specimens examined were caught mainly off New Caledonia, Chesterfield Islands, Loyalty Islands, Matthew and Hunter Islands. Several samples from Kiribati, the Philippines and Indonesia have also been included. The specimens were collected between 6 and 2 049 m. Some species previously known in the area (Af. Gracilis, M. haswelli, M. microps, M. spinicordata and M. tubercidata) have been illustrated. These results point up the high diversity of this genus in the region and the importance of several characters in species identification (e.g., size and number of lateral spines on the carapace, ornamentation of the thoracic sternites, size of antennular and antennal spines, colour pattern).
Vidal, Jacques, 1994, A review of the genus Fulvia Gray, 1853 (Mollusca, Cardiidae), Apex, 9, 4, 93-118
Résumé [+] [-]The Cardiid genus Fulvia is revised based on examination of type material and over 900 lots in relevant muséums. Characters of shell sculpture are regarded as taxonomically more reliable than shape and colour, hitherto the base of spécifie taxonomy in the genus. It is established that Fulvia shares vvith l’epncardium numerous characters, including the présence of ocular organs on siphonal tentacles, and is included hère in the tribe VEPRICARDIINI. Laevifulvia subgen nov. (Type species: F. undatopicta Pilsbry, 1904) is segregated from Fulvia s.s., based on the lack of periostracal insertions on the ribs. Sixteen Indo-Pacific species of récent Fulvia are recognized, of which six are new. The name F. papyracea, hitherto used for a conimon Indo-West Pacific species is shown to represent a rare and restricted species. The name F. fragilis (Forsskal in Niebuhr, 1775) is to be used for most usages of F. papyracea of authors.

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

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 [+] [-]New Caledonian representatives of the muricid subfamily Trophoninae are revised. Two new genera are described and a total of 32 species are recorded, of which 24 are new to science. One species is refered to Apixystus Iredale, 1929, four to Trophonopsis Bucquoy & Dautzenberg, 1882, twenty-two to Leptotrophon n. gen., four to Conchatalos n. gen., and one to Litozamia Iredale, 1929. Two species formerly described in Poirieria (Paziella) (Muricinae) are transfered to Trophoninae. Three species are also known from SE and E Australia, and/or from Indonesia. The others are known only from the New Caledonian region. Most species live between 250 and 775 meters; only one species occurs in 105-110 m and three range deeper than 1000 m.

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

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

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

Résumé [+] [-]The New Caledonian species of Cones with a main distribution below 100 m are surveyed. This fauna consists of 39 species, of which 5 are new and 18 represent significant range extensions. In addition, eight species, mostly represented by single specimens, remain unidentified. Ten species (Conus boucheti, C. kanakinus, C. luciae, C. plinthis, C. richeri, and the five new ones) are so far only known from the New Caledonia region and may be endemic. Conus smirna and C. profundorum are regarded as distinct, and two additional species are described in this species complex: C. vaubani sp. Nov., from South of New Caledonia and of the New Hebrides Arc in 440-775 m; and C. loyahiensis sp. Nov. From the Loyalty Islands in 480-575 m. Three other new species, and one subspecies, are named: Conus alisi sp. Nov. From the New Caledonia area, in 200-525 m; C. estivali sp. Nov. From the Chesterfield Islands, Coral Sea, in 355-410 m; C. gondwanensis sp. Nov. From the Norfolk Ridge, South New Caledonia, in 170-260 m; and C. orbignyi coriolisi ssp. Nov., from the Coral Sea, New Caledonia and Loyalty Islands, in 225-550 m.

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

Résumé [+] [-]A collection of 52 species of palaemonoid shrimps from the Muséum national d'Histoire naturelle, Paris, is reported upon. Material is derived principally from the New Caledonian region but also includes specimens from Aden/Yemen, Comoro Islands, western Indian Ocean, Philippines, Indonesia and Wallis Island. Specimens have been collected from intertidal depths to over 600 m. Ten species have been collected from water depths of over 100 m. Two new genera of pontoniine shrimp are designated : Climeniperaeus, for Periclimenaeus truncoideus Chace & Bruce, 1993, and Typtonychus, for a new species, T. crassimanus. The following species are transferred from the genus Typton to the new genus Typtonychus : T. anomalus (Bruce, 1979), T. dentatus (Fujino & Miyake, 1969), and T. dimorphus (Bruce, 1986). These species are probably all associates of Porifera. Six new species of pontoniine shrimp are described. These include Conchodytes philippinensis, from an unknown locality in the Philippines; Mesopontonia verrucimanus, from 184-186 m in the Tanimbar Islands, Indonesia; Periclimenaeus colodactylus, from 20-25 m in New Caledonia, in association with Diplosoma versicolor Monniot; Periclimenes involens, from 92-97 m, off Mindoro, Philippines, of unknown association; Pontonia compacta, from 10- 60 m, in New Caledonia, in association with Pyura albaneyensis Michaelson and Pontonia simplicipes, from 71 m, in the Chesterfield Islands, in association with Pyura nigricans Heller.
Chan, Tin-Yam, Crosnier, Alain, 1996, Crustacea Decapoda Crangonidae : revision of the three closely related genera Aegaeon Agassiz 1846, Pontocaris Bate, 1888 and Parapontocaris Alcock 1901, Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 15, 168, 269-336
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 [+] [-]Six species of the two related bothid genera Tosarhombus and Parabothus from the Coral Sea are described and keys to species are provided: T. neocaledonicus Amaoka & Rivaton, 1991, T. longimanus sp. nov., T. brevis sp. nov., P. filipes sp. nov., P. kiensis (Tanaka, 1918) and P. coarctatus (Gilbert, 1905). T. longimanus is characterized by having uniserial teeth on upper jaw, a pectoral fin on the ocular side longer than the head in males, 6 2 - 7 1 scales in the lateral line and a light brownbody. T. brevis is characterized by having a deeper body, a shorter pectoral fin on the ocular side in males and smaller mouth. P.filipes is distinguished from known congeners of the genus by the greatly elongated pelvic fm in males and the small number of scales in the lateral line. P. kiensis and P. coarctatus represent first records from the Coral Sea.

Résumé [+] [-]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.

A monograph of the New Caledonian fauna and revisions of related taxa - Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, Edition du Muséum national d'Histoire naturelle, 19, 178
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 [+] [-]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.
McLay, Colin L., Crosnier, Alain, 1999, Crustacea Decapoda: Revision of the Family Dynomenidae, Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 20, 180, 427-569
Résumé [+] [-]The Dynomenidae are a group of small, uncommon, primitive crabs, which are often associated with corals. They inhabit depths down to around 500 m, between latitudes 40°N and 40°S. All genera and species are revised and redescribed, and the genus Dynomene Desmarest, 1823 is divided into two additional genera. As a result, there are thirteen known species belonging to five genera: Dynomene Desmarest, 1823 [D. hispida Guérin-Méneville, 1832, D. praedator A. Milne Edwards, 1879, D. pugnatrix de Man, 1889, D. filholi Bouvier, 1894, and D. pilumnoides Alcock, 1900], Hirsutodynomene gen. nov. [H. spinosa (Rathbun, 1911), and H. ursula (Stimpson, li>60)], Metadynomene gen. nov. [Ai. devaneyi (Takeda, 1977), M. tanensis (Yokoya, 1933), and M. crosnieri sp. nov.], Acanlliodromia A. Milne Edwards, 1880 [A. erinacea A. Milne Edwards, 1880, and A. margarita (Alcock, 1899)], and Paradynomene Sakai, 1963 [P. tuberculata Sakai, 1963]. A key is provided to identify these species. In addition nine fossil genera, dating from the Upper Jurassic, are known: Stephanonietopon Bosquet, 1854, Dromiopsis Reuss, 1859, Palaeodromites A. Milne Edwards, 1865, Cyamocarcinus Bittner, 1883, Graptocarcinus Roemer, 1887, Cyclothyreus Remes, 1895, Gemmellarocarcinus Checchia-Rispoli, 1905, Glyptodynomene Van Straelen, 1944, Trachynotocarcinus Wright & Collins, 1972. Some extinct species have also been placed in the genus Dynomene. The definition of the family Dynomenidae given by ALCOCK (1901) is updated and expanded in order to allow fossil species to be more accurately determined. Because of overlap with the Dromiidae, there has been some uncertainty about true family affinities of some fossils. Although these genera are in need of revision, this is not undertaken in this paper. The status oi Dynomene pilumnoides is established as a valid species, D. pugnatrix brevimana Rathbun. 1911 is synonymized with D. pugnatrix de Man, 1889, D. granulobata Dai, Yang & Lan, 1981 is a synonym of D. hispida, while D. sinensis Chen, 1979, D. tenuilobata Dai, Yang & Lan, 1981, and D. huangluensis Dai, Cai & Yang, 1996 are all synonyms of D. praedator. Dynomenids are reported from Australia for the first time in D. pilumnoides, and Hirsutodynomene spinosa. The status of Metadynomene tanensis (Yokoya, 1933) is established as a widespread Pacific species and shown to be part of the fauna of Japan, where it has been confused with D. praedator. Paradynomene tuberculata, previously known from Japan and New Caledonia, is now recorded from the Gulf of Aden, Indian Ocean. P. tuberculata as well as D. praedator and H. spinosa, are reported from Guam. The Atlantic Ocean and the Indo-Pacific share genera of dynomenids but not species. The biogeographic history of dynomenids is interpreted in the liglit of tfieir present distribution and in relation to plate tectonics. Ancestral dynomenids are assumed to have been tethyan crabs and D. filholi and Acanthodromia erinacea, two insular Atlantic species, are shown to be tethyan relicts. By contrast, Hirsutodynomene ursula from the eastem Pacific, seems to be a species of quite recent origin. In redescribing the species particular attention is paid to some new characters: setae, gills, epipods and gill cleaning mechanisms, the subchelate structure of the last pereopods and the male pleopods. This work was undertaken using a scanning electron microscope. Differences in the gross appearance of setae can be used to separate species and there are substantial differences in setal structure at the microscopic level. The standard branchial formula for dynomenids is shown to be nineteen gills plus seven epipods. There is little variation in gill numbers but substantial variation in gill shape between species. Although dynomenid gills are often said to be "transitional" they are arranged as in phyllobranchs but with the epibranchial part divided into varying numbers of lobes which gives them a trichobranch-like appearance. Acanthodromia has gills which are almost identical to the phyllobranchs of the Dromiidae but which retain the "dynomenid notch" on each side which, in cross section, give each gill plate a violin shape. The gill cleaning mechanism in dynomenids is complex, being carried out by no less than eight appendages (long setae on the posterior margin of the scaphognatbite and the seven epipods) as well as stiff setae on the posterior hypobranchial wall of the gill chamber. In eubrachyurans only three appendages (maxillipodal epipods) are used. In dynomenids the last pereopod is very reduced (on average less than one-third the length of the fourth pereopod) and carried in a horizontal position alongside the posterolateral carapace margin above the base of the preceding pereopod. They are not, as it has been commonly described, carried subdorsally. Using a scanning electron microscope it was revealed that this limb is sexually dimorphic: in males the dactyl has the normal shape of a tiny claw, but in females the dactyl is a flattened plate, bearing five to sixteen spines which are opposable to an extension of the propodus. In both males and females the propodal extension is armed with spines but in Hirsutodynomene. Metadynomene and Paradynotnene, females have a significantly larger number of spines, which are armed with tiny teeth. Males of three species have an additional small spine on the outer margin of the dactyl. This is a character, previously only known amongst the Dromiidae, which suggests that the last pereopod of dynomenids may have evolved from a camouflagecarrying limb. This limb appears to be vestigial and it is difficult to know what its function may have been amongst the dynomenid ancestors. However its most likely former role appears to be as a cleaning appendage, but certainly not for carrying pieces of camouflage as it is found amongst the dromiids and homolids. All dynomenids, except Acanthodromia, lack an effective abdominal locking mechanism and both sexes have five pairs of pleopods. The female has vestigial, uniramous first pleopods followed by four pairs of normal biramous pleopods, while the male has the normal first two pairs of pleopods as well as three pairs of rudimentary pleopods on segments three to five. These rudimentary pleopods can be uniramous or bifid. In Metadynomene tatiensis 17% of females were gynandromorphs with small male first pleopods but the remaining pleopods were normal. The diet of dynomenids seems to consist of food obtained by sieving fine sediment or perhaps coral mucus. The bunches of sfiff setae on the inner margins of the cheliped fingers and third maxillipeds are probably used to separate fine organic fragments. Most of their gut contents are unidentifiable soft organic material along with small amounts of chopped chitinous fragments perhaps coming from hydroids or other crustaceans. Dynomenids appear to be deposit feeders. Dynomenids have a broadcast reproductive strategy, with indirect development, laying small eggs (mean diameter = 0.49 mm) which probably produce planktonic larvae. Dynomenid larvae have never been reported in plankton samples. Males are on average 19% larger than females which become sexually mature at 5-8 mm CW for small species, or 9-13 mm CW for large species. Egg numbers increase logarithmically with body size. Given the sister group relationship with homolodromiids (which have very abbreviated development) it is implied that dynomenids and dromiids evolved from ancestors which had large eggs and perhaps a brooding strategy. This conclusion is contrary to accepted wisdom, but it is the most parsimonious answer. Some dromiids have retained the brooding strategy but others have independently evolved a broadcast strategy. The evolution of such a strategy in both these families is probably related to their colonization of the shallow water habitat. Both dynomenids and dromiids are mostly crabs of the continental shelf whereas homolodromiids are crabs of the continental slope. Using morphological characters the phylogenetic relafionships of the Dynomenidae are examined. Both the Dynomenidae and the Dromiidae are monophylefic, sharing significant apomorphies. The resemblance of some dynomenids and dromiids is shown to be the result of convergent evolution within these families. The Homolodromiidae are also monophyletic but are defined almost exclusively by plesiomorphies. Monophyly of the Dromiacea de Haan, 1833 is supported by morphological characters with the Dynomenidae and Dromiidae together being the sister group of the Homolodromiidae. The ancestor of these three families was probably a camouflage carrying crab, using both of the last two pairs of pereopods. A controversial aspect of the sister group relationships of the dromiaceans is the need to assume that in dynomenids the fourth pereopod has reverted to a locomotory role and the fifth pereopod became a cleaning limb. Monophyly of the Podotremata Guinot, 1977 is also supported. This analysis suggests that camouflage-carrying behaviour has evolved independently in the Dromiidae (and probably in the Homolodromiidae) and the Homolidae. Dromiids carry pieces of sponges or ascidians as well as shells, using the last two pairs of pereopods, while homolids carry sponges or anemones, using only the last pair of pereopods. The ancestor of the Dromiacea and Archaeobrachyura was probably an inhabitant of deeper waters and not a camouflage carrying crab.

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

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

Dolin, Luc, Bouchet, Philippe, Marshall, Bruce A., 2001, Les Triviidae (Mollusca : Caenogastropoda) de l’Indo-Pacifique : Révision des genres Trivia, Dolichupis et Trivellona, Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 22, 185, 201-241
Résumé [+] [-]The Indo-Pacific species of Trivia, Dolichupis and Trivellona are revised, based on the most abundant and comprehensive material ever brought together and reveals a previously unsuspected diversity of Triviinae in the upper bathyal zone (200-500 m) of the tropical West Pacific. The description of this fauna gives an opportunity to reevaluate the validity of numerous species- and genus-group taxa recognized earlier, both in the littoral and deep water zones. The present paper deals with Trivia Broderip, 1837, Decoriatrivia Cate, 1979, Dolichupis Iredale, 1930, and Trivellona Iredale, 1931. A forthcoming study will deal with Trivirostra Jousseaume, 1884, Cleotrivia Iredale, 1930, and Semitrivia Cossmann, 1903. By First Reviser action, Ellatrivia Iredale, 1931 is given precedence over Fossatrivia Iredale, 193 I . Decoriatrivia is treated as a subgenus of Trivia; Dolichupis is regarded as generically distinct from Pusula; the nominal genus Pseudotrivia is synonymized with Trivellona. Trivia (T.) cylindrica sp. novo from the Philippines, and Trivia (T.) vitrosphaera sp. nov., from New Caledonia, represent the first records of Trivia (T.) in the Indo-Pacific. Their deep-water occurrence contrasts with that of the six or so species from the littoral of the temperate and tropical eastern Atlantic. Dolichupis malvabasis sp. nov., a deep water species from the Philippines, is closely related to the type species and sole other representative of Dolichupis, D. producta (Gaskoin, 1836). Nine named and six new species are recognized in Trivellona: T. bulla sp. nov., T. conjonctiva sp. nov., T. oligopleura sp. nov., T. syzygia sp. novo and T. galea sp. nov., all from New Caledonia, and T. eglantina sp. novo from the Philippines. Trivia valerieae Hart, 1996 [= Erato tetatua Hart, 1996, syn. Nov.; First Reviser] is treated as a SW Pacific subspecies of T. paucicostata (Schepman, 1909); T. Shimajiriiensis McNeil, 1961, described from the Pliocene of Okinawa, is now recorded in the Recent fauna of the Philippines. Pusula niasensis Wissema, 1948 is a new synonym of Dolichupis producta (Gaskoin, 1836), Pseudotrivia sagamiensis KUI'oda & Habe, 1971 is a new synonym of T. sibogae (Schepman, 1909), and Fossatrivia suduirauti Lorenz, 1996 is a new synonym of T. speciosa (Kuroda & Cate, 1979). Three nominal species described by Cate (1979) supposedly from the Philippines are shown to be wrongly localized and synonyms of Atlantic taxa: Pseudotrivia samarensis is synonymized with Trivia (T.) arctica (Pulteney, 1799) from Europe, and Pseudotrivia dumaliensis and Niveria (Cleotrivia) aquatanica are both synonymized with Niveria (N) nix Schilder, 1922 from the Caribbean. Decoriatrivia halians Cate, 1979 and D. but'ius Cate, 1979 are both synonymized with Trivia (Decoriatrivia) pauci!irata Sowerby, 1870 from the Panamic Province.

Résumé [+] [-]A study of major collections led to a revision of the Indo-Pacific leucosioid genus Myra Leach, 1817. The systematic status and nomenclatural disposition of each species was assessed, and many were diagnosed based on examination of the type material. A new genus, Myrine, is established for M. acutidens (Ihle, 1918) and M. kesslerii (Paulson, 1875). The genus Myrodes Bell, 1855, is synonymized with Myra. Nine species are retained as valid: M. affinis Bell, 1855, M. australis Haswell, 1880, M. brevimana Alcock, 1896, M. elegans Bell, 1855, M. eudactyla (Bell, 1855), M. fugax (Fabricius, 1798), M. grandis Zarenkov, 1990, M. mammillaris Bell, 1855, and M. subgranulata Kossmann, 1877. Five new species are established: M. celeris, M. currax, M. curtimana, M. pernix and M. tumidospina. All species are described and illustrated, extended synonymies are given, and a key for their identification is provided.

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

Résumé [+] [-]Thirty-two species of Spondylus (Spondylidae) including eight previously undescribed, are recorded from material collected off New Caledonia and adjacent waters. Most of the species live in shallow water in coral reef and lagoonal environments, but at least four species have their main distribution at depths around 200 m, with one species occurring at 700 m. Spondylus exiguus sp. novo is the smallest known species in the family, with a maximum size of 6.4 mm. Spondylus flabellum Reeve, 1856 is placed into the synonymy of S. anacanthus Mawe, 1823. Confusion surrounding usage of the names Spondylus anacanthus and S. sanguineus Dunker, 1852 is finally resolved. The name Spondylus anacanthus, which has previously been applied to S. occidens Sowerby, 1903, is shown to be a prior and validly proposed name for S. sanguineus. Despite being well figured by MAWE, the absence of any documented type material for Spondylus anacanthus necessitates the establishment of a neotype for this species. Lectotypes are designated for Spondylus albibarbatus, S. butleri, S. castus, S. flabellum, S. ocellatus, S. pacificus, S. plurispinosus, and S. rubicundus, all of Reeve, 1856. By First Reviser action, the name Spondylus nicobaricus Schreibers, 1793 is given precedence over S. pseudochama Schreibers, 1793.
Holthuis, Lipke Bydeley, 2002, The Indo-Pacific scyllarine lobsters (Crustacea, Decapoda, Scyllaridae), Zoosystema, 24, 3, 499-683
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.
Randall, John E., Nagareda, Bronson H., 2002, Cirrhilabrus bathyphilus, a new deep-dwelling labrid fish from the coral sea, Cybium, 26, 2, 123-127
Résumé [+] [-]The labrid fish Cirrhifabrus bathyphifus is described as new from seven specimens collected in the Coral Sea, the holotype from Holmes Reef in the western part of the sea, a paratype from the aquarium trade, and 5 paratypes from 60-217 m from the Chesterfield Bank. This species is distinct in having 15 pectoral rays, 16-17 + 5 lateral-line scales, 5 median predorsal scales, 2 rows of sc ales on cheek, 14-15 gill rakers, a large eye (8.2-12.1% SL over the range in SL of 35-76 mm), emarginate caudal tin and short pelvic fins in the male, and a color pattern of the male of a very broad longitudinal black band in the outer part of the dorsal fin (absent in middle of fin of largest males), and a submarginal black band in the caudal tin.

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.

doi: 10.1016/j.crpv.2003.09.018 Résumé [+] [-]The primary cords of 68 species belonging to the Muricopsis/Murexsul lineages (Priabonian to Recent) are analysed. The study of their development allows distinguishing three derived sculptural patterns in Muricopsis and three in the Murexsul group. They appear late in the evolutionary history of the studied lineages, mainly in tropical waters. They are produced by heterochronies affecting precise cords by paedomorphosis, whereas others poorly evolved or may be hypermorphic. These results suggest that the phase of sculptural increase yielding the primitive pattern is followed by a selective phase, preserving or increasing the relief of the probable most functional cords.

Résumé [+] [-]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.

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 [+] [-]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 [+] [-]The Indo-West Pacific dynomenid genus Paradynomene Sakai, 1963, previously regarded as monotypic, is revised and six species are now recognized, viz. P. tuberculata Sakai, 1963, P. quasimodo n. sp., P. demon n. sp., P. diablo n. sp., P. teufel n. sp. and P. rotunda n. sp.. Most of the species are from deep to relatively deep waters with only one species (P. rotunda) known from shallow water. The species are distinguished by a combination of carapace features, notably carapace shape and height, form of the areolae, and position of major tubercles.

Five species of the samarid genera Plagiopsetta and Samaris (Samaridae), Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 23, 191, 611-635
Résumé [+] [-]Five species of the samarid genera Plagiopsetta and Samaris: P. stigmosa n. sp., P. gracilis n. sp., S. cristatus Gray, 1831, S. spinea n. sp. and S. chesterfieldensis n. sp., collected from New Caledonia and adjacent waters are described and keys to the species provided. Plagiopsetta stigmosa is easily separable from its congeners by having lateral lines on both sides and the pectoral fin with a jet-black blotch. Plagiopsetta gracilis is characterized by a uniformly dark pectoral fin, shallow body and caudal peduncle, a short ocular side pelvic fin, and large numbers of dorsal fin rays, anal fin rays, scales in the lateral line and vertebrae. Samaris spinea and S. chesterfieldensis are both characterized by caudal peduncle spines and bifurcated middle caudal fin rays, and are also separable by body depth.

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.
McLaughlin, Patsy A., Richer de Forges, Bertrand, Justine, Jean-Lou, 2006, Two new Paguridae (Crustacea, Decapoda) from New Caledonia and environs, Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 24, 193, 335-347
Résumé [+] [-]A new species in each of two recently proposed genera are described and illustrated: Alainopaguroides megalophthalmus n. sp., Icelopagurus undulatus n. sp. The new species assignable to Alainopaguroides McLaughlin expands the range of this genus from the Kai and Tanimbar Islands of Indonesia and the Andaman Sea to New Caledonia. Similarly, the discovery of a new and readily recognizable species belonging to the heretofore monotypic Icelopagurus McLaughlin extends the distribution of this genus from Indonesia to New Caledonia. The diagnoses of both genera have been emended slightly to accommodate the interspecific variation exhibited by the taxa now included.
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).
Snyder, Martin Avery, Hadorn, Roland, 2006, A new bathyal Fusinus (Mollusca: Gastropoda: Fasciolariidae) from New Caledonia, Zootaxa, 1311, 1-12
Résumé [+] [-]A new bathyal species of Fusinus is described from New Caledonia. Fusinus laviniae new species is distinguished from other New Caledonia Fusinus by its long siphonal canal and angular sculpture. This new species is compared to F. colus (Linnaeus, 1758), F. nicobaricus (Roding, 1798), F. nobilis ( Reeve, 1847), F. salisburyi Fulton, 1930, F. similis (Baird, 1873), and F. undatus, (Gmelin, 1791). A range extension for F. nobilis to New Caledonia is noted.
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 [+] [-]The greatest part of the types of the brachyuran crabs (Crustacea, Decapoda) in the Crustacea collection of the Museum national d'Histoire naturelle, Paris, is already catalogued on registers and is to be gradually published. This first annotated catalogue lists the nominal species belonging to the Podotremata (i.e. crabs with coxal male and female gonopores, and spermathecae): families Homolodromiidae, Dromiidae, Dynomenidae, Homoliclae, Poupiniidae, Cycloclorippidae, Cymonomidae, Phyllotymolinidae and Raninidae. The names of the taxa are presented in their original combination. The erroneous references to specimens as "types" have been noted and corrected in conformity with the International Code of Zoological Nomenclature. The types of a total of 104 species are listed herein, out of about 370 known species of podotreme crabs. Photographs of most of the type specimens are also provided. A bibliography and an index are included.

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.
Glover, Emily A., Taylor, John D., 2007, Diversity of chemosymbiotic bivalves on coral reefs: Lucinidae (Mollusca, Bivalvia) of New Caledonia and Lifou, Zoosystema, 29, 1, 109-181
Résumé [+] [-]Thirty-four species of marine bivalve molluscs of the family Lucinidae are described and illustrated from water depths less than 200 m around New Caledonia, the Loyalty Islands and Chesterfield Bank. Most of the bivalves came from three intensively sampled sites: Koumac and Touho on New Caledonia and Lifou in the Loyalty Islands. Eighteen new species are described. Nine new genera (Myrtina n. gen., Poumea n. gen., Solelucina n. gen., Discolucina n. gen., Lepidolucina n. gen., Ferrocina n. gen., Liralucina n. gen., Parvidontia n. gen. And Bretskya n. gen.) include both new and previously described species. Additionally, new descriptions and illustrations of type species are provided for two previously misunderstood genera – Epicodakia Iredale, 1930 and Gonimyrtea Marwick, 1929. The fauna described in this study is the most diverse assemblage of chemosymbiotic bivalves yet recorded.
Iwatsuki, Yukio, Akazaki, Masato, Taniguchi, Nobuhiko, 2007, Review of the species of the genus Dentex (Perciformes: Sparidae) in the western Pacific defined as the D. hypselosomus complex with the description of a new species, Dentex abei and a redescription of Evynnis tumifrons, Bull. Natl. Mus. Nat. Sci., Ser. A, Suppl, 1, 29–49
Résumé [+] [-]The lectotype of Chrysophrys tumifrons designated by Boeseman (1947) is a specimen of the species currently recognized as Evynnis japonica Tanaka, 1931. The name is, therefore, the senior synonym for that species. Dentex spariformis Ogilby, 1910, based on specimens collected at Moreton Island, Queensland, Australia, is redescribed and resurrected as a valid species, having previously been synonymized with D. tumifrons (Temminck and Schlegel, 1843). Dentex abei sp. Nov. Is described from ten type and 30 non-type specimens collected in the Ryukyu Islands, Chichi-jima of Ogasawara Islands (=Bonin Islands), Japan, and Luzon Island, Philippines. These two Dentex species, together with D. hypselosomus Bleeker, 1854 and D. fourmanoiri Akazaki and Séret, 1999 are recognized as a “Dentex hypselosomus complex” and reviewed on the basis of western Pacific and southern Indonesian material. Dentex hypselosomus differs from the others in having three eye-sized fluorescent yellow blotches dorsally, plus a small yellow spot posteriorly on the soft dorsal fin base (vs. Small bright cobalt or blue-spotted lines on the body in D. abei and no spots in D. fourmanoiri and D. spariformis) and deeper suborbital depth. Dentex fourmanoiri differs from D. spariformis in having 13 dorsal fin spines and 9 soft dorsal fin rays (vs. 12 spines and 10 rays). Dentex spariformis has a larger eye than D. abei and D. hypselosomus (mean orbit diameter 2.78 in head length vs. 3.66 and 3.32, respectively). Although none of the four species have been recorded in the equatorial zone, D. abei and D. hypselosomus are allopatric in the Northern Hemisphere, while D. spariformis and D. fourmanoiri are allopatric in the Southern Hemisphere, too. A key to the complex is provided.

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

Résumé [+] [-]Taxonomic and ecological interest in squat lobsters has grown considerably over the last two decades. A checklist of the 870 current valid species of squat lobsters of the world (families Chirostylidae, Galatheidae and Kiwaidae) is presented. The compilation includes the complete taxonomic synonymy and geographical distribution of each species plus type information (type locality, repository and registration number). The numbers of described species in the world's major ocean basins are summarised.

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

How far to go?, Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 25, 196, 9-40
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.
Valdés, Ángel, Héros, Virginie, Cowie, Robert H., Bouchet, Philippe, 2008, Deep-sea “cephalaspidean” heterobranchs (Gastropoda) from the tropical southwest Pacific, Tropical Deep Sea Benthos, 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.

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

Résumé [+] [-]Two new species of squat lobsters are described. Agononida rubrizonata n. sp. from Taiwan, Vanuatu, New Caledonia, Queensland and New South Wales, is distinguished from A. incerta (Henderson, 1888) by the male telson with a strong anterolateral process and different color pattern, although females of the two species are not morphologically separable. In order to establish the taxonomic status of A. incerta originally described from a female holotype, topotypic material is described. Paramunida leptotes n. sp. from the Izu Islands off Honshu, Japan, the Kyushu-Palau Ridge, off Amami-oshima of the Ryukyus, and Taiwan is distinguished from P. proxima (Henderson, 1885) by the absence instead of presence of a spine on the posterior ridge of the fourth abdominal somite and much narrower and more elongate third antennal segment that is at least 1.5 times longer than instead of as long as broad and about half instead of two-thirds as broad as the article 2.

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

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.

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.

Résumé [+] [-]A new species of parthenopid crab, Pseudolambrus guinotae n. sp., is described. The single male specimen, which was collected from New Caledonia, most closely resembles Pseudolambrus planus (Rathbun, 1911) but can be easily differentiated from the latter by possessing a much longer rostrum.

doi: 10.1111/j.1096-3642.2010.00681.x Résumé [+] [-]The genus Allogalathea was established by Baba in 1969 to include the well-known species Galathea elegans. This species is widely distributed across the Indo-West Pacific Ocean, and is characterized by living in close association with crinoids, and by its conspicuous coloration. Although the genus is considered monospecific, different colour patterns and discrete morphological variations mainly associated with the rostrum and chelipeds have been reported. These differences could point to cryptic species, thereby questioning Allogalathea as a monotypic taxon. To address this issue, we sequenced the mitochondrial cytochrome oxidase I (COI; 658 bp) and 16S rRNA (882 bp) genes and the nuclear gene phosphoenolpyruvate carboxykinase (PEPCK; 598 bp) in numerous specimens from eight different localities, and also examined their morphological characters. DNA sequences were analysed using maximum-parsimony, maximum-likelihood, and Bayesian approaches of phylogenetic inference. The resulting trees were combined with morphological evidence to test species boundaries. Our molecular data revealed four deeply divergent clades, which can be distinguished by subtle morphological differences in the spinulation and length: breadth ratio of the P1 carpus, spinulation of the walking legs, and shape of the rostrum. Our findings indicated that Allogalathea elegans is in fact a species complex comprising four different species, which, although genetically very distinct, are morphologically very similar. We provide morphological descriptions and a key to these four species of the genus.
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].

Résumé [+] [-]The taxonomy of the genus Turris Batsch, 1789, type genus of the family Turridae, widespread in shallow-water habitats of tropic Indo-Pacific, is revised. A total of 31 species of Turris, are here recognized as valid.

Résumé [+] [-]Careful examination of the morphology of recently obtained specimens as well as previously reported specimens of the genus Sadayoshia, initiated by unpublished molecular data that suggest the existence of several different species, led us to describe six new species. The species are very similar to one another and distinguished by very slight morphological differences. Some of the characters that were previously considered as intraspecifically variable in some species, proved to be valid for species discrimination. A dichotomous key to all species of the genus is provided.

Résumé [+] [-]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 [+] [-]The genus Nemocardium Meek, 1876, is traditionally considered a relict of the past. Morphometric and morphological analyses reveal that the well-known species N. bechei (Reeve, 1847) is in need of taxonomic reconsideration. In this paper, five species are recognized, three of which are new to science: N. bechei from Taiwan, Philippines and Indonesia; N. probatum (Iredale, 1927) from northern Australia; N. australojaponicum spec. nov. From southern Japan and Korea; N. enigmaticum spec. nov. From the SouthWest Pacific and N. fulvum spec. nov. from Mozambique, Madagascar, Seychelles, India, Philippines and Vanuatu. All but the last species seem to occur perfectly parapatrically. With N. fulvum spec. nov., which is not confined to the Central Indo-Pacific but covers large parts of the Indian Ocean as well, the longitudinal range of Nemocardium is much wider than hitherto thought. A substitute lectotype is designated for Cardium bechei Reeve, 1847, and the New Zealand genus Varicardium Marwick, 1944, is synonymized with Nemocardium.

doi: 10.5252/z2014n4a6 Résumé [+] [-]This publication is the third in a series of accounts on large collections of Plumularioidea McCrady, 1859 (Cnidaria, Hydrozoa, Hydroidolina) obtained during several French expeditions to the Philippines region, Vanuatu, New Caledonia, Fiji, and the Marquesas Islands. Additional material from Mozambique was also examined and is discussed. A total of 17 species, belonging to the families Kirchenpaueriidae Stechow, 1921 (two species) and Plumulariidae McCrady, 1859 (15 species), are scrutinized and illustrated in the present report. Three new species of the genus Plumularia Lamarck, 1816 are described (Plumularia bathyale n. sp., Plumularia contraria n. sp., Plumularia pseudocontraria n. sp.). The name Plumularia milsteinae n. nom., is proposed for Plumularia spiralis Milstein 1976, a permanently invalid junior homonym of Plumularia spiralis Billard, 1911. Polyplumaria kossowskae (Billard, 1911) is recorded for the first time since its original description. Two species of Plumularia are identified only to the genus level. Type materials of Plumularia habereri Stechow, 1909 and Dentitheca hertwigi Stechow, 1909, and the syntypes of all varieties of Plumularia habereri described by Billard (1913), have also been examined.

This study is based primarily on recent expedition material from the Institut de Recherche pour le Développement (New Caledonia) and Muséum National d’Histoire Naturelle (France). A total of 22 species is recorded, of which eight are described as new. New species: Clavus boucheti, Clavus delphineae, Clavus virginieae, Clavus picoides, Clavus squamiferus, Clavus devexistriatus, Clavus hylikos, Clavus maestratii; New synonyms: Tylotiella Habe, 1958 = Clavus; Clavus leforestieri Hervier, 1896 = Pleurotoma obliquicostata Reeve, 1845; Pleurotoma mariei Crosse, 1869 = Pleurotoma lamberti Montrouzier, 1860; Clavus mighelsi Kay, 1979, new name for Pleurotoma acuminata Mighels, 1845, non J. Sowerby, 1816, was misidentified by Kay 1979; the lectotype of P. acuminata Mighels, 1845, is mangeliine. Clavus mighelsi sensu Kay 1979, is a synonym of Pleurotoma humilis E. A. Smith, 1879. It is suggested that Pleurotoma pulchella Reeve, 1845, sometimes treated as an Indo-Pacific species, may be a senior synonym of Fenimorea halidorema Schwengel, 1940, from the tropical western Atlantic. Nomen dubium: Pleurotoma mediocris Deshayes, 1863.
Kool, Hugo H., Galindo, Lee Ann, 2014, Description and Molecular Characterization of Six New Species of Nassarius (Gastropoda, Nassariidae) from the Western Pacific Ocean, American Malacological Bulletin, 32, 2, 147-164
doi: 10.4003/006.032.0202 Résumé [+] [-]Six new species of the genus Nassarius Duméril, 1805 are described, based on material collected from the Coral Triangle and the South Pacific. We combine traditional morphology-based descriptions with the molecular (Cytochrome c oxidase I - COI) signature of the new species. New species are: Nassarius ocellatus sp. Nov. (Philippines to Vanuatu), Nassarius houbricki sp. Nov. (Solomon Islands to Queensland and Tonga), Nassarius radians sp. Nov. (Philippines to Vanuatu), Nassarius vanuatuensis sp. Nov. (Vanuatu), Nassarius velvetosus sp. Nov. (Western Australia to Fiji) and Nassarius martinezi sp. Nov. (Solomon Islands to Tonga).
Poore, Gary C. B., Andreakis, Nikos, 2014, More species of the Agononida incerta complex revealed by molecules and morphology (Crustacea: Decapoda: Anomura: Munididae), Zootaxa, 3860, 3, 201-225
doi: 10.11646/zootaxa.3860.3.1 Résumé [+] [-]Squat lobsters from Madagascar, Vanuatu, Papua New Guinea, Fiji, eastern Australia and French Polynesia belonging to the Agononida incerta (Henderson, 1888) species complex are described as four new species: A. madagascerta, A. polycerta, A. tasmancerta and A. vanuacerta. This brings to ten the number of species in this complex. All species are morphologically distinguishable only on the basis of the shape of the anterolateral margin of the telson and setation of the dactyli of pereopods 2–4. The morphological delineation of nine of the species and their taxonomic status are robustly supported by phylogenetic analysis of the partial 16S rDNA gene and the partial mitochondrial cytochrome oxidase subunit 1 genes, and in some cases by colour. A phylogenetic analysis of the nine species for which molecular data are available grouped the species in two clades, one of four species with facial spines on the upper surface of pereopod 4 and the other of five species lacking facial spines.
Voronina, Elena, Causse, Romain, 2014, New record of the bothid flounder Parabothus taiwanensis (Bothidae, Pleuronectiformes) from the southern Pacific Ocean (Vanuatu Archipelago) with description of a new diagnostic character, Cybium, 38, 2, 149–152
Résumé [+] [-]The bothid flounder family Bothidae contains 20 genus and 166 species. Most of the known species have wide distributions, others are restricted to specific zones and depth ranges. Fourteen bothid specimens captured near Vanuatu Archipelago were confirmed to be Parabothus taiwanensis (Pleuronectiformes; Bothidae), a rare species described before from only five specimens from the coasts of Taiwan and recorded only from the East China Sea (Amaoka and Shen, 1993; Yamada et al., 2007). The present note provides a description of these specimens with considerable range extension for this species and a new diagnostic character.

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.

Smith, 1906 (Gastropoda: Buccinidae) and related genera, with descriptions of 21 new species, Tropical Deep-Sea Benthos, Mémoires du Muséum national d’Histoire naturelle, 29, 208, 363-456
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.

doi: 10.3897/zookeys.758.25100 Résumé [+] [-]A new genus, Limatium gen. n., and two new species, L. pagodula sp. n. and L. aureum sp. n. are described, found on outer slopes of barrier reefs and fringing reefs in the South Pacific. They are rare for cerithiids, which typically occur in large populations. The two new species are represented by 108 specimens sampled over a period of 30 years, only 16 of which were collected alive. Three subadults from the Philippines and Vanuatu likely represent a third species. In addition to their rarity, Limatium species are atypical for cerithiids in their smooth, polished, honey to golden brown shells with distinctive white fascioles extending suture to suture. The radula presents a unique morphology that does not readily suggest an affinity to any of the cerithiid subfamilies. Two live-collected specimens, one of each species and designated as holotypes, were preserved in 95% ethanol and sequenced. Bayesian analysis of partial COI and 16S rDNA sequences demonstrates a placement in the Bittiinae, further extending our morphological concept of the subfamily.
