Kantor, Yuri I., Bouchet, Philippe, Oleinik, Anton, 2001, A revision of the Recent species of Exilia, formerly Benthovoluta (Gastropoda: Turbinellidae)., Ruthenica, 11, 2, 81-136
Résumé [+] [-]The range of shell characters (overall shape, sculpture, columellar plaits, protoconchs) exhibited by fossil and Recent species placed in Exilia Conrad, 1860, Mitraefusus Bellardi, 1873, Mesorhytis Meek, 1876, Surculina Dall, 1908, Phenacoptygma Dall, 1918, Palaeorhaphis Stewart, 1927, Zexilia Finlay, 1926, Graphidula Stephenson, 1941, Benthovoluta Kuroda et Habe, 1950, and Chathamidia Dell, 1956 and the anatomy of the Recent species precludes separation of more than one genus. Consequently all of these nominal genera are synonymised with Exilia, with a stratigraphical range from Late Cretaceous to Recent. Anatomically, Exilia is similar to other ptychatractine genera, but is characterized by a stomach with a long, narrow caecum, a penis with terminal fold surrounding the seminal papilla, and a radula with rachidian teeth with broad lateral flaps. Recent species of Exilia are restricted to deep water at middle to low latitudes in the Indian and Pacific oceans. Exilia hilgendorfi (Martens, 1897) is treated as a species highly variable within its broad IndoPacific distribution, with Benthovoluta gracilior Rehder, 1967, B. claydoni Harasewych, 1987, and B. prellei Bozzetti, 200 I considered local variants. Three new species are described: Exilia graphiduloides sp. nov. (New Caledonia, 520 m), E. vagrans sp. nov. (West and SW Pacific, 865-1280 m), and E. kiwi sp. nov. (New Zealand, 1386-1676 m).
Bouchet, Philippe, 2002, Protoconchs, dispersal and tectonic plates biogeography: new Pacific species of Morum (Gastropoda: Harpidae)., Journal of Conchology, 37, 5, 533-550
Résumé [+] [-]Morum clatratum n. sp. and Morum roseum n. sp. are described from depths of 100-200 m in the Marquesas Islands. Mode of development inferred from protoconch morphology and comparison with the protoconchs of Harpa with teleplanic larvae suggests that the new species have planktotrophic larval development, and that they are expected to range widely outside the Marquesas. In addition, Morum kurzi, M. macdonaldi, and M. teramachii, with inferred planktotrophic development, and M. watanabei, with inferred non-planktotrophic development, are newly recorded from South Pacific localities. The distribution of individual species of Morum appears to reflect dispersal during the planktonic phase, rather than movement of the lithospheric plates on the geological scale. The Caribbean Morum oniscus and M. lamarckii, respectively with inferred non-planktotrophic and planktotrophic development, are treated as separate valid species.
Crosnier, Alain, 2002, Révision du genre Parathranites Miers, 1886 (Crustacea, Brachyura, Portunidae), Zoosystema, 24, 4, 799-825
Résumé [+] [-]Based on rather abundant material from the Indo-West Pacific, the number of species in the genus Parathranites Miers, 1886 is elevated from two to eight. The six new species are P. granosus n. sp., P. tuberosus n. sp., P. tuberogranosus n. sp., P. ponens n. sp., P. intermedius n. sp. and P. parahexagonum n. sp. Examination of the type series of the type species for the genus, P. orientalis Miers, 1886, shows that it contains two species; a lectotype is designated for P. orientalis. The main morphological characters used for differentiating the species are the breadth/length ratio of the carapace (correlated with the length of the fifth anterolateral teeth of the carapace) which can vary from 1.3 to 2.1, the presence or absence of a median tubercle on the posterior part of the cardiac area, the granulation of the carapace and the shape of the first male pleopods. An identification key for members of this genus is proposed.

Crosnier A., 2003, Sicyonia (Crustacea, Decapoda, Penaeoidea, Sicyoniidae) de l’Indo-ouest Pacifique, Zoosystema, 25, 2, 197-348
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.
Fraussen, Koen, 2003, Three new deep-water species of Phos Montfort, 1810 (Gastropoda: Buccinidae) from the South Pacific, Novapex, 4, 4, 111-118
Résumé [+] [-]Phos alabastrum sp. nov. and P. boucheti sp. nov. are characterized by a striking bicarinate protoconch, a character they hâve in common with the Carribean species oï Antillophos Woodring, 1928. The colour of the protoconch and the absence of strong sculpture on the teleoconch distinguish both species from the Australian P. sciilptilis Watson, 1886. P. deforgesi sp. nov. differs from the preceding species and from some species of H inia (Nassariidae) in having a siphonal notch.

Hadorn, Roland, Fraussen, Koen, 2003, The deep-water Indo-Pacific radiation of Fusinus (Chryseofusus subgen. nov.) (Gastropoda: Fasciolariidae), Iberus, 21, 1, 207-240
Résumé [+] [-]A number of fusinids from the Indo-Pacific deep-water fauna are studied to get more insight in the distribution and variability. The subgenus Chryseofusus (Gastropoda: Fasciolariidae: Fusinus Rafinesque, 1815) is described as new to accommodate a number of species sharing conchological characteristics different from typical Fusinus. Their separation from Fusinus s.s. is based on differences in axial sculpture (usually absent on body whorl), spiral sculpture (weak, close-set, regular, crossed by distinct growth lines), shape (shorter spire, shorter siphonal canal, less convex whorls with subsutural concavity, less constricted suture) and parietal callus (inner lip smooth, parietal wall covered with an extended, adherent thin layer as callus). Fusinus (Chryseofusus) bradneri (Drivas and Jay, 1990), F. (C.) chrysodomoides (Schepman, 1911), F. (C.) graciliformis (Sowerby, 1880), F. (C.) hyphalus M. Smith, 1940, F. (C.) jurgeni Hadorn and Fraussen, 2002, F. (C.) kazdailisi Fraussen and Hadorn, 2000 and F. (C.) subangulatus (von Martens, 1901) are briefly described and their taxonomic placement in the new subgenus is discussed. To avoid further taxonomic complications, a lectotype is designated for the correct F. (C.) chrysodomoides. F. (C.) acherius (west Madagascar, Mozambique Channel, 1475-1530 m), F. (C.) alisae (north New Caledonia, 444-452 m), F. (C.) artutus (Philippines, Bohol, deep water), F. (C.) cadus (south New Caledonia, 460-470 m), F. (C.) dapsilis (Vietnam, deep water), F. (C.) riscus (New Caledonia, Norfolk Ridge, 394-401 m), F. (C.) scissus (south New Caledonia, 535 m), F. (C.) wareni ( New Caledonia, 480 m), and F. (C.) westralis (northwest Australia, off Port Hedland, 450 m) are described as new to science.
Monniot, Françoise, Monniot, Claude, 2003, Ascidies de la pente externe et bathyales de l’ouest Pacifique, Zoosystema, 25, 4, 681-749
Résumé [+] [-]The specimens collected during several recent oceanographic cruises in the tropical western Pacific, sponsored jointly by the MNHN and the IRD, consist of 53 ascidian species, and among them 16 new species. For others, the geographic distribution is increased in the western Pacific. The remarkably high diversity of these organisms between 50 and 1000 m in this part of the world is demonstrated. In all oceans at these depths the ascidian fauna is dominated by solitary organisms, whereas along the littoral fringe the majority of ascidian species are colonial. This systematic pattern is likely to be influenced by substrate: hard nearshore and soft offshore. In this study, among the new species, the solitary ascidians largely dominate, especially well represented by stolidobranchs with eight Styelidae of four genera, four Pyuridae with also four genera, and one Molgulidae. However the originality of this deep fauna is enhanced by the presence, in the typical Octacnemidae family, of a new genus Myopegma n. gen. with a very small species M. melanesium n. gen., n. sp. which has a very peculiar musculature justifying a new taxon.

P. van, Hartog, Koos den, Fautin, Daphne G., Den Hartog, J.C., 2003, An unusual sea anemone from slope depths of the tropical west Pacific: range extension and redescription of Isactinerus quadrilobatus Carlgren, 1918 (Cnidaria: Actinaria: Actinernidae), Koos den Hartog memorial volume, Zoologische verhandelingen, 345, 103-116
Résumé [+] [-]The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus fiavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral dise had four lobes (I quadrilobatus) or eight (Synactinernus Flavus) - we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number.

Résumé [+] [-]Pycnogonids material from the Muséum national d'Histoire naturelle, Paris, collected by French oceanographic campaigns to New Caledonia, Fiji and Tonga in 1993, 1999 and 2000, is described. Of the thirteen species recorded, a new species of Colossendeis is described from Fiji and two new ammotheid species are described from New Caledonia, one in each of the genera Cilunculus and Dromedopycnon. In addition, Cilunculus scaurus, Anoplodactylus typhloides and Pycnogonum (Nulloviger) moniliferum are recorded for only the second time; the opportunity is taken to revise the description of the latter in the light of damage to som of the type specimens.
Bouchet, Philippe, Kantor, Yuri I., 2004, New Caledonia: The major centre of biodiversity for volutomitrid molluscs (Mollusca: Neogastropoda: Volutomitridae), Systematics and Biodiversity, 1, 4, 467-502
doi: 10.1017/S1477200003001282 Résumé [+] [-]Recent deep-sea explorations in the South Pacific have documented around New Caledonia the most diverse fauna of gastropods of the family Volutomitridae anywhere in the world. Fourteen species (nine new, two remaining unnamed) are recorded, all essentially confined to the 250–750 m depth range. The high number of species in the New Caledonia region does not appear to be an effect of sampling intensity, but appears to result from four factors: regional spatial heterogeneity, frequency of hard substrates, syntopy, and a historical heritage shared with Australia and New Zealand, which until now ranked as the major centre of volutomitrid diversity. In the New Caledonia region, volutomitrids show a marked preference for hard bottoms and up to three species may cooccur in the same dredge haul. Many species appear to have extremely narrow geographical distributions within the region (e.g. a single seamount or a single submerged plateau); conversely, Microvoluta joloensis, the only non-endemic volutomitrid present in New Caledonia, ranges from the Mozambique Channel to Tonga.
Chan, Tin‐Yam, Marshall, Bruce A., Richer de Forges, Bertrand, 2004, The ‘‘Plesionika rostricrescentis (Bate, 1888)’’ and ‘‘P. lophotes Chace, 1985’’ species groups of Plesionika Bate, 1888, with descriptions of five new species (Crustacea: Decapoda: Pandalidae), Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 23, 191, 293-318
Résumé [+] [-]Before the present study, Plesionika rostricrescentis (Bate, 1888) and P. lophotes Chace, 1985 were the two Plesionika species unique in having a high basal rostral crest. A recently described species, P. erythrocyclus Chan & Crosnier, 1997 has a low basal rostral crest but is evidently related to P. rostricrescentis. Close examination of the abundant material collected during the MUSORSTOM expeditions and from Taiwan revealed that there are at least eight species in this ‘‘P. rostricrescentis-P. lophotes’’ species complex. These taxa are morphologically very similar but can be distinguished by their very distinctive colorations, which are often striking and consist of large circular spots. In the ‘‘P. rostricrescentis’’ group, which has the dorsal margin of the rostrum unarmed between the anteriormost tooth of the basal rostral crest and the subapical teeth, five species are recognized. Plesionika rostricrescentis is still known only by the holotype from the Kai Islands. Two new species, P. hsuehyui and P. suffusa, closely similar to P. rostricrescentis, are described. Plesionika hsuehyui is widely distributed from Taiwan to Fiji, while P. suffusa has only been found off New Caledonia. Plesionika erythrocyclus, previously known only from Taiwan and French Polynesia, occurs widely in the southern Pacific. Another new species, P. bimaculata, which closely resembles P. erythrocyclus, is distributed off New Caledonia and in adjacent areas. Three species are recognized in the ‘‘P. lophotes’’ group, which bear dorsal rostral teeth between the basal rostral crest and subapical teeth. Plesionika lophotes is restricted to the area between Japan and northwestern Australia. Two further closely similar new species, P. rufomaculata and P. scopifera are described, the former widely distributed from Okinawa to Futuna Island, the latter only off New Caledonia and Tonga. Although coloration is very important in distinguishing these species, species with similar color patterns do not necessarily belong to the same species group. Morphologically, these species are mainly separated by the height of the basal rostral crest, the number of rostral teeth, and the length of the stylocerite and the dactyli of the posterior three pereiopods. However, there is sexual dimorphism in the development of the basal rostral crest in these species, sometimes making positive identification of males and young specimens difficult.
Cleva, Régis, 2004, Stylodactylidae and Bathypalaemonellidae from Taiwan (Crustacea: Decapoda: Caridea), Raffles Bulletin of Zoology, 52, 2, 497–511
Résumé [+] [-]Seven shrimp species of the family Stylodactylidae are reported here from Taiwanese waters, four of which represent new records for the area. Only three species of this family were previously known from Taiwan: Stylodactylus in multidentatus Kubo, 1942, and Parastylodactylus bimaxillaris (Bate, 1888), both present in the collection studied here, and Bathystylodactylus inflatus Hanamura & Takeda, 1996, no material in the present collection. Stylodactylus major Hayashi & Miyake, 1968, is recorded for the second time. The other species are: Stylodactylus libratus Chace, 1983, Stylodactylus licinus Chace, 1983, and Stylodactylus tokarensis Zarenkov, 1968. On another hand, the status of a seventh species, related to Stylodactylus pubescens Burukovsky 1990, is left unresolved. The rare deep-sea shrimp family Bathypalaemonellidae is added to the Taiwanese decapod fauna, being represented by four species, one of which is new: Bathypalaemonella hayashii Komai, 1995; Bathypalaemonetes brevirostris (Bruce, 1986); Bathypalaemonetes pilosipes (Bruce, 1986) and Bathypalaemonetes chani, new species.

Résumé [+] [-]Hymenopenaeus obliquirostris ( Bate, 1881), a relatively poorly known species, is redescribed, figured and compared with H. halli Bruce, 1966. Two other species of Hymenopenaeus, H. methalli from the southwest Pacific and H. fallax from Hawaii, are described as new. All these species are closely related to one another. They are distinguished essentially by the presence or absence of a postrostral carina, the presence or absence of a fixed spine on the merus of the first pereopods, and the shape of parts of the thelycum and petasma.
Galil, Bella S., 2004, A new deep water leucosiid genus (Crustacea, Decapoda, Brachyura), Zoosystema, 26, 3, 495–502
Résumé [+] [-]A new genus, Ancylodactyla n. gen., is established for two deep water species excluded from Praebebalia Rathbun, 1911, P. elongata Zarenkov, 1969, and P. elata Zarenkov, 1994, and for Randallia nana Zarenkov, 1990, provisionally assigned to Randallia s.s. A study of the extensive collection of leucosiid crabs made by French expeditions to the Indo-Pacific Ocean has increased the known geographic and bathymetric ranges of these species. The new genus is distinguished from Praebebalia and from Randallia s.s. in having male abdominal somites 3-6 fused, and the second male pleopod longer than first pleopod. The species are redescribed, fully illustrated, synonymies are discussed, and a key for their identification is provided.

Résumé [+] [-]All described Indo-Pacific taxa referable to the epitoniid genus Cycloscala Dall, 1889 are listed and evaluated. The type species, Cycloscala echinaticosta (d'Orbugny, 1842) is discussed. Four described Inod-Pacific Cycloscala species, considered valid herewith, are treated: Cycloscala crenulata Pease, 1867; C. gazae Kilburn, 1985; C. hyalina Sowerby II, 1844; and C. revoluta Hedley, 1899. Three new species are described: Cycloscala armata, C. sardella, and C. montrouzieri.

Résumé [+] [-]The Pasiphaea cristata species group is treated herewith, as the second part of the revision of genus Pasiphaea Savigny, 1816. The group is primarily characterized by presence of a complete gill formula, unarmed posterior margin of the merus of the first pereopod, and unarmed posterior margin of the ischium and basis of the second pereopod. The group comprises twenty two species, four of which are new species from MUSORSTOM material. Pasiphaea nishiei Iwasaki proves to be a junior synonym of P. merriami Schmitt, and P. vereschhaka Burukovsky is probably a junior synonym of P. amplidens Bate. Pasiphaea australis Hanamura has the same pereopodal armatures as this group, but entirely lacks arthrobranchs and is referred to Alainopasiphaea Hayashi. The genus Pasiphaea is redefined by including Phye Wood-Mason as a synonym. A key to the species of P. cristata group is presented. Each species is defined and most species are redescribed and/or refigured.
Komai, Tomoyuki, 2004, A new genus and new species of Crangonidae (Crustacea, Decapoda, Caridea) from the southwestern Pacific, Zoosystema, 26, 1, 73–86
Résumé [+] [-]A new cratigonid genus and species, Pseudopontophilus serratus n. gen., n. sp., is established from the southwestern Pacific. The new genus is closely related to Pontophilus Leach, 18 17 and Parapontophilus Christoffersen, 1988 in having at least one pair of lateral teeth oil the rostrum and a postorbital suture on the carapace. It is distinguished from both Pontophilus and Parapontophilus in the completely loss of exopod on the First pereopod and the less reduced second pereopod. Considerable variation in the number of median spines oil the carapace, which not appear to be correlated with either size or sex, is found in this new species.

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

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

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

Résumé [+] [-]French and Australian research expeditions over the past three decades, to the deeper waters of the tropical Pacific Ocean, have encountered a distinctive new octopus. Galeoctopus lateralis is described here from 200-400 in deep in the southern and western Pacific Ocean. This small octopus is recognized by a distinctive jaw-like ligula in mature males, superficially resembling the head and jaws of a shark (complete with teeth-like lugs). Other distinctive characters include a lateral mantle ridge, skin sculpture including stellate papillae, and swollen distal oviducts in females. This combination of characters warrants recognition as a distinct genus. Relationships with other octopodid genera are discussed. We propose that the unique form of the male reproductive organ has evolved as a mechanism for reduction of sperm competition. The mouth-like ligula pit may function to pierce, rupture, grip and/or remove the sperm bulbs of previous suitors from the distal oviducts of the female. This morphology is compared with parallel structures in other cephalopods.
Crosnier, Alain, 2005, Deux Parapenaeus nouveaux (Crustacea, Decapoda, Penaeidae) du Sud-Ouest Pacifique, Zoosystema, 27, 2, 267-266
Résumé [+] [-]During the French cruises conducted in the South-West Pacific during the last 20 years, two new Parapenaeus were found: Parapenaeus kensleyi n. sp., off New Caledonia, Vanuatu and the Fiji Islands; and Parapenaeus cayrei n. sp., off Tonga and the Chesterfield Islands. Amongst the Parapenaeus species provided with a branchiostegal spine on the anterior border of the carapace and extended by a rather long carina, P. kensleyi n. sp., with its long and sinuous rostrum, is related to P. australis Dall, 1957, P. lanceolatus (Bate, 1881) and P. perezfarfante Crosnier, 1986. Parapenaeus cayrei n. sp., with its short and straight rostrum, is related to P. fissurus (Bate, 1881), P. sextuberculatus Kubo, 1949 and P. ruberoculatus Hall, 1962. In both cases, the shape of the distal part of the ventrolateral lobe of the petasma in the males, the arrangement of the lateral bulbous portions and median tubercles, and the bulgings of the thelycum in the females allow the new species to be readily distinguished.

doi: 10.1127/arch.moll/0003-9284/134/129-171 Résumé [+] [-]The genus Granulifusus is distributed over the upper continental shelves in the Indo-West Pacific. The 27 species (21 Recent, 6 fossil) are characterized and separated from Fusinus by a granulated surface sculpture, the Recent also by a small round operculum which does not fill the aperture. Fusus (Sipho) libratus Watson 1886 and Latirus staminatus Garrard 1966 are placed in Granulifusus, their transfer based on the above mentioned conchological characteristics and on radular evidence. Granulifusus niponicus (E.A. Smith 1879), G. kiranus Shuto 1958, G. rubrolineatus (Sowerby II 1870), G. staminatus (Garrard 1966) and G. libratus (Watson 1886) were collected during the Musorstom expeditions and the material is extensively reported on. G. bacciballus sp. nov. (North New Caledonia, 444-452 m), G. benjamini sp. nov. (Coral Sea, Chesterfield, 400 m), G. balbus sp. nov. (South New Caledonia, 470 m), G. amoenus sp. nov. (Vanuatu, 480-544 m), G. geometricus sp. nov. (Tonga Islands, 427-436 m), G. monsecourorum sp. nov. (Madagascar, 240 m) and G. babae sp. nov. (Indonesia, Tanimbar Islands, 206-210 m) were also collected by the Musorstom expeditions and are added to this fauna and described as new species. From the collection of the Australian Museum, Sydney (AMS), one additional Recent species (G. lochi sp. nov., Western Australia, 301-310 m) and one fossil species (G. nakasiensis sp. nov., Nakasi Sandstone Beds, Late Pliocene, Fiji) are described. Lots of the remaining 8 species are studied with the exception of G. captivus (E.A. Smith 1899). The remaining 5 fossil species are listed and compared. G. rufinodis (Von Martens 1901) is tentatively regarded as a distinct species and a lectotype is selected.

Résumé [+] [-]Penaeopsis (Crustacea, Decapoda, Penaeidae) collected in the south-west Pacific by French expeditions since 1976. Description of a new species. This work is based on collections made in the south-west Pacific by IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris. It deals with four species of Penaeopsis Bate, 188 1: P challengeri de Man, 1911, P eduardoi Perez Farfante, 1977, P rectacuta (Bate, 188 1), and a new species, P mclaughlinae n. sp. Depth zones and geographic distributions of the three known species are revised, especially those of P challengeri. Penaeopsis mclaughlinae n. sp. is closely related to P eduardoi but it is easily distinguished by the more sinuous shape of the distal part of the ventrolateral lobules of the petasma, and the large rounded protuberance on the median plate of the thelycum.
Geiger, Daniel L., 2006, Sasakiconcha elegantissima new genus and new species (Gastropoda : Vetigastropoda : Anatomidae?) with disjointly coiled base, The Nautilus, 120, 2, 45-51
Résumé [+] [-]Sasakiconcha elegantissima, a new genus and species from the Western Pacific is described. The specimens are most similar to members of Anatomidae (Anatoma, Thieleella) with a peripheral selenizone, but close the slit to a foramen, and lack a columella because of a disjointly coiled base resulting in an umbilical trough. Additionally, an aberrant specimen of Scissurella morretesi Montouchet, 1972, which shows repeated closure of the slit to form foramina, is discussed with respect to the evolutionary, pathway from the ancestral open slit to its modification as a single or a series of foramina.

Résumé [+] [-]The Pasiphaea alcocki species group is treated herewith, as the third group of the genus Pasiphaea Savigny, 1816. The group is primarily characterized by a deeply concave posterior margin of the telson and the distinctly carinate dorsal margin of the carapace and abdomen. The meri of the first and second pereopods are always armed with many spines, and the ischium and/or basis of the second pereopods are sometimes armed with spines. The group comprises 17 species including two new species both from MUSORSTOM material, Pasiphaea ledoyeri n. sp. and Pasiphaea major n. sp., which are large size species. P. berentsae Kensley, Tranter & Griffin, 1987 is proved to be a junior synonym of P. barnardi Yaldwyn, 1971. P. balssi Burukovsky&Romensky, 1987 is probably a junior synonym of P. rathbunae (Stebbing 1914a). A key to the species of P. alcocki group is presented. Each species is diagnosed and most species are redescribed and/or figured.
Komai, Tomoyuki, 2006, A review of the crangonid genus Lissosabinea Christoffersen, 1988 (Crustacea, Decapoda, Caridea), with descriptions of three new species from the western Pacific, Zoosystema, 28, 1, 31-59
Résumé [+] [-]The crangonid genus Lissosabinea Christoffersen, 1988 was established to accommodate two rare deep-water species: Sabinea indica De Man, 1918 and S. tridentata Pequegnat, 1970 (type species). A study of collections made by French expeditions to the western Pacific, supplemented by material from other sources (including types of both known species), has led to a review of the genus. This Study shows that the hypothesis placing Lissosabinea as a sister group of a clade containing three genera: Vercoia, Prionocrangon and Paracrangon, was derived from an insufficient character analysis. Lissosabinea appears most closely related to Sabinea, as suggested by the original generic assignment of the two known species. Lissosabinea maintains full generic status, as the species referred to the genus are clearly differentiated from the three species assigned to Sabinea by a number of morphological characters. Three new species of Lissosabinea are described: L. armata n. sp. from New Caledonia; L. ecarina n. sp. from the Philippines and Indonesia, and L. unispinosa n. sp. from New Caledonia and Tonga. The two known species are redescribed, and L. indica is newly recorded from New Caledonia. The bathymetric and geographic ranges of the species are briefly discussed. A key to the identification of the species of the genus is presented.
Li, Xinzheng, Bruce, Alexander J., 2006, Further Indo-West Pacific palaemonoid shrimps (Crustacea: Decapoda: Palaemonoidea), principally from the New Caledonian region, Journal of Natural History, 40, 11-12, 611-738
doi: 10.1080/00222930600763627 Résumé [+] [-]Based on the material deposited in the Museum national d'Histoire naturelle, Paris, collected from the Indo-West Pacific, principally from the New Caledonian region, the present paper reports 117 palaemonoid shrimp species, which belong, respectively, to Anchistioididae ( one genus, one species), Gnathophyllidae ( one genus, one species), Palaemonidae Palaemoninae ( seven genera, nine species), and Palaemonidae Pontoniinae ( 30 genera, 106 species), including eight new species. The new species are all Pontoniinae: Mesopontonia brevicarpalis sp. nov., Palaemonella komaii sp. nov., Periclimenes crosnieri sp. nov., Periclimenes forgesi sp. nov., Periclimenes loyautensis sp. nov., Periclimenes paralcocki sp. nov., Periclimenes paraleator sp. nov., and Periclimenes pseudalcocki sp. nov. The last six new species are members of the deep-water "Periclimenes alcocki species complex'', which has more than two ( usually four) pairs of dorsolateral telson spines anterior to the posterior telson margin, the cornea is usually reduced, the dactyl of the major second chela is generally flanged and the chela is sometimes covered with small tubercles. The complex is usually found at more than 200m depth in the West Pacific. The species can be distinguished from each other by the armature of ambulatory propod and dactyl, diameter of cornea, rostrum shape and the number of pairs of dorsolateral telson spines. Mesopontonia brevicarpalis sp. nov., from the southeast coast of Africa, is the seventh species of the genus. Palaemonella komaii sp. nov. is very similar to Palaemonella dolichodactylus Bruce, 1991 and Palaemonella hachijo Okuno, 1999. These three species share the features of very long and slender ambulatory pereiopods with the dactyl more than eight times longer than its basal depth and with several long setae on the dorsal dactylar margin.

Résumé [+] [-]A new genus and species, Choneteuthis tongaensis gen. et sp. nov., is described from the waters around Tonga in the central South Pacific Ocean. The new genus does not clearly fit in any of the currently recognized subfamilies of the family Sepiolidae, justifying a reconsideration of the subfamilial subdivision of the family.

Résumé [+] [-]During the cruise BENTHAUS (November 2002) to the Austral Archipelago (French Polynesia), numerous specimens of galatheids belonging to the genera Agononida Baba & de Saint Laurent, 1996, Munida Leach, 1820, Paramunida Baba, 1988 and Raymunida Macpherson & Machordom, 2000 were collected. The present collection comprises four Agononida species, 26 Munida, two Paramunida and one Raymunida. A new genus, Setanida, is described. The specimens from BENTHAUS cruise were caught in 68 stations between 50 and 1300 m. Additional material from French Polynesia has also been considered. The collection contains 17 new species: Agononida aequabilis, A. imitata, A. simillima, Munida antliae, M. apheles, M. arae, M. columbae, M. descensa, M. erugata, M. fasciata, M. fornacis, M. ignea, M. llenasi, M. oblonga, Paramunida spatula, Raymunida limbata and Setanida cristata.

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

Résumé [+] [-]A new species of the crab genus Cosmonotus Adams & White in White, 1848, Cosmonotus mclaughlinae n. sp., is described from the Indo-West Pacific Ocean. This new species inhabits coarse sand and shell bottoms between 75 and 369 m and is so far known from La Réunion, Philippines, Indonesia (Kai Islands), Salomon, Futuna, Vanuatu, Loyalty Islands (Lifou), Fiji, Tonga (N Ha’apai Group). This new species is morphologically close to C. genkaiae Takeda & Miyake, 1970, from which it is easily separated by: 1) the carapace covered by squamiform tubercles (instead of long striae); 2) the lack of the median rostral process (instead of being present and short); 3) the dorsal carpal face of chelipeds with rounded tubercles (instead of striae); and 4) the slender, eyestalks (instead of stout).

Résumé [+] [-]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.

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.

A revision of Galeodea, Oocorys, Sconsia, Echinophoria and relatedtaxa, with new genera and species (Mollusca, Gastropoda), Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 25, 196, 269-387
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.
Bouchet, Philippe, Petit, Richard E., 2008, New species and new records of southwest Pacific Cancellariidae (Gastropoda), The Nautilus, 122, 1, 1-18
Résumé [+] [-]Fifteen species of Cancellariidae referable to the genera Zeadmete, Admetula, Fusiaphera, Nipponaphera, and Trigonostoma are reported from depths between 200 and 700 m in New Caledonia and other island groups in the southwest Pacific. Twelve are new species: Zeadmete bathyomon new species, Zeadmete physomon new species, Zeadmete bilix new species, Admetula affluens new species, Admetula marshalli new species, Admetula bathynoma new species, Admetula lutea new species, Admetula emarginata new species, Nipponaphera argo new species, Nipponaphera agastor new species, Nipponaphera tuba new species, and Trigonostoma tryblium new species. All the Recent nominal species of Fusiaphera described from localities throughout the Indo-Pacific area Lire considered to be conspecific, the senior name being Fusiaphera macrospira (Adams and Reeve, 1.850), now with ten synonyms. The ranges of Nipponaphera nodosivaricosa (Petuch, 1.979) and Trigonostoma thysthlon Petit and Harasewych, 1987, are extended to the South Pacific.

Résumé [+] [-]Fifty-two deep-water species of Pectinoidea (37 Propeamussiidae, 1 Entoliidae, 14 Pectinidae) are listed from Norfolk Ridge (11 species), Loyalty Islands (4 species), Fiji Islands (30 species), Tonga (26 species), Solomon Islands (26 species) and the Marquesas archipelago (8 species). All species from Fiji, Tonga and the Marquesas are new records and six species of Propeamussiidae are new to science: Propeamussium boucheti (Fiji and Tonga), Parvamussium biformatum (Solomons), Parvamussium lozoueti (Fiji and Tonga), Parvamussium marquesanum (Marquesas), Parvamussium polynesianum (Marquesas) and Similipecten herosae (Tonga). Two new combinations (Hyalopecten tydemani, Talochlamys gladysiae) are introduced.

Résumé [+] [-]Fifty-eight muricid species were collected during recent expeditions to Fiji, including 3 new species. A review of the literature added another 37 species reliably recorded from the archipelago, bringing the total muricid fauna of Fiji to 95 species. Twenty-fi ve species, including 14 shared with Fiji, are reported from Tonga. Bouchetia n. gen. is described for Poirieria (Paziella) vaubanensis Houart, 1986, originally described from New Caledonia and now recorded from Fiji. Conchatalos spinula n. sp. and Prototyphis gracilis n. sp. are described from Fiji; Murexsul merlei n. sp. is described from Fiji and Tonga. Attiliosa caledonica (Jousseaume, 1881), formerly treated as a synonym or subspecies of Attiliosa nodulifera (Sowerby, 1841), is recognized as a valid species, as both species co-occur in Fiji without intermediates. Pascula ambonensis Houart, 1996, Tritonidea lefevreiana Tapparone Canefri, 1880 and Pentadactylus paucimaculatus Sowerby, 1903 are reclassifi ed in Cytharomorula Kuroda, 1953.
Komai, Tomoyuki, 2008, A world-wide review of species of the deep-water crangonid genus Parapontophilus Christoffersen, 1988 (Crustacea, Decapoda, Caridea), with descriptions of ten new species, Zoosystema, 30, 2, 261-332
Résumé [+] [-]A review of species of the genus Parapontophilus Christoffersen, 1988 (Decapoda, Caridea, Crangonidae) from the world oceans is presented. This Study is based on the large collection obtained during French expeditions in the eastern Atlantic, western Indian, and tropical western and southern Pacific oceans, and on additional material from various museums and institutions in the world. Eighteen species, including ten new species, are divided in two informal species groups, P. gracilis (Smith, 1882) group and P modumanuensis (Rathbun, 1906) group. The first group contains I I species: P. gracilis (type species of the genus), P abyssi (Smith, 1884), P. junceus (Bate, 1888), P. profundus (Bate, 1888), P occidentalis (Faxon, 1893), P talismani (Crosnier & Forest, 1973), P cornutus n. sp., P cyrton n. sp., P difficilis n. sp., P. geminus n. sp. and P. longirostris n. sp. The second group contains seven species: P. modumanuensis (Rathbun, 1906), P. demani (Chace, 1984), P caledonicus n. sp., P. juxta n. sp., P. psyllus n. sp., P. sibogae n. sp. and P. stenorhinus in. sp. Six taxa originally described as full species by their authors and occasionally treated as subspecies, viz. P. gracilis, P abyssi, P. junceus, P. profundus, P occidentalis, and P talismani, are here maintained as full species because of the existence of morphological differences and of the partial overlap of geographical or bathymetrical ranges. All species are diagnosed or rediagnosed, and illustrated. Synonymies of Pontophilus challengeri Ortmann, 1893 with Parapontophilus abyssi and of Pontophilus occidentalis var. indica de Man, 1918 with Parapontophilus junceus were con firmed. A key to aid in the identification of all Parapontophilus species is given, although it should be used with caution because of intraspecific variations exhibited by many of the species. Bathymetrical and geographical distributions of species are also summarized. All but P. sibogae n. sp. are exclusively found at more than 200 in depth, and particularly three species, P. abyssi, P occidentalis, and P talismani, occur at abyssal depths exceeding 3000 m. Parapontophilus sibogae inhabits shallow water, recorded at depth of I I m in the type locality. Two species, P gracilis and P talismani, appear restricted to the Atlantic Ocean, although widely distributed there. Three species, P abyssi, P longirostris n. sp., and P. juxta n. sp. occur in the Indian Ocean; P abyssi is also widely distributed in the Atlantic and P longirostris extends to the central Pacific. Parapontophilus occidentalis appears restricted to the eastern Pacific. Other species are distributed in the range of the western Pacific to French Polynesia.

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

Résumé [+] [-]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.

Saito, Tomomi, Komai, Tomoyuki, 2008, A review of species of the genera Spongicola de Haan, 1844 and Paraspongicola de Saint Laurent & Cleva, 1981 (Crustacea, Decapoda, Stenopodidea, Spongicolidae), Zoosystema, 30, 1, 87-147
Résumé [+] [-]A review of species of the deep-sea sponge-associated shrimp genera Spongicola de Haan, 1844 and Paraspongicola de Saint Laurent & Cleva, 1981 (Decapoda, Stenopodidea) is presented on the basis of rich collections made by French expeditions in the Indo-West Pacific, supplemented by collections preserved in various institutions in the world. Seven species are recognized in Spongicola, of which three are new to science: S. venustus de Haan, 1844, S. andamanicus Alcock, 1901, S. levigatus Hayashi & Ogawa, 1987, S. parvispinus Zarenkov, 1990, S. depressus n. sp. from Loyalty Islands, S. goyi n. sp. from Japan, Indonesia, New Caledonia and Vanuatu, and S. robustus n. sp. from Mauritius and Mozambique. Subspecific division of S. andamanicus Alcock, 190 1, proposed by de Saint Laurenr & Cleva (198 1), is abandoned, since our morphological analysis strongly suggests that the division does not reflect a population structure of the species; S. holthuisi de Saint Laurent & Cleva, 198 1, is also reduced to a junior synonym of S. andamanicus. Two species are recognized in Paraspongicola, both previously described, viz. P. pusillus de Saint Laurent & Cleva, 1981 and P. inflatus (de saint Laurent & Cleva, 198 1) n. comb., of which the latter is here transferred from Spongicola. Keys in aid for identification are provided for each genus. Geographic and bathymetric distributions of species are briefly discussed. Association with host sponges was verified for some species.

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

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

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

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.

doi: 10.1111/j.1439-0485.2010.00374.x Résumé [+] [-]This study was carried out to test the hypothesis that benthic communities on seamounts are distinct from those of other deep-sea habitats at comparable depths. Analysis of the squat lobster fauna of deep-sea habitats in the Southwestern Pacific revealed that the species composition of assemblages on seamounts was not statistically dissimilar from assemblages on slope and plateau habitat at comparable depths. However, compositional differences were observed between seamount and rise and ridge habitat. Differences in assemblage composition between seamount and ridge habitat were statistically significant for two of the four ridge systems examined. Assemblages on seamounts that were distinct from non-seamount ridge habitat were typically dominated by small-bodied species with an abbreviated larval stage. Various environmental variables were correlated with the observed assemblage patterns observed; depth-related variables may account for differences between seamount and rise assemblages, whilst differences in POC flux likely play a role in determining the assemblage compositional patterns between seamount and non-seamount ridge habitat. Extensive pre-analysis data treatment was required to ensure that multivariate analyses of assemblage data from seamount and non-seamount habitats were robust. Our results confirm the findings of recent studies that found no compositional differences in assemblages from seamount and slope habitats, and support the idea that dissimilarity between seamount assemblages on different ridge systems increases with geographic distance. Further research will be required before the generality of these findings can be confirmed.

The new taxa not only highlight the diversity of the class in the tropical Pacific Ocean, but also indicate the presence of morphologies not yet recorded for the region or described for the class.
Bouchet, Philippe, Kantor, Yuri I., Sysoev, Alexander V., Puillandre, Nicolas, 2011, A new operational classification of the Conoidea (Gastropoda), Journal of Molluscan Studies, 77, 3, 273-308
doi: 10.1093/mollus/eyr017 Résumé [+] [-]A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s. (16) and Strictispiridae (2). A diagnosis with description of the shell and radulae is provided for each of these families.
De Grave, Sammy, Fransen, Charles H. J. M., 2011, Carideorum catalogus: the recent species of the dendrobranchiate, stenopodidean, procarididean and caridean shrimps (Crustacea: Decapoda), Zoologische Mededelingen, 85, 9
Résumé [+] [-]Over the last decade or so, much has been written on the classification of Decapoda, fuelled by a surge in molecular phylogenetic studies, as well as close scrutiny of internal and external morphological characteristics. As discussed by Fransen & De Grave (2009), such studies on shrimps are still somewhat ”thin on the ground”, at least compared to the more extensive work done on the Brachyura and Anomura. At a higher level in decapod classification it has long been recognised that three distinct lineages of shrimps can be distinguished: Dendrobranchiata, Stenopodidea and Caridea, a system which has not been seriously challenged by recent studies. The internal classification of Dendrobranchiata and Stenopodidea alike has been stable for some time, with the only major addition being the family Macromaxillocarididae Alvarez, Iliffe & Villalobos (2006) to the Stenopodidea in recent years. A different picture has emerged for Caridea very recently with Bracken et al. (2009) and Chan et al. (2010), both drawing attention to the non-monophyletic status of certain superfamilies and families. Further, we are aware of work currently in progress (some by the authors of this compilation) corroborating the hypothesis that the current classification of Caridea is unnatural, lines of study which will lead to the resurrection of certain family names as well as further refinement to other families. As one of our objectives for the current effort was to link this compilation of species level information with the earlier work by Chace (1992) for families and Holthuis (1993a) for genera, we have elected to largely follow the classification outlined by De Grave et al. (2009) which builds upon this earlier work. As such, it was deemed advisable to include the recently resurrected family Acanthephyridae Spence Bate, 1888 in the superfamily Oplophoroidea, rather than in this catalogue to create a new superfamily, which would perhaps be more congruent with the results in Chan et al. (2010). Although we follow herein the classification scheme of De Grave et al. (2009), two recent changes have been implemented. The clarification of the status of Galatheacaris abyssalis Vereshchaka, 1997a, as the megalopal stage of Eugonatonotus chacei Chan & Yu, 1991a, by De Grave et al. (2010) resulted in the removal of the family Galatheacarididae and superfamily Galatheacaridoidea in the current listing. Bracken et al. (2010) clarified the status of the family Procarididae, resulting in the recognition of a fourth group of shrimp, Infraorder Procarididea.
O'Hara, Timothy D., Rowden, Ashley A., Bax, Nicholas J., 2011, A Southern Hemisphere Bathyal Fauna Is Distributed in Latitudinal Bands, Current Biology, 21, 3, 226-230
doi: 10.1016/j.cub.2011.01.002 Résumé [+] [-]The large-scale spatial distribution of seafloor fauna is still poorly understood. In particular, the bathyal zone has been identified as the key depth stratum requiring further macro- ecological research [ 1 ], particularly in the Southern Hemi- sphere [ 2 ]. Here we analyze a large biological data set derived from 295 research expeditions, across an equator- to-pole sector of the Indian, Pacific, and Southern oceans, to show that the bathyal ophiuroid fauna is distributed in three broad latitudinal bands and not primarily differentiated by oceanic basins as previously assumed. Adjacent faunas form transitional ecoclines rather than biogeographical breaks. This pattern is similar to that in shallow water despite the order-of-magnitude reduction in the variability of environmental parameters at bathyal depths. A reliable biogeography is fundamental to establishing a representative network of marine reserves across the world’s oceans [1, 3].

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

Kantor, Yuri I., Puillandre, Nicolas, Rivasseau, Audrey, Bouchet, Philippe, 2012, Neither a buccinid nor a turrid: a new family of deep-sea snails for Belomitra P. Fischer, 1883 (Mollusca, Neogastropoda) with a review of recent Indo-Pacific species, Zootaxa, 3496, 1-64
Résumé [+] [-]The new family Belomitridae is established for the deep-water buccinoid genus Belomitra P. Fischer, 1883, based on morphological (shell and radulae) and molecular evidence. The rachiglossate radula is uniquely characterized by a multicuspid rachidian and lateral teeth with very long narrow bases and two small cusps closer to tip. Molecular analysis of a reduced set of Buccinoidea did not resolve the group as a clade, but shows that Belomitridae forms a well supported clade within Buccinoidea. Species of Belomitra have adult sizes in the 7-53 mm range; they live in deep water, mostly in the 500-2,000 meters range, at low and mid latitudes. Eleven valid species described from the Indo-Pacific were originally named in the families Buccinidae, Columbellidae, Cancellariidae, Volutidae, and Turridae. Fourteen new species are described: Belomitra nesiotica n. sp. (Society Islands to Tonga and Fiji in 580-830 m), B. bouteti n. sp. (Society and Tuamotu Islands in 430-830 m), B. subula n. sp. (Solomon Islands to Vanuatu in 760-1110 m), B. caudata n. sp. (Sulu Sea in 2300 m), B. gymnobela n. sp. (South Pacific, eastern Indonesia and Philippines in 780-2040 m), B. hypsomitra n. sp. (Fiji in 392-407 m), B. brachymitra n. sp. (Fiji in 395-540 m), B. comitas n. sp. (Madagascar and Philippines in 1075-1110 m), B. minutula (Coral Sea in 490 m), B. granulata n. sp. (New Caledonia in 105-860 m), B. reticulata n. sp. (Tonga and Fiji to New Caledonia in 395-656 m), B. decapitata n. sp. (Indian Ocean and New Caledonia in 3680-4400 m), B. admete n. sp.

Résumé [+] [-]Stomatopod Crustacea of the superfamily Squilloidea collected primarily by the Philippine AURORA expedition are reported. One family, nine genera and 15 species are reported, of which one genus and two species are new to science. The new genus, Triasquilla n. gen., comprising two new species, belongs to the “Meiosquilla” group within Squillidae and is most closely allied to Schmittius Manning, 1972, from the eastern Pacific and Squilloides Manning, 1968, from the Indo-West Pacific. Anchisquilla fasciaticauda Liu & Wang, 1998, Cloridina chlorida (Brooks, 1886), Harpiosquilla sinensis Liu & Wang, 1998, Neclorida miersi (Manning, 1968) and Quollastria ornata (Manning, 1971) are reported from the Philippines for the first time. The study is supplemented by additional material of the new species described herein collected from various Indo-West Pacific localities by other deep-sea expeditions to the Philippines, Solomon Islands, New Caledonia, Vanuatu, Fiji, Tonga and Western Australia.

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

Résumé [+] [-]Recent French deep-sea expeditions in the Indo-West Pacific resulted in the collection of abundant material of the deep-sea lobster genus Puerulus Ortmann, 1897 (Palinuridae). Difficulties in identification necessitated a generic revision and as a result, five new species are described, all of which are similar to P. angulatus (Bate, 1888). Puerulus angulatus was thought to have a wide distribution from eastern Africa to Marquesas Islands, but is now restricted to the western Pacific, from Japan to Australia. Of the five new species, P. gibbosus n. sp. is found in eastern Africa, P. mesodontus n. sp. from Japan to Fiji, P. richeri n. sp. from the New Caledonia to Marquesas Islands, while P. sericus n. sp. and P. quadridentis n. sp. mainly occur around New Caledonia. Of the other three previously described species, the distribution of P. velutinus Holthuis, 1963, is extended to Fiji, while P. sewelli Ramadan, 1938, and P. carinatus Borradaile, 1910, are still only known from the northern and western parts of the Indian Ocean, respectively. COI gene sequence differences support the morphological species distinctions.
Messing, Charles G., 2013, A revision of the genus Atelecrinus PH Carpenter (Echinodermata: Crinoidea), Zootaxa, 3681, 1, 1-43
doi: 10.11646/zootaxa.3681.1.1 Résumé [+] [-]The unusual bathyal comatulid crinoid genus Atelecrinus is widespread in the Atlantic and tropical Pacific Oceans and currently includes three recognized species. A re-assessment based on examination of new and existing specimens requires establishment of two new genera and five new species, and returns three junior synonyms to species-level status. Paratelecrinus is erected to accommodate Atelecrinus wyvilli PH Carpenter, A. conifer AH Clark, A. cubensis PH Carpenter, P. orthotriremis, new species, P. amenouzume new species, P. laticonulus new species and P. telo new species. Adelatelecrinus is erected to accommodate Atelecrinus sulcatus AH Clark and Adelatelecrinus vallatus new species. Atelecrinus retains A. balanoides PH Carpenter and A. helgae AH Clark, which restricts the genus to the Atlantic. In both Paratelecrinus and Adelatelecrinus, the basals articulate with the centrodorsal via ligament bundles anchored in deep ring-like interradial pits that project into the centrodorsal cavity, whereas in Atelecrinus the centrodorsal rim has shallow interradial concavities and attaches to the basals via a tight junction with no obvious ligament bundles. The spoon-shaped aboral fossa in the basals of Paratelecrinus appears to be unique among articulate crinoids and differs from the smooth fossa found in both Atelecrinus and Adelatelecrinus. New material extends the range of the family to the Indian Ocean. A few species are now known from enough specimens to identify some ontogenetic and distributional variations. Proximal ray morphology varies substantially with size in P. cubensis and P. orthotriremis. A. balanoides generally occurs in deeper water in the Lesser Antilles than in the Bahamas and Strait of Florida, while P. orthotriremis occurs in shallower water in the Lesser Antilles and deeper in the Bahamas.

doi: 10.1016/j.ympev.2012.09.018 Résumé [+] [-]Although the status of Crinoidea (sea lilies and featherstars) as sister group to all other living echinoderms is well-established, relationships among crinoids, particularly extant forms, are debated. All living species are currently placed in Articulata, which is generally accepted as the only crinoid group to survive the Permian–Triassic extinction event. Recent classifications have recognized five major extant taxa: Isocrinida, Hyocrinida, Bourgueticrinina, Comatulidina and Cyrtocrinida, plus several smaller groups with uncertain taxonomic status, e.g., Guillecrinus, Proisocrinus and Caledonicrinus. Here we infer the phylogeny of extant Crinoidea using three mitochondrial genes and two nuclear genes from 59 crinoid terminals that span the majority of extant crinoid diversity. Although there is poor support for some of the more basal nodes, and some tree topologies varied with the data used and mode of analysis, we obtain several robust results. Cyrtocrinida, Hyocrinida, Isocrinida are all recovered as clades, but two stalked crinoid groups, Bourgueticrinina and Guillecrinina, nest among the featherstars, lending support to an argument that they are paedomorphic forms. Hence, they are reduced to families within Comatulida. Proisocrinus is clearly shown to be part of Isocrinida, and Caledonicrinus may not be a bourgueticrinid. Among comatulids, tree topologies show little congruence with current taxonomy, indicating that much systematic revision is required. Relaxed molecular clock analyses with eight fossil calibration points recover Articulata with a median date to the most recent common ancestor at 231–252 mya in the Middle to Upper Triassic. These analyses tend to support the hypothesis that the group is a radiation from a small clade that passed through the Permian–Triassic extinction event rather than several lineages that survived. Our tree topologies show various scenarios for the evolution of stalks and cirri in Articulata, so it is clear that further data and taxon sampling are needed to recover a more robust phylogeny of the group.
Roux, MICHEL, Eléaume, Marc, Hemery, Lenaïg G., Améziane, Nadia, 2013, When morphology meets molecular data in crinoid phylogeny: a challenge, Cahiers de Biologie marine, 54, 541-548
Résumé [+] [-]The extant crinoid fauna results from more than 485 Myr of evolution (from Early Ordovician). Detailed morphological studies on extant crinoids document large intraspecific variations, strong changes through ontogeny with various mosaics of heterochronic development, and adaptive characters which depend on environment, mainly hydrodynamics and food supply. The importance of paedomorphy and morphological convergences (homoplasies) in crinoid evolution is confirmed by studies using DNA markers, and makes difficult the use of cladistic methods of phylogenetic reconstructions. Many clades of extant crinoids based on external skeleton morphology are polyphyletic. Using the hyocrinids and a recent extensive molecular phylogeny of the extant crinoids, we show that the molecular approach, when coupled with detailed ontogenetic analyses on a large sample of specimens and taxa, may help understand the evolutionnary trends within a given group of organisms. Purely molecular or phenotypic analyses produce contrasting results because these analyses work at scales that are separated by a strong gap. We propose a deep reappraisal of the relationships between extant and fossil taxa using the concept of onto phylogeny which rejects the classical separation between ontogeny and phylogeny and argues that natural selection acts at every level of integration of the organism from DNA, cells, tissues, to the individuals and populations.

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).

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

doi: 10.11646/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.

doi: 10.11646/zootaxa.3826.1.8 Résumé [+] [-]A new genus, Arxellia, is described in the family Solariellidae. Nine species are referred to this taxon, eight of which are new and are described in this paper (Arxellia trochos n. sp., Arxellia boucheti n. sp., Arxellia herosae n. sp., Arxellia helicoides n. sp., Arxellia tracheia n. sp., Arxellia thaumasta n. sp., Arxellia maestratii n. sp. And Arxellia erythrea n. sp.). The previously described species Bathymophila tenorioi Poppe, Tagaro & Dekker, 2006 is reassigned to Arxellia.

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.

doi: 10.1111/zsc.12097 Résumé [+] [-]The commercial deep-sea penaeid shrimp genus Parapenaeus contains 15 species, three subspecies and two forms in the Indo-West Pacific and the Atlantic. Novel nucleotide sequence data from five different genes (COI, 16S, 12S, NaK and PEPCK) were collected to estimate phylogenetic relationships and taxonomic status amongst all but one subspecies in this genus. The phylogenetic results only support two of the four species groups previously proposed for this genus and indicate an evolution direction of the genital organs from simple to complex. The present results suggest that Parapenaeus originated in the shallow waters of the West Pacific with subsequent migration to the deep sea and the Atlantic. The molecular data reveal that there was probably misidentification of females between Parapenaeus australiensis and Parapenaeus ruberoculatus, with females previously assigned as P. australiensis likely being the females of P. ruberoculatus, while material identified as P. australiensis forma nodosa being the true P. australiensis females. On the other hand, Parapenaeus longipes forma denticulata truly represents a variation of the same species, while the subspecies Parapenaeus fissuroides indicus warrants a specific rank.

Résumé [+] [-]The 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.
