Castro, Peter, Crosnier, Alain, 2000, Crustacea Decapoda: A revision of the Indo-West Pacific species of palicid crabs (Brachyura Palicidae)), Résultats des campagnes MUSORSTOM, Mémoires du Muséum national d'Histoire naturelle, 21, 184, 437-610
Résumé [+] [-]The taxonomy of the crabs belonging to the family Palicidae Bouvier, 1898 from the Indo-west Pacific region is revised. On the basis of extensive material collected by French expeditions in the Coral Sea and other regions of the Pacific and Indian oceans, as well as material from numerous museums, including most of the types, the present study recognizes two subfamilies, 10 genera, and 43 species. Of these taxa, four are new genera: Exopalicus, Miropalicus, Paliculus, and Rectopalicus. Manella is synonymized with Crossotonotus A. Milne Edwards, 1873. Parapleurophricoides Nobili, 1906, sometimes believed to be a palicid, is a xanthoid and it is removed from the Palicidae. Nine nominal species described by previous authors are synonymized and an additional 17 species are described.
Anseeuw, Patrick, Poppe, Guido T., 2001, Description of Perotrochus boucheti sp. nov. from the South Pacific (Gastropoda: Pleurotomariidae), Novapex, 2, 4, 125-131
Résumé [+] [-]P. boucheti is closely related to other Perotrochus species from the Indo-West Pacific such as P. africanus Tomlin, 1948, P. teramachii Kuroda, 1955, P. tangaroana Bouchet & Métivier, 1982 and P. westralis (Whitehead, 1987). Consistent differences in colour of teleoconch and base, sculptural pattern of basal disc and selenizone, shape of aperture and proportion of surface area covered by the umbilical region callus pad on basal disc allow separation on specific level. This represents the fourth species of living Perotrochus in the South Pacific.

Kosuge, Sadao, Oliverio, Marco, 2001, A new Coralliophiline species from the Southwest Pacific (Neogastropoda : Muricidae : Coralliophilinae), Journal of Conchology, 37, 3, 285-290
Résumé [+] [-]A new coralliophiline species with striking morphological features is described from several stations sampled in deep waters off New Caledonia. It is compared with related species of Babelomurex and Hirtomurex. It is currently known only from a restricted area in the south-west Pacific.
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.
Holthuis, Lipke Bydeley, 2002, The Indo-Pacific scyllarine lobsters (Crustacea, Decapoda, Scyllaridae), Zoosystema, 24, 3, 499-683
Résumé [+] [-]A revision is provided of the Indo-Pacific species of the subfamily Scyllarinae. All of these species were formerly placed in the genus Scyllarus Fabricius, 1775, but a closer study revealed that several genera could be distinguished within the subfamily. The 13 new genera now recognized in the Indo-Pacific biogeographic region are as follows: Acantharctus n. gen., Antarctus n. gen., Antipodarctus n. gen., Bathyarctus n. gen., Biarctus n. gen., Chelarctus n. gen., Crenarctus n. gen., Eduarctus n. gen., Galearctus n. gen., Gibbularctus n. gen., Petrarctus n. gen., Remiarctus n. gen. and Scammarctus n. gen. Diagnoses and keys are provided for all the genera and their species. New and insufficiently known species have been described extensively, for the others additional morphological details are given. New species are: Bathyarctus chani n. gen., n. sp., B. steatopygus n. gen., n. sp., Petrarctus veliger n. gen., n. sp., Chelarctus crosnieri n. gen., n. sp., Eduarctus pyrrhonotus n. gen., n. sp., E. marginatus n. gen., n. sp., E. perspicillatus n. gen., n. sp. and E. reticulatus n. gen., n. sp. Furthermore efforts were made to provide each species with a complete synonymy, a description of the colour, its biology, habitat and geographical distribution. All the material examined is listed in detail. Where appropriate, remarks are provided on nomenclature, published data on the larval development and other topics.
Lorenz, Felix, 2002, New worldwide Cowries. Descriptions of new taxa and revisions of selected groups of living Cypraeidae (Mollusca: Gastropoda), ConcBooks, 19
Résumé [+] [-]This book describes taxa of cowries, some of which are new to science; others have to date been known only by taxonomically invalid forma-names: valid species: aenigma, colligata, deforgesi. New species by revision and promoting of rank: valid species: aenigma, colligata, deforgesi. New species by revision and lifting of rank: boucheti, gilvella, johnsonorum. New subspecies: caurica samoensis, citrina dauphinensis, coronata debruini, decipiens suprasinum, exmouthensis abrolhoensis, e. magnifica, jeaniana thalamega, katsuae guidoi, maculifera martybealsi, m. scindata, mappa admirabilis, teramachii polyphemus, langfordi cavatoensis, stolida brianoi, subteres violacincta, teres janae, and new subspecies by taxonomic validation: bregeriana pervelata, cinerea brasilensis, connelli peelae, cribraria australiensis, exmouthensis rottnestensis, fimbriata marquesana, fuscodentata grohorum, f sphaerica, mappa aliwalensis, pellucens panamensis, porteri nigromaculata, rosselli latistoma, r. satiata, scurra mundula, teramachii neocaledonica. Taxonomically valid names of other authors are elevated to species rank: exmouthensis, geographica, pellucens, and in some cases, to subspecies rank: cribraria zadela, fuscorubra gondwanalandensis, teres alveolus. Some genera and species-complexes are discussed in detail: the Leporicypraea mappacomplex, some species of the deep-water genus Nesiocypraea, the Western Australian members of Cribrarula, the genus Cypraeovula and its zoogeography, Erronea caurica and its subspecies, and the Blasicrura (Talostolida) teres species-complex. The distributions of all new taxa and related species-complexes are shown. In an illustrated checklist, all species, subspecies and commonly used forma-names of the living Cypraeidae are listed, including the new species and subspecies described herein.
Valdés, Ángel, 2002, Phylogenetic systematics of " Bathydoris " s.l. Bergh, 1884 (Mollusca, Nudibranchia), with the description of a new species from New Caledonian deep waters, Canadian Journal of Zoology, 80, 6, 1084-1099
doi: 10.1139/z02-085 Résumé [+] [-]There are six valid species in the traditional genus Bathydoris, all of them found in polar or deep waters: Bathydoris abyssorum Bergh, 1884 (from the deep equatorial Pacific Ocean), Bathydoris ingolfiana Bergh, 1899 (from Greenland), Bathydoris hodgsoni Eliot, 1907 (from Antarctic and subantarctic waters), Bathydoris clavigera Thiele, 1912 (from the Argentinean deep-sea basin and Antarctica), Bathydoris aioca Ev. Marcus and Er. Marcus, 1962 (from deep waters off California), and a new species, Bathydoris spiralis (from deep waters off New Caledonia). Bathydoris patagonica Kaiser, 1980 and Bathydoris violacea Baranets, 1993 are regarded as synonyms of B. hodgsoni and B. clavigera, respectively. Bathydoris spiralis is clearly distinguishable from other members of the genus mainly in having a triaulic reproductive system and a very elongated, spirally coiled deferent duct. Examination of the holotype of B. violacea revealed that it is a synonym of B. clavigera. Bathydoris vitjazi Minichev, 1969 is most likely a synonym of B. hodgsoni, but is provisionally regarded as nomen dubium until more material becomes available. The phylogenetic hypothesis supports the monophyly of the Anthobranchia but shows that the genus Bathydoris is paraphyletic. Species of Bathydoris are divided into two clades, one of them also containing the phanerobranch and cryptobranch dorids. Bathydoris type species B. abyssorum retains its name and diagnosis, but B. clavigera and B. spiralis are excluded from this genus. They are, however, provisionally maintained in "Bathydoris" s.l., a likely paraphyletic group. This result shows some incongruities between the traditional nomenclatural system and phylogenetic systematics.
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.
Kelly, Michelle, 2003, Revision of the sponge genus Pleroma Sollas (Lithistida: Megamorina: Pleromidae) from New Zealand and New Caledonia, and description of a new species, New Zealand Journal of Marine and Freshwater Research, 37, 1, 113-127
doi: 10.1080/00288330.2003.9517151 Résumé [+] [-]Diagnostic morphological characters for the sponge genus Pleroma, relicts from a diverse group of lithistid sponges (Suborder Megamorina: Family Pleromidae) that were once common in the north-western European late Jurassic to the late Cretaceous (c. 140-65 Ma), are reviewed following examination of new collections of known species from northern New Zealand and the south New Caledonian slope. Before this work, only two living species of Pleroma were known, the genus holotype P. turbinatum Sollas from Fiji, and P. menoui Levi & Levi from south New Caledonian seamounts. A new species, P. aotea n. sp., is described from northern New Zealand waters, extending the suite of diagnostic characters to include nodulose megaclone desmas and amphiaster microscleres. Megaclone desmas, indistinguishable from those of P. menoui and P. aotea n. sp., are recorded from the Oamaru Diatomite in southern New Zealand (late Eocene), and the Tutuiri Greensand, Chatham Island (late Palaeocene), respectively. These published and new microfossil discoveries establish a disjunct geographic distribution for Pleroma in New Zealand.

Résumé [+] [-]Three new coralliophiline species are described from stations sampled in deep waters of New Caledonia, and Fiji in the South West Pacific: Coralliophila rhomboidea, Babelomurex virginiae and Mipus coriolisi. All species are compared with the morphologically closest species of Coralliophila, Babelomurex and Mipus.
Bamber, Roger N., 2004, Pycnogonids (Arthropoda: Pycnogonida) from French cruise to Menalesia, Zootaxa, 551, 1-27
Résumé [+] [-]Seventy specimens of pycnogonid from New Caledonia and the Solomon Islands, collected during cruises from the Paris Museum, are described. No pycnogonids have been recorded previously from the Solomon Islands. Of the sixteen species identified, three ammotheids, Bathyzetes umbrella, Cilunculus cymobostrychos and C. mergus, are new to science. The distinctions of the sibling species Colossendeis pipetta Stock, 1991 and C. sinuosa Stock, 1997 are analyzed morphometrically. The pycnogonid fauna of the Melanesia-Micronesia-Polynesia region is summarized.
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.
Cohen, Bernard L., Améziane, Nadia, Eleaume, Marc, Richer de Forges, Bertrand, 2004, Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea), Marine Biology, 144, 3, 605-617
doi: 10.1007/s00227-003-1212-7 Résumé [+] [-]We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by phylogenetic methods. The molecular data were compiled from concatenated nuclear-encoded 18S rDNA, internal transcribed spacer 1, 5.8S rDNA, and internal transcribed spacer 2, together with part of mitochondrial 16S rDNA, and comprised 3,593 sites, of which 313 were parsimony-informative. The molecular and morphological analyses include data from the bourgueticrinid Bathycrinus; the antedonid comatulids Dorometra and Florometra; the cyrtocrinids Cyathidium, Gymnocrinus, and Holopus; the isocrinids Endoxocrinus, and two species of Metacrinus; as well as from Guillecrinus and Caledonicrinus, whose ordinal relationships are uncertain, together with morphological data from Proisocrinus. Because the molecular data include indel-rich regions, special attention was given to alignment procedure, and it was found that relatively low, gene-specific, gap penalties gave alignments from which congruent phylogenetic information was obtained from both well-aligned, indel-poor and potentially misaligned, indel-rich regions. The different sequence data partitions also gave essentially congruent results. The overall direction of evolution in the gene trees remains uncertain: an asteroid outgroup places the root on the branch adjacent to the slowly evolving isocrinids (consistent with palaeontological order of first appearances), but maximum likelihood analysis with a molecular clock places it elsewhere. Despite lineage-specific rate differences, the clock model was not excluded by a likelihood ratio test. Morphological analyses were unrooted. All analyses identified three clades, two of them generally well-supported. One well-supported clade (BCG) unites Bathycrinus and Guillecrinus with the representative (chimaeric) comatulid in a derived position, suggesting that comatulids originated from a sessile, stalked ancestor. In this connection it is noted that because the comatulid centrodorsal ossicle originates ontogenetically from the column, it is not strictly correct to describe comatulids as "unstalked" crinoids. A second, uniformly well-supported clade contains members of the Isocrinida, while the third clade contains Gymnocrinus, a well-established member of the Cyrtocrinida, together with the problematic taxon Caledonicrinus, currently classified as a bourgueticrinid. Another cyrtocrinid, Holopus, joins this clade with only weak molecular, but strong morphological support. In one morphological analysis Proisocrinus is weakly attached to the isocrinid clade. Only an unusual, divergent 18S rDNA sequence was obtained from the morphologically strange cyrtocrinid Cyathidium. Although not analysed in detail, features of this sequence suggested that it may be a PCR artefact, so that the apparently basal position of this taxon requires confirmation. If not an artefact, Cyathidium either diverged from the crinoid stem much earlier than has been recognised hitherto (i.e., it may be a Palaeozoic relic), or it has an atypically high rate of molecular evolution.
Kool, Hugo H., 2004, Nassarius olomea Kay, 1979, revalidated (Gastropoda, Caenogastropoda, Nassariidae), Basteria, 68, 21-24
Résumé [+] [-]Contrary to data in the literature, Nassarrius alomea Kay, 1979, has a much wider distribution than only the Hawaiian Islands. It occurs also in parts of the southwestern Pacific. Nassarius alamen and N. crebricostatus (Schepman, 1911) are shown to be separate species.
Mah, Christopher, 2005, A phylogeny of Iconaster and Glyphodiscus (Echinodermata, Asteroidea, Valvatida, Goniasteridae) with descriptions of four new species, Zoosystema, 27, 1, 137-161
Résumé [+] [-]A phylogenetic analysis of 11 taxa and 31 characters resulted in a single most parsimonious tree that supports monophyly of the goniasterid genera Iconaster and Glyphodiscus. Four new species, Glyphodiscus magnificus n. sp., Glyphodiscus pentagonalis n. sp., Iconaster uchelbeluuensis n. sp., and Iconaster vanuatuensis n. sp., are described and two species are synonymized. At least three species within the genus Iconaster appear to have invaded shallower water from a deeper-water ancestry. Glassy tubercles, similar to those interpreted as photoreceptors in ophiuroids and other goniasterids, are present in the shallow-water Iconaster clade. Glassy tubercles are largely absent in the deeper-water sister and outgroup taxa, suggesting their occurrence is related to photic zone or shallow-water occupation. Biogeographic patterns as presently known suggest that diversification in Iconaster and Glyphodiscus has been restricted to the central and south Pacific regions.
Norman, Mark D., Hochberg, F. G., Boucher-Rodoni, renata, 2005, A revision of the deep-water Octopus genus Scaeurgus (Cephalopoda: Octopodidae) with description of three new species from the southwest Pacific ocean, Journal of Molluscan Studies, 71, 4, 319-337
doi: 10.1093/mollus/eyi033 Résumé [+] [-]Deep-water trawl surveys on seamounts around New Caledonia yielded 62 specimens of the little-known genus, Scaeurgus. Members of this genus of octopuses typically occur at depths of 200-500 m in temperate and tropical latitudes worldwide. Prior to this study, Scaeurgus was considered to contain one to two species. The new material from New Caledonia contained a surprising diversity of Scaeurgus species from a small area: three distinct new species are described and limited material of a further two taxa is reported. A pygmy member of this genus is reported for the first time. Distributions of these new taxa are consistent with reports of high endemism on the seamount systems in this region. Fifty-eight of the 62 specimens were collected from seamounts, with four of the five taxa unique to a single seamount.
Vilvens, Claude, 2005, New records and new species of Calliostoma and Bathyfautor (Gastropoda: Calliostomatidae) from the Vanuatu, Fiji and Tonga, Novapex, 6, 1-2, 1-17
Résumé [+] [-]New records of Calliostoma and Bathyfautor from Vanuatu, Fiji and Tonga are listed. Calliostoma (Fautor) strobilos n. sp., C. (F.) chlorum n. sp., C. (F.) metabolicum n. sp., C. (Ampullotrochus) xylocinnamomum n. sp. and C. (Benthastelena) arx n. sp. are described and compared with several similar Calliostoma species from the Indo-Pacific of which most are illustrated.
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.
Snyder, Martin Avery, Hadorn, Roland, 2006, A new bathyal Fusinus (Mollusca: Gastropoda: Fasciolariidae) from New Caledonia, Zootaxa, 1311, 1-12
Résumé [+] [-]A new bathyal species of Fusinus is described from New Caledonia. Fusinus laviniae new species is distinguished from other New Caledonia Fusinus by its long siphonal canal and angular sculpture. This new species is compared to F. colus (Linnaeus, 1758), F. nicobaricus (Roding, 1798), F. nobilis ( Reeve, 1847), F. salisburyi Fulton, 1930, F. similis (Baird, 1873), and F. undatus, (Gmelin, 1791). A range extension for F. nobilis to New Caledonia is noted.
Kelly, Michelle, 2007, The Marine Fauna of New Zealand: Porifera: lithistid Demospongiae (Rock Sponges), NIWA Biodiversity Memoir, 121, 1-100
Résumé [+] [-]The lithistid Demospongiae fauna of New Zealand has been inventoried from existing and new collections, and is reviewed here and revised where necessary. Most of the 282 specimens examined were recorded from the largest collection of sponges in New Zealand, in the NIWA Invertebrate Collection, Wellington. Significant collections were also examined from the Museum of New Zealand Te Papa Tongarewa. The lithistid Demospongiae (formerly order Lithistida Schmidt, 1870) is represented in the New Zealand region by nine families, 18 genera (one of which is new to science), and 30 species (12 of which are new to science): Theonellidae (1 genus, 1 species), Phymatellidae (3 genera, 6 species), Corallistidae (3 genera, 7 species), Neopeltidae (4 genera, 4 species), Macandrewiidae (1 genus, 1 species), Pleromidae (1 genus, 3 species), Isoraphiniidae (1 genus, 1 species), Scleritodermiidae (3 genera, 5 species), and Azoriciidae (1 genus, 2 species). This work records the first lithistid species, Neoschrammeniella antarctica n. sp., known from polar regions, and provides the first record of the genus Leiodermatium further south than the Philippines. Two additional species of Leiodermatium described here are found only in the west-central Pacific and Micronesian deep waters, but are included for the sake of a complete review of the genus in the Pacific. New species of the previously monospecific phymatellid genera Neoaulaxinia and Neosiphonia are described, and a new corallistid genus, Awhiowhio, is recognised from New Zealand waters. All specimens were dredged from between 80 and 1700 m, but were commonest between 200 and 800 m. With the exception of one specimen from the eastern edge of the Challenger Plateau on New Zealand’s west coast, and a new species from the Ross Sea, Antarctica, all were found north of the southern edge of the Chatham Rise and in New Zealand’s northernmost waters. Known and new species are redescribed from representative New Zealand material and, in some cases, the characters used to define genera and species are redefined and clarified. In particular, ornamentation of the desma skeleton and morphology of the augmenting microscleres are emphasised for distinction at the species level.

How far to go?, Tropical Deep-Sea Benthos, Mémoires du Muséum national d'Histoire naturelle, 25, 196, 9-40
Résumé [+] [-]The Institut de Recherche pour le Développement (IRD, formerly ORSTOM) and Muséum national d’Histoire naturelle (MNHN) launched in the early 1980s a suite of oceanographic expeditions to sample the deep-water benthos of the tropical South and West Pacific, with emphasis on the 100-1,500 m bathymetric zone. This paper reviews the development of this programme to date. It describes the procedures involved in curating the material collected and the involvement of an international network of taxonomic experts to identify, describe and name the molluscan fauna. So far, 1,028 species of molluscs have been recorded from the New Caledonia Exclusive Economic Zone from depths below 100 m, and 601 of these (58.4%) were new species. An additional 142 new species have been described from other South Pacifi c island groups (Solomon Islands, Vanuatu, Fiji, Wallis and Futuna, Tonga, Marquesas Islands and Austral Islands). However, the hyper-diverse families have essentially remained untouched. Regional differences among island groups are high, and New Caledonia, which has been sampled best, shows several discrete areas of micro-endemism. We speculate that the deep-sea mollusc fauna of New Caledonia may amount to 15-20,000 species, and the corresponding number for the whole South Pacifi c may be in the order of 20-30,000 species.

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

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 [+] [-]Study of deep-water chitons from around New Caledonia and Vanuatu has revealed 35 species, of which 25 species were identified to species and 10 only to genus. This article includes 7 new records for this area of which 4 are described as new species: Ischnochiton crassus Kaas, 1985, Stenosemus robustus Kaas, 1991, S. herosae n. sp., Connexochiton discernibilis Kaas, 1991, Loricella vanbellei n. sp., L. eernissei n. sp. and L. dellangeloi n. sp. In addition, Vermichiton vermiculus Kaas, 1991 is reviewed. Based on available biogeographic data it is proposed that Loricella originated off South Australia during the Oligocene, in a time of global cooling. Later, Loricella extended its range north up to Taiwan and east to Tonga, most likely remaining in the bathyal zone. These new discoveries add to the already high diversity and high proportion of endemics known from this region, and a speculative interpretation of these patterns is offered in conclusion.
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 species of anglerfish, Chaunax nudiventer, is described on the basis of 35 specimens from the western South Pacific Ocean. It is characterized by large spots on the dorsal surface; a largely naked area on abdomen; a relatively short head and long tail, both reflected in the elongated body; slender and simple spines on body surface; numerous broad flaps on lateral side of body; and higher number of lateral line neuromasts: mainly 41–43 in lateral line proper, 4 in the upper peropercular series, and 16–17 in the pectoral series. Comments on a similar species, C. latipunctatus from the eastern South Pacific Ocean, is provided.

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.

doi: 10.1016/j.dsr.2011.03.008 Résumé [+] [-]Seamounts were often considered as‘hotspots of diversity’ and ‘centers of endemism’,but recently this opinion has been challenged. After 25 years of exploration and the work of numerous taxonomists, the Norfolk Ridge (Southwest Pacific) is probably one of the best-studied seamount chains worldwide. However,even in this intensively explored area, the richness and the geographic patterns of diversity are still poorly characterized. Among the benthic organisms,the post-mortem remains of mollusks can supplement live records to comprehensively document geographical distrbutions. Moreover, the accretionary growth of mollusk shells informs us about the lifes pan of the pelagic larva.To compare diversity and level of endemism between the Norfolk Ridge seamounts and the continental slopes of New Caledonia we used species occurrence data drawn from (i) the taxonomic literature on mollusks and (ii) a raw dataset of mainly undescribed deep-sea species of the hyperdiverse Turridae. Patterns of endemism and species richness were analyzed through quantitative indices of endemism and species richness estimates or metrics.To date, 403 gastropods and bivalves species have been recorded on the Norfolk Ridge seamounts. Of these, at least 38 species(10%) are potentially endemic to the seamounts and nearly all of 38 species have protoconchs indicating lecithotrophic larval development. Overall, our results suggest that estimates of species richness and endemism ,when sampling effort is taken into account, were not significantly different between slopes and seamounts. By including in our analyses 347 undescribed morphospecies from the Norfolk Ridge, our results also demonstratet he influence of taxonomic bias on our estimates of species richness and endemism.

doi: 10.1071/IS11022 Résumé [+] [-]The primary purpose of DNA-barcoding projects is to generate an efficient expertise and identification tool. This is an important challenge to the taxonomy of the 21st century, as the demand increases and the expert capacity does not. However, identifying specimens using DNA-barcodes requires a preliminary analysis to relate molecular clusters to available scientific names. Through a case study of the genus Eumunida (Decapoda : Eumunididae), we illustrate how naming molecule-based units, and thus providing an accurate DNA-based identification tool, is facilitated by sequencing type specimens. Using both morphological and unlinked molecular markers (COI and 28S genes), we analysed 230 specimens from 12 geographic areas, covering two-thirds of the known diversity of the genus, including type specimens of 13 species. Most hypotheses of species delimitation are validated, as they correspond to molecular units linked to only one taxonomic name (and vice versa). However, a putative cryptic species is also revealed and three entities previously named as distinct species may in fact belong to a single one, and thus need to be synonymised. Our analyses, which integrate the current naming rules, enhance the a-taxonomy of the genus and provide an effective identification tool based on DNA-barcodes. They illustrate the ability of DNA-barcodes, especially when type specimens are included, to pinpoint where a taxonomic revision is needed.
Beu, Alan G., Bouchet, Philippe, Tröndlé, Jean, 2012, Tonnoidean gastropods of French Polynesia, Molluscan Research, 32, 2, 61-120
Résumé [+] [-]The tonnoidean gastropod fauna of French Polynesia (54 species) includes 26 species recorded from the Austral Islands (including 10 from Rapa), 33 species from the Marquesas Islands, 39 from the Society Islands, 32 from the Tuamotu Islands, and 3 from the Tarava Seamounts. Most species have planktotrophic larval development and are distributed from East Africa to eastern Polynesia, but many common western Pacific species are not present. With the possible exception of Semicassis salmonea n. sp. (Cassidae), described from the Marquesas, and Gyrineum pusillum (Ranellidae), restricted to the Austral (and Tuamotu?) Islands in southeastern-most Polynesia, no species is endemic to any individual island groups, but several species with broad overall ranges are known from only one archipelago within French Polynesia. Three species (Monoplex intermedius, Septa peasei, Ranellidae; Distorsio graceiellae, Personidae) are much more common in the Marquesas Islands than further westwards. Three species of Bursidae (Bursa lamarckii, Bursina nobilis, Tutufa tenuigranosa) are recorded only from the Marquesas Islands, whereas the only record of Bursina fijiensis is from the Austral Islands. The two very similar species Bursa asperrima and B. cruentata have a complex distribution; only B. cruentata is common west of Hawaii, and only B. asperrima occurs east of Hawaii, but only B. cruentata has been collected at the Marquesas Islands. Ranella venustula is a synonym of Bursa rhodostoma. Neotypes are designated for Buccinum ponderosum Gmelin, 1791, B. nodulosum Gmelin, 1791, Cassis caputequinum Röding, 1798, C. denticulata Röding, 1798, C. glabra Röding, 1798, C. hamata Röding, 1798, Phalium edentulum Link, 1807, P. quadratum Link, 1807, Buccinum biarmatum Dillwyn, 1817, B. pantherina Dillwyn, 1817, Cassis tenuilabris Menke, 1828, and Dolium rufum Blainville, 1829, and lectotypes are designated for Buccinum cornutum Linnaeus, 1758, Murex bufonius Gmelin, 1791 and Cassis torquata Reeve, 1848.

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

doi: 10.11646/zootaxa.3620.1.4 Résumé [+] [-]Species of the anglerfish genus Chaunax Lowe, 1846 from the New Zealand region are taxonomically reviewed with six species recognized and described: Chaunax penicillatus McCulloch; C. nudiventer Ho & Shao, a new record for New Zealand; and four species new to science. Chaunax flavomaculatus sp. nov. distinguished by having its skin covered with a mix of numerous bifurcated and simple spinules, large yellow spots on dorsal surface of fresh specimens, and brownish coloured escal cirri; Chaunax mulleus sp. nov. by having a uniformly pink body with a deep red colour on ventral surfaces of the outer pectoral-fin and pelvic-fin, and lower part of caudal fin; Chaunax reticulatus sp. nov. by having cirri on the dorsal surface of head, and a pale reticulate colour pattern on a greyish background dorsally; and Chaunax russatus sp. nov. by its very wide illicial trough that is usually as wide or wider than the diameter of the pupil, and uniformly deep red body colour with creamy white to fuzzy greyish spots or patches on its dorsal surface. A key to species recognized from the study area is given.

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.

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.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.4044.3.3 Résumé [+] [-]Descriptions of three new species of the aulopid genus Hime from the central and western Pacific and presumably the easternmost Indian Ocean are presented. Hime surrubea sp. nov., confined to the Hawaiian Island region, has been misidentified in species accounts and faunal lists as H. japonica and although resembling it is separable from that species by its shorter caudal peduncle, slightly larger head, larger eye, especially relative to head size, and slightly smaller pectoral and pelvic fins. Hime capitonis sp. nov. is known conclusively only from seamounts off the southern tip of New Caledonia and Vanuatu, and is distinguishable by its distinctively large head (32.3–35.6% SL) and eyes (orbital diameter 10.8–13.0% SL) and relatively few scales between the anus and anal fin origin (7–9). The Indonesian H. caudizoma sp. nov. is so far known from only 8 specimens, acquired in markets in southeastern Lombok and presumably caught nearby in what would be regarded the eastern reaches of the Indian Ocean. The species is recognisable by its dorsal fin of rather uniform moderate height with nearly straight distal margin and 17 rather than 16 rays, none of which is filamentous in either sex, the second penultimate ray rather than anterior rays the longest in males. Like the other two described here, H. caudizoma has among the largest head and eyes of the family. Observations on the dorsal fin form and other features of H. microps Parin & Kotlyar, 1989 are provided based on a large male specimen collected at Rapa Iti, Austral Islands and a re-evaluation of the original description.

doi: 10.11646/zootaxa.3999.2.5 Résumé [+] [-]Parapercis johnsoni sp. nov. is described based on 19 specimens from Marquesas Islands, French Polynesia. It differs from congeners in having a combination of the following characters: dorsal-fin rays V, 21; anal-fin rays I, 17; pectoral-fin rays modally 17; pored lateral-line scales modally 52 or 53; predorsal scales 7 or 8; transverse scale rows 3.5 or 4 + 14 or 15; total gill rakers on 1st gill arch 13–16; single row of teeth on vomer; 6 large canines at front of lower jaw; and a distinct coloration. Two rare species, P. flavescens Fourmanoir & Rivaton, 1979 and P. fuscolineata Fourmanoir, 1985, are redescribed based on the types and newly identified specimens. Comments on other species occurring in the area are provided.
