Tangaroa 4-28 novembre 1996), 151
Résumé [+] [-]The exploratory bottorn trawling survey HALIPRO 2 was carried out from 4 to 28 November 1996 on board the New Zealand research vessel Tangaroa of NIWA (National Institut ofWater and Atrnospheric Research Ltd). It was aimed at identification of deep fishery resources over the Norfolk Ridge and the southern part of the Loyalty Ridge. This zone, the area of which is 73000 square km, was previously rnapped during the seabed rnapping survey ZoNéCo 1. A trawl similar to the one used by the New Zealand commercial deep bottom fishing boats was used. Amongst 35 persons on board, 17 were scientists from different countries with different fields of research. A total of 3755 nautical miles were covered and 106 hauls were made. The environment was studied through temperature and salinity profils down to 1500 m and CUITent records down to 300 ffi. The presence of alfonsino (Beryx splerulens) was confirmed over the summits of the seamounts where this species was exploited by bottom longlining from 1988 to 1991. Hauls made over slopes and plains did not allow the catch of any specimen of orange roughy (Hoplostethus atlanticus). Hard and rough bottoms on the summits and flanks of the seamounts make awkward the use of bottom trawls. HALIPRO 2 showed the high species diversity of the fauna (275 species of fish belonging to 101 families). In particular, 42 different species of shark and ray were collected of which 40% are new to science. Many samples were collected for further analysis. This survey will no doubt remain a perfect exemple of a fruitful collaboration with New Zealand.

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

Résumé [+] [-]The exploratory fishing survey ZoNéCo 6 was canied out on board the R.Y. Alis of the IRD (Institut de Recherche pour le Développement) from 1-14 Décember 1998. lts main objective was to show whether commercial fish resources are present at depths between 300 and 800 m on the outer reef slopes of the Fairway-Lansdowne Bank and the Chesterfield Atoll. Two fishing techniques were used, bottom trawling and bottom longlining. The choice of fishing spots was based on both acoustic surveys using a 28 kHz FURUNO FCY 292 and the bathymetric charts produced during the seabed mapping survey ZoNéCo 4 canied out by the R.Y. L'Atalante. The duration of the trip was splitted into 41, l % devoted to transit, 27 % to bathymetry, 22.3 % to fishing and 9,6 % to waste of time due to bad weather conditions. 17 fishing stations were completed of which 9 were trawl hauls and 8 bottom longline sets amounting to a fishing effort close to 5000 hooks. Three trawl stations and 3 longline sets were made on the slopes of the Chesterfield Atoll whilst 6 trawl stations and 5 longline sets were completed on the slopes of the Fairway-Lansdowne Bank. The total catch was 822 kg of which 243 kg were caught with the trawl and 579 kg with the longline. The trawl did not catch any commercial species, shark amounting to 42 % of the catch, bone fishes 40 %, Crustaceans 9 % and Cephalopods 9 %. The average trawl catch rate was 0,6 tonne/km2 (6,06 kg/ha). The only commercial species caught with the longline were « red snappers» Etelis . carbunculus and E coruscans amounting to 211 kg (36,4 % of the total weight) with a catch rate of 4,3 kg/100 hooks. Sharks dominated the catch both in terms of number and weight (320 kg amounting to 55,3 % of the catch). Gnly one Beryx splendens was caught. With the exception of « red snappers », the survey did not show the presence of commercial target resources within the 300-800 m depth range of the prospected area.
Grandperrin, René, Richer de Forges, Bertrand, 1999, Programme «Monts sous-marins» (1990-2000) Bilan final, 49
Résumé [+] [-]Le programme «Monts sous-marins» s'est déroulé au centre IRD de Nouméa depuis 1990 sous la direction de René GRANDPERRIN. Ses objectifs étaient l'étude faunistique des pentes récifales externes, des monts sous-marins et du domaine bathyal supérieur (200-1500 m) et l'évaluation de leurs potentialités halieutiques. 32 campagnes représentant un total de 446 jours de mer ont été effectuées. 18 d'entre elles ont été consacrées à l'halieutique, 13 aux études faunistiques et une à des essais de sondeur. 1496 opérations de prélèvement ont été réalisées (445 pour l'halieutique et 1051 pour la faunistique) avec les engins suivants: casier, chalut à crevettes, chalut de fond à poissons, grand chalut de fond à poissons néo-zélandais, chalut à perche, chalut pélagique à poissons, drague épibenthique, drague à roche, drague Waren et palangre de fond. En ce qui concerne l'halieutique, les ressources des pentes externes (100-600 m) ont été étudiées en Nouvelle-Calédonie et à Vanuatu, archipel pour lequel un atlas des pêches est sous presse. Les monts sous-marins agissent comme des dispositifs de concentration de poissons pour les espèces démersales. En Nouvelle-Calédonie, ils abritent une ressource en Beryx splendens qui fit l'objet d'une exploitation commerciale. Une étude scientifique, basée sur Il campagnes, a pennis de déterminer les paramètres biologiques et dynamiques de l'espèce et de modéliser sa distribution en fonction de la profondeur. Pour la première fois, une corrélation liant la croissance d'un poisson de profondeur avec le phénomène ENSO a été établie. Des travaux de génétiques des populations sont en cours sur cette espèce. Par ailleurs, le programme «Monts sous-marins» collabora étroitement avec le programme ZoNéCo d'identification et d'évaluation des ressources marines de la zone économique de Nouvelle-Calédonie. Deux synthèses portant sur les données thonières et sur les poissons profonds furent réalisées. Un halieute participa aux campagnes de bathymétrie mettant en œuvre un sondeur multifaisceaux à bord du N.O. L'Atalante. Cinq campagnes d'exploration des ressources halieutiques profondes furent effectuées à bord du N.O. Alis à l'aide de chaluts et de palangres de fond. Elles mirent en évidence l'existence de certaines ressources jusque là ignorées des pêcheurs. Les collectes de la faune bathyale ont été réalisées dans le cadre d'opérations conjointes IRD et Muséum national d'Histoire naturelle (MNHN). L'analyse des prélèvements a été possible grâce à un réseau de taxonomistes mis en place par l'IRD (Centre de Nouméa et Antenne du MNHN) et le MNHN ; il compte 181 chercheurs appartenant à 92 institutions de 24 nations différentes, ce qui représente un effort de recherche internationale exceptionnel! Les résultats obtenus dans le Pacifique sud-ouest, et notamment en Nouvelle-Calédonie, ont révolutionné la connaissance de la biodiversité des faunes profondes. 20 volumes des Résultats des campagnes MUSORSTOM qui paraissent dans la série des Mémoires du Muséum national d'Histoire naturelle sont déjà parus (environ 10 000 pages) et un autre est sous presse. Ils traitent de plus de 4500 espèces dont plus de 1300 étaient nouvelles pour la science. 126 genres nouveaux ont été créés de même que 7 familles nouvelles. Au sein de cette étude, la Nouvelle-Calédonie apparaît comme particulièrement riche en espèces et d'une très grande originalité puisque sur-les 1619 espèces actuellement publiées, 60,7 % étaient nouvelles pour la science. Des études phylogénétiques ont été réalisées sur certains groupes zoologiques en utilisant soit des techniques de biologie moléculaire (ADN), soit des méthodes de microscopie électronique. Il s'agit des Crustacés, des Echinodermes (Crinoïdes) et des Brachiopodes, parmi lesquels plusieurs formes panchroniques ont été découvertes. L'accessibilité aux faunes de profondeurs au cours du programme «Monts sous-marins» a permis de récolter des organismes qui ont fait l'objet d'analyses par le programme de pharmacologie (Substances Marines d'Intérêt Biologique: SMIB). Deux bases de données sont directement issues des travaux du programme «Monts sous-marins». Elles concernent les données halieutiques et les données faunistiques. Les premières ont été stockées à la Structure de Gestion et de Valorisation Locale (SGVL) du programme ZoNéCo. Les secondes le sont à l'IRD. Pour chacune d'elles, une procédure de création de sites INTERNET est en cours. Le problème majeur rencontré par le programme fut la disponibilité en personnel. En effet, avec une moyenne de 6 personnes, dont un chercheur et un ingénieur d'étude à plein temps, les effectifs ne dépassèrent jamais un total de 9! Le programme disposa en moyenne de 318 kFlan, dont 40 % sur fonds IRD et 60 % sur financements extérieurs. Les financements extérieurs furent de trois types: FIDES section locale du Territoire de Nouvelle-Calédonie, programme ZoNéCo et, dans une moindre mesure, MAE. Le nombre de publications réalisées par les ressortissants du programme a été de 214, dont 139 pour lesquelles le premier auteur est un membre du programme.

Résumé [+] [-]Within the framework of the programme "ZoNéCo" of evaluation of the marine resources of the economic zone of New Caledonia, a series of operations were completed in the southeastern part of Ihe economic zone. The first was a balhymetrical and geophysical survey of the major part of the Norfolk Ridge and the southem end of Ihe Loyalty Ridge. The data obtained on this survey provided a base for the preparation and completion of the deep-sea trawling survey "HALIPRO 2", the main objective of which was 10 search for commercial quantities of deep-sea fish, primarily orange roughy (Hoplostethus atlanticus). During this survey, 106 hauls were made between 230 and 1,860 m depth. A total catch of 263 fish species was made belonging to 192 genera and 101 families. In particular, 37 species of sharks and rays were collected of which 40% are new to science. The results confinn the extreme specific richness of the deep-sea ichthyofauna and the presence of species of commercial interest such as the alfonsino, Beryx splendens. However, orange roughy, was not located.

Résumé [+] [-]Apristurus albisoma is described from New Caledonia all depths ranging from 935 10 1,564 m. The description is based on 21 type specimens which include immature and mature males and females. Ranging from 328 to 596 mm in total length. This new species is distinguishable from other species of the genus by the following characters: small eyes and wide interorbital region; the latter being 2.7-3.6 times eye diameter: first dorsal fin originating above middle of pelvic-fin base: second dorsal-fin axil before anal-fin axil: upper labial furrows equal to, or shorter than lower furrows: overlapping tricuspid dermal denticles: 6- 10 spiral valves: continuous supraorbital sensory canal: body whitish.
Roberts, Clive D., Grande, Terry C., 1999, The sandfish, Gonorynchus fosteri (Gonorynchidae), from bathyal depths off New Caledonia, with notes on New Zealand specimens, Société Française d'Ichtyologie, 195-205
Résumé [+] [-]The Australasian sandfish, Gonorynchus forsteri Ogilby, is recorded for lhe first time from the New Caledonian Exclusive Economic Zone (EEZ). The record is based on two adult specimens, one running ripe female and one spent or resting male, captured at 960-1233 m depth on the Loyalty Island Ridge and Lord Howe Rise. Their presence in bathyal depths over 700 nautical miles from the nearest known populations is discussed and compared with the occurrence of the species in New Zealand waters. It is hypothesized that adult sandfish migrate along oceanic ridges to spawn in southern New Caledonian waters.

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

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

Résumé [+] [-]Molecular markers allow insights into the population biology and ecology of deep-sea organisms, which are usually hardly accessible to direct observation and poorly known. Such a study was undertaken here for the deep-sea fish Beryx splendens, a species of growing interest to fisheries. B. splendens populations were sampled on seamounts and continental margins in the southwestern Pacific (New Caledonia, New Zealand, southeastern Australia) and in the northeastern Atlantic. Two hundred and fifty individuals were characterised by their single-strand DNA conformation (SSCP) of a z 360-base-pair (bp) fragment of the mitochondrial cytochrome b gene, amplified by the polymerase chain reaction (PCR). Two major SSCP haplotypes were observed in New Caledonia, a and w, whose frequencies were negatively correlated along a north-tosouth cline. All SSCP haplotypes in the total sample were sequenced on 273 bp. The phylogenetic tree of B. splendens haplotype sequences, rooted by two B. decadactylus sequences, showed that a and w belong to distinct mitochondrial clades, A and W, which are separated by z 4–6 % nucleotide divergence. Thirty individuals from New Caledonia were characterised by their DNA fingerprint from arbitrary-primed PCR. The distribution of individual-pairwise similarity indices was strongly bimodal. The larger similarity values all corresponded to comparisons within a clade (A or W) while the lower values were all between clades. Therefore, there was a strict association between the mitochondrial type and the DNA (presumably, nuclear DNA) fingerprint of an individual. Altogether, these results point to the existence of two biological species (sp. A and sp. W) within the current taxon B. splendens. No within-species differentiation was detected at the regional scale (New Caledonia). A remarkable result is that the three cytochrome b haplotypes of northeastern Atlantic B. cf. splendens sp. A were also the three commonest in the southwestern Pacific populations of this species. Such a level of homogeneity in the distribution of haplotypes suggests there is, or recently has been, gene flow at the inter-oceanic scale.

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

Résumé [+] [-]We reported in an earlier paper the great species richness of the grenadier fauna (families Bathygadidae and Macrouridae) from recent bathyal trawl collections made mainly during MUSORSTOM cruises in the New Caledonian region. Here we add information from further samples to complement earlier taxonomic findings, and descriptions of 2 new species, together with comments on species, distribution and ecology. Thus a total of 2055 specimens from 221 samples examined representing 20 genera and 63 species were found to have closest similarity in composition with New South Wales, Western Australia and New Zealand. As expected, dissimilarity increased with distance from New Caledonia. Four genera dominated in species richness: Caelorinchus (17), Hymenocephalus (8), Nezumia (5) and Ventrifossa (6), comprising 2/3 of the total fauna. The generic make-up of the faunas closest to New Caledonia were most consistent with that region; propordons varied radically from there in the more distant regions invesdgated. Bathymetrically, the smaller trawls of the MUSORSTOM surveys collected grenadiers over a range of tows shallower than that reflected by the commercial gear used on the HALIPRO 2 cruise, with a generally smaller size of fish sampled. Co-occurrence of grenadier species within similar depth strata on the slope was remarkably high, with only two of the 63 species not represented, at least over part of their depth range, in the upper 1600 m. Species richness peaked at 37 in both the 700 and 800 tn strata, although it did not drop below 20 across the depth range 400-1100 m and reduced substantially only deeper than 1400 m.

Résumé [+] [-]During the "MUSORSTOM" cruises in the southwestern Pacific, and particulariy off New Caledonia, 19 species of Hexactinellida Amphidiscophora have been found. Twelve species are considered as new: Hyalonema spatlia, H. uncinata, H. microstauractina, Sericolophus calsubus, S. neocaledonicus, Semperella abyssalis, S. crosnieri, S. varioactina foliopogon micropentactinus, P. claviculus, P. zonecus, and Pheronema pseudogiganteum. Iwo other new species were collected near Hawaii: Sericolophus hawaiicus and off eastern Australia: Sericolophus cidancus. The description of the holotype of Pheronema giganteum Schulze is completed.

Résumé [+] [-]Twenty nine specimens of the rare deep-sea shrimps Bathypalaemonellidae, just represented until now by few species and specimens (nine species, gathered in only one genus, Bathypalaemonella Balss, 1914) have been collected during different cruises, that occured, on the one hand, in the east Atlantic (Ibero-Moroccan Gulf: BALGIM-84, 1984, and SEAMOUNT 1, 1988; Açores, BIACORES, 1971), and on the other hand, mainly in the Pacific Ocean: Philippines (MUSORSTOM 2 , 1980); Indonesia (KARUBAR, 1991); New Caledonia (BIOCAL, 1985; MUSORSTOM 4, 1985; SMIB 2, 1986; VOLSMAR, 1989; HALIPRO 2, 1996); Vanuatu (MUSORSTOM 8, 1994); Marquesas islands, French Polynesia (MUSORSTOM 9, 1997), and another specimen from the Gulf of Aden (SCIMEROUAD, 1977), that prove to belong to a new species, Bathypalaemonella adenensis n. sp., which can be separated from the seven other species maintained in the genus Bathypalaemonella, by the feature of the scaphocerite (the latero-distal spine overreaches significantly the distal margin of the blade), and of the telson, ended by three pairs of spines. Seven species have been collected: apart from Bathypalaemonella adenensis n. sp., these are: Bathypalaemonella serratipalma Pequegnat, 1970; B. hayashii Komai, 1995; B. cf. humilis Bruce, 1966; B. pandaloides (Rathbun, 1906); B. brevirostris Bruce, 1986; B. pilosipes Bruce, 1986. Bathypalaemonetes n. gen. is established for the last two species mentionned above, Bathypalaemonella brevirostris and B. pilosipes, which can be separated from the species of the genus Bathypalaemonella by a set of features such as: cephalothorax with at the most one postrostral spine; major second pereopod with the ischium shorter than the merus, and its fingers showing a serie of tubercles; minor second pereopod with the dactyl far less shorter than the palm. A key to the genera and species of the family is proposed.

Résumé [+] [-]Three species of chimaeroid fishes are reported from deep waters around New Caledonia: Chimaera phantasma, Rhinochimaera pacifica and Hydrolagus trolli n. sp., which is described from 23 specimens collected from New Caledonia and New Zealand at depths of 612 - 1707 m. The new species is distinguished from all other members of the genus by its blue-gray coloration, distinctly pointed snout, first dorsal fin concave along its posterior edge with a pale margin, preopercular and oral lateral-line canals usually sharing a common branch, males with a robust frontal tenaculum with the distal bulb upturned at its distal edge, denticles extending onto the dorsal surface and bifid pelvic claspers with the distal 1/3 divided and pale colored, fleshy distal lobes.

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

Résumé [+] [-]During recent deep-sea expeditions in Taiwan, Japan and New Caledonia seven specimens were collected of the rare pandalid shrimp Bitias brevis (Rathbun, 1906), a species previously known from only two specimens. The study of this new material showed that characters used in separating B. brevis from its sole congeneric species, B. stocki Fransen, 1990, are variable. This study provides additional information on this rare shrimp, including coloration.

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.
Karmovskaya, Emma S., 2003, New records of synaphobranchid eels (Synaphobranchidae, Anguilliformes) collected off New Caledonia and adjacent regions, with description of a new species of Atractodenchelys, Journal of Ichthyology, 43, 7, 491-500
Résumé [+] [-]Eight species of benthopelagic synaphobranchid eels (Synaphobranchidae, Synaphobranchus affinis, S. brevidorsalis, S. oregoni, Diastobranchus capensis, Haptenchelys texis, Meadia abyssalis, Dyssomina rugoso, and Atroctodenchelys robinsorum sp. nova) were collected during MUSORSTOM cruises in 1985- 1986 and 1994-1999 off New Calcdonia and adjacent underwater rises. Descriptions are given for the two monotypic genera Haptenchelys and Atractodenchelys, previously known only from the North Atlantic and thus recorded for the first time in the Pacific, and two new species, M. abyssallis and D. rugosa, for the first time recorded in the south western Pacific. A description of the new species, A. robinsorum sp. nova, is provided based on three specimens collected in the mesobenthic zone off Chesterfield and Vanuatu Islands. The new species is distinct from its Atlantic counterpart A. phrix by the greater number of vertebrae ( 186-199 vs. 16X-172), greater number of vomcrine tceth (7-8 vs. 5), greater number of pores in supraorbital and infraorbital canals, and lower number of pores in prcopcrcular-mandibular canal.
Séret, Bernard, Last, Peter, 2003, Description of four new stingarees of the genus Urolophus (Batoidea: Urolophidae) from the Coral Sea, South-West Pacific, Cybium, 27, 4, 307-320
Résumé [+] [-]Four new species of urolophid stingarees are described from the Coral Sea (South-West Pacific): Urolophus deforgesi sp. nov. and U. papilio sp. nov. from the continental slope of the Chesterfield Islands; U. neocaledoniensis sp. nov. is more widely distributed on the slopes of the Chesterfield Islands and New Caledonia and along the northern part of the Norfolk Ridge; U. piperatus sp. nov. is restricted to the coast of northern Queensland (Australia). The holotype and only known specimen of a rare and unusual stingaree, U. annatus Val. in Muller & Henle, 1841 from New Ireland (Bismark Archipelago), is redescribed and it could represent a new genus. The new species are mainly distinguished by a combination of the following characters: disc shape (particularly its width), dorsal fin (present or absent), interorbital distance (narrow or broad), tail length (short or elongated), coloration (plain or with spots), and oral papillae, vertebrae and pectoral-fin radial counts. A key for the urolophids of the Coral Sea is provided.
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.
Crosnier, Alain, Dall, William, 2004, Redescription of Hymenopenaeus obliquirostris (Crustacea, Decapoda, Penaeoidea, Soleneceridae) and descriptions of two new species of Hymenopenaeus from the Indo-West Pacific, Zootaxa, 600, 1-26
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.
Hayashi, Ken-Ichi, Marshall, Bruce A., Richer de Forges, Bertrand, 2004, Revision of the Pasiphaea cristata Bate, 1888 species group of Pasiphaea Savigny, 1816, with descriptions of four new species, and referral of P. australis Hanamura, 1989 to Alainopasiphaea Hayashi, 1999 (Crustacea: Decapoda: Pasiphaeidae), Mémoires du Muséum national d'Histoire naturelle, 23, 191, 319-373
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.
Karmovskaya, Emma S., 2004, Benthopelagic bathyal Conger eels of families Congridae and Nettastomatidae from the western tropical Pacific, with descriptions of ten new species, Journal of Ichthyology, 44, Suppl. 1, 1-32
Résumé [+] [-]The results are presented of a study of the collection of congrid (18 species) and nettastomatid (4 species) eels collected by the MUSORSTOM and other expeditions on the underwater rises and island slopes in the western tropical part of the Pacific Ocean. The following new species were described: three species of the genus Ariosoma (A. sereti and A. multivertebratum from the waters of the Marquesas Islands and A. sazonovi from the waters of the Philippines), two species of the genus Gnathophis ( G. neocaledoniensis from New Caledonia and G. asanoi from the Philippines), and one species each from the genera Parabathymyrus (P fijiensis from the Fiji Islands), Congriscus (C. marquesaensis from the Marquesas Islands), Acromycter (A. longipectoralis from the waters of New Caledonia), Blachea (B. longicaudalis from Fiji and New Caledonia), and Saurenchelys (S. taiwanensis from the waters of Taiwan). The validity of Ariosoma howensis (McCulloch & Waite), Gnathophis heterognathos (Bleeker), and Macrocephenchelys brevirostris (Chen & Weng) is confirmed. For the first time, C. maldivensis, P adenensis, and D. polystigmatus, known earlier only by occurrences in the Indian Ocean, were recorded in the western part of the Pacific Ocean.
Komai, Tomoyuki, Marshall, Bruce A., Richer de Forges, Bertrand, 2004, A review of the Indo-West Pacific species of the genus Glyphocrangon A. Milne-Edwards, 1881 (excluding the G. caeca species group) (Crustacea: Decapoda: Caridea: Glyphocrangonidae), Mémoires du Muséum national d'Histoire naturelle, 23, 191, 375-610
Résumé [+] [-]A review of the species of the caridean genus Glyphocrangon A. Milne-Edwards, 1881 from the Indo-West Pacific Oceans is presented based on rich collections formed during French expeditions to various regions, and supplemented by extensive material deposited in various institutions throughout the world. The genus is divided into two informal groups primarily based on the development of the eye and the presence or absence of arthrobranchs on the first and second pereopods. This study treats species characterized by a well-developed eye and the presence of arthrobranchs on the first and second pereopods (herein called the Glyphocrangon spinicauda species group). A total of 54 species are recognized in the G. spinicauda species group from the Indo-West Pacific region. Of these, the following 28 are new to science: G. albatrossae (Philippines), G. amblytes (Madagascar and South Africa), G. armata (New Caledonia, Vanuatu, Fiji, Wallis and Futuna islands), G. boletifera (Gulf of Aden), G. chacei (Philippines), G. confusa (Indonesia), G. cornuta (New Caledonia), G. crosnieri (Madagascar), G. conodactylus (New Caledonia), G. dimorpha (New Caledonia), G. ferox (Madagascar), G. formosana (Taiwan and East China Sea), G. indonesiensis (Philippines and Indonesia), G. kapala (eastern Australia), G. saintlaurentae (western Indian Ocean), G. major (New Caledonia), G. lineata (Indonesia and northwestern Australia), G. parva (Philippines), G. perplexa (Japan and Taiwan), G. proxima (Philippines and Indonesia), G. punctata (Philippines), G. richeri (Wallis and Futuna islands), G. robusta (Philippines), G. rubricinctuta (Wallis and Futuna islands), G. runcinata (East China Sea), G. similior (Coral Sea), G. speciosa (New Caledonia), and G. tasmanica (Tasman Sea). Glyphocrangon andamanensis Wood-Mason & Alcock, 1891 and G. mabahissae Calman, 1939, which have been considered to be synonymous with G. investigatoris Wood-Mason in Wood-Mason & Alcock, 1891 and G. dentata Barnard, 1926 respectively, are found to be distinct species. Glyphocrangon juxtaculeata Chace, 1984, the holotype of which is a juvenile, is considered to be a junior subjective synonym of G. regalis Bate, 1888. Glyphocrangon joani Allen & Butler, 1994 is treated as a junior synonym of G. fimbriata Komai & Takeuchi, 1994. Plastocrangon Alcock, 1901 is interpreted as a synonym of Glyphocrangon. The new species are fully described and illustrated, and all but three of the previously known species are redescribed and illustrated: G. gilesii and G. smithii being diagnosed on the basis of published information, G. unguiculata Wood-Mason in Wood-Mason & Alcock, 1891 on published information and provisionally identified material from the western Pacific. One obscurely diagnosed species, G. wagini Burukovsky, 1990 from the southeastern Pacific, is also redescribed in order to establish its affinities. Lectotypes are designated for G. acuminata Bate, 1888, G. pugnax de Man, 1918, G. assimilis de Man, 1918, G. sibogae de Man, 1918, and G. megalophthalma de Man, 1918. Identification key, separated by sex, is provided. This study reveals that most Glyphocrangon species have restricted geographical ranges, with only G. caecescens occurring in both the western Pacific and Indian oceans. The geographic and bathymetric distributions of the treated species are summarized.

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 [+] [-]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.
Hayashi, Ken-Ichi, Richer de Forges, Bertrand, Justine, Jean-Lou, 2006, Revision of the Pasiphaea alcocki species group (Crustacea, Decapoda, Pasiphaeidae), Mémoires du Muséum national d'Histoire naturelle, 24, 193, 193-241
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, Richer de Forges, Bertrand, Justine, Jean-Lou, 2006, Revision of the Glyphocrangon caeca species group (Crustacea, Decapoda, Glyphocrangonidae), Mémoires du Muséum national d'Histoire naturelle, 24, 193, 243-264
Résumé [+] [-]A review of the species of the Glyphocrangon caeca Wood-Mason & Alcock, 1891 group is presented based on samples obtained during French expeditions to the southwestern Pacific and western Indian Ocean, and supplemented with materials deposited in various museums and institutions in the world. Eight species are now recognized in this species group. The two previously described species, G. caeca from the Bay of Bengal and G. cerea Alcock & Anderson, 1894 from the Laccadive Sea, are rediagnosed based on literature, as types or supplemental topotypic specimens of these two species have not been available for study. Six new species are described: G. brevis n. sp. from Madagascar, G. demani n. sp. from Indonesia, G. humilis n. sp. from Japan and Taiwan, G. musorstomia n. sp. from Wallis and Futuna Islands, Vanuatu, Fiji and Chesterfield Islands, G. parviocullus n. sp. from New Caledonia, and G. rudis n. sp. from the Solomon Islands. Species of this group occur exclusively in the Indo-West Pacific. The horizontal and bathymetric distributions of the species are briefly summarized. The available data suggests that species of the group are highly localized.
Lemaitre, Rafael, 2006, Two new species of Parapaguridae (Crustacea, Decapoda, Anomura, Paguroidea) with subconical corneas, and new data on biology of some rare species, Zoosystema, 28, 2, 517-532
Résumé [+] [-]Two new parapagurid species with subconical corneas, Oncopagurus conicus n. sp. and Paragiopagurus schnauzer n. sp., are described based on collections by French expeditions to New Caledonia, the Philippines and Solomon Islands, in the western Pacific. These represent the 16th and 18th documented species of Oncopagurus Lemaitre, 1996 and Paragiopagurus Lemaitre, 1996, respectively. Two other parapagurids are known to have subconical corneas, Sympagurus acinops Lemaitre, 1989, and Oncopagurus minutus (Henderson, 1896). Also reported are specimens of two rare and morphologically unique parapagurids, Typhlopagurus foresti de Saint Laurent, 1972 and Bivalvopagurus sinensis (de Saint Laurent, 1972), and represent geographical and bathymetric range extensions for both species. The diagnoses of the monotypic genera Typhlopagurus and Bivalvopagurus are to be modified due to new data on morphology and biology. The former genus was given to include T.foresti, wrongly assumed to lack cornea, thus presumed blind; and the latter for B. sinensis, prematurely assumed to exclusively use bivalve shells as housing.
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.
Lin, Feng-Jiau, 2006, Two New Axioids (Decapoda: Thalassinidea) from New Caledonia, Journal of Crustacean Biology, 26, 2, 234-241
Résumé [+] [-]Two new species of Axioidea were found amongst the deep-sea material recently collected from New Caledonia. Meticonaxius dentatus sp. nov. is unique among members of the genus by the presence of the teeth on the rostrum and the merus of the large cheliped. Oxyrhynchaxius tricarinatus sp. nov. is the third species known in the genus and is unique in bearing three dorsal ridges on the abdome
Macpherson, Enrique, 2006, New species and new occurrences of Galatheoidea (Crustacea, Decapoda) from New Caledonia, Zoosystema, 28, 3, 669–681
Résumé [+] [-]Four new species of the genera Eumunida Smith, 1883 (E. spinosa n. sp.), Munida Leach, 1820 (M. aulakodes n. sp., M. devestiva n. sp.) and Torbenia Baba, 2005 (T. calvata n. sp.) are described and illustrated from specimens collected during recent cruises carried out off New Caledonia. Eumunida spinosa n. sp. has two well developed spines on the anterior border of the fourth thoracic sternite (subgenus Eumunida de Saint-Laurent & Poupin, 1996), the posterior region of the carapace with complete striae, the carapace with two pairs of anterolateral spines, no ventral pad on the propodus of the chelipeds, and two rows of well developed spines on the palm of the cheliped. Munida aulakodes n. sp. is characterized by the presence of three spines on the branchial lateral margins of the carapace, spines on the anterior ridge of the second abdominal somite, and two carinae separated by a furrow, on each lateral part of the seventh thoracic sternite. Munida devestiva n. sp. has a carapace without complete transverse ridges, small eyes, with the corneae barely wider than the eyestalk, and the abdominal segments unarmed. Torbenia calvara n. sp. is easily differentiated from the other species of the genus by the absence of spines on the anterior ridge of the second abdominal segment, and the small size of the first anterolateral spine of the carapace. A new occurrence of the rare species Pseudomunida fragilis Haig, 1979 is also reported.
O’Hara, Timothy, Stöhr, Sabine, Richer de Forges, Bertrand, Justine, Jean-Lou, 2006, Deep water Ophiuroidea (Echinodermata) of New Caledonia: Ophiacanthidae and Hemieuryalidae, Mémoires du Muséum national d'Histoire naturelle, 24, 193, 33-141
Résumé [+] [-]Ophiuroids of the families Ophiacanthidae (46 species) and Hemieuryalidae (2 species) are monographed for the region around New Caledonia in the southwest Pacific Ocean. Ophiohamus nanus n. gen. n. sp. is described in the Ophioplinthacinae. New species are also described in the following genera: Ophiacantha (O. fuscina n. sp., O. richeri n. sp.), Ophioplinthaca (O. amezianeae n. sp.), Ophiomitrella (O. mensa n. sp., O. parviglobosa n. sp.), Ophiothamnus (O. biocal n. sp.) and Ophiurothamnus (O. eleaumei n. sp.). The genus Ophiocyclus is synonymised with Ophiurothamnus, Ophiomelina with Ophiacantha, Toporkovia with Ophiolimna, Ophiomytis with Ophioplinthaca, and Ophiogyptis with Ophiomoeris. Ophiomelina moniliformis (Koehler, 1904) thus becomes a junior homonym of Ophiacantha moniliformis Lütken & Mortensen, 1899 and the replacement name Ophiacantha renekoehleri n. nom. is proposed. In addition there are 37 new species-level synonymies and 19 other new genus-species combinations. A key is provided for all genera and all tropical Indo-West Pacific species of the Ophiacanthidae. The results show that the biogeographical relationship of the ophiacanthid fauna of New Caledonia is with the tropical Indo-Pacific. Less than ten percent of the fauna is shared with Southern Australia and fifteen percent with New Zealand. More broadly, there appears to be a single ophiacanthid fauna at upper to middle slope depths (200-2500 m) across the Indo-West Pacific from Africa to Hawaii, with limited east-west differentiation. This fauna grades into distinct temperate bathyal faunas near South Africa, China/Japan and Australia/New Zealand, until there is an almost complete changeover of species by 45° latitude in both hemispheres.

Résumé [+] [-]Sixty-six species of the genus Munidopsis have been studied using specimens collected during numerous French expeditions carried out in the last decades in the deep-waters of the southwest Indian and southwest Pacific Oceans, between 140 and 4400 m. Twenty-five new species are described, and the diagnoses and illustrations of some relatively rare species (M. africana, M. debilis, M. lenzii, M. moresbyi, M. orcina, M. sinclairi, M. stylirostris and M. wardeni) are provided. The reestablishment of the genus Galacantha is proposed, including the descriptions/diagnoses and a key to all species. The genus contains nine species, including three new species (G. bellis, G. diomedeae, G. quiquei n. sp., G. rostrata, G. spinosa, G. subrostrata n. sp., G. subspinosa n. sp., G. trachynotus and G. valdiviae). The number of species collected by station is very small (usually one species), probably related to their low densities. However, in some samples, as many as five species have been found. The highest number of species have been observed in the Banda Sea (Indonesia) and Solomon Islands. The new records of some species greatly extend the previously known distribution range of the species.

Résumé [+] [-]A new species of spurdog, Squalus bucephalus sp. nov., is described from deepwater south of New Caledonia in the northern Tasman Sea. It belongs to the ‘megalops-cubensis group’ but differs from Australian forms of S. megalops in having a broader head, larger dorsal-fin spines and reaches a larger adult size. It also differs in several other meristic and morphometric details and is the only Squalus known to possess both unicuspid and multicuspid denticles in adults. It is morphologically similar to the newly described S. crassispinus from the eastern Indian Ocean, but differs in having a lower, strongly raked first dorsal fin, more vertebrae, and more slender dorsal-fin spines.

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

Résumé [+] [-]The Institut de Recherche pour le Développement (IRD, formerly ORSTOM) and Muséum national d’Histoire naturelle (MNHN) launched in the early 1980s a suite of oceanographic expeditions to sample the deep-water benthos of the tropical South and West Pacific, with emphasis on the 100-1,500 m bathymetric zone. This paper reviews the development of this programme to date. It describes the procedures involved in curating the material collected and the involvement of an international network of taxonomic experts to identify, describe and name the molluscan fauna. So far, 1,028 species of molluscs have been recorded from the New Caledonia Exclusive Economic Zone from depths below 100 m, and 601 of these (58.4%) were new species. An additional 142 new species have been described from other South Pacifi c island groups (Solomon Islands, Vanuatu, Fiji, Wallis and Futuna, Tonga, Marquesas Islands and Austral Islands). However, the hyper-diverse families have essentially remained untouched. Regional differences among island groups are high, and New Caledonia, which has been sampled best, shows several discrete areas of micro-endemism. We speculate that the deep-sea mollusc fauna of New Caledonia may amount to 15-20,000 species, and the corresponding number for the whole South Pacifi c may be in the order of 20-30,000 species.
O'Hara, T. D., 2008, Bioregionalisation of the waters around Lord Howe and Norfolk Islands using brittle stars (Echinodermata: Ophiuroidea)
Résumé [+] [-]Ophiuroid assemblages were successfully predicted from current museum sample data using presence-only modeling techniques and a multivariate classification on the resulting species occurrence probabilities across the Coral and Tasman Seas (20-37°S, 148-172°E). The classification involves two-stages. The first uses a non-hierarchical clustering technique to reduce the number of data points (map-pixels) to a manageable number that can be analysed in a second stage with a hierarchical classification method. For both steps, the Bray-Curtis similarity statistic is used.

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.

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

doi: 10.3897/zookeys.18.96 Résumé [+] [-]The marine isopod family Serolidae is reviewed for the oceanic regions of the tropical and subtropical southwestern Pacific, namely from off Lord Howe Island, Norfolk Island, northern Coral Sea, New Caledonia and Fiji. Two new genera are established: Sedorolis gen. n., monotypic, from New Caledonia and Myopiarolis gen. n., a widespread Southern Hemisphere genus with 11 (eight described) species. The following new species are described: Heteroserolis pellucida (New Caledonia), Sedorolis simplex (New Caledonia), Myopiarolis koro (Fiji), M. systir (New Caledonia), M. norfanz (Lord Howe Plateau and off Norfolk Island), M. lippa (northern Coral Sea), and Thysanoserolis orbicula (New Caledonia). Keys are provided to the serolid genera and the species of Myopiarolis from the southwestern Pacifi c. Th e genus Caecoserolis Wägele, 1994 is redefined and restricted to the type species.

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

Résumé [+] [-]Two new deep water Coelorinchus species were captured during a joint Australia/New Zealand marine fauna survey of the West Norfolk and South Norfolk Ridges and south Lord Howe Rise in May-June 2003. Coelorinchus Osipullus sp. Nov. Is similar to the Australasian C. celaenostomus McMillan and Paulin and had been mistakenly identified as such in French collection surveyx off New Caledonia and the Loyalty Islands, but the new species has pale to dusky lips and mouth compared to the intense black markings of C. celaenostomus. It is also very similar to C. sheni Chiou, Shao, and Iwamoto from Taiwan, but has shorter and narrower snout and blackish gums compared to the pale gums of C. sheni. Coelorinchus obscuratus sp. Nov. Is most similar to C. occa (Goode and Bean) from the western North Atlantic, but the latter has a larger orbit, lacks a blackish orbital rim, and has much more coasely spinnulated scales.

Résumé [+] [-]A new arhynchobatid skate of the genus Notoraja is described from five specimens collected on the slopes of the Norfolk Ridge between 1195 and 1313 m depth. The new species is distinct from its sibling species from southern Australian waters, the Blue Skate (N. azurea), by its smaller size, several morphometric and meristic characters, thorn pattern and dorsal and ventral coloration.

Insights from seamounts: Are deep-sea demersal fish assemblages globally homogenous?, Marine Ecology, 31, Suppl. 1, 39-51
doi: 10.1111/j.1439-0485.2010.00384.x Résumé [+] [-]Deep-sea fishes have been poorly sampled globally, and overall knowledge of demersal fish distributions and the drivers of community composition and diversity remain limited. Here, we used nine comparable datasets with specieslevel identification of fishes from research surveys around the world to test the hypothesis that deep-sea demersal fish assemblage composition on seamounts is consistent between major oceans. Two levels of analysis were undertaken: the first combined all presence-absence data from a seamount, while a second more detailed analysis included catch weight data based on a smaller number of seamounts. Overall, there was a consistent separation of seamounts by region based on the compositions of their fish assemblages. New Zealand and SE Australian seamounts have a very similar ichthyofauna, which differs substantially from seamounts in the eastern South Pacific Ocean off Chile. In the North Atlantic, Bear Seamount appears to be distinct from all others, while seamount fish assemblages off Ireland, the Azores, and Faraday Seamount have some affinities. The Tasman Sea and New Caledonian seamounts show strong intra-regional variation. On an ocean basin scale we therefore reject the hypothesis that the composition of deep-sea demersal fish fauna is homogeneous globally. However, regional patterns of both species composition and relative abundance show some similarities between widely separated geographical locations, especially where orange roughy is a dominant species. Salinity was the main environmental factor identified in a multivariate analysis of environmental covariate data. This is likely to be a result of salinity being a key characteristic defining both Antarctic Intermediate Water and North Atlantic Deep Water, the water masses found over most seamounts examined in this study, and which may explain similarities between deep-sea fish assemblages.

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: 10.1016/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.
McFadden, Catherine S., Benayahu, Yehuda, Pante, Eric, Thoma, Jana N., Nevarez, P. Andrew, France, Scott C., 2011, DNA BARCODING: Limitations of mitochondrial gene barcoding in Octocorallia, Molecular Ecology Resources, 11, 1, 19-31
doi: 10.1111/j.1755-0998.2010.02875.x Résumé [+] [-]The widespread assumption that COI and other mitochondrial genes will be ineffective DNA barcodes for anthozoan cnidarians has not been well tested for most anthozoans other than scleractinian corals. Here we examine the limitations of mitochondrial gene barcoding in the sub-class Octocorallia, a large, diverse, and ecologically important group of anthozoans. Pairwise genetic distance values (uncorrected p) were compared for three candidate barcoding regions: the Folmer region of COI; a fragment of the octocoral-specific mitochondrial protein-coding gene, msh1; and an extended barcode of msh1 plus COI with a short, adjacent intergenic region (igr1). Intraspecific variation was <0.5%, with most species exhibiting no variation in any of the three gene regions. Interspecific divergence was also low: 18.5% of congeneric morphospecies shared identical COI barcodes, and there was no discernible barcoding gap between intra- and interspecific p values. In a case study to assess regional octocoral biodiversity, COI and msh1 barcodes each identified 70% of morphospecies. In a second case study, a nucleotide character-based analysis correctly identified 70% of species in the temperate genus Alcyonium. Although interspecific genetic distances were 2 X greater for msh1 than COI, each marker identified similar numbers of species in the two case studies, and the extended COI + igr1 + msh1 barcode more effectively discriminated sister taxa in Alcyonium. Although far from perfect for species identification, a COI + igr1 + msh1 barcode nonetheless represents a valuable addition to the depauperate set of characters available for octocoral taxonomy.
O'Hara, Timothy D., Rowden, Ashley A., Bax, Nicholas J., 2011, A Southern Hemisphere Bathyal Fauna Is Distributed in Latitudinal Bands, Current Biology, 21, 3, 226-230
doi: 10.1016/j.cub.2011.01.002 Résumé [+] [-]The large-scale spatial distribution of seafloor fauna is still poorly understood. In particular, the bathyal zone has been identified as the key depth stratum requiring further macro- ecological research [ 1 ], particularly in the Southern Hemi- sphere [ 2 ]. Here we analyze a large biological data set derived from 295 research expeditions, across an equator- to-pole sector of the Indian, Pacific, and Southern oceans, to show that the bathyal ophiuroid fauna is distributed in three broad latitudinal bands and not primarily differentiated by oceanic basins as previously assumed. Adjacent faunas form transitional ecoclines rather than biogeographical breaks. This pattern is similar to that in shallow water despite the order-of-magnitude reduction in the variability of environmental parameters at bathyal depths. A reliable biogeography is fundamental to establishing a representative network of marine reserves across the world’s oceans [1, 3].

Résumé [+] [-]Thirteen new species of Scissurellidae (Scissurella regalis n. sp., Sinezona mechanica n. sp., Sinezona platyspira n. sp., Sinezona enigmatica n. sp., Sinezona wanganellica n. sp., Satondella azonata n. sp., Satondella bicristata n. sp.), Anatomidae (Anatoma amydra n. sp., Anatoma kopua n. sp., Anatoma megascutula n. sp., Anatoma tangaroa n. sp.), and Larocheidae (Larochea spirata n. sp., Larocheopsis macrostoma n. sp.) are described, all of which occur in New Zealand waters. The greatest geographic source of new taxa is the islands and underwater features off northern New Zealand. The new shell-morphological term "sutsel" is introduced for the area between the SUTure and the SELenizone.
Séret, Bernard, Last, Peter R., 2012, New deep water skates of the genus Notoraja Ishiyama, 1958 (Rajoidei, Arhynchobatidae) from the southwest Pacific, Zoosystema, 34, 2, 319-341
doi: 10.5252/z2012n2a9 Résumé [+] [-]Four new skates of the genus Notoraja Ishiyama, 1958 are described from the rarely accessed, deep waters off New Caledonia, Vanuatu and Fiji islands, and the Norfolk Ridge. Three of these (N. alisae n. sp., N. longiventralis n. sp. and N. fijiensis n. sp.) are “velcro skates” which are characterised by their velvety dorsal and ventral surfaces, covered with fine denticles. Although similar in shape, they differ by their colour pattern, dermal armature, development of the lateral tail folds, and size of the pelvic-fin anterior lobe and nasal curtain. The description of the fourth species, Notoraja inusitata n. sp., is based on a juvenile male exhibiting some unusual features resembling those of other skate genera.
Lemaitre, Rafael, Ahyong, Shane T., Chan, Tin-Yam, Corbari, Laure, Ng, Peter K.L., 2013, The genus Paragiopagurus Lemaitre, 1996 (Crustacea, Decapoda, Anomura, Paguroidea, Parapaguridae): A worldwide review and summary, with descriptions of five new species, Mémoires du Muséum national d'Histoire naturelle, 27, 204, 311-421
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.
Aznar-Cormano, Laetitia, Brisset, J., Chan, Tin‐Yam, Corbari, Laure, Puillandre, Nicolas, Utgé, José, Zbinden, M., Zuccon, D., Samadi, S., 2015, An improved taxonomic sampling is a necessary but not sufficient condition for resolving inter-families relationships in Caridean decapods, Genetica, 143, 2, 195-205
doi: 10.1007/s10709-014-9807-0 Résumé [+] [-]During the past decade, a large number of multi-gene analyses aimed at resolving the phylogeneticrelationships within Decapoda. However relationships among families, and even among sub-families, remain poorly defined. Most analyses used an incomplete and opportunistic sampling of species, but also an incomplete and opportunistic gene selection among those available for Decapoda. Here we test in the Caridea if improving the taxonomic coverage following the hierarchical scheme of the classification, as it is currently accepted, provides a better phylogenetic resolution for the inter-families relationships. The rich collections of the Muse´um National d’Histoire Naturelle de Paris are used for sampling as far as possible at least two species of two different genera for each family or subfamily. All potential markers are tested over this sampling. For some coding genes the amplification success varies greatly among taxa and the phylogenetic signal is highly saturated. This result probably explains the taxon-heterogeneity among previously published studies. The analysis is thus restricted to the genes homogeneously amplified over the whole sampling. Thanks to the taxonomic sampling scheme the monophyly of most families is confirmed. However the genes commonly used in Decapoda appear non-adapted for clarifying inter-families relationships, which remain poorly resolved. Genome-wide analyses, like transcriptome-based exon capture facilitated by the new generation sequencing methods might provide a sounder approach to resolve deep and rapid radiations like the Caridea.
Gomon, Martin F., Struthers, CARL D., 2015, Three new species of the Indo-Pacific fish genus Hime (Aulopidae, Aulopiformes), all resembling the type species H. japonica (Günther 1877), Zootaxa, 4044, 3, 371
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.
Ho, Hsuan-Ching, McGrouther, M., 2015, A new anglerfish from eastern Australia and New Caledonia (Lophiiformes: Chaunacidae: Chaunacops), with new data and submersible observation of Chaunacops melanostomus, Journal of Fish Biology, 86, 3, 940-951
doi: 10.1111/jfb.12607 Résumé [+] [-]A new deep-sea anglerfish of the genus Chaunacops is described based on three specimens collected from eastern Australia and New Caledonia. It differs from its congeners in having fine dermal spinules, mixedwith simple and bifurcate ones, densely covering the body, four neuromasts on the pectoral series of the lateral line and a combination of other characteristics. Data for Chaunacops melanostomus based on 31 specimens newly collected from Western Australia are provided. An underwater observation of C. melanostomus made by a remotely operated vehicle is also provided.
