Cymonomid crabs are small cryptic deep-water brachyurans occurring worldwide. Six species have been reported from East Asia: one from both Taiwan and Japan (C. andamanicus Alcock, 1905) and five from Japan only (C. curvirostris Sakai, 1965, C. japonicus Balss, 1922, C. sagamiensis Sakai, 1983, C. soela Ahyong and Brown, 2003, C. umitakae Takeda, 1981). Cymonomus curvirostris, C. japonicus, C. sagamiensis and C. umitakae were described from Japanese waters, but C. andamanicus and C. soela have much more distant type localities - the Andaman Sea and southeastern Australia, respectively. We review all previous records of Cymonomus from East Asia, describe two new species, and clarify the status of records of C. andamanicus and C. soela from the region. Records of C. andamanicus and C. soela from East Asia are referable to two new species occurring in both Taiwan and Japan. The identities of C. japonicus and C. sagamiensis are fixed by neotype selection; C. sagamiensis is made a junior objective synonym of C. umitakae. Six species of Cymonomus are now recorded from Japan, of which two also occur off Taiwan. We also report on cymonomids collected by Taiwanese research vessels in the South China Sea (Dongsha and Macclesfield Bank) of which four species were collected, including C. hakuhoae Takeda and Moosa, 1990, not previously found in Japan or Taiwan. A key to the species of Cymonomus from East Asia and the South China Sea is included.

Pycnogonid material collected between August 2000 and August 2003 from Taiwanese waters at depths between 100 and 2620 m is described. The thirty-three specimens represent ten species, and include one hitherto undescribed species of each of the genera Nymphon, Colossendeis and Pycnogonum. There are no previously published records of pycnogonids from Taiwan. Nymphon polyglia sp. nov. has multiple cement gland pores on the femur and first tibia, and tarsus and propodus subequal in length. Colossendeis mycterismos sp. nov. has affinities with C. pipetta, but has a tarsus shorter than the propodus. Pycnogonum cranaobyrsa sp. nov. has a slender tapering proboscis, no auxiliary claws and pointed mid-dorsal trunk tubercles, with a pustulate integument and a rounded ocular tubercle. The cement-gland openings of Heterofragilia hirsuta are described.

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.

Fifteen species of Cancellariidae referable to the genera Zeadmete, Admetula, Fusiaphera, Nipponaphera, and Trigonostoma are reported from depths between 200 and 700 m in New Caledonia and other island groups in the southwest Pacific. Twelve are new species: Zeadmete bathyomon new species, Zeadmete physomon new species, Zeadmete bilix new species, Admetula affluens new species, Admetula marshalli new species, Admetula bathynoma new species, Admetula lutea new species, Admetula emarginata new species, Nipponaphera argo new species, Nipponaphera agastor new species, Nipponaphera tuba new species, and Trigonostoma tryblium new species. All the Recent nominal species of Fusiaphera described from localities throughout the Indo-Pacific area Lire considered to be conspecific, the senior name being Fusiaphera macrospira (Adams and Reeve, 1.850), now with ten synonyms. The ranges of Nipponaphera nodosivaricosa (Petuch, 1.979) and Trigonostoma thysthlon Petit and Harasewych, 1987, are extended to the South Pacific.

This study adds 8 bopyrids to the 5 species previously known from Taiwan. None of the species are new to science, but all are new to the Taiwanese fauna. All of the hosts for the 8 species are new. Four species redescribed herein, Pseudione retrorsa Richardson, Parioninella obovata Shiino, Parapenaeon tertium Nierstrasz and Brender 6 Brandis, and Bopyrus stebbingi Nierstrasz and Brender Brandis, are reported for the 1st time since their original descriptions, with each representing a substantial range extension. The geographic and depth distributions of 2 additional species, Bopyroides hippolytes (Kroyer) and Athelges takanoshimensis Ishii, are greatly extended. Two new genera are erected for P. obovata and B. stebbingi. Pseudione lenticeps Shiino is synonymized with P. retrorsa, which is transferred to the genus Aporobopyrus Nobili. Parapenaeon coarctatum tuberculata is raised to the level of full species. Identifications of hosts as cited in older literature are updated to current nomenclature.

During the recent Taiwan TAIWAN and the Philippines PANGLAO 2005 and AURORA deep-sea expeditions, many specimens of nematocarcinid shrimp were collected. Altogether three genera and 13 species are identified: Nigmatullinus acanthitelsonis (Pequegnat, 1970), Segonzackomaius altus (Bate, 1888), Nematocarcinus chacei Burukovsky, 2002, N. combensis Burukovsky, 2000, N. crosnieri Burukovsky, 2000, N. gracilis Bate, 1888, N. productus Bate, 1888, N. rectirostris Burukovsky, 1991, N. richeri Burukovsky, 2000, N. subtegulisfactus Burukovsky, 2000, N. subtilis Burukovsky, 2000, N. tenuipes Bate, 1888 and N. tenuirostris Bate, 1888. Amongst them, S. altus, N. chacei and N. crosnieri are the second records since their original descriptions. Moreover, two genera and 11 species are new records for Taiwan while two species are new Philippine records. Diagnoses for the family, subfamilies, and genera and a key to all species of Nematocarcinus A. Milne-Edwards, 1881 are given. Colour photographs of 10 species are also provided. The studied area was subdivided into northern and southern subareas. The northern area includes the waters around Taiwan (21°18’-25°22’N and 117°17’-123°01’E), and the southern area the waters of the Philippines (08°33’-16°06’N and 121°30’-124°10’E). Five species occur in both subareas. A comparison of the present data with the known data on the nematocarcinid shrimp fauna of the Indo-Malay area or East Indies Triangle (i.e. the centre of species diversity of shrimps of family Nematocarcinidae) revealed that the area between Taiwan and the northern Philippines is an ecotone, with a transitional nematocarcinid shrimp fauna between the fauna of the East Indies Triangle and the typical Indo-West-Pacific fauna.

A reappraisal of the taxonomy of the brachyuran crabs belonging to the family Goneplacidae MacLeay, 1838 sensu lato has resulted in the revision of the subfamily Goneplacinae, which combines the subfamilies Goneplacinae MacLeay, 1838 and Carcinoplacinae H. Milne Edwards, 1852. Most of the 66 species of Goneplacinae sensu stricto that are listed herein inhabit relatively deep water and are infrequently collected. The subfamily Goneplacinae sensu stricto now consists of 17 genera of which 10 are being described as new: Carcinoplax H. Milne Edwards, 1852, with 18 species of which four are new; Entricoplax n. gen., monotypic; Exopheticus n. gen., with two species; Goneplacoides n. gen., monotypic; Goneplax Leach, 1814, with four species; Hadroplax n. gen., monotypic; Menoplax n. gen., monotypic; Microgoneplax n. gen., with five species of which four are new; Neogoneplax n. gen., with three species of which two are new; Neommatocarcinus Takeda & Miyake, 1969, monotypic; Notonyx A. Milne-Edwards, 1873, with three species; Ommatocarcinus White, 1852, with four species; Paragoneplax n. gen., monotypic; Psopheticus Wood-Mason, 1892, with four species; Pycnoplax n. gen., with five species of which one is new; Singhaplax Serene & Soh, 1976, with seven species of which four are new; and Thyraplax n. gen., with five species of which three are new. All goneplacine genera are exclusive to the Indo-West Pacific region (plus contiguous temperate areas) except Goneplax, which is so far known mostly from the Atlantic and Mediterranean regions. Four nominal species described by other authors were found to be junior subjective synonyms for other species: Carcinoplax verdensis Rathbun, 1914 and C polita Guinot, 1989 synonymous of C specularis Rathbun, 1914; Goneplax megalops Komatsu & Takeda, 2003 of Goneplacoides marivenae (Komatsu & Takeda, 2003) n. comb.; and Psopheticus insolitus Guinot, 1990 of P stridulans Wood-Mason, 1892.

A new shrimp species of the genus Plesionika Bate, 1888 is described based on specimens collected in deep-water off eastern Taiwan. The new species, P. albocristata, can be readily distinguished from other species of the genus by bearing a high basal rostral crest, having the second pereiopods subequal, and the telson bearing four pairs of dorsolateral spines. A brief discussion on the affinities of this new species is given.

TAIWAN 2000

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.

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.

Seven shrimp species of the family Stylodactylidae are reported here from Taiwanese waters, four of which represent new records for the area. Only three species of this family were previously known from Taiwan: Stylodactylus in multidentatus Kubo, 1942, and Parastylodactylus bimaxillaris (Bate, 1888), both present in the collection studied here, and Bathystylodactylus inflatus Hanamura & Takeda, 1996, no material in the present collection. Stylodactylus major Hayashi & Miyake, 1968, is recorded for the second time. The other species are: Stylodactylus libratus Chace, 1983, Stylodactylus licinus Chace, 1983, and Stylodactylus tokarensis Zarenkov, 1968. On another hand, the status of a seventh species, related to Stylodactylus pubescens Burukovsky 1990, is left unresolved. The rare deep-sea shrimp family Bathypalaemonellidae is added to the Taiwanese decapod fauna, being represented by four species, one of which is new: Bathypalaemonella hayashii Komai, 1995; Bathypalaemonetes brevirostris (Bruce, 1986); Bathypalaemonetes pilosipes (Bruce, 1986) and Bathypalaemonetes chani, new species.

Species of the bivalve family Lucinidae form a previously unrecognized and signifi cant component of bivalve assemblages at bathyal depths (150-1000 m) in the Indo-West Pacifi c province. Elliptiolucina labeyriei n. gen., n. sp., from 2570 m, is the deepest-occurring lucinid species. South-East Asian seas, from Taiwan to the Arafura Sea, are a hotspot of deep-water lucinid diversity, with 11 species recorded from the Philippines and 14 from Indonesia. Numerous species are in the 20-50 mm range, with several up to 75-80 mm in size, and Meganodontia acetabulum reaches 150 mm. Several species co-occur with representatives of the Vesicomyidae, characteristic of seep and vent communities. It is hypothesized that the lucinid species of this radiation live in discrete pockets of poorly oxygenated sediments enriched in sulfi de by plant debris from nearby land masses and/or diffuse seeping. A parallel is drawn with the “Calcari a Lucina” from the Miocene of Europe. Nine new genera and 32 new species are described.

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.

This work deals with 31 species of Sicyonia H. Milne Edwards, 1830, based on the collections made by the IRD (ex ORSTOM) and the Museum national d'Histoire naturelle, Paris, and on the collections of 28 other museums. Nineteen species are considered valid: S. australiensis Hanamura Wadley, 1998; S. benthophila de Man, 1907; S. bispinosa de Haan, 1850; S. curvirostris Balss, 1913; S. fallax de Man, 1907; S. furcata Miers, 1878; S. inflexa (Kubo, 1949); S. japonica Balss, 1914; S. laevis Bate, 1881; S. lancifer (Olivier, 1811); S. longicauda Rathbun, 1906; S. nasica Burukovsky, 1990; S. ocellata Stimpson, 1860; S. parafallax Crosnier, 1995; S. parvula de Haan, 1850; S. rectirostris de Man, 1907; S. trispinosa de Man, 1907; S. truncata (Kubo, 1949) and S. vitulans (Kubo, 1949). Four species are considered to be synonyms: S. cristata (de Haan, 1844) = S. lancifer; S. formosa (Chan & Yu, 1985) = S. furcata; S. ommanneyi Hall, 1961 = S. ocellata; S. nebulosa Kubo, 1949 = S. laevis. Twelve species are described as new: S. abathophila n. sp., S. adunca n. sp., S. altirostrum n. sp., S. dejouanneti n. sp., S. komai n. sp., S. longicornis n. sp., S. metavitulans n. sp., S. parajaponica n. sp., S. robusta n. sp., S. rocroi n. sp., S. rotunda n. sp. and S. taiwanesis n. sp. Some forms, near S. australiensis and S. dejouanneti n. sp., are mentioned but not named because the material available is insufficient. An attempt is made to classify the Indo-West Pacific species of Sicyonia into eight groups. Some groups are coherent, while others are certainly artificial. Some species cannot be placed in any of the groups and the placement of several species known from one sex only remains hazardous. An identification key is presented. Particular care was taken in illustrating the genitalia, which provide the most important characters for recognizing the species. Colour photographs show the coloration of living specimens of 17 species. Depth zones and geographic distributions of all the species are presented in tabular form. As with previous studies, high species diversity of the Philippines-Indonesia fauna is evident, as well as the reduction of the number of species when one moves away from the area, except for New Caledonian area because of the unusually high h density of the samples collected in this area.

The second part of the series deals with the dredged Triviidae from Taiwan. The Triviid fauna of Taiwan is still fragmentarily known. It resembles the one of the Philippines but the deep sea fauna is still different although both are in direct neighborhood. Hereinafter one Novatrivia and five Gregoia are described as new - Novatrivia taiwanica n. sp., Gregoia yurikantori n. sp., Gregoia danielleae n. sp., Gregoia formosa n. sp., Gregoia vorago n. sp. and Gregoia aemula n. sp. These taxa could not be detected in the Philippines so far although dredgings in deep water are regularly done in the Philippines and the author could examine thousands of specimens in several collections..

The radula of Manaria inflata Shikama, 1971 is studied and found to differ from bot Manaria Smith, 1906 and Eosipho Thiele, 1929. The new genus Phaenomenella gen. nov. is described to accommodate this species and Aulacofucus insulapratasensis Okutani & Lan, 1994. Another species with identical radula, but different in sculpture and shape is described as Phaenomenella augusta sp. nov.

In the present paper we describe the new genus Amiantofusus gen. nov. to accommodate the Atlantic species Fusus amiantus Dall, 1889. The genus belongs to Fasciolariidae and this family is confirmed as distinct from Buccinidae, based on anatomical differences. We add an Indo-West Pacific fauna of seven species described as new to science: miantofusus pacificus sp. nov. (North Fiji Basin, New Caledonia, southern Coral Sea, south West Pacific), A. gloriabundus sp. nov. (North Fiji Basin, Vitiaz Zone), A. sebalis sp. nov. (New Caledonia, Loyalty Islands, Vanuatu), A. candoris sp. nov. (Chesterfield Islands, Fairway), A. maestratii sp. nov. (New Caledonia), A. borbonica sp. nov. (Reunion) and A. cartilago sp. nov. (Mozambique Channel). In addition we add two unnamed species: A. species 1 (North Fiji Basin) and A. species 2 (Vanuatu). Fusus thielei Schepman, 1911 is briefly discussed, the generic placement is still uncertain.

The genus Phaenomenella is briefly reviewed. Phaenomenella vexabilis sp. nov. is described from deep-water off Taiwan. It is compared with P. mokenorum Fraussen, 2008 and P. inflata (Shikama, 1971). The shell shape and the spiral sculpture serve to distinguish the single known broken shell from all other known Phaenomenella species.

While the taxonomic details at the generic level were discussed by Kantor et al. (2013), the species level is discussed here. Twentyone new species are described: Manaria astrolabis n. sp. (French Polynesia), M. borbonica n. sp. (Réunion), M. circumsonaxa n. sp. (Papua New Guinea and the Solomons), M. corindoni n. sp. (Indonesia), M. corporosis n. sp. (the Solomons, Vanuatu, Coral Sea and New Caledonia), M. explicibilis n. sp. (Papua New Guinea and the Solomons), M. excalibur n. sp. (Indonesia and Western Australia), M. fluentisona n. sp. (the Solomons, Fiji, Wallis and Tonga), M. hadorni n. sp. (Papua New Guinea and New Caledonia), M. indomaris n. sp. (India), M. loculosa n. sp. (Fiji), M. lozoueti n. sp. (North Fiji Basin), M. terryni n. sp. (Mozambique Channel), M. tongaensis n. sp. (Tonga), M. tyrotarichoides n. sp. (Mozambique Channel), Calagrassor bacciballus n. sp. (Philippines), C. delicatus n. sp. (New Zealand), C. hespericus n. sp. (Mozambique), C. pidginoides n. sp. (Philippines, Papua New Guinea, the Solomons and Vanuatu), Enigmaticolus marshalli n. sp. (Kermadec Ridge, Monowai Caldera), and E. voluptarius n. sp. (New Caledonia). Considerable range extensions are recorded: Manaria kuroharai Azuma, 1960 is recorded from the Solomons, New Caledonia, Vanuatu and Tonga; M. brevicaudata (Schepman, 1911) is recorded from Taiwan, the Philippines, the Solomons and Fiji; and Calagrassor poppei (Fraussen, 2001) is recorded from Indonesia and the Solomons. Lathyrus jonkeri Koperberg, 1931, a fossil described from Indonesia, is recorded from the Recent fauna of Indonesia, Philippines and Fiji and is redescribed and placed in Manaria. Sipho jonkeri Koperberg, 1931, another fossil described from Indonesia in the same work, is a secondary homonym of Manaria jonkeri (Koperberg, 1931) and is renamed Manaria koperbergae nom. nov.

Two new species of the genus Calagrassor Kantor et al., 2013 are described. Calagrassor analogus n. sp. is distributed in Japan, the East China Sea and Taiwan, and has been previously confused with Aulacofusus hiranoi (Shikama, 1962). Differences in protoconch morphology serve to distinguish C. analogus n. sp. from A. hiranoi and differences in sculpture serve to distinguish this new species from C. aldermenensis (Powell, 1971) and C. hayashii (Shikama, 1971). A second and hitherto unknown species is described from Japanese waters as Calagrassor hagai n. sp. Differences in spiral and axial sculpture serve to distinguish it from other known species in the genus.

Forty-three species of sertulariid hydroids (Cnidaria: Hydrozoa: Sertulariidae), collected from the tropical western Pacific (Taiwan, Philippines, New Caledonia, French Polynesia, Vanuatu, Fiji, Tonga, Solomon Islands) during various expeditions of the French Tropical Deep-Sea Benthos program, are discussed. Of these, nine are new to science: Gonaxia nova sp. nov., G. plumularioides sp. nov., Sertularella folliformis sp. nov., Se. plicata sp. nov., Se. pseudocatena sp. nov., Se. splendida sp. nov., Se. tronconica sp. nov., Se. tubulosa sp. nov., and Symplectoscyphus paucicatillus sp. nov. The subspecies Symplectoscyphus johnstoni (Gray, 1843) tropicus Vervoort, 1993 is raised to species but, in order to avoid the secondary homonymy with Sy. tropicus (Hartlaub, 1901), the replacement name, Sy. fasciculatus nom. nov., is introduced. The male and female gonothecae of Diphasia cristata Billard, 1920, the male gonothecae of Gonaxia elegans Vervoort, 1993, as well as the female gonothecae of Salacia macer Vervoort & Watson, 2003, are described for the first time. Additional notes on the morphology of several other species are provided. All taxa are illustrated, in most cases using figures drawn at the same scale, so as to highlight the differences between related species.

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.

The subgenus Dermomurex (Takia) is reviewed and one new species, D. (T.) manonae n. sp., is described from New Caledonia. It is distinguished from the similar D. (T.) wareni Houart, 1990 based on genetic differences and a few shell characters. From other species it differs in its shell and intritacalx morphology. The four Indo-West Pacific species are reviewed and illustrated, namely D. (T.) bobyini Kosuge, 1984, D. (T.) infrons Vokes, 1974, D. (T.) wareni Houart, 1990 and D. (T.) manonae n. sp. Dermomurex (subgenus?) paulinae n. sp. is described from New Caledonia in an undetermined subgenus and is distinguished from D. (D.) africanus Vokes, 1978 from South Africa by its shell and intritacalx morphology. Trialatella is synonymized with Dermomurex s.s.

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.

The bathypelagic shrimp genus Pasiphaea Savigny, 1816 (Caridea: Pasiphaeidae) has been previously known from Taiwan from only three species. However, recent deep-sea surveys around the island have collected numerous specimens comprising ten species, of which four are new to science: P. aeons n. sp., P alcocki (Wood-Mason and Alcock, 1891), P exilimanus n. sp., P. falx n. sp., P japonica Omori, 1976, P. mclaughlinae Hayashi, 2006, P levicarinata Hanamura, 1994, P orientalis Schmitt, 1931, P. sirenkoi Burukovsky, 1987 and P. taiwanica n. sp. The four new species are fully described and illustrated, and compared with allied congeners. Pasiphaea orientalis is redescribed, as this species is endemic to Taiwan and its original description is inadequate. Amongst the three new records of Taiwan, P. levicarinata is also recorded for the first time from the northwestern Pacific.

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

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

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.

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.

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

A new genus and species of pontoniine shrimp, Patonia mclaughlinae n. gen., n. sp., is described and illustrated based on a single ovigerous female collectedat depths of 209 to 280 m, during a recent deep-sea expedition off Taiwan. This new genus differs from other Pontoniinae genera in a combination of characters: hepatic spine bearing a complete basal suture and possibly mobile, body laterally compressed, rostrum distinctly dentate along entire dorsal margin and unarmed ventrally, basal antennular segment tridentate distolaterally, and second pereiopod very slender with carpus much longer than chela.

Based on material stored in Museum National d'Histoire Naturelle (MNHN) eight new species collected from bathyal depths in South West Pacific archipelagos ( Solomon Islands and Fiji) are described. The new species belong to the rather poorly known genera Acanthodaphne Bonfitto et Morassi, 2006, Acamptodaphne Shuto, 1971, Buccinaria Kittl, 1887, Cryptodaphne Powell, 1942 and Mioawateria Vella, 1954 all belonging to subfamily Raphitominae Bellardi, 1875 in the family Conidae Fleming, 1822. Acamptodaphne eridmata sp. nov. has a broad distribution being reported from the Solomon Islands and Taiwan. Finding of the new species here discussed in South West Pacific archipelagos provides a significant extension to the previously known geographical range of these raphitomine genera.

Squat lobsters of the family Munidopsidae are reported from deep-waters off the Philippines based on the material collected by the PANGLAO 2005 and AURORA expeditions. The material includes three species of the genus Galacantha A. Milne-Edwards, 1880 and 23 species of Munidopsis Whiteaves, 1874. Four species are described as new to science and nine species are recorded for the first time from the Philippines. Colour notes and illustrations from fresh specimens are provided for all the species. The poorly known species, Munidopsis ceratophthalma Alcock, 1901, is described in detail based on a Philippine specimen to supplement the original account of the species. Re-examination of the specimen previously reported as M. ceratophthalma from Taiwan reveals that it represents a new species, which is hereby described in this report.

Brachyuran crabs belonging to the subfamily Ethusinae Guinot, 1977, family Dorippidae MacLeay, 1838, are adapted to carry bivalve shells or other objects on their backs by using the hooked dactyli of their last two pairs of pereopods (P4 and P5), which are dorsally located and mobile. Most species inhabit deep water and are infrequently collected. The taxonomy of the 57 known Indo-West Pacific species of ethusines is revised. The subfamily consists of three genera: Ethusa Roux, 1830, with 30 species of which four are being described as new, Ethusina Smith, 1884, with 25 species of which eight are new, and Parethusa Chen, 1997, with two species of which one is new. Ethusa and Ethusina are worldwide in distribution while Parethusa is exclusive to the Indo-West Pacific region. Seven nominal species described by other authors were found to be junior subjective synonyms of other species: Ethusa major Chen, 1993, of Ethusa orientalis Miers, 1886; Ethusa makasarica Chen, 1993, of Ethusa hirsuta McArdle, 1900; Ethusa madagascariensis Chen, 1987, of Ethusa zurstrasseni Doflein, 1904; Ethusina investigatoris (Alcock, 1896) and E. alcocki Ng & Ho, 2003, of Ethusina robusta Miers, 1886; Ethusina insolita Ng & Ho, 2003, of Ethusina dilobotus Chen, 1993; and Ethusina saltator Ng & Ho, 2000, of Ethusina paralongipes Chen, 1993.

On the basis of fresh collections from various parts of the western Pacific, three species of majoid crabs previously considered as rare are redescribed and figured: Oxypleurodon bidens (Sakai, 1969), O. auritum (Rathbun, 1916) and O. coralliophilum (Takeda, 1980). Four new species are described: O. boholense from the Philippines, O. barazeri and O. parallelum front the Solomon Islands, and O. alaini from New Caledonia. A new genus and new species, Stegopleurodon planirostrum, is described from New Caledonia and Vanuatu. The two species currently assigned to the allied American genus Sphenocarcinus A. Milne-Edwards, 1875, are re-examined, and a new genus, Rhinocarcinus. is established for the Pacific species Sphenocarcinus agassizi Rathbun, 1893.

Members of the family Coralliidae, known as precious corals, are ecologically and economically important deep sea organisms. However, these organisms are currently threatened by commercial harvesting. In order to create and implement effective conservative strategies, taxonomic knowledge of conservative targets is necessary, but unfortunately the taxonomy of precious corals in this family is still ambiguous. This study provides a review of 15 Coralliidae species from the northern West Pacific region and a key to species identification. In addition, descriptions of two new species, Corallium carusrubrum n. sp. and C. taiwanicum n. sp., as well as a redescription of C. sulcatum Kishinouye, 1903 are included. Corallium carusrubrum n. sp. is distributed on seamounts off northeastern Taiwan. The autozooids of C. carusrubrum n. sp. are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is short and cylindrical rather than typically hemispherical; additionally, there are no long spindles in their tentacles. Corallium taiwanicum n. sp. is distributed in an area off southwestern Taiwan. It has special unique 8-radiates with an oval shape and large projections. Corallium sulcatum is distributed from an area off southwestern Taiwan to western Japan. It has been harvested and traded for decades, but there were no illustrations in its original description, hence a redescription of this species is provided.

Before talking about a largely underestimated and poorly known, yet so beautiful family of Gastropoda, there is an issue which I must attract your attention to. While gathering the necessary information, shells and literature, I often wondered why people still call some of the Tonnidae by the wrong name, despite the sometimes meticulous research done by scientists in the past. Is it because of the often controversial information in the available publications? Is it for lack of decent information? This issue became clear to me when I was looking into the most recent publications on Eudolium such as Piani (1977), Marshall (1992) and Bouchet & Waren (1993). All concluded that what is usually sold as Eudolium pyriforme is in fact Monterosato 's true Eudolium crosseanum. I must say I was a bit shocked to read those papers and see some photographs of the type material. Why were erroneous names still used ifproofwas there, clearly and undoubtedly, to the contrary? It took me a few weeks and a few discussions with Dr Philippe Bouchet and Dr Alan Beu to figure it out, but in the end, the answer is simple: In scientific terms, proof is given by photography and description, and maybe by discussion, but not in such words or language that they are understandable to the untrained reader. Also, such research is often documented in broader publications (e.g. Bouchet & Waren, 1993; Beu, 2005) that don't attract the attention of the advanced amateur or naturalist straight away, and are wrongfully neglected. These works are seldom offered commercially, and thus unjustly remain unknown to the wider public. It is in this respect that works such as the Concho logical Iconography, often written by advanced naturalists, have their true value and Guido Poppe, Klaus Groh and Yves Terryn must be commended for an initiative such as this is an excellent medium to bring science and amateur collecting closer together in an attempt to cover the gap between the two. It is my ambition to give a synoptical overview ofthe existing (described) species, based on my collection of well over 1000 specimens and an ever-increasing library of historical as well as recent publications. Ten years of collecting and studying shells and publications have resulted in what is to follow. I have listed the most important synonyms for each species in order to clarify some of the dubious issues, but the lists are not exhaustive. Although I have many of the old publications through digital photography, I'm sure that there are still many more out there. And even if I was to spend another month in the libraries of, e.g. the BM(NH) or the MNHN, there will still be publications "hidden" somewhere. I mainly concentrate my research on Recent material, whilst a lot has been described in the fossil area as well. For example: recently, Dr Alan Beu discovered that there is an earlier name for what we all know as Eudolium pyriforme (G. B. Sowerby III, 1914), namely Eudolium javanum (Martin, 1879), originally described as the fossil Cassidariajavana from the late Miocene oflndonesia. While researching this, he also discovered names such as Dolhun hochstetteri Martin, 1879 (= Tonna allium (Dillwyn, 1817)) just to give one example. Another issue is interpretation. Many have interpreted, e.g. Adanson's "Le Minjac" in different ways. For one author, it is T. marginata (Philippi, 1845), for another author T. tessellata (Lamarck, 1816). March (1852) even lists it as a full species, D. minjac. In order to clarify such matters, I have tried to compare specimens with type material. This publication should be a solid basis for any future researcher in this family and I do hope you will all find the necessary answers to your basic tun-related questions to start that collection you always wanted to start.

The availability of fresh specimens of the commercial, deep-sea pandalid shrimp, Heterocarpus woodmasoni Alcock, 1901, from India revealed that material referred to this species from India and the western Pacific Ocean have distinct differences in coloration, morphology, and genetic divergence. Although the syntypes of H. woodmasoni cannot be located now, a color photograph of a typotypic specimen from the Andaman Sea allowed the determination of the Indian form as the true H. woodmasoni. To stabilize the taxonomy in the “H. woodmasoni” species group, a neotype is selected for H. woodmasoni from an Indian specimen with both coloration and molecular barcoding information. The western Pacific form is described as a new species, Heterocarpus fascirostratus sp. nov., which differs from H. woodmasoni in having a banded rostrum, eggs reddish brown instead of greenish brown, lacking rostral crest, armed usually with fewer dorsolateral spines on the telson, the overhanging spine on the abdominal somite III not markedly recurved downwards, and a rather straight postantennal carina.
