Bouchet P., Héros V., Lozouet P. & Maestrati P. 2008. A quarter-century of deep-sea malacological exploration in the South and West Pacific: Where do we stand? How far to go?, in Héros V., Cowie R.H. & Bouchet P.(Eds), Tropical Deep-Sea Benthos 25. Mémoires du Muséum national d'Histoire naturelle 196:9-40, ISBN:978-2-85653-614-8
Résumé [+] [-]The Institut de Recherche pour le Développement (IRD, formerly ORSTOM) and Muséum national d’Histoire naturelle (MNHN) launched in the early 1980s a suite of oceanographic expeditions to sample the deep-water benthos of the tropical South and West Pacific, with emphasis on the 100-1,500 m bathymetric zone. This paper reviews the development of this programme to date. It describes the procedures involved in curating the material collected and the involvement of an international network of taxonomic experts to identify, describe and name the molluscan fauna. So far, 1,028 species of molluscs have been recorded from the New Caledonia Exclusive Economic Zone from depths below 100 m, and 601 of these (58.4%) were new species. An additional 142 new species have been described from other South Pacifi c island groups (Solomon Islands, Vanuatu, Fiji, Wallis and Futuna, Tonga, Marquesas Islands and Austral Islands). However, the hyper-diverse families have essentially remained untouched. Regional differences among island groups are high, and New Caledonia, which has been sampled best, shows several discrete areas of micro-endemism. We speculate that the deep-sea mollusc fauna of New Caledonia may amount to 15-20,000 species, and the corresponding number for the whole South Pacifi c may be in the order of 20-30,000 species.

Résumé [+] [-]The French MUSORSTOM expeditions (now Tropical Deep-Sea Benthos), have successfully collected since 1976 rich samples of large, benthic crustaceans using oceanographic vessels to depths of about 5,000 m. The ship-based collecting techniques and gear used by these expeditions are described. These include the use of echosounders, dredging, trawling, and trapping. Also discussed are techniques for onboard specimen sorting and photography.

Lemaitre R., Rahayu D.L. & Komai T. 2018. A revision of “blanket-hermit crabs” of the genus Paguropsis Henderson, 1888, with the description of a new genus and five new species (Crustacea, Anomura, Diogenidae). ZooKeys 752: 17-97. DOI:10.3897/zookeys.752.23712
Résumé [+] [-]For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis. The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica, proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n., is justified. As result, the genus Paguropsis is found to contain five species: P. typica, P. andersoni, P. confusa sp. n., P. gigas sp. n., and P. lacinia sp. n. Herein, Paguropsina gen. n., is proposed and diagnosed for two new species, P. pistillata gen. et sp. n., and P. inermis gen. et sp. n.; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species of Paguropsis, and another with the two species Paguropsina gen. n.
