| A taxonomic review of the two genera of the family Alvinocarididae (Decapoda: Caridea), Rimicaris Williams and Rona, 1986 and Chorocaris Martin and Hessler 1990, is presented based on study of type materials and/or supplemental material from recent collections. Two species of Rimicaris, R. exoculata Williams and Rona 1986 and R. kairei Watabe and Hashimoto 2002, and three species of Chorocaris, C. chacei Williams and Rona 1986, C. vandoverae Martin and Hessler 1990, and C. paulexa Martin and Shank 2005, are recognized. All species are exclusively associated with deep-water hydrothermal community. Close relationship between the two genera is confirmed by morphological characters, but the monophyly of Chorocaris is not corroborated. An examination of a good... |

| 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... |

| Nautilocaris saintlaurentae gen. nov, sp. nov, is described and illustrated from hydrothermal vents in the North Fiji Basin and Lau Basin in the south-western Pacific. This new taxon is assigned to the Alvinocarididae. It has a well-developed, dorsally dentate rostrum, carapace with pterygostomian spine present, eye broadly fused mesially, epipod-setobranch complex present above pereopods, and appendix internae on second to fourth pleopods greatly reduced. This combination of characters places it in an intermediate position between a group of species in the genus Alvinocaris with well developed, dorsally, dentate rostrum, carapace with pterygostomian spine present, eyes narrowly fused mesially, epipod-setobranch complex absent and well-developed appendices... |

| 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... |
