The species is mostly morphologically similar to Leonardsaxius spinulicauda (Rathbun, 1902) known from Pacific(More)
Two new genera of crinoid-associated pontoniine shrimps, Brucecaris, new genus, and Unguicaris, new genus, are described and illustrated. Brucecaris is established for Periclimenes tenuis Bruce.

The hermit crab Pagurus parvispina Komai, 1997 (Decapoda: Paguridae) was found in Vostok Bay (Peter the Great Bay, Sea of Japan) at a depth of 50–65 m. Earlier, this species was recorded from the type locality in northern Japan at a depth of 150–200 m. The finding of P. parvispina in Vostok Bay is its first record in Russian waters and substantially expands(More)
The holotype of Clibanarius sachalinicus Kobjakova, 1955 and Clibanarius hirsutimanus Kobjakova, 1971 in the collection of Zoological Institute of Russian Academy of Sciences (Saint-Petersburg, Russia) are examined.

The Japanese shore crab that occurs along the mainland Russian coast of the Sea of Japan, which was formerly defined as Hemigrapsus penicillatus (de Haan, 1835), should be attributed as Hemigrapsus takanoi Asakura et Watanabe, 2005. This conclusion is based on the study of material from the Peter the Great Bay. We discuss the range and ecology of both(More)
The new pontoniine shrimp genus, Echinopericlimenes gen. nov., is suggested for four species, Periclimenes hertwigi Balss, 1913, Periclimenes dentidactylus Bruce, 1984, Periclimenes calcaratus Chace & Bruce, 1993 and Echinopericlimenes aurorae sp. nov., belonging to so-called "Periclimenes hertwigi Balss, 1913" species group sensu stricto.

Alpheus echiurophilus sp. nov. (Crustacea: Decapoda: Caridea: Alpheidae) is described based on material from Japan (Ryukyu Islands) and Vietnam (Nha Trang Bay); an additional, morphologically slightly different specimen from Madagascar (Nosy-Bé) is preliminarily referred to A. cf. echiurophilus sp. nov., awaiting collection of additional material and/or(More)
