Schornikovoecia eugenyi gen. et sp. nov. of the benthopelagic ostracods of the subfamily Bathyconchoeciinae is established and described, based upon samples collected in the deep-sea zones near the Kurile-Kamchatka Trench and in the Sea of Okhotsk (Kurile Hollow). Most of the specimens have been found at depths over 5000 m. The new genus differs sharply from the currently known genera Bathyconchoecia, Scottoecia, Bathyconchoecetta and Septemoecia of this subfamily in numerous ways: the singular sculpture; the form and structure of the glands on the carapace; the masticatory pad on the mandible; the arming of the fifth limb. The new genus is at present monospecific. Descriptions of the new genus and its new species S. eugenyi sp. nov. are presented.

A New Species

Thylacoplethus isaevae, a new species of colonial rhizocephalans, is described from the hermit crab Pagurus trigonocheirus collected in the Sea of Okhotsk, along the coast of Sakhalin Island. The new species differs from other known species of Thylacoplethus by the presence of complex spermatogenic bodies located within the mantle and the significantly larger size of its externae.

The project ANDEEP was designed to fill gaps in the knowledge of the biodiversity of the Southern Ocean deep sea. Threeoceanographic cruises (ANDEEP I, II and III) were undertaken in 2002 and 2005 in the Atlantic Sector of the SouthernOcean. Hundreds of samples were collected from 40 stations with water depths ranging from 748 to 6,348 m. Investiga-tions were carried out on a broad range of taxa, including bacteria, meio-, macroand megafauna. Approximately 5000ostracods were collected, which included 29 specimens of Doloria (Dolorietta) subgen. nov.The subdivision of the genus Doloria Skogsberg, 1920 into two subgenera, Doloria (Doloria) and the novel subgenusDoloria (Dolorietta), is based on differences in the structures of the fifth limb, the armature of the sensory bristle on the5th segment of the antennula, and the number of bristles on the 4th endite of the sixth limb. Four new species in the newsubgenus were identified from the ANDEEP samples. The new subgenus and the four novel species are described andillustrated. Two of these new species are named Doloria (Dolorietta) antarctica sp. nov. and Doloria (Dolorietta) sextafiliformis sp. nov., but the other two species are left in open nomenclature (i.e. Doloria (Dolorietta) sp. nov. 1 and Doloria(Dolorietta) sp. nov. 2) because only juveniles were found in our material. Keys to the subgenera and species of Doloria are provided.

The present study deals with a collection of deep-sea shrimp of the pandalid genus Pandalopsis Spence Bate, 1888 from the Nemuro Strait, Hokkaido, southwestern part of the Sea of Okhotsk. Three new species are described and illustrated: Pandalopsis capillus n. sp., P. houyuu n. sp. and P. princeps n. sp. In addition, Pandalopsis glabra Kobjakova, 1936, a species endemic to the Sea of Okhotsk, is supplementary reported. Most specimens were collected from steep slopes or hard bottoms at depths greater than 400 m by commercial shrimp trap or gill nets operated by local fishermen. Differentiation of the new species is primarily based on a morphological comparison, supplemented by a preliminary genetic analysis of partial segments of the mitochondrial 16S rRNA gene. An identification key to the species of Pandalopsis is presented.

Exploration of the New England and Corner Rise Seamounts produced four new species of chrysogorgiid octocorals with the spiral iridogorgiid growth form. Three species are described as new in the genus Iridogorgia and one is described in the new genus Rhodaniridogorgia. Both genera have representatives in the Atlantic and Pacific Oceans. Iridogorgia magnispiralis sp. nov., is one of the largest octocorals encountered in the deep sea and seems to be widespread in the Atlantic.

A specimen of the pelagic polychaete Pedinosoma curtum Reibisch (Lopadorhynchidae) is described from the North-West Pacific. It differs from the Atlantic specimens of the species in longer aciculae, larger antennae as compared with palps and pigmentation of the dorsal cirri. A late larva of Pedinosoma рolaris sp. nov. is described from plankton of the Arctic Basin (depth 2000–1000 m). The distinctive characters of the new species are: podial lobes, aciculae and compound chaetae present on the tentacular segment, the absence of cirrophores of the tentacular and ventral podial cirri, the podial cirri arranged on the podial process, and a well-developed pygidium bearing anal cirri. An additional diagnosis of the genus Pedinosoma Reibisch is provided.
