Schornikovoecia eugenyi gen. et sp. nov.

Pelagic ostracods of the new subtribe Conchoeciina (Ostracoda, Crustacea) from the North Pacific.

The tribe Conchoeciini Chavtur Angel, 2011, which was singled out by Chavtur and Angel (2011) from the subfamily Conchoeciinae Müller, 1912, is divided into the new Conchoeciina subtribe, including all species of the genera Conchoecia Dana, 1849 and Porroecia (Martens, 1979), and the "non-Conchoeciina" group, which includes all the remaining genera in other subtribes. The genus Conchoecia is subdivided into five genera - retaining Conchoecia and establishing four new genera, namely Macrochoecilla Chavtur, gen. nov.

Benthic myodocopid Ostracoda (Philomedidae) from the Southern Ocean.

This study is based on the material of myodocopid ostracodes of the family Philomedidae collected by the Russian Antarctic Polar Expeditions (1963-2007) and the Germany Expeditions on R/V "Polarstern" (1990-2002) from the continental shelf and upper slope near the Mawson and Davis stations, the Weddell Seas, the region of the South Shetland Islands near the Russian Polar station "Molodezhnaya" and adjacent waters. Eight philomedid species belonging to two genera were identified in these collections. Scleroconcha tuberculata sp.

Description of new members of the family Cylindroleberididae (Ostracoda: Cylindroleberidoidea) from the Southern Ocean.

We report new ostracod data (Family Cylindroleberididae) based on material collected during the German Expeditions onboard the research vessel "Polarstern" from bathyal and abyssal zones (sampling depth range from 1030 to 3963 m) in the Weddell and Scotia Seas and Drake Passage in 2002 and 2005. Four species belonging to four genera were identified in these collections. A new species, Synasterope pseudomystax, is illustrated and described.
