Description of Baeonectes brandtae sp. nov. and redescription of Eurycope spinifrons Gurjanova, 1933 (Crustacea, Isopoda, Munnopsidae) from the deep-sea basin of the Sea of Japan

A small collection of isopods of the family Munnopsidae Lilljeborg, 1864, including four species from the slope and the deep-sea basin of the Sea of Japan (Northwest Pacific), was studied. The new species Baeonectes brandtae sp. nov. which occurs at depths of 455–1525 m is described. It is the second species of Baeonectes Wilson, 1982 described from the Sea of Japan and the deepest recorded species of the genus. Eurycope spinifrons Gurjanova, 1933, the only Eurycope species known from the Sea of Japan is redescribed. It is the most abundant species in the studied deep-sea macrobenthic communities in all samples.
