An account of the Ischnomesidae (Peracarida, Isopoda) from the Kuril–Kamchatka Trench and abyssal plain (Northwest Pacific) with the description of two new species
During the German–Russian expedition KuramBio (Kuril–Kamchatka Biodiversity Studies) from board of the RV Sonne to the Kuril–Kamchatka Trench and adjacent abyssal plain, benthic samples were taken by means of a camera-epibenthic sledge. Amongst one of the most diverse macrobenthic taxa, the Isopoda...

Amongst one of the most diverse macrobenthic taxa, the Isopoda (Crustacea, Malacostraca), Ischnomesidae were the fifth most abundant isopod family in the Kuril–Kamchatka area and were sampled with 24 species from 5 genera in 21 hauls at 12 stations.
