Abstract

Collections of holothurians taken in 2012-2016 by three German-Russian deep-sea expeditions to the Kuril-Kamchatka Trench area (KuramBio, SokhoBio and KuramBio II) were examined. Here we present data on the genus Psychropotes (Psychropotidae, Elasipodida). Based on new material and some additional (mainly old) material from the North-West and East Pacific, we re-describe the species Psychropotes Iongicauda Theel, 1882, describe two varieties, P. longicauda var. monstrosa Theel, 1882 and P. longicauda var. fuscopurpurea Theel, 1882, as separate species, re-establish the species P. raripes Ludwig, 1893, P. dubiosa Ludwig, 1893 and P. dyscrita (Clark, 1920), and describe two new species: P. moskalevi sp. nov. and P. pawsoni sp. nov.
