A new species, Psolidium kharlamenkoi n. sp. (Echinodermata: Dendrochirotida: Psolidae) is described from the Kuril Islands. The new species is distinguished from all previously described species of the genus Psolidium by combination of the external features, ossicles morphology and coloration.

A new species of the family Coryphellidae, Coryphella alexanderi sp. nov. is described based on specimens collected in the Kuril Islands, NorthWest Pacific, from the upper sublittoral to 200 m depth. An integrative analysis was conducted, including a molecular phylogenetic analysis based on four markers (COI, 16S, H3, 28S), an automatic species delimitation method ABGD, and an analysis of the external and internal morphology using light and scanning electron microcopy. The distinctiveness of Coryphella alexanderi sp. nov. is well established both morphologically and genetically, and it differs from externally similar species in radular characters. Phylogenetically Coryphella alexanderi sp. nov. is closely related to Coryphella trophina, which occurs sympatrically in the same geographic and bathymetric ranges. Coryphella alexanderi sp. nov. appears to be restricted to the middle and northern Kuril Islands, which is consistent with the high numbers of endemic taxa in this area.

Three new Clastobasis Skuse species are described: C. ainuorum sp. n. (Kuril Islands, Iturup), C. kanabo sp. n. (Japan, Honshū) and C. menguali sp. n. (Japan, Honshū). The new species are figured, photographed and their systematics discussed. New records are provided for C. loici Chandler and C. subalternans Zaitzev, both from Japan (Honshū). The number of Palaearctic Clastobasis species is set up at eight including six of them restricted only to the Eastern Palaearctic. Clastobasis loici, previously known only from Europe, is described to have a Trans-Palaearctic distribution. A key to the Palearctic species of Clastobasis is provided and the distribution shortly discussed.

Two new species of the genus Echinopsolus—E. sanamyanorum and E. onekotanensis are described. This genus is new for North-Western Pacific marine fauna. Echinopsolus sanamyanorum was collected in the Avacha Gulf (south-east coast of Kamchatka), E. onekotanensis—near the Onekotan Island (The Kuril Islands).
