Echinodermata North-Western Pacific Avacha Gulf Onekotan Island holothurians new species Holothuroidea Dendrochirotida Cucumariidae Echinopsolus sanamyanorum Echinopsolus onekotanensis


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).
