Abstract

Two new species of rotifer belonging to the Dicranophoridae, and provisionally placed in the genus Encentrum, are described from littoral psammon from the Ussuriyskiy Bay, Peter the Great Bay, Sea of Japan, Russia. Encentrumkutikovae sp. nov. is characterized by a long foot consisting of three pseudosegments, cylindrical toes, a hexagonal rami outline, and the right ramus showing an accessory chamber with alula. Encentrum ussuriensis sp. nov. is characterized by unusual stout toes with claw, an oblong-ovate and latero-caudal weakly angular rami outline, the right ramus bearing an alula, and the left one showing an accessory chamber.
