Two new rare chitons of the genus Stenosemus (Mollusca: Polyplacophora: Ischnochitonidae)

B.I. Sirenko

Abstract. Two new species of chitons, Stenosemus moskalevi sp. nov. from the Bering Sea (northwestern Pacific Ocean) and S. merweae sp. nov. from the coastal waters of South Africa (southeastern Atlantic Ocean) are described in this paper: S. moskalevi sp. nov. is distinguishable from other congeneric species by its structures of tegmentum and dorsal spicules; S. merweae sp. nov. differs from many other species of the genus by having many-colored tegmentum and girdle and the structure of dorsal spicules.
