Abstract
Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.
