Two bopyrid isopods, Metaphrixus setouchiensis sp. nov. and Bopyrina ocellata (Czerniavsky, 1868) were obtained from a caridean shrimp Hippolyte sp. collected from the Sargassum bed in the Seto Inland Sea, western Japan. Metaphrixus setouchiensis is the first record of the genus from Japan. The new species differs from its congeners in having indistinct head, the articulated antenna 1, and presence of dorsolateral bosses on the pereon. Bopyrina ocellata is redescribed using newly collected specimens.
