We revised the previous records of Clorida japonica Manning, 1978 and conducted extensive field and museum material surveys in Japan. The material examined included five species of the genus Clorida Eydoux & Souleyet, 1842 as follows: C. japonica; C. albolitura Ahyong & Naiyanetr, 2000; C. denticauda (Chhapgar & Sane, 1967); C. rotundicauda (Miers, 1880); and C. seversi Moosa, 1973. Among them, C. albolitura, C. denticauda, C. rotundicauda, and C. seversi are new to the Japanese stomatopod fauna. Re-examination of the Japanese specimens previously reported as C. japonica has shown that they partially belong to Cloridina ichneumon (Fabricius, 1798), a new record from Japan as well. A key to the Japanese species of Clorida and Cloridina reported in this study is also provided.
