Abstract: The Japanese and Taiwanese species of the genus Cladiscus Chevrolat, 1843 are reviewed. Two new species are described: C. hachijoensis sp. nov. from Japan (Hachijôjima Is.) and C. liaoi sp. nov. from Taiwan. Cladiscus pallidicornis Corporaal & van der Wiel, 1949 is recorded for the first time from Japan and C. weyersi Kraatz, 1899 from Taiwan. Cladiscus sanguinicollis (Spinola, 1844) is removed from the Taiwanese fauna, as its records are based on misidentification. The Japanese and Taiwanese members, plus C. thalassinus Murakami, 2017 from Borneo, Malaysia, are divided into two species groups based on the features of male and female genitalia.
