Taxonomic study of the genus Anterhynchium from the Eastern Asia is carried out. A total of 15 forms included in four species were reviewed: A. melanopterum, A. flavopunctatum flavopunctatum, A. flavopuntatum opulentum, A. yunnanensis, A. flavomarginatum flavomarginatum, A. f. koreanum, A. f. tsushimarum, A. f. umenoi, A. f. micado, A. f. procella, A. f. insulicola, A. f. sulphreum, A. f. amamense, A. f. hanedai and A. f. formosicola. However, the A. flavopunctatum opulentum and A. yunnanensis are only cited for future work, due to the lack of available materials. Key to the other species and subspecies are revised, and photos showing diagnostic characters and coloration are presented. The male genitalic characters for accurate identification were separately discussed.
