The group of species allied to Pediobius alcaeus (Walker, 1839) [considered as the genus Epipleurotropis by Girault (1917)] of the genus Pediobius is reviewed. The group includes P. alcaeus, P. termerus (Walker, 1839), P. coxalis Boucek, 1965, P. fastigatus Kamijo, 1983, and a new species, P. ikedai sp. n., described from Japan (Hokkaido). Eupleurotropis Girault, 1917 (considered as a synonym of Pediobius) is synonymized with Proacrias Ihering, 1914, based on peculiarities of the propodeal structure, and the type species of the former genus is transferred to the latter genus [Pr. testaceipes (Crawford, 1914), comb. n.]. The status of the alcaeus species group in the genus Pediobius is discussed. Many new geographic records are presented, including new data on distribution of the discussed species in the Kuril Islands.
