The species-group of Arge aenea (Hymenoptera, Argidae) is proposed for three new species from East Asia : A. aenea sp. nov. from Japan (Hokkaido, Honshu, Shikoku and Kyushu), Russia (Khabarovskij Kraj and Primorskij Kraj), Korea and China (Shaanxi Province), A. tuberculata sp. nov. from China (Shaanxi Province) and A. fulvicauda sp. nov. from China (Shaanxi and Sichuan Provinces). This species-group is characterized by the peculiar structure of the seventh and eighth abdominal terga of the males ; the seventh tergum has a small swelling posteromedially and the eighth tergum has a shallow and wide depression at middle. These character states are unique to the three species in the Argidae and support the monophyly of the species-group. Descriptions of the three new species are given. The larva of A. aenea sp. nov. is a leaf-feeder on Betula.
