The genus Spinarge, previously represented by three Chinese species, is redefined to include 11 Palaearctic species, and is transferred from the Athermantini to the Argini of the Arginae. This genus is characterized by the fifth abdominal tergum with a dark median line (=inconspicuous median groove) in the female and a long median process in the male. A key to the world species and descriptions or redescriptions of the following nine species are given: S. affinis sp. nov. from Japan, S. chrysoptera (Gussakovskij, 1935), comb. nov. from China, S. fulvicornis (Mocsary, 1909), comb. nov. from Japan, Korea and China, S. flavicostalis sp. nov. from Japan, S. metallica (Klug, 1834), comb. nov. from Europe to Kamchatka, Primorskij kraj, Sakhalin and Korea, S. nigricornis sp. nov. from Japan, S. prunivora sp. nov. from Japan and Korea, S. pumila sp. nov. from Japan, and S. sichuanensis Wei, 1998, from China. Larvae are gregarious leaf feeders on broad-leaved trees such as Betula, Prunus and Sorbus.

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.
