With the discovery of Didineis sibirica and Alysson moticola in South Korea, the tribe Alyssontini Dalla Torre of the Korean Peninsula is supplemented. The genus Didineis Wesmael is reported for the first time in the Korean Peninsula. It is easily separated by the following combination of characteristics from the genus Alysson, another member of Alyssontini occurring in the Far East. In both sexes, fore wing media diverging much before cu-a; metapleuron much less half as long as high; metasomal tergum 2 without pale spots. In males, the last antennal segment is strongly incurved and opposed by a projection from antennal segment 12. Alysson monticola is also new to Korea. Of the Far Eastern species with triangular propodeal enclosure, this species is unique with extended inter-antennal marking. In this study, list of all the known Korean species of the tribe, diagnostic characteristics and digital images are provided.
