Two new species of Dentilabus Heinrich (Hymenoptera: Ichneumonidae: Ichneumoninae) from Japan and Korea, with redefinition of the genus

We discovered Dentilabus Heinrich (Icneumoninae: Platylabini) for the first time from the Eastern Palearctic region. Two new species, D. nigripodus sp. n. [Japan and Korea] and D. iyoensis sp. n. [Japan] are described. Dentilabus nigripodus resembles its Western Palearctic congener, D. variegatus (Wesmael), but they can be easily distinguished by the uniformly black hind femora in D. nigripodus . With the inclusion of D. iyoensis , we also redefine the generic limits of Dentilabus . A key to Palearctic species of the genus is provided.
