Study on two unrecorded genera, Barycnemis Förster and Phradis Förster (Hymenoptera: Ichneumonidae: Tersilochinae), from South Korea

Six genera of the subfamily Tersilochinae (Barycnemis, Diaparsis, Gelanes, Phradis, Probles and Tersilochus) are recognized in South Korea. Two genera, Diaparsis and Tersilochus, were previously recognized from South Korea, whereas the other four genera are recorded from this country for the first time. All genera found in South Korea, except the almost cosmopolitan Diaparsis, are entirely or predominantly Holarctic. A key to the six genera of Tersilochine occurring in South Korea is provided. Two genera of Korean Tersilochinae (Barycnemis and Phradis) are reviewed here, and a key to the other four species (B.bellator, B.dissimilis, P.kyushuensis and P.nikishenae) is provided in this paper.
