Study on four genera of Diplazontinae (Hymenoptera: Ichneumonidae) in South Korea with description of two new species

Abstract

Of 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 were previously recognized from South Korea. In previous studies we reviewed eight Diplazontinae genera were reviewed. In this current paper, one genus, EnizemumFörster, is recorded from this country for the first time with one newly described species, E.nigrocoxatumBalueva and Lee sp. nov. Also other three genera, Homotropus Förster, Syrphoctonus Förster and Syrphophilus Dasch, are reviewed here. Here we provide key and diagnosis to eight species of Homotropus including one new species, Homotropus sepiatusBalueva and Lee sp. nov., and key and diagnosis to two species of genus Syrphoctonus and two species of genus Syrphophilus.
