The Gonatopodinae is the most diverse subfamily among the Dryinids subfamilies. It is recognized about 381 described species in the world. A total three genera and seven species have been reported from Korea (He, J. and Xu, Z., 2002). Generally Gonatopus is easily distinguished from other Gonatopodinae genera by the combination of the following characters: Palpal fomula 6/3, or 5/3 or, or 5/2 , or 4/3, or 4/2, or 3/2; enlarged claw with a subapical tooth, or with a small subapical tooth; Tibial spurs 1, 0, 1. Also, Genus Gonatopus Ljungh, 1810 ranks as the most commonly distributed genus in the world and parasitoids of leaf hopper, Cicadellidae (except for Typhlocybinae, Idiocerinae, Macropsinae) (Olmi, 1984). In this study, we found one newly recorded species, Gonatopus dromedarius (A.costa) and provide a key to the species of genus Gonatopus from Korea
