Korean species of the genera Adapsilia Waga and Porogeloemyia Hendel are taxonomically investigated. So far, members of Pyrgotidae are known as internal parasites of adult scarabaeoid booties, but host relationships of the above two genera are not known yet. Based on the Korean specimens of these genera, adult external structures, including genitalia of both sexes, are described and illustrated. As a result, we recognized the following 10 species previously unknown in Korea: Adapsilia breviantenna sp. nov. ; A. coarctata Waga; A. cornugaster sp. nov.; A. hispida sp. nov.,; A. longifasciata sp. nov.; A. ochrosoma sp. nov.; A. tenebrosa sp. nov.; Parageloemyia nigrofasciata(Hendel); and P. wonjuensis sp. nov. In addition, we provided a key to the all 14 Korean pyrgotid species and conducted a cladistic analysis to infer phylogenetic relationships among them.
