Coniopteryginae is a highly diversified group of Coniopterygidae. In Korea, only two species, Semidalis aleyrodiformis and Conwentzia pineticola, are recorded. Here we report two additional species of Coniopteryginae, Coniopteryx pallescens and Conwentzia sinica, as new records in Korea. Brief descriptions, photos of adults and male genitalia as well as COI barcode sequences are provided.
