This study was conducted to review the family Cosmopterigidae in Korea with taxonomic arrangement. In this study, a total of 27 species of 8 genera within 3 subfamilies were recognized from Korea. Among them, four species, Pyroderces sarcogypsa (Meyrick, 1932), Cosmopterix argentitegulella Sinev, 1985, C. setariella Sinev, 1985 and Labdia citracma (Meyrick, 1915) are reported for the first time from Korea. All the known species were examined and briefly redescribed with illustrations of the adult and male and female genitalic structure. Also their available information, including the distributional ranges, host plants and biological data, is enumerated when available.
