Subfamily Cryptolechiinae Meyrick 1883 (Depressariidae sensu Heikkila et al., 2014) is reviewed from Korea. The Cryptolechiinae comprising nearly two hundred species worldwide (Wang, 2006), is characterized by forewing broadly lanceolate, the male genitalia without gnathos and female genitalia with well-developed lamella antevaginalis. In the Korea fauna, only four species of two allied genera, Acryptolechia and Cryptolechia, were recognized with two new species. A full bibliography, diagnosis and descriptions for all known species including new species are provided with illustration. Keys to species are also given.
