In this article, three species, Olethreutes castaneana (Walsingham, 1900), Rudisociaria velutina (Walsingham, 1900), and Phaecasiophora fernaldana Walsingham, 1900, of the six species, which have been uncertain in distribution of the Korean peninsula, are rediscovered during the examination of the material preserved in the Natural History Museum, London. Also, one species, Zeiraphera griseana [Hübner (1799)], which was recently found in Korea, is discussed. Of them, two species, Eucosma rigidana Snellen, 1883 and Rhyacionia duplana [Hübner, (1813)], are still uncertain for their distribution in Korea. All available synonymic checklists of the species in this study were provided with taxonomic arrangements.
