Abstract
The Korean Olethreutinae comprises 277 species. In this study, two species of Olethreutinae: Hedya corni Oku, 1974 and Epinotia salicicolana Kuznetzov, 1968, are reported for the first time from Korea. Our records of Hedya corni are based on three specimens in both sexes from Islands Bogildo and Geojedo. The Korean record of Epinotia salicicolana is based on one male specimen from Muan-gun. The present records of Hedya corni represent the first occurrence out of Japan. Hedya corni is similar to Hedya inornata (Walsingham) but differs from the latter in having the reddish brown forewings. Epinotia salicicolana is similar to Epinotia solandriana (Linnaeus) but differs from the latter in having the smaller dorsal patch on the forewing. Habitus and genitalia of the two olethreutine species are illustrated and briefly described. Their bionomics and distribution are summarized. With our new records, the species numbers of the Korean Hedya and Epinotia are increased to 11 and 23, respectively.
