Genus Cochylidia, belonging to the tribe Cochylini under the family Tortricidae, consists of small-sized moths, which is one of the small group with only 11 described species until now (Brown 2005; Sun & Li 2012). Recently, Brown (2005) listed eight species and one subspecies. Later, three species were added to the genus by Sun & Li (2012) from China. In Korea, Park (1976) reported the genus Cochylidia with three unrecorded species, C. contumescen Meyrick, C. richteriana Fischer von Röslerstamm, and C. subroseana Haworth from Korea. Later, Byun et al. (1996) reported two additional species from Korea: C. heydeniana Herrich-Schäffer and C. moguntiana Rösler. Recently Byun et al. (2017) reported the genus in Korea with two new species, C. flavifasciatus Byun and C. hallasanensis Byun. In this study, we provide the checklist with its external characteristics, localities, and images of adults and genitalia.
