The tortricid moths genus Cydia Hübner includes many species of economic importance due to the damage they inflict on agricultural crops, especially fruit and nut trees. Some Cydia species are an important food source for other animals, and some have been used as agents of biological control. Cydia species are generally small dull brown moths with yellow or white wormlike larvae. This group was defined by the combination of the following characters: Apical segment porrect; forewing apex rounded; M2 and M3 sub-parallel; hindwing M3 separate CuA1; uncus absent; socius rounded; corpus bursae with two segnum, like hook-shape; ductus bursae sclerotized. In this study, the Korean species of genus Cydia are reviewed. A total of 10 species are recognized. Among them, two species are newly recorded from Korea for the first time. Adults and genitalia of both sexes are illustrated. Distribution map, data matrix, cladistic analysis are provided. Also illustration of adults, venations, male and female genitalia are provided.
