The genus Cydia Hübner is distributed in all the continents, with the tropical regions. However, It's rather insufficiently studied. In palaearctic, there are about 100 known species, less than half of this amount is Nearctic region; 49 species are recorded from Europe. The repartition areas of some species are wide, of some other small, however, they extend during the studies.
The genus Laspeyresia Hübner, 1825, which was often used instead of Cydia until the late 1970s is help to be a junior homonym of Laspeyresia R.L,. 1817, an emendation of Laspeyria Germar, 1810 (Noctuidae). Comprehensive reviews of Cydia have been given by Heinrich (1926), Obraztsov (1959), Danilevsky and Kuznetzov (1968), and Razowski (1989). Komai (1999) discussed the phylogenetic position within the tribe (Horak, 2006).
In the present study, the Korean species of genus Cydia are reviewed. A　total of 10 species are recogniged. Of them, Cydia danilevskyi (Kuznetzov, 1973) and Cydia indivisa (Dailevsky, 1963) are reported for the first time from Korea. Morphological characters of this genus are redescribed with illustrations of adults, wing venation, male and female genitalia. Distribution map, data matrix, cladistic analysis are provided.
