Introduction In this article, we described two new species of Cochylidia, which were collected in the Gangwon province and Mt. Halla in The genus Cochylidia Obraztsov 1956 consisted of small-sized Jeju. All the available information for each species, including its belonging to the tribe in the family Tortricidae. It diagnosis, localities, and images of adults, genitalia, and wing has a very small group with only 11 described species in the world venation were provided. Also, the checklist of the genus from Korea (Brown 2005; Sun & Li 2012). At first, the genus was grouped by is given, finally listed for seven species of the Cochylidia. Pierce and Metcalfe (1922) with the name “Genus 16”. Later, it was named as Cochylidia based on the type species Tortrix subroseana Materials and methods Haworth 1811 by Obraztsov (1956). Razowski (1970) listed seven species and one subspecies of Palearctic region by synonymizing All the materials of this study were deposited at the Systematic “ some species to Cochylidia. In the World Catalogue of , Entomology Laboratory, Hannam University, Daejeon, Korea (SEL/ ” Volume 5: Tortricidae (Brown 2005), eight species and one sub- HNU). The specimen images were taken using the digital camera species were listed. Later, three species were added to the genus by attached to the microscope, LEICA M205C (Ⓒ Leica Microsystems, Sun & Li (2012) from . Wetzlar, Hesse, ). Also, genitalia dissection and observa- fi In Korea, the rst record of the Cochylidia was reported by Park tion of wing venation for the species were conducted following the (1976) with three new species, Cochylidia contumescen Meyrick method of Holloway et al (1987). The abbreviations used in this 1931, Cochylidia richteriana Fischer von Röslerstamm 1837, and article are as follows: CN, Prov. Chungnam; GB, Prov. Gyeongbuk; Cochylidia subroseana Haworth 1811. Later, Byun et al (1996) added GG, Prov. Gyeonggi; GN, Prov. Gyeongnam; GW, Prov. Gangwon, JN, two species for the Korean fauna as follows: Prov. Jeonnam; JJ, Is. Jeju; TL, Type locality; HNUSEL, Hannam Herrich-Schäffer 1851 and Rösler 1864. Thus, University, Systematic Entomology Laboratory.
