A taxonomic study was conducted on Spilonota Stephens, 1834 in Korea. As a result of the research based on materials from Incheon National University two new species; S. samseong Choi, Bae & Nasu, and S. laticucullusa Choi, Bae & Nasu from Korea. This study provides a brief description of the new Spilonota species in Korea, as well as comparisons with similar species and illustrations of adult and genital morphology.

The genera Spilonota Stephens, 1834 and Lepteucosma Diakonoff, 1971 are belonging to the tribe Eucosmini, subfamily Olethreutinae. In Korea, there are five species of Spilonota recorded: S. albicana (Motschulsky, 1866), S. eremitana Moriuti, 1972, S. lechriaspis Meyrick, 1932, S. ocellana ([Denis & Schiffermüller], 1775), and S. semirufana (Christoph, 1882). Only one species of Lepteucosma is recorded: L. huebneriana (Kocak, 1980). Both genera are agricultural pests that infest host plants belonging to the family Rosaceae, specifically causing damage to genus Malus (apple trees) and genus Rubus (blackberry plants), respectively. In this study, we provide a checklist of Korean Spilonota and Lepteucosma, with information of host plants and distribution for each examined species.

Genus Spilonota is a small group of the family Tortricidae, including over 29 described species worldwide (Brown, 2005). Most larvae of the genus feed on various plant families including Pinaceae, Rosaceae, Leguminosae, Betulaceae, Salicaceae, and Juglandaceae, with economical importance (Park, 1983, Zhang & Li, 2005). Even though this genus has been relatively well investigated in East Asia: five species from South Korea (Byun et al., 2009); ten species from China (Zhang & Li, 2005); eight species from Russian Far East (Kuznetsov, 2001); thirteen species including four unidentified species from Japan (Kawabe, 1982, Oku, 2003), it has been very poorly studied from North Korea with only two recorded species to date (Razowski, 1999, Byun et al., 2009) The aim of the present study is to clarify the fauna of the genus Spilonota from North Korea, including two new records, based on the material deposited in the Hungarian Natural History Museum, Budapest, Hungary (HNHM). In the present study, the author examined all available material from North Korea. In this study, four species of Spilonota are recognized. Among them, two species, Spilonota lechriaspis Meyrick, 1932 and Spilonota ocellana (Denis et Schiffermüller, 1775), are reported for the first time from North Korea. A key to the species is provided. Photos of adults and the genitalia are provided with brief comments on the distribution.
