In North Korea, the Tortricidae has been poorly studied until Byun et al. (1998) reviewed 350 species from Korea, including 63 species of Tortricinae and 40 species of Olethreutinae. Then Razowski (1999) presented a checklist of 358 species of Tortricidae from Korea, including 176 species of the North Korean Tortricidae with mostly based on the avaialble materials in Poland and previous literatures. Later, a serial studies on the family Tortricdae of North Korea with the material deposited in the Hungarian Natural History Museum provided several additional data for the North Korean tortricid fauna (Byun 2009; Byun 2011a; Byun 2011b; Byun 2011c; Byun et al. 2007)
During the course of the study on the Tortricidae of North Korea deposited in Hungarian Natural History Museum, the author found three species of Olethreutes for the first time from North Korea. Of them, Olethreutes aviana Falkovitsh is also newly reported to the Korean peninsula. The aim of the present study is to report the three species of Olethreutes as new to North Korean fauna. In the present study, three species of the genus Olethreutes: O. aviana Falkovitsh, O. obovata (Walsingham), and O. orthocosma (Meyrick), based on the material deposited in the Hungarian Natural History Museum, are reported for the first time from North Korea. Among them, O. aviana Falkovitsh is recorded as new to the Korean peninsula. Photographs of the adults and genitalia of the species are presented.
