    The genus YpsolophaLatreille 1796, belongs to the family Ypsolophidae, with over 140 described species worldwide. More than 70% of the ypsolophids are described from the Palaearctic and Oriental Regions (Jin et al., 2013). Latreille (1796) established Ypsolopha without a type or any associated species. Taxonomic study of this genus have been carried out by several researchers from the end of 18th to early 20th century: Fabricius (1798), Hübner (1826), Agassiz (1846), Walshingham (1881, 1889), Busck (1903, 1906), and Meyrick (1914-1938). Recently Moriuti (1964, 1977) studied 17 species of Japanese Ypsolopha and classified them into three groups based on foreand hindwing venations, and the shape of labial palpus. Zagulajev (1989) provided 26 species for the European part of the former USSR. In Korea, a taxonomic study of Ypsolopha was carried out by Park (1983), who discovered four species from Korea: Y. blandella, Y. yasudai, Y. strigosa, and Y. acuminata. Later, Y. longa was recognized by Jeong et al. (1995). In 2001, Byun and Park described one new species, Y. nigrimaculata. Also, Byun and Bae (2001) reported 3 newly recorded species from Korea: Y. cristata, Y. japonica, and Y. parenthesella. Up to now, 14 species have been recorded from Korea including Y. amoenella, Y. asperella, Y. contractella, and Y. acerella which were recently reported from Korea (Sohn et al., 2010).

    In this study, two Ypsolopha species, Ypsolopha vittella (Linnaeus, 1758) and Y. nigrofasciataYang, 1977, are recorded from Korea for the first time. Ypsolopha vittella is distributed in the Palaearctic region, while Y. nigrofasciata was recorded only from China and the Far East of Russia. The Diagnosis, description, distribution, host plants, adult photographs, and pictures of female genitalia are provided.

    Materials and Methods

    Specimens examined are based on materials collected from Korea. The specimens were mostly collected using by light traps with a mercury vapor lamp (200V/ 200W). Abbreviations used herein are as follows: TL, type locality; GW, Gangwon Province; GN, Gyeongnam Province; INU, Incheon National University. All of the specimens were deposited at Incheon National University (INU), Incheon, Korea.

    This species is very similar to Y. japonicaMoriuti, 1964, superficially, but can be distinguished by its very short ductus bursae. In addition, Y. vittella has basal half of the corpus bursae sclerotized (Moriuti, 1964) while Y. japonica has this membranous.

Hind leg femur white; tibia to tarsus white, sprinkled with pale brown. Forewing apex acutely produced; ground color pale gray, scattered with black or pale brown; dorsum forming a longitudinal irregular dark patch from near base to near tornus; apex with a black spot; cilia whitish gray. Hindwing with cilia pale grayish brown.
