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.

Eucosmini Meyrick, 1909 is one of the largest groups in subfamily Olethreutinae, with more than 1,650 species of 128 genera. In Korea, 96 species of 26 genera have been recorded by several authors (Park, 1981, Bae, 1992, et al.). In this study, we provide a brief overview and a checklist of Eucosmini, with illustrations of adults and genitalia for examined species.

The tribe Eucosmini is the second largest tribe of Olethreutinae with more than 1,000 species in over 125 genera, distributed mostly in the Holarctic region, and over half of the known species occur in the Nearctic region (Horak and Brown, 1991b). Enarmonia Hübner, Ancylis Hübner, and its allied genera are tentatively retained in Eucosmini, although they have been treated as the subtribe Enarmoniina (Razowski, 1989) belong to Eucosmini maybe distinguished from other tribes by a combination of the following characters proposed by Kuznetsov and Stekolnikov (1984): 1) one-branched protuberance of the valve; 2) gnathos and uncus very weakened or reduced. In Vietnam, in the period 1977-1978 and 1997-1998, National Institute of Plant Protection (NIPP) recorded only seven Tortricidae species. But none of them are Eucosmini. Recently, Kuznetzov (2001) recorded four species in the South Vietnam: Eucosmogastra aeolantha (Meyrick, 1914), Noduliferola pleurogramma (Clarke, 1976), N. atriplaga (Clarke, 1976), N. phaeostropha (Clarke, 1976). Razowski recorded 14 species of 10 genera of Eucosmini (2009). In this study, we are briefly reviewed of tribe Eucosmini in North Vietnam. As the result of this study, totally 19 Eucosmini species of 13 genera are recognized. Of them, 17 species are reported for the first time from Vietnam such as: Coenobiodes acceptana Kuznetzov, 1973; Epiblema foenella (Linnaeus, 1785); Eucosma calligrapha Meyrick, 1912, etc. The materials identification based on the collection of University of Incheon, which has collected from 2004-2009 in the North Vietnam by Vietnamese and Korean entomologist.

The first list of the family Tortricidae from North Korea was provided by Zhu(1969), including 16 species of the subfamily Olethreutinae. There had been no research on this group, until the report of Park and Byun (1991) with 9 additional species. And Jaros et al.(1992) reported 17 previously unrecorded species, including 4 of Eucosmini. Byun et al. (1998) made a illustrated catalogue of Korean Tortricidae containing 350 species. In 1999, Razowski provided a list of 358 tortricid species in the Korean Peninsula, including 87 species of the subfamily Olethreutinae from North Korea. Among them 29 species of the tribe Eucosmini were included as them to be distributed in North Korea. In this study, we report eight previously unrecorded species of the tribe Eucosmini from North Korea, based on the examination of the material deposited in the Hungarian Natural History Museum. The species, which are known for the first time from North Korea in this study, are as follows. 1. Ancylis melanostigma Kuznetsov 2. Ancylis sativa Liu 3. Eucoenogenes japonica Kawabe 4. Eucosma glebana (Snellen) 5. Notocelia rosaecolana (Doubleday) 6. Rhopobota ustomaculana (Curtis) 7. Spilonota ocellana (Denis et Schiffermüller) 8. Zeiraphera lariciana Kawabe

We report a species of the tribe Eucosmini belonging to the family Tortricidae for the first time from China: Semnostola magnifisa (Kuznetsov) and add four species for the Northeast Chinese fauna: Ancylis badiana (Denis et Schiffermüller), Blastethia turionella (Linnaeus), Eucosma aemulana (Schläger), and Sillybiphora devia Kuznetsov. Also Rhopalovalva grapholitana (Caradja) is recorded for the first time from the Province Heilongjiang. Adults and genital characteristics for species are redescribed and illustrated. All available information for their host plants and distributional ranges are given.
