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.

The subtribe Olethreutae Diakonoff (1973) which is one of the large subtribe in the subfamily Olethreutinae in the Tortricidae. Diakonoff classified the Olethreutae into a total of 27 genera and three genus groups: Olethreutes, Hedya, and Apotomis. According to the check list of insects from Korea (KSAE & ESK, 2021), 62 species from 11 genera of Olethreutae have been recorded in Korea. This study, provided with redescriptions, distribution, host plants, along with illustrations of adults, male and female genitalia are given.

According to Diakonoff (1973) subtribe Olethreutae is classified into a total of 27 genera and three genera groups: Olethreutes, Hedya, Apotomis. Up to data, 62 species belonging to 11 genera of Olethreutae have been reported in Korea(KSAE & ESK, 2021). In this study, we provide a checklist of subtribe Olethreutae with illustrations of adult, and genitalia of example species of each genus group.

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.

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.

The genus Parapammene Obraztsov, 1960 belonging to the subfamily Olethreutinae, family Tortricidae includes very small to small moths. The genus is characterized by the followings: forewing with median fascia and speculum, and without whitish stria below apex; tegumen of male genitalia being a broad band with the top emarginate laterally; seventh stenite of female genitalia, excavated in posterior edge (Horak, 2006). This genus comprising about 16 species in the world (Brown, 2005). In palaearctic region, there are about 10 known species, 5 species are recorded from Oriental region, and one species in Australian region (Komai, 1999). Comprehensive reviews of genus Parapammene Obraztsov have been given by Obraztsov (1960), Danilevsky and Kuznetzov (1968), and Razowski (1989) and Komai (1999). The following character states support the monophyly of Parapammene (Komai, 1999): 1) ductus bursae with a narrow, band-like sclerite; 2) seventh sternite of female a convex (not flat) plate; 3) S2 without anterolateral processes. In this study, the genus Parapammene Obraztsov are reported for the first time from Korea, with the first record of parapammene selectana (Christoph, 1881), P. petulantana (Kennel, 1901) and P. aurifascia Kuznetzov, 1981. Morphological characters of this genus are redescribed with illustrations of adults, male and female genitalia.

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 genus Dichrorampha Guenée, 1845 belong to subfamily Olethreutinae, family Tortricidae described about 110 species in the Holarctic region (Brown, 2005). In Palaearctic region, there are about 90 species and about 20 species found in Nearctic region; 54 species are recorded from Europe (Razowski, 2003). Danilevesky and Kuznetsov (1968) established the subtribe Dichroramphae by the genus Dichrorampha Guenée. Razowski (1989), proposed the usage of Lipoptychina instead of Dichroramphae since the former name is older. Komai (1999) referred to the group as the Dichrorampha genus-group and added Pammenemima Diakonoff (= Titanotoca Diakonoff) to the group (Horak, 2006). Since Park (1983) reported two species of the genus for the first time from Korea, they are mainly studied by Park and Ahn (1986), Byun, Bae and Park (1998), Oh, Bae and Park (2001). Four species have been reported to present from the Korean peninsula. In this study, Dichrorampha gueneeana Obraztsov, 1953 is report for the first time from Korea. D. gueneeana Obraztsov, 1953 resembles with D. latiflavana Caradja, 1916 superficially, but the former is easily distinguished from the latter by following characters: dorsal patch of forewing color pale yellowish, and smaller than D. latiflavana Caradja, 1916; sclerite of colliculum slender; bent proximally and ductus bursae broader than D. latiflavana Caradja, 1916. Morphological characters of this species are redescribed with illustrations of wing venation and genitalia.

Leaf roller moths Olethreutinae is the second largest subfamily in Tortricidae, comprising worldwide more than 4,300 species (Horak, 2006). Of which, 465 species of 88 genera in South Asia (Diaknoff, 1973). In Vietnam, when studying on fauna of the agricultural pests, National Institute of Plant Protection (NIPP) recorded only 4 Tortricidae species (1977-1978), and 3 Tortricidae species (1997- 1998). From 1996 to 2001. Kuznetzov reported two new genera Fibuloides gen. nov., Pammenpsis gen. nov., and 19 species of Olethreutinae. He also has created a list of 208 Tortricidae species in the North Vietnam. Recently, Razowski recorded 33 species, 11 genera (2008), he (2009) also reported 107 species, 61 genera, of which 61 species of 41 genera belong to Olethreutinae in the North Vietnam. Of which, 25 species are described as new to science, 13 species are new to Vietnam. In the present study, we are briefly reviewed of subfamily Olethreutinae in North Vietnam. We recognized 105 species of 51 genera. Of them, 50 species are reported for the first time from North Vietnam such as: Andrioplecta pulverula Meyrick, 1912; Cryptophlebia repletana Walker, 1863; Dactylioglypha tonica (Meyrick, 1909); Lobesia aelopa Meyrick, 1997; Lobesia ambigua Diaknoff, 1954, etc. The materials identification base on the collection of University of Incheon, which has collected in North Vietnam from 2004-2009.

The genus pammene Hübner, [1825] is one of the genera related to Grapholita Treitschke, 1829, belonging to the tribe Grapholitini of the subfamily Olethreutinae (Bae & Park, 1998). The genus is mostly distributed in the Holarctic region, with about 100 species in the world. Danilevsky & Kuznetzov (1968) divided the genus into the two subgenera, Pammene and Eucelis. Komai (1999) discussed the phylogenetic position within the tribe. Since Park (1983) reported one species of the genus for the first time from Korea, they are mainly studied by Byun & Park (1993), Byun et al. (1998) and Bae & Park (1998). Up to date nine species have been reported from the Korea by Bae and park (1998). In this study, Pammene gallicolana Lienig & Zeller, 1846 is report for the first time from Korea. This species resembles with Pammene ignorata superficially, but P. gallicolana is easily distinguished from the latter by following characters: dorsal patch much larger, basal cavity much bigger, and apophysis posterior longer than P. ignorata, respectively. Morphological characters of this species are redescribed with illustrations of genitalia.

The genus Cydia Hübner is distributed in all the continents, with the tropical regions. However, It's rather insufficiently studied. In palaearctic, there are about 100 known species, less than half of this amount is Nearctic region; 49 species are recorded from Europe. The repartition areas of some species are wide, of some other small, however, they extend during the studies. The genus Laspeyresia Hübner, 1825, which was often used instead of Cydia until the late 1970s is help to be a junior homonym of Laspeyresia R.L,. 1817, an emendation of Laspeyria Germar, 1810 (Noctuidae). Comprehensive reviews of Cydia have been given by Heinrich (1926), Obraztsov (1959), Danilevsky and Kuznetzov (1968), and Razowski (1989). Komai (1999) discussed the phylogenetic position within the tribe (Horak, 2006). In the present study, the Korean species of genus Cydia are reviewed. A　total of 10 species are recogniged. Of them, Cydia danilevskyi (Kuznetzov, 1973) and Cydia indivisa (Dailevsky, 1963) are reported for the first time from Korea. Morphological characters of this genus are redescribed with illustrations of adults, wing venation, male and female genitalia. Distribution map, data matrix, cladistic analysis are provided.

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

The tortricid moths genus Cydia Hübner includes many species of economic importance due to the damage they inflict on agricultural crops, especially fruit and nut trees. Some Cydia species are an important food source for other animals, and some have been used as agents of biological control. Cydia species are generally small dull brown moths with yellow or white wormlike larvae. This group was defined by the combination of the following characters: Apical segment porrect; forewing apex rounded; M2 and M3 sub-parallel; hindwing M3 separate CuA1; uncus absent; socius rounded; corpus bursae with two segnum, like hook-shape; ductus bursae sclerotized. In this study, the Korean species of genus Cydia are reviewed. A total of 10 species are recognized. Among them, two species are newly recorded from Korea for the first time. Adults and genitalia of both sexes are illustrated. Distribution map, data matrix, cladistic analysis are provided. Also illustration of adults, venations, male and female genitalia are provided.
