The family Epermeniidae is a small group, comprising 188 described species with 11 genera in the world. In Korea,the family Epermeniidae has only one described species, Epermenia strictella (Wocke, 1867) to date. In this study, thenewly recorded genus Ochromolopis Hübner, 1824 was reported with Ochromolopis kaszabi minima Budashkin & Satshkov,1991 which is a subspecies of Ochromolopis kaszabi Gaedike, 1973 for the first time from Korea. For the exact identificationamong the species, the DNA barcode was conducted with a brief phylogenetic tree by COI gene. All the available informationincluding distributional ranges and host plants were provided in this study. Also, The images for adult and male andfemale genitalia were provided for the taxonomic study.

Meteorus Haliday is a cosmopolitan genus of the subfamily Euphorinae. This genus comprises more than 330 describedspecies (Muesebeck, 1923; Zitani and Shaw 2002; Zitani, 2003; Shaw and Nishida 2005; Stigenberg, 2008; Aguirre etal., 2015). Most species of Meteorus are koinobiont endoparasitoids of Coleoptera and Lepidoptera larvae (Huddleston,1980; Shaw and Huddleston, 1991). In this study, four species of Meteorus are reported for the first time from Korea:Meteorus brevicauda Thomson, M. colon (Haliday), M. kunashiricus Belokobylskij, and M. vexator (Haliday). Diagnosis,distribution, and host information are provided for each species.

A marine brown alga was collected from Geoje, located on the southern coast of Korea. This species shares the generic features of Dictyota and is morphologically characterized by the combined features of erect or prostrate thallus with smooth margin, dichotomous to subdichotomous branches not twisted at the terminal part, absence of surface proliferations, 1-3 cell layered cortex and unilayered medulla, and lack of involucrum in sporangia subtended by a single stalk cell. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade with Dictyota bartayresiana. The genetic distance between both sequences within the clade was calculated as 1.2%, considered to be within the intra-species range for the genus. Based on these morphological and molecular analyses, this Korean alga is identified as D. bartayresiana described originally from the West Indies. This is the first record of D. bartayresiana in Korea.

Korean species of the genus have been investigated by several researchers (Papp, 1992; Belokobylskij, 2000; Ku et al., 2001). The members of the genus Aridelus parasites on nymphs and adults of Pentatomid species (Shaw, 1985). In this study, Aridelus aulacocentrum is reported for the first time from Korea.

The genus Cosmopterix Hübner is belongs to the subfamily Cosmopteriginae, comprising 11 described species in Korea (Park, 1986; Park, 1994; Sinev and Park, 1994). This genus is major group of the family Cosmopterigidae, with a specific character having the orange postmedian band and silvery-metallic fascia on the forewing. In this study, two species, Cosmopterx argentitegulella Sinev and C. setariella Sinev, are reported for the first time from Korea. Adult and genitalic structure are examined and illustrated. Also, available information, including the distributional ranges, collecting localities and host plants are provided. Consequently 13 species have been recorded in Korea until now.

Chrysopidae is a cosmopolitan group of Neuroptera, with 85 genera and 1,200 species recorded in the world. Genus Nineta is a small group of the family, with almost 20 species recorded worldwide. They can be recognized by large sized body than that of other genera. In Korea, only one species, Nineta vittata (Wesmael, 1841) has been recorded so far. Here we present Nineta itoi, another new record, in Korea. Here we provide a brief description, photos of adult and male genitalia, COI barcode sequence, and a key based on diagnostic characters.

The genus Argyresthia Hübner, 1826, belongs to the family Argyresthiidae, with over 150 described species worldwide. Among them, over 70 species are distributed in Palearctic Region. In Korea, a total of four species have been reported from Korea. In 1968, the apple fruit moth, Argyresthia conjugella Zeller is reported by The Zoological Society of Korea. Sohn (2007) reported three known species of this genus: Argyresthia ivella Haworth, A. laevigatella, Herrich-Schäffer and A. magna Moriuti.

Chalcididae Latreille, 1817 currently include 1,464 extant species in 87 genera in the world. This family is probably easy to define taxonomically. Body robust with coarse puncture, prepectus extremely narrow, hind femur typically swollen and on inner margin with one or more teeth. Members of this family are primary endoparasitoids on pupa of Diptera and Lepidoptera. Up to date, only 12 species of 6 genera belonging to three subfamilies have been recorded from South Korea. As a result of this study, six species (Chalcis sp. 1, Conura sp. 1, Haltichella cf. nipponensis Habu, Hockeria cf. bifasciata Walker, Proconura sp. 1 and Steninvreia cf. petiolata Bouček) in Chalcididae are recorded for the first time in South Korea. Among them four genera (Haltichella Spinola, Hockeria Walker, Proconura Dodd and Steninvreia Bouček) are recorded for the first time in South Korea. Therefore, 18 species of 10 genera in Chalcididae are recorded from South Korea.

Pteromalinae Dalman, 1820 are the largest subfamily in Pteromalidae and currently include 2,073 extant species of 314 genera. This group is probably difficult to define taxonomically. Members of this subfamily are endoparasitoids of Lepidoptera, Diptera and Coleoptera larvae and pupae. Up to date, only 46 species of 30 genera belonging to five subfamilies have been recorded from South Korea. As a result of this study, we reported 25 unrecorded species of 13 genera for the first time from South Korea. Therefore, 71 species of 43 genera in Pteromalinae are recorded from South Korea.

Leucospidae Walker are a relatively small family in Chalcidoidea, and they consist of four genera and about 140 species in worldwide. In neighboring countries, 12 species are known from China and four species are known from Japan, but only one species is known from South Korea by Paik (1974). In this study, Leucospis yasumatsui Habu is reported for the frist time from South Korea. A key to South Korean species of the genus Leucospis Fabricius, diagnosis, photos of characteristics and distribution from South Korea are provided.

Monodontomerus Westwood is widely distributed genus in Torymidae Walker, and it consists of 41 species with one fossil species.

Netelia Gray, 1860, a largest genus within the subfamily Tryphoninae and its distribution is worldwide. The members of Netelia are known to be ectoparastic koinobionts of lepidopteran larvae. More than 330 species have so far been recorded and divided into 12 subgenera. Among them, the subgenus Amebachia Uchida, 1928 was reported as a genus by Uchida (1928) based on Amebachia baibarana from Taiwan. The lectotype of Amebachia baibarana Uchida, 1928, was re-examined and then this species should be a subgenus of the genus Netelia by Konishi (2010). Consequently, five currently valid species of Netelia (Amebachia) have been described in the world. As a result of the present study, the subgenus Amebachia belonging to the genus Netelia is reported from South Korea for the first time based on a species of Netelia (Amebachia) rasilella and N. (A.) yoshimatsui. Redescriptions and photographs of the diagnostic characters of two species are provided. This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2016R1A6A3A03007788).
