The Banchinae are a large cosmopolitan subfamily that includes approximately 1,700 species in 65 genera. The number of species in South Korea is still pooly known and only 18 of the 275 Eastern Palaearctic species have been reported. Most species are koinobiont endoparasitoids of Lepidopteran larvae and pupae. A few banchines also parasitize Coleoptera and Hymenoptera. This subfamily is divided into three tribes; Atrophini, Banchini and Glyptini. The former is the largest tribe with 953 species in 40 genera, and is easily distinguished from two other tribes by the tergites without oblique grooves and the nevellus which is intercepted at middle. Cryptopimpla is moderately large genus with worldwide distribution. As a member of tribe Atrophini, Cryptopimpla can be distinguished by follow: Occipital carina connected with hypostomal carina; epomia absent; lower half of mesopleuron weakly convex; ovipositor sheath 0.5-1.0 times as long as hind tibia; ovipositor tip with subapical dorsal notch. Until now the genus was not found in Korean fauna. Here we report four species, two of them are described as new to science. The description is given also for newly reported male of Cryptopimpla brevigena Kuslitzkii and C. carinifacialis Sheng. A key for South Korean species is proposed.

Psilomma Förster, a small and rare genus within the tribe Pantolytini (Diapriidae: Belytinae), consists of three species widely distributed in Europe: P. dubium Kieffer, 1908; P. fuscicornis Kieffer, 1908; P. fusciscapis Förster, 1861 (Macek 1990). This genus is easily distinguished from other Pantolytini genera by the sickle form of mandibles. Up to date, Psilomma has not yet been recorded out of Europe. As a result of the present study, the genus Psilomma is reported from the South Korea for the first time based on a species of P. dubium. Also, the known range of Psilomma is extended from Europe (Western Palaearctic) to South Korea (Eastern Palaearctic). A detailed redescription, photographs of this species are given.

The subfamily Allantinae is one of the large subfamilies within the family Tenthredinidae with about 900 described species in the world. All of the species are worldwide distributed and 322 of them are from Eastern Palaearctic region. Also, in the neighboring countries, it has been recorded that 275 species in China, 90 species in Japan and 131 species in Russia. But only 15 species have been reported in South Korea. Generally subfamily Allantinae can be easily recognized from other subfamilies by the following characters in fore wing: Veins M and Rs+M meeting Sc+R at or very near the same point; vein 2A+3A complete, always separated from 1A by an anal crossvein; veins M and 1m-cu parallel; vein 2r present. Moreover, all larvae of Allantinae are phytophagous and external feeders on the foliage of the host. In this study, we report eight species belonging to the five genera (Allantus, Ametastegia, Apethymus, Asiemphytus and Taxonus) from South Korea for the first time. As a total of 11 genera and 24 species in Allantinae were identified to occur in South Korea. A key, diagnoses and photographs of the diagnostic characters are provided.

The subfamily Cylloceriinae were recorded 33 species of three genera, Allomacrus Förster (five species), Cylloceria Schiødte (27 species) and Rossemia Humala (one species), worldwide. The genus Cylloceria can be recognized by following characters: head and face wider than high; anterior margin of clypeus impressed; basal flagellomeres strongly elongate; mesoscutum with distinct notauli; tarsal claw simple; ovipositor long, equal or longer than metasoma. In male of Cylloceria, 3rd and 4th antennal flagellomeres with tyloids of specific shape, which is semicircular emargination and rather deep and distinct. In this study, Korean species of the genus Cylloceria Schiødte are reviewed. Five species of Cylloceria and the subfamily Cylloceriinae are reported for the first time from South Korea, including one new species. Description with photographs of the new species, diagnoses, and a key to South Korean species of Cylloceria are provided.

Orussidae is a unique family belonging to the ‘Symphyta’, Hymenoptera. It is a small group of parasitoid sawflies, consisting of about 90 known extant species in 15 genera in the world. Most species of Orussidae are thermophilous and imagines are active during the hottest hours of the day. Therefore, orussids are rarely collected. They are known to be idiobiont ectoparasitoids of larvae of wood-boring beetles such as Buprestidae and Cerambycidae or Hymenoptera such as Siricidae and Xiphydriidae, although records of orussids parasitizing introduced siricids in New Zealand do not constitute a natural host relationship. Within the family, Orussus is the largest and most widely distributed genus. Currently, 28 valid species are recognized. Recently, Vilhelmsen et al. (2014) reported three new species of the genus Orussus from the Oriental region. Here we describe a new species, Orussus sp. nov., from South Korea and provide a revised key to the eastern Palaearctic species of Orussidae. Also, phylogenetic analyses place the new species basally in Orussus, together with other species from the Far East.

Fivenewly recorded subfamilies, Diacritinae, Microleptinae, Orthocentrinae, Orthopelmatinae, and Phrudinae, were the small and rare subfamilies of the family Ichneumonidae except Orthocentrinae. The first subfamily Orthocentrinae have been reported 31 genera with 481 species worldwide but we have a very poor knowledge of this subfamily in Korea. This subfamily is known for larval koinobiont endoparasitoids of Diptera (Humala, 2008). The second subfamily Diacritinae have been reported six species in the world and distributed four species in the Eastern Palaearctic (Yu et al., 2012). The third subfamily Microleptinae have been recorded only one genus with 13 species in the world. Among them 10 species are distributed in the Eastern Palaearctic. The fourth subfamily Orthopelmatinae have been reported nine species of one genus in the world, five species in the Eastern Palaearctic. The final subfamily Phrudinae have been reported 29 species in the world, five species in the Eastern Palaearctic. The subfamily Eucerotinae have been recorded 50 species in the world and four species from Korea. This subfamily is known for hyperparasitoids of Ichneumonoidea (Wahl & Sharkey, 1993). In this paper we report not only five newly recorded subfamilies new to Korean fauna but also eight newly recorded species included two species of Eucerotinae for the first time from Korea.

It was first recorded that Elasmus japonicus Ashmead had occurred from three Polistes nests in Busan city, Wanju-gun, and Pyeongchang-gun of South Korea. The 2 females and 14 males were collected from the nest of Polistes rothneyi koreanus in Busan city (N35°17′57.71″ E129°06′33.24″), 12 females and 2 males from P. djakonovi in Wanju-gun (N35°47′35.05″ E127°15′30.48″), 18 females and 3 males from P. snelleni in Pyeongchang-gun (N37°39′7.84″ E128°35′15.81″). P. rothneyi koreanus and P. djakonovi were first recorded as new hosts. To date, two Elasmus species, E. nephantidis and E. viridiceps, have been reported from South Korea. In this study, we provide diagnosis, description, and photos of female and photos of male of E. japonicus.

The subfamily Sterictiphorinae which include 324 species from 26 genera is widespread group of sawfly. Most recorded species of Sterictiphorinae distributed in the Palaearctic, Nearactic, Oriental and Afrotropic regions. Among them, only 20 species have been reported from the Eastern Palaearctic region. Unfortunately, this group is very poorly studied in Korea. In the Korean fauna were reported only one species, Sterictiphora tanoi Togashi 1997(Togashi, 1997). The larvae of genus Sterictiphora feed on cherry and serviceberry (Smith, 1979). The adults of genus Sterictiphora are easily distinguished from the other genera of Sterictiphorinae by following characters: convex anterior margin of the head in dorsal view, hind wing with very long anal cell. As a result of this study, we report five new species, Sterictiphora rugosa sp. nov., S. gapjangensis sp. nov., S. flavicollis sp. nov., S. koreana sp. nov. and S. daeguensis sp. nov. and provide a key to Korean species and diagnosis with photos of five new species.

The genera Aproceros and Yasumatsua have not been recorded in Korea previousely. Genus Aproceros is small genus among genera of subfamily Sterictiphorinae with 10 described species. Almost species of this genus recorded in Eastern Palaearctic region except A. scutellis Wei & Nie, 1998 from Oriental region. Also, genus Yasumatsua has been reported only two species: Y. albitibia Togashi, 1990 and Y. nigra Togashi, 1970 in the world. Key characters of the genera Aproceros and Yasumatsua as following: (1) Aproceros: anal cell of hind wing absent; head narrowed behind eyes; basal anal cell of fore wing open, (2) Yasumatsua: anal cell of Hind wing closed; claw with a basal lobe; face between antennal sockets narrow with sharp median carina (Meicai, 1997). Biology and ecology of these two genera are poorly studied. In this study we record one unrecorded species of genus Aproceros and described one new species of genus Yasumatsua from Korea. Also, key to korean genera of subfamily Sterictiphorinae, diagnoses of Aproceros and Yasumatsua and photos of morphological characters are provided.

Genus Litochila Momoi belonging to the tribe Hemigasterini is represented by eight species from Korea, China, Japan, Taiwan and India. Modern taxonomic revision of this genus was carried out by Kaur (1988). He and Chen (1996) enlarged the genus by adding one species, L. guizhouensis He & Chen from the oriental part of China. They provided a key to Chinese species and descriptions without including L. sinensis Kaur which was previously reported from Fujian, China by Kaur (1988). As a part of a large revisionary work of the subfamily Cryptinae, four species, L. nohirai (Uchida), L. carbonaria (Smith), L. jezonica (Uchida) and L. sinensis, are recognized from Korea. L. carbonaria. L. sinensis and L. jezonica are reported from Korea for the first time. The species L. guizhouensis is synonymized with L. sinensis. The distinction of females of two closely resembling species, L. carbonaria and L. jezonica, is possible by the number of flagellar segments, the shape of mesopleurum and second tergite, but males are difficult to identify. Momoi and Okamoto (1965) relied on the number of tyloids to identify them, and Kaur (1988) used the shape of postpetiole except for such character. However, our observations revealed these characters are not useful in relating these males, because many variations were found in these characters. Therefore, further DNA studies will be required to resolve this controversy.

Probles is apredominantly Holarctic genus with about 44 species in the Palearctic region (Yu et al. 2012). Palearctic fauna of Probles is rather irregularly studied: West European species were revised by Horstmann (1971, 1981; Horstmann and Kolarov 1988), and Palearctic species of five small subgenera, Microdiaparsis Horstmann, Probles s. str., Rhynchoprobles Horstmann, and Rugodiaparsis Horstmann, were reviewed by Khalaim (2003), whereas the most species rich subgenus, Euporizon Horstmann, is virtually unknown outside Europe. Only two species of Euporizon, P. (E.) sibirica Khalaim, 2007 from Mongolia and Russian Siberia and P. (E.) vulnifica Khalaim & Sheng, 2009 from the Palearctic part of China, are known to occur in the East Palearctic region, and one Oriental species, P. (E.) vietnamica Khalaim, 2011, was recently described from Vietnam (Khalaim, 2011; Khalaim and Sheng 2009). Some species of Probles were recorded as parasitoids of the beetle families Ciidae, Curculionidae, Endomycidae, and Melandryidae in Europe (Horstmann 1971, 1981). In this paper, we describe three closely related new species of Euporzon belonging to one species-group. Three closely related species of the genus Probles Förster, P. fulgida sp. n., P. korusa sp. n., and P. rukora sp. n. differ from other Palearctic species of the genus based on a combination of long and weakly sinuate apically ovipositor and short temple. A portion of the key for identification of this species-group is provided here.

The genus Thomsonina is a small group of Proctotrupidae, with two described species in Palaearctic region: T. boops from Europe; T. scymni from Japan. These species are parasitoids of Scymnus (Coleoptera: Coccinellidae). Genus Nothoserphus was erected on the single species N. mirabilis Brues (1940) from Taiwan (Oriental). Since then two genera, Thomsonina Hellén (1941) from Europe (Western-Palaearctic) and Watanabeia Masner (1958) from Japan (Eastern-Palaearctic), proposed and the taxonomy was revised by Townes (1981) who synonymized Thomsonina and Watanabeia, including three species groups (boops- group, afissae-group and mirabilis-group). At present one genus classification Nothoserphus, is universally accepted. But, Masner (1958) suggested that Thomsonina and Watanabeia should be separated in two distinct genera from the Nothoserphus. This is supported by the different characters and biological data. In this study, the Authors are also agree to the Masner’s proposal and first report the genus Thomsonina from South Korea based on T. scymni. Also, we provide comparison of main different characters and host data for three genera.

The superfamily Proctotrupoidea is cosmopolitan and diverse group comprising 11 extant families: Austroniidae, Diapriidae, Heloridae, Maamingidae, Monomachidae, Pelecinidae, Peradeniidae, Proctorenyxidae, Proctotrupidae, Roproniidae, Vanhorniidae. But, Recently a separate superfamily Diaprioidea was recognized to include Diapriidae, Monomachidae and Maamingidae (Sharkey, 2007; Sharkey et al., 2012). Among them, three families are found in South Korea: Heloridae (Choi et al., 2012), Diapriidae (Notton, 1994), Proctotrupidae (Choi et al, 2012; Lee et al., 1988; Lee et al., 2008). Proctorenyxidae Lelej & Kozlov, a very small family of Proctotrupoidea, contains only 2 genera with 2 species in the world: Hsiufuropronia chaoi Yang, 1997 from China; Proctorenyxa incredibilis (Kozlov) from Russian Far East. These are morphologically distinguished from other families of Proctotrupoidea families by the following combination of characteristics: antennal scape very short; vein Rs of fore wing not bifurcated apically; fore wing with pterostigma; gaster with narrow petiole; tergite 8 with two spiracles. And, the biology of this family is completely unknown. Here we report one unrecorded species, Proctorenyxa incredibilis (Kozlov, 1994), for the first time in Korea and provide photographs for the diagnostic characters.

Subfamily Ismarinae traditionally has been belong to the superfamily Proctotrupoidea, family Diapriidae. But recently, Sharkey (2007) has been placed family diapriidae in a separate superfamily of the infraorder Proctrupomorpha, the Diaprioidea, together with the New Zealand endemic Maamingidae and the cosmopolitan and speciose Diapriidae. After, subfamily Ismarinae is raised to family status Ismaridae stat. nov., also included the family Ismaridae within Diaprioidea (sharkey et al. 2011). The superfamily Diaprioidea Haliday, 1833 is a moderate large group of parasitoid wasps. Diaprioidea comprise five families (four extant family: Diapriidae Haliday 1833, Ismaridae Thomson 1858, Maamingidae Early, Masner, Naumann & Austin 2001 and Monomachidae Ashmead 1902; one fossile family Spathiopterygidae Engel & Ortega-Blanco 2013) of generally fairly small wasps, with a total of 2,109 species in the world. Family Ismaridae is a small family contains a single genus and 32 described species in the world and previously unrecorded in Korea. Ismaridae is morphologically distinguished from other families of Diaprioidea by the following combination of characteristics: antennae inserted close to the clypeus; position of toruli that are opening forward (not upward); notauli absent, with mesocutum broadly arched in lateral view; antennal formula 15-14. Also, the biology of this family is very poorly studied, only a few species known as hyperparasitoids of Auchenorrhyncha (Hemiptera) through dryinids (Hymenoptera). In this study, A new species, Ismarussp. nov. and one unrecorded species, Ismarus halidayi Foerster 1850, are reported from South Korea. Photographs of diagnostic characters are provided herein.

Earlier, Ceraphronoids group has been belong to the superfamily Proctotrupoidea sensu lato, as polyphyletic group. But, Masner and Dessart (1967) proposed this group as a separate superfamily, Ceraphronoidea to include Ceraphronidae and Megaspilidae. At present Ceraphronoidea comprised of two families with 27 genera and 603 species described worldwide (except fossil family Stigmaphronidae), though a great many species are still undescribed. This group is morphologically distinguished from other Hymenoptera superfamilies by the following combination of characteristics: two protibial spurs present; forewing C+Sc fused, Rs vein upcurved; metasomal segment II large; metasomal spiracles absent. Ceraphronoids are small group of Parasitic Apocrita of Hymenoptera. They majority are endoparasitoids of a wide range of insects under Diptera, Homoptera (superfamily Coccoidea), Hymenoptera, Lepidoptera, Neuroptera and Thysanoptera. However, Coleoptera, Diptera, Lepidoptera, Hymenopera, Neuroptera, Orthoptera, Heteroptera, spider eggs, and ticks are also attacked. And some species are hyperparasitoids of aphidiinae braconids. Ceraphronoidea has been studied in South Korea mainly by Paik (1994). He recognized the presence of only four species in Megaspilidae as follows: Dendrocerus carpenteri (Curtis, 1826), D. longispinus (Yasumatus & Moritsu, 1947), D. pupparum (De geer, 1776) and D. remicornis (Boheman, 1832). As a result of this study, 2 families and 2 genera of Ceraphronoidea, Ceraphron in Ceraphronidae, Conostigmus in Megaspilidae are recognized in South Korea. Also, above one family Ceraphronidae and all genera are newly recorded for the first time. We provide comparison of important diagnostic characters with two families and color photographs.

Rhyssinae Morley, 1913 is a relatively small group belonging to the family Ichneumonidae and recorded 286 species in eight genera from the world. Most rhyssines are Idiobiont ectoparasitoid of wood boring Symphyta and Coleoptera. South Korean Rhyssinae were poorly known. In the recent study of the Rhyssinae of South Korea, only four species belonging to the genera Megarhyssa and Rhyssa, have been reported: M. gloriosa (Matsumura), M. jezoensis (Matsumura), M. praecellens (Tosquinet) and R. persuasoria (Linnaeus). Five genera of the subfamily Rhyssinae (Epirhyssa, Megarhyssa, Rhyssa, Rhyssella and Triancyra) are recognized in South Korea. Two genera, Megarhyssa and Rhyssa, were previously recorded from South Korea, whereas the other three genera are recorded for the first time in Korea. A key to the five genera of Rhyssinae occurring in South Korea is provided. Genus Epirhyssa is reviewed here, and a key to the four species (E. latimandibularis (Hu & Wang), E. moiwana Matsumura, E. sapporensis Uchida and E. nigrithorax sp. nov.) is provided.
