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.

The subfamily Lycorininae Cushman & Rohwer, 1920 is a small group with a single genus, Lycorina. This subfamily can be easily distinguished from other ichneumonids subfamilies by the following characters: impreesed triangular pattern on the metasomal tergites, tergite 2-4 with convex central triangular area; hypopygium of female large and triangular in lateral view, centrally membranous and with small median apical notch. Genus Lycorina is a cosmopolitan genus with 30 described species (Yu et al., 2012). Also, from this genus have been reported five species in Eastern Palaearctic region, six species from China, two species from Japan and one species for the first time from Korea. The focal host range appears to be weakly concealed larva of micro-lepidopteran species. Some species have been reared from Crambidae in leaf-rolls or webs (Doerksen & Neunzig, 1974; Finlayson, 1976) and Tortricidae (Chao, 1980; Shaw, 2004). In this study we report one newly recorded to Korea species, Lycorina triangulifera Holmgren, 1859 and provide the diagnosis and photographs.

The genus Pristomerus Curtis, 1836 is one of among 36 genera belonging to the subfamily Cremastinae. This genus is a large genus with 100 worldwide species distributed (Yu et al., 2012). Also, from this genus have been reported 15 species in Eastern Palaearctic, eight species from China, seven species from Japan and three species from Korea. Subfamily Cremastinae is known as koinobiont endoparasitoids of solitary larval-pupa mostly Lepidoptera and Coleoptera (Fitton & Gauld 1980). Spectrum of host species of Pristomerus include various small Lepidoptera living in tunnels, leaf rolls, buds and other hidden areas (Rousse et al., 2011). Genus Pristomerus can be easily distinguished from other genera by the following characters: hind femur with ventral tooth; deep gastrocoelus on tergite II. Three species from this genus, Pristomerus chinensis Ashmead, 1906, P. erythrothoracis Uchida, 1933, and P. vulnerator (Panzer, 1799), have been reported from Korea previously. In this study we report three newly recorded species, Pristomerus rufiabdomenalis Uchida, 1928, P. parilis Kusigemati, 1984, P. kendarensis Kusigemati, 1984, and described three new species. Here we provide the descriptions and photographs of six species of genus Pristomerus, and species key.

The genus Xorides is a large group xoridine genus was firstly described by Latreille in 1809 based on Ichneumon indicatorius. The world fauna of Xorides have comprised of 147 described species(Yu et al., 2005). Among them, 48 species have distributed in Eastern Palaearctic region(Yu et al., 2005) and only one species, Xorides jezoensis, was recorded from Korea (Uchida,1955). Most species are specialized parasitoids of eight coleopteran families (Anobiidae, Bostrichidae, Buprestidae, Cerambycidae, Chrysomelidae, Curculionidae, Elateridae, Melandryidae), three hymenopteran families, two lepidopteran families, one dipteran family(Yu et al., 2005). Also, emerge from larva as ectoparasitoids(Sharifi & Javadi, 1971) and idiobiont(Chrystal & Skinner, 1931). This genus is similar to genus Odotocolon but mandible without two teeth; female flagellomere curved with peg like setae. In this study, we found two newly recorded species, Xorides konumensis(Uchida, 1928) and Xorides sapporensis(Uchida, 1928) from Korea.

The genus Eriborus which is a small-sized campoplegine genus was firstly described by Föster in 1869 based on Campoplex perfidus. Members of this genus included 52 species in the world. Among them, 11 species are distributed in Eastern Palaearctic region, and only two species, E. molestae (Uchida, 1933) and E. terebrans (Gravenhorst, 1829) have been recorded in Korea(Yu et al., 2005). Most species of this genus are specialized parasitoids of 17 lepidopteran families, Cerambycidae(Coleoptera) and Tenthredinidae(Hymenoptera), and more particularly attack most of Noctuidae and Pyralidae(Lepidoptera) larvae as koinobiont endoparasitoids. This genus is easily distinguished from other campoplegine genera by the combination of the following characters: Carinae of propodeum usually strong, areola longer than wide; propodeal spiracles circular or short elliptic; fore wings without areolet; thyridium subcircular or longitudinally elliptic. In this study, we found two newly recorded species, Eriborus vulgaris (Morley, 1913) and Eriborus sinicus (Holmgren, 1868) from Korea. A revised key to the species of Korean Eriborus Föster, redescriptions and photographs of diagnostic characters are provided.
