Mesosoma black; fore wing subhyaline, veins castaenous; legs pale castaenous except coxa and femora dark castaenous, tarsal claw dark castaenous. Metasoma black except distal margin of each tergite subhyaline.
Head (Figs 10–12): 1.1 × as long as wide, coriaceous; lateral margin convex, posterior margin straight, postero-lateral corner forming round angle in dorsal view; lateral surface polished. Mandible with four acute teeth. Clypeus well-developed, frontal angle of clypeus right; fronto-clypeal median longitudinal carina developed, exceeding antennal socket. First antennal segment in ratio of 1.9: 1.0: 1.1: 1.1: 1.0 in length; from scape to flagellomere 3 and 11 1.9, 1.5, 1.7, 1.5, 1.4 and 1.9 × as long as wide. Frons and vertex coriaceous with sub-erect hairs and sparse small punctures, aparted from each other by 2.0–5.0 × as wide as their maximum diameter. WF 1.0 × LE, WF 0.6 × WH. Compound eye 0.40 mm long without distinct hairs. LE 2.0 × OOL, WF 1.7 × WOT. Frontal angle of ocellar triangle obtuse, POL 2.0 × AOL, OOL 0.9 × WOT. Vertex coriaceous without conspicuous long hairs.
Mesosoma (Figs 13–15): Pronotum coriaceous, 0.5 × as long as wide with sparse hairs, antero-lateral corner obtuse. Mesoscutum coriaceous; notauli absent; parapsidal furrows thin and anteriorly divergent. Scutellum polish and coriaceous with sparse small punctures; scutellar pits oval, oblique and connected by 3.8 × as wide as their maximum diameter. Propodeal disc 0.6 × as long as wide, lateral and transverse carina complete; medial basal triangle smooth and polished, extending beyond mid-length of disc, connected to straight transverse carina with smooth median thin carina in areolate surface. disc areolate-rugose; declivity coriaceous with complete marginal carina; lateral surface coriaceous. Fore wing without closed areolet; median and submedian cell with sparse hairs; radial vein curved outward at apex; pterostigma 0.21 mm long; metacarpo absent.
Metasoma (Fig. 16): Tergite 1 smooth and polished without fine puncture and microreticulation. Tergite 2 polished with anterior one third coriaceous and some short hairs on lateral surface. Terga 3 to terminal with anterior two thirds coriaceous and sparse hairs on distal half surface.
MALE. General shape as in female, but ocelli larger and strongly produced; POL: AOL=3:1; OOL 0.5 × WOT (Terayama, 2006).
Distribution. Korea (CB, CN, Daejeon, GB, GG, JB, JN), China (Taiwan), Russia (South of Khabarovskii Krai, South of Primorskii Krai, South of Yakutia), Japan (from Honshu to South Ryukyus).
Remarks. This species widely is distributed in Far Eastern Asia and known as ectoparasitoid against for Gelechiidae, Gracillariidae, Pyralidae, and Torticidae in Japan (Terayama, 2006).
