Diagnosis. This species is mostly similar to Goniozus japonicus Ashmead, 1904 by having mandible yellow; by fore wing without areolet; by flagellomere 3–5 longer than wide respectively; by propodeal disc with complete transverse carina; by ratio of head and propodeal disc. However, this species can be distinguished from G. japonicus by short antennal segments, by pedicel to flagellomere 2 less than 1.5 × as long as wide, by flagellomere 11 1.5 × as long as wide (long antennal segments, pedicel to flagellomere 2 longer than 2.0 × as long as wide, flagellomere 11 2.0 × as long as wide in G. japonicus ); by median and submedian cell of fore wing with relatively denser hairs (very sparse hairs in G. japonicus ).

Description. FEMALE (holotype). Body length 4.1 mm. LFW 2.5 mm.

Color. Head: mandible yellow, antenna yellow, from flagellomeres 6–11 pale castaenous. Mesosoma black; fore wing subhyaline, veins pale castaenous; legs yellow except coxa and femora dark castaenous, tarsal claw dark castaenous. Metasoma black except distal margin of terga 4–7 pale castaenous.

Head ( Figs 18–20 ): 1.0 × as long as wide, coriaceous; lateral margin convex, posterior margin straight, postero-lateral corner forming round angle in dorsal view; lateral surface smooth and polished. Mandible with four acute teeth. Clypeus well-developed, frontal angle right; fronto-clypeal median longitudinal carina developed, exceeding antennal socket. First antennal segment in ratio of 2.3: 1.0: 1.0: 1.1: 1.2 in length; from scape to flagellomere 3 and 11 2.0, 1.3, 1.2, 1.2, 1.3 and 1.6 × as long as wide, respectively. Frons and vertex coriaceous with sub-erect hairs and sparse moderate punctures, aparted from each other 2.0–3.0 × as wide as their maximum diameter. WF 1.1 × LE, WF 0.6 × WH. Compound eye 0.37 mm long without hairs. LE 1.8 × OOL, WF 1.7 × WOT. Frontal angle of ocellar triangle obtuse, POL 2.1 × AOL, OOL 0.8 × WOT. Vertex coriaceous without conspicuous long hairs.

Mesosoma ( Figs 21–23 ): Pronotum coriaceous, 0.4 × 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 pit elliptical, oblique and connected by 3.9 × 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 mid-length of disc, connected to transverse carina with thin longitudinal carina in areolate surface. Disc areolate-rugose; declivity coriaceous with complete marginal carina; lateral surface coriaceous. Fore wing without closed areolate; median and submedian cell with two rows of hairs; radial vein curved outward at apex with obtuse angle; pterostigma 0.29 mm long; metacarpo absent.

Metasoma ( Fig. 24 ): Tergite 1 smooth and polished without fine puncture and microreticulation. Terga 2–4 smooth and micoreticulation on anterior half with some hairs on dorso-lateral surface. Terga 5–7 microreticulate with sparse hairs on distal surface.

MALE. Unknown.

Distribution. Korea (Busan, CB, CN, Daejeon, GB, GG, GN, GW, JB, JJ, JN, Seoul).
