South Korea (new record). Description. Female. Fore wing length 2.7-3.7 mm. Width of head (dorsal view) 1.7-1.9 x its median length. Transverse diameter of eye (dorsal view) 1.5-1.7 x longer than temple. OOL 2.4-2.8 x Od; POL 1.6-2.0 x Od; OOL 1.4 x POL. Longitudinal diameter of eye (lateral view) 1.4-1.6 x its transverse diameter; hind margins of eye and temple subparallel. Face width 1.5-1.6 x combined height of face and clypeus. Face width 1.9-2.4 x larger than width of hypoclypeal depression. Longitudinal diameter of eye 2.9-3.5 x longer than malar space (anterior view). Malar suture absent. Width of hypoclypeal depression 1.2-1.6 x larger than distance from depression to eye. Antenna 0.84-0.90 x as long as fore wing, with 25-27 antennomeres. First, middle and penultimate flagellomeres 1.9-2.3 x , 1.5-2.2 x and 1.7-2.2 x longer than wide, respectively. Mesosoma 1.4-1.6 x longer than its maximum height. Mesoscutum setose on notaulic area, with sparse setae medio-longitudinally. Notauli very deep anteriorly, impressed and not united posteriorly. Mesepimeral and metapleural sulci smooth. Medio-longitudinal keel developed in apical third of propodeum, branching. Fore wing vein r arising from basal 0.40-0.45 of pterostigma; vein 1-R1 1.5 x longer than pterostigma; marginal cell 7-9 x longer than distance from its apex to apex of wing; vein 3-SR 2.5-2.9 x vein r, 0.55-0.70 x vein SR1, 1.3-1.6 x vein 2-SR. Hind femur 3.9-4.4 x longer than wide. Hind tibia with 2 thick setae subapically. Fifth segment of hind tarsus 0.45-0.50 x as long as hind basitarsus, 0.90-0.97 x as long as second segment. Claws with acute angularly protruding basal lobe. First metasomal tergite with incomplete dorsal carina and developed dorsolateral carinae; its median length 0.80-0.93 x its apical width. Second tergite without median area and with very shallow s-shaped weakly crenulate dorsolateral impressions not bordered by carinae; medially 1.0-1.2 x longer than third tergite; its basal width 1.7-2.0 x its median length. Second metasomal suture deep, curved and crenulate. Apical margins of third to sixth tergites thick, with weakly foveate transverse subapical grooves. Ovipositor sheath 1.3-1.4 x longer than hind tibia, 0.37-0.41 x as long as fore wing. Apex of ovipositor with weak nodus and distinct ventral serration. Body mainly smooth; frons, face, and malar space granulate; first tergite posteriorly rugose; second tergite laterally longitudinally rugulose, anteromedially rugose to rugulose; third tergite granulate-rugulose to weakly granulate; fourth-sixth tergites weakly granulate to smooth. Body mostly brownish black; legs and lateral sides of metasoma reddish brown; maxillary palps, basal half of hind tibia, and metasoma ventrally pale yellow; tegulae brownish yellow; wing membrane weakly darkened, pterostigma and veins brown.
