Description.

Female. Fore wing length 2.6-3.0 mm. Width of head (dorsal view) 1.7-1.8 × its median length. Transverse diameter of eye (dorsal view) 1.6-2.0 × longer than temple. OOL 2.0-2.8 × Od; POL 1.2-1.8 × Od; OOL 1.6-1.7 × POL. Longitudinal diameter of eye (lateral view) 1.3-1.6 × its transverse diameter; hind margins of eye and temple subparallel. Face width 1.4-1.5 × combined height of face and clypeus. Longitudinal diameter of eye 3.1-3.3 × longer than malar space (anterior view). Malar suture weak under eye, smoothed near mandible. Width of hypoclypeal depression 1.2-1.4 × distance from depression to eye. Antenna 0.90-0.95 × as long as fore wing, with 24-25 antennomeres. First, middle and penultimate flagellomeres 2.0-2.1 ×, 1.7-2.0, and 1.8-2.2 × longer than wide, respectively. Mesosoma 1.7-1.8 × longer than its maximum height. Mesoscutum evenly, but sparsely setose. Notauli deep anteriorly, shallow 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 1.5-1.7 × longer than pterostigma; marginal cell 12-16 × longer than distance from its apex to apex of wing; vein 3-SR 2.0-2.5 × vein r, 0.55-0.65 × vein SR1, 1.3-1.4 × vein 2-SR. Hind femur 3.0-3.4 × longer than wide. Hind tibia without subapical row of thick setae. Fifth segment of hind tarsus 0.50-0.55 × and 0.95-1.00 × as long as hind basitarsus and second segment, respectively. Claws with acute angularly protruding basal lobe. First metasomal tergite with incomplete dorsal carina and developed dorsolateral carinae, its median length 0.70-0.85 × its apical width. Second tergite with weak, narrow, longitudinal median area, weak anterolateral areas with smooth sculpture, and with deep s-shaped crenulate dorsolateral impressions bordered by long carinae; medially 1.1-1.5 × longer than third tergite; its basal width 1.3-1.8 × its median length. Second metasomal suture deep, curved and crenulate. Apical margins of third-sixth tergites thick, with weakly foveate transverse subapical grooves. Ovipositor sheath 0.85-1.00 × as long as hind tibia and 0.23-0.25 × as long as fore wing. Apex of ovipositor with weak nodus and ventral serration. Body mainly smooth; face medially and malar space granulate, face laterally and frons weakly granulate; propodeum posteriorly hardly coriaceous, with tree-like rugosity medially in posterior half; first metasomal tergite smooth to weakly foveate; second tergite areolate-rugose to foveate; third-sixth tergites smoothed foveate, or metasoma entirely areolate-rugose to foveate-rugose. Head and mesosoma mostly reddish brown with yellowish brown pattern, legs and lateral and ventral parts of metasoma reddish yellow; antenna basally reddish yellow, flagellum darkening apically; maxillary palps yellow; tegulae brownish yellow; propodeum and most of metasoma dorsally dark brown; wing membrane weakly darkened, pterostigma and veins brown.
