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.
