Description.

Female. Fore wing length 3.1-3.7 mm. Width of head (dorsal view) 1.9-2.0 × its median length. Transverse diameter of eye (dorsal view) 1.6-1.8 × longer than temple. OOL 2.0-2.9 × Od; POL 1.3-2.0 × Od; OOL 1.4-1.6 × POL. Longitudinal diameter of eye (lateral view) 1.5 × larger than its transverse diameter; hind margins of eye and temple subparallel. Face width 1.6-1.7 × combined height of face and clypeus. Longitudinal diameter of eye 2.3-2.6 × longer than malar space (anterior view). Malar suture absent. Width of hypoclypeal depression 1.0-1.2 × distance from depression to eye. Antenna 0.55-0.75 × as long as fore wing, with ca. 24 antennomeres. First, middle and penultimate flagellomeres 1.6-2.3 ×, 1.6-1.9 ×, and 1.6-1.9 × longer than wide, respectively. Mesosoma about 1.4 × longer than its maximum height. Mesoscutum evenly, but sparsely setose. Notauli weakly impressed and not united posteriorly. Medio-longitudinal keel developed in apical third of propodeum, simple. Fore wing vein r arising from basal 0.45-0.48 × of pterostigma. Vein 1-R1 1.3-1.4 × longer than pterostigma. Marginal cell 2.5-4.5 × longer than distance from its apex to apex of wing. Vein 3-SR 1.3-1.7 × vein r, about 0.35 × vein SR1, 0.90-0.95 × vein 2-SR. Hind femur 4.2-4.3 × longer than wide. Fifth segment of hind tarsus 0.45-0.48 × as long as hind basitarsus and about 0.8 × as long as second segment. Claws protruding triangular basal lobes. First metasomal tergite without dorsal and dorsolateral carinae, its median length 0.7-0.9 × its apical width. Second metasomal tergite without median area and dorsolateral impressions; medially 1.0-1.2 × longer than third tergite; its basal width about 1.9-2.0 × its median length. Second metasomal suture deep, curved and crenulate. Apex of ovipositor with weak nodus and weak ventral serration. Body mostly granulate; submedian longitudinal stripes on mesoscutum smooth; second tergite anteromedially granulate-rugulose. Body mainly brownish black with reddish yellow pattern on head, mesoscutum and legs; maxillary palp brown; wing membrane brownish darkened, pterostigma brown with yellowish patch basally, wing veins brown.
