Description.

Female. Fore wing length 2.8-2.9 mm. Head. Width of head (dorsal view) 2.0 × its median length. Transverse diameter of eye (dorsal view) 2.2-2.7 × longer than temple. OOL 1.7 × Od; POL 1.1 × Od; OOL 1.5 × POL. Longitudinal diameter of eye (lateral view) 1.5-1.6 × larger than its transverse diameter. Face medially not swollen, but with high complete medio-longitudinal carina; 1.6 × as wide as high. Longitudinal diameter of eye 2.7-3.1 × height of malar space (anterior view). Malar space 0.95-1.00 × base of mandible. Malar suture deep and smooth. Width of hypoclypeal depression 1.1 × distance from depression to eye. Antenna with 32-35 antennomeres, 1.0-1.1 × as long as fore wing. First, middle and penultimate flagellomeres 1.7-1.9 ×, 1.5-1.6 ×, and 1.7-1.9 × as long as wide, respectively. Mesosoma 1.5 × as long as high. Mesoscutum evenly setose. Propodeum with branching medio-longitudinal keel (in apical half only or complete) and at most with a weak medio-longitudinal impression basally. Wings. Vein r arising from basal 0.4 × of pterostigma. Vein 1-R1 1.6-1.7 × as long as pterostigma. Marginal cell 3.8-3.9 × longer than distance from its apex to apex of wing. Vein 3-SR 1.7-2.0 × than vein r, 0.36-0.42 × vein SR1, 0.9-1.25 × vein 2-SR. Vein 2-SR+M 0.33 × vein 2-SR, 0.5 × vein m-cu. Vein cu-a interstitial. Legs. Hind femur 3.6-4.9 × longer than wide. Fifth segment of hind tarsus 0.71-0.76 × as long as second segment and 0.39-0.41 × as long as hind basitarsus. Claws with acute angularly protruding basal lobe. Metasoma. Median length of T1 0.97 × its apical width; margin of its median area crenulate. T1 without dorsal carinae and sublateral posteriorly converging carinae; dorsolateral carinae of T1 weakly separated. T2 medially 0.94-0.97 × as long as third tergite. Basal width of T2 1.7 × its median length. Median area of T2 weakly elevated, triangle, elongate, weakly separated (no furrows). Anterolateral areas of T2 indistinct or weak, sublateral converging carinae absent. Dorsolateral impressions of T2 shallow, S-shaped, and weakly crenulated; spiracle located in middle of T2 near its lateral margin. Suture between T2 and T3 deep, curved, and crenulate. Apical margins of T3-T6 without transverse subapical grooves. Ovipositor sheath 0.80-0.85 × and 0.20-0.25 × as long as hind tibia and fore wing, respectively. Sculpture and colouration. T2 longitudinally rugose, T3-T5 rugose to granulate-rugulose. Body mainly pale yellow to yellow; antenna, ocellar triangle, patch on vertex, three patches on mesoscutum, and hind tarsus brown to dark brown; tegulae yellowish brown; pterostigma yellow or brownish yellow with brown patch apically; wing veins yellowish brown; wing membrane weakly darkened.

Male. Unknown.
