Female. Length, excluding ovipositor, 1.30-1.89 mm. Head (Figs 61 View Figures 61–66 , 67 View Figures 67–72 ) yellowish brown to brown, mandible with three acute teeth. Antenna (Figs 62 View Figures 61–66 , 68 View Figures 67–72 ) brown to yellow, apex of clava relatively shallow. Mesosoma (Figs 63 View Figures 61–66 , 69 View Figures 67–72 ) yellowish brown, apical half of mesoscutum brown, scutellum yellowish white; fore wing (Figs 64 View Figures 61–66 , 70 View Figures 67–72 ) with apical two-thirds dark brown, basal third and hind wing hyaline (Figs 65 View Figures 61–66 , 71 View Figures 67–72 ); leg yellow (Figs 66 View Figures 61–66 , 72 View Figures 67–72 ), fore coxa, basal half of mid femora, basal third of mid tibial, hind coxa, and basal third of hind tibia white; frontovertex 0.26-0.33 × head width; eye height 1.67-2.38 × malar space; antennal scape 4.75-5 × as long as wide; pedicel 2.09-2.27 × as long as wide and longer than F1, funicle 6-segmented, clava 3-segmented, 2.72-2.96 × as long as width, longer than F4-F6 combined; fore wing 2.94-4.09 × as long as wide; linea calva not interrupted and open posteriorly; ovipositor 1.51-1.63 × as long as mid tibia, slightly exserted.

Variation.
