Diagnosis (female). Antenna with a weak constriction between C1 and C2 (Fig. 763); with a weak genal carina; mesoscutellum (Fig. 306) with submedian grooves strong and diverging towards posterior part, median part with strong reticulation, and with median groove indicated; dorsellum with a weak but complete median carina; propodeum (Fig. 306) with strong irregular carinae and strong reticulation, callus with three setae; petiole transverse with strong sculpture on dorsal part; gaster (Fig. 306) 2.1× as long as wide; fore wing (Fig. 307) with two infuscate spots, one spot around and below stigmal vein and one weaker spot at upper-apical margin of fore wing; body dark brown to black with weak metallic tinges (Figs 306, 307). Male with C2 enlarged (Fig. 964), and with same infuscate spots in fore wing as female.
Female holotype: length of body 1.7mm (paratypes 1.4–1.7mm).
Scape yellowish-brown, pedicel and flagellum dark brown. Head dark brown to black. Mesosoma black. Legs with fore and hind coxae black, mid coxa dark brown; trochanters pale brown; femora dark brown; tibiae yellowish-brown, hind tibia with basal one-third brown; T1–3 yellowish-brown to yellowish-white, T4 brown. Wings hyaline with one infuscate spot below stigmal vein and one spot on apicodorsal margin. Petiole black. Gaster dark brown to black; gonoplac black.
Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with a weak genal carina. Vertex with strong reticulation; with a carina between posterior ocelli in posterior part.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove in posterior half, with eight adnotaular setae in two rows. Mesoscutellum with strong reticulation, meshes elongate; with median groove indicated; submedian grooves distinct, straight and diverging slightly towards posterior part; with three setae on lateral parts. Dorsellum with weak sculpture, with median carina. Propodeum with a wide median carina that expands in posterior part, this part concave; with strong irregular carinae and strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
