Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 (Fig. 1026); genal carina present; mesoscutellum ( Fig. 144 ) with strong reticulation, meshes elongate, submedian grooves indistinct, wide apart, slightly curved and diverging towards posterior part; hind coxa without carina along posterior margin; gaster ( Fig. 144 ) 2.3× as long as wide, Gt 2 0.4× as long as Gt 4, medio-basal Gt 1 with a ±rectangular incision, with very weak reticulation, distinctly more shiny than remaining tergites.

Female holotype: length of body 2.2mm (paratypes 1.7–2.1mm).

Scape yellowish-brown, pedicel and flagellum dark brown. Head metallic bluish-green, clypeus dark brown, antennal scrobes black. Thoracic dorsum metallic bluish-green. Legs with coxae black with blue-green tinges; trochanters and femora dark brown to black, femora with metallic tinges; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 metallic bluish-green, remaining tergites black with purple tinges; gonoplac black.

Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with seven setae in one row close to notauli. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct, wide apart, slightly curved and diverging towards posterior part; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with strong reticulation. Propodeum with a strong median carina that expands in posterior part, expanded part concave; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation, hind coxa without carina along posterior margin. Fore wing with four setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster elongate; medio-basal Gt 1 with a ±rectangular incision, with weak reticulation and shiny, remaining tergites with rather strong reticulation.
