Diagnosis (female). Antennal clava with a distinct constriction between C1 and C2 (Fig. 1040); genal carina present; mesoscutellum (Fig. 192) with complete submedian grooves, reticulate with slightly elongate meshes; hind coxa with a carina along posterior margin; gaster (Fig. 192) 2.2× as long as wide, medio-basal Gt 1 without transverse edge or carina dorsally, Gt 1 with weak reticulation and more shiny than remaining tergites.

Female holotype: length of body 2.4mm.

Scape yellowish-brown with dorsal edge brown, pedicel brown, flagellum dark brown. Face below level of toruli greenish-blue, clypeus dark brown, frons black with golden-purplish tinges, antennal scrobes black; vertex black with purple tinges. Mesoscutum black with golden-purple tinges; mesoscutellum with median part metallic bluish-purple and lateral parts black with golden-purple tinges; propodeum golden-green. Legs with coxae black; trochanters and femora dark brown to black; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster dark brown to black with metallic tinges; gonoplac black.

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

Mesoscutum with strong reticulation, meshes mainly isodiametric but elongate in posterior half of midlobe; midlobe without a median groove, with seven scattered adnotaular setae. Mesoscutellum with strong reticulation, weaker on median part, meshes slightly elongate; submedian grooves weak but traceable, 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 strongly in posterior part; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin. Fore wing with five setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole transverse. Gaster ovate-elongate; tergites with strong reticulation, medio-basal Gt 1 without transverse edge or carina dorsally, with weaker reticulation and more shiny than remaining tergites.
