Diagnosis (female). Antennal clava 3.5× as long as wide, with a constriction between C1 and C2 (Fig. 1012); genal carina present; mesoscutellum ( Fig. 106 ) with strong reticulation, meshes elongate in anterior two-thirds and isodiametric in posterior one-third, submedian grooves indistinct; propodeum with median carina very narrow, narrow part (i.e. excluding posterior expanded part) at least 6.0× as long as wide; hind coxa with a carina along posterior margin; dorsellum with median carina; gaster ( Fig. 106 ) 3.5× as long as wide, Gt 1 with weak reticulation and shiny, remaning tergites with strong reticulation and dull.

Female holotype: length of body 2.7mm (paratypes 2.6–3.2mm).

Scape yellowish-brown with dorso-apical part dark brown, pedicel and flagellum dark brown. Head with frons and vertex metallic bluish-green, clypeus dark brown, antennal scrobes black. Mesosoma golden-green. Legs with fore and mid coxae dark brown to black, hind coxa black with golden-green tinges; trochanters yellowish-brown; femora black with metallic tinges and with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 dark brown. Petiole black. Gaster with Gt 1 golden-green, remaining tergites black with metallic tinges; gonoplac black.

Antenna with a distinct constriction between C1 and C2. Face below level of antennal toruli and scrobes with weak reticulation, clypeal area smooth, above level of antennal toruli with strong reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric; midlobe without median groove, with six scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate in anterior two-thirds and isodiametric in posterior one-third, submedian grooves indistinct. Dorsellum with strong reticulation and shiny, with median carina. Propodeum with median carina very narrow in anterior half, strongly expanded and triangular in posterior half; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a strong carina along posterior margin. Fore wing with 3–4 setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster very elongate; medio-basal Gt 1 without edge or carina dorsally, this part smoothly rounded, with weak reticulation and shiny, remaining tergites with strong reticulation and dull.
