( Figs 43 View Figs 35–43 , 94, 95 View Figs 92–95 , 1001)

Diagnosis (female). Antennal clava solid (Fig. 1001); genal carina absent; mesoscutellum ( Fig. 94 View Figs 92–95 ) with strong reticulation, meshes elongate, submedian grooves indistinct but traceable, slightly curved, wide apart and diverging towards posterior part; hind coxa without carina along posterior margin; propodeum ( Fig. 94 View Figs 92–95 ) with a strong median carina that expands gradually towards posterior part; gaster ( Fig. 94 View Figs 92–95 ) 3.3× as long as wide, medio-basal Gt 1 with a rectangular incision.

Female holotype: length of body 2.1mm (paratypes 2.2–2.3mm).

Scape yellowish-brown, pedicel and flagellum dark brown. Head golden-green, antennal scrobes black, clypeus dark brown. Thoracic dorsum golden-green. Legs with fore and mid coxae black, hind coxa golden-green; trochanters pale brown; femora black with metallic tinges; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1-2 golden-green, Gt 3-5 golden-purple, Gt 6-7 golden-green; gonoplac black.

Antenna with solid clava. Face below level of toruli with weak reticulation, clypeus smooth, frons with strong reticulation, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, slightly elongate on midlobe; midlobe without median groove, with eight setae ±in one row close to notauli. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct but traceable, slightly curved, wide apart and diverging towards posterior part. Dorsellum with strong sculpture. Propodeum with a strong median carina that expands gradually towards posterior part; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with carina along posterior margin. Fore wing with four setae on dorsal surface of submarginal vein; speculum open towards base of wing; costal setal row unbroken.

Petiole transverse. Gaster elongate; medio-basal Gt 1 with a rectangular incision, and with weak reticulation and shiny, remaining tergites with strong reticulation.
