( Figs 108, 109 , 885 , 1015)

Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 (Fig. 1015); with a short genal carina close to mouth opening; frons below toruli with two ovate, deep and strongly reticulate foveae ( Fig. 885 ); mesoscutellum ( Fig. 108 ) with strong reticulation, meshes slightly elongate, without median groove; propodeum ( Fig. 108 ) with a strong median carina, sides parallel in anterior half, strongly expanding backwards from middle of propodeum; hind coxa with a carina along posterior margin; gaster ( Fig. 108 ) 2.4× as long as wide, medio-basal Gt 1 with a rectangular incision.

Female holotype: length of body 2.2mm.

Scape yellowish-brown with dorsal edge dark brown, pedicel and flagellum dark brown. Face below level of toruli with weakly reticulate parts golden-green and strongly reticulate parts metallic blue; frons metallic blue, antennal scrobes black, clypeus dark brown; vertex black with metallic purple tinges. Mesoscutum and mesoscutellum metallic bluish-green; dorsellum and propodeum golden-green. Legs with fore and hind coxae metallic bluish-green, mid coxa black with metallic tinges; trochanters dark brown; femora black with metallic tinges and with apex yellowish-brown; fore and hind tibiae dark yellowish-brown, mid tibia pale brown; fore tarsus pale brown, mid and hind tarsi with T1–3 yellowish-brown, T4 dark brown. Petiole black. Gaster with Gt 1 golden-green with posterior margin black, Gt 2-5 with median part golden-purple and lateral parts metallic blue, Gt 6 golden-green, Gt 7 black; gonoplac black.

Antenna with a weak constriction between C1 and C2. Face below level of toruli with weak reticulation except two ovate, deep and strongly reticulate foveae just below toruli, clypeal area smooth, frons rugose, antennal scrobes with strong reticulation; with genal carina. Vertex with strong transverse wrinkled sculpture.

Mesoscutum with strong reticulation, meshes ±isodiametric on both mid- and sidelobes; midlobe without a median groove, with seven setae in ±one row close to notauli. Mesoscutellum with strong reticulation, meshes slightly elongate, without median groove; submedian grooves weak, curved, running parallel and close to lateral margin of mesoscutellum. Dorsellum with strong reticulation. Propodeum with a strong median carina, sides parallel in anterior half, strongly expanding backwards from middle of propodeum; 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 four setae on dorsal surface of submarginal vein; speculum slightly open below, with setae missing at base; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a weak rectangular incision, with weak reticulation and more shiny than remaining tergites, Gt 2-7 with strong reticulation.
