Diagnosis. Antennal flagellum yellowish-white, not flattened, scape narrow ( Figs 30–33 View Figs 30–35 ); pronotal collar without a carina along anterior margin ( Figs 30–33 View Figs 30–35 ); mesoscutum and mesoscutellum with strikingly different colours ( Figs 30, 32 View Figs 30–35 ); midlobe of mesoscutum without setae ( Figs 30, 32 View Figs 30–35 ); fore wing hyaline with area below stigmal vein weakly infuscate, narrow with a long marginal fringe, length of longest seta in marginal fringe/fore wing width = 0.6, and with speculum open below and towards base of wing ( Figs 2 View Fig , 30–32 View Figs 30–35 ); legs white, hind coxa infuscate at base ( Figs 31, 33 View Figs 30–35 ); male gaster dark brown with a white spot in anterior part ( Fig. 32 View Figs 30–35 ); length of body female 0.6–0.9mm, male 0.5–0.8mm.
Female holotype: length of body 0.9mm.
Antenna with pedicel and flagellum yellowish-white, scape pale brown. Frons with lower one-half dark brown, upper one-half metallic pale blue. Vertex metallic purple in anterior one-half, metallic blue in posterior one-half. Mesoscutum, dorsellum and propodeum metallic bluish-purple; mesoscutellum golden-red. Legs white, hind coxa infuscate at base. Fore wing hyaline with area below stigmal vein weakly infuscate, hind wing hyaline. Petiole black with metallic tinges. Gaster metallic bluish-purple with a large dark brown non-metallic median spot.
Antenna not flattened, scape narrow with dorsal and ventral margins ±parallel-sided. Frons with strong reticulation. Vertex with strong reticulation; with a short groove medio-posteriorly. Frontofacial suture V-shaped. Subtorular sutures present. Occipital margin rounded.
Pronotal collar without a carina along anterior margin. Mesoscutum with strong reticulation; notauli distinct almost throughout, missing close to mesoscutellum; midlobe without setae. Mesoscutellum flattened, with strong reticulation. Dorsellum convex with strong sculpture. Propodeum smooth and shiny; callus with two setae. Fore wing narrow with a long marginal fringe; speculum open below and towards base of wing; with a stigmal hairline and with radial cell bare.
Petiole very short, just a narrow band. Gaster short ovate; all tergites with strong reticulation.
