( Figs 20, 21 View Figs 20–24 , 205 View Figs 205–213 )
Diagnosis. Antenna flattened, scape widest just below apex ( Fig. 21 View Figs 20–24 ); pronotal collar without a carina along anterior margin ( Fig. 20 View Figs 20–24 ); midlobe of mesoscutum with one pair of strong setae ( Figs 20, 21 View Figs 20–24 ); fore wing hyaline with an infuscate band below stigmal vein, reaching to hind margin (but there almost hyaline), stigmal vein elongate ( Figs 20, 21 View Figs 20–24 , 205 View Figs 205–213 ); length of body female 1.8mm.
Female holotype: length of body 1.8mm.
Antenna dark brown. Frons golden. Vertex metallic bluish-green. Mesoscutum and mesoscutellum metallic bluish-green. Dorsellum metallic bluish-purple. Propodeum metallic purple. Coxae, femora and tibiae dark brown; fore tarsus dark brown, mid and hind tarsi with T1–3 pale brown, T4 dark brown. Fore wing hyaline with an infuscate band below stigmal vein, reaching to hind margin (but there almost hyaline), hind wing hyaline. Petiole dark brown. Gaster metallic bluish-green.
Head (collapsed and frons difficult to see): Antenna flattened, scape widest just below apex. Frons and vertex with rather strong reticulation; frontofacial suture difficult to see but possibly straight. Subtorular sutures present but difficult to see because they are dark. Occipital margin rounded.
Pronotal collar without a carina along anterior margin. Mesoscutum and mesoscutellum with strong reticulation; notauli indistinct; midlobe with one pair of strong setae. Dorsellum weakly convex, with weak reticulation. Propodeum without median carina, with weak reticulation; callus with two setae. Fore wing with speculum closed; without stigmal hairline but with radial cell bare; stigmal vein elongate.
Petiole very short, just a narrow band. Gaster elongate.
Relative measurements: head length dorsal 13.5; head length frontal 19; head width 33; POL 7; OOL 4; lateral ocellus maximum width 2.5; eye length 13.5; malar space 5; mouth width 10; mesosoma length 39; mesosoma width 29; mesoscutellum length 18; mesoscutellum width 17.5; fore wing length 71; fore wing width 46; marginal vein length 40; postmarginal vein length 2.5; stigmal vein length 9.5; fore wing marginal fringe length 3.5; gaster length 52; gaster width 26.
