( Figs 135 View Figs 130–136 , 141, 142 View Figs 137–142 , 214 View Figs 214–223 , 225 View Figs 224–232 , 235 View Figs 233–238 )
Diagnosis. Antenna flattened, scape widest at apex ( Figs 142 View Figs 137–142 , 225 View Figs 224–232 ); upper frons with an edge separating it from vertex ( Fig. 235 View Figs 233–238 ); pronotal collar with a carina along anterior margin ( Fig. 141 View Figs 137–142 ); mesoscutum and mesoscutellum with very weak reticulation and shiny ( Fig. 141 View Figs 137–142 ); midlobe of mesoscutum without setae ( Fig. 141 View Figs 137–142 ); fore wing infuscate with basal one-half and two subapical spots hyaline, speculum open below ( Figs 142 View Figs 137–142 , 214 View Figs 214–223 ); hind tarsus with T1 infuscate, T2–4 white ( Fig. 142 View Figs 137–142 ); petiole as long as wide; gaster circular ( Fig. 141 View Figs 137–142 ); length of body female 1.4–1.7mm, male 1.1mm.
Female holotype: length of body 1.6mm.
Antenna dark brown to black. Frons golden-green. Vertex metallic bluish-purple. Mesoscutum metallic bluish-green with posterior one-half of midlobe golden-red. Mesoscutellum metallic blue with anteromedian one-half golden-red. Dorsellum metallic bluish-purple. Propodeum metallic purple. Coxae, femora and hind tibia dark brown; fore and mid tibiae infuscate; fore tarsus infuscate, mid tarsus white, hind tarsus with T1 infuscate, T2–4 white. Fore wing infuscate with basal one-half and two spots close to apical margin hyaline; hind wing hyaline. Petiole black. Gaster with Gt 1-2 metallic bluish-purple, remaining tergites dark brown.
Antenna flattened, scape widest at apex. Frons with strong reticulation; frontofacial suture Vshaped; part above suture with distinct margin separating it from vertex. Vertex with strong reticulation in anterior one-half, posterior one-half with very weak reticulation, partly smooth. Subtorular sutures missing. Occipital margin with an edge behind ocellar triangle.
Pronotal collar with a carina along anterior margin. Mesoscutum and mesoscutellum with very weak reticulation and shiny; notauli distinct in anterior one-half; midlobe of mesoscutum without setae. Dorsellum convex and smooth. Propodeum with a median carina in posterior two-thirds, otherwise smooth; callus with two setae. Fore wing speculum open below; with a stigmal hairline and with radial cell bare.
Petiole as long as wide, with strong sculpture on dorsal surface. Gaster circular.
