(Figs 124–126)  
 Diagnosis. Antenna flattened, scape widest at apex (Fig. 124); pronotal collar without a carina along anterior margin (Figs 125, 126); midlobe of mesoscutum with four pairs of setae (Fig. 125); midlobe of mesoscutum and median part of mesoscutellum black with golden-purple tinges (Fig. 125); fore wing infuscate with two hyaline areas, one below marginal vein and one subapical (Figs 124, 126); hind tarsus with T1–3 white, T4 dark brown (Fig. 124); length of body female 1.1–1.3mm.   
Female holotype: length of body 1.3mm.  
 Antenna dark brown. Frons golden-green. Vertex metallic bluish-purple in anterior one-half, metallic blue in posterior one-half. Mesoscutum with midlobe black with golden-purple tinges, sidelobes metallic bluish-purple. Mesoscutellum black with golden-purple tinges, lateral parts metallic bluish-purple. Dorsellum metallic purple. Propodeum golden-purple. Coxae, femora, mid and hind tibiae dark brown; fore tibia with basal one-half dark brown and apical one-half infuscate; fore tarsus infuscate, mid and hind tarsi with T1–3 white and T4 dark brown. Fore wing infuscate with two hyaline areas, one below marginal vein and subapical; hind wing hyaline. Petiole dark brown. Gaster with Gt 1,6 metallic purple, Gt 2 dark brown with sides metallic purple, remaining tergites dark brown with metallic tinges.   
Antenna flattened, scape widest at apex. Frons with strong reticulation; frontofacial suture V-shaped. Vertex with strong reticulation. Subtorular sutures present. Occipital margin rounded.  
Pronotal collar without a carina along anterior margin. Mesoscutum and mesoscutellum with strong reticulation; notauli distinct in anterior one-half; midlobe of mesoscutum with four pairs of setae. Dorsellum convex with weak reticulation. Propodeum smooth, without median carina; callus with two setae. Fore wing speculum closed; with a stigmal hairline and bare radial cell.
