(Figs 46–48)  
 Diagnosis. Antenna flattened, scape widest at apex (Fig. 48); pronotal collar with a carina along anterior margin (Fig. 46); midlobe of mesoscutum with three pairs of setae (Fig. 46); midlobe of mesoscutum and mesoscutellum with median part dark (golden-purple), contrasting against lateral parts (Fig. 46); fore wing hyaline with three infuscate parts: along apical margin, below stigmal vein, and below marginal vein (Figs 46–48); hind tarsus with T1 and T4 dark brown, T2–3 white (Fig. 48); length of body female 1.3–1.8mm, male 1.1mm.   
Female holotype: length of body 1.8mm.  
 Antenna dark brown to black. Head with frons golden-green; vertex metallic purple. Mesoscutum with midlobe with median part golden-purple, lateral parts and sidelobes metallic bluish-purple. Mesoscutellum with median part golden-purple and lateral parts metallic bluish-purple. Dorsellum metallic purple. Propodeum with median part golden and lateral parts black. Coxae and femora black with metallic tinges; fore tibia pale brown with base dark brown, mid and hind tibiae black with metallic tinges, fore tarsus brown, mid and hind tarsi with T1 and T4 black, T2–3 white. Fore wing hyaline with three infuscate parts: along apical margin, below stigmal vein, and below marginal vein, hind wing hyaline. Petiole hidden in type specimen (dark brown in paratype). Gaster with Gt 1 and Gt 6 metallic purple, remaining tergites golden.   
Antenna flattened, scape widest at apex. Frons and vertex with strong reticulation. Frontofacial suture V-shaped. Subtorular sutures present. Occipital margin rounded.  
Pronotal collar with a carina along anterior margin. Mesoscutum with strong reticulation; notauli distinct in anterior ¾; midlobe with three pairs of setae. Mesoscutellum convex, with strong reticulation. Dorsellum convex and smooth. Propodeum with weak reticulation, without median carina; callus with two setae. Fore wing speculum closed; with a stigmal hairline and with radial cell bare.
