Antenna slightly flattened, scape widest at apex (Fig. 96); flagellum with F4–5 paler than remainder of antenna (Fig. 96); pronotal collar without a carina along anterior margin (Fig. 95); mesoscutellum with weak reticulation and 0.9× as long as wide (Fig. 95); major part of midlobe of mesoscutum and scutellum golden-red (Fig. 95); fore wing hyaline with area below stigmal vein infuscate (Fig. 95); hind tarsus yellowish-brown (Fig. 95); length of body female 0.8–1.2mm, male 0.6–1.0mm.   
Female holotype: length of body 1.2mm.  
 Antenna with scape, pedicel and F1–3 dark brown, F4–5 infuscate. Frons golden-green. Vertex metallic blue in anterior one-half, golden-green in posterior one-half. Mesoscutum with midlobe golden-red, sidelobes metallic blue. Mesoscutellum golden-red with lateral and posterior margins golden-green. Dorsellum metallic bluish-green. Propodeum golden-green medially and metallic bluish-purple laterally. Legs with coxae, femora, mid and hind tibiae dark brown, fore tibia white with base brown; fore tarsus infuscate, mid and hind tarsi yellowish-brown. Fore wing hyaline with area below stigmal vein infuscate; hind wing hyaline. Petiole dark brown. Gaster with Gt 1,6 metallic blue, Gt dark brown with sides metallic blue, Gt 7 dark brown.
