( Figs 2–5 View FIGURES 2 – 5 , 56 View FIGURES 56 – 68 )
Diagnosis. Midlobe of mesoscutum with posterior ½ smooth except for a few strong foveae ( Fig. 4 View FIGURES 2 – 5 ) and with posterior 2/3 of notauli as row of pits; frontal suture reaching eyes below anterior ocellus at a distance equal to 1.5X diameter of an ocellus ( Fig. 2 View FIGURES 2 – 5 ); forewing costal cell bare (as in Fig. 52 View FIGURES 47 – 53 ); propodeum smooth, callus with 4 or 5 setae.
Description. FEMALE. Length 0.8–1.7 mm. Antenna dark brown. Frons below frontal suture golden-green; above frontal suture metallic purple. Vertex golden-green with dark brown parts inside ocellar triangle, outside dark brown. Mesoscutum metallic bluish-green. Scutellum with anterior ½ metallic purple, posterior ½ metallic bluish-green. Propodeum metallic bluish-purple. Coxae dark and metallic; femora and tibiae dark brown; tarsi with tarsomeres 1–3 white, 4 dark brown. Forewing hyaline. Gaster dark brown with metallic purple, blue and green tinges.
Antenna as in Fig. 56 View FIGURES 56 – 68 . Frons smooth below frontal suture close to scrobes and close to eyes ( Fig. 2 View FIGURES 2 – 5 ), but with raised, strong reticulation between the smooth areas and with raised, weak reticulation above frontal suture; frontal suture reaching eyes below anterior ocellus at a distance equal to 1.5X diameter of an ocellus. Vertex with raised, rather strong reticulation ( Fig. 3 View FIGURES 2 – 5 ) except smooth lateral to posterior ocelli. Occipital margin rounded. Eyes with sparse, scattered hairs ( Figs 2, 3 View FIGURES 2 – 5 ).
Pronotum without transverse carina close to posterior margin ( Fig. 4 View FIGURES 2 – 5 ). Mesoscutum with raised, weak reticulation ( Fig. 4 View FIGURES 2 – 5 ), midlobe with posterior ½ smooth except for a few strong foveae; notauli as narrow distinct grooves in anterior 1/3, and as row of pits in posterior 2/3. Scutellum with raised, weak reticulation ( Fig. 4 View FIGURES 2 – 5 ) except median, lateral, and posterior parts with very weak reticulation to smooth; with 1 pair of setae. Propodeum smooth ( Fig. 5 View FIGURES 2 – 5 ); callus with 4 or 5 setae. Forewing speculum closed below; costal cell bare.
Petiole 0.2X as long as wide, smooth. Gaster ovate with apex acuminate; tergites smooth.
MALE. Unknown.
