General body colour yellow with darker yellow-brown dorsally. Fore wing membrane clear or slightly fuscous basally.

Fore wing apex bluntly acute; surface spinules sparsely distributed, absent from r1 and c+sc; short to minute setae on margins and veins (Fig. 29A). Antennae short (length 0.75; ratio AL:HW 1.36); genal processes short (ratio VL:GP 3.50) and rounded apically; short to minute setae on vertex and thorax; distal proboscis segment short (length 0.09); hind tibia slender and longer than head width (ratio HW:HT 0.94) (Fig. 29 B–D, G). Female terminalia (Fig. 29 H–I): proctiger long, dorsal surface depressed posterior to anal ring and then more or less straight, apex acute, anal ring long (ratio FP:RL 2.68); subgenital plate with slight medial bulge ventrally, acute apically; ovipositor apex with very reduced serrations (2-3 above, 3 below), valvulae dorsalis moderately convex dorsally.

Egg.

Unpigmented to light brown, long and narrow, not sinusoidal, surface with broadly spaced longitudinal striations that are either continuous or interrupted, pedicel appears to be absent, tail lacking (Fig. 29 E–F).

Immature.
