Adult colour.

Typically bicoloured, generally pale yellow to green thorax and abdomen, head darker black or brown, and a dark dorsal stripe extending from head down the thorax. Fore wing membrane slightly fuscous.

Adult structure.

Fore wing apex bluntly acute; surface spinules dispersed, usually in all cells, but may be limited or absent from cells c+sc and r1; short setae on margins and veins (Fig. 13A). Antennae short (av. length 0.72; ratio AL:HW av. 1.38); genal processes extremely short and bluntly rounded (ratio VL:GP av. 3.27); short setae on vertex and thorax; distal proboscis segment moderately long (av. length 0.11); hind tibia slender, subequal or longer than head width (ratio HW:HT av. 0.95) (Fig. 13 B–C, F, I). Male terminalia (Fig. 13 D–E): paramere shorter than proctiger (ratio MP:PL 1.14), more or less parallel sided before tapering below dorsally flattened apex with bipartite sclerotization; distal aedeagus segment longer or subequal to paramere (ratio PL:AEL av. 0.91) with base angular and slightly inflated, and a large, broadly rounded, hooked apex (ratio AEL:AELH av. 2.30). Female terminalia (Fig. 13H): proctiger moderately long, dorsal surface more or less straight, apex acute, anal ring long (ratio FP:RL 3.41); subgenital plate long (ratio FP:FSP av. 1.48), with no or slight medial bulge ventrally, apex acute; ovipositor apex with reduced serrations (2 above, 2 below), valvulae dorsalis not strongly convex dorsally.
