Pariaconus liliha Percy sp. n. Figure 14

Adult colour.

Typically bicoloured, generally pale cream-yellow to green thorax and abdomen, head darker, with a dark dorsal stripe from the head extending part or all the length of the body. Fore wing membrane fuscous.

Adult structure.

Fore wing moderately narrow, apex bluntly acute; surface spinules distributed in all cells, but limited in c+sc; short setae on margins and veins (Fig. 14A). Antennae short (av. length 0.75; ratio AL:HW av. 1.47); genal processes extremely short and bluntly rounded (ratio VL:GP av. 4.58); short to minute setae on vertex and thorax; distal proboscis segment short (av. length 0.07); hind tibia subequal or shorter than head width (ratio HW:HT av. 1.13) (Fig. 14 B–C, F, K). Male terminalia (Fig. 14 D–E): paramere shorter that proctiger (ratio MP:PL 1.18), broad at base and tapering to narrow neck below rounded apex with interiorly directed hook; distal aedeagus segment length subequal to paramere (ratio PL:AEL av. 1.03) with base angular and not inflated, and a broadly rounded, hooked apex (ratio AEL:AELH av. 2.20). Female terminalia (Fig. 14 G–I): proctiger short, dorsal surface convex apically, apex bluntly rounded, anal ring extremely long (ratio FP:RL 1.98); subgenital plate extremely short (ratio FP:FSP av. 1.48), with slight medial bulge ventrally, apex truncate; ovipositor apex with shallow serrations (2 above, 2 below), valvulae dorsalis strongly convex dorsally (Fig. 14I).
