Description

Male. Length of fore wing: 17.5– 18 mm. A little larger than previous two species. Head pale brown, antenna bipectinate. Wings ochreous-grey, lines black. Fore wing with basal and terminal areas a little darker, central part paler; antemedian line very oblique, not waved, weakly curved near inner margin; discal spot relatively small, irregularly shaped, slightly produced outwards at upper and lower angles; postmedian line oblique and nearly straight from costa to M 3, forming a small angle at M 3 and then running outwards again to Cu 1, where it forms a very sharp angle and turns back, deeply curved, to inner margin. Hind wing more uniformly coloured, with white-centred discal spot incompletely ringed with black; postmedian line almost same shape as on fore wing, with longest tooth on Cu 1, not on M 3 as in other species; short black bars running outwards from postmedian on veins, especially Rs, M 1, M 3 and Cu 1. Underside whitish pink, with barely visible shadow of upperside lines; fore wing with discal spot in the form of a double streak and anterior half of postmedian line dark purplish; a dark patch before apex on costa.

Male genitalia ( Figure 61 View Figures 61–64 ). Socii broad at base, curving outwards to a narrow point. Small uncus present between socii. Valva narrow, a little curved ventrally at middle. Terminal part of basal lobe of valva shaped like a crow’s head, with the beak very sharply pointed. Saccular process narrow but strongly sclerotized, with three or four huge spines on the terminal part. Aedeagus relatively small.

Female. Unknown.
