ADULT DESCRIPTION AND VARIATION

Wingspan: 62--90mm. Larger and more brightly coloured than Cypa decolor; anal angle of forewing more pointed than in that species. In the male, forewing upperside with large creamy postdiscal patch; underside with postdiscal line not prominent. Hindwing cinnamon-red with a blackish submarginal band. Abdomen with black stigma-dots. Thus similar in appearance to Smerinthulus dohrni, but hindwing upperside with a blackish shadowy postdiscal band.

In the male genitalia, uncus broad, constricted at base and in middle, with apex divided into two short pointed lobes. Gnathos with small medial element the apex of which is undivided. Valve with apex excavated and produced into a large spine-like process; basally with two sharp, long teeth and a smaller tooth below these; ventrally folded and with a boot-shaped process above fold. Aedeagus lacking armature. In the female genitalia, tergum A8 crescent-shaped, apical margin strongly rounded. Sterigma large, distal margin emarginated with angles rounded. Ostium bursae proximal and with a low ridge before it.
