Serratophyga Gen. n.

Type species: subangulata Warren, N.E. Himalaya.

This genus includes a few species that have been misplaced in Hypephyra Butler, a macariine genus. The male antennae are serrate and strongly ciliate, thus tending towards the Cassyma group of genera discussed first. The hindwing is slightly angled at M3. The facies resembles that of some Peratophyga species with a medial zone on both wings that is yellow, speckled and striated with blackish, bounded distally and basally by irregular black fasciae. The forewing postmedial has a sharp angle to it subcostally. The rest of the wings is dark grey. Below, the basal half of the wings is dull yellow, the distal half dark grey, resembling Hypephyra and a small basal grey patch on the forewing with Cassephyra.

The male genitalia have a typical dorsal process to the valve that is flexed centrally and has a short lateral spur subbasally. The ventral part of the valve is narrow, tapering, with a small central, semicircular flange. The uncus is triangular, with a produced, bifid apex. Coremata are not evident. The aedeagus apically has two longitudinal zones of spining, and the vesica has some scobinations distally. The valve shape is diagnostic for the genus.

The female genitalia have a broad, pyriform bursa that opens through a longitudinally placed ring of sclerotisation into the ductus. The ductus broadens to an obtusely notched ostium. The signum is modified into a crown-shaped flange.

The genus consists of the type species from the N.E. Himalaya, S. sterrhoticha Prout comb. n., described below, and S. xanthospilaria Wehrli comb. n. from S. China.
