Pterocyclophora Hampson

Type species: pictimargo Hampson, Sri Lanka.

All species are strikingly patterned, with moderate sexual dimorphism as in the Bornean representative. The forewings are pinkish or reddish fawn apart from a lens-shaped pale (males) or dark (females) grey marginal area. The hindwings are a dull yellowish fawn with an irregularly shaped black and grey border. The underside is yellowish fawn, speckled with black; there are three incomplete, anteriorly divergent black bands on the forewing that recur weakly on the hindwing as more regular fasciae that curve parallel to the margin but are partially obscured by a broader band of black and grey running between the two more exterior ones. The margins are dentate at the veins, with a small tail on the hindwing at vein M3.

In the male, the dorsal zone of the wing is compressed, with a lobe on the margin exterior to a small submarginal fovea. A similar lobe is present in
Daddala quadrisignata. The male antennae are bipectinate, also those of the female, though to a lesser extent. 

Features of the male abdomen support the suggestion of a relationship to Daddala, particularly to quadrisignata. The eighth segment is even more complex but has comparable lateral pleated processes. The structure of the genitalia is similar, but the valves are shorter, more ovate, and the saccus is longer.

The female genitalia has the ostium associated with the eighth segment, inserted in the ventral gap of the ring. The ductus is short, the bursa basally rather bulbous, with a fluted neck that tapers to a slight constriction before expanding into a pyriform, unsclerotised distal section. The ductus is relatively shorter and the bursa larger than in
D. quadrisignata.

The genus consists of a largely allopatric array of species that ranges throughout the Indo-Australian tropics. In addition to the type species and the one described below, there is hampsoni Semper in the Philippines, an undescribed species in Sulawesi, huntei Warren in Seram, New Guinea and Australia, and albiapicata Warren in the Solomons.
