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.
