Diagnosis. The wings are a dull pale brown, the hindwings with a small pale discal
spot ringed darker brown to black, often intensely as in the Bornean specimen
illustrated. Confusion with P. contrariata Walker is possible but contrariata
is more emphatically fasciated, and the hindwing discal spot is larger,
white as well as black.
Taxonomic notes. The male fourth sternite has coremata. The uncus is very broadly bilobed. The valve ornamentation is costal, broad. There are coremata basal to
the genitalia.
Geographical range. Indo-Australian tropics east to Queensland, Fiji, but
not New Caledonia.
Habitat preference. Two Bornean specimens have been seen, both from areas
of disturbed and secondary forest: Labi in Brunei and Brumas in Sabah.
Biology. Yunus & Ho (1980) recorded Derris (Leguminosae) as a
host-plant in Malaysia.
