both wings are closer to the margin in the female.
Taxonomic note. The most easterly member of this group is P. cythera Swinhoe
comb. n. from Fiji.
Geographical range. Borneo.
Habitat preference. The holotype male is from the low-lying southern
Bornean island of Pulo Laut. A female has been taken subsequently by S. J. Willott
