Description
On the obverse, the wings are dark brown. The forewings have a series of submarginal yellow dots and a few yellow macules at the apex. The hindwings have tails and bear a postdiscal row of macules, yellow in the male and white in the female, and a red dot in the anal angle. The reverse side is very similar but the hindwings bear two additional red dots and blue disc lunulae.P. caiguanabus has a peculiar appearance owing to the absence of the yellow discal bands and the enlargement of the submarginal spots.
