This should be correct as P. iswaroides female.
I do not have an image of a female P. iswaroides for comparison.

Judging from the more prominent pale FW stripes this should be a female.
p. iswaroides is redaily Ided by the underside with a lack of most of the submarginal red lunules except for the two at the tornus.
