A correction. Counting the basal thin line or band in , the bar to be noted should be bar 5.

Confoundingly similar to P.philota and probably others. Some examples of philota have the marginal area of the fwing faded and the markings obscure. However note bar 4 in the costal half of the fwing. If the bar is whole or intact it is sumatrae; if broken into small spots it is philota; and if it is merely divided it is uncertain.
