The female have spots with straight margins & look very similar to P. pallida, but the veins on the HW band are less prominent.

The black patch at the abdominal end in your photo is like that of P. pseudomaesa but the markings are closer to P. trachala.


P. sita looks similar but has yellow markings & spots usually with slight overlaps.
