    Default ID Correction.

    Oops!
    The upperside shows a tiny spot in space 5 not seen in P. natuna.(upperside spots are all hyaline.)

    So this should be P. helena female.

    TL Seow:Cheers.
    PS A female P. natuna for comparison.

    Wow, if confirmed would be the first record of this species for Thailand!

    It is just beside the faint white spot on the inside.
    In contrast the same area in P. natuna is plain orange.

    The 2nd ID clue is that the veins in P. helena are yellow & in P. natuna orange-yellow.
    This become apparent when the two are placed side by side.

    The two were once considered as one species but has since been separated.
    It is quite probable that field shots of P. helena are routinely ID'ed as P. natuna.
