    Probably correct as Potanthus trachala. Correction: Potanthus pseudomaesa.
    FW spots 4 & 5 fully detached from the others.

    Three species may be rather similar.

    P. trachala have narrow markings; Spot 2 & 3 strongly concave margins in the male.
    Males.

    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.

    Correction ;Potanthus pseudomaesa.

    There are examples of P. pseudomaesa in which FW spots 4 & 5 are detached.
    In fact Evans states this for P. pseudomaesa.


    The other fact is P. trachala always have a HW spot 7, often prominent.
    HW spot 6 is usually absent or at most vestigial.

    P. Malaysia
    http://nlliew66butterflies.blogspot....-trachala.html

    Spots normally have strongly concave margins but can be variable.


    P. pseudomaesa is usually without a HW spot 7 above (variable).
    Spot 6 is more often present.
    Spots 2 & 3 only have the margins less concave.
    The abdominal end black mark is more bandlike in P. trachala.
    P. pseudomaesa with spots 4 & 5 fully detached.
