    Default Tanaecia munda. Could it still be extant in Singapore?

    The identification of the three Tanacia, pelea, munda and palguna can be very difficult in fieldshots.
    Both T. pelea and munda have forms in which the HW can be brown or strongly whitened.

    The seperation of T. pelea is not based on its appearance but that the 3rd segment of the palpi are long and needle-like.
    This only holds true in P. Malaysia as in other places eg Java, T pelea have the palpi 3rd segments short.

    T. munda have been recorded in Singapore before with a typical male in the Museum.

    T. munda have the palpi 3rd segment about half the length in pelea.

    Typical T. pelea in Singapore.
    Males.

    The observation.

    This female looks to be a whiter, T. pelea but zooming in at the head end only the bulging palpi 2nd segments can be seen clearly, suggesting the 3rd segments to be rather short.

    It is not the female Euthalia monina which have the large FW space 1b sub-basal spot broken into two small dark spots.
    eg,

    A side view would easily solve its identity.

    It appears that there are T. pelea in Pulau Ubin with extensive white on both wings.
    This male below have the long needle-like palpi of T. pelea.

    The stated observation is likely to be another T. pelea.
