    Default ID help please : Potanthus sp. ?

    Dear Dr Seow,
    Can i ask for your help with the following ID ? Location : West Sumatra - Indonesia.
    These are 3 different sightings, but they look very similar so I think they are the same species.
    Thanks for your help.

    The antennal club is rounded at the end without an apiculus , the extended tip.

    This identifies it at once as Taractrocera.

    Pic 1 is male from the abdominal end .
    Pix 2 & 3 are females.

    There are only a few species.
    The male of T. archias & nigrolimbatus have continuous conjoined FW banding.
    T. ardonia have pale spots & a large rounded head of the HW band.

    This leaves T. luzonensis (formerly as T. ziclea)

    The Sumatran ssp tissara have narrower markings.

    ID: Taractrocera luzonensis tissara.


    T. luzonensis luzonensis in the Philippines for comparison.
