    Thanks Dr Seow!

    I'm also seeking your opinion on the following Rapala.

    Could this be Rapala damona? Searching through the web and other online platforms does seem to show that R. damona has a larger filling at space 1b compared to R. suffusa.

    Thank you!

    Yes. This is a Rapala damona male.

    The large speckled patch is particularly significant in Sundaland..Sumatra, Malaya, Java & Borneo.
    These examples are from the Andaman islands north of Sumatra.

    You can also check Otsuka 's specimens in the Borneo Lycaenids.
    You can download it here.

    The examples from continental Asia have a smaller speckled patch about 60 - 70 % coverage.

    Do not simply accept images from website.
    Try to cross check if you can.
    Many errors occur.

    Rapala damona is one.
    This example from northern Thailand is Rapala dieneces, not R. damona.
    The HW 's upper third is largely black.

    PS. Helpful features.
    If the HW speckled patch is small & the postdiscal line/band is angled sharply it is always R. suffusa.
    Female.

    The postdiscal band is rounded above the speckled patch is rounded in R. damona & dieneces.
    R. damona female.

    Post 61,
    Yes. This is a female T. colon.

    Normally in T. colon FW spots 4 & 5 are distorted in shape & in the male they are not aligned, ie spot 5 is farther out from spot 4.
    This is not so obvious in the female.
    In female FW spot 5 is often bisected horizontally as seen here.
    The general appearance is as in T. besta female but besta female have spots 4 & 5 equal & not distorted.

    T. colon male & female.
