    Thanks for the help, Dr Seow. Knowing the extent of variability will really help for future identifications; unfortunately there aren't many resources for the alea subgroup for comparison.

    sublustris seems quite variable ventrally.

    Shot this today. The two dorsals were taken hours apart but i think they're the same individual because of the way they're torn. The dorsal blue is quite muted (i didn't adjust the colours).

    The post-discal band on the forewing seems very strange to me. Probably either A. milleri or evansi? It was really shifty so i couldn't get good close-ups. C&P4 claims evansi has a pinkish wash but i find this really hard to judge

    It looks like you have the rare A. milleri.

    The upperside is described in C&P4 as a 'more matt darker indigo blue'. It is not totally non-reflective.
    I have seen a number of A. sublustrus uppersides & this is definitely not it.
    Most A. milleri have FW spot 9 in line with the band while in A sublusris it is more often shifted in.

    Another member recorded in Singapore is A. phanda
    The upperside is dark reflective blue & on the underside spot 6 & 7 are like a column.

    This one below from Langkawi should be A. evansi.

    Thanks for the confirmation, Dr Seow.

    Regarding this subgroup i have a few questions:

    1. Does it matter whether the post-discal band on the forewing is dislocated at vein 3?
    2. Does it matter whether spot 2 in the hindwing submarginal series(beside the tail) is shifted out, or how much it's shifted out?

    Seems like these two features are quite inconsistent

    1. I believed you mean vein 4 which the vein directly below spot 4.
    The only value stated is between A. cleander & athada ,where in cleander the band is usually continuous or slightly kinked, while in athada it is variously dislocated.

    2. This have no value.


    TL Seow: Cheers.

    Thanks Dr Seow. I was very baffled by the hindwing spot 2

    Perhaps it might be of some use.

    In most cases HW spot 2 is slightly or partially dislocated from spot 3.
    In A. phaenops it seem to be nearly more so.

    It may be a useful point of exclusion ID ie. if HW spot 2 is only partially or dislocated halfway from spot 3, it can not be A. phaenops.

    TL Seow: Cheers.
