    Default An interesting, aberrant Arhopala

    Found this very timid Arhopala today which never allowed an easy shot. It was quite small, the size of A. abseus and seems aberrant; the forewing post-discal band is completely missing.

    However, the character that stood out to me is the dislocated hindwing post-discal band at vein 2, which means this is quite likely A. avathina avathina.

    Thoughts?

    Agreed it is very likely A. avathina.

    Intrestingly Fleming also list A. kurzi in Singapore.
    This also have the HW postdiscal band widely dislocated at vein 2.
    It would seem A. kurzi have a tendency for the 'V' spot to be broken into two.

    Thanks, Dr Seow. I originally thought it was an aberrant muta/moorei but decided not because of the spot arrangement.

    I attach another shot from a different angle, this time with vein 2 obscured. I increased the contrast so that the spots are more visible. Would you still consider this avathina?

    Here's the holotype for A
    Arhopala avathina from Singapore.

    I would still be hesitant to place Aaron's Arhopala as this species are it is just a little to worn to discern the main diagnostic features..

    I thought the Singapore Biodiversity site have only the upperside image in my search.

    With a proper underside this doesn't match.

    C&P4 states in A. avathina the postdiscal band is completely dislocated at vein 2, not dislocated widely as here.
    The green metalmark is large & elongate & also does not match.

    The closest it come to is A. hypomuta.

    Thanks everyone for all the input. I shall just leave this as "cf. muta" since its exact ID will probably never be determined.

    Dr Seow, the one in the wiki link seems misIDed; it should be muta
