    1. Yes , Flos areste is right.

    This & A. adriana are very similar .The area where the tail is ,is torn off.

    Flos areste :Tailless;FW postdiscal band outer margin stepped (90 degree).
    HW apical area dark-shaded to the margin in space 5, 6, & a bit of 7.

    A. adriana:Tailed. FW postdiscal band with a sharp notched (80 degree) at vein 5.
    HW apical area not noticeably darkened.
    Dark shading largely in space 5 & not reaching the apical margin.

    3. Probably Arhopala bazalus, very worn.
    The FW band appear very broad but that is due to some mark outside the band.
    FW band is dislocated at vein 4.
    FW cellspots with some metallic highlight.
    HW spot 6 strongly notched on the outside . spot 5 also appeared to be notched.
