    Likely to be Allotinus unicolor.

    Although the markings look somewhat different it is the arrangement that matters.
    On the HW postdiscal spot 6 is the slightly 'S' shaped spot (not the diamond-shaped one).
    This spot 6 is placed well inside of spot 7 (a vertical bar) & spot 5.
    The position is diagnostic for A. unicolor only.

    UnH with the white stria merging with the orange patch in space 2.

    See below female from Nan.

    Underside shading variable & bands edged with dark spots.
    HW spot 6 not large above.
