    Thank you so much Dr. Seow

    Our friend from Bhutan seeks help for another specimen. Both the images below are probably of the same individual according to him.

    Could this be identified?

    Post 25.

    This would be fairly typical for Pseudoborbo bevani.
    There are a lot of mixed up with the two species , that sometimes it is difficult to tell which is right.

    Pseudoborbo bevani.
    More golden brown ;FW typically one cellspot; spot 2 & 3 more rounded ;spot in space 1b poor or absent.
    UnH with the spots not sharply defined.
    Antennal with more prominent pale area.

    Typical examples.
    Taiwan.

    Borbo cinnara
    Darker grey brown above.
    FW with 1-2 cellspots, sometimes none. ; spot 2 & 3 irregular, 2 is crescentic; spot 1b is always prominent in both sexes.
    UnH with the spots typically well-defined.
    Antennal pale area obscure or absent.

    One doubt Dr. Seow

    Many people consider this as one of the id pointers for B.bevani. Do you think it is valid?

    spot 3 in UPF to be more nearer to spot 2 than to spot 4.

    In other words distance between spot 3 & 4 is more than that between 2 & 3

    The statement is true & valid but caution in interpreting a field shot.

    In P. bevani ,spot 3 is distinctly nearer spot 2 than spot 4 (Note spot 4 sometimes may be absent.)
    http://yutaka.it-n.jp/hes/93070001.html

    In B. cinnara FW spot 3 is only a little bit nearer spot 2 than spot 4, & may be appeared almost equidistant from both.
