    I think you are confusing the HW apical spot with the FW spot.

    Ignoring the FW spot.
    Uemura states in Y. confusa HW apical spot (ie spot 6 (in space 6))is much larger than spot 2 ( spot in space 2).
    The 3rd spot is in space 1b.
    HW without a dark fascia.

    Y. watsoni: HW apical spot variably larger than spot 2 or about equal. HW with a dark discal fascia.

    Y. akbar ;HW with dark faciae, no or vestigial spots.

    It should be Ypthima watsoni.

    Dear Dr Seow,

    Could this be a Y. akbar? I shot it at Chiang Doi over a year ago but could not ID it. Thanks.
