    Default Nacaduba berenice?

    Is this a Nacaduba berenice? The N.berenice had not been recorded in my Habitat before. Only the N.calauria and N.kurava had been recorded previously.

    It is Prosotas, probably Prosotas nora.

    Prosotas (except P. aluta) lacks the costal spot above the cellend bar. ( Sometimes a vestigial dot is present.) Also lowest spot of the FW postdiscal band is usually shifted in ; peripheral spots not marked in white (except P. aluta.).


    However there is a very strong suggestion this is Prosotas pia pia.

    Typical P. nora have the submarginal & marginal marks or spots equally dark or at least the submarginal spots are darker.Best compare on the HW.
    There are very good examples of this species in Singapore.
    Males.

    This male does not look the same as the typical males nora from Singapore.

    Furthermore, a mating pair taken years ago in Singapore have the orange female with the HW submarginal spots faded off much as in the female P. pia.

    TL Seow: Cheers.
    PS. Nacaduba berenice icena males for comparison.
    Note FW postdiscal band's lowest spot not shifted in; marginal & submarginal spots strongly defined by white striae ; three costal spots.
