A very small Prosotas species photographed in Phayao province, northern Thailand.
I can only make this Prosotas lutea, but the generally buff colouration and the shape of some of the discal bands are dissimilar to my other photos.

In all photos I have seen, the outer discal band of the forewing has a "V" shape in the middle formed by the two central marks. This is not the case here.
Is this still Prosotas lutea? Some seasonal variation?
Many thanks

TL Seow: Cheers.

PS. On 2nd thought it could also be the female of P. bhutea.
Males & female. P. bhutea ID. No spot below midcell band in space 1b (if FW is raised high enough to see ) ;more faded marginals & submarginals.

Female Prosotas bhutea. (most likely )

The bands in Prosotas nora female are fairly strongly margined in dark & white striae.

Female P. bhutea. bands narrower & the white striae are rather poor.

Many thanks for this. Indeed P. bhutea was my second guess for this individual.
