Thank you a lot for your help. Now I know where and what to look for to id these difficult group of species, but still far from being confident. So, here are some more which I think are Potantus, requesting for your help.
But before that, if you could tell how to differentiate between Potanthus, Telicota and Oriens. Maybe too basic, but because of pandemic, I am stuck in a place without my books on butterflies.
10 a, b, & c.
Probably Potanthus mingo.
The FW spots 4 & 5 have continuous but minimal overlaps above & below.
HW upper end project out prominently & there is a spot 6.
There is a great similarity to P. pseudomaesa but this have the spots 4 & 5 typically just detached above & minmally overlap spot 3 below.
Both are the same species.
Variants probably Potanthus nesta ?female.
FW band continuous overlap but less uniform with slight vein darkening.
HW band upper part barely project, with the inner margin almost level ie just a slight shallow step.
Well with the variation of P. nesta as shown below.
Females of species such as P. cofucius & pava have the FW band less continuous than the male. http://yutaka.it-n.jp/hes/92800001.html
Thank you for all these help, its been really great. Its like a gold mine of yellow skippers. Never paid much attention to them as they are difficult to id. But now, with your help, they have become really interesting, and will be looking for them in the field.
I have few more of Telicota and Oriens which I would like to share, maybe in a new thread.
