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.

Some more for Id.
