A couple of Potanthus from northern Thailand

These two individuals are from 1,100 m, on Doi Suthep, north Thailand.

I have tried to narrow down these two, but as usual with Potanthus skippers it's a headache with some features fitting but others not.

The first two images are the same individual, and I think it is P. mingo - but could be pava, nesta or omaha)? There appears to be no black veins on the spots of the hindwing.

The third image I think is P. omaha?

Any comments gratefully received. With thanks.

They are probably Potanthus mingo.

An UnH is always helpful.

The folowing have the abdominal end yellow or merely with a thin black line in the male.
They can be eliminated.
They are, P. omaha, ganda, pava, confucius.
