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.
