Posting this for a friend. A dart photographed around Chiang Mai.

I think it is correct as Potanthus nesta female. (the black 'hole' in the FW cell bar ID'ed the female.)
The FW band is continuous but the veins are lightly darkened ;HW upperside veins not darkened.
Underside with heavy black markings.

Below link. pic 1 looks correct as P. nesta male but pic 2 is P. confucius male.
The others uncertain.

P. confucius looks similar but band more continuous with veins less dark ;Underside less black shadings & abdominal end not black banded.
Female.
