I initially thought it could be a Baoris but after comparing many images online, the wingshape doesn't seem quite right. Baoris seems to have a more prominently lobed hindwing. The angle is slightly deceiving. I've attached another shot taken at a somewhat more parallel angle showing that the forewing is not as bowed as it appears in the first shot. Never managed to get parallel because it was very easily spooked.
Also, the white spots are bothering me because they seem so variable. The checklist shows one with very faint spots while there are others elsewhere with spots more developed and i don't know which ones to trust!
