The length of the forewings is 18.5-25 mm for males and 22.5-27 mm for females. Adults are brightly coloured and can be distinguished from related Oreta liensis by the brownish red or pink coloration of the medial shade on the upper surface of both wings and by the conspicuous black and grey areas at the apex and the anal angle of the forewings.
