similiar species:

exprimens Walker has extreme mauve highlights, particularly at the margins of the wings, that define a diagnostic brown semicircle at the anterior half of the forewing margin and emphasise the smoother, less angular submarginal on the hindwing. The hindwing angle is much more produced in costristriga.
