The length of the forewings is 19 mm for males and 21 mm for females. Adults closely resemble other species of the H. anicata clade. On average it is significantly larger than Hagnagora anicata, but the female has about the same size as Hagnagora hedwigae. It is easily distinguishable from Hagnagora marionae by the cream-white colour of the blotches on the forewing.
