10mm. This species is very similar to angustifascia and purifascia in facies, but the male has distinctly female features such as: shorter, less upcurved labial palps, the third segment tapering rather than tufted; absence of a subcostal flap on the forewing underside. The pale bands on the wings are narrower than in angustifascia, that of the forewing ending more distantly from the costa. The male abdomen has a more strongly developed framed corematous eighth segment, the frame to the sternite less flimsy, more structured, broader and shallower, but with the same type of single, shallow corema. The valves have a basal corema that is not present in the other species, and, more distally, they appear distinctly doubled. Their bases are well separated, rather than touching, and the saccular process is more conspicuous, robust. The juxta is broader, with less of a V-shaped ridge towards its apex.
