A rather small (2.2 – 2.7 cm wingspan) broad-winged moth. The forewing is marbled with yellow-brown, red-brown and dark grey-brown. Both the antemedian and postmedian lines are doubled, outlined in dark and filled with pale scales. Orbicular round, yellow-brown, reniform large and filled with light grey or brown with a prominent dark spot on the dorsal side. Terminal area and fringe dark brown, almost black. Hind wings light grey-brown, darkening toward the outer margin, with light brown fringe. Head and collar dark brown, contrasting with lighter thorax and tegulae. Sexes similar.
