The wingspan is about 12 mm. The forewings are light rosy-purple-brownish with about eight small blackish costal marks and an irregular brown mark on the fold towards the base, terminated by a few blackish scales, and edged with some whitish suffusion. There is a narrow oblique brown fascia from before the middle of the costa to beyond the middle of the dorsum, partially edged with blackish posteriorly. A streak of brown suffusion runs from the middle of the disc to the middle of the termen, including a line of black scales, and edged above posteriorly by a fine white streak. The hindwings are grey.[4]
