features
The moths reach a wingspan of 18 to 20 millimeters, according to another source from 13.5 to 16.5 millimeters. The maxillary palps are triangular and blackish. The labial palps are short and inconspicuous. The head and thorax are blackish brown, speckled with scanty white. The metathorax is provided with a pair of white drawing, the abdomen is white striped. The forewings are brownish black and speckled with short narrow white scales. The drawing consists of four white, irregularly curved and angled transverse lines that are equidistant from one another and more or less parallel to the outer edge. A pair of small white spots lies distal to the black discal spot , three or four more spots are distributed in the middle field. The fringed scales are irregularly blackish brown and piebald white. The hind wings are colored just like the fore wings. The basal half - with the exception of the veins - is whitish and has a black discal spot. The outer white cross tie is curved and jagged. A white subterminal line is indicated in the area of the anal angle . The fringed scales are colored just like those of the forewings. The undersides of the wings are white and mottled blackish along the veins and in the subterminal area. The outer transverse band is white and jagged on the fore and hind wings. There are scattered white spots in the subterminal area. The hemline is black, the fringed scales are irregularly piebald.
In the males, the uncus is quite short and strong. It has a rounded tip and is slightly hairy. The Gnathos is dagger-shaped and tapers sharply. The tip has short, papilla-like teeth. The blades are short, have a broad base and are hairy. The clasper is missing. The phallus is short and thick. In the distal part there is an elongated group of fairly large cornuti. Distal to this is a second, almost round group of small cornuti arranged in rows.
In females, the corpus bursae is almost spherical and has a tower-shaped bulge from which the ductus bursae arises. The Signa are inconspicuous. The ductus bursae is quite wide, the colliculum is narrowed at both ends. The antrum is narrow, funnel-shaped and heavily sclerotized .
