The moths reach a wingspan of 6 to 7 millimeters. The head is scaled close-fitting and has a dark brown sheen. He has a silvery white forehead ( frons ). The antennae are 3/4 as long as the fore wings. The labial palps are cylindrical and curved upwards. The thorax and tegulae are dark brown, the rear part of the thorax is yellowish white. The forewings are dark brown and lanceolate. They have two wide, yellowish white bands. The first bandage is near the base. It is wide on the inside of the wing and tapers abruptly on the Costa loader . The second band is 2/3 of the forewing length and tapers towards the inner wing edge. The fringed scales are ocher gray. The hind wings are very narrow and only about 1/3 as wide as the forewings. They are silvery white and have ocher-gray fringed scales. The abdomen is brownish gray and has a white tuft of anus .
In the male, the tegumen is narrow, ribbon-shaped and membranous. It is laterally sclerotized and tapers distally . The blades are slightly asymmetrical and have a broad basal part. They branch distally into a large ventral and a small dorsal lobe. They are wide in the basal half and taper sharply in the distal half. They are provided with long strong bristles. On the right valve there is a basal process that is covered with a patch of short, thick bristles and two rows of long bristles. In the distal part there is a small hairy lobe in front of the middle of the dorsal margin. The left valve has a similar lobe, but this is in the last quarter of the basal half. The aedeagus is long and bent at right angles. It tapers distally. Cornuti are not trained.
In the females the anal papillae are fused and severely sclerotized. The apophyses are long, strong, and about the same length. The ostium is very large and sack-shaped; it is offset to the left at the anterior edge of the seventh sternite . The ductus bursae is very narrow in front of the ostium and widens very sharply in the direction of the corpus bursae . The antrum is curved, it widens in the middle and is slightly sclerotized. The corpus bursae is rounded. The sign is large, elongated and forks.
