Features
The moths reach a wingspan of 26-28 millimeters, and have dark brown forewings. The midfield is bounded on both sides by thick black transverse lines, however, do not extend to the front edge. The midfield is strongly narrowed toward the inner edge. The black scale bar at the apex is often associated with the outer boundary of the central field. The hind wings are brownish, not brightened at the wing leading edge and carry a significant black middle transverse line and more numerous indistinct transverse lines. Both wings have a barely broken hemline.
