Description & Diagnosis. Wingspan 27–29 mm. Forewing crossed by straight, greyish-white bands, the distal two (postmedial and submarginal) lined blackish, basal and antemedial lines acutely angled near costa. Wing surface otherwise dark brown. Hindwings with a white, curved postmedial line without dark borders, veins black. L. witzenmanni has very similar pattern elements, but he wing surface between the lines is rather light grey instead of brown (Fig. 8). Male genitalia (Fig. 39) with broad, distally truncate valves, provided with elongate, distally curved harpes and straight, rather short, finger-shaped dorsal arms; strong, tooth-shaped projections are arising internally from the bases of the harpes; juxta broad, elongate, distally notched. Female genitalia with corpus bursae broad and spiculate; diverticulum of bursa present.
