Description & Diagnosis. Wingspan 22–25 mm. Forewings brownish grey, darker distally, hindwings a little lighter, both without pattern. Underside like upperside (Fig. 30). The similar, but larger and darker grey L. flavicornata is also clearly distinguishable by the genitalia. Male genitalia (Fig. 56) with valves narrow, sclerotized costa very short, with a very large, triangular projection. Harpe with a long, upright, distally curved process, dorsal arm strong, stout, with long spines terminally. Aedeagus long, narrow, straight. Female genitalia (Fig. 75, holotype) characterized by trapezoid, posteriorly concavely rounded sterigma, with inserted triangular ostium orifice; ductus bursae tubular, corpus bursae globular, completely spined internally, large diverticulum present.
Bionomics. Specimens studied are collected in May and June at altitudes of 1000–1800 m.
Additional data on distribution based on literature sources. Falkovitsh (1986): Uzbekistan; Prout (1937 – 1939): Karaj (Tehran prov.).
Distribution. S Russia to Armenia and N Iran; distribution areas in southern Uzbekistan and western Tajikistan probably disjunctive (Map 7).
