Description & Diagnosis. Wingspan 29–31 mm. Wing pattern: a pale grey reminiscent of that in L. amoenata, also quite similar to the next two species; postmedial line most conspicuous, curved outwards two times, rather close to termen; ground colour of both wings darker grey; hindwings without pattern, dark grey (Fig. 11). Male genitalia with short, broadly rounded valves and a strong, thorn-shaped harpe arising from its centre; dorsal arm slender, without apical spines, diverging from valve costa; saccus short, triangular; aedeagus short and stout (Lehmann et al., 2009). Male genitalia are most similar to L. senata (see also Lehmann et al., 2009). Female genitalia (Fig. 64): Antrum almost quadrate, posterior margin V-shaped; ductus bursae narrow, elongate; corpus bursa transversely oval, finely spiculose, provided with an anterior diverticulum.

Bionomies. Specimens are collected in January (Lehmann et al., 2009), February, March and April (Lehmann et al., 2009) and records are from altitudes 450– 950 m.

Additional data on distribution based on literature sources. Wiltshire (1942): Iraq (Table Mts.); Lehmann et al. (2009): Kuh-e Geno (Hormozgan prov.) and Shib Kuh (Bushehr prov.).
