Preparations of genitalia: 2 3.

Description & Diagnosis. Wingspan 25–28 mm. White moths, forewing with a delicate, silvery grey shine while fresh, hindwings lighter; larger than L. ancyrana , forewing broader, much lighter and more whitish below, but also with a slight brownish tinge on forewing underside ( Fig. 24 View FIGURES 22 – 26 ). Male genitalia ( Fig. 50 View FIGURES 48 – 51 ) with the valve rather narrow, dorsal margin concave, sclerotized costa reaching one-half valve length, its apical projection thorn-like, diverging from valve margin, acutely pointed; harpe short, distally rounded, its dorsal arm strong, terminally straight and spined over a long distance, shorter than in L. farinata , griseata , ancyrana , luigi and palaestinensi s, a little longer than that of L. coassata . Farinata and coassata are similar in having a free apical process to the costa.

Bionomics. Specimens studied are collected in July only.

Distribution. Northern and central Tian-Shan in S Kazakhstan and NE Kyrgyzstan (Map 5).
