Description & Diagnosis. Wingspan 26–32 mm. Wings brownish-grey, with darker brown pattern elements. Similar to L. griseata griseata in size and wing-shape, but distinguishable by the presence of transverse bands or lines demarcating the median area of forewing and an oblique line reaching the apex of forewing. Also an indistinct antemedian line present. Underside concolorous, almost without pattern. Also similar to L. luigi, but the latter is smaller, the transverse lines are indistinct, less oblique and the submarginal line does not reach the apex (Fig. 22). Male genitalia (Fig. 48) similar to farinata, but the apical projection from costa shorter and pointed, curved ventrad; harpe rather elongate, dorsal arm shorter, stouter, with longer spines apically: Uncus longer, distally trucate, saccus shorter; aedeagus shorter, less narrow. Female genitalia (Fig. 71) with a narrow, tubular ductus bursae; corpus bursae globular, completely spined internally; a membranous anterior diverticulum is present.

Bionomics. Univoltine, common on irrigated and cultivated areas in arid zones. Specimens studied are collected end of March-beginning of June, at altitudes of 500–1100 m.

Additional data on distribution based on literature sources. Tsvetajev (1972): Repetek; Falkovitsh (1986): Uzbekistan; Mirzayans and Kalali (1970): Gonbad-e Qabus (Golestan prov.); Gorgan (Golestan prov.) (Lederer, 1871); Kopet-Dagh (Khorasan-e Shomali) (Viidalepp, 1988).

Distribution. Widely distributed from southern Ukraine and southern European Russia to SW Siberia, Turkmenistan and N Iran (Map 5).
