Description & Diagnosis. Wingspan 19.5– 24 mm. Forewing brownish grey with indistinct brownish bands and lines from costa to hind margin, parallel to the distal margin of wing. Only the postmedial line is relatively distinct, brownish, accentuated darker at veins (Fig. 19). Male genitalia (Fig. 46) characterized by the extremely broad and stout uncus and the valve costa ending in a short, pointed projection. Harpe reduced to a dentate, sclerotised band in the middle of the valve, the long dorsal projection spinose in distal half, reaching more than one-half the length of valve; juxta deeply V-shaped grooved. Saccus short, rounded. Aedeagus slightly curved, coecum inflated. Female genitalia (Fig. 69) with apophyses posteriores about three times longer than ap. anteriores; sclerotised antrum absent, ductus bursae and corpus bursae membranous, with membranous anterior diverticulum (Fig. 69). A species similar in shape and coloration is L. luminosata, which is a little larger, and lighter, especially in the hindwings, and lacks the darker transverse lines on the forewing upperside. It differs also in the finger-shaped uncus, the larger, triangular saccus, and the much stronger ornamentation of the valve.
Bionomics. Moths possibly bivoltine, occurring in March-April and July. Probably associated with Malcolmia turkestanica (Cruciferae), growing on sands in the desert (Shchetkin, 1965b).
Additional data on distribution based on literature sources. Shchetkin (1965b): Tajikistan, Uzbekistan, Turkmenistan. Falkovitsh (1986): Uzbekistan.
Distribution. SE Turkmenistan, S Uzbekistan and SW Tajikistan (Map 4).
