Description (Figs. 12, 13). Wingspan 24 mm. Frons protruding about one-half of the eye diameter, spotted white and grey. Palpi rather long and narrow, reaching well beyond frons. Antennae filiform, finely and homogeneously pubescent in both sexes. Fore-tibia short and stout, 0.7 mm long, bidentate distally, with inner tooth-like projection as long as tibia. The last abdominal tergite of male terminally rounded, without a distinct buckle. Forewing ash-grey with postmedian line white, shaded dark grey proximally, projecting distad at veins M1, M3 and anterior to An, concave in between. Antemedian line rather indistinct, moderately angled in cell. Basal line posteriorly obsolete, but sharply angled in cell. Termen with a narrow, black line, interrupted at veins. Hindwing uniformly grey. Underside of forewings of a darker grey ground colour, with only the postmedial line faintly visible. Underside of hindwings lighter than upperside, with a darker marginal band. Male genitalia (Fig. 42). Uncus short, rather broad and triangular, distally hooked and finely pointed. Valve parallel-sided, distally rounded and finely dentate. Harpe long, running close to costa, its distal projection long as well, recurved and approaching the tip of the costal arm, the latter long and flattened at distal half. Sacculus broad at base, distally narrow, with a flat, elongate-triangular, distally rounded projection apically on right valva. This projection on left valva not flat, spine-like. Saccus long, distally rounded. Aedeagus long, curved in lateral view, with vesica covered with small, stout teeth. Female genitalia (Fig. 65). Antrum large, elongate, V-shaped, with internally oblique posterior margins and a deep central incision. Ductus bursae tubular, sclerotised, with a membranous stripe along its right side, extended into a broad, sclerotized field covering partly the membranous, proximal area of the corpus bursae. The latter slightly oval, densely spiculate at distal three fourths, with a small membranous anterior diverticulum.
Diagnosis. Resembling L. amoenata, but ground colour more uniformly grey, the medial area seems to be much broader due to the weakly marked antemedial line; hindwing grey, without a pale transverse band which is present in L. amoenata. Differs also considerably in the build of male and female genitalia, especially in the shape of aedeagus and valves. Also similar to the next species, but L. samandooki has the postmedial lines more strongly angled and distinctly double. The female genitalia (males are unknown) are similar, but the sclerotized antrum has a different shape. This is also true for L. dissocyma. In addition, this species has the postmedial lines situated much closer to the termen.
Distribution. Pakistanian part of Kashmir. Known from type locality only (Map 3).
Etymology. The name of the species is dedicated to the late Hungarian lepidopterologist and noctuid specialist, Martόn Hreblay, one of the collectors of the type material.
