Figs 1C, 6A, 10C, 15C
Diagnosis
The new species is similar to L. montiatilis Park, 2009 in appearance by sharing a narrowly elongate forewing with an extremely oblique termen. It can be distinguished from L. montiatilis by having the hindwing with M 3 and CuA 1 coincident, and in the male genitalia by the cucullus gradually narrowed to apex; whereas in L. montiatilis, the veins M 3 and CuA 1 are stalked in the hindwing, and the cucullus is broad in basal ⅓ and extremely narrow in distal ⅓ (Park 2009: 62, fig. 10).
Etymology
The specific epithet is derived from the Latin “ angustifolius ”, referring to the narrowly elongate forewing.

ADULT (Figs 1C, 6A). Wingspan 11.5‒12.0 mm. Head greyish brown, with pale orange scales laterally. Antenna pale orange; dorsally flagellum ringed with dark brown. Labial palpus pale orange; second palpomere mixed with dark brown scales on outer surface; third palpomere slightly shorter than second palpomere. Thorax and tegula greyish brown. Forewing narrowly elongate, costal margin slightly arched, apex blunt, termen extremely oblique; ground colour greyish brown, mixed with blackish brown scales; markings blackish brown: basal streak wide at base; discal stigma small; discocellular stigma larger, elliptical; fringe greyish brown; R 3, R 4 and R 5 stalked, R 5 to termen near apex, M 2 and M 3 subparallel, CuA 1 and CuA 2 short-stalked. Hindwing and fringe grey; fringe with orange white basal line; M 3 and CuA 1 coincident.
MALE GENITALIA (Fig. 10C). Uncus inverted subtrapezoidal, concave in broad V-shape on posterior margin; caudal lobe short digitiform, setose, rounded apically. Gnathos with basal plate trapezoidal; median process wide at base, narrowed to distal ⅓ where it is curved, then slender to pointed apex. Valva broad basally, narrowed to cucullus; ventral margin arched; cucullus about half as long as valva, slightly narrowed to rounded apex, shallowly concave on costal margin, setose, with several bullet-shaped setae basally along ventral margin; costal bar narrow, gently angled at middle; sacculus wide at base, narrowed to middle, then uniform to cucullus. Vinculum broad; saccus not developed, blunt on anterior margin. Juxta shield-shaped, semicircularly concave on posterior margin, produced at middle on anterior margin; posterior lobe semiovate basally, slender distally, extending outward. Aedeagus about 5/6 length of valva, tubular and arched, with two dorsal denticles of different sizes, with dense granules in vesica; cornuti consisting of row of spines at basal ⅓ and large sclerite bearing 2 denticles.
SEVENTH ABDOMINAL STERNITE (Fig. 15C). Anterolateral rib thin, forked basally, reaching before posterior margin of sixth abdominal sternite; posterolateral lobe weakly sclerotized, triangular.
