Diagnosis
The new species is similar to L. neosticta Meyrick, 1918 in the male genitalia. It can be distinguished by the hindwing with M 3 and CuA 1 coincident, and the male genitalia with the cucullus about 3/5 the length of the valva and widened distally; whereas in L. neosticta, the hindwing has M 3 and CuA 1 stalked, the cucullus is half the length of the valva and narrowed distally.
Etymology
The specific epithet is derived from the Latin “ flav -” and “ striatus ”, referring to the forewing with an orange-yellow stripe along the costal margin distally.

Description
ADULT (Figs 2E, 7B). Wingspan 12.0‒ 12.5 mm. Head brown, with orange yellow scales laterally.Antenna pale orange; flagellum ringed with dark brown. Labial palpus pale orange except dark brown ventrally on third palpomere; third palpomere shorter than second palpomere. Thorax and tegula brown. Forewing with costal margin slightly arched, apex rounded, termen oblique; ground colour dark brown, orange yellow along costal margin from distal ¼ to before apex forming short stripe; discal and discocellular stigmata blackish brown, ill-defined; tornal streak blackish brown; fringe greyish brown; R 3 close to R 4+5 at base, R 4 and R 5 stalked for half length of R 5, R 5 to costal margin before apex, M 2 and M 3 separated, CuA 1 and CuA 2 short-stalked. Hindwing and fringe greyish brown; fringe with orange white basal line; M 2 and M 3 +CuA 1 arising from same point, M 3 and CuA 1 coincident.
MALE GENITALIA (Fig. 11E). Uncus Y-shaped; caudal lobe digitiform, rounded and setose apically. Gnathos with basal plate rounded on posterior margin; median process narrowly elongate, wide at base, narrowed to distal ⅓ where it is curved, then slender to a pointed apex. Valva broad basally, narrowed before cucullus; cucullus about 3/5 length of valva, narrowed slightly before middle, then widened to obliquely blunt apex, shallowly concave on costal margin, setose on ventral half; costal bar narrow in basal half, widened from middle toward valva, gently angled at middle; sacculus distinct basally, narrow taenioid. Vinculum broad; saccus semiovate. Juxta shield-shaped, concave at middle on posterior margin, with triangular process at middle on anterior margin; posterior lobe narrow taenioid, extending outward. Aedeagus about ¾ length of valva, uniform except slightly wider at base, gently curved, without dorsal denticle, with dense granules in vesica; cornuti consisting of anchor-shaped sclerite apically, basally curved bar about ⅓ length of aedeagus, recurved sclerite placed medially and band of spines at distal ⅓.
SEVENTH ABDOMINAL STERNITE (Fig. 16B). Anterolateral rib thin, forked basally, extending obliquely outward distally, not reaching posterior margin of sixth abdominal sternite; posterolateral lobe weakly sclerotized, subtriangular.
FEMALE GENITALIA (Fig. 19A). Eighth abdominal sternite slightly concave at middle on posterior margin. Apophyses posteriores about twice as long as apophyses anteriores. Antrum cup-shaped, slightly longer than wide, spiculose. Ductus bursae nearly as long as corpus bursae, narrow, dilated medially; ductus seminalis dilated subbasally and forming elliptical sac, then slender, arising from about posterior 2/5 of ductus bursae. Corpus bursae ovate, granulose; signum subrounded, denticulate, situated posterior to middle of corpus bursae.
Distribution
China (Yunnan).
