Diagnosis
The new species is similar to L. manesa Wu & Liu, 1992 in the male genitalia. It can be distinguished by the forewing bearing a tornal streak, by the aedeagus without a dorsal denticle in the male genitalia, and in the female genitalia by the signum of the corpus bursae being without denticles. In L. manesa , the tornal streak is absent, the aedeagus has two dorsal denticles, and the signum has dense denticles ( Wu & Liu 1992: 679, fig. 2140).
Etymology
The specific epithet is derived from the type locality Yunnan.

Description
ADULT ( Figs 5D View Fig , 9D View Fig ). Wingspan 12.0‒13.0 mm. Head yellowish brown. Antenna pale orange; flagellum ringed with dark brown. Labial palpus pale orange on inner surface, dark brown on outer surface; second palpomere roughly scaled dorsally; third palpomere nearly as long as second palpomere. Thorax and tegula brownish yellow. Forewing with costal margin slightly arched, apex blunt, termen oblique; ground colour brown, mixed with dense rough yellowish brown and greyish brown scales in distal ⅓; basal streak dark brown, distinct at base; markings black: discal stigma small; discocellular stigma larger, elliptical; tornal streak wide, reaching before discocellular stigma anteriorly; fringe dark grey, basal line pale brownish yellow; R 3, R 4 and R 5 stalked, R 5 to termen, M 2 and M 3 free, CuA 1 and CuA 2 short-stalked. Hindwing and fringe grey; fringe with basal line pale yellow; M 3 and CuA 1 stalked for about half length of M 3.
MALE GENITALIA ( Fig. 14D View Fig ). Uncus subtriangular, shallowly concave on posterior margin. Gnathos with lateral arms broad, triangularly produced on posterior margin; median process wide at base, narrowed to distal ¼, thereafter slender to pointed apex, curved ventrad preapically. Valva broad basally; cucullus longer than half length of valva, slightly narrowed to before rounded apex, shallowly concave on costal margin, densely setose, with several bullet-shaped setae medially along ventral margin; costal bar narrow, gently arched; sacculus narrow, reaching cucullus. Vinculum broad; saccus not developed. Juxta shield-shaped, gently concave at middle on posterior margin; posterior lobe narrow, extending outward. Aedeagus about 4/5 length of valva, wide at base, narrowed to blunt apex, without dorsal denticle; cornuti consisting of two bundles of spines at basal ⅓ and ⅔ respectively, curved sclerite about ¼ length of aedeagus and bearing apical spine.
SEVENTH ABDOMINAL STERNITE ( Fig. 17K View Fig ). Anterior margin bell-shaped; anterolateral rib thin and curved, reaching before posterior margin of sixth abdominal sternite; posterolateral lobe elongate, triangular, and slender distally.
FEMALE GENITALIA ( Fig. 21C View Fig ). Eighth abdominal sternite arched gently on posterior margin. Apophyses posteriores about twice as long as apophyses anteriores. Antrum weakly sclerotized, cup-shaped, spiculose. Ductus bursae nearly as long as corpus bursae, widened toward corpus bursae, anterior part as wide as corpus bursae; ductus seminalis dilated subbasally and forming subrounded sac, then slender. Corpus bursae elliptical; signum at middle, elliptical, posteriorly with semiovate flap.
