It can be distinguished by having the forewing with R 3 and R 4+5 arising from the same point, and in the male genitalia by the cucullus widened medially; whereas in L. meyricki , the forewing has veins R 3 and R 4+5 stalked and the cucullus is narrowed from base to apex ( Gozmány 1978 : pl. 25 fig. 37). Etymology The specific epithet is derived from the Latin “ astictus ”, referring to the forewing without maculation. Type material Holotype CHINA – Yunnan Province • ♂ ; Tengchong City , Xiaodifang ; 24º52′ N , 98º45′ E ; 2116 m a.s.l. ; 12 Jul. 2014 ; K.J. Teng et al . leg.; slide no. YS19603 ; NKU .

Antenna pale orange; flagellum ringed with dark brown. Labial palpus pale yellow; third palpomere shorter than second palpomere. Thorax and tegula yellowish brown. Forewing widened distally, costal margin slightly arched, apex rounded, termen oblique; ground colour greyish brown; basal streak dark brown, distinct at base; fringe greyish brown, with pale yellow basal line; R 3 and R 4+5 arising from same point, R 4 and R 5 long-stalked, R 5 to apex, M 2 and M 3 subparallel, CuA 1 and CuA 2 short-stalked. Hindwing and fringe greyish brown; M 3 and CuA 1 long-stalked. MALE GENITALIA ( Fig. 10D ). Uncus subtriangular, shallowly concave on posterior margin; caudal lobe short digitiform. Gnathos with basal plate subquadrate, roundly produced on posterior margin; median process broad in basal ⅓, narrowed to distal ⅓, distal ⅓ slender to pointed apex, curved ventrad at distal ¼. Valva broad and parallel-sided basally, narrowed to cucullus; cucullus about half as long as valva, slightly widened medially, narrowed from middle to narrowly rounded apex, nearly straight on costal margin, setose ventrally, with several bullet-shaped setae ventrobasally; costal bar narrow in basal half, widened from middle toward valva, gently angled at middle; sacculus distinct basally, taenioid. Vinculum broad; saccus not developed, rounded on anterior margin. Juxta shield-shaped, with small notch at middle on posterior margin, produced at middle on anterior margin; posterior lobe semiovate basally, narrow taenioid distally, extending outward. Aedeagus shorter than valva, arched, wide at base, narrowed to basal ⅓, thereafter tubular, without dorsal denticle, with dense granules in vesica; cornuti consisting of elliptical ring placed medially, cluster of spinules from basal ¼ to before middle, and several spines at distal ¼. SEVENTH ABDOMINAL STERNITE ( Fig. 15D ). Anterolateral rib thin, forked basally, curved distally, reaching posterior margin of sixth abdominal sternite; posterolateral lobe weakly sclerotized, triangular. Female Unknown.
