Diagnosis. The new species belongs to the M. scripta - M. yakovlevi species-group and shows closer relationship to M. yakovlevi by the features of the genitalia. M. nanlinga differs externally from M. yakovlevi by its somewhat broader forewing, finer, but continuous ante- and postmedial lines—those are stronger, but interrupted in M. yakovlevi —and the much darker, sharply defined, double, very dentate medial line, which is much paler and diffuse in the related species. In the male genitalia, the new species is different from M. yakovlevi by the somewhat shorter and broader, more evenly tapering uncus; the broader caudal and smaller basal lobes of valva; the much thicker, straight harpe and the conspicuously longer vinculum; the vesica of the new species is somewhat shorter than that of M. yakovlevi , bearing slightly shorter cornutus. In the female genitalia, the new species has, in comparison with the related taxa, shorter and thicker apophyses anteriores and shorter and broader ductus bursae. The signum bursae is completely different in the two closely related species: M. nanlinga has a broad, transverse stripe-like signum, that of M. yakovlevi is an elongated, arrow-like structure.

Description. Adult ( Figs. 5, 7 ). Wingspan 21–24 mm. Head grayish white; antenna brown, bipectinate in male, filiform in female; labial palpus short, with brown scales. Thorax brown. Collar grayish yellow with black. Abdomen brown. Forewing ground color pale brownish gray; basal line poorly discernible; antemedial line black, double, inner line poorly visible, strongly curved in its upper third; medial line blackish, sharply defined, running close to postmedial line, conspicuously strongly zigzagged; postmedial line blackish, rather sharply defined, with upper half arcuate, lower half straight; subterminal line dark grayish, interrupted; cilia grayish brown. Hindwing more or less unicolorously brownish gray; cilia grayish brown. Male genitalia ( Fig. 6 ): Uncus relatively short, gradually tapering, apically pointed; tegumen thin, medium long; valva bifurcate, dorsal lobe elongated, slightly constricted medially, proximo-ventral lobe small, triangular; cucullus smooth; costal margin sclerotized, humped at basal part; sacculus simple, broad; harpe robust, broadened medially, with serrate-dentated dorsal surface and rounded at apex; vinculum narrow and long, as long as tegumen. Aedeagus medium long and cylindrical; vesica with medium-sized, acute cornutus. Female genitalia ( Fig. 8 ): Papillae anales broad and short; apophyses posteriores moderate; apophyses anteriores very short, rather broad, apically truncated; ostium bursae slightly sclerotized, V-shaped; ductus bursae rather long, sclerotized, flat and twisted, longer than corpus bursae; corpus bursae membranous with two narrow transverse signum bands, cranial band much longer than caudal one.

Distribution. China (Guangdong, Guangxi, Jiangxi, Taiwan).

Etymology. The specific name is derived from the type-locality, Nanling.
