Diagnosis. The new species is similar to L. empolaea Meyrick, 1914 in the male genitalia. It can be distinguished by the costal part of the valva with basal 2/3 uniformly wide and distal 1/3 narrowed to apex, and the saccular part of the valva with ventral margin sinuate in basal half and concave inward in middle; in L. empolaea, the costal part of the valva is gradually narrowed from base to apex, and the saccular part of the valva is obliquely straight in basal 2/3 on the ventral margin (Clarke 1963: pl. 151, fig. 2).
Description. Adult (Fig. 5). Wingspan 14.0–18.0 mm. Head brown, with purplish sheen. Antenna with scape dark brown; flagellum yellow, ringed with brown on dorsal surface. Labial palpus with second palpomere yellowish brown on inner surface, brown on outer surface; third palpomere brown except yellow at apex. Thorax and tegula greyish brown basally, light yellowish distally. Forewing yellow; costal margin blackish brown on basal 2/9, forming an ill-defined large basal patch, with a diffused blackish brown spot beyond distal 1/3; discal, discocellular and plical spots blackish brown, discocellular spot transversely sub-rectangular, largest, divided into two small dots by mesial interruption, plical spot rounded, smallest; tornal spot blackish brown, rounded, diffused; subterminal fascia yellowish brown, from beyond distal 1/3 of costal margin extending inward to tornus; terminal dots blackish brown, running from preapex along termen to tornus; fringe yellow. Hindwing and fringe greyish brown. Fore- and midlegs dark brown on dorsal surface, yellow mixed with grey on ventral surface; hindleg yellow, in some individuals mixed with brown scales on outer surface, black at each tarsomere basally; inner spurs yellow mixed with brown, outer spurs brown.
Male genitalia (Fig. 10): Tegumen arched, widened medially, obtusely rounded on posterior margin, lateral part narrow. Gnathos transversely banded, dumbbell-like, uniformly narrow and straight medially, ovately dilated laterally. Costal part of valva with basal 2/3 uniformly wide, distal 1/3 narrowed to pointed apex, densely setose; saccular part of valva wide at base, distinctly narrowed to before middle, shrunk medially, elliptically dilated and setose distally, rounded apically; dorsal margin straight; ventral margin sinuate in basal half, concave inward medially. Juxta rectangular; anterior margin narrowly sclerotized, obtuse, with a notch in middle; lateral margin heavily sclerotized, straight, dilated distally, club-like as a whole. Aedeagus straight, longer than saccular part of valva, with dense denticles and granules; cornuti consisting of two shorter stout spines and a large bundle of slender, easily shed spines running from basal 1/4 to distal 1/4 (Fig. 10a).
Female unknown.
Distribution. China (Guangxi, Guizhou, Hunan).
Etymology. The specific epithet is derived from the Latin similis meaning similar, and the specific name of its closely allied species empolaea.
