Type material. CHINA, Guangxi: Holotype ♂, Shaoping Forest Farm, Pingxiang , 190 m, 26.VII.2012, leg. BB Hu et al., slide No. TZL19689 . Paratypes: 2♂, Shaoping Forest Farm, Pingxiang , 280 m, 15–19.IV.2012, leg. XF Yang, slide No. TZL19693 ; 1♂, Shaoping Forest Farm, Fingxiang , 280 m, 14.IV.2013, leg. XF Yang, Slide No. TZL19694 .

Diagnosis. The new species can be distinguished from its congeners by the costal part of the valva with an apical spine directed ventrad, the saccular part of the valva with a spine beyond basal 2/3 on the dorsal margin, the vase-shaped juxta and the aedeagus with a cluster of fine spines distally.

Description. Adult ( Fig. 4 ). Wingspan 17.0– 17.5 mm. Head shining fuscous, with purplish shine laterally. Antenna with scape blackish brown, with a longitudinal streak along midline dorsally, with yellow scales on ventral surface; flagellum yellow, ringed with brown on dorsal surface. Labial palpus with second palpomere blackish brown, tinged with yellow on inner surface; third palpomere black basally, yellow mixed with black scales distally. Thorax yellowish brown; tegula pale purple basally, pale yellow distally. Forewing yellow, mixed with brown scales, denser between fold and dorsum basally as well as between subterminal fascia and terminal margin; costal margin black basally, forming a large basal patch; discal, discocellular and plical spots blackish brown, discal spot smallest, discocellular spot transversely narrow, sub-rectangular; tornal spot represent by scattered blackish brown scales; subterminal fascia yellowish brown, from distal 1/4 of costal margin sinuate to tornus; terminal dots blackish brown, extending from preapex along termen to tornus; fringe brownish yellow basally, yellow distally. Hindwing and fringe yellowish brown. Fore- and midlegs dark brown on dorsal surface, yellow on ventral surface; hindleg with femur whitish yellow on ventral surface, blackish brown on dorsal surface, tibia yellow on dorsal surface, blackish brown on ventral surface, tarsus dark brown on outer surface except yellow at apex of each tarsomere, yellow mixed with brown on inner surface; spurs yellow on dorsal surface, dark brown on ventral surface.

Male genitalia ( Fig. 9 ): Tegumen arched, lateral part broad. Gnathos widely banded, slightly produced posteromedially. Costal part of valva wide at base, gradually narrowed to apex, curved before apex; apex rounded, with a spine-shaped process directed ventrad almost at a right angle; costal margin with a narrow sclerotized flap basally; saccular part of valva with basal half uniformly narrow, widened from middle to beyond basal 2/3, thereafter triangularly narrowed to pointed apex; dorsal margin with a spine beyond basal 2/3, finely serrate from this spine to apex; ventral margin smooth. Juxta weakly sclerotized, vase-like; anterior margin sclerotized, with a notch in middle; median portion broadened, roundly arched outward laterally; distal 2/5 digitate. Aedeagus straight, slightly shorter than saccular part of valva, with a cluster of fine spines distally ( Fig. 9a ); cornuti consisting of a bundle of easily shed long spines.

Female unknown.

Distribution: China (Guangxi).

Etymology. The specific epithet is derived from the type locality of the species (Pingxiang).
