Material examined. 1 male, Guangxi, Jinxiu, Changtongxiang, Daercun , 1,038m, 2015.VI.3, leg. J.-T. Zhao ( CCCC) ; 1 male, Guangxi, Jinxiu, Changtongxiang, Pingbancun , 1,338m, 2015.VII.17, leg. J.-T. Zhao ( CCCC) ; 1 male, ditto except 2015.VII.22, leg. J.-T. Zhao ( CCCC) ; 1 female, Hunan, Hupingshan, Xiangbizigou , 2005.VII.20, leg. Zhao & Li ( CBWX) .

Description. External characters refer to Lin (2017).

Male endophallus in everted condition ( Fig. 12 ) long and slender, about 3.8 times as long as median lobe; relative lengths of APH: MPH: BPH: PB: CT: MT = 1.0: 3.6: 0.8: 0.4: 1.5: 1.8.

MPH curved dorsally near middle, thence weakly curved ventrally toward apex; subdivided into MT, CT and PB by constrictions; MT evenly cylindrical; CT elongate, strongly swollen latero-ventrally at base with small spicules, then gradually expanded before basal third; PB with anterior bulb moderately developed. APH with apical bulb (ab) ca. 0.5 times as long as apical bubble (bb); apical bulb weakly sclerotized, short inverted trapezoid, surface with surface with microspinules irregular, not forming transverse rows, which becoming denser apically; bb strongly prominent at base forming a ventral bulge, provided with a pair of apical rod-like sclerite which is about half of its length.

Distribution. China: Henan, Hunan, Shaanxi, Guangxi (new Province record).

Remarks. As the southernmost distribution of this species, the population from Guangxi with relatively more reduced pronotal and elytral (basal) maculae, which represents an extreme form of intraspecific variation. The endophallic structure of this species is unique among all studied species of the genus in having a rather elongate CT, and bb of APH provided with a distinct ventral bulge at base.
