Additional description notes, both sexes. Fore coxae with 1 spine. Fore and middle femora unarmed, hind femora with 7–10 internal and 5–6 external spines on ventral surface. Fore and middle tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces; hind tibiae dorsally with 7–8 spines and 1 apical spur on each side, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs. In female from Mao´ershan, Guangxi, hind femora with 8–11 internal and 7–8 external spines on ventral surface, tibiae with 6 internal and 6–7 external spines on dorsal surface. Hind femora of male from Guadun, Fujian with 8–9 internal and 7–8 external spines on ventral surface, tibiae dorsally with 5–6 internal and 6 external spines.

Male from Mao´ershan, Guangxi. Tegmina (damaged, Fig. 7 ): RS arises from radius; media anterior free from base; cubitus anterior of left tegmen at base single branched, after divides before basal quarter into two branches, the anterior branch makes a curvature and receives a short connection branch from MA, shortly after it divides into MP and CuA1, while MP of right tegmen absent; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem.

Male (XZ183). Tegmina ( Fig. 10C–D ): RS+M arises from radius at base, radius forked subapical area, MP separated from RS+M as the first branch and after fused with CuA 1 in short distance and then again divided; MA arises from RS+MA and then fused with MP and remains single branch till tip ( Fig. 10C ), but in right tegmen MA and MP fused at tip ( Fig. 10D ); CuA2 single branch; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem.

Female (20A94). Tegmina ( Fig. 14C–D ): Radius releases RS between apical third and apical fourth area of tegmen, both forked again near tip; media anterior free from base, but right tegmen divides into two branches about apical quarter; cubitus anterior divides into two branches about basal quarter, the first branch connected with MA, then immediately divided and runs as MP+CuA1 till tip, the posterior branch (CuA2) does not divide further too; cubitus posterior undivided, free throughout; with 3 anal veins.

Measurements (mm). Male: BL 28.0, PL 5.0, TL 19.0, HFL 16.0; Female (20A94): BL 36.4, PL 7.1, TL 25.8, HFL 17.6, OvL 25.1; Male (XZ183): BL 24.9, PL 6.5, TL 26.2, HFL 15.4.

Material examined. 1 male, Mao´ershan , Guangxi, October 5, 2021, 25.894458° N, 110.478096° E, alt. 1333 m, coll. by Xiangyi Lu ; 1 female (20A94), Mao´ershan , Guangxi, August 17, 2020, coll. by Wei Bin ; 1 male (XZ183), Guadun, Wuyishan , Fujian, May 25, 2021, coll. by Lang Wang .

Distribution. Fujian (Fuzhou, Guadun), Hubei (Tongshan), Hunan (Hengshan), Jiangsu, Zhejiang (Lin´an, Longquan).

Discussion. The specimens from Mao´ershan, Guangxi, darker than the specimen from Fujian.
