Figs. 14–19

Additional description notes, both sexes. Tegmina surpassing the apex of abdomen, reaching basal third of hind tibiae. Tegmen ( Figs. 15C , 17A–B ): radius with RS branching about middle of tegmen, both forked near tip; media anterior free from base but leaning on radius; cubitus anterior single branched at base, after divides into two branches behind basal third of tegmen, the anterior branch makes a curvature and receives a short connection branch from MA, shortly after it divides into MP and CuA1, CuA2 single branched; cubitus posterior undivided, free throughout. Right tegmen of male specimens from Funing, Yunnan ( Fig. 15D ): radius with RS branching about apical third of tegmen, both forked near tip; media anterior free from base but leaning on radius, about basal quarter fused with R, shortly after MP arises from R, while MA arises from R behind middle of tegmen; cubitus anterior at base single branched, after divides behind basal third of tegmen into two branches, the anterior branch makes a curvature and connects with MP, then fused with CuA 2 in short distance, after divides again into two veins CuA1 and CuA2; cubitus posterior forks between basal third and middle area of tegmen into two branches, the first branch connects with CuA2 then separated, the second branch undivided, free throughout. Cubitus anterior of female left tegmen undivided, free throughout ( Fig. 19C ). MA arises from R behind middle area of female right tegmen, shortly after fused with MP, then remains single-branched till tip; CuA1 is fused with MP in basal third, then divides into two branches, MP and CuA1, the second branch shortly again forks into two veins; CuA2 separated from base; cubitus posterior undivided, free throughout. All tegmina: with 4 anal veins, the last two with common stem.

Material examined. 1 male and 1 female, Longbang, Jingxi, Guangxi, May 16, coll. by Fuquan Zhou ; 2 males, Naneng, Funing, Yunnan, May 5, 2021, coll. by Min Li .

Distribution. Guangxi (Jingxi, Longsheng), Guizhou (Yanhe), Hubei (Wufeng), Yunnan (Funing).

Discussion. The shape of spines of male ninth abdominal tergite is very similar to the Furcilarnaca pulex (Karny, 1928) .
