Supplementary description. Male. Posterior margin of tenth abdominal tergite with a pair of subparallel, elongate posterior processes. Cercus long, basal half cylindrical; inner margin near middle area with a rectangular, depressed lobe; subapical area compressed, apical area distinctly incurved, apex bluntly rounded. Subgenital plate with basal half slightly broad, basal margin with a triangular concavity; posterior margin shallowly concave. Styli conical and apices rounded, inserted on apices of lateral margins of subgenital plate.

Female. Cercus short and conical. Subgenital plate rectangular, longer than broad; lateral margins concave near base; center area of subgenital plate bulging; posterior margin shallowly concave. Ovipositor long and straight, basal area stout, dorsal valvulae with apices acute and ventral ones with apices hook-shaped.

Material examined. 1♂ 1♀, Jiuyishan, Ningyuan , Hunan, 7 August, 2019. coll. Tao Wang.

Measurements (mm). Body: ♂ 10.1, ♀ 11.8; pronotum: ♂ 3.4, ♀ 3.5; tegmen: ♂ 16.6, ♀ 17.05; hind femur: ♂ 9.1, ♀ 9.2; ovipositor: 10.4.

Discussion. Liu & Zhang (2000) described female subgenital plate with posterior margin truncate and without lateral carinae. Our team collected several specimens of this species in 2019, but the female differs markedly from the original description in: subgenital plate rectangular, longer than broad; the center area of subgenital plate bulging; posterior margin faintly concave. The original description of female may be error.
