Hind femora beneath with 7–8 inter spines and without outer spines; hind tibia above with 32–33 outer spines and 31–32 inter spines, inner subapical spur of hind tibia about equal to length of hind metatarsus. Hind metatarsus with 2 dorsal spines. Apex of process of male 7th abdominal tergite quite straight ( Fig. 23 ). Paraproct of male with a projected angular apex ( Fig. 24 ). Male genitalia with 2 small apical tubercles of dorso-median lobe and hardly widening to basal part ( Fig. 25 ).

Female. Subgenital plate nearly trapezoid and apex with a broad notch ( Fig. 26 ). Ovipositor longer than the half of hind femora.

Measurements. (length in mm) Body Ƌ13.5–18.0, ♀12.0–14.0; pronotum Ƌ4.5–5.5, ♀4.5–6.5; fore femora Ƌ9.5–12.5, ♀11.0–15.0; hind femora Ƌ21.5–24.0, ♀19.5–27.0; hind tibia Ƌ23.0–25.0, ♀20.0–30.0; ovipositor 15.0–20.0.

Material examined. Holotype, 1♂, Maoer Mountain, Guangxi, alt. 500–2100m, 2013. VII.19–VIII.6, collected by Liu Xian-Wei et al.; paratype, 11ƋƋ, 8♀♀, same data as holotype; 1Ƌ, Maoer Mountain, Guangxi, alt. 800–1100m, 2012. VII.23–24, collected by Bi Wen-Xuan et al ..
