Hind femora beneath with 6 inter spines and without outer spines; hind tibia above with 31–41 outer spines and 31–34 inter spines, inner subapical spur of hind tibia about equal to length of hind metatarsus. Hind metatarsus with 2 dorsal spines. Apex of paraproct with a small projection ( Fig. 19 ). Process of 7th abdominal tergite with a globular swell ( Figs. 19–20 ). Male genitalia with blunt apex of dorso-median lobe and widening to basal part ( Fig. 21 ).

Female. Subgenital plate nearly triangular, both sides of basal part strongly prominent and apex with a deep notch ( Fig. 22 ). Ovipositor longer than the half of hind femora.

Coloration. Body dark brown. Face with 4 black longitudinal bands. Legs with dark stripes and knee lobes with distinct marks.

Measurements. (length in mm) Body Ƌ16.0–21.0, ♀15.0–20.0; pronotum Ƌ4.0–6.0, ♀5.0–6.0; fore femora Ƌ15.0–16.0, ♀13.0–16.0; hind femora Ƌ28.0–30.0, ♀29.0–31.0; hind tibia Ƌ30.0–33.0, ♀31.0–34.0; ovipositor 17.0–19.0.

Material examined. Holotype, 1♂, Daming Mountain, alt. 1250m, 2013. VII.19–25, collected by Liu Xian- Wei et al.; paratype, 6ƋƋ, 15♀♀, same data as holotype; 1Ƌ, Jiuwan Mountain, Guangxi, alt. 1200m, 2015. VII.19, collected by Liu Xian-wei et al ..

Distribution. China (Guangxi).
