Color.
Head, mesonotum and legs stramineous; pronotum and tegmina white brown; eyes brown; tegmina with many small round black spots (
Fig. 5
).
Morphology.
Body length:
16 mm
.
Head: Vertex 4.4 times as wide as long (
Fig. 5
A); frons slightly longer than wide (
Fig. 5
B); frontoclypeal suture shallowly convex (
Fig. 5
B); rostrum extending to meso-trochanter.
Thorax: Pronotum anterior margin convex; lateral margin extending lateral-ventrally; postocular eminence ridged (
Figs. 5
C, 6C). Mesonotum posterior angle about 90° (
Figs. 5
A, 6A). Metatibia with seven spines apically; basal segment of metatarsi with nine spines apically. Tegmina with costal margin slightly convex at base; apical margin elongate convex; sutural margin truncate; apical angle convex; sutural angle slightly rounded, about 90°; vein Cu once forked, the branches joining postclaval margin (
Fig. 5
D).
Male genitalia: Pygofer quadrangular; dorsal margin strongly concave (
Fig. 6
D). Genital style slightly hemispherical with a short process at dorsal apex (
Fig. 6
D). Anal tube large and long in lateral view, widest subapically, bent down at midlength (
Fig. 6
D). Phallobase tubular at base in lateral view; dorsolateral lobe slender, apex each side with two processes, all very small (
Figs. 6
E, H); lateral emargination deeply concave; ventral lobe long, with many spine-like processes (
Fig. 6
E). Theca bearing one small forked process at middle on each lateral side (
Fig. 6
F); apex bipartite, concave deeply (
Fig. 6
G), each side with two processes, anterior one slightly shorter than phallus and heavily branched, posterior one simple and circled (
Figs. 6
F, G).

Etymology.
The specific name is derived from the name of the
holotype
locality, Pingjiang.
Distribution.
China
(Guangxi).
Remarks.
This new species differs from other similar species of the genus by the dorsolateral lobe of phallobase bearing two pairs of short processes at apex (
Figs. 6
E, H) and the male theca bearing a small process near middle of flank (
Fig. 6
F).
