( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Description. Female. Body medium-sized, form robust. Fastigium verticis protruding forward, depressed, about half as broad as scape, dorsal surface with a longitudinal furrow in the midline. Eyes elongate, moderate bulging ( Fig. 1H View FIGURE 1 ). Median ocellus very prominent, in size about as long as wide; lateral ocelli equally large occupying the sides of the fastigium verticis. Occiput with an indistinct median carina ( Fig. 1H, J View FIGURE 1 ). Apical segments of maxillary palpi longer than subapical ones, apices slightly swollen.
Disc of pronotum smooth, without longitudinal carina, anterior and posterior margins almost straight ( Fig. 1J View FIGURE 1 ); lateral lobes longer than deep, posterior margin slightly oblique without humeral sinus, ventral margins arc-shaped ( Fig. 1I View FIGURE 1 ). Mesonotum and metanotum with median carina.
Prosternum with 1 pair of spine-shaped processes, basal area of these processes separated, the apices subacute ( Fig. 1K View FIGURE 1 ); mesosternum with 1 pair of spine-shaped processes, the inner margins straight to base, the outer margins only straight as far as the middle ( Fig. 1K View FIGURE 1 ); metasternum with 1 pair of triangular processes, depressed, basal area of these processes jointed, the inner margins nearly straight, the outer margins arcuate with subapices slightly constricted forming 1 small nodular ( Fig. 1D View FIGURE 1 ).
Fore coxae swollen with 1 minute spine, middle coxae moderately swollen with 1 lamellate spine ( Fig. 1I View FIGURE 1 ); genicular lobes of fore and middle femora with apices obtuse, unarmed ventrally; genicular lobes of hind femora with 1 small inner spine or not, ventrally with 2–4 inner spines and 1 outer spine. Fore tibiae dorsally with 1 inner spine, ventral surface with 4 pairs of spines, apices with 1 pair of dorsal and ventral spines respectively, the dorsal spines longer than ventral ones; basal area of fore tibiae only with inner tympana, opened, oval, the outer tympana absent. Middle tibiae dorsally with 3 inner spines, 2 outer spines and 1 pair of apical spurs, the inner spines obviously longer than outer ones; ventral surface with 4 pairs of spines and 1 pair of apical spurs, the outer spines slightly longer than inner spines. Hind tibiae with 12–14 inner spines and 13–15 outer spines on dorsal surface, the inner spines longer than outer ones, and the large and small spines alternating arrangement, apices with 1 pair of long spurs; ventral surface with 1 inner spine and 2 outer spines, apices with 2 pairs of slightly more elongate spurs preceded by a pair of longer, subapical spines.
Posterior margin of tenth abdominal tergite arch-shaped concave, the lateral lobes rounded; epiproct linguiform. Cerci slender, crossed ( Fig. 1L View FIGURE 1 ), curved inner-dorsally. Subgenital plate nearly triangular, basal area broad, sharply narrowing, subapical area slightly constricted; apical area short, spine-shaped ( Fig. 1M View FIGURE 1 ). Ovipositor about half of hind femora, basal area stout, narrowing, apical half curved upward; dorsal valvulae obviously longer than ventral ones, apices of dorsal valvulae subacute ( Fig. 1L View FIGURE 1 ).
Male. Posterior margin of ninth abdominal tergite almost truncate, lateral margins with 1 pair of small semicircular lobes ( Fig. 1F View FIGURE 1 ); posterior margin of tenth abdominal tergite almost straight, lateral margins with 1 pair of sclerotized hooks which apices pointing forward, slightly inward and contiguous with the lobes of ninth abdominal tergite ( Fig. 1F View FIGURE 1 ). Paraproct with 1 pair of long processes, subcylindrical, curved dorsad, apices with 1 minute spine. Cerci conical, longer than the processes of paraproct, apices obtuse ( Fig. 1E View FIGURE 1 ). Subgenital plate longer than cerci, basal area broad, the basilateral margins curved dorsad, the lateral margins obviously narrowing to 1/3 basal area, the lateral margins of 2/3 apical area parallel; ventral surface with 1 pair of parallel longitudinal carina on lateral sides; posterior margin almost straight, slightly concave in the middle ( Fig. 1G View FIGURE 1 ). Styli developed, cylindrical, the length shorter than the distance between them ( Fig. 1G View FIGURE 1 ). Genitals membranous, with numerous minute denticles, without pronounced process ( Fig. 3–D View FIGURE 3 ).
Coloration. Body brown. Eyes yellowish, with 1 black spot below the median ocellus, basilateral area of labrum with 1 pair of black patterns ( Fig. 1A View FIGURE 1 ). The lateral margin of median carinae of occiput black. Disc of pronotum with yellowish brown stripe in the middle, the lateral area with 1 large black spot separately; anterior and posterior margins of pronotum, metathorax and abdominal tergites with irregular yellowish ridges ( Fig. 1C, J View FIGURE 1 ). Apical area of all femora and basal area of all tibiae with black rings, external surface of femora with irregular patterns. Posterior margin of ninth abdominal tergite with lateral lobes black apically.

Remarks. The new species differs from other known species of the genus in: median stipe of disc of pronotum yellowish brown, the lateral areas with 1 large black spot separately ( Fig. 1C, J View FIGURE 1 ); internal margin of middle femora with 1 minute spine; ventral surface of hind femora armed, dorsal surface with 12–14 inner and 13–15 outer spines; processes of metasternum angle-triangular, apices nodular ( Fig. 1D, K View FIGURE 1 ).
Etymology. Name is derived from the disc of pronotum with 1 pair of large spots.
