Description. Male. Body large. Fastigium verticis projecting forward, about three-fourths as wide as scape, dorsal surface with longitudinal carina along the midline ( Fig. 1A View FIGURE 1 ). Ocelli distinct, median ocellus oval, slightly longer than wide; lateral ocelli oval, suited on the lateral margins of fastigium verticis. Eyes projecting outwards. Apical segment of maxillary palpi longer than subapical ones, apices slightly swollen ( Fig. 1B View FIGURE 1 ).

Disc of pronotum smooth, without longitudinal carina, anterior margin slightly concave in the middle, posterior margin almost straight; lateral lobes longer than deep without humeral sinus, ventral margins arc-shaped ( Fig. 1A View FIGURE 1 ).

Prosternal lobes spine-shaped, basal area separated, apices subacute; mesosteral lobes acutely angular, the basal area slightly swollen and separated, afterwards elongate, conical to nearly cylindrical with obtuse tip; metasternal lobes obtusely angular, basal area separated from each other, internal margin almost straight, external margin slightly convex ( Fig. 1C View FIGURE 1 ).

Fore coxae swollen, with 1 strong spine; middle coxae with 1 depressed spinule ( Fig. 1B View FIGURE 1 ); fore and middle femora ventrally unarmed; hind femora with 7 – 15 internal spines on ventral surface; apices of genicular lobes of fore and middle femora with 1 internal spinule, external surface with obliquely stripes. Dorsal surface of fore tibiae with 2 internal spines, ventral surface with 4 pairs of spines; apices with 1 pair of spines on dorsal and ventral surfaces separately, and the internal spines obviously longer than external ones; basal area of tibiae with oval, opened tympana on both sides, the internal one slightly larger than external one ( Fig. 1J–K View FIGURE 1 ). Middle tibiae with 4 internal and 3 external apical spines on dorsal surface, ventral surface with 5 pairs of apical spines. Hind tibiae dorsally with 11 – 10 internal and 9 – 11 external spines, the internal ones as long as external ones, apices with 1 pair of spines, the external spine longer than internal one; ventral surface with 4 internal and 2 external spines, apices with 1 subapical spine, 1 long apical spine and 1 short spine on each side.

Wings small, laterad and justly reaching the posterior margin of metanotum or anterior margin of first abdominal tergite ( Figs. 1B View FIGURE 1 , 4A View FIGURE 4 ). Hind wings covered by tegmina.

Posterior margin of ninth abdominal tergite arched concave, lateral margin with 1 dactylitic process on each side ( Fig. 1F View FIGURE 1 ); posterior margin of tenth abdominal tergite almost straight, lateral areas with a pair of up-curved hooks inserted just laterally of the processes of ninth abdominal tergite ( Fig. 1D, F View FIGURE 1 ). Paraprocts triangular with a pair of long and upcurved processes, sickle shaped in lateral view ( Fig. 1D–E View FIGURE 1 ). Cerci conical, about as long as paraprocts, apices obtuse ( Fig. 1D View FIGURE 1 ). Subgenital plate longer than cerci, basal area broad, narrowing to apex, ventral surface with 1 pair of parallel longitudinal carinae; posterior margin slightly concave ( Fig. 1G View FIGURE 1 ). Styli cylindrical, as long as the wide between them.

Female. Body large. Wings reaching the posterior margin of metanotum. Cerci conical, apices acute. Subgenital plate longer than wide, basal area triangular, about 1.2 times as long as apical spine ( Figs. 2E View FIGURE 2 , 3G View FIGURE 3 ). Ovipositor curved dorsad, basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices of dorsal valvulae obtuse, apices of ventral valvulae acute ( Figs. 2F View FIGURE 2 , 3F View FIGURE 3 ).

Coloration. Body brown with yellowish spots ( Fig. 3A–B View FIGURE 3 ). Face yellowish brown with black spots ( Figs. 3C View FIGURE 3 , 4C–D View FIGURE 4 ). Ocelli yellow. Dorsal surface of fastigium verticis, internal margins of antennal scoket, scape, pedicelli and dorsum of head black, flagellar segments with brownish rings ( Figs. 3C View FIGURE 3 , 4C–D View FIGURE 4 ). Tegmina black brown with apieces pale ( Figs. 1H–I View FIGURE 1 , 2G–H View FIGURE 2 ). Disc of pronotum with irregularly yellowish brown spots; mesonotum, metanotum and dorsal surface with short, yellowish brown stripes ( Fig. 4B, F View FIGURE 4 ). Abdominal sternites, basal half of femora, apical half of tibiae and tarsi yellowish brown ( Fig. 4A–E View FIGURE 4 ).
