Diagnosis.
Combining the following characteristics, this species is easily distinguished from other species of this genus: 1) body dark reddish brown; 2) pronotum smooth without punctures; 3) the hind margin of subgenital plate arcuate; 4) the inner margin of L4C with serrate auriculate projection; 5) the distal part of R1G with a slender spine; 6) anterior arch with furrow; 7) the surface of basivalvulae flat.
Description.
Sexual dimorphism present. Coloration. Body reddish brown to dark reddish brown; ocelli white; cerci and styli brown to black (Fig. 4A-D View Figure 4 ).
Male (Fig. 4A, B View Figure 4 ). Body length including tegmen: 25.4-30.9 mm; body length: 18.2-21.9 mm; pronotum length × width: 4.6-5.9 mm × 5.8-7.0 mm; tegmina length × width: 22.5-26.9 mm × 6.3-8.2 mm. Head and thorax. Vertex slightly exposed. Interocular space slightly wider than the interocellar space, shorter than the distance between antennal sockets. Antennae longer than the body (Fig. 4E View Figure 4 ). Pronotum subelliptical; anterior margin slightly concave, hind margin slightly convex; the widest point near the midpoint (Fig. 4F View Figure 4 ). The posterior-lateral angles of metanotum with symmetrical and small projections (Fig. 4J View Figure 4 ). Tegmina and wings well developed, surpassing the tip of abdomen (Fig. 4A, B, G, H View Figure 4 ). Tegmina with ScP strong, posterior branch of R not reaching the end of tegmina (Fig. 4G View Figure 4 ). Front femur of type A2 (Fig. 4I View Figure 4 ). Mid- and hind legs with strong spines. Hind metatarsus longer than the remaining segments combined. Pulvilli present on 2-4 tarsal segments, claws symmetrical and unspecialized, arolium small (Fig. 7B View Figure 7 ). Abdomen. First tergite of male abdomen with visible gland, setose gland curved and downward (Fig. 4J View Figure 4 ). Supra-anal plate rectangular, lateral margin not shrunken inward; middle part of hind margin slightly concave. Paraprocts (pp.) long, strip-shaped. Cerci robust (Fig. 4L View Figure 4 ). Subgenital plate nearly square; the hind margin arcuate. Styli symmetrical and apically rounded (Fig. 4K View Figure 4 ). Genitalia (Fig. 4M View Figure 4 ). L1 composed of a elongate sclerite and membrane bearing pubescence. L4C thin, ribbon-like, the inner margin with serrate auriculate projection. L2 irregular, near distal part with two small spines and the end with one long spine inward. L3 unciform and well sclerotized, the basal part bifurcated. The distal part of R1H broad, the inner margin bifurcated with two small spines. The distal part of R1G with a curved, long spine inward.
Female (Fig. 4C, D View Figure 4 ). Body length: 22.2 mm; pronotum length × width: 6.1 mm × 7.4 mm; tegmina length × width: 5.8 mm × 5.2 mm. Head and thorax. Interocular space slightly wider than interocellar space and the distance between antennal sockets (Fig. 4D View Figure 4 ). Pronotum subelliptical, the widest point near hind margin; anterior margin and hind margin straight (Fig. 4C View Figure 4 ). Tegmina and hind wings reduced. Tegmina squamiform, reaching the first tergite of abdomen; the outer margin oblique (Fig. 4C View Figure 4 ). Hind wings small, lobe-like. Hind metatarsus approximately equal to the remaining segments combined. Pulvilli present on 2-4 tarsal segments, claws symmetrical and unspecialized, arolium smaller than male. Abdomen. Hind margin of tergum X (TX) with median invagination, and with a membranous line inside; cerci thick and not upturned (Fig. 4N View Figure 4 ). Genitalia (Fig. 4N View Figure 4 ). The base of first valve (v.I.) with dense microtrichia. First valvifer (vlf.I) thin. Second valve (v.II) with strip-like sclerite. Posterior lobes of valvifer II (p.l.) irregular, the outer margin disconnected with laterosternite IX (ltst.IX). Laterosternite IX broad and irregular. Anterior arch (a.a.) with furrow, and two symmetrical projections near outer margin, inner margin with microtrichia. Spermathecal plate (sp.pl.) broad, connected to basivalvulae (bsv.) by membrane. Spermathecal opening (sp.o.) located at the base of basivalvulae. Spermatheca branched, the leading duct short, the branching duct relatively long, and the end capsule unknown (Fig. 7E View Figure 7 ). Basivalvulae reniform, surface flat and margin with sparsely microtrichia. Laterosternal shelf (ltst.sh.) symmetrical.
