Diagnosis.
Combining the following characteristics, this species is easily distinguished from other species of this genus: 1) body yellowish brown; 2) hind margin of subgenital plate wavy; 3) male genitalia L2 without spine at end, only a small protuberance; 4) the distal part of R1H broad, slightly sclerotized and hyaline, the end with an elongate and curved spine inward.
Description.
Coloration. Body yellowish brown; ocelli white; hind margin of subgenital plate nearly brown (Fig. 5A, B View Figure 5 ).
Male (Fig. 5A, B View Figure 5 ). Body length including tegmen: 30.5-32.7 mm; body length: 27.1 mm; pronotum length × width: 6.2-6.6 mm × 7.7-8.2 mm; tegmina length × width: 24.9-25.4 mm × 8.0-8.2 mm. Head and thorax. Vertex unexposed. Interocular space slightly wider than the interocellar space, shorter than the distance between antennal sockets (Fig. 5C View Figure 5 ). Antennae longer than the body. Pronotum subelliptical; anterior margin straight, hind margin slightly convex; the widest point near the midpoint (Fig. 5D View Figure 5 ). The posterior-lateral angles of metanotum with symmetrical and small projections (Fig. 5E View Figure 5 ). Tegmina and wings well developed, surpassing the tip of abdomen (Fig. 5A, B, G, H View Figure 5 ). Tegmina with ScP strong, posterior branch of R not reaching the end of tegmina (Fig. 5G View Figure 5 ). Front femur of type A2 (Fig. 5F View Figure 5 ). Mid- and hind legs with strong spines. Hind metatarsus longer than the remaining segments combined. Pulvilli present on 1-4 tarsal segments, claws symmetrical and unspecialized, arolium small (Fig. 7C View Figure 7 ). Abdomen. First tergite of male abdomen with visible gland, setose gland curved, and directed toward left, right, and down (Fig. 5E View Figure 5 ). Supra-anal plate rectangular, lateral margin slightly shrunken inward; middle part of hind margin concave. Paraprocts (pp.) long, strip-shaped. Cerci robust (Fig. 5I View Figure 5 ). Subgenital plate nearly square; the hind margin wavy. Styli symmetrical and apically rounded (Fig. 5K View Figure 5 ). Genitalia (Fig. 5J View Figure 5 ). L1 membranous with pubescence. L4C thin and ribbon-like, the inner margin with a long projection of densely microtrichia. L2 irregular, the distal part with a small projection. L3 unciform and well sclerotized, the basal part bifurcated. The distal part of R1H broad, slightly sclerotized and hyaline, the end with an elongate and curved spine inward. The distal part of R1G with a curved, strong spine inward.
Female. Unknown, possibly brachypterous.
Etymology.
The species epithet is from the Latin word " undulata ", in reference to the way hind margin of subgenital plate.
