Mid femora without ventral spinules, mid tibiae with 3–4 pairs dorsal spurs and 5 pairs of ventral spurs. Hind femora with about 5–9 ventral spinules on each side, hind tibiae armed with 6 external dorsal spines and 6 internal dorsal spines, with 3 apical spurs on each side. Tegmina well developed, C indistinct, Ra with 3 branches near apex, Rs with 3 branches, Ma bifurcated near base, Mp+CuA1 with 5 branches, CuA2 bifurcated. Ra of hind wings single, Rs arising in the middle and with 3 branches. All abdominal tergites with a prominent median keel. Tenth abdominal tergite and epiproct fused with each other ( Fig. 11 ), Paraprocts with hooks curved upward. Cerci short and solid, conical. Subgenital plate triangularly notched at apex and with long styli ( Fig. 13 ).

Female. Venation of elytra and hind wing as male, but between Mp+CuA1 and CuP of elytra with 4 branches and without stridulatory mechanism. Seventh abdominal tergite produced in middle of hind margin into a triangular process ( Fig. 14 ). Subgenital plate short, with truncate hind margin. Ovipositor reduced, upper valva with segmented appendages.

Coloration of body yellowish brown varied with some black and light tones. Occiput blackish with 5 irregular longitudinal light stripes, pronotum pitch black, with a distinct testaceous band along the middle in prozona. Legs light with knees darkened. Tegmina shiny, blackish with green costal area. Appendages of valva whitish.

Holotype Male: Heixuangou, alt. 2000m, Labahe Reserve, Tianquan county, Sichuan Province, 27.VII.2007, leg. Liu Xian-Wei et al.; Partypes: 2 females, same data as in holotype.

Etymology. The name refers to the ornate coloration of the species in life.
