Description
Male. Body black or dark brown (Figs 1, 5). Face black with brown eyes, ocelli and upper lip yellowish brown. Antennae black, with apical segments pale yellow. Sternites and legs reddish brown or black, tarsal pulvilli pale (Figs 2, 6).
Vertex punctate, with a small foveola in dorsal view, which is exposed to the excision of pronotum in anterior margin (Fig. 27). Face punctulate, ocelli distinct. Pronotum transverse, anterior margin with a U-shaped excision in the middle, lateral corners of the indentation incrassate and upturned; lateral margins convex and the widest point below the middle; hind margin straight; anterior 1/3 of pronotum weakly depressed and the floor granular, with two rounded grooves, remaining surface punctate and with two tubercles medially (Fig. 27). Tegmina and wings fully developed (Figs 28–29) and reaching or extending beyond the end of abdomen (Fig. 1), sometimes mutilated. In brachypterous form, tegmina and wings reduced (Figs 37–38) with tip just reaching the hind margin of segment two to segment four of abdomen (Fig. 5), sometimes mutilated terminally. Caudal edge of the hind wing wave-shaped (Fig. 38). Anterior ventral margin of front femur with 0–2 spines and distal spine absent, hind margin with a large distal spine. Abdominal tergites densely punctate, the punctations denser caudally, anterolateral corners without holes. Caudal angles of T6 rounded; lateral margins of T7 smooth, posteriolateral angles extended caudally and with subacute apex (Fig. 30). Abdominal sternites densely punctate, hind margin of S7 concave (Fig. 31) and subgenital fig slightly exposed. Supra-anal fig densely punctate, the surface coarser than on abdominal tergites; hind margin crenulate, with 7–10 small teeth in middle, caudal angles small, similar to or slightly bigger than the largest one between them (Fig. 32). Cercus fin-shaped, setaceous ventrally, dorsal surface without setae (Fig. 32). Posterior part of subgenital fig flabellate (Fig. 33). Male genitalia. Genital phallomere L1 well developed but slightly sclerotized (Fig. 34); L2vm rod-like, L2d with an elongate projection at the apex (Fig. 35); R2 developed and hook-shaped (Fig. 36).
Female. Similar to male, but hind margin of S7 rounded. In all specimens observed, the anterior margin of pronotum with an excision. In brachypterous form, tegmina and wings also reduced similar to males.
Nymph. Body black and punctate, with two yellowish brown marks on the mesonotum and metanotum without marks (Figs 3–4, 7–8).

Male, body length: 29.1–32.0 mm; pronotum: length/width: 6.5–6.9/9.6–10.5 mm; width of excision of anterior margin of pronotum: 1.7–2.0 mm; distance between disc tubercles: 1.5–2.0 mm; tegmen: 22.7–26.4 mm. In brachypterous form, body length: 28.5–35.5 mm; pronotum: length/width: 6.8–7.1/9.8–11.3 mm; width of excision of anterior margin of pronotum: 2.0–2.5 mm; distance between disc tubercles: 1.9–2.5 mm; tegmen: 13.5–16.7 mm.
Female, body length: 29.7–32.6 mm; pronotum: length/width: 6.5–7.0/10.1–10.3 mm; width of excision of anterior margin of pronotum: 1.7–2.0 mm; distance between disc tubercles: 1.9–2.0 mm; tegmen: 23.0–26.8 mm. In brachypterous form, body length: 32.0–32.5 mm; pronotum: length/width: 6.1–7.1/9.6–11.1 mm; width of excision of anterior margin of pronotum: 1.6–2.5 mm; distance between disc tubercles: 2.0–2.4 mm; tegmen: 12.6–16.0 mm.
