Figs. 1–8

Vertex with a dark brown oblique band on each side of median line near and parallel to anterior margin, posterior to band another, orange or brown, longitudinal band on disc, between eye and midline, extending posteriorly to middle of lateral margin of scutellum; eyes brown, ocelli semitransparent; clypeus with fuscous arcs. Pronotum stramineous with four longitudinal bands in addition to the longitudinal bands originating from vertex, faint orange or brown, and a brown medial longitudinal line from anterior margin of pronotum to apex of scutellum. Scutellum stramineous. Legs marked with brown. Forewings stramineous or brown, cells bordered with brown, veins paler.

Vertex slightly longer than next to eye, coronal suture nearly 3/4 of vertex, ocellus separated from eye by less than ocellus’ own diameter; clypellus with sides parallel. Pronotum nearly as long as vertex. Scutellum slightly shorter than vertex. Forewing macropterous, outer anteapical cell more than 1/2 length of central anteapical cell, latter non-constricted, inner anteapical cell open basally, claval veins joined at one or two points.

Sternal apodemes at base of abdomen truncate apically.

Male genitalia: Pygofer side parallelogram-like. Valve, subgenital plates fused forming subtriangular plate with apical thirdfree. Style apical process twisted. Aedeagal shaft nearly twice length of connective, slightly curved dorsally in lateral view, gonopore near base of fork, on dorsal margin.

Female genitalia: Hind margin of seventh sternum of female with V-shape median notch.
