Description. Macropterous male. See generic description; only additional details provided here. Holotype, length 10.50; maximum width 6.13. Paratypes (n = 2), length 10.45–10.56 (mean = 10.50); maximum width 6.00–6.04 (mean = 6.02). Overall coloration dorsally dark brown (Fig. 1); head and pronotum yellowish, but profuse, dark brown punctation gives a dark overall appearance; with three large, irregular, dark spots between eyes in anterior quarter adjacent to impunctate margin. Venter with yellow perimeter; ventral surface of embolium yellow; coxae yellow, suffused with medium brown; trochanters, femora, tibiae yellow; tarsi mostly yellow, but dark brown distally. Prosternum medium brown, with yellow wedge-shaped midventral carina; propleura dark brown; meso- and metasternum medium brown; abdominal sterna mostly medium brown with yellow lateral band.
Head length 1.64, maximum width 3.53, synthlipsis at posteromesal corner 1.64, with four pairs of setal rosettes bordering inner margin of eyes, fifth pair further mesad and slightly ventrad to anterior margin. Antennal proportions 5:6:14:10.
Pronotum broad, 2.7 times as wide as long; length at midline 2.05; maximum width at posterolateral corners 5.45; posterolateral corners broadly rounded, with pronounced bulge above wing base. Scutellum dark brown, triangular, with yellow apex, with distinctly sinuate posterolateral margins, almost 1.5 times as wide as long, width 3.53, length 2.30. Hemelytra dark brown with claval commisure length 1.52. Embolium with anterolateral angle gently arcuate, yellowish anterior band gradually narrowing posteriorly and becoming obsolete near costal fracture, with triangular mesal incursion of yellow into dark brown at level of scutellar apex, yellow area in embolium with dark brown punctation except immediately along costal margin; hemelytron length (chord distance) 7.79, width at scutellar apex 3.24. Leg measurements as follows: foreleg, femur 2.25, tibia 1.60, tarsus 0.49; middle leg, femur 2.87, tibia 2.30, tarsomeres 1–3, 0.29, 0.49, 0.53; hind leg, femur 3.65, tibia 4.06, tarsomeres 1–3 0.37, 0.74, 1.19.
Posterior margin of mediosternite III straight, IV concave, V deeply concave and asymmetrical, VI – VIII irregularly straight to broadly rounded. Posterior margin of laterosternite V with deep medial convexity. Aedeagus elongate, linear, left margin nearly straight in basal ¾, angled to apex in apical 1/4, gently arcuate along right margin, with distal acumination on right half, finely granulate laterally; parameres small, symmetrical, rounded distally; pygophore punctate, with long setae (Fig. 7).
Macropterous female. Paratypes (n = 2), length 10.68–10.96 (mean = 10.82); maximum width 6.02–6.22 (mean = 6.12). Similar to male in general structure and coloration; pad of hairs on middle tibia reduced; posterior margin of mediosternite III – VI straight; posteromedial corner of laterosternite V with strong, posteriorly-directed acuminate, digitate lobe; subgenital plate broadly rounded; valvulae extending beyond apex of subgenital plate (Fig. 8).
