Vertex 0.9–1.4× as long as wide; apex narrowly pointed; lateral carinae strongly elevated; median carina incomplete, 1/4–1/2 as long as vertex. Lateral carinae of frons convex (although rectilinear apically) or s-shaped. Thorax. Pronotum with arched or sinuate carinae; hind margin right or acutely angled. Forewing 3.5–4× longer than wide; costa with 11–19 tubercles; Sc+R+M forming very short common stem; fork of Sc+R basad of fork of CuA1+CuA2; r–m1 basad of or at same level as fork MA–MP; nine apical cells. Hind leg: tibia with 0–3 small lateral spines (without large lateral spines); six apical teeth in a row interrupted by a wide gap; 1st tarsomere with 7(–8) apical teeth and no platellae; 2nd tarsomere with 8–9 apical teeth and 6–7 platellae. Male genitalia. Aedeagus: phallotheca with a long, slightly curved, sclerotised spine and sometimes with a shorter, more membranous spine, both arising ventrally near apex; flagellum unarmed.
