Morphology. Head. Vertex 1.0–1.5× as long as wide, produced before eyes by 1/4–1/2 of an eye length; apex broadly pointed; caudal border u-shaped; lateral carinae strongly elevated; median carina incomplete, 1/4–1/2 as long as vertex. Frons 1.1–1.5× longer than wide, position of maximum width distinctly ventrad of centre of frontoclypeal suture; lateral carinae slightly s-shaped, slightly elevated, lateral margins foliaceous, concealing base of antennae; median carina complete. Frontoclypeal suture semicircular, median part reaching at least lower margin of antennal scape; postclypeus with well developed lateral carinae and median carina; anteclypeus with well developed median carina. Thorax. Pronotum with sinuate carinae; hind margin rectangular. Forewing less than 3× longer than wide; costa with 13–15 tubercles; concavity at costal border absent; Sc+R+M forming common stem; fork of Sc+R basad of fork of CuA1+CuA2; r–m1 basad of fork MA–MP; position of icu at CuP distad of or at same level as apex of clavus; eight apical cells. Hind leg: tibia with 1–2 small lateral spines (without large lateral spines); six apical teeth in row interrupted by narrow gap; 1st tarsomere with 8–9 apical teeth and 1–2 platellae; 2nd tarsomere with 9(–10) apical teeth and 7(–8) platellae.
