Frons 1.1–1.5× longer than wide; maximum width distinctly dorsad of centre of frontoclypeal suture; lateral carinae convex (although rectilinear apically); slightly elevated, lateral margins foliaceous, concealing base of antennae; median carina complete. Frontoclypeal suture semicircular, median part not reaching lower margin of antennal scape; postclypeus with well developed lateral carinae and median carina; anteclypeus with well developed median carina. Thorax. Pronotum with arched carinae; hind margin obtusely angled. Forewing 3.5–4.0× longer than wide; costa with ~8 tubercles; concavity at costal border present; no Sc+R+M stem, Sc+R forming common stem, M emerging separately from basal cell; fork of Sc+R basad of fork of CuA1+CuA2; r–m1 distad of fork MA–MP; position of icu at CuP distinctly distad of apex of clavus; 9–10 apical cells.
