Ponometia heonyx

Ponometia heonyx is similar to cuta. Ponometi cuta has a dark, triangular mark reaching from the forewing costa to the reniform. All dark markings are absent from the forewing costa of cuta. The fringe of heonyx is uniformly brown, but there is a white patch in the fringe of cuta.

The outer half of the forewing of heonyx is uniformly brown. The dark marking of the forewing of dorneri is roughly s-shaped with a large, triangular mark reaching nearly to the position of the suterminal line.
