The terminal line is a series of irregular white and black dashes. The fringe is primarily gray-brown but with a large white spot about one-third the distance up from the inner angle. The hindwing is white lightly suffused with yellow-brown. Wing length from base to apex in one selected individual 8 mm.

Ponometia cuta

Ponometia cuta is similar to heonyx. However heonyx lacks a dark, triangular mark reaching from the costa to the reniform. Indeed marks on the costa are entirely absent in heonyx. The fringe of cuta has a large white patch just upward from the inner angle along the outer margin. A white patch is absent in heonyx.

The dark marking in the outer half of the forewing is roughly s-shaped in dorneri with a large, triangular white patch stretching inward from the outer margin to the position of the subterminal line. The dark markings are darker in color than in cuta.
