Feltia gypaetina can be distinguished from other South American species of Feltia by the following combination of characters: the forewing ground color varies from reddish brown to grayish brown, but with a remarkable light brown area along the subcostal margin (Figs 32–33); postmedial line is present as a light brown band bordered by two dark brown sinuate lines (Figs 34–35); the male antennae are slightly bipectinate and bifasciculate, with anterior rami two times longer than posterior rami (Figs 43–44); the male genitalia vesica is between two and two and a half times as long as the aedeagus, with a basal twirl and one apical diverticulum (Figs 47, 52); the female genitalia appendix bursae is tubular and distally tapers, being slightly longer than the corpus bursae (Figs 54–55); and the corpus bursae is oval and without signa (Figs 54–55).
