Diagnostic characters. Vertex with scale tufts. Male antennae with scape elongate, with a basal dentate projection on inner side; flagellae with shallow sinus covered with two lines of long cylindrical scales arranged opposite to each other. Labial palpi usually longer than two times length of compound eyes diameter; second segment in male obliquely upturned, in female slightly curved. Forewing narrowly elongate, usually with a yellow spot at about basal 1/3 that extends from below costa to dorsum, edged with a scale ridge along its inner margin; discal spot separated or connected.

Male genitalia. Valva with clasper absent; costa with a strongly sclerotized process arising from base, symmetrical or asymmetrical, apart from valva distally; juxta narrowly U-shaped, with stout lateral arms; aedeagus with one to three curnuti; culcita one pair.

Female genitalia. Ductus bursae sclerotized or partly sclerotized, with longitudinal ridges; corpus bursae with an appendix bursae, signum located at posterior part of corpus bursae; ductus seminalis originating from middle of corpus bursae.

Etiella is similar to Pima Hulst, 1888 in the forewing usually having a white subcostal streak and the labial palpi upturned obliquely. It can be distinguished by the forewing having a yellow spot edged with a scale ridge, the costa not furcate distally but with a heavily sclerotized basal process in the male genitalia, and the ductus bursae shorter than the corpus bursae and with an appendix bursae in the female genitalia. In Pima the forewing does not have a spot with scale ridge; the costa is furcated distally but has no basal process in the male genitalia; the ductus bursae is longer than the corpus bursae, and the corpus bursae lacks an apependix bursae.
