Nothopteryx.
Adults. Antennae of males simple; shortly simply-ciliate. Face smooth.
Wingspan 30–36 mm. Forewings 1.7–1.8 times as long as wide. The outer margin of the forewing convexly curved. Forewings greyish whitish and blackish sprinkled, or greyish ochreous; with a clear discal mark, or without a clear discal mark; with a distinct median band (the band dark), or without a median band. Hindwings plain; whitish or pale ochreous-grey; with a clear discal mark (this grey); transversely lined (with several faint grey lines, or just a posterior one).
Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 separate.
Posterior tibiae of males 2-spurred (females also?).

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
