Original description, Meyrick 1906
Chereuta, n.g.
Head smooth; tongue developed. Antennae 2/3 – 4/5, in male simple or minutely ciliated, basal joint moderate, without pecten. Labial palpi very long, recurved, second joint thickened with appressed scales, terminal joint as long as or longer than second, slender, acute. Maxillary palpi obsolete. Posterior tibiae smooth, with expansible whorls of rough scales at origin of spurs. Forewings with 1 b furcate, 2 from 4/5. 7 to costa or apex, 8 absent, 11 from middle. Hindwings somewhat over 1, trapezoidal, apex obtuse, termen sinuate, cilia ½ - 4/5; 3 and 4 connate, 5 parallel, 6 and 7 connate or stalked, 8 anastomosing with upper margin of cell towards base.
Type C. tinthalea. Allied to Catoryctis, from which it differs especially by the structure of vein 8 of hindwings. The species are relatively small dark insects, with a tendency to metallic colouring.
Sydney and Shoalhaven, New South Wales, in October and January; two specimens. Characterized by the strong white irroration and metallic cilia.

Synonymic description, Turner 1929
