Celaenorrhinus is a genus of skipper butterflies which are commonly termed sprites. An alternate name is "flats", for their habit of holding their wings flat when resting, but this is also used for related genera. They belong to the spread-winged skipper subfamily (Pyrginae), and therein are the type genus of tribe Celaenorrhini.

Celaenorrhinus species are found in most tropical regions. However, rather than a monophyletic genus the group appears to be a paraphyletic asssemblage, and will probably be split up in the future.

The following is a description of the genus from an old work and may not account for more recent taxonomic changes.

This diagnosis has been made from bleached wings of both sexes of the "Hesperia" leucocera of Kollar, from Simla, and of the "Papilio" eligius of Cramer from the Amazons, for the specimens of which latter I am indebted to Dr. O. Staudinger. All the species of the genus settle with wide outspread wings, which at once distinguishes them in life from the genus Notocrypta, mihi, the species of which rest with wings folded upright over the back. C. leucocera in the Western Himalayas is markedly crepuscular, I have seen specimens over and over again flying up and down a short distance of the bed of the Simla river with immense rapidity, so fast that the eye can hardly follow them, settling on a leaf for a second and then flying off again, long after the sun has set. All that are known to me have the hindwing more or less spotted. C. eligius, Cramer, was described from Surinam in South America, and Felder states that he has received a specimen from Venezuela.
