A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions (cytochrome oxidase subunit I-subunit II, elongation factor-1α and wingless). Monophyly of the family is strongly supported, as are some of the traditionally recognized subfamilies, with the following relationships: (Coeliadinae + ("Pyrginae" + (Heteropterinae + (Trapezitinae + Hesperiinae)))). The subfamily Pyrginae of contemporary authors was recovered as a paraphyletic grade of taxa. The formerly recognized subfamily Pyrrhopyginae, although monophyletic, is downgraded to a tribe of the "Pyrginae". The former subfamily Megathyminae is an infra-tribal group of the Hesperiinae. The Australian endemic Euschemon rafflesia is a hesperiid, possibly related to "Pyrginae" (Eudamini). Most of the traditionally recognized groups and subgroups of genera currently employed to partition the subfamilies of the Hesperiidae are not monophyletic. We recognize eight pyrgine and six hesperiine tribes, including the new tribe Moncini. © The Willi Hennig Society 2008.
