The New World genus Epimetopus Lacordaire, 1854, is revised, based on the examination and databasing of 2,470 specimens. New collection records are provided for 15 previously described species, and 36 new species are described. The Epimetopus fauna now comprises 56 species, of which 37 are restricted to South America, 17 are only found north of South America, and only two species are known from both areas. Epimetopus ranges from Argentina to Arizona and Arkansas, but there are no records from the Amazon basin. The genus is divided into seven species groups, five of which are newly delineated. High resolution digital images of all primary types are presented (online versions in color), geographic distributions of all species are mapped, and male genitalia of primary types are illustrated. The morphology of the underside of the pronotal hood is described and illustrated for the first time. One new synonomy is proposed, placing E. leechi Rocha as a junior synonym of E. balfourbrownei Rocha. New species of Epimetopus are: E. acuminatus (Guatemala: El Progresso, km. 69 on C. A. 9); E. angustus (Ecuador: Napo, Tena); E. arcuatus (Paraguay: Dep. Concepcion, Arroyo Toro Paso, Unterlauf); E. arizonicus (USA: Arizona, Pajarito Mts., Sycamore Canyon); E. ballatoris (Venezuela: Tachira State, El Tama National Park); E. bifidus (Mexico: Oaxaca, Tapanatepec, 8 mi.
