Abstract
The genus Oethecoctonus of North America is revised. Three species are recognized, of which two are new to science: O. ophrynopus and O. pleuralis. O. oecanthi (Riley), the type-species of the genus, is redescribed and figured. A generic diagnosis of Oethecoctonus and key to North American species are given. The higher classification and world distribution of Oethecoctonus species are discussed.
