The validity of two forgotten names, Eryphus Klug, 1829 and E. rubricollis Klug, 1829, is discussed. The former is considered a nomen oblitum and synonymized with Eriphus Audinet-Serville, 1834, a nomen protectum; the latter is revalidated and Eriphus purpuratus Chevrolat, 1862 is considered a junior synonym of Eriphus rubricollis (Klug, 1829). A lectotype is designated to Eryphus rubricollis Klug, 1829. The date of the work where Eriphus Audinet-Serville, 1834 was described is corrected. A new genus is described in Dichophyiini Gistel, 1848 to include the species currently allocated in Eryphus sensu Napp & Martins (2002). The dates of publication of genera and species described by Fairmaire & Germain (Révision des Coléoptères du Chili (suite)) are corrected.
