The study of the type material of Onthophagus viviensis dOrbigny, 1905 and Onthophagus laevatus dOrbigny, 1902 (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) revealed that these two species described from Africa are instead two South American Onthophagus Latreille, 1802. The male of O. viviensis is described for the first time and its systematic position within the O. curvicornis species complex of American Onthophagus is discussed. In addition, Onthophagus laevatus new synonym is established as junior subjective synonym of Onthophagus curvicornis Latreille, 1812. Photographs of the type material examined, pictures of the body and male genitalia of O. viviensis and O. curvicornis, and an updated map of the geographic distribution of these two South American species is provided. A neotype is designated for O. curvicornis and lectotypes are designated for O. laevatus, O. minax Kirsch, 1866 and O. viviensis.
研究 Onthophagus viviensis d'Orbigny, 1905 和 Onthophagus laevatus d'Orbigny, 1902 的模式标本（鞘翅目：金龟科：金龟亚科：Onthophagini）表明，这两个描述于非洲的物种实际上是两个南美洲的 Onthophagus Latreille, 1802 物种。首次描述了 O. viviensis 的雄性，并讨论了其在美洲 Onthophagus curvicornis 种复合体中的系统位置。此外，建立了 Onthophagus laevatus 的新同物异名，作为 Onthophagus curvicornis Latreille, 1812 的次同物异名。提供了检查的模式标本照片、O. viviensis 和 O. curvicornis 的身体和雄性生殖器图片，以及这两个南美洲物种地理分布的更新地图。为 O. curvicornis 指定了一个新的模式标本，并为 O. laevatus、O. minax Kirsch, 1866 和 O. viviensis 指定了选模式标本。
