Abstract: Catoclastus Solier, 1851 (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), a genus endemic to Peru, is revised. Based on morphology and examination of type specimens, Catoclastus jaumesi Soula, 2010 is a new synonym of C. chevrolatii Solier, 1851, while Catoclastus rabinovichi Martínez, 1971 is transferred to the genus Mecopelidnota Bates, 1904, leading to Mecopelidnota rabinovichi (Martínez) as a new combination. Characters that characterize the genus, natural history, and distribution data are given. Implications and problems associated with intraspecific variability of C. chevrolatii are discussed. As a result of our research, the genus is considered monotypic and endemic to western Peru.
