Abstract

The Brazilian scarab beetle genus Microchilus Blanchard (Rutelinae: Geniatini) is reviewed. Based on examination of type specimens, Microchilus beckeri Martínez is transferred to the genus Leucothyreus becoming L. beckeri (Martínez), new combination; Leucothyreus bucki Machatschke is a new junior synonym of L. beckeri (Martínez). Microchilus is limited to two species, M. beckeri (Martínez) and a new species, Microchilus rodmani Jameson, here described. Characters that circumscribe the genus, biology, and species distribution are discussed.
