Botucaraitherium is an extinct genus of prozostrodontian cynodonts from the early Norian Riograndia Assemblage Zone in the Candelária Formation of the Paraná Basin in southeastern Brazil.[1] It is known from a single type species, Botucaraitherium belarminoi. The genus name is derived from the Botucaraí Hill, which dominates the landscape of Candelária, Rio Grande do Sul. The species epithet honors Belarmino Stefanello, a volunteer at the Museu Municipal Aristides Carlos Rodrigues, who found the fossil.[2]
