Euryoryzomys

Euryoryzomys is a genus of rodents in the tribe Oryzomyini of family Cricetidae.^[1] It includes seven species, which are distributed in South America.^[1][2] Until 2006, its members were included in the genus Oryzomys, but they are not closely related to the type species of that genus, and therefore they were placed in a new genus.^[1] They are most closely related to genera like Hylaeamys and Transandinomys; many members of these genera were previously placed in a single species, known as Oryzomys capito.^[1] The genus name, Euryoryzomys, combines the name "Oryzomys" with the Ancient Greek word eurus "broad", referring to the broad range in distribution of the genus.^[1]
