Erythrocebus is a genus of Old World monkey. Both species in this genus are found in Africa, and are known as patas monkeys. While conventionally considered a monotypic genus, a recent review has argued that, for political reasons, the taxon should be split back into distinct species as recognised in the 19th century. The northeast Sudanese population would be moved to E. poliophaeus (described from western Sudan), the author proposing in addition that the subspecies E. p. pyrrhonotus be elevated to full specific status, along with the formerly recognised subspecies E. p. baumstarki for the population in Tanzania, and possibly the old synonym formosa for southwest Ethiopia.
