Primates, Pitheciidae, Callicebus coimbrai Kobayashi and Langguth, 1999: new localities for an endangered titi monkey in eastern Sergipe, Brazil

Abstract

Coimbra-Filho’s titi monkey, Callicebus coimbrai Kobayashi and Langguth, 1999, appears to be endemic to the northern Atlantic Forest, south of the lower São Francisco River in east of the state of Sergipe and north-east of the state of Bahia. This study presents 13 new records of the occurrence of the species in the São Francisco and Japaratuba basins of eastern Sergipe, extending its range in the state over a distance of some 40 km. This represents an important advance in the known range and total number of populations of this endangered primate.
