The Atlantic Forest of the state of Rio de Janeiro was the habitat of six native primate species: Callithrix aurita, Leontopithecus rosalia, Alouatta guariba clamitans, Brachyteles arachnoides, Callicebus nigrifrons and Cebus nigritus; a seventh species, Brachteles hypoxanthus, possibly occurs in the state. In the literature, the number of non-native primate species for the state was less (three) than the native species (six or seven). Our study reviews the list of primate species, both native and non-native, within the state of Rio de Janeiro and discusses the possible impacts of the introduced primates on the native fauna. Using data from the literature, personal communication with experts, data from Brazilian Federal datasets (Linha Verde and CETAS), and specimens deposited in scientific collections of museums, we recorded 17 primate species with at least one record within the state of Rio de Janeiro. At least eight taxa can be considered non-native to the state. Conservation implications for native fauna may include food resource depletion and competition, hybridization, and disease transmission. Some of these effects were already recorded on the native fauna. We believe the removal of non-native primate species from the state is necessary in order to preserve native fauna regardless of political and ethical issues.
