Background Captive primates are often maintained in groups without geographic origin or genetic heritage information. This could lead to an incorrect assignment of species, which could result in an inadequate management of the colonies. Methods We present a cytogenetic protocol adapted to be successfully used in an accurate taxonomic diagnosis of non-human Primates (Platyrrhini), including: lymphocyte culture, G- and C-banding, meiosis and FISH. Results Using classical cytogenetic diagnosis, the species status was determined in 541 Platyrrhini individuals. Of these, 99 were previously erroneously sexed or assigned to a different species using only morphological characteristics. Conclusions The cytogenetic results highlight the relevance of the genetic characterization of primates both in captivity and in the wild. These techniques had been used in our research group for more than thirty years in different research projects, not only for characterizing hundreds of primates, but also different for topics regarding Primates genomes and evolution.
