The species M. nemorivaga corresponds to the grey brocket deer that occupies the Amazon region. Based on previous studies, the current taxonomic classification of the species presents inconsistencies, which suggest the presence of more than one species within what is now classified as M. nemorivaga. In this way, the present research project aims to contribute with the taxonomy of the Mazama genus, by collecting a specimen in its type locality (Cayenne, French Guiana). Characterizing the morphological specimen, Cytogenetic and molecular, allowing the comparison of the species under study with other specimens used in publications, in order to know the differences between them and to review the taxonomy of the species. For this, a specimen was collected in the locality of the species (French Guiana), characterized by traditional morphology techniques. (craniomandibular measurements, biometric measurements, skin coloration), geometric morphology, as well as by cytogenetic analyzes (Band G, C-band, conventional Giemsa staining and Ag-NOR staining, telomeric FISH) and molecular (phylogenetic analyzes of mitochondrial genes Cyt b of 920 bp, IOC I of 658 bp, D-loop 610 bp). The results of the cytogenetic and molecular characterization showed a clear grouping of M. nemorivaga topotype along with specimens from the Amapá region, constituting the northern clade (French Guiana and Amapá). In addition, it is suggested the existence of three distinct species, based on differences in relation to the topotype of the species. One occurred in the eastern Amazon, above the Amazon River (Amapá and French Guiana), another in central Amazonia (Mato Grosso, Pará and Maranhão) and another one in western Amazonia (Acre and Rondônia). The presence of hairs in the tarsal region was identified as one of the morphological characters that can be used to diagnose the species in relation to other members of the genus.
