The natural distribution of genus Callithrix still has many gaps, and the limits of distribution of each species are remaining unclear. This paper presents new information and suggestion about the distribution of Callithrix, and its hybrids, in Minas Gerais. The data collection was made using different information sources: online research, questionnaire, literature review, photographic record and in loco inspections. From 437 responses of questionnaire, 11.4% indicated the presence of some hybrid Callithrix in Minas Gerais. The distribution of hybrids accompanies land routes used to wildlife traffic. Our findings also suggested that the distribution of the hybrids Callithrix coincides with some endangered species, such as C. aurita and C. flaviceps. During the course of research the authors received 98 photographic records, 17 cities were visited and a total of 106 scientific searches were found. With respect to the geographical distribution of Callithrix species, the data suggested that C. penicillata and C. geoffroyi has been introduced in several regions of Minas Gerais. However, it is believed that there might also be a natural expansion of the C. penicillata toward the Atlantic Forest. The C. jacchus is the only species of Callithrix that does not occur naturally in Minas Gerais, but it is widely introduced in the state. The data also indicated that C. penicillata and C. geoffroyi were partially sympatric with all species of the genus. The C. aurita was partially sympatric with C. flaviceps, and C. kuhlii was completely allopatric with both C. aurita and C. flaviceps. The data presented are of great importance for future studies of biodiversity conservation, once the state of Minas Gerais has a great diversity of species of Callithrix, and the reports of introducing species and hybridization are increasingly frequent. However, there are still issues to be verified in studies in loco, once it was not possible to verify the complete relationship between the species in each region discussed.
