     We developed the potential distribution models for all three species of primates that are distributed around the Southeastern Mexico (Alouatta pigra, A. palliata and Ateles geoffroyi) which are classified as endangered species. The models and a map of vegetation in which monkeys have been recorded were combined for obtaining the models of expected presence-absence. Then 240 localities around all Southeastern Mexico were chosen and visited for validating presence-absence of species. To date, we have visited 229 localities which had not been visited before in other researches (24 in Quintana Roo State, 67 in Campeche, 8 in Yucatán, 58 in Tabasco, 10 in Chiapas, 31 in Veracruz and 28 in Oaxaca). We have found 144 localities with current presence of some species of primates (30 with Alouatta palliata; 42 with A. pigra, 22 with Ateles geoffroyi, 48 with A. pigra and A. geoffroyi, 1 with A. palliata and A. geoffroyi and 2 with A. pigra & A. palliata sharing the geographic space). We have obtained new records of presence of monkeys by direct observations in 40 places (18 of Alouatta palliata, 13 of Alouatta pigra, 3 of Ateles geoffroyi and 6 of A. pigra and A. geoffroyi together). Our main contribution is new knowledge about the limits of the distribution of primates in Mexico.
