          White-footed Tamarin (Saguinus leucopus) is a primate endemic to Colombia whose karyotype is described in this study from a pair of individuals located in the East of Caldas Wild Fauna Rehabilitation Center in Colombia. The blood samples were collected from the femoral vein and anti-coagulated with heparin sodium. The chromosomes obtained by the classic method of culture of lymphocytes as well as Q and G banding. The individuals display 46 chromosomes (2n = 46: 30Bi, 14A); sexual chromosomes XX in female and XY in the male (chimerism 46, XX/46, XY in this last one). An ideogram for the White-footed Tamarin karyotype is proposed. Ample similarities in S. leucopus chromosomes Xy 5 are observed and with human chromosomes Xy 19, respectively. Other partial similarities were demonstrated between chromosomes 1 of both species, S. leucopus 2 and 14 with human 7. The comparison of the size of exonic regions of two genes of S. leucopus and Homo sapiens did not show any difference.
