DistributionRead full entry
Range DescriptionCabrera (1957) described its distribution as the south of the state of Par, possibly entering contiguous parts of the state of Mato Grosso. vila-Pires (1986) was more exact, indicating that it occurs south from the Rio Irir (C. a. argentata occurring to the northconfirmed by Martins et al. 1988), at least as far south as the southern (left) margin of the Rio Peixoto de Azevedo, an eastern tributary of the Rio Teles Pires. Martins et al. (1988) recorded it on the left bank of the Rio Irir, south from its mouth. The southern limits would evidently not be beyond the headwaters and upper Rio Paraguai, approximately 1430'S, where M. melanurus has been registered for a number of localities (Hershkovitz 1977; Vivo 1985). vila-Pires (1986; see also Pimenta and Sillva Jr. 2005) suggested that the Rio Teles Pires marks the western limit of its range. Martins et al. (1988) indicated that C. emiliae is limited to the west (left) bank of the lower Rio Irir, with an undescribed C. argentata subspecies occurring between the Rios Irir and Xing. These authors also reported their belief that no marmoset occurs east of the Rio Xing above the mouth of the Rio Irir. The distribution of C. emiliae has been confused somewhat by its alignment with a similar, if slightly darker, form in the state of Rondnia by Vivo (1985), referred to here as Mico cf. emiliae (also discussed in the text on M. melanurus).
