Range DescriptionThere are two recognized subspecies:
According to Hershkovitz (1966), S. m. martinsi occurs between the Rio Nhamund (left bank), east to the Rio Erepecur, north of the Rio Amazonas. It would appear that the mouth of the Rio Trombetas marks the northern limit, but vila-Pires (1974) extends the distribution north-east to the upper Rio Erepecur. The northernmost record is Cachoeira Porteira on the Rio Trombetas (Rylands et al. 1993).
Saguinus m. ochraceus is believed to occur on the west bank of the Rio Nhamund, possibly extending west to the Rio Uatum, north of the Rio Amazonas (Hershkovitz 1966). The northern limit to its range mighty be the left bank of the Rio Alala (Rylands et al. 1993).
