An extension of the known geographic distribution of Sapajus cay (Illiger, 1815) (Primates, Cebidae) in southwestern Brazilian Amazonia

Abstract

We update the geographic distribution of Sapajus cay in the south-central, southeast, and western portions of Mato Grosso state, Brazil, and extend the distribution of this species north to the Cabixi River at the border with the state of Rondônia. Data were obtained from field surveys. We observed individuals of S. cay in highly fragmented forests which have been impacted by the deforestation over the past 50 years. This is an alarming situation for the conservation of the region’s fauna.
