SAMPAIO, Ricardo et al. New records of Callicebus cinerascens (Spix, 1823) with an extension of its geographical distribution. Mastozool. neotrop. [online]. 2012, vol.19, n.1, pp. 159-164. ISSN 0327-9383.
The ashy black titi monkey (Callicebus cinerascens; Primates; Pitheciidae) is one of the least known Neotropical primate species occurring in the Aripuanã-Roosevelt and Tapajós-Juruena interfluves in Brazilian Amazonia. Its distribution limits, especially those to the east and south, remain imprecise. In this paper, based on four independent primate field sampling, we present several new occurrences in the south of the C. cinerascens' geographic distribution. The knowledge of existing primates in this area is entirely absent and these recently discovered populations are under severe threat, since the remaining habitats are highly fragmented due to the historical deforestation rates of this area. The results of this study significantly increased the number of records known to C. cinerascens, indicating a considerable extension of the geographical distribution of this taxon.
