“Chiquitanos titi monkey”

van Roosmalen and van Roosmalen (2014) mention a new, undescribed species from the Chiquitanos area along the Rio Paraguay. A holotype is supposed to be in the AMNH, and a living specimen in the Rio de Janeiro Primate Center. Except for its grey ears, the Chiquitanos titi monkey is a very light coloured species, but less so than the neighbouring C. pallescens.
