Prince Bernhard’s titi monkey, Callicebus bernhardi

The Prince Bernhard’s titi monkey was described in 2002 by van Roosmalen et al., after a specimen collected on the West bank of the lower Rio Aripuanã, Amazonas state, Brazil. One of the authors also had two living juvenile males, obtained along the Rio Mariepauá at Santa Cruz, not far from its confluence with the Rio Madeira.The distribution of the species is probably restricted to the interfluve delineated by the Rios Madeira-Jí-Paraná and Rios Aripuanã-Roosevelt, in the states of Amazonas and Rondônia, Brazil.

The upper and outer surfaces of head, trunk, and limbs are greyish black, on the back mixed with brownish agouti or red-brown; the forehead is not defined from crown and is greyish black to grey; the ears are black with conspicuous whitish tufts; the sideburns, under parts of body, and inner side of limbs are sharply contrasted dark orange; the hands and feet are sharply contrasted white against greyish black lower limbs; the tail is black except for a sharply contrasted white pencil.

The validity of the species is disputed, based on the genetics Auricchio (2010) considers it to be a local colour variant of C. moloch, which is probably correct.
