Milton’s titi monkey, Callicebus miltoni

Milton’s titi monkey, Callicebus miltoni, was described in 2014 by Dalponte et al., based on specimens collected between the Ríos Roosevelt and Aripuana, in the Brazilian states of Amazonas and Mato Grosso. The species was named in honor of Dr. Milton Thiago de Mello in recognition of his contribution to development of Primatology.

The new species was described as having “dark-ocher (orange-brown) sideburns; forehead with a white (light gray) stripe contrasting with the dark agouti-gray crown; ears colored similarly to crown, but with white (light gray) edges and a discrete white (light gray) tuft; superior part of the body, flanks and external sides of members a uniform gray-agouti, which extends to approximately 1/10th of the tail on the anterior-superior portion; white (light gray) hands and feet, in the same tone of the forehead stripe and ear edges, contrasting with the gray-agouti of the external parts of the members; throat in the same tone as sides of the face (dark-ocher); chest, belly and internal parts of the members light orange, visibly contrasting with the dark orange of the sideburns and throat; tail (except 1/10th of the anterior-superior portion) uniformly light orange, though the individual hairs show two stripes, one basal light orange and one distal reddish-orange”.

The geographic distribution of Milton’s titi monkey coincides with the interfluvial region of the Roosevelt
and Aripuanã rivers, states of Mato Grosso and Amazonas, Brazil.
