The White-collared titi monkey, Callicebus torquatus

The White-collared titi monkey was one of the first titi monkeys that was described. In 1807 the Count von Hoffmannseg described it as “the gracious ruffed monkey” Callitrix torquata.

Through the years there has been much discussion on its identify and origins, and its relationship to two other species that had been described in the same period, amicta and lugens. In literature, other taxa that first were considered te be subspecies of Callicebus torquatus are often referred to as “Callicebus torquatus“, meaning that some of the information should be handled with care (on this website I have always tried to mention the actual identification of the taxon).

Callicebus torquatus is a dark coloured titi monkey with whitish, buffy orange to rufous hands, with or without mixture of blackish hairs. Its tail is blackish. The chest and belly are reddish or reddish brown, the hairs of the back and sides weakly banded to uniformly reddish brown. The throat collar is weakly defined, sometimes absent.

Its distribution range covers the state of Amazonas, Brazil; left (north) bank of Rio Solimões/Rio Japurá, west as far as Río Apaporis/upper Río Vaupés. The range in the north is delineated by the Rio Negro/Rio Uaupés, east at least as far as the town of Codajás, maybe even as far as the town of Manacapurú, both on the north bank of the Rio Solimões, west of Manaus.
