The black-browed titi monkey, Callicebus caligatus

Callicebus caligatus was described in 1842 by Wagner as Callithrix caligata from one specimen collected at Borba on the Madeira River, not far from its confluence with the Amazon and a second specimen from the Solimoes River. It was described as being : “diluted brownish, hairs of dorsum with black and yellowish rings, ventrum coppery-red; hands and forehead black”. Gray described in 1866 a comparable species, Callithrix castaneoventris, that is considered to be a synonym for Callicebus caligatus.

Its distribution is restricted to Brazil.
