Scientifically described and named in summer 2010, the world´s newest species of monkey is the Caquetá titi (Callicebus caquetensis). The size of a cat, it sports reddish-grey fur but lacks the distinctive white bar on its brow that most other allied species of titi possess. Discovered by Dr Thomas Defler, Dr Marta Bueno, and undergraduate student Javier Garcia from the Universidad Nacional de Colombia, with support from Conservation International, it inhabits the Colombian Amazon region close to the borders with Peru and Ecuador.
