The Pitheciidae are one of the five families of New World monkeys now recognised. Formerly, they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south.
