Pitheciidae
Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south.They have medium to long fur, in a wide range of colors, often with contrasting patches, especially on the face.They are diurnal and arboreal animals, found in tropical forests from low-lying swamp to mountain slopes.The titis and Pithecia sakis, by contrast, are monogamous and live in much smaller family groups.Silvestro etal 2017 showed the relationship among the extinct and extant pitheciid genera:[5] Homunculus Carlocebus Cheracebus Miocallicebus Callicebus Plecturocebus Antillothrix Xenothrix Insulacebus Mazzonicebus Nuciruptor Soriacebus Pithecia Cebupithecia Proteropithecia Chiropotes Cacajao
