Pitheciidae
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 Amazonia region of Brazil, with some being found from Colombia in the north to Bolivia in the south.
Characteristics
Pithecids are small to medium monkeys, ranging from 23 cm in head-body length, for the smaller titis, to 44-49 cm in the uakaris. 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. They are predominantly herbivorous, eating mostly fruit and seeds, although some species will also eat a small number of insects. Sakis and uakaris have a diastema between the canine and premolar teeth, but the titis, which have unusually small canines for New World monkeys, do not.[2] All species have the dental formula:
Females give birth to a single young after a gestation period of between four to six months, depending on species. The uakaris and bearded sakis are polygamous, living in groups of 8-30 individuals. Each group has multiple males, which establish a dominance hierarchy amongst themselves. The titis and Pithecia sakis, by contrast, are monogamous and live in much smaller family groups.[2]
Classification
There are 43 currently recognized extant species of pithecid monkey, grouped into two subfamilies and four genera.[1][3] Seven extinct genera known from the fossil record are placed in the subfamily Pitheciinae and extending the age of the family to the Miocene.[4]
