New World monkeys (except for the howler monkeys of genus Alouatta) [21] also typically lack the trichromatic vision of Old World monkeys. [22] Colour vision in New World primates relies on a single gene on the X-chromosome to produce pigments that absorb medium and long wavelength light, which contrasts with short wavelength light.
The capuchin monkeys (/ ˈ k æ p j ʊ (t) ʃ ɪ n /) are New World monkeys of the subfamily Cebinae. They are readily identified as the "organ grinder" monkey, and have been used in many movies and television shows.

Members of this parvorder are called platyrrhines, or New World monkeys, and include marmosets, tamarins, and capuchin, squirrel, night, titi, saki, howler, spider, and woolly monkeys. Platyrrhini is one of three clades that form the suborder Haplorrhini, itself one of two suborders in the order Primates. They are ...
The Panamanian white-faced capuchin is a member of the family Cebidae, the family of New World monkeys containing capuchin monkeys and squirrel monkeys. Until the 21st century the Panamanian white-faced capuchin was considered conspecific with Cebus capucinus , the Colombian white-faced capuchin , but as a separate subspecies C. capucinus ...
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: 2.1.3.3 2.1.3.3. Females give birth to a single young after a gestation period of between four and six months, depending on species.
The black howler (Alouatta caraya) or black-and-gold howler, [2] is among the largest New World monkeys and a member of the Alouatta genus. [3] [4] The black howler is distributed in areas of South America such as Paraguay, southern Brazil, eastern Bolivia, northern Argentina, and Uruguay.
