New World Monkeys - Parvorder Platyrrhini
While not as numerous as the old world monkeys, there are still 60 species found in south America. These are split into 5 families which we will deal with one by one.
- Family Callitrichidae (Also known as Arctopitheci or Hapalidae – this family has been at times considered a subsfamily of Cebidae): marmosets and tamarins (and Lion Tamarins). this family consists of 7 living genus.
So firstly Tamarins. There are 2 genus
Genus Saguinus, subgenus Saguinus
Second Subgenus Tamarinus
Second Genus Leontocebus
Next we have Genus Leontopithecus which is the genus of Lion Tamarins
Finally, we have 25 marmosets across 4 genusÂ
Next the Cebidae family – these are made up of capuchin and squirrel monkeys.
First Subfamily Cebinae, which contains 2 genus
The genus Cebus the is the gracile capuchin monkeys
The other genus is Sapajus which are the robust capuchin monkeys
The other Subfamily Saimiriinae is made up of the squirrel monkeys. This has only one genus: Saimiri
Genus Saimiri - Squirrel monkeys
The third is family Aotidae which consists of the night (or owl) monkeysÂ
Firstly, Actus Lemurinus (grey necked) Group
and secondly, Genus Aotus azarae (red necked) Group
The fourth is family Atelidae. This contains 2 subfamilies the first of which is Subfamily Alouattinae.
This contains just Genus Alouatta which is howler monkeys. This genus is split into 3 groups – we will cover the first 2 groups in one gallery (name of group will be included with name of species
The third group of this genus is Alouatta seniculus group, which has more species.
The other Subfamily Atelinae contains both spider and wooly monkeys.
This has 3 genus
Firstly, Genus Ateles, spider monkeys
The second genus is Genus Brachyteles, the muriquis woolly spider monkeysÂ
The third genus is Genus Lagothrix containing the woolly monkeys
The last south american subfamily of monkeys is Pitheciidae.
This contains 2 sub families which we will deal with in turn
Subfamily Callicebinae, titis Which contains 3 genusÂ
The first genus is Genus Callicebus
 The second Genus is Cheracebus
and the third Genus is Plecturocebus (a titi monkey genus)
