The Colombian woolly monkey (Lagothrix lagothricha lugens) is a critically endangered subspecies of the common woolly monkey from Colombia.
It was initially thought to be a subspecies of the common woolly monkey (L. lagothricha), but was later reclassified as its own species. However, a 2014 phylogenetic study found it to in fact be a subspecies of L. lagothricha; the results of this study have been followed by the American Society of Mammalogists and the IUCN Red List.

Among all ateline primates, Colombian woolly monkeys exhibit the most sexual dimorphism in body size. Males are about forty-five percent heavier than their female counterparts. [6] However, the cause of this dimorphism remains an enigma as there are no apparent female choice in favor of larger males. In fact, mating amongst Colombian woolly monkeys is promiscuous in that all adult and subadult males in a group mate with each female in estrous, and male-male rivalries in the context of mating are very rare.

The common patas monkey, also known as the wadi monkey or hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa.
The woolly monkeys are the genus Lagothrix of New World monkeys, usually placed in the family Atelidae.
The gray-bellied night monkey, also called the grey-legged douroucouli or lemurine owl monkey, is a small New World monkey of the family Aotidae. Native to tropical and subtropical forests of South America, the gray-bellied night monkey faces a significant threat from hunting, harvesting for use in pharmaceutical research and habitat destruction.
Squirrel monkeys are New World monkeys of the genus Saimiri. Saimiri is the only genus in the subfamily Saimirinae. The name of the genus is of Tupi origin and was also used as an English name by early researchers.
The Nilgiri langur is a langur. This primate has glossy black fur on its body and golden brown fur on its head. It is similar in size and long-tailed like the gray langurs. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten monkeys. Its diet consists of fruits, shoots and leaves. The species is classified as vulnerable due to habitat destruction and poaching for its fur and flesh, the latter believed to have aphrodisiac properties.
The Colombian red howler or Venezuelan red howler is a South American species of howler monkey, a type of New World monkey, found in the western Amazon Basin in Venezuela, Colombia, Ecuador, Peru and Brazil. The population in the Santa Cruz Department in Bolivia was split off as a separate species, the Bolivian red howler, in 1986, and more recently, splitting off the population in northeastern South America and Trinidad as the Guyanan red howler has occurred. All howler monkeys belong to the family Atelidae and the infraorder Platyrrhini.
The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey is a woolly monkey from Colombia, Ecuador, Peru, Bolivia, Brazil, and Venezuela. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active.
The collared titi is a species of titi, a type of New World monkey. It is endemic to northern Brazil.
The gray woolly monkey or Geoffroy's woolly monkey is a subspecies of the common woolly monkey from South America. It is found in Bolivia, Brazil and Peru. L. l. cana gets its common name, gray woolly monkey, from its thick gray coat. Its hands, feet, face and the inside of the arms are dark in color. The gray woolly monkey has been considered endangered by IUCN since 2008. The subspecies is listed as endangered because it suffered a 50% decrease in population over the past 45 years due to deforestation and hunting.
The silvery woolly monkey, also known as Poeppig's woolly monkey or the red woolly monkey, is a subspecies of the common woolly monkey from South America. Named after the German zoologist Eduard Friedrich Poeppig, it is found in Brazil, Ecuador and Peru.
Geoffroy's spider monkey, also known as the black-handed spider monkey or the Central American spider monkey is a species of spider monkey, a type of New World monkey, from Central America, parts of Mexico and possibly a small portion of Colombia. There are at least five subspecies. Some primatologists classify the black-headed spider monkey, found in Panama, Colombia, and Ecuador as the same species as Geoffroy's spider monkey.
The yellow-tailed woolly monkey is a New World monkey endemic to Peru. It is a rare primate species found only in the Peruvian Andes, in the departments of Amazonas and San Martin, as well as bordering areas of La Libertad, Huánuco, and Loreto.
The northern muriqui is one of two species of muriqui. They are also known as woolly spider monkey because they exhibit the woollen pelt of woolly monkeys and the long prehensile tail of spider monkeys. Muriquis are the largest extant New World monkeys. They can reach 4.3 feet or 1.3 metres long and weight up to 7 to 10 kilograms. The northern muriqui is a critically endangered species that is unusual among primates in that they display egaltarian tendencies in their social relationships. This species is endemic to the Atlantic Forest region of Brazilian states of Rio de Janeiro, Espírito Santo, Minas Gerais and Bahia. Their diets, travel patterns and reproductive cycles are seasonally determined. The size of each group can fluctuate as females will move between groups of monkeys.

Gracile capuchin monkeys are capuchin monkeys in the genus Cebus. At one time all capuchin monkeys were included within the genus Cebus. In 2011, Jessica Lynch Alfaro et al. proposed splitting the genus between the robust capuchin monkeys, such as the tufted capuchin, and the gracile capuchins. The gracile capuchins retain the genus name Cebus, while the robust species have been transferred to Sapajus.
Humboldt's white-fronted capuchin is a species of gracile capuchin monkey. It is found in Colombia, Venezuela, Brazil, and potentially the island of Trinidad.
Humboldt's squirrel monkey is a species of squirrel monkey from Brazil, Colombia, Ecuador, Peru and Venezuela. It had previously been considered a subspecies of the common squirrel monkey, S. scuireus, but was elevated to full species status based on a genetic study by Carretero-Pinzón in 2009. A genetic study by Jessica Lynch Alfaro, et al indicated that the Ecuadorian squirrel monkey may be synonymous with Saimiri cassiquiarensis. As of 2018, the Ecuadorian squirrel monkey is generally regarded as a subspecies of Humboldt's squirrel monkey, S. cassiquiarensis macrodon.
The Guianan squirrel monkey is a species of squirrel monkey from Guiana, Venezuela and Brazil. S. sciureus formerly applied to Humboldt's squirrel monkey and Collins' squirrel monkey, but genetic research in 2009 and 2015 revealed that these are distinct species.
The Ecuadorian squirrel monkey is a type of squirrel monkey. It had been considered a subspecies of the Guianan squirrel monkey, Saimiri sciureus, but was elevated to a full species, S. macrodon, based on a 2009 study by Carretero-Pinzón, et al. Based on subsequent genetic research by Jessica Lynch Alfaro, et al it was again reclassified as a subspecies of Humboldt's squirrel monkey.
