The marmosets, also known as zaris or sagoin, are 22 New World monkey species of the genera Callithrix, Cebuella, Callibella, and Mico. All four genera are part of the biological family Callitrichidae. The term "marmoset" is also used in reference to Goeldi's marmoset, Callimico goeldii, which is closely related.
The four species of lion tamarins or maned marmosets make up the genus Leontopithecus. They are small New World monkeys named for the mane surrounding their face, similar to the mane of a lion.
The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus Saguinus. They are the first offshoot in the Callitrichidae tree, and therefore are the sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets.
The Roosmalens' dwarf marmoset, also known as the black-crowned dwarf marmoset, is a small New World monkey native to the Amazon Rainforest, on the east bank of the lower Madeira River, and the west bank of the Aripuanã River, in Brazil. It has the smallest distribution of any primate in Amazonia. This marmoset has several unique attributes, which has resulted in it sometimes being placed in the monotypic genus Callibella. However, genetic analysis has subsequently resulted in its being classified within the genus Mico.
The black-mantled tamarin, Leontocebus nigricollis, is a species of saddle-back tamarin from the northwestern Amazon in far western Brazil, southeastern Colombia, north-eastern Peru and eastern Ecuador.
The black tamarin or western black-handed tamarin, is a species of tamarin endemic to Brazil.
The brown-mantled tamarin, also known as Spix's saddle-back tamarin, is a species of saddle-back tamarin. This New World monkey is found in the Southern American countries of Bolivia, Brazil and Peru. This omnivorous member of the Callitrichidae family is usually found in smaller groups ranging between 4 and 15 individuals. This species communicates vocally and largely rely their olfactory system. The brown-mantled tamarin is considered as a species of Least Concern by the International Union for Conservation of Nature, despite a decreasing population and being threatened by poaching, habitat loss and capture for the illegal pet trade.
The golden-mantled tamarin is a tamarin species from South America. It is found in Ecuador and Peru, specifically in the upper Amazon (lowland), east of the Andes in Ecuador, and Northeast Peru; between the Rio Curaray and Rio Napo in Peru.
Graells's tamarin, Leontocebus nigricollis graellsi, is a subspecies of the black-mantled tamarin from the northwestern Amazon in southeastern Colombia, eastern Ecuador and northeastern Peru. It differs from other black-mantled tamarins in having a dull olive-brown lower back, rump and thighs. However, molecular genetic analysis does not support treating Graell's tamarin as a separate species from the black-mantled tamarin.
The white-mantled tamarin, Leontocebus weddelli melanoleucus, is a subspecies of Weddell's saddle-back tamarin, a tamarin monkey from South America. It is found in Brazil, between Rio Jurua and Rio Tarauacá.
Mico is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus was formerly considered a subgenus of the genus Callithrix.
Callithrix is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus contains the Atlantic Forest marmosets. The name Callithrix is derived from the Greek words kallos, meaning beautiful, and thrix, meaning hair.
The saddle-back tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus or subgenus Leontocebus. They were split from the tamarin genus Saguinus based on genetic data and on the fact that saddle-back tamarins are sympatric with members of Saguinus to a greater extent than would be expected from two members of the same genus. However, this argument can be circular, as several other mammals show sympatry among congeneric species, such as armadillos, spotted cats, and fruit-eating bats. Some authors still consider Leontocebus to be a subgenus of Saguinus.
Cruz Lima's saddle-back tamarin is a species of saddle-back tamarin, a type of small monkey from South America. Cruz Lima's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis. It lives in Brazil in the area near the Inauini River. Its fur is mostly reddish orange, with a black tail and white eyebrows. The IUCN rates it as least concern from a conservation standpoint.
Geoffroy's saddle-back tamarin is a species of saddle-back tamarin, a type of small monkey from South America. Geoffroy's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis. It lives in Loreto, Peru.
Weddell's saddle-back tamarin is a species of saddle-back tamarin, a type of small monkey from South America. Weddell's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis. It lives in Brazil, Bolivia and Peru, with the type locality being in Bolivia.
Lagonimico is an extinct genus of New World monkeys from the Middle Miocene. Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is L. conclucatus.
Lesson's saddle-back tamarin is a species of saddle-back tamarin, a type of small monkey from South America. Lesson's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis. Genetic analysis showed it to be more closely related to the black-mantled tamarin than to the brown-mantled tamarin. Its type locality is in Colombia, in Plaines de Mocoa, Putumayo, between the Rio Putumayo and Rio Caqueta. It also lives in Brazil.
