The Callitrichidae (also called Arctopitheci or Hapalidae) are a family of New World monkeys, including marmosets, tamarins, and lion tamarins. At times, this group of animals has been regarded as a subfamily, called the Callitrichinae, of the family Cebidae.
This taxon was traditionally thought to be a primitive lineage, from which all the larger-bodied platyrrhines evolved. [4] However, some works argue that callitrichids are actually a dwarfed lineage. [5] [6]
Ancestral stem-callitrichids likely were "normal-sized" ceboids that were dwarfed through evolutionary time. This may exemplify a rare example of insular dwarfing in a mainland context, with the "islands" being formed by biogeographic barriers during arid climatic periods when forest distribution became patchy, and/or by the extensive river networks in the Amazon Basin. [5]
All callitrichids are arboreal. They are the smallest of the simian primates. They eat insects, fruit, and the sap or gum from trees; occasionally, they take small vertebrates. The marmosets rely quite heavily on tree exudates, with some species (e.g. Callithrix jacchus and Cebuella pygmaea ) considered obligate exudativores. [7]
Callitrichids typically live in small, territorial groups of about five or six animals. Their social organization is unique among primates, and is called a "cooperative polyandrous group". This communal breeding system involves groups of multiple males and females, but only one female is reproductively active. Females mate with more than one male and each shares the responsibility of carrying the offspring. [8]
They are the only primate group that regularly produces twins, which constitute over 80% of births in species that have been studied. Unlike other male primates, male callitrichids generally provide as much parental care as females. Parental duties may include carrying, protecting, feeding, comforting, and even engaging in play behavior with offspring. In some cases, such as in the cotton-top tamarin (Saguinus oedipus), males, particularly those that are paternal, even show a greater involvement in caregiving than females. [9] The typical social structure seems to constitute a breeding group, with several of their previous offspring living in the group and providing significant help in rearing the young.
Taxa included in the Callitrichidae are: [10] [11] [12] [13]
The marmosets, also known as zaris or sagoin, are twenty-two 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.
Pygmy marmosets are two species of small New World monkeys in the genus Cebuella. They are native to rainforests of the western Amazon Basin in South America. These primates are notable for being the smallest monkeys in the world, at just over 100 g (3.5 oz). They are generally found in evergreen and river-edge forests and are gum-feeding specialists, or gummivores.
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 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 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.
Rondon's marmoset, also known as the Rondônia marmoset, is a small species of monkey from the family Callitrichidae found in the south-western Amazon in Brazil. It is endemic to the state of Rondônia, and its range bordered by the Rio Mamoré, Rio Madeira, Rio Ji-Paraná, Serra dos Pacaás Novos and possibly Bolivia. It was only described in 2010, and its name refers to the famous Amazonian explorer Cândido Rondon. Prior to its description, it was included in Emilia's marmoset.
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 Lagonimico 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.
