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 genera Mico and Callibella were formerly considered a subgenus of the genus Callithrix. [2] [3] Callithrix differs from Mico in dental morphology and geographic distribution; Callithrix species are distributed near the Atlantic coast of Brazil, while Mico species are distributed further inland. [4] Callithrix differs from Callibella in these features, as well as in size, with Callithrix species being significantly larger. [4] Callithrix species differ from the tamarins of the genus Saguinus in that Callithrix has enlarged mandibular incisor teeth the same size as the canine teeth, which are used for gouging holes in trees to extract exudates. [5]
Some authorities, including Rosenberger (1981), believe that the pygmy marmoset, genus Cebuella , should be included within Callithrix on the basis of genetic studies, although Cebuella is significantly smaller than Callithrix. [2] [4]
In general, Callithrix and Mico species tend to form larger groups and live within smaller home ranges, thus live in higher population densities, than other callitrichids, but these statistics can vary dramatically among various Callithrix species. C. jacchus and C. pencillata typically have home territories less than 10 hectares, while other Callithrix species tend to have larger home territories. [4]

Exudates, such as gum and sap, fruit, nectar, and fungi make up the bulk of Callthrix species' diet, but they also eat animal prey such as arthropods, young birds, and small lizards and frogs. They are specialized for exploiting exudates by their elongated, chisel-like lower incisors and a wide jaw gape that allows them to gouge bark of trees that produce gums. Their intestines also have an enlarged, complex cecum that allows them to digest gums more efficiently than most other animals. The ability of Callithrix species to feed on exudates allows them to survive in areas where fruit is highly seasonal or not readily available. Some species, such as C. jacchus and C. pencillata, have been known to inhabit city parks, backyards, and coconut plantations. [4]
Callithrix females generally give birth to two, and sometimes more infants at a time. They can ovulate and conceive within 2-4 weeks after giving birth, and ovulation is not inhibited by lactation. Polygyny is known to occur in several Callithrix species. Infanticide is also known to occur, at least within C. jacchus, in which the dominant female kills the offspring of a subordinate female. Females generally reach sexual maturity between 12 and 17 months, and males between 15 and 25 months. [4]
The Callitrichidae 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.
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.
Geoffroy's tamarin, also known as the Panamanian, red-crested or rufous-naped tamarin, is a tamarin, a type of small monkey, found in Panama and Colombia. It is predominantly black and white, with a reddish nape. Diurnal, Geoffroy's tamarin spends most of its time in trees, but does come down to the ground occasionally. It lives in groups that most often number between three and five individuals, and generally include one or more adults of each sex. It eats a variety of foods, including insects, plant exudates, fruits and other plant parts. Insects and fruits account for the majority of its diet, but exudates are also important. But since its teeth are not adapted for gouging trees to get to the sap, it can only eat exudates when they are easily available.
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 silvery marmoset is a New World monkey that lives in the eastern Amazon Rainforest in Brazil.
The black-tailed marmoset is a species of New World monkey from central South America, where it ranges from the south-central Amazon in Brazil, south through the Pantanal and eastern Bolivia, to the Chaco in far northern Paraguay. It is the southernmost member of the genus Mico and the only species where most of its range is outside the Amazon.
The buffy-tufted marmoset, also known as the buffy tufted-ear marmoset or white-eared marmoset, is a New World monkey that lives in the forests on the Atlantic coast of southeast Brazil. Of all the marmosets, it has the southernmost range.
The common marmoset, also called white-tufted marmoset or white-tufted-ear marmoset, is a New World monkey. It originally lived on the northeastern coast of Brazil, in the states of Piauí, Paraíba, Ceará, Rio Grande do Norte, Pernambuco, Alagoas, and Bahia. Through release of captive individuals, it has expanded its range since the 1920s to Southeast Brazil, where it became an invasive species, raising concerns about genetic pollution of similar species, such as the buffy-tufted marmoset, and predation upon bird nestlings and eggs.
The black-tufted marmoset is a species of New World monkey that lives primarily in the Neotropical gallery forests of the Brazilian Central Plateau. It ranges from Bahia to Paraná, and as far inland as Goiás, between 14°S and 25°S, and can commonly be seen in the Rio de Janeiro city where it was introduced. This marmoset typically resides in rainforests, living an arboreal life high in the trees, below the canopy. They are only rarely spotted near the ground.
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 buffy-headed marmoset is a rare species of marmoset endemic to the rainforests of south-eastern Brazil. It occurs in southern Espírito Santo and possibly northern Rio de Janeiro and its distribution extends into Minas Gerais.
The Santarem marmoset, also known as the black and white tassel-ear marmoset, is a marmoset endemic to the Brazilian states of Amazonas and Pará.
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 Rio Acarí marmoset is a marmoset species endemic to Brazil. It was first described in 2000.
The Marca's marmoset is a species of marmoset that is endemic to the Amazon, in the Aripuanã-Manicoré interfluvium in Brazil. Its body is light grey, with orange legs, a black tail, a pinkish face, and naked ears. It is about 9 inches (23 cm) long, excluding the tail, and it has a 15-inch (38 cm) long tail. It weighs about 12 ounces (340 g).
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.
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.
A gummivore is an omnivorous animal whose diet consists primarily of the gums and saps of trees and bugs for protein. Notable gummivores include arboreal, terrestrial primates like certain marmosets and lemurs. These animals that live off of the injuries of trees live from about 8m off of the ground up to the canopies. The feeding habit of gummivores is gummivory.
The western pygmy marmoset is a marmoset species, a very small New World monkey found in the northwestern Amazon rainforest in Brazil, Colombia, Ecuador, and Peru. It was formerly regarded as conspecific with the similar eastern pygmy marmoset, which has whitish underparts. Although the western pygmy marmoset occurs further west than the eastern pygmy marmoset, the primary separators of their ranges are the Amazon River and Marañón River, with the western occurring to the north of them and the eastern to the south.
The eastern pygmy marmoset is a marmoset species, a very small New World monkey, found in the southwestern Amazon Rainforest in Bolivia, Brazil, Ecuador, and Peru. It was formerly regarded as conspecific with the similar western pygmy marmoset, but the eastern pygmy marmoset has whitish colored underparts. Although the eastern pygmy marmoset occurs further east than the western pygmy marmoset, the primary separators of their ranges are the Amazon River and Maranon River, with the western occurring to the north of them and the eastern to the south. The species has recently been confirmed by DNA testing to exist in Ecuador, hundreds of kilometers north of the Maranon River.
