|Scientific Name:||Mico mauesi|
|Species Authority:||(R.A. Mittermeier, Schwarz & Ayres, 1992)|
|Taxonomic Notes:||Formerly in the genus Callithrix (see Rylands et al. 2000, 2008). Groves (2001, 2005) lists this species as Callithrix (Mico) marcai.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Rylands, A.B., Silva Jr, J.S. & Mittermeier, R.A.|
|Reviewer(s):||Mittermeier, R.A., Rylands, A.B. (Primate Red List Authority) & Hoffmann, M. (Global Mammal Assessment Team)|
Listed as Least Concern as the range of this species is remote and not particularly small, the species is adaptable, and there are no major threats resulting in a significant population decline at present.
|Range Description:||Central Amazon, south of the Rio Amazonas. In the original description, the Maués Marmoset was known only from the immediate vicinity of the type locality, but local people informed that it occurred along the Rio Maués to the south of the type locality and to the west as far as the Paraná Urariá and Rio Abacaxis. Silva Jr. and Noronha (1995) reported a further locality: Santa Maria, on the right of the lower Rio Abacaxis, municipality of Nova Olinda do Norte, state of Amazonas (3º54'S, 58º46'W). They also obtained reports of M. mauesi occurring in the vicinity of the town of Abacaxis, right bank of the Rio Abacaxis (3º55'S, 58º45'W) a few kilometers downriver from Santa Maria. It was reported not to occur at São João on the left bank of the Rio Marimari, near its confluence with the Rio Abacaxis (3º57'S, 58º48'W), nor at two other localities on the west bank of the Rio Abacaxis. Silva Jr. and Noronha (1995) reported the occurrence of a bare-eared marmoset on the west bank of the Rio Abacaxis, which they later described (1998) as Callithrix saterei.
A recent survey has increased further still the range of M. mauesi, at the expense of M. humeralifer.

|Habitat and Ecology:||
Inhabits dense tropical rain forest. Silva Jr. and Noronha (1995) observed M. mauesi in a secondary forest near a guaraná plantation.
Marmosets and tamarins are distinguished from the other monkeys of the New World by their small size, modified claws rather than nails on all digits except the big toe, the presence of two as opposed to three molar teeth in either side of each jaw, and by the occurrence of twin births. They eat fruits, flowers, nectar, plant exudates (gums, saps, latex) and animal prey (including frogs, snails, lizards, spiders and insects). Marmosets have morphological and behavioural adaptations for gouging trees trunks, branches and vines of certain species to stimulate the flow of gum, which they eat, and in some species form a notable component of the diet (Coimbra-Filho and Mittermeier 1976; Rylands 1984). They live in extended family groups of between four and 15 individuals. Generally, only one female per group breeds during a particular breeding season. The groups defend home ranges 10-40 ha, the size depending on availability and distribution of foods and second-growth patches.
Adults weigh 315 to 405 g (n=4), H&B 19.8-22.6 cm, T 34.1-37.6 cm (n=7) (Mittermeier et al. 1992; Ferrari 2008) .
No ecological-behavioural field studies have been carried out on this species.
|Major Threat(s):||There is no evidence of any current major threats to this species. They are not hunted, but may possibly be seen as pets.|
|Conservation Actions:||Not recorded from any protected areas. It is listed on Appendix II of CITES (as Callithrix mauesi).|
