Schneider's marmoset

Schneider's marmoset (Mico schneideri) is a marmoset of the family Callitrichidae, endemic to Brazil, where it lives in primary and secondary terra firma rainforest and the transition zone to the Cerrado in Mato Grosso state, between the Juruena and Teles Pires rivers. It was long treated as a population of Emilia's marmoset, but a morphological and phylogenetic study in 2021 showed it to be distinct, and it was named in honour of the Brazilian biologist Horácio Schneider. Its back and rump are lead-coloured, the underparts cream-silver, the neck and crown grey, the hands light orange, the feet orange and the tail black. It lives in the arc of deforestation, a 2,500 kilometre stretch of the Amazon under the greatest pressure from agricultural clearing. Its closest relatives are the black-tailed marmoset and Marca's marmoset.
