( Miranda Ribeiro , 1912)

The white- mantled tamarin ( Leontocebus weddelli melanoleucus , syn .: Saguinus weddelli melanoleucus ) is a primate form of the marmoset family (Callitrichidae). It was viewed in the past as a subspecies of the brown-backed tamarin , then as an independent species and is now considered a subspecies of the black- mantled tamarins ( Leontocebus weddelli ).

features

White-mantled tamarins reach a head body length of around 25 centimeters, the tail is around 38 centimeters long. Their fur is almost completely creamy white ( leucus = white). Only the hairless ears, the uncovered facial skin and the external genitals are black. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails.

distribution and habitat

White-coat tamarins are native to the western Amazon basin in South America, their range is south of the upper Rio Juruá in the far west of Brazil and perhaps in the neighboring regions of Peru . Their habitat are tropical rainforests .

Way of life

Little is known about the way of life of the white-coat tamarins, presumably it largely corresponds to that of other tamarinas from the genus Leontocebus . As a result, they are diurnal tree dwellers who live together in small groups. They are omnivores that eat insects, fruits, nectar and other things. As with all tamarins , only the dominant female is likely to reproduce and usually give birth to twins.

Systematics

The white-coat tamarin was described by the Brazilian zoologist Miranda Ribeiro in 1912. For a long time it was considered a subspecies of the brown-backed tamarin ( Leontocebus fuscicollis ), then as an independent species and is assigned to the black- mantled tamarin ( Leontocebus weddelli ) in more recent publications . From this it does not differ genetically at all, but was not synonymous with the nominate form due to the strongly deviating coat color , but received a status as a subspecies.

Danger

In some areas, the destruction of their habitat poses a threat to the species, but overall it is widespread and is listed by the IUCN as “ least concern” .
