The brown-bellied spring monkey ( Plecturocebus caligatus , syn .: Callicebus caligatus ) is a primate species from the subfamily of the spring monkeys within the family of the sakia monkeys (Pitheciidae). It is closely related to the red jumper monkey and is sometimes combined into one species with it.

features

Brown-bellied jumper monkeys, like all jumper monkeys, are relatively small primates with thick fur . This is dark brown on the back and on the outside of the limbs, the chest and stomach are orange-brown in color. The bushy tail is longer than the body, it is dark at the base of the tail and becomes lighter towards the tip. As with all jumping monkeys, it cannot be used as a prehensile tail. The head is small and rounded. There is a noticeable black stripe on the forehead, the long hair on the cheeks and throat are orange-brown.

distribution and habitat

Brown-bellied juggler monkeys inhabit a relatively small area in the Amazon basin in Brazil . It is bounded in the north by the Amazon , in the west by the Rio Purus and in the south and east by the Rio Madeira . Their habitat are tropical rainforests .

Way of life

Little is known about the way of life of the brewery ape monkeys. They are diurnal tree dwellers who move on all fours or jumping. Like all jumping monkeys, they are likely to live in monogamous family groups in which the partners often stay together for life. They live in fixed territories, which they point out to other animals by singing duets in the morning. Their diet consists mainly of fruits and, to a lesser extent, leaves and other parts of plants and insects.

Danger

This species lives in a sparsely populated area and is therefore not endangered according to the IUCN ( least concern ).

Systematics

The brown-bellied spring monkey is one of around 30 species from the subfamily of spring monkeys (Callicebinae). He was the 1842 German zoologist Johann Andreas Wagner under the scientific name Callicebus caligatus described and 2016 along with all other titi monkeys from the cupreus - juggernaut group of species of newly introduced species Plecturocebus assigned.

The Hershkovitz spring monkey, described in 1990 by the primatologist Philip Hershkovitz under the scientific name Callicebus dubius , differs so little in its genetics from the brown-bellied spring monkey that it can only be viewed as a geographical color morph of this species and was synonymous with this in 2016 . It occurs in the western Amazon basin from the upper Rio Purus to the Río Madre de Dios . The fur of the Hershkovitz jumper monkey is colored gray-brown on the back and on the outside of the limbs, the belly, the inside of the limbs and the forearms and legs are reddish, the fingers and toes are white. The tail is longer than the body and bushy, it is gray at the base of the tail and blackish in color at the rear and ends in a white tassel. The head is small and rounded, its upper side is colored gray like the back. A white horizontal stripe stretches along the forehead, underneath a narrow black stripe that connects the ears. The bushy cheek and throat hair are colored reddish.
