The brown Urubamba spring monkey ( Plecturocebus urubambensis , Syn . : Callicebus urubambensis ) is a South American primate species that occurs in Peru. The exact limits of the distribution area are not known. It begins in the northwest in the small part of the Ucayali region south of the Río Urubamba , then extends over the extreme north of the Cusco region and then extends over the Manú National Park to the upper reaches of the Río Madre de Dios in the southeast. The species was only described in mid-2015 and named after the Río Urubamba, which flows through the range. Originally the monkeys in this area were assigned to the brown jumper monkey ( Plecturocebus brunneus ). In Peru the monkey species is called “mono tocón”, the authors of the first description suggest Urubamba brown titi monkey as an English common name for the species.
features
The holotype of the Urubamba brown monkey has a head-trunk length of 30 cm and a 40 cm long tail. It has a dark brown fur made up of aguti-colored hair. Hands and the insides of the arms are black. The outsides of the arms are also black, but the black hair is mixed in with a small amount of agouti-colored hair up to the elbows. The abdomen and legs are lighter than the back and are brown-aguti in color. The feet are black, the knees darker than the rest of the legs. The face is surrounded by brown-agouti-colored hair that has black tips and is directed forward. The face wreath appears black overall. The bare skin of the face is black, black hair is on the cheeks, white around the mouth and nose. The pupils are black, the iris light brown. The ears are covered with long black hair, the chin is brown-aguti-colored. The body-hugging half of the tail is black, mixed with a small amount of brownish, aguti-colored hair, towards the end it becomes increasingly gray. The tip of the tail is white. As with all Amazonian jumper monkeys, males and females look the same. From the reddish Plecturocebus toppini , the area of distribution of which overlaps in small sections with that of Plecturocebus urubambensis , the latter can easily be distinguished by its overall darker appearance. From the brown jumper monkey, which occurs further east in the Brazilian state of Rondônia , the brown Urubamba jumper monkey differs mainly in the color of the back of the head and sides of the head, which in this species does not stand out from the back color, while the back of the head of the brown jumper monkey is yellowish and the cheeks are darker than the back.
