Бурая тити: Эндемик Бразилии.

Species of New World monkey

The brown titi monkey (Plecturocebus brunneus) is a species of titi monkey, a type of New World monkey, from South America. It is endemic to Brazil. It was originally described as Callicebus brunneus in 1842 and transferred to the newly erected genus Plecturocebus in 2016.

Plecturocebus are within a subfamily of titi called Callicebinae. Other genera included within this subfamily are the Cheracebus, Callicebus, and Plecturocebus; which are all still currently extant. The Xenothrix, Antillothrix, Paralouatta, Carlocebus, Lagonimico, and Tremacebus genera of Callicebinae are extinct. The Urubamba brown titi (P. urubambensis) of Peru was formerly thought to be a Peruvian population of P. brunneus, but a 2015 study found it to be a distinct, undescribed species more closely related to the white eared titi (P. donacophilus), and described it as such. The Brown Titi was classified as its own genus in 2016. Due to the previous classification before independent definition, P. brunneus is now thought to be endemic to Brazil.

The Brown Titi do not differ too dramatically from their relatives, however, they are notably unique in their combination of morphological features. Individuals of this species possess a grey agouti colouration on the crown of the head and dorsal parts, a bright red brown venter, an almost completely black tail with a pale tip, and light yellow colouration of the hair on the cheeks with bright red brown hair on the sides of the face. The different species of titi are identifyable by their combination of these morphological traits. This classification is what contributed to P. Brunneus earning the status as its own individual species. Their diet reflects that of other species of titi. They have a diet consisting of mainly fruits as well as flowers, leaves, insects and small vertebrates. They are endemic to the Caatinga in Brazil. Titis are territorial and defend their territory by shouting or hollering at the predator or intruder.
