The brown weeper capuchin (Cebus brunneus) or Venezuelan brown capuchin is a species of gracile capuchin monkey endemic to Venezuela, although some sources also consider it to occur on Trinidad.
This taxon had previously been considered to be both Cebus albifrons trinitanus and C. olivaceus, and in 1981 had been interpreted doubtfully distinct and likely conspecific with C. capucinus by some taxonomists. [2] Boubli, Mittermeier and Rylands considered the taxon to be called C. olivaceus ssp. brunneus when they wrote the IUCN Red List assessment in 2008, classifying the subspecies within the Guianan weeper capuchin. [1]
In 2012, Boubli et al., found divergences in mitochondrial DNA of C. brunneus to be significant enough to recognise it as a separate species, and also synonymized the Trinidad white-fronted capuchin (C. trinitatis) with it based on the mitochondrial genes of the single sampled specimen. [3] [4] [5] However, subsequent morphological inspection of the C. brunneus specimens used for the study found them to be distinct from the actual type specimen of C. brunneus. [6] [7] Although the American Society of Mammalogists still recognizes the Trinidad capuchins as conspecific with C. brunneus, the ITIS recognizes them as a subspecies of Humboldt's white-fronted capuchin (C. albifrons). [7] [8]
The brown weeper capuchin has brown, thick fur with a dark wedge on the forehead and lighter face, cheeks and chin. [4] Its head and body are about 42 centimetres (17 in) with a 44 cm (17 in) tail. [4]
The different species known as white-fronted capuchins are extremely difficult to tell apart, and also appear to intergrade with each other where different taxa meet, as well as other Cebus taxa recognised as distinct. C. brunneus may be conspecific with white-faced capuchins, which often cannot reliably be distinguished from it physically. [3] [9] [10]
It lives in various types of forest in the Cordillera de la Costa in northern Venezuela, in dry semi-deciduous forests and gallery forests in the Western Venezuelan Llanos, as well as in Trinidad (under the assumption that the Trinidad white-fronted capuchin is synonymous). [4]
Trinidad white-fronted capuchins have been observed using leaves as cups to drink water from tree cavities. The leaves used were modified before by changing the shape of the leaf. The leaves are discarded after one use, meaning that a different leaf is used for repeat visits. These observations suggest that, like the common chimpanzee, wild capuchins demonstrate tool manufacture and use in foraging-related contexts. [11]
The Cebidae are one of the five families of New World monkeys now recognised. Extant members are the capuchin and squirrel monkeys. These species are found throughout tropical and subtropical South and Central America.
The tufted capuchin, also known as brown capuchin, black-capped capuchin, or pin monkey is a New World primate from South America and the Caribbean islands of Trinidad and Margarita. As traditionally defined, it is one of the most widespread primates in the Neotropics, but it has recently been recommended considering the black-striped, black and golden-bellied capuchins as separate species in a new genus, thereby effectively limiting the tufted capuchin to the Amazon basin and nearby regions. However, the large-headed capuchin, previously defined as a distinct species, has been reclassified as a subspecies of the tufted capuchin, expanding its range east to Peru & Ecuador and south to Bolivia.
White-fronted capuchin can refer to any of a number of species of gracile capuchin monkey which used to be considered as the single species Cebus albifrons. White-fronted capuchins are found in seven different countries in South America: Bolivia, Brazil, Colombia, Venezuela, Ecuador, Peru, and Trinidad and Tobago.
The Kaapori capuchin, also known as the Ka'apor capuchin, is a species of frugivorous, gracile capuchin endemic to the Brazilian Amazon. Their geographical home range is relatively small and is within the most densely populated region of the Amazon. With the strong human presence nearby,C. kaapori has had to deal with very large amounts of disturbances to their habitat and is one of the most endangered of the neotropical primates.
The wedge-capped capuchin or Guianan weeper capuchin is a capuchin monkey from South America. It is found in northern Brazil, Guyana and Venezuela. Cebus olivaceus is known to dwell in tall, primary forest and travel over long distances during the day.
The large-headed capuchin is a subspecies of the tufted capuchin monkey from South America. It is found in Bolivia, Brazil, Colombia, Ecuador and Peru. It was formerly thought to be its own species, but studies have found it to be a subspecies of the tufted capuchin.
The Ecuadorian capuchin, or Ecuadorian white-fronted capuchin is a species of gracile capuchin monkey of the family Cebidae. It was formerly classified as a subspecies of the white-fronted capuchin . Mittermeier and Rylands elevated it to a separate species in 2013. The primary physical distinction between C. albifrons and C. aequatorialis is their coloration. Due to low density and distribution researchers have not been able to make a confident molecular genetic assessment of the C. aequatorialis population, but assign it species status based on geographical isolation, morphological characteristics, and the phylogenetic species concept. The location range of the Ecuadorian Capuchin is from Western lowland Ecuador to North West Peru. The conservation status of the Ecuadorian Capuchin was originally near threatened but was revised in 2008 by the IUCN to critically endangered due to the population's rapid decline. Anthropogenic factors such as habitat fragmentation from rapid deforestation, creation of agricultural lands, and persecution from farmers are to blame for the species' critically endangered status.
Gracile capuchin monkeys are capuchin monkeys in the genus Cebus. At one time all capuchin monkeys were included within the genus Cebus. In 2011, Jessica Lynch Alfaro et al. proposed splitting the genus between the robust capuchin monkeys, such as the tufted capuchin, and the gracile capuchins. The gracile capuchins retain the genus name Cebus, while the robust species have been transferred to Sapajus.
White-faced capuchin, or white headed capuchin, can refer to either of two species of gracile capuchin monkey:
The Colombian white-faced capuchin, also known as the Colombian white-headed capuchin or Colombian white-throated capuchin, is a medium-sized New World monkey of the family Cebidae, subfamily Cebinae. It is native to the extreme eastern portion of Panama and the extreme north-western portion of South America in western Colombia and northwestern Ecuador.
Humboldt's white-fronted capuchin is a species of gracile capuchin monkey. It is found in Colombia, Venezuela, Brazil, and potentially the island of Trinidad.
The Río Cesar white-fronted capuchin is a species of gracile capuchin monkey from the Río Cesar Valley in northern Colombia. It had previously been considered a subspecies of the white-fronted capuchin. Genetic analysis by Jean Boubli in 2012 revealed that the Río Cesar white-fronted capuchin is actually more closely related to the Colombian white-faced capuchin than it is to C. albifrons. Some authors regard it to be a subspecies of the varied white-fronted capuchin.
The Trinidad white-fronted capuchin is a subspecies or species of gracile capuchin monkey. It is found on the island of Trinidad.
The varied white-fronted capuchin is a species of gracile capuchin monkey from Colombia. It had been classified as a subspecies of the white-fronted capuchin Genetic analysis by Jean Boubli in 2012 revealed it to be a separate species. Some authors regard the Río Cesar white-fronted capuchin to be a subspecies of the varied white-fronted capuchin.
The Santa Marta white-fronted capuchin is a species of gracile capuchin monkey from Colombia. It was formerly considered a subspecies of the Cebus albifrons or a synonym of the Colombian white-faced capuchin, but Mittermeier and Rylands elevated it to a species in 2013, following previous work by Rylands, Hershkovitz, Cooper and Hernandez-Camacho. The IUCN follows this taxonomy.
The Sierra de Perijá white-fronted capuchin is a species of gracile capuchin monkey from Colombia and Venezuela. It had formerly been regarded as a subspecies of the Humboldt's white-fronted capuchin but was reclassified by Mittermeier and Rylands as a separate species in 2013, based on genetic studies by Jean Boubli.
The Marañón white-fronted capuchin also or known as Peruvian white-fronted capuchin or Andean white-fronted capuchin is a species of gracile capuchin monkey from the upper Amazon Basin. It had been regarded as synonymous with the shock-headed capuchin, which was then considered a subspecies of Humboldt's white-fronted capuchin, but it was classified as a separate species by Mittermeier and Rylands based on genetic studies by Boubli.
The shock-headed capuchin is a species of gracile capuchin monkey from Bolivia and Peru. It was previously classified as a subspecies of the Humboldt's white-fronted capuchin, but in 2013 Mittermeier and Rylands elevated it to a separate species, following genetic studies by Boubli et al. in 2012 and Lynch Alfaro et al. in 2010.
Spix's white-fronted capuchin is a species of gracile capuchin monkey. It had previously been classified as a subspecies of the Humboldt's white-fronted capuchin. Following genetic studies by Boubli, et al, Mittermeier and Ryland elevated it to a full species.
The chestnut capuchin or chestnut weeper capuchin is a species of capuchin monkey from northeastern Brazil, southern Guyana, Suriname, and French Guiana.
