Callicebus Personatus Espírito Santo
''Callicebus'' is a genus of monkeys known as titi monkeys. Historically, titis were monogeneric, comprising only the genus ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae; ''Cheracebus'' Byrne et al., 2016 for the species of the ''torquatus'' group (Widow titis); ''Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; and ''Callicebus'' Thomas, 1903 ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group. In 2014, a previously unknown orange ''Callicebus'' was spotted in the Peruvian Amazon; it has not been determined whether this constitutes a color variant or a new species. Species There are 5 species in this genus: * Barbara Brown's titi monkey, ''Callicebus barbarabrownae'' * Coimbra Filho's titi monkey, ''Callicebus coimbrai'' * Coastal bla ...

Atlantic Titi
The Atlantic titi monkey or masked titi (''Callicebus personatus'') is a species of titi, a type of New World monkey, endemic to Brazil. Distribution and general features The Atlantic titi is part of the genus ''Callicebus'' which is composed of thirteen species and sixteen subspecies. Some more recent classifications of titis recognise many more species, and split the genus into three separate genera. The ''C. personatus'' group is retained in ''Callicebus''. Three subspecies of ''Callicebus personatus'' have been described in scientific literature: ''C.p. melanochir'', ''C.p. nigrifrons'', and ''C.p. personatus'', each of which has been treated as a full species by some authors. Atlantic titis are territorial, middle-sized, cebid monkeys; usually 1–2 kg in size. ''C. personatus'' are found primarily in the humid forests east of the Andes Mountains, specifically in the coastal, inland forests of south-eastern Brazil. The states they have been documented to dwell within in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plecturocebus
''Plecturocebus'' is one of three genera of titi monkeys. Historically, these monkeys were monogeneric, being placed in a single genus: ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was proposed in 2016 that recognises three genera within the subfamily Callicebinae; ''Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; ''Cheracebus ''Cheracebus'' is one of three genera of titi monkeys.

Primate Genera
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Coastal Black-handed Titi Monkey
The coastal black-handed titi monkey (''Callicebus melanochir'') is a species of titi, a type of New World monkey, endemic to Brazil. Description Coastal black-handed titis are relatively small primates with fluffy fur, a long, bushy tail and a small, roundish head. Like atlantic titis, they can reach a head trunk length of over 40 centimetres and a weight of up to 1.6 kilograms. Their dense fur is predominantly grey or grey-brown in colour, the head and paws are black. The long tail is the same colour as the torso, as with all jumping monkeys it cannot be used as a prehensile tail. Distribution and habitat Coastal black-handed titis are found on the Brazilian Atlantic coast, their range includes the south of Bahia and the north of Espírito Santo. Their habitat is coastal forest. Behavioral ecology Not much is known about the lifestyle of the coastal black-handed titis, but it is probably the similar to that of the atlantic titi. They are diurnal tree dwellers t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cheracebus
''Cheracebus'' is one of three genera of titi monkeys. Monkeys in this genus, particularly the type species ''Cheracebus lugens'', are sometimes referred to as widow titi monkeys. Historically, titis were monogeneric, comprising only the genus ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae; ''Cheracebus'' Byrne et al., 2016 for the species of the ''torquatus'' group (Widow titis); ''Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; and ''Callicebus'' Thomas, 1903 ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group. ''Cheracebus'' is derived from the Latin ''chera'' (from the Greek χηρα) meaning widow and ''cebus'' (from the Greek kebos) meaning long tailed monkey.

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history.

Callicebinae
The titis, or titi monkeys, are New World monkeys of the subfamily Callicebinae, which contains three extant genera: ''Cheracebus'', ''Callicebus'', and ''Plecturocebus.'' This subfamily also contains the extinct genera ''Miocallicebus, Homunculus'', and ''Carlocebus''. Titi monkeys live in South America, from Colombia, Ecuador and Peru, east through Brazil, and south to Bolivia and northern Paraguay. Description Depending on species, titis have a head and body length of , and a tail, which is longer than the head and body, of . The different titi species vary substantially in coloring, but resemble each other in most other physical ways. They have long, soft fur, and it is usually reddish, brownish, grayish or blackish, and in most species the underside is lighter or more reddish than the upperside. Some species have contrasting blackish or whitish foreheads, while all members of the genus ''Cheracebus'' have a white half-collar. The tail is always furry and is not preh ...
