Colobinae
The Colobinae or leaf-eating monkeys are a subfamily of the Old World monkey family that includes 61 species in 11 genera, including the black-and-white colobus, the large-nosed proboscis monkey, and the gray langurs. Some classifications split the colobine monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera ''Colobus'', '' Piliocolobus'', and '' Procolobus'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of mtDNA confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups, while others place them firmly within the langur group.

Pig-tailed Langur
The pig-tailed langur (''Simias concolor''), monotypic in genus ''Simias'', is a large Old World monkey, endemic to several small islands off the coast of Sumatra in Indonesia. Its face is black, its fur is black-brown and it has a relatively short tail. It is a diurnal species, feeding in the rainforest canopy on leaves, and to a lesser extent, fruit and berries. Little is known of its natural history, but it is heavily hunted, its populations have been declining rapidly and the International Union for Conservation of Nature has assessed its conservation status as being " critically endangered". It has been included on a list of the World's 25 Most Endangered Primates. As an arboreal primate the pig-tailed langur spends most of its time in the canopy devoting the majority of its activity budget towards resting and feeding. The structure of groups is single-male, multi-female. Group sizes range from around 3 to 9 individuals depending on locations and hunting pressures. There are ...

Old World Monkey
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus'') and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus ''Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, surili (''Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago. The smallest Old World monkey is the talapoin, with a head and body 34–37 cm in length, and weighing between 0.7 and 1.3 kg. The largest is the male mandrill, around 70 cm in length, and weighing up to 50 kg. Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Langur
Gray langurs, also called Hanuman langurs and Hanuman monkeys, are Old World monkeys native to the Indian subcontinent constituting the genus ''Semnopithecus''. Traditionally only one species ''Semnopithecus entellus'' was recognized, but since about 2001, additional species have been recognized. The taxonomy has been in flux, but currently eight species are recognized. Gray langurs are fairly Terrestrial animal, terrestrial, inhabiting forest, open lightly wooded habitats, and urban areas on the Indian subcontinent. Most species are found at low to moderate altitudes, but the Nepal gray langur and Kashmir gray langur occur up to in the Himalayas. Characteristics These langurs are largely gray (some more yellowish), with a black face and ears. Externally, the various species mainly differ in the darkness of the hands and feet, the overall color and the presence or absence of a crest. Typically all north Indian gray langurs have their tail tips looping towards their head during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapresbytis
''Parapresbytis'' is an extinct genus of colobine monkey that lived in northeast Asia during the Mid-Late Pliocene. It is represented by single species known as ''Parapresbytis eohanuman'', whose remains have been found throughout the Transbaikal area. Taxonomy ''Parapresbytis eohanuman'' was once considered a species of ''Dolichopithecus'', but was found to be distinct. There is debate as to its exact position within Colobinae, with some researchers considering it an ancestor to certain Asian colobines such as snub-nosed monkeys, and others considering it a member of a primitive colobine radiation that includes ''Dolichopithecus'' and left no descendants. ''Parapresbytis'' seems to display a mosiac of distinct features shared with different living Asian colobine species, making its placement uncertain. Description ''Parapresbytis'' was a large monkey, with an ulnar comparable in size to a chacma baboon The chacma baboon (''Papio ursinus''), also known as the Cape baboon, is, ...

Lutung
The lutungs, langurs, or leaf monkeys are a group of Old World monkeys in the genus ''Trachypithecus'' (derived from Greek , meaning "rough" and , meaning "monkey"). Their range is much of Southeast Asia (northeast India, Vietnam, southern China, Borneo, Thailand, Java, and Bali). The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *''luCuŋ'' (which originally referred to the Formosan rock macaque); it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus ''Semnopithecus'', although some "lutungs" are now "langurs" again. Evolution Genetic analysis indicates that the ancestors of the modern species of lutung first differentiated from one another a little over 3 million years ago, during the late Pliocene. The various species alive today then diverged during the Pleistocene, presumably driven by habitat changes during the Ice Ages. The oldest fossils clearly identif ...

Proboscis Monkey
The proboscis monkey (''Nasalis larvatus'') or long-nosed monkey is an arboreal Old World monkey with an unusually large nose, a reddish-brown skin color and a long tail. It is endemic to the southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island. This species co-exists with the Bornean orangutan and monkeys such as the silvery lutung. It belongs in the monotypic genus ''Nasalis''. Taxonomy and names Proboscis monkeys belong to the subfamily Colobinae of the Old World monkeys. The two subspecies are: *''N. l. larvatus'' (Wurmb, 1787), which occupies the whole range of the species *''N. l. orientalis'' (Chasen, 1940), restricted to north-east Kalimantan However, the difference between the subspecies is small, and not all authorities recognise ''N. l. orientalis''. The species is known as ''monyet belanda'' in Malaysia or ''bekantan'' in Indonesia. Description The proboscis monkey is a large species, being one of the lar ...

Dolichopithecus
''Dolichopithecus'' is an extinct genus of Old World monkey that lived in Europe during the Late Miocene and Pliocene. Taxonomy The type species ''Dolichopithecus ruscinensis'' was first described in 1889 by Charles Depéret, based on fossil remains from the Roussillon area in France dating back to the Middle Pliocene. Numerous fossils of ''D. ruscinensis'' have been found in European Pliocene deposits from France, Spain, Bulgaria, Hungary, Romania, and Ukraine. A second species, ''D. balcanicus'', has been described from remains found in the Balkans. Some extinct colobine species from Asia have formerly been included in ''Dolichopithecus''; ''D. leptopostorbitalis'' of Japan, now placed in '' Kanagawapithecus'', and ''D. eohanuman'' from northeast Asia, now in ''Parapresbytis''. '' Paradolichopithecus arvernensis'' was also originally included under this genus, but is more related to macaques rather than colobines. ''Dolichopithecus'' is believed to be closely related to ''Meso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douc
The doucs or douc langurs make up the genus ''Pygathrix''. They are colobine Old World monkeys, native to Southeast Asia, which consists of these 3 species: red-shanked douc, black-shanked douc, and gray-shanked douc.

Microcolobus
''Microcolobus'' is an extinct genus of Old world monkey that lived in eastern Africa during the Late Miocene and is regarded as the first known member of the Colobinae. Taxonomy ''Microcolobus'' was described in 1986 from remains that were found in the Tugen Hills in Kenya and have been dated to between 10.5 and 8.5 million years ago. Fossils of this species (or a close relative) have also been found in Nakali.
