[2] [3] Their German name of Mützenlanguren ("capped langurs") comes from the hair on their head, which forms a tuft. They differ from the other langurs by characteristics in the shape of their head (particularly the poorly developed or absent brow ridges, and the prominent nasal bones), [2] in the teeth, and by the size of their small thumbs ...
Gray langurs have stable populations in some areas and declining ones in others. [62] Both the black-footed gray langur and Kashmir gray langur are considered threatened. [3] [20] The latter is the rarest species of gray langur, with less than 250 mature individuals remaining. [3] In India, gray langurs number at around 300,000. [63]
The name "lutung" comes from the Sundanese language meaning "blackness", ultimately from Proto-Austronesian *luCuŋ (which originally referred to the Formosan rock macaque); [2] it is preferred in one paper because the authors wanted the name langurs to only refer to monkeys in the genus Semnopithecus, [3] although some "lutungs" are now ...
Black-footed gray langur, (Semnopithecus hypoleucos) Nilgiri langur (Trachypithecus johnii) Two subfamilies are recognized, the Cercopithecinae, which are mainly African, but include the diverse genus of macaques, which are Asian and North African, and the Colobinae, which includes most of the Asian genera, but also the African colobus monkeys.
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
The Tenasserim lutung (Trachypithecus barbei) is a species of Old World monkey.It is found in Myanmar and Thailand.. It is named after the Tenasserim Hills.. Phylogenetic evidence indicates that the Tenasserim lutung is an ancestor of the far more widespread Indochinese grey langur (T. crepusculus), with T. crepusculus being a product of ancient hybridization between the Tenasserim lutung and ...
