binomial_authority = (Erxleben, 1777)The Purple-faced Langur ("Trachypithecus vetulus"), or Purple-faced Leaf Monkey, is a species of
Old World monkey endemic toSri Lanka .This is a long-tailed
arboreal species, mainly brown with a dark facemask and paler lower face. The loud barking call, particularly of the highland form, can be mistaken for the roar of a predator such as aLeopard .This was once a common species, which was found even in suburban
Colombo and in the wet zone villages, but rapidurbanisation has taken a toll on the numbers of these monkeys.It is said to be very selective in its diet, and its range has contracted greatly in the face of human encroachment, although it can still be seen in Sinharaja,
Kitulgala , in the mountains atHorton Plains National Park or in the rainforest city ofGalle .There are four distinct
subspecies of Purple-faced Langur:
*Southern Lowland Wetzone Purple-faced Langur , "Trachypithecus vetulus vetulus"
*North Lowland Wetzone Purple-faced Langur , "Trachypithecus vetulus nestor"
*Dryzone Purple-faced Langur , "Trachypithecus vetulus philbricki"
*Montane Purple-faced Langur or Bear Monkey, "Trachypithecus vetulus monticola"References
