Purple-faced langur

The purple-faced langur , also known as the purple-faced leaf monkey, is a species of Old World monkey that is endemic to Sri Lanka. The animal is a long-tailed arboreal species, identified by a mostly brown appearance, dark face and a very shy nature. The species was once highly prevalent, found in suburban Colombo and the "wet zone" villages , but rapid urbanization has led to a significant decrease in the population level of the monkeys. It had traditionally been classified within the lutung genus ''Trachypithecus'' but was moved to the genus ''Semnopithecus'' based on DNA evidence indicating that is it more closely related to the gray langurs.

In Sinhala it is known as ශ්‍රී ලංකා කලු වදුරා .
