Trachypithecus

Trachypithecus is a genus of Old World monkeys containing species known as lutungs, langurs, or leaf monkeys. 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. The scientific name of the genus comes from the Ancient Greek τραχύς (trakhús), meaning "rough", and πίθηκος (píthēkos), meaning "monkey".
