Grey langur or th Nilgiri langur

Gray langurs or Hanuman langurs, the most widespread langurs of South Asia, are a group of Old World monkeys constituting the entirety of the genus Semnopithecus. All taxa have traditionally been placed in the single species Semnopithecus entellus.[1] In 2001, it was recommended that several distinctive former subspecies should be given full species status, so that seven species are recognized.[2] A taxonomic classification with fewer species has also been proposed.[3] Genetic evidence suggests that the Nilgiri langur and purple-faced langur, which usually are placed in the genus Trachypithecus, actually belong in Semnopithecus.
