Semnopithecus pallidus; Print; Gray langurs; sacred langurs; Indian langurs or Hanuman langurs are a group of Old World monkeys native to the Indian subcontinent constituting the entirety of the genus Semnopithecus. Most taxa have traditionally been placed in the single species Semnopithecus entellus. In 2001; it was recommended that several distinctive former subspecies should be given the status of species; so that seven species are recognized.A taxonomic classification with fewer species has also been proposed. Genetic evidence suggests that the Nilgiri langur and purple-faced langur; which usually are placed in the genus Trachypithecus; actually belong in Semnopithecus.; 1749-1842
