Tenasserim lutung

The Tenasserim lutung, Trachypithecus barbei, is an Old World monkey found in Myanmar and Thailand and named after the Tenasserim Hills. Phylogenetic evidence indicates that it is an ancestor of the far more widespread Indochinese grey langur, Trachypithecus crepusculus, which is the product of ancient hybridization between the Tenasserim lutung and ancestral obscurus-group langurs. The English Wikipedia list of Old World monkeys records it as vulnerable and as a forest species that feeds on leaves, flowers and fruit.
