Source-backed taxonomic record
Accepted species in Catalogue of Life’s 11 September 2026 base release. This preserves the source classification and available supporting data; it is not a completed species monograph.
Open encyclopedia reference
The Tenasserim lutung (Trachypithecus barbei) is a species of Old World monkey. It is found in Myanmar and Thailand.
It is named after the Tenasserim Hills.
Phylogenetic evidence indicates that the Tenasserim lutung is an ancestor of the far more widespread Indochinese grey langur (T. crepusculus), with T. crepusculus being a product of ancient hybridization between the Tenasserim lutung and ancestral obscurus-group langurs.
