Phayre's leaf monkey
Phayre's leaf monkey ("Trachypithecus phayrei"), also known as Phayre's langur, is a species of lutung native to South and Southeast Asia, namely India, Bangladesh and Myanmar. Populations from further east are now thought to belong to other species. It is listed as Endangered on the IUCN Red List and is threatened by hunting and loss of habitat. The species epithet commemorates Arthur Purves Phayre. Taxonomy. Phayre's langur is one of the most widespread members of the genus, but its actual distribution and intraspecific taxonomy remain controversial. Previously, three subspecies were recognized ("T. p.  crepusculus", "T. p. phayrei", and "T. p. shanicus") but the IUCN Red List and American Society of Mammalogists now recognize "T. crepusculus" as a distinct species, the Indochinese grey langur. A 2020 reassessment based on mitochondrial genomes proposes a further split into three separate species: "T. phayrei", "T. melamera" (formerly "T. p. shanicus"), and "T. popa sp. nov.". Behaviour and ecology. It is mostly arboreal, and feeds on leaves of many tree species. In Tripura, India, it mainly feeds on leaves of "Albizia procera", "Albizzia lebbek" and "A. stipulata", "Melocanna bambusoides", "Macaranga denticulata", "Callicarpa arborea", "Dillenia pentagyna", "Litsea" sp., "Mikania  scandens", "Gmelina arborea", "Artocarpus chaplasha", "Syzygium fruticosum", "Ficus racemosa", "Ficus hispida", "Ficus indica", and "F. fistulosa".
