Shan Langur

The Shan langur (Trachypithecus melamera) occurs in eastern Myanmar (the Shan States) and south-west China (western Yunnan), between the Ayeyarwady and Thanlwin rivers. It was long treated as a subspecies of Phayre's leaf monkey and was recognised as a full species in a 2020 mitogenomic study. (Mammal Diversity Database; web search summary of Roos et al. 2020)

It has silvery-grey fur, a black face with pale skin around the eyes and mouth, long slender limbs and a pale grey or whitish underside, with a body length of about 55–71 cm, a tail of 60–80 cm and a weight of 7.2–10.5 kg. Langurs of this region live in habitats ranging from shrubby karst to closed-canopy forest, mostly fragmented or disturbed primary and secondary forest in a monsoon climate.
