Six, possibly seven, species of non-human primates occur in Bhutan: slow loris (Nycticebus bengalensis), Assamese macaque (Macaca assamensis), Rhesus macaque (Macaca mulatto), Hanuman langur (Semnopithecus entellus), golden langur (Trachypithecus geei), and capped langur (Trachypithecus pileatus). A variant of the Assamese macaque, named Macaca munzala, has also been recorded there. Natural hybrids between golden and capped langur occur in an area in south-central Bhutan. The Assamese macaque is the most abundant and widespread primate, while slow loris is the least abundant, with a small range in Bhutan. Primates are not hunted for food in Bhutan, there are large areas of contiguous habitats for primates, and there is, besides, a good network of protected areas in the country. Overall, it would appear that primates have a secure future in Bhutan. The main conservation issues come from development, such as the construction of road networks and hydroelectric projects, grazing by domestic stock in some areas at high elevations, and people living in protected areas.
