Hose's langur (Presbytis hosei) is a species of primate in the Cercopithecidae family. It is endemic to the island of Borneo, including Brunei, Kalimantan (Indonesia), and East Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.[2]
Miller's grizzled langur, a subspecies, is very rare and had been thought to be extinct, until the press announced in January 2012 its "rediscovery".[3] Populations of Miller's grizzled langurs were first described in Kutai National Park and Sangkulirang Peninsula, East Kalimantan, Indonesia, in 1985.
In the past these primates had been hunted for their meat and occasional bezoar stones. Together with loss of natural habitats these populations have declined.
An international team of scientists from Indonesia, USA, Canada, and Czech Republic, have studied this new population and published their findings in the American Journal of Primatology.
Scientists had set up time-lapse recording equipment in the Wehea forest of the eastern tip of Borneo island, in June 2011. They discovered in over 4,000 of their images the primate, which was so rare it took efforts for the scientists to verify from old pictures what they had discovered. This area of forest is apparently outside of the primates' previous known range, being north-eastern part of Borneo, as well as the islands of Sumatra and Java and the Thai-Malay peninsula.[4][5]
