- Abstract
The East Sumatran Banded Langur Presbytis femoralis percura is a very little known colobine primate, endemic to Riau Province in Sumatra. Nothing much is known of its population size and distribution, except that it was confined in the area between Rokan and Siak rivers. We carried out an eight-day reconnaissance field trip and determined the presence of P. f. percura in seven locations in Riau Province, which extends south of the Siak River, beyond its previously reported range. We also obtained probably the first publicly available full-frontal coloured photos of the taxon in the wild, and photos of the Riau Pale-thighed Langur P. siamensis cana. Considering that the known populations of P. f. percura are restricted to small and isolated forest remnants, and that the remaining forests are rapidly being converted into oil palm plantations, we propose to change the listing of P. f. percura from Data Deficient to Endangered A2c. We recommend an immediate study on its population size and distribution in order to better understand its conservation needs and to protect this taxon. We further urge for more research and conservation attention on the non-human primates in Riau Province, Sumatra.
