Species of Thailand
Binomial name: Presbytis femoralis, William Charles Linnaeus Martin, 1838
The banded surili (Presbytis femoralis), also known as the banded leaf monkey or banded langur, is a species of primate in the Cercopithecidae family. It is endemic to the Thai-Malay Peninsula and the Indonesia island of Sumatra. It is threatened by habitat loss. Three subspecies, femoralis (nominate), robinsoni and percura, are recognized here, but the taxonomy is complex and disputed, and it has also included P. natunae, P. siamensis and P. chrysomelas as subspecies, or alternatively all these (including P. femoralis) have been considered subspecies of P. melalophos. It is diurnal and eats fruit.
In Singapore, the banded leaf monkey is critically endangered with a population of approximately 40 individuals left in the Central Catchment Nature Reserve. The species was formerly found in the Bukit Timah Nature Reserve, but that population died out in 1987. The last individual to live in Bukit Timah is now displayed at the Raffles Museum of Biodiversity Research. The main threat to the Singapore population appears to be habitat loss. The National Biodiversity Centre, in partnership with the Evolution Lab of the National University of Singapore, launched an ecological study to determine suitable conservation strategies.
