The Raffles' banded langur (Presbytis femoralis), also known as the banded leaf monkey or banded surili, is a species of primate in the family Cercopithecidae. It is endemic to Singapore and southern Peninsular Malaysia. [2] The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species.
The black Sumatran langur, black-and-white langur, Sarawak surili, Raffles' banded langur and mitered langur were formerly considered subspecies of P. melalophos. [ 2 ] [ 3 ] References
The East Sumatran banded langur (Presbytis percura), also known as the East Sumatran banded surili, is a species of monkey in the family Cercopithecidae.It was formerly considered a subspecies of the Raffles' banded langur Presbytis femoralis, but genetic analysis revealed it to be a separate species.
Robinson's banded langur (Presbytis robinsoni), also known as Robinson's banded surili, is a species of monkey in the family Cercopithecidae.It was formerly considered a subspecies of the Raffles' banded langur Presbytis femoralis, but genetic analysis revealed that it is no more related to Raffles' banded langur than it is to several other Presbytis species.
[2] [3] Their German name of Mützenlanguren ("capped langurs") comes from the hair on their head, which forms a tuft. They differ from the other langurs by characteristics in the shape of their head (particularly the poorly developed or absent brow ridges, and the prominent nasal bones), [2] in the teeth, and by the size of their small thumbs ...

Through mitochondria DNA analysis, these three species are split into two separate clades: P. femoralis on its own, P. robinsoni and P. siamensis in the other. [2] This was due to the sharing of unique nucleotides between P. robinsoni and P. siamensis. [2] There continues to be ongoing evolution of Robinson's banded langur and the white-thighed ...
Authorities hope that when the trees mature, Raffles' banded langur monkeys will use the Eco-Link to expand their range into Bukit Timah. [2] [3] [7] Raffles' banded langur is critically endangered in Singapore, with only about 60 individuals remaining, and was eliminated from Bukit Timah in 1987.
