Banded Surili
Presbytis femoralis
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. The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species. As a result, the Raffles' banded langur meets the criteria for being listed as critically endangered by the IUCN. It is mainly threatened by habitat loss.

Description
The Raffles' banded langur is 43.2 to 61.0 cm (17.0 to 24.0 in) long, excluding the tail, with a tail length of 61.0 to 83.8 cm (24.0 to 33.0 in). It weighs 5.9 to 8.2 kg (13 to 18 lb). It has dark fur on the back and sides with white-colored fur forming a band on the chest and along the inner thighs.
What it does
The Raffles' banded langur has a primarily vegetarian diet. Specialized bacteria in its gut allow it to digest leaves and unripe fruit. The Perawang study found that nearly 60% of the diet consisted of fruits and seeds. Another 30% consisted of leaves, primarily young leaves. A different study found that fruit made up 49% of the diet. Unlike some other monkeys, such as the long-tailed macaque, the banded langur destroys the seeds it eats, and thus is not a significant factor in dispersing seeds.
