Banded surili

Presbytis femoralis

Banded surili is an Old World monkey in the family Cercopithecidae (order Primates) — Presbytis femoralis, recorded as Critically Endangered.

Status

Appearance

It has dark fur on the back and sides with white-colored fur forming a band on the chest and along the inner thighs.

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).

Range and habitat

It is endemic to Singapore and southern peninsular Malaysia. It is mainly threatened by habitat loss.

The Raffles' banded langur was once common throughout the island of Singapore but that population is now listed as critically endangered, with approximately 60 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.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Diet

The Raffles' banded langur has a primarily vegetarian diet. The Perawang study found that nearly 60% of the diet consisted of fruits and seeds.

A different study found that fruit made up 49% of the diet.

In crisis

As a result, the Raffles' banded langur meets the criteria for being listed as critically endangered by the IUCN. The IUCN assessed Banded surili as being critically endangered in 2021. After the taxonomic reassessment, there are only about 300–400 Raffles' banded langurs remaining—about 250 to 300 and possibly fewer in peninsular Malaysia and about 60 in Singapore.

As a result of the small, fragmented population and continuing risk of further deforestation, the species meets the criteria to be listed as critically endangered by IUCN. The Central Catchment population had declined to as few as 10–15 monkeys before recovering to about 40 by 2012, 60 by 2019, and about 70 by 2022.

CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
