Raffles Bindenlangur (Presbytis femoralis), auch einfach Bindenlangur oder Bänderlangur genannt, ist eine Primatenart aus der Gruppe der Schlankaffen (Presbytini).
Raffles Bindenlanguren haben ein dunkelgraues oder schwarzes Fell, der Bauch ist grau, wobei sich auf der Bauchmitte ein weißer Längsstreifen erstreckt. Arme und Beine, sowie der Schwanz sind wie der Rumpf gefärbt, wobei sich die Innenseiten von Armen und Beinen und die Unterseite des Schwanzes nicht hell absetzen, wie es bei vielen Affen der Fall ist. Die Brusthaare sind nach hinten gerichtet, die Bauchhaare nach vorne. Wo sie sich treffen bilden sie einen niedrigen Haarkamm.[1] Die Backen und die Ringe um die Augen sind meist hellgrau gefärbt. Wie alle Mützenlanguren sind sie relativ kleine, schlanke Primaten mit langen Hinterbeinen und einem langen Schwanz. Ihr Durchschnittsgewicht beträgt rund 6 Kilogramm. Individuen aus Singapur sind am Bauch dunkler gefärbt und für gewöhnlich etwas kleiner als die Tiere vom Malaiischen Festland.[1]
Raffles Bindenlanguren leben in Südostasien, im Süden der Malaiischen Halbinsel, im malaysischen Bundesstaat Johor und auf Singapur. Ihr Lebensraum sind Wälder, sowohl Primär- als auch Sekundärwälder. Sie sind tagaktive Baumbewohner und geschickte Kletterer, die sich entweder auf allen vieren oder springend durch das Geäst bewegen. Sie leben in Gruppen von 2 bis 8, manchmal bis zu 15 Tieren. Dies sind Haremsgruppen, sie bestehen also aus einem Männchen, mehreren Weibchen und dem dazugehörigen Nachwuchs. Diese Primaten sind Pflanzenfresser, die sich vorwiegend von jungen Blättern und Früchten ernähren.
Die Fortpflanzung kann das ganze Jahr über erfolgen, nach einer rund 168-tägigen Tragzeit bringt das Weibchen ein einzelnes Jungtier zur Welt. Dieses ist zunächst weißgrau gefärbt und wird für 10 bis 12 Monate gesäugt.
Raffles Bindenlangur wurde im Jahr 1838 durch den britischen Naturforscher William Charles Linnaeus Martin erstmals wissenschaftlich beschrieben und gilt heute als monotypisch, nachdem die ursprünglich zu Presbytis femoralis gezählten Unterarten seit 2001 bzw. 2020 als eigenständige Arten betrachtet werden. Dabei handelt es sich um den Sarawak-Langur (Presbytis chrysomelas), den Natuna-Langur (Presbytis natunae) und den Weißschenkligen Langur (Presbytis siamensis) und seit Juni 2020 auch um den Ostsumatra-Bindenlangur (Presbytis percura) und Robinsons Bindenlangur (Presbytis robinsoni).[2]
Raffles Bindenlangur ist stark gefährdet und der Bestand wird heute auf 250 bis 300 Tiere in Malaysia und 60 etwa Exemplare in Singapur geschätzt.[2]
Raffles Bindenlangur (Presbytis femoralis), auch einfach Bindenlangur oder Bänderlangur genannt, ist eine Primatenart aus der Gruppe der Schlankaffen (Presbytini).
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. 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.[2]
The taxonomy of Presbytis femoralis underwent several changes. Up until 2019, three subspecies of P. femoralis were recognized: P. f. femoralis (nominate), P. f. percura (the East Sumatran banded langur), and P. f. robinsoni (Robinson's banded langur).[1] Presbytis f. femoralis lives in Singapore, and in the states of Johor and Pahang of southern Peninsular Malaysia, P. f. robinsoni lives in the northern Malay Peninsula, including southern Myanmar and Thailand, and P. f. percura lives in east-central Sumatra.[2][3]
Genetic data suggested that at least P. f. femoralis and P. f. robinsoni were different species[4] which was also in agreement with their morphological characters. However, resolving all subspecies-level boundaries within banded langurs required data for P. f. percura, which was the least studied among them.[5] Most recently, mitochondrial genomes were obtained for P. f. percura, and based on multiple species delimitation algorithms (PTP, ABGD, Objective Clustering) applied to a dataset covering 39 species and 43 subspecies of Asian colobines, all three subspecies of banded langurs were resurrected to species.[6][7][8][9]
William Charles Linnaeus Martin formally described P. femoralis based on material that had been collected by Sir Stamford Raffles in Singapore.[10] Martin had given the distribution as "Sumatra etc.", not mentioning Singapore explicitly, resulting in some confusion over the actual type locality.[10][11] Gerrit Smith Miller Jr. resolved the issue in 1934, determining that Singapore was the actual type locality.[10][11]
The Raffles' banded langur is 43.2 to 61.0 centimetres (17.0 to 24.0 in) long, excluding the tail, with a tail length of 61.0 to 83.8 centimetres (24.0 to 33.0 in).[12] It weighs 5.9 to 8.2 kilograms (13 to 18 lb).[12] It has dark fur on the back and sides with white-colored fur forming a band on the chest and along the inner thighs.[4][11][13]
The Raffles' banded langur is diurnal and arboreal, preferring rainforest with trees of the family Dipterocarpaceae.[13][12] It comes to the ground less frequently than most other leaf monkeys.[14] It lives in both primary and secondary forest, and also in swamp forests and mangrove forests, and even in rubber plantations.[12] It moves primarily by walking on all fours and by leaping.[12]
According to wildlife researcher Charles Francis, it typically lives in groups of 3 to 6.[13] However, a study in Perawang, Sumatra found an average group size of 11 monkeys in mixed-sex groups.[15] The latter study also found an average ratio of 1 adult male to 4.8 adult females in mixed-sex groups and a ratio of 1.25 adult monkeys for every immature monkey in mixed-sex groups.[15] It also found an average range size for a group of 22 hectares, and an average population density of 42 monkeys per square kilometer.[15] Other studies found somewhat smaller home ranges, of between 9 and 21 hectares.[12]
The Raffles' banded langur appears to have two birth seasons, once between June and July and another between December and January.[16] In this study, at least six infants were born between 2008 and 2010, and the authors found low infant mortality, with several infants surviving at least to seven months old.[16] The study also found that the infant coloration of the Singapore population is indistinguishable from that of the Johor, Malaysia population, with infants having white fur with a black stripe down the back from the head to the tail, crossed by another black stripe across the shoulders and to the forearms.[16] Males leave their natal group before reaching maturity, at about 4 years old.[14]
The call of mature males sounds like "ke-ke-ke."[13] Mammalogist Ronald M. Nowak described the species' alarm call as "a harsh rattle followed by a loud chak-chak-chak-chak."
Raffles' banded langurs have occasionally been observed being groomed by long-tailed macaques.[17]
The Raffles' banded langur has a primarily vegetarian diet. Specialized bacteria in its gut allow it to digest leaves and unripe fruit.[14] The Perawang study found that nearly 60% of the diet consisted of fruits and seeds.[15] Another 30% consisted of leaves, primarily young leaves.[15] A different study found that fruit made up 49% of the diet.[12] Unlike some other monkeys, such as the long-tailed macaque, the banded langur destroys the seeds it eats, and so it is not a significant factor in dispersing seeds.[18]
The IUCN assessed Presbytis femoralis as being critically endangered in 2021. At the time they assessed the (then) subspecies P. f. femoralis as vulnerable.[2] After the taxonomic reassessment, there are only about 300–400 Raffles' banded langurs remaining—about 250 to 300 and possibly fewer in Malaysia and about 60 in Singapore.[6][19] 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.[6]
The Raffles' banded langur was once common throughout the island of Singapore but that population is now critically endangered with approximately 60 individuals left in the Central Catchment Nature Reserve.[6][20][21][22] The species was formerly found in the Bukit Timah Nature Reserve, but that population died out in 1987.[23] The last individual to live in Bukit Timah is now displayed at the Raffles Museum of Biodiversity Research.[23][24] The Central Catchment population had declined to as few as 10–15 monkeys before recovering to about 40 by 2012,[21] 60 by 2019.[6] and about 70 by 2022.[25]
The Singapore population feeds from at least 27 plant species, including Hevea brasiliensis leaves, Adinandra dumosa flowers and Nephelium lappaceum fruits.[3][4] They appear to prefer specific fruits and will travel long distances to reach their preferred fruit, rather than settle for more accessible foods.[22] 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. A 2012 study found extremely low genetic diversity within the remaining Singapore population and suggested that translocation of Raffles' banded langurs from Malaysia may be necessary to provide the Singapore population with enough genetic diversity to survive in the long run.[21] In 2016, a cross-border partnership between Singapore and Malaysia was formed with the establishment of a Raffles' Banded Langur Working Group funded by the Wildlife Reserves Singapore Conservation Fund.[4][26]
The main threat to the Singapore population appears to be habitat loss.[27] 99.8% of Singapore's original primary forest, including much of its dipterocarp flora, has been eliminated, with less than 200 ha remaining, primarily in Bukit Timah and the MacRitchie Reservoir and Nee Soon Swamp Forest portions of Central Catchment.[28] The Nee Soon Swamp Forest is the primary area of Central Catchment where the Raffles' banded langur is found.[29][30] The monkey groups inhabit forest fragments that have limited arboreal connections to other fragments.[4] Other contributors to the species' decline in Singapore have been hunting for food and the pet trade.[22] The species has been legally protected in Singapore since 1947.[28] The Singapore government hopes that the development of Thomson Nature Park near Central Catchment will help maintain the Raffles' banded langur population, since it is located near a traditional feeding area for the monkeys and will increase the forested area they can use.[31][32][33] Rope bridges are being used to facilitate movements between Central Catchment and nearby forest patches.[34] The government also hopes that eventually when the vegetation matures the Eco-Link@BKE will allow banded leaf monkeys to repopulate Bukit Timah.[35] A group of bachelor males once tried to make its way to Bukit Timah without using the EcoLink but one was killed crossing the highway and the group now lives in Windsor Nature Park.[36] In April 2021 a single Raffles' banded langur was observed in Bukit Timah but it is unclear whether it used the Eco-Link@BKE to get there.[37][38] The National Parks Board staff wrote of the sighting at the website of the Lee Kong Chian Natural History Museum.[38] Concerns have been raised as to whether construction of the Cross Island MRT line through Central Catchment may adversely impact the Raffles' banded langur population in the area.[39]
In 2020 a group of two dusky leaf monkeys was observed in Singapore, possibly having swum from Johor, and they were able to chase away a group of eleven Raffles' banded langurs that had been feeding on Adenanthera pavonina seeds.[40][41]

Il presbite di Raffles (Presbytis femoralis (Martin, 1838)), noto anche come presbite della Sonda, è una specie di primate della tribù dei Presbytini.
Il presbite di Raffles ha la pelliccia di colore grigio scuro o nero; la pancia è grigia con una striscia verticale bianca che si estende al centro di essa. Le braccia e le gambe, così come la coda, sono dello stesso colore del tronco, con la parte interna di braccia e gambe e quella inferiore della coda più chiare, come nel caso di molte scimmie. I peli del petto sono rivolti all'indietro, quelli del ventre in avanti: nel punto in cui si incontrano, formano una sorta di basso pettine[2]. Le guance e gli anelli intorno agli occhi sono generalmente di colore grigio chiaro. Come tutti i presbiti, è un primate relativamente piccolo e snello con lunghe zampe posteriori e una lunga coda. Il suo peso medio è di circa 6 chilogrammi. Gli esemplari di Singapore hanno la pancia di colore più scuro e di solito sono leggermente più piccoli di quelli che vivono sulla terraferma malese[2].
Il presbite di Raffles è originario del Sud-est asiatico; vive nel sud della penisola malese, nello stato malese di Johor e a Singapore. Il suo habitat è costituito dalle foreste, sia primarie che secondarie. Questo primate arboricolo e diurno è un abile arrampicatore che si sposta a quattro zampe o saltando tra i rami. Vive in gruppi composti da 2 a 8 esemplari, a volte fino a 15. I gruppi in realtà sono degli harem costituiti da un maschio, da diverse femmine e dalla loro prole. È un animale vegetariano e si nutre principalmente di giovani foglie e frutti.
La riproduzione può avvenire in qualsiasi periodo dell'anno. Dopo una gestazione di circa 168 giorni la femmina partorisce un solo piccolo. Inizialmente esso è di colore bianco-grigio e viene allattato per 10-12 mesi.
Il presbite di Raffles venne descritto scientificamente per la prima volta nel 1838 dal naturalista britannico William Charles Linnaeus Martin ed è attualmente considerato monotipico, dal momento che le varie sottospecie originariamente incluse in Presbytis femoralis sono state considerate specie separate nel 2001 e nel 2020. Si tratta per l'esattezza del presbite del Sarawak (Presbytis chrysomelas), del presbite di Natuna (Presbytis natunae) e del presbite del Siam (Presbytis siamensis) e, dal giugno 2020, anche del presbite di Sumatra orientale (Presbytis percura) e del presbite di Robinson (Presbytis robinsoni)[3].
Il presbite di Raffles è gravemente minacciato di estinzione: ne rimangono in tutto tra i 250 e i 300 esemplari in Malesia e circa 60 a Singapore[3].

Presbytis femoralis[2][3] (bandad bladapa [4]) är en däggdjursart som först beskrevs av Martin 1838. Presbytis femoralis ingår i släktet bladapor och familjen markattartade apor.[5][6] IUCN kategoriserar arten globalt som nära hotad på grund av utbredningsområdets omvandling till palmodlingar.[1] Det svenska trivialnamnet bandad bladapa förekommer för arten.[7]
Inga underarter finns listade i Catalogue of Life.[5] Wilson & Reeder (2005) skiljer mellan tre underarter.[8]
Arten når en kroppslängd (huvud och bål) av 46 till 59 cm[9] och en vikt av cirka 6 kg. Pälsens grundfärg är mörkbrun till svartaktig på ryggen och ljusare på buken. Några populationer har en tydlig längsgående vit strimma på buken och hos andra populationer förekommer vitaktiga eller blåa ringar kring ögonen. Ibland klassificeras de olika färgvarianterna som underarter.[10] Några individer har en eller två tofsar på huvudet (se bild).[7]
Denna primat förekommer på Malackahalvön och på nordcentrala Sumatra. Habitatet utgörs av mangroveskogar och av områden med buskar och gräs längs vattendrag. Arten äter huvudsakligen frukter samt några blad.[1]
Presbytis femoralis klättrar vanligen i växtligheten men den kommer ibland ner till marken. Födan utgörs främst av frukter och unga blad samt av frön och blommor. Individerna bildar flockar som har beroende på utbredningsområde 2 till 15 medlemmar. En vanlig flock består av en hane, några honor och deras ungar. Dessutom finns ungkarlsflockar. Arten är aktiv på dagen men den vilar vanligen under dagens hetaste timmar.[10]
Hos arten finns ingen särskild parningstid. Honor är ungefär varje månad för en vecka parningsberedda men mellan två födslar ligger två år. Dräktigheten varar i genomsnitt 168 dagar och sedan föds vanligen en unge, sällan tvillingar. Ungarna diar sin mor 10 till 12 månader. Äldre ungar uppfostras av hela flocken.[10]
