The Natuna Island surili (Presbytis natunae) is a species of primate in the family Cercopithecidae.
The species is endemic to the Indonesian island of Natuna Besar. [1] It was separated from P. siamensis by Groves in 2001. [1]
A study published in 2003 [3] estimates the population to be less than 10,000 as of 2002, the main threat being heavy logging since 1980.
Natuna Regency is an islands regency located in the northernmost part of the Province of Riau Islands. It contains at least 154 islands, of which 127 of them are reported as uninhabited. This archipelago, with 264,198.37 km2 area, contains the island district of Pulau Laut, Bunguran/Greater Natuna Island, the island district of Pulau Tiga, the island district of Midai, the island district of Subi, and the island district of Serasan.
The surilis are a group of Old World monkeys in the genus Presbytis. They live in the Thai-Malay Peninsula, on Sumatra, Borneo, Java and smaller nearby islands. Besides surili, the common names for the monkeys in the genus also sometimes use the terms "langur" or "leaf monkey."
The Javan surili is a vulnerable species of Old World monkey endemic to the western half of Java, Indonesia, a biodiversity hotspot. Other common names by which it is known by include gray, grizzled or Sunda Island surili; grizzled or stripe-crested langur; Javan grizzled langur; grizzled, Java or Javan leaf monkey; langur gris.
Great Natuna Island or just Natuna is the main island of the Middle Natuna Archipelago, which is part of the Riau Islands Province, Indonesia. It is also called Great Bunguran Island.
Leptobrachella natunae is a species of amphibian in the family Megophryidae. It is endemic to Natuna Besar in the Natuna Islands (Indonesia) of South China Sea. It has not been recorded after its description, more than a century ago. Its natural habitats are tropical moist lowland forests and rivers.
The white-fronted surili is a species of primate in the family Cercopithecidae, the Old World monkeys. It is endemic to the large international island of Borneo, in Indonesia, Malaysia, and possibly Brunei.
Hose's langur is a species of primate in the family Cercopithecidae endemic to the island of Borneo, including Brunei, Kalimantan (Indonesia), and East Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It was first identified in Kutai National Park and Sangkulirang Peninsula, East Kalimantan, Indonesia, in 1985.
The black-crested Sumatran langur is a species of primate in the family Cercopithecidae. It is endemic to Sumatra in Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The Mentawai langur is a species of primate in the family Cercopithecidae. It is endemic to the Mentawai Islands in Indonesia. Its natural habitat is subtropical or tropical dry forests. The Siberut langur was formerly considered a subspecies of the Mentawai langur.
The maroon langur, maroon leaf monkey, or red leaf monkey is a member of the family Cercopithecidae. It is found on the southeast Asian island of Borneo and the nearby smaller Karimata. P. rubicunda mostly live in forests at altitudes below 2,000 m. They feed on leaves, seeds, and fruits.
The white-thighed surili is a species of primate from the family of old world monkeys (Cercopithecidae). This species lives arboreal amongst the sub-montane forests. It is endemic to the Thai-Malay Peninsula, the Riau Archipelago and Sumatra. In addition, the white-thighed surili contain four subspecies: siamensis (nominate), cana, paenulata and rhionis, are recognized here. Furthermore, they are characterized by the white patches located on the outside of their legs, which is what gives them their name. Additionally, they can be referred to as pale-thighed langur/surili. These primates are an important species for the diversity of forest environments in the Malaysian area.
The Sarawak surili is a species of primate in the family Cercopithecidae. It is endemic to the southeast Asian island of Borneo, where it is distributed north of the Kapuas River in Kalimantan, Indonesia, the Malaysia states of Sarawak and Sabah, and in Brunei. Its taxonomy is complex and disputed, and it has been considered a subspecies of P. femoralis or P. melalophos. The Sarawak surili was formerly considered common, but has declined drastically due to persecution and habitat loss, and as of 2008 is only known from five sites with a combined population of 200–500 individuals. Consequently, it is believed to be one of the rarest primates in the world, and has been rated as critically endangered by IUCN.
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation,, since then they have been published as independent publications.
The East Sumatran banded langur, 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. Its range is restricted to the Riau Province of east-central Sumatra. Due to its declining population and restricted range in small, isolated forests subject to high rates of deforestation, the IUCN declared it to be a critically endangered species in 2020.
The mitered langur is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Sumatran surili, Presbytis melalophos but genetic analysis revealed that these are separate species. The mitered langur is native to the island of Sumatra in Indonesia. It is listed as endangered by the IUCN due primarily to deforestation, and also due to animals taken for pets.
The black-and-white langur is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Black-crested Sumatran langur, Presbytis melalophos but genetic analysis revealed that these are separate species.
The black Sumatran langur is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Sumatran surili, Presbytis melalophos but genetic analysis revealed that these are separate species. The black Sumatran langur is native to the island of Sumatra in Indonesia. It is listed as endangered by the IUCN due primarily to deforestation, and also due to animals taken for pets.
Miller's langur, also known as Miller's grizzled langur or Kutai grey langur, is a species of leaf monkey. It is endemic to East Kalimantan on the island of Borneo in Indonesia. It is one of the world's most endangered primates, and was at one time thought to be extinct, until it was rediscovered in 2013.
