Sciurinae is a subfamily of squirrels, uniting the flying squirrels with certain related tree squirrels. Older sources place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.
Large black flying squirrel form a taxon of squirrels under the tribe Pteromyini. They are only found in South-east Asia.
The Namdapha flying squirrel is an arboreal, nocturnal flying squirrel endemic to Arunachal Pradesh in northeast India, where it is known from a single specimen collected in Namdapha National Park in 1981. No population estimate is available for B. biswasi, but the known habitat is tall Mesua ferrea jungles, often on hill slopes in the catchment area of Dihing River in northeastern India.
The groove-toothed flying squirrel or North Chinese flying squirrel is a species of rodent in the family Sciuridae. It is monotypic within the genus Aeretes. It is endemic to China, and occurs in Sichuan, Gansu, Hebei, and Beijing. Its natural habitat is temperate forests.
Thomas's flying squirrel is a species of rodent in the family Sciuridae. It is one of two species in the genus Aeromys. It is found in Indonesia and Malaysia.
The Mentawai squirrel is a species of rodent in the family Sciuridae. It is one of 20 or so species endemic to the Mentawai Islands off the west coast of Sumatra. There are three subspecies: C. m. melanogaster, C. m. mentawi, and C. m. atratus. This small isolated population is listed as "Vulnerable" by the IUCN due to habitat loss.
Prevost's squirrel or Asian tri-colored squirrel is a colourful species of rodent in the family Sciuridae. It is found in forests in the Thai-Malay Peninsula, Sumatra, Borneo and nearby smaller islands, with an introduced population in northern Sulawesi. Although the Prevost's squirrel is declining in some regions because of habitat loss and hunting, the species is not considered threatened since it generally remains common and widespread. It can live in somewhat disturbed habitats and often visits plantations or gardens. It mostly feeds on plant material, especially fruits, but also takes insects.
The Kashmir flying squirrel is a species of rodent in the family Sciuridae. It is monotypic within the genus Eoglaucomys. It is found in India and Pakistan. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. The Afghan flying squirrel is usually considered a subspecies.
Epixerus ebii, also known as Ebian's palm squirrel, Temminck's giant squirrel, or the western palm squirrel, is a species of rodent in the family Sciuridae. It is the only species in the genus Epixerus, although eastern populations were previously regarded as a separate species, E. wilsoni. It is found in West and Central Africa. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Layard's palm squirrel or flame-striped jungle squirrel is a species of rodent in the family Sciuridae endemic to Sri Lanka. The validity of the subspecies F. l. dravidianus based on a single specimen from the southern tip of India has been questioned, and is probably a juvenile F. sublineatus. Known as මූකලන් ලේනා in Sinhala.
The jungle palm squirrel, jungle striped squirrel, or Western Ghats squirrel is a species of rodent in the family Sciuridae endemic to India. Its natural habitats are subtropical or tropical dry forests, but it is tolerant to habitat changes and is also common in tea plantations in the Western Ghats. It is confined to forests with tall trees along the west coast of the Indian Peninsula. This confinement has led the jungle palm squirrel to be considered a pest on cacao, mangos, grapes, and sapota, plants that commonly grow in the type of forest. The ratio between males and females is not split evenly; males have been reported to have a larger population share. Potential factors for the uneven sex ratio include differences in "rate of persistence, mortality, dispersal, and predation pressure".
Thomas's rope squirrel or redless tree squirrel is a species of rodent in the family Sciuridae. It is found in Benin, Cameroon, Central African Republic, Democratic Republic of the Congo, Equatorial Guinea, Gabon, and Nigeria. Its natural habitat is subtropical or tropical moist lowland forests. It is a common species and the International Union for Conservation of Nature has rated it as being of "least concern".
Hodgson's giant flying squirrel is a species of rodent in the family Sciuridae. This large flying squirrel lives in Himalayan forests in Asia. Like other flying squirrels, it is nocturnal and able to glide long distances between trees by spreading out its patagium, skin between its limbs.
The Bhutan giant flying squirrel, also known as the Gray's giant flying squirrel or noble giant flying squirrel, is a species of rodent in the family Sciuridae. This species lives in Himalayan forests and it is one of the largest flying squirrels. Like other flying squirrels, it is mainly nocturnal and able to glide long distances between trees by spreading out its patagium, skin between its limbs.
The Basilan flying squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines. It is often confused with mindanao flying squirrel
The Siberut flying squirrel is a species of rodent in the family Sciuridae. It is endemic to Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The secretive dwarf squirrel is a species of rodent in the family Sciuridae. It is endemic to Sulawesi, Indonesia, where it is found on the Mengkoka Mountains in southeastern Sulawesi. Its natural habitat is montane forest. It is threatened by habitat loss.
Brooke's squirrel is a species of rodent in the family Sciuridae. It is found in Indonesia and Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It was named for Charles Brooke, the second White Rajah of Sarawak by Oldfield Thomas from a specimen collected by Charles Hose on Mt Dulit.
Jentink's squirrel is a species of rodent in the family Sciuridae. It is named in honor of the Dutch zoologist Fredericus Anna Jentink. It is found in Indonesia and Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
