Sciurinae
Sciurinae is a subfamily of squirrels (in the family Sciuridae), 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.

Sciurini
Sciurini is a tribe that includes about forty species of squirrels,Thorington and Hoffmann, 2005, p. 754 mostly from the Americas. It includes five living genera—the American dwarf squirrels, '' Microsciurus''; the Bornean ''Rheithrosciurus''; the widespread American and Eurasian tree squirrels of the genus '' Sciurus'', which includes some of the best known squirrel species; the Central American '' Syntheosciurus''; and the American pine squirrels, ''Tamiasciurus''. Like other arboreal squirrels, they are sometimes referred to as tree squirrels. Taxonomy The name "Sciurini" was first employed by Hermann Burmeister in 1854, who used it for the entire squirrel family. In his influential 1945 classification of mammals, George Gaylord Simpson included four genera of squirrels in Sciurini, which he recognized as one of eight tribes within the subfamily Sciurinae (including all squirrels except the flying squirrels): '' Sciurus'', '' Syntheosciurus'', '' Microsciurus'', and '' ...

Squirrel
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, c ...

Microsciurus
''Microsciurus'' or dwarf squirrels is a genus of squirrels from the tropical regions of Central and South America. Taxonomy and systematics Recent DNA analysis has shown that there is some confusion regarding the traditional classification of the species in the genus ''Microsciurus'', and that the genus may be polyphyletic. Currently, there are four species recognized: *Central American dwarf squirrel (''Microsciurus alfari'') Allen, 1895, Costa Rica, Nicaragua, Panama, northern Colombia *Amazon dwarf squirrel (''Microsciurus flaviventer'') Gray, 1867, western Amazon basin *Western dwarf squirrel (''Microsciurus mimulus'') Thomas, 1898, Ecuador, Colombia, Panama *Santander dwarf squirrel (''Microsciurus santanderensis'') Hernández-Camacho, 1957, central Colombia A 2020 paper published on the taxonomy of Sciurinae split ''Microsciurus'' into three genera, one currently unnamed. The paper included genetic sampling from all species except Santander dwarf squirrel and '' (Micro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sciurus
The genus ''Sciurus'' contains most of the common, bushy-tailed squirrels in North America, Europe, temperate Asia, Central America and South America. Species The number of species in the genus is subject to change.

Eoglaucomys
The Kashmir flying squirrel (''Eoglaucomys fimbriatus'') is a species of rodent in the family Sciuridae. It is monotypic within the genus ''Eoglaucomys''. It is found in Afghanistan, India and Pakistan. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.

Pteromyscus
The smoky flying squirrel (''Pteromyscus pulverulentus'') is a species of rodent in the family Sciuridae. It is monotypic within the genus ''Pteromyscus''. It is found in parts of Brunei, Indonesia, Peninsular Malaysia, and southern Thailand, but its range may be more extensive than currently mapped. Their natural habitat is subtropical or tropical dry forests. It is listed as an endangered species because of estimated population loss of 50% in past and future, judging from extensive and rapid habitat loss. Its average body length ranges from 22 centimetres to 29 centimetres (cm). Their tails range from 18 to 23 centimetres, feet range from 38 to 45 millimetres (mm), and ears range from 17 to 23 millimetres. In total, the smoky flying squirrel weights approximately 5 to 9 ounces (oz).

Trogopterus
The complex-toothed flying squirrel (''Trogopterus xanthipes'') occurs in the southern Chinese provinces Hubei, Hunan, Guizhou, Sichuan, and Yunnan. The common name refers to the teeth, which differ from those of other species of flying squirrels. Description ''Trogopterus xanthipes'' looks much like other flying squirrels, but with a characteristic tuft of black hair below the base of the ear. The fur is generally grey-brown, but white beneath. There is a slight reddish tinge to the face and the tail. The overall length is about 60 cm, of which the tail is about half. Conservation The conservation status of the complex-toothed flying squirrel is ''near threatened'' because the population is shrinking as a result of habitat loss and excessive hunting for food and traditional Chinese medicine. The droppings of the flying squirrel are made into a tea used in traditional medicine in parts of China. With the initial purpose of improve living and mating conditions for the fragme ...

Syntheosciurus
Bangs's mountain squirrel (''Syntheosciurus brochus'') is a poorly known species of tree squirrel, that only lives in Costa Rica and Panama. It can be found in mountain rain forests at an altitude between , and lives mainly in the tree tops, but sometimes on the forest floor as well. One of its habitats is at the summit of the Poás Volcano in Costa Rica, in a Clusia forest that is almost inaccessible to humans. Description The squirrel's head and body measure , with a tail. It has an olive brown back and an orange-red belly. Because of the shape of its skull and teeth, the species has been separated from the genus of typical tree squirrels, ''Sciurus The genus ''Sciurus'' contains most of the common, bushy-tailed squirrels in North America, Europe, temperate Asia, Central America and South America.

Petaurista
''Petaurista'' is a genus of rodent in the family Sciuridae. They are large to very large flying squirrels found in forests and other wooded habitats in southern and eastern Asia. Like other flying squirrels, they are mostly nocturnal and able to glide (not actually fly like a bat) long distances between trees by spreading out their patagium, skin between their limbs. They feed primarily on plant material, but will also take small animals such as insects. Taxonomy The species level taxonomy is very complex and not fully resolved. In 2005, ''Mammal Species of the World'' recognised eight species, but later studies have found that some of these were highly polyphyletic, and recent authorities have often recognised some of the most divergent "subspecies" as valid species. Additionally, three new species were described from northeastern India in 2007–2013, although their validity needs to be confirmed.
