Petaurista is a genus of rodent in the family Sciuridae.[1] They are large to very large flying squirrels found in forests and other wooded habitats in southern and eastern Asia.[2]

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.[2]
Taxonomy
edit
The species level taxonomy is very complex and not fully resolved.[3] In 2005, Mammal Species of the World recognised eight species,[4] but later studies have found that some of these were highly polyphyletic,[5][6][7][8] and recent authorities have often recognised some of the most divergent "subspecies" as valid species.[2][3][9] Additionally, three new species were described from northeastern India in 2007–2013, although their validity needs to be confirmed.[10]
Living species
editEight species were recognised in Mammal Species of the World in 2005:[4]
- Red and white giant flying squirrel, Petaurista alborufus Milne-Edwards, 1870
- Spotted giant flying squirrel, Petaurista elegans Müller, 1840
- Japanese giant flying squirrel, Petaurista leucogenys Temminck, 1827
- Hodgson's giant flying squirrel, Petaurista magnificus Hodgson, 1836
- Bhutan giant flying squirrel, Petaurista nobilis Gray, 1842
- Red giant flying squirrel, Petaurista petaurista Pallas, 1766
- Indian giant flying squirrel, Petaurista philippensis Elliot, 1839
- Chinese giant flying squirrel, Petaurista xanthotis Milne-Edwards, 1872
Seven additional species now often recognised, but traditionally considered subspecies:[3][8]
- White-bellied giant flying squirrel, Petaurista albiventer Gray, 1834
- Grey-headed giant flying squirrel, Petaurista caniceps Gray, 1842
- Formosan giant flying squirrel, Petaurista grandis Swinhoe, 1863
- Hainan giant flying squirrel, Petaurista hainana G. Allen, 1925
- Taiwan giant flying squirrel, Petaurista lena Thomas, 1907
- Spotted giant flying squirrel, Petaurista marica Thomas, 1912
- Chindwin giant flying squirrel, Petaurista sybilla Thomas and Wroughton, 1916
Three new species that were described by Anwaruddin Choudhury from Arunachal Pradesh in 2007–2013:[11][12][13]
- Mechuka giant flying squirrel, Petaurista mechukaensis Choudhury, 2007
- Mishmi giant flying squirrel, Petaurista mishmiensis Choudhury, 2009
- Mebo giant flying squirrel, Petaurista siangensis Choudhury, 2013
Extinct species
editIn addition to the living species, there are a few extinct species that only are known from fossil remains from the Mid and Late Pleistocene in China, the Russian Far East and Germany:[3][14]
- †Petaurista brachyodus Young, 1934
- †Petaurista helleri Dehm, 1962
- †Petaurista tetyukhensis Tiunov & Gimranov, 2019
