Callosciurus is a genus of squirrels found mainly in Southeast Asia, though a few species also occur in Nepal, northeastern India, Bangladesh and southern China.[1] Several of the species have settled on islands. In total, the genus contains 15 species and numerous varieties and subspecies.[1] The genera Glyphotes, Rubrisciurus, and Tamiops have sometimes been included in Callosciurus.

Most species are overall rather dull olive-brown to gray and several have a pale and dark stripe on their side, but a few are very colorful;[2] in fact, they belong to the most colorful mammals. The Pallas's squirrel has an unremarkable olive-gray back, but its belly is often –but not always– bright red.[3] The "typical" subspecies of Prevost's squirrel have a black back, white sides, and red-brown underside. The Finlayson's squirrel occurs in numerous varieties, three of which are overall red-brown, overall black, or pure white.[2] The length of these squirrels is between 13 and 27 cm (5.1 and 11 in), not including the 13 to 27 cm (5.1 to 11 in) long tail.[2][4]

Most squirrels in Callosciurus live in tropical rain forests, but some individuals live in parks and gardens in cities. In the trees, they build their nests out of plant material. They are solitary, and give birth to one to five young. Their food consists of nuts, fruits, and seeds, and also of insects and bird eggs.

* Callosciurus adamsi (Kloss, 1921), ear-spot squirrel: northern Borneo.

* Callosciurus baluensis (Bonhote, 1901), Kinabalu squirrel: northeastern Borneo.

* Callosciurus caniceps (Gray, 1842), gray-bellied squirrel: Myanmar, Thailand, Malay Peninsula.

* Callosciurus erythraeus (Pallas, 1779), Pallas's squirrel: southern China including Hainan, Taiwan, Indochina; introduced to Argentina, Belgium, France and Japan.[5]

* Callosciurus finlaysonii (Horsfield, 1824), Finlayson's squirrel: Myanmar, Thailand, Cambodia.

* Callosciurus inornatus (Gray, 1867), inornate squirrel, Yunnan (China), Laos, Vietnam.

* Callosciurus melanogaster (Thomas, 1895), Mentawai squirrel: Mentawai Islands.

* Callosciurus nigrovittatus (Horsfield, 1824), black-striped squirrel; Malay Peninsula, Java, Sumatra, Borneo, numerous small islands.

* Callosciurus notatus (Boddaert, 1785), plantain squirrel: Malay Peninsula, Singapore, Java, Sumatra, Borneo, Bali, Lombok, numerous small islands.

* Callosciurus orestes (Thomas, 1895), Borneo black-banded squirrel: northwestern Borneo.

* Callosciurus phayrei (Blyth, 1856), Phayre's squirrel: southern Myanmar.

* Callosciurus prevostii (Desmarest, 1822), Prevost's squirrel: Malay Peninsula, Sumatra, Borneo, numerous small islands; introduced to Sulawesi.
