Sundasciurus is a genus of rodent in the family Sciuridae. It contains 20 species:
The Davao squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines.
The fraternal squirrel is a species of rodent in the family Sciuridae. It is endemic to Indonesia, found only in the Mentawai Archipelago, located off the west coast of Sumatra.
The horse-tailed squirrel is a species of rodent in the family Sciuridae. It is found throughout the islands of Borneo and Sumatra, as well as the southern half of the Malay Peninsula, which includes the entire nations of Brunei and Malaysia, as well as some areas of Indonesia and Thailand. There was a mention of this squirrel being found in Vietnam in 1831, but subsequent descriptions of this squirrel's range have not included that nation.
Low's squirrel is a species of rodent in the family Sciuridae. It is found in Borneo and nearby islets. Its former subspecies S. l. robinsoni from Sumatra and the Malay Peninsula and S. l. natunensis from the Natuna islands have recently been given species status.
The Mindanao squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines.
The Culion tree squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines. Its natural habitat is subtropical or tropical dry forests.
The Philippine tree squirrel is a species of rodent in the family Sciuridae which is endemic to the Philippines.
The Palawan montane squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines. Its natural habitat is subtropical or tropical dry forests.
The Samar squirrel is a species of rodent in the family Sciuridae. It was historically known as lalagsing. It is endemic to the Philippines, where it has been recorded from Samar and Leyte Islands. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss, due to expanding human activities, hunting, and the lack of basic knowledge about the species. They thrive in primary and secondary lowland and montane forest, including the lower edges of mossy forest. It is also found in some agricultural areas.
The Southern Palawan tree squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines. Its natural habitat is subtropical or tropical dry forests.
The slender squirrel is a species of rodent in the family Sciuridae. It is arboreal and found in Indonesia, Singapore, Malaysia, and Thailand. The body is brown on the upper parts and light grey on the underparts. The body measures about 13–16 cm, with a slightly shorter slender tail. It feeds on soft bark, fruits and insects.
The Callosciurinae are an Asiatic subfamily of squirrels containing over 60 species named after the genus Callosciurus, which means "beautiful squirrels".
Sundasciurus robinsoni, or Robinson's squirrel, is a species of rodent in the family Sciuridae. It is found in Indonesia, Malaysia and Thailand. The species Sundasciurus robinsoni has a dorsum that ranges from medium brown with orange agouti to dark brown, and its venter ranges from white to pale yellow/buff white, with a reduction in the extent of this pale coloration and a lack of distinct margins in the case of S. r. vanakeni. Some populations have a grayish ventral coloration in limbs while others do not. It can be easily distinguished from other medium-sized western Sundaland Sundasciurus based on its ventral coloration and tail. All populations of S. fraterculus except Siberut, S. tahan, and S. altitudinis have a venter fur coloration homogeneously admixed with gray. The only other medium-sized squirrel found in syntopy, S. tenuis, is also usually ventrally darker and dorsally lighter, with reddish-brown coloration on the shoulders and hips, white/pallid yellow hair tips present on tail, and a relatively thinner and longer tail (85–95% of head-body length; than S. robinsoni. Males of S. fraterculus, S. tahan and S. tenuis have a darker orange wash in the scrotal area than S. robinsoni, which is peach colored.
Callosciurini is a tribe of tree squirrels mainly found in southern Asia.
The Sumatran mountain squirrel is a species of rodent in the family Sciuridae. Their skulls reach sizes between 41 - 43mm that overlap with those of the Palawan montane squirrel.
