The least pygmy squirrel, also known as the plain pygmy squirrel, is a species of rodent in the family Sciuridae. This plain olive-brown squirrel is endemic to forests, mostly below an altitude of 750 m (2,500 ft) but locally significantly higher, on the Southeast Asian islands of Borneo, Sumatra and Banggi. Together with the African pygmy squirrel, the least pygmy squirrel is the smallest squirrel in the world, having a total length of 10–14 cm (3.9–5.5 in) and a weight of 12–26 g (0.42–0.92 oz).
Sanborn's squirrel is or was a little known tree squirrel described in 1944 from the skin and skeleton of a single female specimen collected in Peru in 1941. Subsequently over the proceeding years only a handful of either specimens were collected, or observations were recorded, in the regions of Madre de Dios and northern Puno in Peru, and Pando department in Bolivia. The 2019 IUCN assessment describes it as endemic to Peru. In 2015 this taxon was synonymised with Notosciurus pucheranii ssp. boliviensis. Its habitat is tropical dry broadleaf forests at elevations up to 570 m. It is considered possibly rare and potentially vulnerable to deforestation, but its population trend is not established.
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. It is threatened by habitat loss.
