Prosciurillus alstoni

Prosciurillus alstoni is a small squirrel of the family Sciuridae, in the subfamily Nannosciurinae, tribe Nannosciurini and genus Prosciurillus. John Anderson described it in 1879 as Sciurus alstoni; the type was said to come probably from Borneo, but in 2010 Musser and colleagues restricted the type locality to the Malakosa region of central Sulawesi, Indonesia. The Mammal Diversity Database records it as a living species found in the wild in the Australasian realm, with Indonesia as its country of distribution, notes that it was split from Prosciurillus leucomus, and lists its IUCN Red List status as Near Threatened.
