# Tarsius

Tarsius is a genus of tarsiers, small primates native to islands of Maritime Southeast Asia, with almost all of its species found on Sulawesi Island. Until 2010, all tarsier species were typically assigned to this genus, but a revision of the family Tarsiidae restored the generic status of Cephalopachus and created a new genus Carlito.
All members of Tarsius are found on Sulawesi, while Cephalopachus is found on Sundaland and Carlito in Greater Mindanao.
