The Keast's Tube-nosed Fruit Bat (Nyctimene keasti) is a species of megabat in the Pteropodidae family found in Babar, Tanimbar, and the Kai Islands.
In 1851 William Bullock Clark treated the Pteropoda as a family and emended the spelling to Pteropodidae (a name now used for a family of fruit bats)
