Taphozous is a genus of the family Emballonuridae. The wide distribution of the genus includes several regions of Australia, Indonesia, Papua New Guinea and Africa. Taphozous comes from the Greek τάφος, meaning "a tomb". The common names for species include variants on sac-winged, sheathtail, or tomb bats.
