What is "dizzya"

Dizzya is an extinct, monotypic genus of bat that occurred in the Chambi region, Tunisia, in the Middle Eocene. It was described based on a single upper molar, a lower dentary with two broken teeth, and a humerus. It is the smallest and, along with Witwatia sigei, the oldest representative of the Philisidae, an extinct family of bats related to the Vespertilionidae.
