See text Vespadelus is a genus of Australian bats in the family Vespertilionidae.

The genus name was first published by Ellis Le Geyt Troughton and Tom Iredale in 1934, but without an adequate description; the type was cited as Scotophilus pumilus Gray, 1841.

[2] The 1934 review included taxa previously ascribed to other genera and placed these with the proposed arrangement, the type species was assigned to a new combination as Vespadelus pumilus.

The separation to this genus followed comparative studies that recognised its diversity and nominated new species (Kitchener, 1987; Queale.).

Subsequent authors recognition of the arrangement published as Vespadelus by Troughton in 1943 saw the name of this genus reëstablished.
