 The inland forest bat "Vespadelus baverstocki" is distinguished by its smaller size in their common range to the north, and is paler in colour and lacks the distinct fold at the glans penis.The related bats of genus "Vespadelus", the eastern forest bat "V. pumilus" and large forest species "V. darlingtoni", are distinctly darker in skin colour and their penis is bent at an acute angle.The structural characteristics of their ultrasound calls are able to be discerned in sonograms, although imperfect recording conditions may not allow them to be distinguished from some other vespadeluses.
