Grandidier's trident bat is recorded in northern Madagascar. It has pale yellow-brown fur and a noseleaf with three pointed tips.
Its fur is pale yellow-brown, slightly lighter underneath. The ears are funnel-shaped, and the upper lobe of its noseleaf divides into three narrow, straight points.
It is described as foraging in dry forest and roosting in caves. A northern Madagascar inventory captured bats as they entered or left a cave.
