The snout is pointed with an upturned tip, and the lower jaw is longer and narrower than is typical in free-tailed bats.

As the common name of the bat suggests, the ears are unusually wide and rounded, and they join together in the middle of the forehead.

[2] Broad-eared bats are found in tropical and subtropical forests from coastal Mexico to southern Brazil.

[1] Five subspecies are recognised:[2] Broad-eared bats are nocturnal, and roost during the day in rocky crevices in tightly packed groups of anything from 150 to 1,000 individuals.

[2] Broad-nosed bats breed in the rainy season, giving birth between June and July in the northern parts of their range, and later in the year further south.
