Histiotus is a genus of South American vesper bats with species that include:
- Strange big-eared brown bat (Histiotus alienus)
- Humboldt big-eared brown bat (Histiotus humboldti)
- Thomas's big-eared brown bat (Histiotus laephotis)
- Big-eared brown bat (Histiotus macrotus)
- Southern big-eared brown bat (Histiotus magellanicus)
- Small big-eared brown bat (Histiotus montanus)
- Tropical big-eared brown bat (Histiotus velatus)
The bat or the order Chiroptera is the second-largest mammalian order and represents more than half of all mammalian species in many neo-tropical communities. Bats have been found to be abundant in the tropics and contribute to patterns of species richness and diversity, yet most research of bat communities comes from studies done in North and Central America. Little information is known of the communities in the tropical and temperate zones. Most species of Histiotus are rare in Paraguay, known only from a few records, they are not abundant or widespread, and have been collected for the first time only recently. Researchers have been able to collect many of the Histiotus at human dwellings or around domestic animals, due to the significant increase in human activity in the Paraguayan Chaco over the last 20 years.
