Taxonomy

It was described as a new species in 1835 by German zoologist Eduard Friedrich Poeppig. Poeppig placed it in the genus Nycticeius, with a binomial of N. macrotus.[2] By 1875, it was published under its current name combination, Histiotus macrotus.[3]

Description

It has large ears that exceed 33 mm (1.3 in) in length.[4] The fur on its back is dark brown, while its belly fur is whitish. The flight membranes and ears are the darkest parts of its body.[5]

Range and habitat

It is found in South America, where its range includes Argentina, Chile, and Paraguay. One study published that the species was found in Peru, though the image of the specimen did not appear to show the big-eared brown bat. It has been documented at a range of elevations from 240–3,600 m (790–11,810 ft) above sea level.[1]

Conservation

As of 2016, it is evaluated as a least-concern species by the IUCN. It meets the criteria for this classification because it is adaptable to a variety of habitats; its population is presumably large; and it is unlikely to be experiencing rapid population decline.[1]

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.
