In 2006, the bat was rediscovered in the Santa Cruz Department of Bolivia by scientists Aideé Vargas and Kathrin Barboza Marquez. Prior to their find, it was believed that the bat had been extinct in Bolivia for 72 years. There has since been an Ecological Sanctuary established at the town of San Juan de Corralito located in the Ángel Sandoval Province to protect the species.[2]

Description

Its ears are long with sharply-pointed tips. It has a large nose-leaf of up to 20 mm (0.79 in). Its fur is dark brown or black in color, while the patagia are black. The forearm is 47–57 mm (1.9–2.2 in). Individuals weigh 10–22 g (0.35–0.78 oz). Its dental formula is 2.1.2.32.1.3.3 for a total of 34 teeth.[3]

Biology and ecology

It is insectivorous, though a record exists of one individual eating fruit. It is nocturnal, roosting in sheltered places during the day such as caves or culverts. These roosts contain 10-500 individuals in associations called colonies. Roosts are shared with bats of other species.[3]

Range and habitat

It is found in several countries in Central and South America including: Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname, Trinidad and Tobago, and Venezuela. It has been documented in lowlands and at elevations up to 1,500 m (4,900 ft) above sea level.[1]

Conservation

As of 2015, it is evaluated as a least-concern species by the IUCN. It meets the criteria for this category because it has a wide geographic range and is unlikely to be experiencing rapid population decline.[1]

gollark: That can't really be done very well. Or, it sort of can, but it would be possible to infer many achievements.
gollark: > <@!258639553357676545> dont. do NOT spoil spoilers.I can't just somehow not share the achievement code but keep bot contributions possible.
gollark: Oh BEE the network connection.
