|Scientific Name:||Myotis keaysi J.A. Allen, 1914|
|Taxonomic Notes:||Apparently closely related to riparius and ruber.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Barquez, R. & Diaz, M.|
|Contributor(s):||Perez, S. & Miller, B.|
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Previously published Red List assessments:|
|Range Description:||The species is found from Tamaulipas (southern Mexico) to Bolivia, Northern Argentina, Peru, Ecuador, Venezuela, and Trinidad (Simmons 2005).|

|Population:||Through its wide distribution, this species appears to be locally common at higher elevations (above 1,000 m).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Same as most vespertilionids, this is an insectivorous bat. Despite its large distribution, its biology is poorly known, bat surveys show this species is associated to Andean forests over 1000 m (Barquez et al. 1999, Wilson 2008). In Colombia, it has been reported associated to oak forests (Mantilla-Meluk and Muñoz 2014). This species is known to form small colonies in hollow trees (Wilson 2008).|
|Major Threat(s):||There are no major threats to this species.|
|Conservation Actions:||This species shows a large latitudinal and elevational distribution, from southern Mexico to northern Argentina; at the several countries it occupies, it is found in a number of protected areas. However, at the higher elevations of the Andes, loss of native forests should be avoided as this species depends on those ecosystems.|
