Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2016
Date Assessed:	2016-07-01
Assessor(s):	Sampaio, E., Lim, B. & Peters, S.
Reviewer(s):	Solari, S.
Justification: This species is listed as Least Concern because, although it is relatively restricted distribution for the genus, however, likely to be more common than previously thought and are not likely to be declining at a rate to qualify for inclusion in any of the threat categories. They seem to be somewhat adaptable to urbanisation.

Geographic Range [top]

Range Description:

Population [top]

Population:

Known from few localities but can be locally common. The high roosting and flying behaviour of these bats makes detecting them and inferring population size using current methodologies extremely difficult (Lim et al. 1999).

Current Population Trend:

Unknown

Additional data:

♦ Population severely fragmented:	No

Habitat and Ecology [top]

Habitat and Ecology:	Ecology is little known. These bats fly high in open space, such as above rivers, streams, and lagoons, and above the forest canopy. They are attracted to concentrations of insects around high floodlights and are among the many species swooping around such lights, even in towns (Emmons and Feer 1997). They are associated with wet habitats and multistratal evergreen forest (Eisenberg 1989). Their roosts are not well known; perhaps they are found in or between the leaves of palm trees (Emmons and Feer 1997).
Systems:	Terrestrial
