More research on distribution, abundance, basic ecology and threats is urgently required.	This bat is poorly known. Caught in a mist net set across a stream through tall evergreen forest (Reid 1997). Probably its natural history is similar to other species of Lasiurus . It is assumed to be an aerial insectivore of uncluttered space on the basis of its morphology.	Threats to this species are unknown.	The species is extremely rare; known only from a few specimens, one from each known locality (Reid 1997, Gardner 2008). As an aerial insectivore this species is difficult to capture using current survey methodologies and so may be more abundant than currently thought.	Unknown	The species is known only from a few localities. It occurs in extreme southeastern Panama, but the extent of its range into northwestern Colombia is unknown; also occurs in French Guiana, northern and southern Brazil (Eisenberg 1989, Simmons 2005).
