Assessor(s): Bates, P., Bumrungsri, S., Francis, C., Csorba, G., Walston, J., Molur, S. & Srinivasulu, C.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Although this species is known mainly from isolated records from a large area, it is listed as Least Concern in view of its wide distribution, presumed large overall population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]
