Year Published: 2008
Date Assessed: 2008-06-30

Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species is widely distributed in Southeast Asia, with additional records from South Asia and China. In Southeast Asia, it has been recorded from southern Myanmar and Thailand, into Peninsular Malaysia, and from here into Indonesia (including the Mentawi Islands [Nias], Sumatra, Bangka, Billiton, Java and Banta), ranging to the island of Borneo (Brunei, Indonesia and Malaysia). In South Asia, it is presently known from Assam and West Bengal in India, recorded up to an elevation of 1,800 m asl (Molur et al. 2002). In China, it is known only from a single specimen recorded from Guizhou (Jinsha) (Wang 2002; Smith and Xie 2008).

Population [top]

Population:In Southeast Asia, this species is generally considered to be common in intact forest habitats. It is considered to be uncommon on the island of Sumatra (Indonesia). The abundance, population size and trends for this species in South Asia are not known (Molur et al. 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In Southeast Asia, it has been recorded from primary and secondary tropical moist forest. It is generally considered a lowland species on Borneo and elsewhere in the region. Animals roost singly under leaves or palm leaves in the forest understory, and are believed to breed once a year. In South Asia, little is known about the habitat or ecology of this species except that it is found in dense evergreen forests (Molur et al. 2002).

Threats [top]

Major Threat(s): This species is threatened over much of its range by deforestation, generally resulting from logging operations and the conversion of land to agricultural use. In South Asia, the development of tourism related activities is also considered to be a major threat (Molur et al. 2002).

Conservation Actions [top]

Conservation Actions: It has been recorded from a number of protected areas in Southeast Asia. In South Asia, there are no direct conservation measures in place for this species. Survey, ecological and population monitoring are recommended (Molur et al. 2002).
