Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017

Assessor(s): Monadjem, A., Razafimanahaka, J., Ranivo, J., Kofoky, A., Hutson, A.M., Cardiff, S.G., Andriafidison, D., Goodman, S., Jenkins, R.K.B., Racey, P.A. & Ratrimomanarivo, F.H.
Reviewer(s): Piraccini, R.
Listed as Least Concern as although the species is not thought to be abundant and has not often been recorded, the available information indicates that the species is widespread across Madagascar occurring in a wide variety of habitats, including in human habitations. While the threats affecting the species are imperfectly known, there is no reason to expect that the species is currently undergoing a decline that would warrant listing in a threatened category.

Geographic Range [top]

Range Description:This species is endemic to the island of Madagascar, where it is broadly distributed from the coast to the highland plateau up to 1,400 m in Tsinjoarivo (Goodman et al. 2005). This species is rarely recorded, but as more surveys are conducted it is likely that this species will be found to have a wider distribution.

Population [top]

Population:A number of bat surveys have failed to locate this species (Goodman et al. 2005; Robinson et al. 2006; Rakotoarivelo and Randrianandriananina 2007) and it appears not to be locally abundant.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:There is very little available information on the natural history of this species. It appears to be associated with a remarkable variety of tropical forest types and has been recorded at various levels of human perturbation. It is known to roost in small colonies houses and other buildings (Ratrimomanarivo and Goodman 2005).
Generation Length (years):5.62

Threats [top]

Major Threat(s): The major threats to this species are not well known. This species uses forest habitat, but it also occurs outside of forested areas. There is one reported occurrence of this species being hunted by food by local people, but there is no evidence that this constitutes a major threat (Goodman et al. 2008).

Conservation Actions [top]

Conservation Actions: This species is known from a number of protected areas across Madagascar and does not appear to require specific conservation measures but, like many other Malagasy bats that are not considered to be threatened, there is a lack of basic natural history data.
