Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hutson, A.M. & Bergmans, W.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Vulnerable because it is known from fewer than five locations, and it is plausible that it will decline as a result of disturbance to its cave roosting sites.

Geographic Range [top]

Range Description:This species occurs on the islands of Mauritius and Rèunion. There is a single doubtful record for Madagascar (Peterson et al. 1995), two old records for South Africa (both near Durban in 1833 and undated), and an old record from taken between the district of Shoa and Lake Rudolph in southern Ethiopia (Hayman and Hill 1971; Skinner and Chimimba 2005). It is now considered most likely that specimens taken outside of the Mascarene Islands were vagrants, and that the species should be considered endemic to Mauritius and Rèunion (Skinner and Chimimba 2005; Goodman 2007).
Countries occurrence:
Mauritius; Réunion
