Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Mickleburgh, S., Hutson, A.M., Bergmans, W. & Juste, J.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Endangered because its extent of occurrence is less than 1000 km², all individuals are in a single location (the island of São Tomé), and there is continuing decline in the extent and quality of its lowland habitat.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This little known species has been recorded from two lowland localities, Praia das Conchas (3 km NW of Guadalupe) and Agua Izé, in the northern part of São Tomé Island, of São Tomé and Príncipe. Extensive surveys have not located the species elsewhere on the island.
Countries occurrence:
Sao Tomé and Principe (Sâo Tomé)

Population [top]

Population:It seems to be a very rare species that, despite considerable trapping effort, is currently only known from the type series of three specimens (J. Juste pers. comm. 2008).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species has been recorded from Praia das Conchas which is quite open and the driest point of the island (open savanna forest with baobabs), and from Agua Izé which is much more humid, and although it is now cocoa plantations it was previously forest (J. Juste pers. comm. 2008). It is unclear if the species can persist in modified habitats. The colony size is not known.

Threats [top]

Major Threat(s): The species is believed to be threatened by general habitat loss resulting from coastal development, including tourism activities, conversion of land to agricultural use and possible port construction. The species may be competing with the much more abundant species Chaerephon pumilus (J. Juste pers. comm. 2008), with further studies into this relationship needed.

Conservation Actions [top]

Conservation Actions: There appear to be no direct conservation measures in place. It is not known if the species is present in any protected areas. Further research is needed into the distribution, natural history and threats to this species.
