English Black And Red Free-tailed Bat

Taxonomic Notes: This endemic species from Madagascar  was described by Goodman and Cardiff (2004). It was described in the genus Chaerephon, but was previously included on the IUCN Red List under the genus Tadarida following a proposed continental classification of the Molossidae prepared by David and Meredith Happold for the Mammals of Africa.

Lamb et al. (2011) indicate that, although morphologically similar to other Chaerephon taxa, C. jobimena is genetically more similar to Tadarida. In particular, it is closest to T. aegyptiaca, however, Tadarida is not a natural group and these two species should probably be assigned to another genus. Until the relationships are fully resolved, jobimena is treated here under Chaerephon.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2008-07-01
Assessor(s): Andriafidison, D., Cardiff, S.G., Goodman, S.M., Hutson, A.M., Jenkins, R.K.B., Kofoky, A.F., Racey, P.A., Ranivo, J., Ratrimomanarivo, F.H. & Razafimanahaka, H.J.
Reviewer(s): Hutson, A.M., Racey, P.A. & Hoffmann, M.
This species is listed as Least Concern because although it appears to be rather rare in the few areas where it is known to occur, it is widespread and its population status may not be related to the amount or state of native forest. Additional information are needed on its propensity for roosting in large colonies in synanthropic settings as this will be crucial to a better understanding of its conservation status.
Previously published Red List assessments:
2008 Least Concern (LC)

Geographic Range [top]

Range Description: This species is endemic to Madagascar where it is found from the north-west to the south-west of the island. It is known to occur in areas with dry deciduous or spiny forest from 50 to 870 m above sea level (Goodman and Cardiff 2004; Goodman et al. 2005). Although further surveys may reveal that this species is more widespread than currently known, it has yet to be recorded from some sites with extensive limestone caves, from where it would be expected based on habitat preference and distribution (Goodman and Cardiff 2004; Goodman et al. 2005; Cardiff 2006).

Population [top]

Population: The population and local abundance of this species are not known, but at Ankarana the recorded roost is 1,200 individuals (S. G. Cardiff pers. obs.). Forty individuals were recorded from a house roughly 10 km from Parc National de Namoroka (A. F. Kofoky pers. obs.).
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It is usually associated with tropical dry deciduous forest, and the spiny bush of the south-west on a karst and sandstone substrate (Goodman et al. 2005). This species roosts in caves and houses, and buildings in villages (Goodman and Cardiff 2004). In the extended network of caves at the Réserve Spéciale d’Ankarana, C. jobimena was only found in a single cave (Cardiff 2006).
Systems: Terrestrial

Threats [top]

Major Threat(s): The threats to this species are not well known, but it is probably hunted in the south of Madagascar for food.

Conservation Actions [top]

Conservation Actions: This species is known from in or near to four protected areas, but is never as common or as abundant as other sympatric molossid species (Goodman and Cardiff 2004; Goodman et al. 2005) and its conservation status should be reviewed in the future when new data are available. In particular, information on its propensity to dwell in buildings is needed.
