Geographic Range [top]

Range Description:This species is endemic to India and is known only from the villages of Katangi, Katanga and Richhai in Jabalpur district of Madhya Pradesh (Khajuria 1970). Surveys in the early 1990s in Madhya Pradesh by the Zoological Survey of India did not record this species in places other than the above (M.K. Ghosh and Tarapada Bhattacharyya pers. comm. 2007). It has been recorded from sea level to 200 m asl. The extent of occurrence is less than 5,000 km² and the area of occupancy is less than 500 km² based on the likely foraging radius of 10 km² and roost fidelity of similar sized hipposiderid species (Brosset 1966, Molur et al. 2002).

Population [top]

Population:Khajuria (1970) reported it to be uncommon and reported this species from six different roosts in three different villages in Jabalpur district of Madhya Pradesh.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is colonial, roosting in colonies of several individuals in caves both small and large and is also found beneath large granite boulders and shares its roost with other species of bats. The foraging habitat is dry tropical forest. It feeds on beetles, crickets, and other small insects (Khajuria 1970, Bates and Harrison 1997).

Threats [top]

Major Threat(s): This species is threatened by habitat loss, largely due to stone quarrying operations (C. Srinivasulu pers. comm. 10 October 2007). It might additionally be threatened by general disturbance of roosting caves.

Conservation Actions [top]

Conservation Actions: There are no direct conservation measures in place for this species. The species has not been recorded from any protected areas. Further studies are needed into the taxonomy, distribution, abundance, reproduction and ecology of this species. Populations of this species should be monitored to record changes in abundance and distribution. There is a need to protect roost sites for this species, and overall habitat maintenance, conservation and restoration are needed. The viability of establishing captive-breeding colonies for this species should be assessed. Public awareness campaigns need to be taken up to mitigate further threats to this highly restricted range species (Molur et al. 2002).
