Geographic Range [top]

Range Description:This species is endemic to India and is presently known only from the two localities of Hanumanahalli and Theralli, in Kolar District, Karnataka State (Kock and Bhat 1994). It has not been recorded from additional nearby localities despite surveys by K.S. Sreepada (surveys from 1993 to 1997) and R. Krishnan (S. Molur pers. comm. 2008). It has been recorded from 500 to 570 m asl. The extent of occurrence is 101-5,000 km² and the area of occupancy is estimated to be less than 500 km² because of a likely foraging radius of 10 km² based on foraging ecology and roost fidelity of similar sized hipposiderid species (Brosset 1966, Molur et al. 2002).

Habitat and Ecology [top]

Habitat and Ecology:Little is known about the habitat or ecology of this species except that it roosts in granite caves in subterranean habitats and shares its roosts with other hipposiderid species such as H. ater, H. fulvus and H. speoris (Kock and Bhat 1994, Molur et al. 2002).

Threats [top]

Major Threat(s): This species is threatened by mining activities and loss of foraging habitats (Molur et al. 2002).

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. Studies in taxonomy, distribution, abundance, reproduction, ecology and population monitoring are required immediately. There is a need to identify and protect key roosting caves for this species, and general habitat maintenance, conservation and restoration is also needed. Public awareness about the endemicity and status of this species is recommended (Molur et al. 2002).
