Pio, unpublished data). EastKal: Bantol cave, Gunung Kom- beng ( Yasuma, 1994 ). Comments Individuals were captured in harp-traps set in the forest at Baai, Marang and Tintang formations. It was also captured in Gua Kelelawar at the Tintang formation. Its dis- tribution is limited to scattered localities in Sabah , Sarawak and Brunei and Peninsular Malaysia . Records from Sangkulirang are amongst only three for Kalimantan . It is known to roost in caves, rocky outcrops and hollow trees and to forage in little-disturbed forest ( Payne et al. , 2000 ). Our captures in the burnt vegetation around Baai suggest that it may also utilise secondary forests if roost resources are still available. Hipposideros galeritus Cantor, 1846
