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
