Geoffroy, 1810) Geoffroy’s Rousette bat New material 1♀ ( MZB M26836 ). Records from Borneo Brunei : Tasek Merimbun ( Payne et al. , 2000 ). Sabah: Madai, Pulau Balembangan, Sukau, Tawau ( Payne et al. , 2000 ); Pulau Banggi, Pulau Malawali, Semporna, Sepi- lok (Yasuma and Andau, 2000). Sarawak : Bintulu, Niah NP, Sungai Baram ( Payne et al. , 2000 ); Bau limestone formations (Mohd-Azlan et al ., 2005). WestKal: Gu- nung Niut NR ( Colijn, 2005 ); Sungai Lan- dak (RMNH); Perbuah (Yasuma and Andau, 2000). Comments A single individual female was captured in a mist-net set over a stream at the Marang formation and collected as a voucher specimen. Unfortunately, the skull of this speci- men has since been mislaid in MZB, so we are unable to relate to comparative mate- rial. R. amplexicaudatus primarily roosts in caves (Kingston et al ., 2006) and so it is like- ly that further surveys of caves at this site will record this species. In Borneo it is known from scattered localities in Sabah , Sarawak , Brunei and West Kalimantan. This capture is the first record for East Kalimantan.
