Records from Borneo Sabah : Baram district, Batu Ponggul, Baturong, Gomantong, Kinabatangan, Ma- dai, Sukau, Tabin, Tawau, Tepadong, (Ya- suma and Andau, 2000). Sarawak : Mulu NP ( Payne et al ., 2000 ). CentKal: Barito Ulu Research Area (D. Pio, unpublished data). EastKal: Kutai ( Payne et al ., 2000 ); Muara Maau: Long Iram (MZB); Bantol cave, International Timber Corporation logging concession, Liang Lusan cave ( Yasuma, 1994 ); Sungai Lesan PF (M. J. Struebig, un- published data). Comments This species was captured in abundance in harp-traps set in the forest understo- ry at Tabalar, Marang and Tintang forma- tions, and is considered common in nearly every cave system studied in Sabah and Sarawak where it roosts in large colonies, sometimes numbering over 100,000 ( Payne et al. , 2000 ). Apart from one record in Barito Ulu, the limited records of this species in cave systems in Kalimantan , suggest that large areas of karst such as Sangkulirang may be important roosting areas for this species, which is listed as Near Threatened by the IUCN (Hutson et al ., 2001).
