Records from Borneo Brunei : Batu Ponggul. Sabah: Goman- tong, Kinabatangan, Madai, Pulau Balem- bangan, Pulau Banggi, Pun Batu, Tabin, Tepadong (Yasuma and Andau, 2000). Sa- rawak: Mulu NP, Niah NP; Long Lama, Sungai Baram (Yasuma and Andau, 2000). WestKal: Betung Kerihun NP (Hariuchi, 1999). EastKal: Bukit Soeharto, Liang Lu- san cave ( Yasuma, 1994 ); Kutai ( Payne et al., 2000 ). Comments A large colony estimated to exceed 10,000 individuals was found distributed among several chambers of Gua Sungai at Marang and a second (> 500 individuals) found at Gua Kelelawar at Tintang. Else- where in Borneo it is found in large num- bers in most karst areas surveyed, including offshore islands in Sabah (Yasuma and Andau, 2000), although these captures in Sangkulirang represent one of few records in Kalimantan. Although the taxonomy of Miniopterus is poorly understood, M. australis is distinguished in Borneo by its small size (FA in Sangkulirang 35.9– 37.8 mm ).
