WestKal: Betung Kerihun NP (Hariuchi, 1999); EastKal: Bukit Soe- harto, Liang Lusan cave ( Yasuma, 1994 ); Kutai NP ( Payne et al ., 2000 ). South- Kal: Upper Sungai Tengah ( Payne et al ., 2000 ). Comments Four male individuals were captured in mist-nets set next to flowering banana trees ( Musa spp.) at the Baai camp site. This species forms large cave colonies in karst areas, and in Borneo is known from scattered localities in most states, although the SAMD recognises a distribution limited to parts of Central and East Kalimantan , excluding Sangkulirang. Although we did not record this species in our cave surveys it is likely that further research will do so. Eonycteris spelaea was distinguished from E. major by its smaller size (FA 63.1–67.3 mm, cf. E. major 71–80 mm — Payne et al ., 2000 ).
