Comments

Three individuals were captured in harp- traps set across an old logging skid on the lower slopes of the Tabalar formation. Previously this species was only known from scattered localities in Sabah, Brunei, Sarawak and West Kalimantan. Recent sur- veys have confirmed its presence in more southern localities in Central and East Kalimantan, and together with this study, extend the known SAMD distribution southwards by 400 km. It is considered primarily a for- est species and is known to roost in small groups in palm crowns, epiphytic ferns, small cavities and arboreal ant and termite nests (Kingston et al., 2006). Balionycteris maculata is therefore likely to be more widespread in Borneo than was previously thought, but probably confined to forested areas.
