Comments

Eight individuals were captured in harp- traps set across old logging skids on the slopes of the Tabalar formation. This spe- cies is distinguished from most other Myotis by the wing membrane being attached at the side of the foot. It is known to roost in crevices and bell-holes in caves and is asso- ciated with large areas of water (Payne et al., 2000). These authors report M. hors- fieldii from most lowland areas in Sabah and Sarawak, and the SAMD regard this species as widely distributed over much of Borneo. However, apart from a further re- cord from Sungai Wain in 2005, as far as we are aware, the Tabalar records are the first report of this species occurring in Kali- mantan.
