Distribution and Ecological Notes Hipposideros ridleyi is currently known from peninsular Malaysia, Singapore, Bor- neo (Sabah and Sarawak) (Simmons, 2005). This is the first confirmed record from Thailand. The voucher specimen from Thailand was captured together with a pregnant female (forearm length of 50.2 mm) in a harp trap set along a nature trail in Ba- la Forest. The local area includes many streams, which join together and become a small peat swamp (2 ha in size). Much of the ground layer is densely covered with rattans and palms. The general habitat is pristine lowland evergreen forest at the elevation of 100 m a. s. l. and the topography is essentially flat. In peninsular Malaysia, a number of specimens was also collected from peat swamp forest and along trails in lowland dipterocarp forest (Zubaid et al., 1986). This habitat type is currently threat- ened throughout Southeast Asia. In Thai- land, breeding occurs as early as late Febru- ary. Females were lactating between April and May (Kemper, 1988) and July in Bor- neo (Francis et al., 1999 b). Medway (1969) suggested it may roost in caves, although there is no evidence to support this sugges- tion. It was found roosting in road culverts in peninsular Malaysia (Gould, 1978). There are apparently no caves in the vicini- ty of the area of collection in Thailand.
