Remarks

This was the smallest Kerivoula in our study area (FA = 27.7–30.0 mm; Wt: 2.3–3.3 g). All individuals were caught with harp traps between 50–572 m a.s.l., in forest except one, which was trapped in the understory of a mixed coffee plantation. It is a light reddish-brown bat with semi-translucent wing membranes. Body size is smaller than other Kerivoula species in the study area. The bats are externally similar to K. minuta and K. intermedia , two small species coexisting in some forests of Borneo and Peninsular Malaysia ( Kingston et al., 2003; Struebig et al., 2010). These two Kerivoula species are almost morphologically identical but differ in body mass (2.0–3.0 g for K. minuta and 3.1–3.5 g for K. intermedia ) and cranial measures ( Khan et al., 2010). Based on the measures of body mass, all our captures can be assigned to K. minuta , except one individual with a BM of 3.3 g, which falls into the range of K. intermedia . A detailed study of cranial traits of our sample collected also confirms the presence of K. minuta in our study area (B. Douangboubpha, personal communication). This is the first time the species has been recorded for Sumatra.
