Remarks

This is a large Pipistrellus species (Table 2). Three individuals were caught at c. 950 m a.s.l. with a mist net set between two artificial ponds surrounded by coffee bushes. Another individual was caught with a harp trap in a coffee-rubber mixed plantation at an elevation of ca. 50 m a.s.l. In our samples, the species seems to exhibit sexual dimorphism in color and size. The females had reddishbrown fur and a shorter tibia (15.6 and 16.2 mm), whereas the males were grayish brown and had a slightly longer tibia (16.6 and 17.8 mm).
