discussion
Remarks This is a brown, medium-sized Myotis species (FA = 38.1 – 38.8 mm). One bat was captured flying low over rivers of 10 m in width, surrounded by coffee plantations, and at an elevation less than 50 m a. s. l. An adult male was collected by previous researchers from Gimbar 2 cave in Way Canguk Forest (MZB 35805). The wing membrane narrows markedly near the ankle and forms a prolonged strip inserting to the metatarsus, which has been seen in M. simus from Paraguay (López-González et al., 2001) and Myotis sp. 1 from Taiwan (Huang et al., 2008). P 3 partially intrudes from the toothrow, and P 2 and P 4 are completely separated. The crown area of P 3 is around one-third that of P 2 and the crown area of P 3 around half that of P 2. Comparing with known species on the Sunda Shelf, the bat is similar to M. adversus, M. hasseltii, and M. horsfieldii in body size and habitat use (Kingston et al., 2006). However, the wing membranes attach directly to the ankle in M. adversus and M. hasseltii, and directly to the metatarsus in M. horsfieldii (Bates and Harrison, 1997; Bates et al., 2005). Moreover, P 2 is completely in line with the toothrow in M. adversus and displaced inward in M. hasseltii (Yasuma et al., 2003; Francis, 2008). Based on the traits compared, we are not able to assign it to any known species. Genetic analyses and comparisons with more species across a greater geographic range are necessary for species identification.
