Myotis sp. 2

New records

Lampung Province: Pemerihan Village, Way Canguk Forest.

New material

One individual was collected as a voucher specimen. Lampung Province: Pemerihan Village, 1♀ (MZB 35804).

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.
