Remarks

This is a medium-sized Miniopterus species. All individuals were captured in or near the Gimbar 2 cave within Way Canguk Forest, except one individual from Sumber Rejo Village. The skin on the face is dark brown and the tragus is pale white to grayish brown. It can be distinguished from M. australis by the larger size and skin coloration of the face and from M. magnater by the smaller body size (Table 2) in our study area. Comparing with other known Miniopterus species on the Sunda Shelf, its forearm length falls into the range of M. pusillus and M. medius, and partially overlaps with M. fuliginosus. It has a similar body mass range to M. pusillus, overlaps partially with M. medius, and lighter than M. fuliginosus. Its tibia length overlaps partially with M. pusillus, falls into the range of M. fuliginosus, and is longer than in M. medius (Table 4). Despite its slightly larger tibia length, we tentatively assign this bat as M. pusillus based upon its forearm length and body mass. Further comparison of craniodental characters and genetic analyses are necessary to confirm the identification of this species.
