Miniopterus australis
Spotted 300M in Cabalyoriza Cave, Mabini, Pangasinan. Possibly a young insectivore.
Like all Miniopterus, this species has very dark brown fur that is longer over the shoulders and top of the head than elsewhere on the body; a tragus that is short and is blunt and broadest at the tip; and the tip of the longest digit on the wing folds back rather tightly against the adjacent portion of the wing (hence the English common name). Miniopterus schreibersii is larger, total length 101-112 mm, forearm 42-46 mm; M. tristis is much larger. -http://archive.fieldmuseum.org/philippine_mammals/species/SP_137.asp

M. australis confirmed by Rai Gomez (Phil. Bat Champions).
What I thought was a juvenile may possibly be an adult M. australis, which is the smallest of the three Miniopterus spp. in the Philippines.
Added photo of the targus (photo #4), which is a projection from the base of the ear...
