Small Asian sheath-tailed bat

The small Asian sheath-tailed bat (Emballonura alecto) is a small bat of the family Emballonuridae found in Borneo, Sulawesi and the Philippines; the Mammal Diversity Database lists Brunei, Indonesia, Malaysia and the Philippines and gives its type locality as Manila on Luzon. It was described by Eydoux and Gervais in 1836 under the name Vespertilio (Nycticeus) alecto. Roosting sites have been found in caves, man-made tunnels and shallow spaces beneath rocks, overhangs and crevices. The Mammal Diversity Database places it in the Indomalayan realm and records its IUCN Red List status as Least Concern. The sources read say little about its diet or population, which remain to be documented. The Wikipedia article on the family Emballonuridae says that emballonurids feed mainly on insects and occasionally on fruit.
