Northern free-tailed bat

The northern free-tailed bat, Mops johorensis, is a bat in the family Molossidae that is found in Indonesia and Malaysia. The Irish zoologist George Edward Dobson described it as a new species in 1873, first placing it in the genus Molossus and the subgenus Nyctinomus; the type specimen came from Johor in Malaysia, which gives the species name its meaning of belonging to Johor. It has large, rounded ears, small squarish tragi, and a band of tissue called the interaural membrane joining the two ears. Like other free-tailed bats, its tail extends beyond the membrane between the legs. It has 36 teeth. The IUCN lists it as vulnerable because its population fell by more than 30 percent between 2004 and 2014.
