Northern free-tailed bat
The northern free-tailed bat (Chaerephon johorensis) is a species of bat in the family Molossidae. It is found in Indonesia and Malaysia. Taxonomy and etymology
It was described as a new species in 1873 by Irish zoologist George Edward Dobson. Dobson had obtained the holotype from James Wood-Mason. Dobson initially placed it in the genus Molossus and the subgenus Nyctinomus, with a scientific name of Molossus (Nyctinomus) johorensis. Its species name "johorensis" is Latin for "belonging to Johor." Johor is a state in Malaysia; the holotype was collected there. Description
Its ears are large and round. Its tragi are small and squarish in shape. Its ears are connected to each other by a band of tissue called the interaural membrane. As a free-tailed bat, its tail extends beyond the uropatagium. Its dental formula is , for a total of 36 teeth. Conservation
It is currently listed as vulnerable by the IUCN. It meets the criteria for this designation because its population have declined by more than 30% from 2004–2014. References
