Grandidier's free-tailed bat

Grandidier's free-tailed bat (Mops leucogaster) is a species of bat in the family Molossidae that is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and dry savanna. It has at times been considered synonymous with the little free-tailed bat. The species figures in a classical ring species hypothesis, in which two populations connected by a geographic ring of interbreeding populations do not interbreed with each other despite living in the same region: after migrating to the Comoros, Grandidier's free-tailed bat and C. pusillius became sympatric, and there is evidence of isolation between the two populations that further restricts gene flow.
