About Mormopterus
Mormopterus is a genus of molossid microchiropterans, small flying mammals referred to as free-tailed bats. The genus has been the subject of several revisions, and the diversity of taxa centred on Australia were separated to a new genus Ozimops, and two monotypic genera, Setirostris and Micronomus. The species of Mormopterus, in this stricter sense, are only found in areas outside of Australia and West Papua.
