Over the past decade, major advances have been made concerning the systematics and species diversity of Malagasy bats, largely based on specimens collected during inventories and associated morphological and molecular genetic studies. Herein we describe a new species of endemic bat from southern Madagascar, Miniopterus griffithsi sp. n., which is the sister taxa to Miniopterus gleni, a taxon described in 1995 (holotype from Sarodrano, just north of the Onilahy River in the southwest). Based on current information, M. griffithsi is found in the sub-arid bioclimatic zone, south of the Onilahy River, and M. gleni occurs in a variety of different bioclimatic zones, north of the Onilahy River to the northern portion of the island and on the near shore island of Ile Sainte Marie. The realization that M. griffithsi was a separate entity was first based on phylogeographic studies of the M. gleni complex. Comparisons using 397 bp of mitochondrial cytochrome b found a divergence of 1.2% within animals occurring across much of Madagascar north of the Onilahy River, 0.07% in those south of the Onilahy River, and 7.4% in populations separated by this river. Subsequently, morphological characters were identified that supported the specific separation of populations occurring south (M. griffithsi) and north of the Onilahy River (M. gleni), which include tragus shape, pelage coloration, and skull proportions.
