Abstract

We describe and formally name a species of big-eared bat (genus: Micronycteris), collected from the Lesser Antillean island of Saint Vincent. The new species is distinguished from its closest relative, Micronycteris megalotis, by its large size, distinct craniodental features, and by mitochondrial DNA variation. The distribution of the new species is restricted to the island of St. Vincent, southern Lesser Antilles. Relaxed molecular clock analyses indicate the most recent common ancestor between the St. Vincent species of Micronycteris and mainland populations of M. megalotis is less than 1 million years. Rising sea levels during the late Pleistocene likely contributed to the geographic isolation and subsequent allopatric speciation of this new species. Our data reinforce previous hypotheses regarding unrecognized species diversity within the M. megalotis complex.
