Next generation sequencing data in the phylogenetic relationships of the genus Molossus (Chiroptera, Molossidae)

The mastiff bat Molossus is a broadly distributed genus within the family Molossidae. Molossus includes groups of species that are either morphologically or genetically very similar, rendering the taxonomy of this genus confusing and unstable. In this paper, we provide inferred phylogenetic relationships of Molossus based on the genotype by sequencing approach from 189 specimens of three species of New World mastiff bats (Molossus, Promops, and Eumops). We also present data on divergent tree topologies produced by alignments using de novo and reference genome approaches and distinct phylogenetic methods (maximum likelihood and coalescent approaches). These data provide the first highly resolved phylogenetic tree for Molossus, not recovered by previous studies using Sanger sequencing. Our dataset brings new insights on relationships among species and show how different approaches might affect phylogenetic resolution and topologies.
