Molecular systematics of the family Mormoopidae (Chiroptera) based on cytochrome b and recombination activating gene 2 sequences

Abstract

We examined 1140 bp of the mitochondrial cytochrome b gene and 1398 bp of the nuclear RAG2 gene to investigate the systematics of the eight species of bats within the family Mormoopidae. It was concluded that within the genus Pteronotus there were four valid subgenera: Phyllodia, Chilonycteris, Pteronotus, and an undescribed subgenus. Within Pteronotus, P. parnellii either was part of an unresolved tetratomy with the other three subgenera (cytochrome b data) or was basal (RAG2 and combined data). For three species, P. gymnonotus, P. macleayii, and P. quadridens, our sample revealed little geographic variation. In P. davyi and P. parnellii, the magnitude of genetic distance suggests the possibility of two biological species existing within the currently recognized taxa. Within P. personatus, there was substantial geographic variation partitioned in a step-like fashion among our specimens. Neither of the species within the genus Mormoops showed the deep distance nodes present in P. davyi, P. parnellii, and P. personatus. Cytochrome b and RAG2 data indicated that M. megalophylla evolved recently from its common ancestor. Although there was considerable agreement among the branching patterns for the nuclear and mitochondrial genes, both genes failed to provide robust data concerning the evolutionary relationships among the subgenera.
