Data from: Phylogeny and biogeography of Poecilia (Cyprinodontiformes: Poeciliinae) across Central and South America based on mitochondrial and nuclear DNA markers

Poeciliids are a diverse group of small Neotropical fishes, and despite
considerable research attention as models in ecology and evolutionary
biology, our understanding of their biogeographic and phylogenetic
relationships is still limited. We investigated the phylogenetic
relationships of South and Central American Poecilia, by examining 2395
base pairs of mitochondrial DNA (ATPase 8/6, COI) and nuclear DNA (S7) for
18 species across six subgenera. Fifty-eight novel sequences were acquired
from newly collected specimens and 20 sequences were obtained from
previously published material. Analyses of concatenated and partitioned
mitochondrial DNA and nuclear DNA sets resulted in a well-supported
phylogeny that resolved several monophyletic groups corresponding to
previously hypothesized subgenera and species complexes.
