Cyprinodontiforms are a major group of freshwater fishes. Two families of live-bearing cyprinodontiform fishes are the Goodeidae and the Poeciliidae. The family Goodeidae is a distinct North American lineage of freshwater fishes and is comprised of two monophyletic subfamilies (Empetrichthyinae and Goodeinae). Empetrichthyinae contains all egg-laying species and Goodeinae contains all viviparous species. The Goodeinae is recognized as a monophyletic group based on the presence of unique morphological traits associated with internal fertilization and viviparity. The classification of goodeids has been based largely on variation of reproductive and trophic characters. A molecular phylogenetic hypothesis is presented based on the cladistic analysis of mtDNA (portions of the 16s rRNA, control region, cytochrome b genes, and NADH dehydrogenase subunit 2) and nDNA (a portion of the tyrosine kinase X-src gene) of representative goodeid fishes. The comparative method based on the molecular phylogeny was used to reconstruct the evolution of key characters traditionally used in the classification of the group such as trophotaeniae, karyotypes, and tooth and jaw structures. The phylogeny agrees with some but not all conclusions from earlier studies regarding phylogenetic relationships and reproductive and trophic character evolution. Members of the subfamily Poeciliinae (Family Poeciliidae) exhibit extensive behavioral and morphological variation which when coupled with relative ease of maintenance and short generation times make them popular with both researchers and aquarists alike. Although much work regarding these fishes has been conducted in the past, most has been based on morphological and/or behavioral data resulting in implied inter- and intra-generic relationships. In systematic studies where molecular data were used, either relatively few taxa were incorporated, or the analyses were restricted to intra-generic relationships. In this study a portion of the cytochrome b gene and control region of the mtDNA genome were sequenced and analyzed both independently and combined using maximum parsimony and maximum likelihood analyses. Some aspects of the phylogenetic relationships obtained are consistent with work performed previously while others imply that a taxonomic re-evaluation of portions of the subfamily Poeciliinae is in order.
