Here, we present the first comprehensive Accepted 17 April 2015 phylogenetic analysis of Brachyrhaphis by using four molecular markers (3 mtDNA, 1 nucDNA) to infer Available online 24 April 2015 relationships among species in this genus. We tested the validity of this genus as a monophyletic group using extensive outgroup sampling based on recent phylogenetic hypotheses of Poeciliidae. We also Keywo
