Phylogenomic analysis of evolutionary relationships in Ranitomeya poison frogs (Family Dendrobatidae) using ultraconserved elements

•We present the first comprehensive genome-scale phylogeny for the Ranitomeya genus.•R. toraro and R. defleri are not sister species.•R. uakarii is paraphyletic, segregating based on geography and color pattern.•We designate R. amazonica from French Guiana and eastern Brazil as R. variabilis.•We describe two biogeographic hypotheses for Ranitomeya based on divergence times.
