The “poison frogs” (Dendrobatidae family) are a group of species widely distributed on Earth’s ecosystems. Through the analysis of morphological characters and color pattern of the best known species of Dendrobatidae and specialized software routines of phylogenetic systematics, it was inferred a phylogeny for that group aiming to find unknown phylogenetic relations. Some phylogenetic relationships are new compared with published studies as Summers and Clough (2001) and Grant et al. (2006), who used molecular basis, but others are now supported by this study. The consensus cladogram is supported by high bootstrap support values in almost all the branches. With high consistency and retention of the consensus tree (0.68 and 0.62, respectively), the methodology reinforces the potential of the species external morphology as a tool for phylogenetic inference.
