Supplementary material from: Deep divergences among inconspicuous clades of Epipedobates poison frogs
<p>Poison frogs (<em>Dendrobatidae</em>) are famous for their aposematic species, having a combination of diverse color patterns and defensive skin toxins, yet most species in this family are inconspicuously colored and considered non-aposematic. <em>Epipedobates</em> is among the youngest genus-level clades of <em>Dendrobatidae </em>that includes both aposematic and inconspicuous species. Using Sanger-sequenced mitochondrial and nuclear markers, we demonstrate deep genetic divergences among inconspicuous species of <em>Epipedobates</em> but relatively shallow genetic divergences among conspicuous species. Our phylogenetic analysis includes broad geographic sampling of the inconspicuous lineages typically identified as <em>E. boulengeri </em>and <em>E. espinosai</em>, which reveals two putative new species, one in west-central Colombia (<em>E.</em> sp. 1) and the other in north-central Ecuador (<em>E. </em>aff. <em>espinosai</em>). We conclude that <em>E. darwinwallacei</em> is a junior subjective synonym of <em>E. espinosai</em>. We also clarify the geographic distributions of inconspicuous <em>Epipedobates </em>species including the widespread <em>E. boulengeri.</em> We provide a qualitative assessment of the phenotypic diversity in each nominal species, with a focus on the color and pattern of inconspicuous species. We conclude that <em>Epipedobates</em> contains eight known valid species, six of which are inconspicuous. A relaxed molecular clock analysis suggests that the most recent common ancestor of <em>Epipedobates</em> is ~11.1 million years old, which nearly doubles previous estimates. Last, genetic information points to a center of species diversity in the Chocó at the southwestern border of Colombia with Ecuador.</p>
