A New Species of the Scinax ruber Clade (Anura, Hylidae) from the Espinhaço Range, Northeastern Brazil

A new species belonging to the Scinax ruber clade, morphologically similar to S. cabralensis and S. rupestris, is described from the Municipality of Miguel Calmon, State of Bahia, northeastern Brazil. This locality belongs to the northern portion of the Espinhaço Range known as Chapada Diamantina, a semiarid region in central Bahia State. The new species can be distinguished from all congeners of the S. ruber clade by a combination of adult (size, morphology, color pattern, and advertisement call) as well as larval (external morphology, and oral cavity) characteristics. The description of this frog adds another species, and the first of the S. ruber clade, to those that are endemic to Chapada Diamantina.
