Identification of the taxonomic status of Scinax nebulosus and Scinax constrictus (Scinaxinae, Anura) based on molecular markers

Abstract The validation of many anuran species is based on a strictly descriptive, morphological analysis small number specimens with limited geographic distribution. Scinax Wagler, 1830 genus controversial group doubtful taxa and taxonomic uncertainties, due high cryptic species. One example the pair constrictus nebulosus, which share similar morphology. restricted to Brazilian Cerrado savanna, while S. nebulosus widely distributed throughout northern South America. Despite species, discriminations only traits quite difficult conservative morphology some groups. In this context, present study uses mitochondrial nuclear genes provide more consistent diagnosis test validity as distinct from well evaluate position these within genus. topologies obtained herein uphold monophyletic status all molecular markers assessed in study, analytical approaches, levels statistical support.
