Geographical Variation in Morphological and Bioacoustic Traits of Pseudopaludicola mystacalis (Cope, 1887)‎ and a Reassessment of the Taxonomic Status of Pseudopaludicola serrana Toledo, 2010 (Anura : Leptodactylidae: Leiuperinae)‎

Abstract EN

Comparisons of advertisement calls of anurans can be used to determine intra- and interspecific differences or affinities.

Described from midwestern Brazil, Pseudopaludicola mystacalis is widely distributed and abundant in major open Brazilian ecosystems.

However, researchers frequently fail to determine the true taxonomic status of some of these populations and attribute them to unidentified or misidentified species.

Herein, we employ morphological and bioacoustic data to reassess the distribution range and to evaluate intraspecific variation in P.

mystacalis based on specimens from fifteen localities and seven Brazilian states.

We also reassess the distribution and taxonomic status of Pseudopaludicola serrana, herein considered as a junior synonym of P.

murundu based on morphology, bioacoustics, and molecular data.
