Abstract
Abstract. A recent systematic revision pointed out that the name Boana polytaenia has been applied to a nonmonophyletic assemblage because populations identified as B. polytaenia from the northern Mantiqueira and southern Espinhaço mountain ranges are not closely related with the species' nominal clade. In this sense, specimens from these two biogeographic regions were recovered within two clades named Boana sp. 3 and Boana sp. 4, respectively. Here we characterized and compared external morphologies, calls, and DNA of specimens of the clade of B. polytaenia and from the two candidate species (Boana sp. 3 and Boana sp. 4). From these comparisons we herein describe a new cryptic species. Boana guarinimirim sp. nov. differs from its closely related species by the presence of a supracloacal crest, calcar appendage, and conspicuous discs on toes. Nevertheless, the new species could not be completely discriminated from its distantly related taxon B. polytaenia. We applied the new name to the clade distributed throughout the northern Mantiqueira range (Boana sp. 3), but the new name could also be applied to the clade from southern Espinhaço range (Boana sp. 4). Additional sampling efforts and new sources of evidence, such as larvae morphology and chromosomal features, should evaluate whether the lineages are conspecifics.
期刊介绍:
The Journal of Herpetology accepts manuscripts on all aspects on the biology of amphibians and reptiles including their behavior, conservation, ecology, morphology, physiology, and systematics, as well as herpetological education. We encourage authors to submit manuscripts that are data-driven and rigorous tests of hypotheses, or provide thorough descriptions of novel taxa (living or fossil). Topics may address theoretical issues in a thoughtful, quantitative way. Reviews and policy papers that provide new insight on the herpetological sciences are also welcome, but they must be more than simple literature reviews. These papers must have a central focus that propose a new argument for understanding a concept or a new approach for answering a question or solving a problem. Focus sections that combine papers on related topics are normally determined by the Editors. Publication in the Long-Term Perspectives section is by invitation only. Papers on captive breeding, new techniques or sampling methods, anecdotal or isolated natural history observations, geographic range extensions, and essays should be submitted to our sister journal, Herpetological Review.
