An acoustic and morphometric evaluation of the geographic distribution of Phyllomedusa burmeisteri (Anura: Phyllomedusidae), with comments on P. bahiana. A recent study, based on phylogenetic and phylogeographic multilocus approaches, detected two evolutionary units (BUR and BUR-RJ) within the range of P. burmeisteri. BUR has a wide distribution, whereas BUR-RJ is restricted to a small area coincident with the Serra do Mar mountain range in the Brazilian state of Rio de Janeiro. We evaluate if acoustic and morphometric data support these two major clades within P. burmeisteri that were proposed using molecular evidence. We also provide for the frst time detailed morphometric data for adult males of P. burmeisteri (including topotypes) and the holotype of P. bahiana, and we revisit the comparative acoustic diagnosis between P. burmeisteri and P. bahiana. We were unable to distinguish BUR and BUR-RJ evolutionary units based on morphometric, acoustic or any other feature of external morphology or coloration. Given the high levels of similarity in morphometric and acoustic traits between P. burmeisteri and P. bahiana, these features appear not to be informative in the differentiation of the two sister species.

Molecular Characters

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.
