Here, we describe the advertisement and territorial calls of Pithecopus rusticus and determine the influence of air temperature and morphometric variables on advertisement call parameters. We recorded the vocalizations at the type-locality, in the municipality of &Aacute;gua Doce, state of Santa Catarina, southern Brazil, from September 2015 to February 2016. The advertisement call was composed of a short note, emitted sporadically, with a duration of 0.023 &plusmn; 0.002 ms (0.019&ndash;0.033 ms; n = 244). We recorded two types of territorial calls that were observed during the interaction between males. Territorial call I was composed of two notes and had a duration of 0.095 &plusmn; 0.043 ms (0.033&ndash;0.166 ms; n = 27). Territorial call II was a multipulsed note lasting 0.911 &plusmn; 0.340 ms (0.504&ndash;1.346 ms; n = 9) composed of 7&ndash;58 pulses emitted after territorial call I. Advertisement call duration was negatively related to air temperature. The duration and number of notes of the advertisement call of P. rusticus were similar to those of phylogenetically close species. Information on vocal repertoires of amphibians and factors influencing acoustic parameters are essential to understand the systematic taxonomy and evolution of groups, especially little-known species such as P. rusticus.</p>

However, variation in acoustic traits is not always correlated with genetic differences between populations (intraspecific variation); phenotypic plasticity and environmental variables may explain part of such variation. For example, local processes can affect acoustic properties in different lineages due to differences in physical structure, climatic conditions, and biotic interactions, particularly when populations are isolated. However, acoustic traits can be used to test phylogenetic hypotheses. We analyzed the advertisement calls of Dendropsophus elegans males from 18 sites and compared them with those of four closely related congeneric species, in order to test for differences between inter and intraspecific variation. We analyzed 451 calls of 45 males of these five species. Because males from distant sites were grouped together without population congruence, differences found in advertisement calls among individuals were not correlated with phylogeographical clades. Phylogenetic and cluster analyses of the D. elegans clades and those of closely related species grouped all five species into the same topology, as reported by previous molecular and morphological phylogenies. However, the topology of the D. elegans phylogeographical clades did not match the topology previously reported. Acoustic communication in D. elegans seems to be conserved among populations, and the phylogeographical history of the species does not explain the variation among lineages in call properties, despite some congruent phylogenetic signals evident at the species level. Based on molecular clocks retrieved from the literature, it seems that more than 6.5 million years of divergence (late Miocene) are necessary to allow significant changes to occur in the acoustic properties of these treefrog calls, making it possible to recover their phylogenetic history only based on acoustic evidence.</p>
