We describe for the first time the vocalization of Scinax haddadorum from its type locality. We also aim to establish an acoustic diagnosis for this species in comparison with the morphologically similar Scinax rupestris, for which we also describe additional note types of its vocalization that were not previously reported. The advertisement call of S. haddadorum consists of a single type of relatively short (<200 ms on average), multipulsed note and the call dominant frequency is restricted mostly to low frequency values (ca. 1.5 kHz), whereas the advertisement call of S. rupestris consists of a single type of relatively long (>450 ms on average), multipulsed note, and the call dominant frequency may be contained within two distinct frequency bands. Advertisement calls across Scinax species exhibit distinctive patterns both in time and frequency structures that should be described in more detail in future studies, since we believe that they might be of help in the recognition and delimitation of species in this group of Neotropical treefrogs.

Abstract:We report the first record of Pseudopaludicola pocoto from Bahia state, Brazil. In addition to the new distributional record, which fill gaps in the species distribution, new data and brief comments on its advertisement call are also provided. We also provide a map of the localities reported in the literature.

The Rhinella granulosa group currently comprises 13 species that are distributed throughout South America, and Panama (Sanabria et al. 2010; Pereyra et al. 2015). Rhinella major (Müller & Hellmich) is a widely distributed species that occurs in the Chaco of Argentina e Paraguay, Brazilian and Bolivian Cerrado, as well as open environments along the Madeira, Tapajós, and Xingú rivers, reaching the mouth of the Amazon River (Narvaes & Rodrigues 2009).

Two species of Pristimantis are known to exist in the Cerrado Biome, P. dundeei and P. ventrigranulous. Here we report on new localities for P. dundeei that extend its known distribution and present new data on its call and habitat. The new data are from Santo Antônio do Leverger, Barra do Garças and Pontal do Araguaia (MT). Calls were noticeably pulsed to the human ear, with 2-12 similar notes released at a rate of 16-21/s. Calls lasted from 136 to 642 ms, with frequency peaks at 3937-4125 kHz. We found three emphasized frequency bands that were not harmonically related one each other, the second being the dominant one. Males called from a wide range of habitats, from bushes or trees, from open areas or inside forests. Our data from Barra do Garças extend the distribution of P. dundeei up to 380 km to east, which place it in close range to P. ventrigranulous. With regard to characteristics of their call and morphology, these two species cannot be distinguished by any feature. Further studies that consider their genetic distance would be decisive to an eventual synonymization of the two species. ARTICLE HISTORY

As presently recognized, Dermatonotus muelleri (Boettger, 1885) occurs throughout Argentina, Bolivia, Brazil and Paraguay (Brusquetti & Lavilla 2006); Paraguay referred as the type-locality (Frost 2013). Its advertisement call was briefly described by Nelson (1973) based on a sample from Brazil. In the present work, we redescribe its advertisement call based on a large sample from the Cerrado biome of Triângulo Mineiro region, state of Minas Gerais.
