Bioacoustics of Odontophrynidae

Proceratophrys sp. ( cf. ararype ). Several species of the genus Proceratophrys Miranda-Ribeiro, 1920 have been recently described by integrative approaches, using morphological, molecular, and acoustic data ( Teixeira et al . 2012 ; Brandão et al . 2013 ; Dias et al . 2013 ; Mângia et al . 2014 , 2018 , 2022 ). Our molecular data recovered the Proceratophrys population from Caseara closely related to P. ararype Mângia, Koroiva, Nunes, Roberto, Ávila, Sant’Anna, Santana, and Garda, 2018 , with 0.8% of genetic distance (Supplementary material, Table S5). Regarding the advertisement call, the parameters of Proceratophrys sp. ( cf. ararype ) overlap with those presented by Mângia et al . (2018) for P. ararype ( Table S3 ). In contrast, we found some differences between Caseara and Chapada do Araripe populations, such as the female size (SVL 37.9–42.6 mm and 51.3–57.0 mm, respectively), the proportion of the head length in relation to SVL (40% and 46%, respectively), head largest than wider, and the snout shape in dorsal and ventral views (triangular in Caseara individuals, and rounded in individuals from Araripe) ( Table S2 ). There is a sampling gap between the type locality of P. ararype and Caseara (~ 1200 km ), suggesting that we might be evaluating extremes of the species distribution. However, further investigations are needed to clarify this issue. For these reasons, we consider the individuals recorded in the present study as Proceratophrys sp. ( cf. ararype ).
