Advertisement call description of two Proceratophrys species (Anura: Odontophrynidae).

The genus Proceratophrys Miranda-Ribeiro comprises 41 species distributed in South America, especially in Brazil (Nascimento et al. 2019). Proceratophrys species have been traditionally organized into four species groups based on morphology of supraocular and postocular swellings, and presence or absence of rostral appendage (Cruz Napoli 2010). However, these groupings are not supported by molecular data (Teixeira et al. 2012; Dias et al. 2013, Mângia et al. 2018).
