RESUMO
The genus Proceratophrys Miranda-Ribeiro, 1920, frogs from the family Odontophrynidae Lynch, currently contains 41 nominal species with poorly resolved phylogenetic relationships (Frost 2019; Mângia et al. 2018). Molecular data from 15 and 18 Proceratophrys species support the monophyletic hypothesis of the genus (Teixeira-Jr et al. 2012; Dias et al. 2013; respectively) but do not fully resolve the phylogenetic relationship among the species. Currently, there are advertisement call parameters provided for 31 species of Proceratophrys in the literature (Ferreira et al. 2016; Andrade et al. 2018; Mângia et al. 2018; Nascimento et al. 2019). The Proceratophrys advertisement call is composed of pulsed notes, amplitude modulation, short to medium duration calls (0.05-4 s) and only one note in almost all species (see Nascimento et al. 2019 for details). Considering the importance of bioacoustics for taxonomy (Köhler et al. 2017), further descriptions of advertisement calls for the genus could also improve our understanding of the species' relationships.

Proceratophrys Miranda-Ribeiro, 1920 currently comprises 40 species (Frost 2017) of which 15 are allocated into the Proceratophrys cristiceps species group (sensu Brandão et al. 2013). The species in this group are characterized by the absence of postocular swellings and, except for P. concavitympanum, are found in seasonally open habitats in Brazilian Cerrado and Caatinga morphoclimatic domains (Giaretta et al. 2000; Ávila et al. 2012; Teixeira Jr. et al. 2012; Brandão et al. 2013). Information on advertisement calls is available for 11 species of the group (Eterovick Sazima 1998; Nunes Juncá 2006; Brasileiro et al. 2008; Santana et al. 2010; Ávila et al. 2012; Martins Giaretta 2011; 2012; 2013; Ferreira et al. 2016). Proceratophrys branti Brandão, Carmaschi, Vaz-Silva Campos, 2013 has been recently described and allocated in the P. cristiceps species group. The species occurs in open areas in the north-central portion of the Brazilian Cerrado, in the states of Goiás, Minas Gerais and Tocantins (Brandão et al. 2013). Herein we describe for the first time its advertisement call, based on recordings made in an area of Cerrado biome in the state of Tocantins.

Proceratophrys dibernardoi Brandão, Caramaschi, Vaz-Silva & Campos 2013 has recently been described and allocated into the P. cristiceps species group, but no information about its advertisement calls has been provided (Brandão et al. 2013). Here, we describe for the first time the advertisement calls of P. dibernardoi based on specimens from Central Brazil. We also expand P. dibernardoi´s geographic distribution by reporting a new population in the State of Mato Grosso do Sul, Brazil, constituting the westernmost record for this species, and extending its known range approximately 330 km westward of the municipality of Aporé, State of Goiás (P. dibernardoi´s former westernmost record).
