“…Paraíba (PB). Their data are similar to those of São-Pedro et al (2011) but are significantly different from ours in dominant frequency (mean 2949 Hz; t = -3.155, df = 13, p = 0.008), but not in duration (0.67-6.80 vs. 3.7-9.6 ms). The slight differences in SVL between our sample and theirs may in part account for the lower dominant frequency we found because spectral traits are under morphological constraints, with smaller frogs producing calls with higher frequencies (Gerhardt and Huber 2002).…”

“…Pereyra et al (2015) provided a molecular phylogeny and discussed hybridization and introgression in this clade. So far, the advertisement calls of 12 species of the R. granulosa group have been described: R. azarai (Gallardo, 1965), Rhinella beebei (Gallardo, 1965), R. bergi (Céspedez, 2000), R. centralis Narvaes andRodrigues, 2009, R. dorbignyi (Duméril andBibron, 1841), R. fernandezae (Gallardo, 1957), R. granulosa (Spix, 1824), R. humboldti (Gallardo, 1965), R. major (Müller and Hellmich, 1936), R. mirandaribeiroi (Gallardo, 1965), R. pygmaea (Myers and Carvalho, 1952), and R. merianae (Gallardo, 1965) (Zweifel 1965, Köhler et al 1997, Salas et al 1998, Guerra et al 2011, São-Pedro et al 2011, Morais et al 2012, Torres-Suárez and Vargas-Salinas 2013, Carvalho et al 2013, Protázio et al 2015, Bernardes et al 2015, Murphy et al 2017. Calls are unknown for R. nattereri (Bokermann, 1967) and R. bernardoi (Sanabria, Quiroga, Arias, and Cortez, 2010).…”

“…Rhinella granulosa was described from the Brazilian state of Bahia and is thought to have a broad distribution across northeast Brazil (states of Bahia, Sergipe, Alagoas, Pernambuco, Paraíba, Rio Grande do Norte, Ceará, and Piauí) and northern states of southeastern Brazil (Minas Gerais and Espírito Santo) (Narvaes and Rodrigues 2009). Its call is known from specimens from Rio Grande do Norte (São-Pedro et al 2011) and Paraíba (Protázio et al 2015). Rhinella merianae was described from Essequibo River, Guiana and is known to occur in Venezuela, French Guiana, Suriname, and along the Solimões, Negro and Branco Rivers in the Brazilian states of Amazonas and Roraima (Narvaes and Rodrigues 2009).…”

The advertisement call of two species of the Rhinella granulosa group (Anura: Bufonidae). The group of Rhinella granulosa presently harbors 14 species distributed in Central and South America. The advertisement calls of 12 species have been described. Herein, we provide data on the calls of R. granulosa and R. merianae recorded in populations far from locations of previous call descriptions, and we discuss possible causes of differences found. We used recordings of R. granulosa from the interior of Bahia State and recordings of R. merianae from Roraima. For both, calls consist of a long-lasting trill of four-pulsed notes. Rhinella granulosa calls last 3.7–9.6 s, have 121–283 notes, each lasting 19–25 ms released at a rate of 29.2–34.7/s, and with dominant frequency peaking between 2472–2809 Hz. Rhinella merianae calls last 4.0–7.1, have 153–217 notes, each lasting 17–20 ms, released at a rate of 37.7–39.5/s, and with dominant frequency peaking between 2959–3189 Hz. Both species are distinguished from most other species of the R. granulosa species group by the combination of pulse number and dominant frequency. Our data on R. granulosa differed (p < 0.05) in call duration and/or in dominant frequency from specimens from Natal (Rio Grande do Norte state) and Cabaceiras (Paraíba state). Our data on R. merianae appear to differ in dominant frequency from the only call (a single male) known from the Amazon River bank. The differences we found between our data and published call data suggest that further study of calls of additional populations of these species is warranted.

Despite important advances in understanding phylogenetic relationships among anurans (Frost et al. 2006; Pyron & Wiens, 2011), many uncertainties persist regarding phylogenetic affinities and taxonomic limits. The male advertisement call offers numerous opportunities to find diagnostic characters and is therefore useful for anuran species delimitation (Gerhardt & Huber, 2002; Grant et al. 2006). Thirteen species are recognized within the Rhinella granulosa group (Narvaes & Rodrigues, 2009; Sanabria et al. 2010) although it is possible that R. dorbignyi and R. fernandezae being conspecifics (Guerra et al. 2011, page 36). The advertisement call has been described for nine species of the granulosa group: Rhinella granulosa, R. bergi, R. major, R. azarai, R. fernandezae, R. dorbignyi, R. merianae, R. centralis and R. pygmaea (Köhler et al. 1997; Guerra et al. 2011; São-Pedro et al. 2011; Ribeiro de Carvalho et al. 2013). Some information regarding call features are available for R. humboldti from populations of Guyana (Lescure & Marty, 2000); however, there are no associated data of male body size, sample size, and call traits such as pulse number per notes, note duration, etc. Here we provide a formal description of the advertisement call of R. humboldti using call recordings obtained in a population in Colombia, South America.
