“…4 (118-255) 197.0 ± 6.9 species with described calls (unknown calls: P. ceratophyes, P. llanera, and P. pusilla). This non-pulsed call structure distinguishes P. giarettai from the pulsed calls of P. ameghini (Pansonato et al, 2013), P. atragula (Pansonato et al, 2014a), P. boliviana (Duré et al, 2004), P. falcipes (Haddad & Cardoso, 1987), P. mineira (Pereira & Nascimento, 2004), P. murundu (Toledo et al, 2010), P. mystacalis (Pansonato et al, 2013), P. saltica (Pansonato et al, 2013), and P. ternetzi (Cardozo & Toledo, 2013). Regarding Pseudo-paludicola species with non-pulsed structure (P. canga, P. facureae, P. hyleaustralis, and P. parnaiba), P. giarettai can easily be distinguished from all four species by its distinctive long-lasting (combined value range: 101-260 ms; Table 3) whistling call with a remarkable ascendant frequency modulation, and emitted in an intermittent calling pattern, whereas calls of all four species are emitted in a trilled calling pattern (welldefined series of non-pulsed notes) with short-lasting notes (maximum note duration: 50 ms; see Table 2 in Pansonato et al, 2012), having no or slight frequency modulation (Giaretta & Kokubum, 2003;Pansonato et al, 2012;Andrade & Carvalho, 2013;Roberto et al, 2013).…”
