Tadpole and advertisement call of Physalaemus erythros Caramaschi, Feio & Guimarães-Neto, 2003 (Amphibia, Anura, Leiuperidae)

Abstract

We describe the tadpole and the advertisement call of Physalaemus erythros Caramaschi, Feio & Guimarães-Neto, 2003 from Parque Estadual do Itacolomi, Municipality of Ouro Preto, State of Minas Gerais, Brazil. Our data are compared with the information available for Physalaemus rupestris, the only species of the Physalaemus deimaticus species group with known tadpole and advertisement calls.

Redescription of Physalaemus barrioi (Anura: Leiuperidae)

“…The advertisement call of Physalaemus barrioi differs from species of the: i) P. deimaticus (Nascimento et al, 2001;Baêta et al, 2007a) and P. signifer groups (Cardoso and Haddad, 1985;Heyer et al, 1990;Wogel et al, 2002;Haddad and Sazima, 2004;Pimenta et al, 2005;Weber et al, 2005b) by the frequency modulation and the absence of pulses; ii) P. albifrons group by the shorter duration of the call of P. biligonigerus and P. santafecinus (Barrio, 1965), and by the higher minimal, maximum, and dominant frequencies than that found in P. marmoratus (Giaretta and Menin, 2004); iii) P. cuvieri group by a lower dominant frequency and a lower number of harmonics than P. albonotatus (Barrio, 1965), by a higher number of harmonics than P. cuvieri (Cardoso, 1981), and by a longer duration of the call and lower dominant and maximum frequencies than P. erikae ; iv) P. henseli group by the absence of harmonics in P. fernandezae and P. henselii (Barrio, 1965), longer duration and higher minimum frequency than P. riograndensis (Barrio, 1965); v) P. olfersii group by shorter call duration, except P. aguirrei , from which P. barrioi differs by the higher dominant and minimum frequencies; vi) P. gracilis group by higher call duration and lower number of harmonics than P. gracilis (Barrio, 1965), presence of pulses in P. jordanensis (Bokermann, 1967), and lower number of harmonics and by having higher minimal frequency than P. evangelistai (Bokermann, 1967). In his description of the call of P. barrioi, Bokermann (1967) found 21 harmonics not detected by us.…”

“…Tadpoles of the P. henselii group have a medial vent tube (dextral in P. barrioi, the most common condition in the genus). Tadpoles of the P. olfersii species group present P-1 and P-2 of equal size (Baêta et al, 2007a(Baêta et al, , 2007b, P-3 being the shortest tooth row (in P. barrioi the posterior tooth rows are P-1.P-2.P-3). The tadpole of P. barrioi can also be distinguished from P. marmoratus, P. albifrons, P. riograndensis, and P. albonotatus by the two ventral gaps in the lower lip.…”

Head in the clouds: a new dwarf frog species of the Physalaemus signifer clade (Leptodactylidae, Leiuperinae) from the top of the Brazilian Atlantic Forest

“…For the comparisons with the known tadpoles of the Physalaemus signifer clade (sensu Lourenço et al 2015), we used the original tadpole descriptions of P. angrensis (Ruggeri et al 2011), P. atlanticus (Haddad & Sazima 2004), P. bokermanni (Cardoso & Haddad 1985), P. caete (Pombal & Madureira 1997), P. camacan (Pimenta et al 2005), P. crombiei (Ruggeri & Weber 2012), P. erythros (Baêta et al 2007), P. irroratus (Cruz et al 2007), P. maculiventris (Bokermann 1963), P. moreirae (Provete et al 2011), P. nanus (Ceron & Santana 2017), P. rupestris (Nascimento et al 2001), P. signifier (Weber & Carvalho-e-Silva 2001), P. spiniger (Haddad & Pombal 1998), and the comparative study of Ruggeri & Weber (2012).…”
