The tadpole of Leptodactylus barrioi from the Atlantic Forest of southeastern Brazil (Amphibia: Anura: Leptodactylidae)

摘要

Leptodactylus is a genus of Neotropical frogs in the family Leptodactylidae, which has 83 species (Frost 2021). With the exception of L. hylodes (Reinhardt & Lütken) and L. lauramiriamae Heyer & Crombie, the remaining species are distributed in four major clades, based on molecular analysis, adult and larval morphology and behavioral data: L. fuscus, L. latrans, L. melanonotus, and L. pentadactylus groups (de Sá et al. 2014; Silva et al. 2020). Allocated in the L. fuscus clade, the L. mystaceus complex is composed of eight species: L. didymus Heyer, García-Lopez & Cardoso, L. elenae Heyer, L. mystaceus (Spix), L. notoaktites Heyer, L. spixi Heyer, L. kilombo Alves da Silva, Magalh?es, Thomassen, Leite, Garda, Brand?o, Haddad, Giaretta & Carvalho, L. watu Alves da Silva, Magalh?es, Thomassen, Leite, Garda, Brand?o, Haddad, Giaretta & Carvalho, and L. barrioi Alves da Silva, Magalh?es, Thomassen, Leite, Garda, Brand?o, Haddad, Giaretta & Carvalho. The species of this complex are widely distributed in forests and open formations of South America east of the Andes and are almost indistinguishable morphologically (Silva et al. 2020). Among the species in this complex, L. barrioi occurs in the Atlantic Forest of southeastern Brazil, in the states of Minas Gerais and Espírito Santo (Silva et al. 2020; Frost 2021). This frog was recently described based on acoustic and molecular characters (Silva et al. 2020), but the characteristics of its tadpoles are unknown. Thus, here we describe the tadpole of L. barrioi, and compare it to the species of the L. mystaceus complex.
