Abstract
Scinax comprises more than 120 species which are split in two clades, the S. ruber and the S. catharinae clades. A few species within the S. catharinae clade occur in gallery forests of the Brazilian Cerrado. We here extend the distribution of S. centralis southwards based on new populations sampled in the banks of the Rio Paranaíba, in the borders of Minas Gerais (MG) and Goiás (GO) states, southeastern Brazil. We also provide further data on the species vocalization. Variation was seen among our population and topotypes regarding SVL and call dominant frequency, both likely representing a clinal variation. Our new population of S. centralis represents the first record of the species for the state of Minas Gerais.
Highlights
Scinax Wagler, 1830 is one of the most speciose genus of treefrogs of the Neotropics and it encompasses more than 120 species (Frost, 2021; Segalla et al, 2021)

Most species of the S. catharinae clade occur in coastal forest environments, while a few occur in phytophysiognomies of the Brazilian Cerrado biome, such as S. canastrensis (Cardoso & Haddad, 1982), S. centralis Pombal & Bastos, 1996, S. goya (Andrade et al, 2018), S. machadoi (Bokermann & Sazima, 1973), S. pombali Lourenço, Carvalho, Baêta, Pezzuti & Leite, 2013, S. skaios Pombal‐Jr., Carvalho‐Jr., Canelas & Bastos, 2010, and Scinax sp. (Nogueira et al, 2016)
Summary
Scinax Wagler, 1830 is one of the most speciose genus of treefrogs of the Neotropics and it encompasses more than 120 species (Frost, 2021; Segalla et al, 2021). The S. catharinae clade harbors species which are distributed along the east, central, and central-west regions of Brazil, northeastern Argentina and southern Paraguay and Uruguay (Duellman et al, 2016; Frost, 2021). Most species of the S. catharinae clade occur in coastal forest environments, while a few occur in phytophysiognomies (e.g., gallery forests) of the Brazilian Cerrado biome, such as S. canastrensis (Cardoso & Haddad, 1982), S. centralis Pombal & Bastos, 1996, S. goya (Andrade et al, 2018), S. machadoi (Bokermann & Sazima, 1973), S. pombali Lourenço, Carvalho, Baêta, Pezzuti & Leite, 2013, S. skaios Pombal‐Jr., Carvalho‐Jr., Canelas & Bastos, 2010, and Scinax sp.
