A new species of Scinax Wagler (Anura: Hylidae) from Cerrado of Brazil

Abstract

A new species of Scinax of central Brazil, closer to the Scinax maracaya (Cardoso & Sazima), from the Cerrado biome (open formations) is described. This new species is characterized by the following combination of traits: moderate size (males 28.4–30.8 mm snout vent length); presence of several flash orange-yellowish transversal stripes on thigh; vocal sac well developed; snout acuminate in profile; advertisement call with one note, 4–15 pulses, and dominant frequency 2.93–3.27 kHz. Description of the advertisement call and comments on natural history and habitat are provided.

Taxonomic review ofScinax fuscomarginatus(Lutz, 1925) and related species (Anura; Hylidae)

“…Scinax is currently the largest genus in the family Hylidae with 112 recognized species (Frost, ; Lourenço et al ., ), and more new species are being described frequently (e.g. 14 new species described in the last three years: Cardoso & Pombal, ; Lourenço, Nascimento & Pires, ; Faivovich, Gasparini & Haddad, ; Nunes, Carvalho & Pereira, ; Nunes & Pombal, , ; Pombal et al ., , ; Cruz, Nunes & De Lima, ; De Lima, Cruz & de Azevedo, ; Silva & Alves‐Silva, ; Lacerda, Peixoto & Feio, ; Nunes, Kwet & Pombal, ). The last phylogenetic assessment of this genus revealed two main clades, the Scinax catharinae clade, including the S. catharinae and Scinax perpusillus groups, and the Scinax ruber clade, including the Scinax rostratus and Scinax uruguayus groups, and 43 species not being assigned to any of the previous groups (Faivovich et al ., ).…”

First records of Scinax ruberoculatus Ferrão, Fraga, Moravec, Kaefer & Lima, 2018 (Anura, Hylidae) in the state of Amapá, eastern Amazon, Brazil, with comments on its vocalization and distribution

“…Although Camera et al depicted this note in their advertisement call figures, they did not mention it in the text, which indicates that they probably misinterpreted it as being part of the advertisement call. Some studies have also reported other species of Scinax which may emit aggressive calls shortly after the advertisement call (e.g., Drummond et al 2007;Bang et al 2017;Lopes et al 2020).…”
