“…For example, the characters used to define Julianus are identical to those of Scinax [9]. Although ignored by Duellman et al [9] and by Ferrão et al [69], there are adult and larval morphological putative synapomorphies that diagnose the Scinax uruguayus group [2,3,6] as commented earlier in this study, and further discussed below.…”

The genus Scinax currently includes more than 120 species, recovered in two major clades, the S. catharinae and the S. ruber clades. The latter comprises 75 species, most of which remain unassigned to any species groups, while 12 are included in the S. rostratus and S. uruguayus groups. In this paper we present a taxonomic review of the two species currently included in the S. uruguayus group, discussing some putative phenotypic synapomorphies of this group. Although S. pinima and S. uruguayus have been considered as distinct species, this has been based on scant evidence, and several authors doubted of their distinctiveness. Our study of available specimens of S. pinima and S. uruguayus corroborates that both are valid and diagnosable species based on phenotypic evidence. Furthermore, our results show that S. pinima previously known only from its type locality, has a much widespread distribution than previously thought (including the Brazilian states of Paraná, Santa Catarina, and Rio Grande do Sul), which, added to the biological information presented here allows to suggest the removal of this species from the “Data Deficient” IUCN Red List category to “Least Concern”. Also, we describe a new species formerly reported as S. aff. pinima and S. uruguayus from NE Argentina and some localities from the Brazilian State of Rio Grande do Sul. All species are diagnosed and characterized using adult and larval morphology, osteology, vocalizations, cytogenetics, and natural history.

“…The dorsal pattern with large irregular dark blotches, commonly with dark X-shaped marks composed of one or two pairs of inverted parenthesis-like blotches, distinguishes Scinax x-signatus from S. altae, S. alter, S. auratus, S. boesemani, S. caldarum, S. cretatus, S. crospedospilus, S. curicica, S. cuspidatus, S. duartei, S. exiguus, S. fuscomarginatus, S. imbegue, S. juncae, S. madeirae, S. oreites, S. pachycrus, S. quinquefasciatus, S. ruber, S. squalirostris, S. staufferi, S. tsachila, S. tymbamirim, and S. villasboasi (variable number of dorsal and/or lateral stripes; e.g., Duellman, 1970;Lutz, 1973;Duellman & Wiens, 1993;Pugliese et al, 2004;Nunes et al, 2012;Brusquetti et al, 2014;Ron et al, 2018;this study), and S. blairi, S. cabralensis, S. chiquitanus, S. danae, S. iquitorum, S. lindsayi, S. maracaya, and S. strussmannae (scattered or homogeneously distributed spots and/or irregular blotches; e.g., Fouquette & Pyburn, 1972;Cardoso & Sazima, 1980;De la Riva, 1990;Drummond et al, 2007;Ferrão et al, 2018b; this study).…”

A neotype for Hyla x-signata Spix, 1824 (Amphibia, Anura, Hylidae)

The uncertain identity of Hyla x-signata Spix, 1824 has been a pervasive problem in the taxonomy of the genus Scinax. A species supposedly distributed from northeastern Brazil northwards to Colombia and Venezuela, described in a few lines without much information and with an accompanying figure, and its type specimen lost during World War II, combined to produce a curious situation. Twenty-one of the 39 species of the S. ruber Clade described in the last 50 years were considered to require a diagnosis from S. x-signatus by their authors. In most cases these had no other alternative than to gather information about this species from indirect sources, frequently pointing out the problems associated with its uncertain identity. In this paper, we review the taxonomic history of Hyla x-signata, designate a neotype, provide a redescription including advertisement call and sequence data, and diagnose it from all other species of the S. ruber Clade.

“…The upper Madeira River is characterized by high biodiversity; several priority areas for conservation are identified in this region (Capobianco 2001). Yet, recent studies have revealed that knowledge of the species diversity of amphibians inhabiting forests in the upper Madeira River is still incomplete, and description of new species is ongoing (e.g., Simões et al 2010;Brcko et al 2013;Ferrão et al 2016;Ferrão et al 2018). The new taxon described herein is the first species of Dendropsophus described from the Brazilian portion of the upper Madeira River, and at least one other new Dendropsophus species is awaiting formal description (work in preparation).…”

Recent studies have shown that species diversity of the South American frog genus Dendropsophus is significantly underestimated, especially in Amazonia. Herein, through integrative taxonomy a new species of Dendropsophus from the east bank of the upper Madeira River, Brazil is described. Based on molecular phylogenetic and morphological analyses, the new species is referred to the D. microcephalus species group, where it is differentiated from its congeners mainly by having a green bilobate vocal sac and an advertisement call comprising 1–4 monophasic notes emitted with a dominant frequency of 8,979–9,606 Hz. Based on intensive sampling conducted in the study area over the last ten years, the new species is restricted to the east bank of the upper Madeira River, although its geographic range is expected to include Bolivian forests close to the type locality.
