Quantitative analysis of the acoustic communication system in anurans is a relevant step toward understanding how acoustic traits variation is related to conspecific recognition and discrimination. Here, we report on the advertisement call variation of male Scinax fuscomarginatus at three levels: within-individual, between-individual, among-populations. We examined 635 advertisement calls of 127 individuals from 10 populations in Central Brazil. Fieldworks were carried out during eight breeding seasons, from 2008 to 2016. We used the coefficient of variation (CV), Analysis of Variance (ANOVA), Principal Component Analysis (PCA) and Multivariate Analysis of Variance (MANOVA) to evaluate whether the call features differed statistically. The advertisement call structure consisted of a single multipulsed note with stereotyped acoustic features. These features were statistically different at between-individual level and the relative variability (CV) was higher between-individual than within-individual of the same population. MANOVA performed with PCA scores indicates that call traits are different among populations. Hence, we suggest the advertisement call features of male S. fuscomarginatus show sufficient statistical differences for interindividual and interpopulation distinction. We also discuss the role of the stereotyped acoustic features on mate choice and intraspecific distinction.

Scinax x-signatus was originally described by Spix (1824) from \“ProvinciaBahiae\”. The holotype was lost during World War II and a neotype was not designated, thus leading to the synonymy of S. x-signatus to Hyla affinis and Hyla coerulea, both from Amazonas. Herein we present the phenotypic variation of morphological and morphometric characters of populations from states of Bahia and Amazonas. Additionally we provide the bioacoustic variation from state of Bahia. Bioacoustic results show an acoustically cohesive population in Bahia, however morphometric and morphological results show that these populations may not represent the same species. Our combined results show that Bahia populations of S. x-signatus are significantly different from population of Amazonas and a more comprehensive study with molecular data should corroborate that.

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 Paran\á, 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.
