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 whichremain 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 currentlyincluded in the S. uruguayus group, discussing some putative phenotypic synapomorphiesof 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 thatboth are valid and diagnosable species based on phenotypic evidence. Furthermore, ourresults show that S. pinima previously known only from its type locality, has a much widespreaddistribution than previously thought (including the Brazilian states of Parana´ , SantaCatarina, and Rio Grande do Sul), which, added to the biological information presented hereallows to suggest the removal of this species from the ?Data Deficient? IUCN Red List categoryto ?Least Concern?. Also, we describe a new species formerly reported as S. aff. pinimaand S. uruguayus from NE Argentina and some localities from the Brazilian State of RioGrande do Sul. All species are diagnosed and characterized using adult and larval morphology,osteology, vocalizations, cytogenetics, and natural history.
