  "abstract": "The Spix's snouted treefrog Scinax nebulosus is one of 13 recognised species in the Scinax rostratus group, distributed from the Guiana region through eastern and southwestern Amazonia to north-eastern Brazil. Previous molecular studies identified up to five evolutionary lineages, raising taxonomic uncertainties. Here, we integrate mitochondrial (16S rRNA, n = 121), morphological (n = 587), and bioacoustic (n = 335) data to test the existence of species boundaries within the S. nebulosus complex. DNA-based delimitation recovered seven operational taxonomic units (OTUs), six of which were supported by morphological and bioacoustic evidence and thus recognised as confirmed candidate species (CCS). Two OTUs correspond to the nominal species S. nebulosus and S. constrictus. The lineage from the Guiana region corresponds to Scinax cynocephalus (Hyla cynocephala), which we resurrect from synonymy with S. nebulosus. The remaining three CCS are described as new species from the northern portion of north-eastern Brazil, the Xingu-Tapajós interfluve and the region north of the lower River Amazon, and southwestern Brazilian and Bolivian Amazonia. Given acoustic divergence within one OUT, we suspect the existence of additional species boundaries or introgression, which deserve further investigation using genomic data and finer-scale phenotypic examination.",
