The study of intraspecific variation of acoustic signals and its relationship with genetic divergence is important for understanding the origin of divergence in communication systems. We studied geographical variation in the acoustic structure of advertisement calls from five populations of the four‐eyed frog, P leurodema thaul , and its relationship with the genetic divergence among these populations. By analyzing temporal and spectral parameters of the advertisement calls, we report that the signals of northern, central, and southern populations have remarkable differences between them. A phylogeographical analysis from a mitochondrial DNA fragment demonstrated three phylogenetic groups coincident with those found with the bioacoustics analysis. Furthermore, bioacoustic and genetic distances show significant correlations after controlling for geographical distance. These results suggest that behavioural divergence among populations of P . thaul has a phylogenetic basis, supporting three evolutionary units within this species, as well as prompting the exploration of divergence processes in the sound communication system of this species. © 2013 The Linnean Society of London, Biological Journal of the Linnean Society , 2013, 110 , 142–155.
