Abstract

The advertisement calls of the frog species Leptodactylus lithonaetes and Pristimantis vilarsi are described for the first time based on calls recorded in the Venezuelan State of Amazonas. The call of L. lithonaetes bears an overall resemblance to that of L. rugosus, suggesting a sister-group relationship between the two species. The call of Pristimantis vilarsi is similar to those of other species in the P. conspicillatus species group.
