[email protected] The release call in anurans is an acoustic-mechanical response to a male-male mating attempt. Some studies show that the temporal structure of these vocalizations could be phylogenetically informative. In this study, we analyzeda total of 110 release calls fromseven individuals (Hypsibo aspulchellus: n=2; H. cordobae: n=5). Release calls were induced in the laboratory by a slight pressure in the axillary region, simulating an amplexus. The acoustic signals were digitalized and analyzed by means of oscillograms, sonograms and power spectra using the software Adobe® AuditionTM 1.0. Each call series was characterized by three parameters: (1) call duration [ms]; (2) intercall duration [ms]; and (3) dominant frequency [Hz]. We calculated means, standard deviations, maximum and minimum for each individual variable. Species comparisons were performed using ANOVA. The release call in both species consists of a single note. H. pulchellus call has an average duration of 11.6 ms, being higher than that of H. cordobae. The mean intercall duration (274.05 ms) and the mean dominant frequency were higher in H. cordobae (2388.95 Hz) than in H. pulchellus (1604.82 Hz). Call duration and dominant frequency showed significant differences between species (p
