calls (Gerhardt, 1988 ) and tadpoles are morphologically very different from adults, anuran species descriptions and taxonomic appraisals can benefit from the systematic use of such characters. In fact, larval and bioacoustical characters have been extremely valuable in anuran systematics (Blair

sounds were filtered (High Pass 250 Hz) and subsequently peak normalized with Audacity 2.0.2 software. Recorded sounds were analyzed with Raven 1.4 software (Bioacoustics Research Program, 2011). From each individual recorded, 6 calls were selected for analysis based on recording quality. The following

To quantify the variability in the calls, the coefficient of variation (CV) of acoustic parameters was calculated as the ratio of the

We provide a partial revision of the microhylid frogs of the genus Anodonthyla, endemic to Madagascar, based on comprehensive molecular, bioacoustic and morphological data sets that include newly collected specimens from multiple localities. The molecular trees provide strong evidence for the polyphyly of several nominal species as they were previously defined, especially of Anodonthyla boulengeri and A. nigrigularis. As a consequence, we here resurrect the nomen Mantella pollicaris Boettger as Anodonthyla pollicaris from the synonymy of A. boulengeri, and we describe four new species, all with strong genetic divergences to other nominal species: Anodonthyla emilei from Ranomafana National Park, a comparatively medium- sized species characterized by a multi-note advertisement call with high note repetition rate; A. theoi from Manombo Special Reserve, a small species characterized by low note repetition rate, long note duration and high spectral call frequency; A. vallani, a medium-sized species from Ambohitantely Special Reserve, characterized by low note repetition rate, long note duration and low spectral call frequency; and A. jeanbai, a small species from Andohahela National Park, characterized by a long and narrow head, presence of short dorsolateral folds, a very short first finger, and a yellowish ventral colour. A further candidate species comprises populations previously assigned to A. boulengeri from the Ranomafana region, which we do not describe because the corresponding data set is too fragmentary, and we refer to it as A. sp. aff. boulengeri ‘Ranomafana’. The molecular phylogeny indicates recurrent shifts between high and low note repetition rates in calls, based mainly on three strongly supported sister groups: A. moramora with low repetition rate and A. nigrigularis with moderately low repetition rate; A. theoi with low repetition rate and A. pollicaris with high repetition rate; and A. vallani with low repetition rate and A. sp. aff. boulengeri ‘Ranomafana’ with high repetition rate. The two species with the northernmost ranges, A. hutchisoni and A. boulengeri, are phylogenetically nested within clades of species occurring further south, confirming that the center of origin of the genus Anodonthyla was most likely in the South East of Madagascar.

Advertisement call is a complex signal that can vary at different scales and the characterization of this variation is crucial to understand its adaptive function. In our study, we examined different factors that could influence intra and inter-population call variation in Odontophrynus cordobae. We analyzed calls of individuals from different breeding sites across the species distribution, including a syntopic site with their related species O. americanus. Dominant frequency, pulse rate, call duration and pulses/call were the acoustic parameters that showed the lowest intra-individual variation (CV ≤ 3%). The discriminant function analysis (DFA) assigned 92% of calls to the correct individual, indicating that the advertisement calls of O. cordobae are individually distinctive. Univariate and multivariate statistical analysis showed a significant contribution of pulse rate in differentiation of populations. Interpulse interval and pulse rate showed a moderate clinal variation, even when syntopic populations were excluded from the analysis. We found no association between acoustic and linear geographical or altitudinal distances and observed an evident divergence between the syntopic population and the other populations analyzed. This result is reinforced by DFA, which showed a differentiation among syntopic and allopatric populations of O. cordobae. We discuss our results from the hypothesis of a possible character displacement influencing call properties in this species in syntopy with their related species O. americanus. However, new syntopic areas and tests of female preferences would be needed to strengthen our results.
