【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2014v27n4p93 Herein, we report the first record of the torrent frogHylodes heyeriin Santa Catarina State, South Brazil, previously known from localities along the Atlantic Rainforest in the states of São Paulo and Paraná. We also performed an acoustic comparison between the calls ofH. heyeriandH. perplicatusdue to their morphological similarity and because now they could be found in sympatry. There was a greater variation in advertisement call duration for both species, than previously stated in the literature, probably related to variation in air temperature. To distinguish the two species, besides the differences in dominant frequency, a temporal parameter that could be used was the interval between notes, but call duration should not be used due to the influence of air temperature. Our findings reinforce the urgency for more field activities to enhance our knowledge of the geographic distribution of anuran amphibians, to promote their conservation, and to call attention to the importance of detailed acoustic analysis to distinguish cryptic species.
