The presence of Scinax altae (Dunn, 1933) in Costa Rica, with redescription of its advertisement call

摘要: Scinax altae is a treefrog hitherto known to occur only in Panama. Herein, we report two populations referred as S. altae by morphology, bioacoustics and genetics in the Southeastern Pacific region of Costa Rica. We present new maps showing the geographic distribution and hiatus between S. staufferi and S. altae. In addition, we aimed to redescribe the advertisement calls of Scinax altae and Scinax staufferi, based on new bioacoustic analysis and interpretation techniques, in order to evaluate their differential diagnosis.
