The Atelopus (or harlequin frogs) have become a symbol of the ongoing efforts to conserve biodiversity in Ecuador over past few decades. ignescens , also known as jambato, was previously considered be an extinct species until it rediscovered Andean locality Angamarca, Ecuador. This study presents and describes calls for first time. These are low intensity sounds that comprise repertoire three distinct call types: tonal, short pulsed call. They different spectral temporal characteristics. most notable difference their structure is presence or absence pulses frequency modulation observed tonal calls. In terms characteristics, mean dominant 1.7 kHz, with up 11 harmonics visible. A peculiar feature Jambato tympanic middle ear, characteristic majority species. these structures, however, does not toads deaf since they seem extratympanic mechanisms audition. It our hope contribution will stimulate further research into bioacoustics behavior this endangered relatively unknown group anurans.
