FIGURE 17. Audiospectrogram and oscillogram of two advertisement calls (part of a longer call series) of Cophyla puellarum sp. nov. recorded from paratype specimen UADBA-A 60237, at Point de Vue du Grand Moulin in Montagne d'Ambre National Park, on 10 December 2012, air temperature of ca 17˚C. The sounds above 2500 Hz represent other frogs or insects, and the initial intensity peaks at each call probably represent an artefact of the recording device or an abnormal sound emission of the recorded specimens.
