Figure 6. Advertisement call of Phyllodytes magnus sp. nov.

Figure 6

Graphic representations of the advertisement call of the paratype MZUESC 18265 (A–D) and of the holotype MZUESC 18264 (E–H) of Phyllodytes magnus sp. nov. A and E: waveform of an entire call. B and F: waveform and spectrogram of one note; vertical arrow in waveform in B indicates the constriction of the waveform (see text for explanation); horizontal arrows in the spectrogram indicate the harmonics; vertical dashed lines in the spectrograms indicate the position of the spectrogram slices. C and G: spectrogram slice of the first part of the note (indicated by the left vertical line) in B and F, respectively; arrows in C indicate the sidebands, multiples of ∼0.4 kHz (see text for explanation). D and H: spectrogram slice of the second part of the note (indicated by the right vertical line) in B and F, respectively; arrows indicate the harmonics, multiples of ∼1.07 kHz (see text for explanation). Spectrographic views settings: window type: Hann, window size: 512 samples, 3 dB filter bandwidth: 124 Hz, time grid overlap: 90%, time grid size: 51 samples, frequency grid DFT size: 512 samples, frequency grid spacing: 86.1 Hz. Call voucher –FNJV 40997 (holotype) and FNJV 41382-41384 (MZUESC 18265).
