FIGURE 12 in The genus Tibicina Kolenati, 1857 in Morocco (Hemiptera: Cicadidae: Tibicininae): taxonomic assessment from integrative research

FIGURE 12. Calling song recording of T. maldesi with a digitization at 44.1 kHz sampling frequency. A, spectra (frequency vs. absolute amplitude). B, spectrogram and C, oscillogram (from top to bottom) of the end of one sequence followed by the start of a second sequence having an increasing progressive amplitude. D, oscillogram of a part of A showing groups of pulses (slow amplitude modulation). E, detailed spectrogram and F, oscillogram of a part of D showing a train of groups of pulses in detail. Number of males analyzed: N = 3; Number of measurements for sampling: n = 140. For abbreviations and spectrum abbreviations, see Fig. 9.
