FIGURE 15 in Two new genera and five new species of Mugadina - like small grass cicadas (Hemiptera: Cicadidae: Cicadettini) from Central and Eastern Australia: comparative morphology, songs, behaviour and distributions

FIGURE 15. Comparison of Heremusina udeoecetes n. sp. song in terms of, (A), waveform plot (temporal structures of song), (B), spectrogram showing timbal emission frequencies, these concentrated in range ~11–17 kHz, but exhibiting no indication of systematic changes of frequencies during song emission, although minor frequency disturbances may occur at the start of each echeme; and (C), amplitude spectrum showing the dominant frequency envelope between 11.5–16.8 kHz, with the estimated dominant frequency at 13.9 kHz. Filtered to 3.5 kHz (A), and 7.5 kHz (C).
