FIGURE 12 in <p class="HeadingRunIn" align="left"><strong>A revision of the <em>Pauropsalta annulata </em>Goding & Froggatt species group (Hemiptera: Cicadidae) based on morphology, calling songs and ecology, with investigations into calling song structure, molecular phylogenetic relationships and a case of hybridisation between two subspecies</strong></p>
FIGURE 12. Male calling song structure of Pauropsalta notialis notialis subsp. nov. illustrated in expanded waveform plots (explained in Fig. 8), showing both buzzing and lilting components. The spectrogram at the bottom of the figure displays song frequency, which exhibits no modulation between the song components in this species. This specimen was recorded in the field at Concord (33°51'S 151°06'E).
