FIGURE 4 in A new Neotibicen cicada subspecies (Hemiptera: Cicadidae) from the southeastern USA forms hybrid zones with a widespread relative despite a divergent male calling song

FIGURE 4. Neotibicen similaris similaris, field recording of male calling song from Wakulla Co., Florida (recording 08.US.FL.FOR.T01.WAV). Each panel shows a waveform above a spectrogram; A, complete song phrase, with annotation identifying two parts in the main phrase that differ in rate of alternation between high- and low-pitched echemes; B, zoom centered about 0.48 s into the clip in A, at the transition from part I to part II; C, further zoom of part I; D, further zoom of part II; E, segment of song that precedes and follows the main phrase. Sound energy below 1.8 kHz has been removed.Published as part of Marshall, David C. & Hill, Kathy B.
