FIGURE 4 A–C in Similar look but different song: a new Cicadetta species in the montana complex (Insecta, Hemiptera, Cicadidae)

FIGURE 4 A–C. Frequency pattern of a typical long echeme produced by C. cantilatrix sp. nov. A, Oscillogram; B, Spectrogram (time vs frequency vs amplitude, colour amplitude scale given on the right) and mean spectrum (frequency vs amplitude) of the first and second parts of the echeme; C, Dominant frequency variation along the echeme. Frequency analysis parameters: Hamming window, overlap = 87.5%, frequency resolution = 43 Hz. Short echeme showed similar frequency parameters.
