FIGURE 7 in A revision of the Ewartia oldfieldi (Distant) species complex (Hemiptera: Cicadidae: Cicadettinae) with five new species from eastern and northern Australia

FIGURE 7. Frequency spectra comparisons between taxa in the Ewartia oldfieldi (Distant) species complex, including A: E. oldfieldi (from Woodgate: 25°08'S 152°29'E), B: E. roberti n. sp. (from Glenlyon Dam: 28°58'S 151°28'E), C: E. lapidosa n. sp. (long subphrase, from Bringalily State Forest: 28°11'S 151°07'E), and D: E. lapidosa n. sp. (short subphrase, from Miles: 27°37'S 150°10'E). The horizontal bars show the ranges of each highest amplitude frequency plateau (bounded by the 90th percentile of each amplitude spectrum). Recordings were obtained using RS3 (A, C, D) and RS1 (B) (see Methods).
