FIGURE 29. Frequency spectra comparisons between taxa in the Ewartia oldfieldi (Distant) species complex, including A: Ewartia etesia n. sp. (from Wangi Tourist Park: 13°08'S 130°39'E), B: E. etesia n. sp. (from 76 km E. of Mataranka: 14°55'S 133°43'E), C: E. thamna n. sp. (from 76 km E. of Mataranka: 14°55'S 133°43'E) and D: E. carina n. sp. (from McIlwraith Range: 13°43'S, 143°19'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) and RS5 (B–D) (see Methods).
