A revision of the Ewartia oldfieldi (Distant) species complex (Hemiptera: Cicadidae: Cicadettinae) with five new species from eastern and northern Australia
FIGURE 2. Digital illustrations comparing head and thorax morphology between different species in the Ewartia oldfieldi (Distant) species complex, including A: E. oldfieldi, B: E. roberti n. sp., C: E. lapidosa n. sp., D: E etesia n. sp., E: E. thamna n. sp., and F: E. carina n. sp.
FIGURE 9. Digital illustrations of male pygofer and genitalia morphology, viewed laterally from left (left) and ventrally (right). A: Ewartia roberti n. sp., Carina Heights (27 ° 30 ' S 153 ° 06 ' E); B: E. lapidosa n. sp., Bringalily State Forest (28 ° 11 ’ S 151 ° 07 ’ E); C: E. lapidosa n. sp., Miles (26 ° 37 ' S 150 ° 10 ' E). Scale bar represents 1 mm.
FIGURE 10. Map of central eastern Australia showing the known geographical distribution of Ewartia roberti n. sp. Larger symbols represent specimen records and smaller symbols are song recording or aural records.
FIGURE 14. Wave plots illustrating the structure of the simple mode of the male calling song of Ewartia roberti n. sp. from six different localities, including A: Binjour (25 ° 32 ' S 151 ° 30 ' E), B: Carina Heights (27 ° 30 ' S 153 ° 06 ' E), C: Linthorpe (27 ° 38 ' S 151 ° 39 ' E), D: Peak Crossing (27 ° 46 ' S 152 ° 46 ' E), E: Glenlyon Dam (28 ° 58 ' S 151 ° 28 ' E), and F: Wee Waa (30 ° 12 ’ S 149 ° 36 ’ E). Each plot includes three phrases (each a single echeme followed by a gap). The recording from Linthorpe (C) was made at dusk, whereas all other recordings were captured during the day. All recordings were obtained using RS 1 (see Methods).
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 90 th percentile of each amplitude spectrum). Recordings were obtained using RS 3 (A, C, D) and RS 1 (B) (see Methods).
