Figure 9 in Arenopsaltria nubivena (Cicadidae: Cicadinae: Cryptotympanini) from the Arid Regions of Central Australia and Southwest Western Australia

Figure 9. Comparative plots of amplitude spectra of: (A) Arenopsaltria pygmaea from 14 km northeast of Jurien Bay, Western Australia; (B) Arenopsaltria fullo, from Mullaloo Beach, north of Perth, Western Australia; (C–F) Arenopsaltria nubivena, from, respectively; 5.6 km west of Windorah, southwest Queensland; 72 km south of Cooper Creek crossing, Birdsville Track, Strzelecki Desert, South Australia; 105 km east southeast of Yulara, southern Northern Territory; and 18 km east of Eneabba, Western Australia, respectively. Note the weak extensions in all the plots to frequencies higher than the defined dominant frequency. The horizontal bars define the high amplitude frequency envelope of each spectrum, used to estimate the dominant frequency and the nominal bandwidth of each song. Each spectrum shown only between 3 to 16 kHz.
