FIGURE 11. Map of mainland eastern Australia showing the geographical distributions of Myopsalta gordoni n. sp. in Queensland, M. leona n. sp. in Queensland, New South Wales and the Northern Territory and M. longicauda n. sp. in Queensland and New South Wales. Large symbols represent specimen records and smaller symbols denote audio recordings or aural observations.
FIGURE 13. Male calling song structure of Myopsalta leona n. sp. from a recording obtained at Eidsvold (25 ° 22 ' S 151 ° 08 ' E) by the author using RS 1 (see Methods). (A) Wave plot of two complete phrases, each containing a long echeme with characteristic amplitude modulation followed by a macrosyllable and in the initial case an additional syllable. (B) Expanded wave plot showing the detailed structure of the maximum amplitude component of the long echeme. (C) Expanded wave plot showing the detailed structure of the end of the long echeme followed by a macrosyllable and additional syllable. (D) Spectrogram showing the highest amplitude frequency plateau and dominant frequency.
