FIGURE 7. Male calling song structure of Myopsalta bassiana n. sp. from a recording obtained at Acton (35 ° 16 ' S 149 ° 07 ' E) by the author using RS 5 (see Methods). (A) Wave plot of two complete phrases, each containing a sequence of discrete syllables that condenses into a long echeme, which builds in amplitude before ending abruptly and being followed by a short echeme or macrosyllable. (B) Expanded wave plot showing the structure of the latter half of a phrase, including the conspicuous amplitude modulation of the long echeme and the short echeme that follows. (C) Spectrogram showing the highest amplitude frequency plateau and dominant frequency.

(A) Wave plot illustrating three phrases, each commencing with two single syllables and one or two macrosyllables, followed by a series of five echemes and concluding with a final macrosyllable. (B) Expanded wave plot showing the detailed structure of one phrase. (C) Spectrogram showing the highest amplitude frequency plateau and dominant frequency.
