Calling song (Fig. 26). Examination of the calling song of M. parvula n. sp. reveals the phrase durations to be quite variable, often prolonged. From a small sample of available recordings ( n =2), phrase durations ranged from 3.7 s to >47 s and this variation was a consequence of the number of smaller subphrases incorporated into each phrase. Each subphrase comprises a long macrosyllable (0.05–0.08 s duration; sometimes preceded by a syllable and gap of 0.007–0.008 s and 0.008–0.017 s duration, respectively), a gap of 0.020–0.025 s duration and a syllable sequence (0.12–0.19 s duration, containing 5–7 syllables separated by gaps of 0.020–0.025 s duration). Each phrase concludes with a drawn out syllable sequence (0.5–1.0 s duration, containing 18–35 syllables), followed by a gap (0.039–0.042 s duration), a short macrosyllable (0.017–0.022 s duration) and a longer gap (0.10–0.12 s duration). Based upon the observations of the calling behaviour in other Myopsalta species, it is considered likely that the female would respond with a wing-flick signal during the long gap at the end of each phrase. The calling song maintains an even frequency distribution throughout, with a high amplitude plateau of 12.9– 19.3 kHz and a dominant frequency between 13.1 and 17.7 kHz.
