FIGURE 12. Heremusina udeoecetes n. sp. Waveform plots, based on field recordings at 11 km N.W. along Tanami Desert Road, 20 km north of Alice Springs, in low grassland. Figs. A, D show the characteristic repeated echemes, these having durations ranging between 272–332 ms, each commencing with 2–9 isolated pulses, followed by a sequence of closely spaced pulses; an isolated pulse is emitted at end of each echeme. Figs. B, D are time expanded waveform plots showing more detail of the pulses. The initial pulses (Fig. B) are isolated pulses, these changing to doublet pulses within the continuous echeme segment. Pulses (including doublet pulses) have repetition rates varying between 160–193 Hz. (C), shows the final segment of an echeme in which the pulses alternate between single and double pulses, followed by the single isolated final pulse. Filtered to 3.5 kHz.
