FIGURE 16. A, Drymopsalta hobsoni sp. nov. and B, Drymopsalta wallumi sp. nov. Time expanded envelope curves of the ticks within the chirps of the normal calling songs showing the similarities of the temporal structures of the ticks. These similarities extend to the other Drymopsalta species. Within these plots, the tick repetition rates and the inter-pulse durations (between primary and secondary pulses) are, respectively, for A, 5.73±0.05 and 2.12±0.15 ms; for B, 4.44±0.18 and 2.07±0.19 ms. Field recordings filtered to 10 kHz (A) and 15 kHz (B).
