FIGURE 3 in Mikrischyrum musicum, a new katydid species from montane rainforest in southern Ecuador with complex pure-tone calling song (Orthoptera: Tettigoniidae: Pseudophyllinae: Platyphyllini)

FIGURE 3. Calling song of Mikrischyrum musicum: A. oscillogram of complete pulse train (20°C, holotype, recording cbt-019s04r03), B. first group of four pulses of A in higher resolution (and photo of holotype staged at day), C. linear spectrogram, D. zero-crossing analysis of one pulse, E. field recording together with two other katydid species, the arrow points at first pulse of the M. musicum sequence (13°C, cbt019x01r01, 14 August 1998), F. spectrogram taken from this recording with the distinctive peak of the new species, G. spectrogram of an unknown katydid species, showing the M. musicum peak too, H. spectrogram of an undescribed species of Aemasia (also Platyphyllini, song known from collected males, Braun 2002: Figs. 6.2.4, 6.3.3), based on the second call right after the end of the M. musicum sequence.
