Pseudophyllinae Burmeister 1838
4.4. Pinnae in the Pseudophyllinae and Meconematinae It would be sensible to predict, based on these findings, that pseudophyllines which communicate at frequencies beyond the function provided by the acoustic trachea (< 60 kHz; Celiker et al., 2020) may have lost function of the trachea, switching instead to utilising the high amplitude gains of the external auditory pinnae (Pulver et al., 2022) for conspecific sound reception (Mason et al., 1991). Morphological data we are collecting as a wider study of katydid auditory systems supports this hypothesis (Woodrow, unpublished). This is likely to also be the case in the extreme ultrasonic Meconematinae (Supersonus and Arachnoscelis spp.), where calling song frequencies range from ~70 kHz over 150 kHz. Wider comparative studies of auditory trachea and pinnae function, combined with numerical simulation and biophysical experimentation, are in process to develop this hypothesis.

This study was funded by a European Research Council Grant ERCCoG-2017-773067 (to FMZ for the project “The Insect Cochlea”) and an NSF - NERC grant NSF DEB-1937815 - NE/T014806/1 (to FMZ). Author contributions CW conducted micro-CT scans, 3D printing, data collection and analysis, and writing. FMZ conducted song recording, specimen collection, permits, supervised, and oversaw the study.Published as part of Woodrow, Charlie & Montealegre-Z, Fernando, 2023, Auditory system biophysics in a new species of false-leaf katydid (Tettigoniidae: Pseudophyllinae) supports a hypothesis of broadband ultrasound reception, pp. 94-104 in Zoologischer Anzeiger 304 on pages 101-102, DOI: 10.1016/j.jcz.2023.04.002, http://zenodo.org/record/816430

Eubliastes spp
4.2. Acoustics of Eubliastes spp. The song of E. viridicorpus is classic for members of the Cocconotini, showing discrete pure tone pulses with a similar envelope structure to other pseudophyllines (Baker et al., 2019; Stumpner et al., 2013) peaks at 23.4 kHz and is most similar to that of E. aethiops, which is also comprised of two syllables at a similar peak frequency (23.9 kHz, Fig. A1). However in E. aethiops the frequency spectrum has a wider bandwidth of 11.9 kHz (20 dB below the peak) compared to 2.2 kHz in E. viridicorpus, and does not show the additional frequency component towards 12 kHz as seen in E. viridicorpus. This song peak frequency range seems to be characteristic of the genus with E. chlorodictyon and E. pollonerae singing at and 25.4 and 25.5 kHz respectively (Figs. A2,A 3; Montealegre-Z and Morris, 1999; ter Hofstede et al., 2020).The same could be said of the two syllable temporal pattern of the song, but more recordings of other extant species (acoustic data is currently only available for four species) would be beneficial for future comparisons. The song of E. viridicorpus is also interesting in that the high amplitude component is at the start of each syllable rather than the end. This is similar to the song structure of E. chlorodictyon (Montealegre-Z and Morris, 1999), but differs from E. aethiops (Fig. A1) and E. pollonerae (ter Hofstede et al., 2020). This difference is not due to differences in stridulatory file anatomy, but instead indicates that the pattern of wing motion during stridulation differs, as the loudest component of the signal is produced during wing closure (Montealegre-Z., 2005; Montealegre-Z et al., 2006; Nielsen and Dreisig, 1970). Although tremulation was observed in the field, we were not able to record tremulatory signals in the laboratory. We hypothesise that E. viridicorpus utilises wing velocity to generate the lower peak of the song spectrum, but with a mirror tuned to the higher frequency peak of the spectrum (the first order harmonic) to optimise energy use.Published as part of Woodrow, Charlie & Montealegre-Z, Fernando, 2023, Auditory system biophysics in a new species of false-leaf katydid (Tettigoniidae: Pseudophyllinae) supports a hypothesis of broadband ultrasound reception, pp. 94-104 in Zoologischer Anzeiger 304 on page 101, DOI: 10.1016/j.jcz.2023.04.002, http://zenodo.org/record/816430
