There are many species of Orthoptera that remain undescribed and their acoustic signals are unknown. This study aims to measure and quantify the mechanics of wing vibration, sound production and acoustic properties of the hearing system in a new genus of Pseudophyllinae with taxonomic descriptions of two new species. The calling behaviour and wing mechanics of males were measured using micro-scanning laser Doppler vibrometry, microscopy, and ultrasound sensitive equipment. The resonant properties of the acoustic pinnae of the ears were obtained <i>via</i> μ-CT scanning and PeerJWing mechanics and acoustic communication of a new genus of sylvan katydid (Orthoptera: Tettigoniidae: Pseudophyllinae) from the Central Cordillera cloud forest of Colombia.PMC11216201NE/T014806/1Sarria-S FAHolmes LBWoodrow CMontealegre-Z FCeliker EfalseWing mechanics and acoustic communication of a new genus of sylvan katydid (Orthoptera: Tettigoniidae: Pseudophyllinae) from the Central Cordillera cloud forest of Colombia.Stridulation is used by male katydids to produce sound <i>via</i> the rubbing together of their specialised forewings, either by sustained or interrupted sweeps of the file producing different tones and call structures.
