Substrate-borne vibrations used during acoustic communication and the existence of courtship songs in some species of the genus Anaxipha (Saussure) (Orthoptera: Trigonidiidae: Trigonidiinae)

Oscillograms of the calling and courtship songs of the four species of Anaxipha. A1. A. exigua calling song; A2. A. exigua courtship song; B1. A. tinnulacita calling song; B2. A. tinnulacita courtship song; C1. A. tinnulenta calling song; C2. A. tinnulenta courtship song; D1. A. thomasi calling song; D2. A. thomasi courtship song. All audio files were normalized to -3 dBFS for comparison. Y-axis represents amplitude and is analogous to dBFS (full scale).
