Bioacoustics of Meroncidius flavolimbatus

Comments: It is outstanding that a species that were recorded for the first time for the Paraná State is very common in the studied sites in the ParNa Iguaçu. The individuals are easily found at night, always around tree barks or associated with bromeliad leaves. Bioacoustics ( Fig. 30A–C ): Males produce very peculiar sequences of sounds only at night. Initially, before the stridulation itself, males produce a series of sounds with their bodies, when they beat the substrate with the abdomen, producing ca. 10–15 sequences of beats, each one composed by three to five beats on the substrate. The stridulation is formed by one echeme where nine to twelve syllables appear in a crescendo of intensity. Dominant frequency : Stridulation: 14 ± 1.4 kHz; Beats:187.5 ± 54 Hz. Bandwidth : 6.4 ± 0.9 kHz (stridulation). Duration : Syllable: 0.43 ± 0.07 s ; Beat: 0.13 ± 0.04 s ; one beat sequence: 0.95 ± 0.02 s ; sum of beat sequences: 12 ± 2 s. Mute interval : Syllable: 0.5 ± 0.08 s ; Echeme: 89 ± 47 s; Beat: 0.1 ± 0.04 s ; beat sequence: 0.2 ± 0.003 s .
