New record for the Paraná State . Comments: The position of the genus within the Phaneropterinae is still unclear ( Cigliano et al. 2022 ). The species appears not to be broadly distributed within South American forests, considering its northernmost record ( Minas Gerais State , Brazil ). Bioacoustics ( Fig. 27 ): Males produce sequences of echemes, each one composed by four to seven echemes. Each echeme is composed by 25 to 35 syllables that are produced with increasing intensity. Dominant frequency : 16 ± 2 kHz. Bandwidth : 7 ± 1.7 kHz. Duration : Syllable: 4 ± 0.8 ms; Echeme: 40 ± 6 ms. Mute interval : Syllable: 12 ± 1 ms; Echeme: 1.9 ± 0.14 s .
