Hyperophora brasiliensis Brunner von Wattenwyl, 1878

Fig. 10C, D ; 15A

Distribution: Argentina: Buenos Aires; Brazil: Mato Grosso do Sul, Paraná; Paraguay: Paraguari.

New record for the Paraná State.

Comments: The species presents a broad geographic distribution, restricted to the southern cone of South America. The species seems also to be abundant where it occurs, as several individuals were heard and seen when stridulating at night on bushes and other plants, up to two meters, both in the borders and in the interior of the forest. The females respond to the stridulation of males, in a duet behaviour.

Bioacoustics ( Fig. 11C–E ): Males stridulate continually at night, and the females respond to the male stridulation in a duet behaviour. Males produce short echemes, composed by three hemisyllables, in a crescendo of intensity. The response of females is emitted just after the male stridulation, and consists of a single syllable, similar to a “tic”, with smaller frequency than male stridulation, but not analyzed herein.

Dominant frequency: 15.8 ± 1 kHz.

Bandwidth: 6 ± 0.4 kHz.

Duration: Syllable: 0.08 ± 0.03 s.

Mute interval: Syllable: 2.8 ± 1 s.
