Fig. 16A, B View FIGURE 16

Distribution: Argentina: Misiones; Brazil: Paraná.

New record for Brazil and for the Paraná State.

Comments: This is the first record of the species after its original description, although individuals seem to be quite common in the ParNa Iguaçu. They were massively attracted to light traps, where they could be easily collected (we even decided not to collect all of them). Individuals did not feed when reared in the laboratory, rejecting any food we offer to them (fruits, vegetables, grass, fish food flakes).

Bioacoustics ( Fig. 18A–C View FIGURE 18 ): Males continually stridulate through the night and the day, when they produce short echemes of two types. The first with high and constant amplitude, composed by four to six syllables that are regularly spaced. The second, otherwise, present moderate amplitude, but beginning and ending with syllables that reach slower amplitudes than the middle syllables. Syllables of this second type of echeme are very grouped, i.e., the mute interval is very short, and the interval between syllables only increases after ca. half of the echeme.

Dominant frequency: 62.3 ± 21.6 kHz.

Bandwidth: 19.7 ± 3.8 kHz.

Duration: Syllable: 8 ± 1 ms; Echeme: 248 ± 42 ms.

Mute interval: Pulse: 0.1 ± 0.03 s; Syllable: 9.6 ± 4.7 s; Echeme: 500 ± 326 s.
