Scaphura elegans (Serville, 1838)

Calling song

Comprising two types of interspersed echemmes, with the second part exhibiting shorter duration, lower amplitude, and a smaller number of syllables. The echemmes last 0.663 ± 0.05 (0.585 –0.706) seconds with intervals between them lasting 3.64 ± 0.86 (2.97–4.78) seconds. Within each echemme, there are two types of syllables. The first type of echemme lasts 0.194 ± 0.02 (0.156 –0.226) seconds, containing 18.66 ± 3.44 (15– 24) syllables, with an interval of 3.64 ± 0.86 (2.97–4.78) seconds. The second type of echemme lasts 0.135 ± 0.03 (0.76–0.165) seconds, with 5.66 ± 2.42 (2–8) syllables, and an interval of 0.34 ± 0.04 (0.29–0.404) seconds. The peak frequency is 12.42 ± 0.09 (12.30– 12.55) kHz, with a bandwidth of 5.13 ± 0.43 (4.68–5.81) kHz.

Collection site: Porto Alegre, near the Parque Natural Municipal Saint-Hilaire. The male was recorded and collected on February 1, 2022, at 4 pm, with a temperature of 25°C. The organism was observed producing signals in canopy locations, approximately 3 metres above ground level ( Figures 11C and 12C ).

Remarks

Calling song previously described by Fianco et al. (2022).

Anaulacomera sp. 1

Calling song: composed of two types of echemmes. The signal has a duration of 2.76 ± 0.21 (2.61–2.92) seconds. The first type of echemme lasts 0.64 ± 0.03 (0.624 – 0.667) seconds, with 29.5 ± 2.12 (28–31) syllables. The second type of echemme lasts 2.05 ± 0.22 (1.891–2.21) seconds, with 81.5 ± 6.36 (77–86) notes. The peak frequency is 15.04 ± 0.18 (14.91–15.17) kHz, with a bandwidth of 7.91 ± 0.55 (7.31–8.43) kHz.

Collection site

EstaÇão Ecológica do Taim. The males were recorded and collected on February 9, 2021, at 5 pm, with a temperature of 24°C. The males were observed producing signals in shrubs close to flooded regions, up to 2 metres high. The signal is produced for most of the day, starting at 10 am and ending at 6 pm ( Figures 11D and 12D ).

Remarks

We are waiting for future studies to confirm the identification at the species level.
