Conocephalus longipes (Redtenbacher, 1891)

Calling song

Comprised of a trill. Phrases with two types of syllables. The first type of syllable exhibits greater amplitude, lasting 0.005 ± 0.0007 (0.004 –0.006) seconds. The second, longerlasting syllable lasts about 0.017 ± 0.0006 (0.0166 –0.0184) seconds. There is an interval between syllables of 0.004 ± 0.0004 (0.004 –0.0054) seconds, with 75.8 ± 2.16 (73–78) notes emitted per second. The signal displays a peak frequency of 11.03 ± 1.39 (10.1–13.8) kHz, with a bandwidth of 12.34 ± 0.07 (12.18–12.37) kHz ( Figure 8A ).

Collection site

Parque Natural Municipal Saint–Hilaire. Males were collected and recorded on 25 November 2019, at 11 am, positioned 0.2 metres above the ground, with a temperature of 18°C. The males produce signals in areas close to the ground, within typical open-field vegetation ( Figures 8A and 10A ).
