Conocephalus (Anisoptera) goianus Piza

( Figure 5a, 5g )

Comments

This species seems to occur in the areas where hygrophilous steppe is present, together with Hyparrhenia bracteata (Poaceae) , Sorghastrum scaberrimum (Poaceae) , and some species of Paspalum (Poaceae) , feeding on flowers and seeds of these species. The humid areas are located in the lower altitudes and plateaus of the GSP, near Atlantic Forest, being a transition area between Cerrado and the aforementioned biome ( IAP 2002).

Bioacoustics ( Figure 6a–b )

Males sing during the day and at sunset. Duration of pulses: 15.6 ± 0.83 ms (13.35–17 ms); duration of echemes: 1.63 ± 0.19 s (1.13– 1.8 s); mute interval between echemes: 22 ± 5.7 s (14–31 s); bandwidth: 16 ± 1.3 kHz (14–20 kHz); peak frequency: 16.7 ± 2.3 kHz (11.6– 23.2 kHz).
