New record for the Paraná State.

Comments: This species is also remarkably abundant and is syntopic with Ceraia cornutoides . The individuals are collected both in light traps as during active search both at night and day. The occurrence of this species seems to be restricted to areas southwards of the Tropic of Capricorn.

Bandwidth: 3.7 ± 1.1 kHz.

Duration: Syllable: 0.08 ± 0.03 s.
