Neoconocephalus rioclarensis Piza, 1975

Fig. 6H ; 8H

Distribution: Brazil: Minas Gerais, Paraná, São Paulo.

New record for the Paraná State.

Comments: Individuals of this species were found only at night, and we are able to locate them specially when they were singing. Males are quite large when comparing to another species of Neoconocephalus , presenting the tegmina with conspicuous black spots. This species is also polymorphic, since green and testaceous individuals are present.

Bioacoustics ( Fig. 7A–D ): The song of the species was recorded in an amplitude above the limit of the recorder, but we were still able to infer some characteristics. Males emit regularly spaced echemes, during the night, each echeme composed by ca. 25 hemisyllables. The amplitude is constant.

Dominant frequency: 5.4 ± 0.2 kHz.

Bandwidth: 0.9 ± 0.5 kHz.

Duration: Echeme: 0.2 ± 0.007 s.

Mute interval: Echeme: 1.5 ± 0.003 s.
