Neoconocephalus sp. 5

Fig. 6N

Comments: Sixteen individuals were sampled, which presents: (1) the ventral region of all tibiae black, as well as the ventral region of the apical half of the femur III, (2) wide wings, with numerous black punctuations; (3) rhomboid fastigium of the vertex, much longer than wide, with a white apex, (4) apex of the fastigium of the vertex coloured as the rest of the body, with a black spot above the fastigium tooth, (5) quadrangular mirror, with all the margins slightly curved, lateral and medial margins much longer than the anterior and posterior margins.

Bioacoustics ( Fig. 7E–H ): Males stridulated during the night, in a long sequence of echemes (superior to seven minutes), that appear in a crescendo of amplitude. When each echeme was analysed, several hemisyllables, also in a crescendo of amplitude, appear. We also highlight that this echemes was regularly spaced. As hemisyllables, sound is just produced by the closing stroke.

Dominant frequency: 12.1 ± 0.8 kHz.

Bandwidth: 6.6 ± 1.2 kHz.

Duration: Syllable: 0.01 ± 0.006 s; Echeme: 1.8 ± 0.2 s.

Mute interval: Syllable: 0.006 ± 0.001; Echeme: 2.0 ± 0.2s.
