Eurycorypha punctipennis ( Figs. 3 , and 4b)

The song of E. punctipennis consists of echemes containing two parts (see description in Hemp et al. 2013). The first was always softer and shorter (duration, 126 ± 16 ms; range, 108–168 ms; n = 3 males with 5 measurements each; T = 17–21 °C) with about 44–51 impulses, the second louder and longer (duration, 191 ± 20 ms, range 158–235 ms) containing around 60 impulses. Similar slight shifts of some frequency components in both parts support the idea that each of them is produced by one tegminal movement cycle and not during opening and closing (SRR, 5.3 Hz; syllable period, 187 ± 21 ms). Several (4.5 ± 2.8; n = 44) of these disyllabic echemes were combined to series and repeated at intervals of about 10–16 s. These echeme series were separated by intervals of several minutes up to hours .
