Hexacentrus karnyi Griffini 1909
Description
Hexacentrus karnyi Griffini, 1909
[A] CH 4982 ♂
The song of this species (two males recorded in the field at night) was in its basic structure (Fig. 15) similar to that of the Asiatic species H. unicolor Serville, 1831 (Heller, 1986) and other Hexacentrus species (e.g., Ichikawa et al. 2006), but it is much slower in echeme and syllable repetition rate. It consisted of a series of echemes, repeated at intervals of 8–12 s (0.5 s in H. unicolor). The syllable repetition rate was around 50 Hz (T=21ºC), again much slower than H. unicolor, which heats up before singing and reaches more than 300 Hz. Each echeme (duration about 0.7 s) started with a distinct impulse, probably indicating the opening of the tegmina. Similar isolated impulses can be seen in the song of the other species, but usually shortly after an echeme and produced during a final wing closure. The peak of the spectrum was situated at 9.7 kHz, close to that of 11 kHz observed in H. unicolor (Heller, 1986).
