Poecilimon davisi Karabag, 1953   (davisi -group)

TURKEY: Isparta, Dedegöl Mt. , 1700–1800 m (37.69437ºN, 31.29401ºE), 14.06.2014, nymphs last instar and imago, leg. D. Chobanov & S. Kaya GoogleMaps   , several males recorded ( Fig. 7 View FIGURE 7 , 8 View FIGURE 8 ), stridulatory file studied; Adana, Madenli vill., 1700 m (37. 32325ºN, 31. 83269ºE), 15.06.214, nymphs, leg. D. Chobanov & S. Kaya; Isparta, GoogleMaps   Sultan Dagh near Aksehir , 1900 m (38.2833°’N, 31.3167°E), 28.06.2002, leg. K.-G. Heller, 2 males GoogleMaps   recorded; Isparta, Yalvaç (38.2667°N, 31.1667°E), 28.06.2002, leg. K.-G. Heller, 2 males GoogleMaps   recorded.

The males were active at night and produced short echemes with a duration of 0.4± 0.1 s (n=54; range 0.25– 0.63 s; Fig. 8 View FIGURE 8 ). During the recording sessions always at least two males were in acoustical contact. In this situation the echemes were often arranged in groups with two or more males alternating. However, occasionally also isolated echemes were heard (duration of intervals 3.9± 8.1s, range 0.2–47s, n=45). An echeme contained on average 9 syllables (SRR 20.2 Hz; T =25–26ºC). The syllables had a duration of 30.6±3.8 ms (n=13) and contained 5.1±1.1 (n=13) impulses ( Fig. 7 View FIGURE 7 ) resulting in a mean interval of 7.8 ms between the impulses. Sometimes intrasyllable gaps were as large as the gaps between the syllables. At 20ºC the SRR was only 15.3 Hz and the syllables had a duration of about 40.6±3.9 ms (n=9).

The spectrum of the song had its peak near 30 kHz ( Fig. 9 View FIGURE 9 ).
