Poecilimon excisus Karabag, 1950 (armeniacus -group)

TURKEY: Eskisehir, Sivrihisar , 06.07.2003, leg. H. Sevgili ; Isparta, Sultan Dagh near Aksehir , 1900 m (38.2833°N, 31.3167°E), 28.06.2002, leg. K.-G. Heller, 2 males recorded ( Fig. 7 , 8 ), stridulatory file studied ; Konya, Aksehir (38.35°N, 31.4833°E), 29.06.2002, leg. K.-G. Heller, 2 males recorded .

The males produced short echemes with a duration of 0.44± 0.14 s (n=56; range 0.2– 0.79 s; Fig. 8 ). During the recording sessions the singing males were usually in acoustical contact. The intervals between the echemes had a duration of 2.9± 2.0 s (range 0.9– 9.8 s, n=51). An echeme contained on average 6 syllables (SRR 12.6 Hz; T =25–30ºC). The syllables had a duration of 56.5±4.1 ms and contained 14.3±1.8 (n=12) impulses ( Fig. 7 ) resulting in a mean interval of 4.4 ms between the impulses.

For details of the stridulatory file see Table 2 , Fig. 5.
