Poecilimon haydari Ramme, 1951 (armeniacus -group)

TURKEY: Niğde, Bolkar Mt., Maden Köyü, 1278 m (37.50763ºN, 34.59105ºE) & Kanagol Lake , 1950 m (37.45749ºN, 34.60315ºE), xeromesophyte grass associations, 17.06.2014, nymphs last instar and imago, leg. D. Chobanov, 1 male recorded ( Fig. 6 , 7 ), stridulatory file studied ; Niğde, Ulukısla , 24.06.2001, leg. H. Sevgili, 1 male recorded ; Niğde, Buldurus (pass in Ala Dagh ) (37.9667°N, 35.0167°E), 3.07.2002, leg. K.-G. Heller, 1 male recorded ; Konya, Kizkayasi Mts. , north of Konya, 1700 m (38.1333°N, 32.5167°E), 29.06.2002, leg. K.-G. Heller, 1 male recorded ; Konya, west of Konya (Erenkaya), Bulumya yaylasi, 1500 m (37.7332°N, 32.1332°E), 30.06.2002, leg. K.-G. Heller, 1 male recorded .

The song is quite similar to that of P. armeniacus . The males produced series with a quite variable duration of 20.0± 22.5 s (n=11; range 2.4–75 s) at intervals of 12.2±6.3 (n=3) s. A series contained on average 200 syllables (SRR 12.6 Hz; T =25–29ºC; Fig. 6 ). The syllables had a duration of 51.6±3 ms (n=7) and contained 5.6±0.7 (n=7) impulses, resulting in a mean interval of 10.4 ms between the impulses ( Fig. 7 ).

The spectrum of the song had its peak between 30 and 40 kHz ( Fig. 9 ; high pass filter 12 kHz)

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