Poecilimon ataturki Ünal, 1999 (ampliatus -group)

TURKEY: Devrekani–Bozkurt road, 9.07.2011, 1200 m (41.70733ºN, 33.97399ºN), leg. B. Çıplak, S. Kaya & D. Chobanov, 1 male recorded .

P. aff. ataturki : Tokat, 10.07. 2011, 700 m (40.2661ºN, 36.5494ºN), leg. Chobanov

The calling song of the recorded male consisted of long series (at least 26 to 62 s) of up to 875 syllables. In one case two series were separated by a very short interval (<1 s). The syllables (duration 55 ms) were produced at a rate of 14.6 Hz ( Fig. 6 ) and contained about 20 impulses ( T =26.7–28.2ºC). Except of a very few cases they had always a gap in the middle ( Fig. 7 ) and the mean interval between the impulses was about 2.9 ms (gap included).

The stridulatory file carries 95 teeth (inter-tooth distance 31–38 µm) and is bi-partite by a distinct step in the middle of the file ( Fig. 5A ; Devrekani–Bozkurt). In this male the basal (proximal) part has 48 teeth and the anal (distal) 47, in a male from Tokat ( P. aff. ataturki ) the numbers are 34 and 36, respectively.
