Endemic for Turkey - North East Anatolia, East Anatolia (Figure 14a) ( Karabağ 1952, 1958, Ünal 2006).

Song recording.

Male specimens collected from Turkey, Erzincan, Kelkit-Pöske yolu, Ahmetli çıkışı, 2016 m, 30.VI.2013, 39°53.392'N, 39°21.588'E, (by D. Şirin, A. Mol & M.S. Taylan) and calling song recorded from two males at 28 °C in the field (by D. Şirin).

Description of song.

Totally six records from two males were examined. The calling song includes isolated syllables (Figure 14b, c) separated by intervals of 456-1915 ms (833 ± 0.25). Syllable duration varies between 62 and 90 ms (78.83 ± 4.68). Oscillographic analyses showed that each syllable includes generally two elements (quieter and louder) (Figure 14d). First element of a syllable (rarely absent) is a quieter part and its duration varies between 5 and 6 ms (5.77 ± 0.19). The first element of syllable is followed by a louder part with an interval of 4-6 ms (5.27 ± 0.62). The louder part (second element) of syllable consists of 24-32 (27.63 ± 3.13) pulses and its duration lasts from 48 to 56 ms (51.21 ± 2.14). Sometimes the louder part is followed by another quieter part with an interval of 13-19 ms (16.03 ± 2.24) and duration of 4-8 ms (5.20 ± 0.72) (Figure 14c).
