Distribution. This interesting species is endemic to Anatolia. It was known from Niğde, Erzurum, Erzincan, Kahramanmaraş, Tunceli, Malatya and Sivas provinces of Turkey ( Figure 13A View FIGURE 13 ) ( Ramme 1951; Karabağ 1961; Sevgili et al. 2012).

Song recording. Male specimens collected from Turkey, Erzincan, Munzurlar, Doymuş, 07.VII.2007 (by H. Sevgili) and calling song recorded from one male at 27 °C in the laboratory (by H. Sevgili).

Description of song. Two records from one male were evaluated. The calling song consists of isolated phrases with an interval of 12.570– 25.780 s (19.120 ± 5.28). The phrases duration varies between 588–736 ms (631.25 ± 22.28) and consists of 11–13 (11.51 ± 0.29) syllables ( Figure 13B View FIGURE 13 ). The phrase begins with 4 lower amplitude syllables (these syllables show crescendo structure) and the remaining part of phrases consists of 4–5 double-syllables ( Figure 13C View FIGURE 13 ). The maximum intensity is usually reached between 1/3 of the phrase ( Figure 13B View FIGURE 13 ). Syllable duration varies between 21 and 30 ms (24.48 ± 1.95) with an interval of 14–22 ms (18.33 ± 2.05) in group (between syllables in couple) and 31–52 ms (29.16 ± 4.22) intergroup (between double-syllables). Oscillographic analyses show that syllables consist of several high amplitudes elements ( Figure 13D View FIGURE 13 ). These elements number are uncountable in the first syllable, 7–10 in the second syllable, 11–14 in the third syllable, 9–13 in the fourth syllable, and 13–20 in the following syllables.
