Distribution. P. guichardi is endemic to Anatolia. It was recorded only from Trabzon and Giresun provinces of Turkey (Figure 12A) (Karabağ 1961; Ünal 2012).
Song recording. Male specimens collected from Turkey, Giresun, Tamdere, 40°30.24’ N, 038°21.09’ E, 1692 m, 17.VIII.2015 (by D. Şirin, M.S. Taylan & A. Mol) and calling song recorded from one male at 23–24 °C in the field (by D. Şirin & M.S. Taylan).
Description of song. Four records from one male were evaluated. The calling song consists of a series of regular phrases (Figure 12B) with an interval of 2.570– 3.780 s (3.120 ± 0.28). The phrases duration varies between 756–884 ms (802.48 ± 9.81) and consisting of 9–10 (9.81 ± 0.09) syllables. The phrase begins with 2 low amplitude and shorter syllables (first one is the shortest) and the maximum intensity is usually reached between 1/5 of the phrase (Figure 12C). The first 1–3 syllables at the beginning of the phrase usually include a pulse like quieter part, which lasts for 9–16 ms (13.02 ± 1.78). Syllable duration varies between 37 and 64 ms (56.25 ± 4.28) with an interval of 21–35 ms (26.18 ± 1.87). Oscillographic analyses show that the syllables consist of several high amplitudes elements (Figure 12D). These elements number are 4–7 in the first syllable, 7–10 in the second syllable, and 17–22 (generally 19–20) in the following syllables.
