Distribution. P. grandis is endemic to Anatolia. It was recorded only from Antalya province of Turkey (Figure 9A) (Karabağ 1952; Karabağ 1958; Çıplak 2000; Ünal 2018).
Song recording. Male specimens collected from Turkey, Antalya, İbradı, between İbradı-Kuyucak road, 37°08.55’ N, 031°37.03’ E, 1260 m, 06.VII.2015 (by D. Şirin, M.S. Taylan & A. Mol) and calling song recorded from two males at 26–27 °C in the field (by D. Şirin & M.S. Taylan).
Description of song. Four records from two males were examined. The calling song consists of a series of regular phrases (Figure 9B) with an interval of 1.251–5.700 ms (2.983 ± 0.98). Phrase durations vary between 407–466 ms (439.6 ± 17.36) and phrases consist of 7–9 (8.12 ± 0.45) syllables. Generally, the first and second syllables at the beginning of the phrase are quieter and shorter (having low amplitudes) than the following syllables (Figure 9C). Syllables period duration varies between 49 and 67 ms (57.74 ± 3.58) without an interval. Oscillographic analyses show that each syllable contains two parts (except first syllable) (Figure 9D). First part of the syllable is relatively shorter and quieter than the second part of the syllable (Figure 9D). First part of the syllable lasts for 14–18 ms (15.71 ± 1.32) and is followed by a second part after an interval of 0–3 ms (1.42 ± 0.42). The second part of syllable is much louder (except of the first syllable) and longer than the first part; its duration varies between 28–44 ms (33.51 ± 3.77) and includes 22–36 (28.18 ± 3.12) pulses (Figure 9D).
