Yalvaciana yalvaci ( Demirsoy, 1974) View in CoL
Distribution. Y. yalvaci is endemic to Anatolia. It was only recorded from Erzurum provinces of Turkey ( Figure 20A View FIGURE 20 ) ( Demirsoy 1974; Ragge 1990; Çıplak et al. 2002).
Song recording. Male specimens were collected from Turkey, Erzurum, Palandöken Mountains, ascent moun- tain road, fountain side, 39°51.03’ N, 041°16.40’ E, 2347 m, 22.VIII.2015 (by D. Şirin, M.S. Taylan & A. Mol) and calling song recorded from two males at 29°C in the laboratory (by D. Şirin & M.S. Taylan).
Description of song. Eight records from two males were examined. The calling song has a relatively complex signal structure and its durations vary between 2.74– 3.98 s (3.43 ± 0.72). Oscillographic analyses show that male calling consists of two different sections ( Figure 20B View FIGURE 20 ). The Section I has two isolated shorter phrases (rarely three) and its duration varies between 132–164 ms (144.14 ± 6.28) with an interval of 704–885 ms (825.25 ± 18.76). This section includes two different parts. First part of the section consists of 4–6 syllables, which have crescendo structure. The syllables period in this part lasts for 15–19 ms (17.72 ± 1.18). The second part of section I lasts for 48–69 ms (59.50 ± 3.76) and includes 24–34 (27.15 ± 2.78) distinct pulses ( Figure 20C View FIGURE 20 ). The Section II consists of a series of long phrases and its duration varies between 1.23– 1.78 s (1.44 ± 0.28). This section includes 12–15 (13.85 ± 0.52) syllables without intervals. The first part in the beginning of Section II has a similar structure with the Section I. The following syllables have specific structure and their periods last 89–104 ms (97.65 ± 3.22) without any intervals ( Figure 20D View FIGURE 20 ). Each syllable in this group includes two elements (quieter and louder) ( Figure 20D View FIGURE 20 ). First element of a syllable is a quieter (also shorter) part and its duration varies between 6 and 11 ms (8.10 ± 1.22). The first element of syllable is followed by a louder (also longer) part without any interval; its duration varies between 78 and 94 (89.24 ± 3.08) and includes 38–49 (44.05 ± 2.82) pulses.
