Uvarovistia zebra ( Uvarov, 1916)

Distribution. U. zebra is semi-endemic to Anatolia. It was recorded from Eastern Anatolia (Van, Hakkari), Leba- non, Iraq, Iran and Syria ( Figure 19A ) ( Ramme 1951; Karabağ 1958; Garai 2010; Ünal 2012; Gholami et al. 2015; Ünal 2018).

Song recording. Male specimens were collected from Turkey, Hakkari, Çukurca, Çukurca-Narlı village road, 2 km to Narlı village, 37°16.587’ N, 043°33.799’ E, 1271 m, 31.V.2018 (by M.S. Taylan & F. Yeşilyurt) and calling song recorded from two males at 27 °C in the laboratory (M.S. Taylan).

Description of song. Four records from two males were examined. The calling song consists of a series of short phrases (or isolated triple/quadruple syllables groups) with an interval of 1.44– 6.50 s (4.26 ± 1.64) ( Figure 19B ). Phrases durations vary between 168–298 ms (207.76 ± 10.78) and phrases consist of 3–4 syllables. The phrase usually begins with a low amplitude and a shorter syllable ( Figure 19C ). Syllables duration varies between 40 and 49 ms (44.76 ± 1.95) with an interval of 25–44 ms (30.14 ± 3.18). Oscillographic analyses show that each syllable contains two parts. First part of the syllable is relatively shorter and quieter than the second part of the syllable (except for the first syllable in the phrase) ( Figure 19D ). First part of the syllable lasts for 10–17 ms (14.24 ± 1.72) and is followed by a second part without intervals. The second part of the syllable is much louder (except for the first syllable at the beginning) and is longer than the first part; its duration varies between 21–34 ms (29.58 ± 3.54).
