14. Rhoananus hypochlorus (Fieber, 1869) Figs 59–63. MATERIAL. Kyrgyzstan, Inner Tien Shan Mts., steppe on the northern bank of the Western Karakol River, ca 25 km eastnortheast of the Suusamyr Village, 13.VII.2023, signals of two males recorded at 24 °C. SIGNALS. The male calling signal consists of short syllables following each other with irregular gaps from 1.5–2.0 up to 5.0– 10.0 s and more (Figs 59–60). Duration of syllable averages 400–520 ms (Figs 61–62). Pulse repetition period in the syllable increases from about 37–45 ms in the beginning to about 45–57 ms in the end. On oscillograms at high speed it is visible that the signal has a pure-tone carrier (Fig. 63). REMARKS. Pure-tone signals are quite typical for Paralimnini and have previously been recorded in 22 out of 59 studied species of this tribe [Tishechkin, Burlak, 2013].
