Description
3. Omocestus haemorrhoidalis (Charpentier, 1825)
Figs. 10–12
Distribution. Transpalaearctic.
Locality. 8. Eastern shore of the Issyk-Kul’ (Ysyk Köl) Lake, 20 km West of Mikhailovka Village, dry glades in the thickets of sea buckthorn, 21. VII. 2014. Signals of 1 ♂ recorded on disk at 35o C.
References to song. Ragge & Reynolds (1998): recordings from Western Europe; Savitsky (2005): recordings from the Lower Volga Region and Western Kazakhstan (Janybek, ca. 5 km from the Russia border); Savitsky (2009): recordings from Western Kazakhstan (Janybek, ca. 5 km from the Russia border); Tishechkin & Bukhvalova (2009a): recordings from Saratov Oblast, Eastern Siberia, and Primorskiy Kray; Iorgu & Iorgu (2011): recordings from Romania.
Song. The calling song is a single or regularly repeated echeme lasting about 3–4 s and consisting of syllables following each other with a period of about 35–60 ms in our recordings (Figs. 10–11). Each echeme begins quietly and reaches maximum intensity in the second half or near the end. A syllable repetition period gradually increases towards the end of an echeme (Tishechkin & Bukhvalova, 2009b, fig. 83). Typically, syllables do not include distinct gaps (Fig. 12).
Comparative notes. O. haemorrhoidalis is one of the most thoroughly studied gomphocerine species; presently, there are signal recordings from many localities in Europe including European Russia, Western Kazakhstan (Janybek, ca. 5 km from the Russia border), Siberia, and the Russian Far East. Throughout many thousands kilometres of its range the song pattern remains remarkably constant both in general structure and in a syllable repetition period (Tishechkin & Bukhvalova, 2009a, b). Songs of the male from Kyrgyzstan do not differ from these of males from other regions.
