Chorthippus (Glyptobothrus) maritimus Mistshenko, 1951

References to song. Bukhvalova (1993, 1998): recordings from the Crimea, the southern regions of European Russia, the North Caucasus, South Turkmenistan, South Kazakhstan, Amur Oblast, and Primorskiy Kray; Benediktov (2005): recordings from Irkutsk Oblast; Savitsky & Lekarev (2007): 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, b): recordings from Saratov Oblast, Eastern Siberia, and Primorskiy Kray. The main part of the calling song is an echeme lasting from 3 up to 10 s.

Song. The song begins quietly reaching maximum intensity in first 2–4 s. In 1.5–4 s after the end of the main part male usually produces 1–3 shorter echemes with more abrupt beginning (Figs. 47–50). The second half of each syllable usually has higher amplitude and includes 2–4 gaps (Figs. 51–60). A syllable repetition period averages 100–160 ms in our recordings.

Comparative notes. G. maritimus is a most common gomphocerine species in all regions of Kyrgyzstan from the arid foothills up to about 2000 m above sea level. Signals of different males somewhat vary in an echeme duration and a syllable shape but all these differences are within the variation range observed in other regions. Thus, in acoustic traits males from the mountains of Kyrgyzstan do not differ from the ones from European Russia, South Siberia, and the Russian Far East. [1]
