Gomphocerus (Gomphocerus) turcicus Mistshenko, 1951 stat. n. et sp. rev.

Material: Male specimens collected from Turkey, Niğde, Ulukışla, Bolkar Mountains, 01.viii.2021, 2544 m., N: 37.416297, E: 34.553538, (leg. A. Mol, H. Sevgili, D. Şirin & M.S. Taylan) and male calling song recorded from two males in the field and laboratory conditions by authors .

Description of male calling song: Three records from two males were examined. The calling song consists of a phrase which last in 30.8–34.6 s. Bioacoustics analyses show that a phrase is composed of totally 100–108 syllables (first 80–86 syllables are contiguous without gaps and last 20–22 syllables are isolated (gaps: 200–220 ms) (Fig. 6A). The phrase begins quietly and crescendo structure and is reached the maximum intensity at the 40–45 syllables (2/5 of the phrase) and lasting 20–22 short and isolated syllables (Fig. 6A). Each syllable (RPU) lasts in 215–317 ms. Oscillographic analysis shows that a syllable consists of two different parts (Fig. 6B) in the first part of the phrase. The syllable begins with low-amplitude pulses which last for 95–102 ms and the second part of syllable has a high amplitude structure and last for 120–155 ms (Fig. 6C). At the end of the phrase (the last 20–22 relatively short and isolated syllables), syllables last for 82–105 ms with gaps (180–220 ms) and each syllable includes 6–9 distinct elements (Fig. 6C).
