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 ).
