Gomphocerus (Bolivarianus) hemipterus Karabağ, 1953 stat.n.

Material: Male specimens collected from Turkey, Ordu, between Yeşilce-Çambaşı plateau, N 40.622778, E 37.965000, 1841 m, 04.vii.2013, (leg. A. Mol & D. Sirin) and male calling song recorded from three males in the field and laboratory (or room) conditions by A. Mol & D. Sirin.

Description of male calling song: Four records from three males were examined. Calling song consists of a phrase lasting 44–60 s and is composed of about 90–155 syllables ( Fig. 4D ). The phrase begins quietly and crescendo structure and is reached the maximum intensity at the 55–65 syllables (1/2 of the phrase) and lasting 8–10 low amplitude isolated syllables ( Fig. 4D ). Each syllable (RPU) lasts in 410–455 ms. Oscillographic analysis shows that a syllable consists of two different parts ( Fig 4E and 4F ). The syllable begins with low-amplitude (with unified indistinct pulses without gap) which last 195–218 ms and the second part of the syllable (last in 198–220 ms) includes higher amplitude distinguishable 9–11 pulses.
