Gomphocerus (Gomphocerus) eyluldenizi sp. n.

Material: Male specimens collected from Turkey, Erzurum, Palandöken Mountains , N 39.823889, E 41.291944, 2890 m., 22.viii.2015, and male calling song recorded from one male in the field and laboratory (or room) conditions by authors .

Description of male calling song: One record from a male was examined. Calling song consists of a phrase lasting 34.88 s and composed of about 81 syllables ( Fig. 5A ). The phrase begins quietly and reached the maximum intensity at the 20 syllables (1/4 of the phrase) ( Fig. 5A ). Oscillographic analysis show that each syllable (RPU) lasts in 415–482 ms and a syllable consists of the two different structural parts ( Figs. 5B and 5C ). The syllable contains two different structural pulses. The first part includes 9–11 low-amplitude distinguishable pulses (all of the last in 205–225 ms) which have gaps (8–13 ms) and the second part of the syllable (duration: 172–186 ms) includes higher amplitude distinguishable 10–11 distinct pulses without gaps ( Fig. 5C ).
