Male Stridulatory file: The stridulatory file (Figs. 11–14) is long (min. 2.917– max. 3.940 mm), bearing more than 200 teeth (min. 186- max. 235, n= 6), which gradually widen towards the middle and gradually narrow towards the apex. The shape of medial teeth as in Fig. 14. Bioacoustics: The songs of 10 male bush-crickets were recorded in the evening and at night. Totally, 30 syllables belonging to six males were measured. Male calling songs were produced mainly in the evening and night at laboratory (t= 25–27°C) and consisted of irregular sequences of isolated syllables (Fig. 16). The syllables were repeated at about 7.075.79 (mean ±SD, min. 2.09, max. 29.67), lasted about 0.6690.062 s (min. 0.452, max. 0.740) and composed of 118.639.73 impulses. The amplitude of the impulses increased at first part (including average 66.639.08 impulses, duration: 0.3220.06) and decreased towards the end (average impulse number 48.2310.79, duration: 0.3230.067) (Figs. 17A; 18A–B). The impulses were formed in a wider range in the last part of the syllable (Fig. 17B). The peak frequencies of both crescendo and decrescendo parts of the syllable were similar (24.932.89, 24.823.19 kHz, respectively).
