Green or yellowish green, forewings semitransparent ( Fig. 3 ). Aedeagal shaft with widened lobe-like apex laterally ( Fig. 16 ). Gonopore subapical, with two basal processes. Style with asymmetrical apophysis strongly bent outwards ( Fig. 17 ). Body length (including tegmina): ♂ , 3.7–4.1 mm; ♀ , 4.8–5.2 mm. Hosts. In steppes and semi-deserts, on Agropyron spp. Calling signal. Signals of seven males from the environs of Altynemel Village , 45 km east of Zharkent along the road to Saryozek , Southern Kazakhstan were recorded on 11. VI. 2019 at 22 oC . Calling signal has a duration of about 7–15 s and is a succession of syllables following each other with a period of 1– 1.5 s ( Figs. 40–42 ). Each syllable begins with a succession of short pulses repeating at a rate of about 70–80/s in our recordings ( Figs. 54–57 ). Then 5–8 longer pulses repeating at a rate of about 20–25/s follow. Pulses are often merged with each other and are partially indistinguishable. Distribution. Described from Southern European Russia , Sarepta, presently, environs of Volgograd , Lower Volga Region ( Fieber, 1885 ). Widespread in steppes and semi-deserts of Southeastern Europe, Kazakhstan , and Central Asia.
