Figs. 23 , 122–138

Description. Bright green, forewings sometimes slightly infumose, especially, in males ( Fig. 23 ).

Abdominal apodemes of 2 nd tergite in male more or less rounded, separated by round notch ( Figs. 126, 130, 134 ). Sternal apodemes rather long, strongly convergent, as a rule, with more or less expanded tips usually overlapping with each other in males from Kyrgyzstan and Tajikistan ( Figs. 127–128 ) and only touching each other or separated by narrow gap in males from Kazakhstan ( Figs. 131–132, 135–136 ). Penis in side view comparatively wide, with only slight if any extension at bend ( Figs. 129, 133, 137 ). 2 nd valvulae of ovipositor with 2–4 preapical teeth each ( Fig. 138 ).

Body length (including tegmina): ♂, 3.4–3.8 mm; ♀, 4.2–4.6 mm.

Calling signals. Signals of males from the following localities were investigated.

1. Kyrgyzstan, Alay Mtn. Range, Kurshab River 10 km north of Gul’cha Village, from Salix alba , 5. VII. 2014, signals of 6 males recorded at 26–29 oC .

2. Kyrgyzstan, Turkestan Mtn. Range, Lyaylyak River , environs of Katran Village, from S. alba , 12. VII. 2014, signals of 3 males recorded at 31 oC .

3. Kyrgyzstan, eastern slope of Ferghana Mtn. Range, Urumbash River ca. 15 km southwest of Kazarman Town, from S. alba , 17. VII. 2014, signals of 3 males recorded at 29 oC .

4. Kyrgyzstan, Chatkal Mtn. Range, Ala-Buka River , environs of Ala-Buka Village, from S. alba , 20. VIII. 2011, signals of 1 male recorded at 22–23 oC .

5. Southern Kazakhstan, Charyn River near the bridge 35 km northwest from Kegen, from Salix michelsonii , 9–10. VI. 2019, signals of 3 males recorded at 23–26 oC .

6. Southeastern Kazakhstan, Karakol River 27 km south of Taskesken Village in the western part of Tarbagatai Mtn. Range, from Salix sect. Helix , 24. VI. 2019, signals of 7 males recorded at 25–28 and 33–34 oC.

Signal consists of prolonged phrases lasting from 20–30 s up to 1–2 min each ( Figs. 122–125 ). Each phrase includes two parts. The first part is a succession of syllables following against a background of constant low-amplitude vibrations. The second part is a high-amplitude fragment sounding like a monotonous buzz. Occasionally the second part is divided by gaps into several fragments. Often the first part is more or less reduced. Signals of males from Kyrgyzstan and Kazakhstan are similar, which testifies to their conspecificity.

Host. Salix alba in Kyrgyzstan, Salix spp. from the section Helix in Kazakhstan.

Distribution. Was recently described from Central Asia (several localities in Kyrgyzstan and Tajikistan); proved to be widespread in Southern and Southeastern Kazakhstan (new records).
