Figs. 21 , 102–106 , 112–115

Description. Bright green or yellowish green, occasionally, with black frontal spot ( Fig. 21 ).

Abdominal apodemes of 2 nd tergite in male comparatively long and narrow, with sinuate inner margins; sternal apodemes narrow triangular, separated by wide rounded notch ( Figs. 102, 104 ). Penis in side view rather narrow, tapered evenly to apex ( Figs. 103, 105 ). 2 nd valvulae of ovipositor with 3–5 preapical teeth ( Fig. 106 ).

Body length (including tegmina): ♂, 4.2–4.6 mm; ♀, 4.7–5.5 mm.

Specimens from European Russia ( Figs. 102–103 ) and Southeastern Kazakhstan ( Figs. 104–106 ) have no significant differences in shape of apodemes and genitalia.

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

1. Crimea , environs of Pereval’noe Village halfway from Simferopol to Alushta, from Salix alba , 16–17. VI. 1997, calling signals of 3 males recorded at 22–25 oC .

2. Southeastern European Russia, Saratov Oblast, 15 km southwest of Khvalynsk Town, environs of Ulyanino Village, from S. alba and S. euxina , 15–17. VI. 1996, signals of 5 males recorded at 22 and 31 oC.

3. Southeastern European Russia, Volgograd Oblast, Ilovlya River about 5–7 km from the mouth (ca. 4 km southwest from Ilovlya Town ), from S. alba . 8. VI. 1996, calling signals of 3 males recorded at 20–26 oC .

4. Southeastern Kazakhstan, the floodplain of Lepsy River near its exit from the foothills of Dzhungarsky Alatau Mtn. Range to the plain (13 km south of Kolbay Village), from S. alba , 18–19. VI. 2019, signals of 4 males recorded at 26–28 oC .

5. Southeastern Kazakhstan, Karakol River 27 km south of Taskesken Village in the western part of Tarbagatai Mtn. Range, from S. alba , 24. VI. 2019, signals of 1 male recorded at 25 oC .

Calling signal consists of short phrases following each other with a period from 1.5 up to 10 s and consisting of two or three syllables each. Amplitude relation of syllables can vary, but typically the syllable 2 nd from the end of a phrase has the highest amplitude. Signals of males from European Russia and Kazakhstan are almost identical ( Figs. 112–115 ).

Host. Salix alba and S. euxina in European Russia, S. alba in Kazakhstan.

Distribution. Europe, southern half of European Russia and adjacent regions of Northwestern Kazakhstan, Southeastern Kazakhstan (new record).
