description: 4. Macropsis iliensis Mityaev, 1971
Figs. 11–16, 69–91
Macropsis tuvensis Vilbaste, 1980: 24–25. Syn. n.
Description. Green or pale green (Figs. 11–16). Forewings hyaline or slightly infumose, darkest in apical parts. Dorsal part of abdomen usually more or less darkened, black abdominal terga visible through forewings. Ends of tarsi often darkened. In males dark coloration is more developed than in females.
Abdominal apodemes of 2 nd tergite in male short, separated by broad notch (Figs. 73, 76, 79). Sternal apodemes strongly convergent, with wide bases and slightly expanded tips sometimes almost touching each other and separated by narrow gap (Figs. 69, 71, 73, 76, 79). Penis in side view wide, with only slight if any extension in middle (Figs. 70, 72, 74, 77, 80). 2 nd valvulae of ovipositor with 3–4 preapical teeth (Figs. 75, 78, 81).
Body length (including tegmina): ♂, 3.8–4.3 mm; ♀, 4.4–5.0 mm.
Calling signals. Signals of males from the following localities were investigated.
1. Guberlya River near Guberlya Railway Station, 25 km west of Orsk, Orenburg Oblast, Southern Urals, Russia, from Salix vinogradovii, 5. VII. 1996, signals of 1 male recorded at 23–24 oC.
2. Kyrgyzstan, Central Tien Shan Mts., Dzhumgal River Valley in the environs of Baizak Village, from S. turanica, 1. VII. 2013, signals of 6 males recorded at 23 and 28 oC.
3. Kyrgyzstan, Eastern slope of Ferghana Mtn. Range, Urumbash River ca. 15 km South-West from Kazarman Town, from S. turanica, 18. VII. 2014, signals of 4 males recorded at 31 oC.
4. Southeastern Kazakhstan, Karakol River 27 km south of Taskesken Village in the western part of Tarbagatai Mtn. Range, from S. turanica, 24. VI. 2019, signals of 1 male recorded at 25 oC.
Calling signal is a single or repeated phrase lasting from 10–15 up to 30–40 s and consisting of two parts differing from each other in temporal pattern and frequency spectra (Figs. 82–85). The first part is a succession of syllables variable in length and following against the background of a continuous low-amplitude vibrations; pulse repetition rate in syllables averages 70–90/s (Figs. 86–88). The second part includes 2–6 discrete syllables each ending with abrupt amplitude outbreak and consisting of short uniform pulses; pulse repetition rate in syllables of the second part is much higher and averages 150–200/s (Figs. 89–91).
Host. In Kazakhstan and Central Asia was found on Salix turanica (section Viminella); in Russia (Southern Urals) one series of specimens was collected on S. vinogradovii (section Helix).
Distribution. The whole territory of Kazakhstan, mountains of Central Asia (North and Central Tien Shan); reaches Southern Urals, Russia in the extreme northwest of the range and Southern Siberia (Tyva) and Western Mongolia in the extreme northeast. In Kazakhstan and Kyrgyzstan was found on almost all investigated plants of S. turanica.
Remarks. Identification of M. iliensis is based on investigation of the type series from Southern Kazakhstan (Figs. 69–70), with the label “Iliysk Railway Station [now in its place is the Kapchagai Reservoir], at light, 9.VI.1964. G. Rustambekova” (our comments in square brackets), deposited in the collection of ZMMU.
Identification of M. tuvensis is based on reinvestigation of two paratype specimens from Kaa-Khem near Kyzyl, Tyva, Southern Siberia (Figs. 71–72), deposited in the Institute of Zoology and Botany of Academy of Sciences of Estonia, Tartu.
Specimens from Kyrgyzstan, Kazakhstan, Tyva, and Mongolia are similar in shape of male apodemes and genitalia and in a number of preapical teeth on 2 nd valvulae of ovipositor (Figs. 69–81). Still, specimens from Kyrgyzstan and Southern Kazakhstan usually have somewhat brighter coloration (Fig. 12) and/or lighter tarsi tips (Fig. 11). However, in males from Southeastern Kazakhstan coloration is typical of M. tuvensis from Tyva and Mongolia (Figs. 13 and 15), but calling signal pattern is the same as in M. iliensis from Russia and Kyrgyzstan (82–91). For this reason, we establish the synonymy M. iliensis Mityaev, 1971 = M. tuvensis Vilbaste, 1980, syn. n.
