description: Macropsis iliensis Mityaev, 1971
Figs. 11–12, 86–124
Description. Body light green, forewings hyaline or slightly infumose, darkest in apical parts, in males darker than in females. Dorsal part of abdomen usually more or less darkened, black abdominal terga visible through forewings (Fig. 11).
Abdominal apodemes of 2nd tergite in male short, rounded, separated by broad notch (Figs. 86–88, 101, 108). Sternal apodemes strongly convergent, with wide bases and slightly expanded rounded tips almost touching each other and separated by narrow gap (Figs. 89–91, 102–103, 109).
Pygofer processes with tips distinctly bent forward (Figs. 97–99, 106). Penis in side view usually rather short and wide (Figs. 92, 104, 110), occasionally narrow (Fig. 93). Styles of typical shape (Figs. 94–96, 105). 2nd valvulae of ovipositor with 2–4 preapical teeth each (Figs. 100, 107, 111).
FIGURES 86–111. Macropsis iliensis Mityaev. 86–88, 101, 108―male abdominal apodemes of the 2nd tergite; 89–91, 102–103, 109―the 2nd sternite; 92–93, 104, 110―penis, lateral view; 94–96, 105―end of style; 97–99, 106―pygofer process, lateral view; 100, 107, 111―the 2nd valvulae of ovipositor. 86–100―specimens from Jumgal River Valley, No. 8 on the map; 101–107― paratypes from South-Eastern Kazakhstan; 108–111―specimens from South Urals, Russia.
Body length (including tegmina): ♂, 3.8–4.3 mm; ♀, 4.4–5.0 mm.
Nymph pale green, pubescent with white setae (Fig. 12).
Differs from other willow-dwelling Central-Asiatic green Macropsis species by the strongly convergent sternal apodemes. Temporal pattern of calling signals is also distinctive.
Host. In Kyrgyzstan is abundant on Salix turanica (section Vimen), in Russia (South Urals) only several specimens were collected on S. vinogradovii (section Helix).
Calling signal. Signal is a single or repeated phrase lasting from 10–15 up to 30–40 s (Figs. 112–118). The phrase consists of a prolonged trill of partially merged pulses (the initial one third of oscillograms on Figs. 120–123) followed by 2–5 discrete syllables (last two thirds of oscillograms on Figs. 120–123). The appearance of a trill on oscillograms varies greatly due to irregular amplitude modulations. Occasionally males produce only a long succession of discrete syllables, i. e. prolonged second part of a phrase (Figs. 119, 124).
Material examined. 8― Kyrgyzstan, Jumgal River Valley in the environs of Baisak Town, Salix turanica, 1. VII. 2013, D. Tishechkin, 45 ♂, 36 ♀, 10 nymphs, calling signals of 6 ♂ recorded on disk at 23 and 28o C (ZMMU; Figs. 86–100, 112–113, 115–117, 120–122).
Additional material. Paratypes from Southern Kazakhstan with the labels "Iliysk railway station, at light, 9. VI. 1964, G. Rustambekova" (ZMMU; Figs. 101–107); Russia, South Urals, Orenburg Area, the bank of Guberlya River near Guberlya railway station, 25 km West of Orsk, S. vinogradovii, 5. VII. 1996, D. Tishechkin, calling signals of 1 ♂ recorded on tape at 23–24o C (ZMMU; Figs. 108–111, 114, 118–119, 123–124).
Distribution. There are reliable records of this species from South Urals (Tishechkin, 2002), from several localities in the plains of Northern, Central and Southern Kazakhstan, from Karatau Mtn. Range, Southern Kazakhstan and from Inner Tien Shan Mts., Kyrgyzstan (new record). Apparently, it occurs from extreme southeast of European Russia (South Urals) throughout Kazakhstan to the mountains of Central Asia.
Remarks. This species was described in brief terms in the key to species of Macropsis of Kazakhstan (Mityaev, 1971). Identification of the species is based on investigation of the paratype series.
