Macropsis tarbagataica Mitjaev, 1971

Figs. 12–13 , 114–151

Description. Body bright-green, forewings transparent with green veins, sometimes more or less smoky-coloured with widely lightened costal area in male ( Figs. 12–13 ).

Apodemes of 2nd abdominal sternite in male approximately triangular, occasionally with more or less prominent projections on inner margins at base (Figs. 117–119, 128, 131, 135). Tergal apodemes of same shape as in three previous species (Figs. 114–116, 134).

Pygofer processes almost straight, with tips slightly bent forward (Figs. 122–123). Penis in side view more narrow than in other species considered (Figs. 120–121, 129, 132). Styles usually with somewhat elongate and pointed tips (Figs. 124–126, 130, 133, 137). 2nd valvulae of ovipositor with 4 preapical teeth (Fig. 127).

Body length (including tegmina): ♂, 3.8–4.3 mm; ♀, 4.6–5.0 mm.

Nymph bright green, in body shape similar to those of M. abdullaevi and M. ibragimovi .

Host. Specimens were collected from Salix sp. (section Helix ) and S. alba australior (section Salix ) in Ferghana Mtn. Range, from S. tenuijulis (section Helix ) in Southern Kazakhstan (Zailiyskiy Alatau Mtn. Range near Almaty) and from S. viminalis (section Vimen ) in South Urals.

Calling signal. Calling signal is phrase consisting of two different parts ( Figs. 138–151 ). First one is sequence of trills with pulse repetition period 20–40 ms; duration of trill typically varies from 1–2 to 10–15 s. Usually successions of low-amplitude pulses are visible on oscillograms in gaps between trills ( Figs. 144, 147, 151 ). Second part of signal is succession of pulses repeated with period 100–250 ms. Additional low-amplitude pulses usually present between main ones in beginning of succession. In signals of males from Ferghana Mtn. Range second part consists only of 2–4 pulses ( Figs. 138–140, 145–146 ) or is entirely absent ( Fig. 141 ), whereas in males from South-Eastern Kazakhstan and South Urals it lasts from 3–4 to 10–15 s ( Figs. 142–143, 149–150 ).

Material examined. 6—Ferghana Mtn. Range, Arslanbob Town, bank of Arstanbap River, single tree of Salix sp. (section Helix ) and single tree of S. alba australior (= S. excelsa ) near small bog around brook, 13. VII. 2011, 4 ♂, 4 ♀, calling signals of 4 ♂ recorded on disk at 22–24o C.

Additional material. Paratypes from South-Eastern Kazakhstan with the labels "Semipalatinsk Area, Urdzharsk District, mouth of Urdzharka River. 15.VI.1963. I. Mityaev" (Figs. 134–137); Kazakhstan, environs of Almaty, S. tenuijulis near brook, 5.VII.1994, calling signals of 4 ♂ recorded on tape at 29o C (Figs. 128–130, 142, 148–149); Russia, South Urals, Orenburg Area, the bank of Guberlya River near Guberlya railway station, 25 km West of Orsk, S. viminalis , 6.VII.1996, calling signals of 2 ♂ recorded on tape at 25–27o C (Figs. 131–133, 143, 150–151).

Conspecificity of individuals from different localities is verified by calling signal analysis.

Macropsis tarbagataica Mitjaev. 114–116, 134―male abdominal apodemes of 2nd tergite; 117–119, 128, 131, 135―the 2nd sternite; 120–121, 129, 132―penis, lateral view; 122–123―pygofer process, lateral view; 124–126, 130, 133, 137―end of style; 127―the 2nd valvulae of ovipositor. 114–127―males from Arslanbob, No. 6 on the map; 128– 130―male from the environs of Almaty, Southern Kazakhstan; 131–133―male from South Urals, Russia; 134–137― paratype from South-Eastern Kazakhstan, Semipalatinsk Area.

Distribution. There are reliable records of this species from several localities in South-Eastern Kazakhstan, from South Urals (Tishechkin, 2002) and from West Tien Shan Mts. (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.
