Material examined. Holotype, ♂, Southeastern Kazakhstan, central part of Dzhungarsky Alatau Mtn. Range, river gorge east of Dzhansagurov Village , from Salix sect. Helix, D. Tishechkin , 14. VI. 2019, calling signals recorded at 29 oC; paratypes: same locality and date, 1 ♂, 5 ♀, male calling signals recorded at 29 oC; same locality, 15. VI. 2019, 9 ♂, 13 ♀, calling signals of 2 ♂ recorded at 22 oC; 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 Salix sect. Helix , 19. VI. 2017, 12 ♂, 7 ♀; same locality, 18. VI. 2019, 9 ♂, 9 ♀, calling signals of 2 ♂ recorded at 27 oC; same locality, 19. VI. 2019, 11 ♂, 10 ♀ ( ZMMU).

Description. Yellow or orange yellow, often with greenish tinge ( Figs. 26–28 ). Forewings hyaline or slightly infumose, dorsal part of abdomen usually more or less darkened, black abdominal terga visible through forewings.

Abdominal apodemes of 2 nd tergite in male short, separated by wide round notch, with inner margins concave or of irregular shape ( Figs. 165–167 ). Sternal apodemes with very wide strongly convergent lobes usually overlapping or at least touching each other and separated by small gap ( Figs. 168–171 ). Penis in side view comparatively wide, with distinct extension at bend ( Figs. 172–174 ). Pygofer processes with tips slightly bent forward ( Figs. 175–177 ). Styles of typical shape ( Figs. 178–179 ). 2 nd valvulae of ovipositor with 5–7 preapical teeth ( Figs. 180–182 ).

Body length (including tegmina): ♂, 3.6–4.1 mm; ♀, 4.0– 4.7 mm.

Diagnosis. Belongs to the group of Central Asian small willow-dwelling species. In external appearance differs from related species by yellow or orange yellow coloration. Also, differs from other species by very wide, strongly convergent and usually overlapping lobes of 2 nd sternal apodemes and larger number of preapical teeth on 2 nd valvulae of ovipositor (2–4 in most other Central Asian species).

In shape of sternal apodemes sometimes is similar to M. milkoi (cf. Figs. 131 and 171), but can be distinguished from it by coloration and larger number of preapical teeth on 2 nd valvulae.

Host. Salix spp. from the section Helix .

Calling signal. Calling signal is a phrase lasting from 4–5 up to 20–30 s ( Figs. 151–160 ). It begins with a low-amplitude monotonous vibrations lasting from 2–3 up to 10–15 s. Then several high-amplitude syllables each lasting from ca. 0.5 up to 4 s follow. Amplitude of vibrations within syllable is constant or slightly periodically fluctuates. The phrase ends with a short single pulse.

Distribution. Apparently, endemic to Dzhungarsky Alatau Mtn. Range.

Etymology. This species is named after Asel Lee (Karaoy, Kazakhstan) for her help, kindness, and hospitality during our visits to Kazakhstan.
