Body bright green, occasionally apex of crown with black spot. Forewings hyaline or weakly infumose ( Fig. 13 ). Abdominal apodemes of 2nd tergite in male more or less rounded, distinctly bent inwards and separated by broad round notch (Figs. 125–127). Sternal apodemes slender, almost parallel-sided or narrow triangular, separated by broad U-shaped notch (Figs. 128–130). Pygofer processes with tips slightly bent forward (Figs. 137–139). Penis in side view comparatively narrow with only slight if any extension at bend (Figs. 131–133). Styles of typical shape (Figs. 134–136). 2nd valvulae of ovipositor with 4+3 or 4+4 preapical teeth each (Figs.140–141). Body length (including tegmina): ♂, 4.1–4.4 mm; ♀, 4.6–5.1 mm. Nymph olive-green, almost hairless, with darker thorax and end of abdomen ( Fig. 14 ). Diagnosis . Belongs to the group of willow-dwelling uniformly green cryptic species. Differs from all other Central Asian members of this group by slender sternal apodemes separated by a broad U-shaped notch. In addition, distinguishable from M. abdullaevi Dubovskiy, 1966 , M. ibragimovi Dubovskiy, 1966 , and M. asiatica Dubovskiy, 1966 by more narrow penis stem in lateral view, larger size and host specialization. Differs from M. iliensis Mityaev, 1971 and M. tarbagataica Mityaev, 1971 by longer abdominal apodemes of 2nd tergite. Very similar to M. ocellata Provancher, 1872 dwelling on the same host, but can be distinguished from latter by almost parallel-sided sternal apodemes (strongly convergent in M. ocellata ). Totally different from all green willowdwelling Macropsis species from Russia , Kazakhstan and Central Asia in the temporal pattern of calling signals. Host. Salix alba (section Salix ).

FIGURES 155–168. 155–163― Macropsis tienschanica sp. n. , oscillograms of male calling signals; 164–168― M. elaeagnicola Dubovsky , same. Faster oscillograms of the parts of signals indicated as “159–163” and “166–168” are given under the same numbers. Calling signal. Signal is a succession of phrases lasting from 2–4 up to 7–8 s each ( Figs. 155–163 ). Typically the phrase includes one or two low-amplitude syllables, one high-amplitude one and several discrete highamplitude pulses repeated with a period 1– 1.5 s ( Figs. 155–157, 159–162 ). Occasionally, it reduces to highamplitude syllable and one or two pulses ( Figs. 158, 163 ). Males usually sing unceasingly for several minutes. Distribution. West Tien Shan Mts.: foothills of Chatkal Mtn. Range ( Kyrgyzstan ). S. alba is a common ornamental willow in Kyrgyzstan . However, up to now M. tienschanica was found on it only in the type locality. Etymology. The new species name derives from the name of Tien Shan Mtn. System.
