Loginova, VI. 1975, 8 ♂, 6 ♀ ( ZIN ). Description. Body bright green, forewings transparent or weakly infumose, darkest in apical part, in male darker than in female. Abdominal apodemes of 2nd tergite in male more or less rounded, slightly bent inwards and separated by round notch (Figs. 1–4). Sternal apodemes rather long, strongly bent dorsally, with expanded tips usually overlapping with each other (Figs. 5–9). Penis in side view as a rule comparatively wide, with only slight if any extension at bend (Figs. 10–13). Pygofer processes with tips slightly bent forward (Figs. 14–16). Styles of typical shape (Figs. 17–19). 2nd valvulae of ovipositor with 2–4 preapical teeth each (Figs. 20–22). Body length (including tegmina): ♂, 3.4–3.8 mm ; ♀, 4.2–4.6 mm . Diagnosis . Belongs to the group of willow-dwelling uniformly green cryptic species. Very similar to M. iliensis Mityaev, 1971 , but can be distinguished from latter by the more strongly convergent sternal apodemes with overlapping tips (separated by narrow gap or only touching each other in M. iliensis , Figs. 226-229), smaller size (♂, 3.8–4.3 mm , ♀, 4.4–5.0 mm in M. iliensis ), and brighter coloration. Differs from all other Central Asian members of this group by 2nd sternal apodemes with tips overlapping or at least touching each other. Different from all green willow-dwelling Macropsis species from Russia , Kazakhstan and Central Asia in the temporal pattern of calling signals. Host. Salix alba (section Salix ). Calling signal. Signal consists of prolonged phrases lasting up to 1–2 min each ( Figs. 23–30 ). Each phrase includes two parts. The first part consists of a succession of syllables following against a background of constant low-amplitude vibrations ( Figs. 25, 28, 32–35 , first halves of oscillograms, and Fig. 31 ). The second part is a highamplitude trill sounding like a monotonous buzz ( Figs. 25, 28, 32–35 , second halves of oscillograms, and Fig. 37 ). Occasionally the second part is divided by gaps into several discrete fragments ( Figs. 24, 26, 30 ). Often the first part is more or less reduced ( Figs. 27, 29 ). Distribution. Chatkal, Ferghana, Alay, Turkestan and Hissar Mtn. Ranges. FIGURES 1–22. Macropsis milkoi sp. n. 1–4―male abdominal apodemes of the 2nd tergite; 5–9―the 2nd sternite; 10– 13―penis, lateral view; 14–16―pygofer process; 17–19―end of style; 20–22―2 nd valvulae of ovipositor. Etymology. This species is named after Dmitri Milko (Institute of Biology and Pedology, Bishkek, Kyrgyzstan ) for his invaluable help during our fieldwork in Kyrgyzstan .
