Macropsis asiatica Dubovskiy, 1966

Figs. 84–113

Description. Body bright-green with yellowish tinge, forewings transparent with green veins.

Apodemes of 2nd abdominal sternite in male more elongate and slender than in two previous species, with strongly converging tips (Figs. 87–90). Tergal apodemes more or less rounded, with margins of irregular shape (Figs. 84–86).

Pygofer processes slightly bent forward (Figs. 94–95). Penis in side view rather short and broad, as in M. abdullaevi and M. ibragimovi (Figs. 91–93). Tips of styles usually somewhat blunt (Figs. 96–98). 2nd valvulae of ovipositor with 2+3 or 3+3 preapical teeth (Figs. 99–100).

Body length (including tegmina): ♂, 3.7–4.1 mm; ♀, 4.3–4.9 mm.

Nymph unknown.

M. abdullaevi and M. ibragimovi differ as noted in the last paragraphs of the descriptions of those species. Distinguishable from M. tarbagataica by wider penis stem in lateral view and paler forewings.

Host. Salix pycnostachya (section Helix ).

FIGURES 84 – 100. Macropsis asiatica Dubovskiy. 84–86―male abdominal apodemes of the 2nd tergite; 87–90― the 2nd sternite; 91–93―penis, lateral view; 94–95―pygofer process, lateral view; 96–98―end of style; 99–100―the 2nd valvulae of ovipositor.

Calling signal. Signal consists of phrases lasting ca. from 15 up to 30 s each ( Figs. 101–113 ). Each phrase begins with comparatively short succession of alternating simple and complex syllables (first halves of oscillograms on Figs. 107–112 ), followed by prolonged succession of only simple syllables. Pauses between phrases usually do not exceed 5–8 s. Male may sing unceasingly for several minutes.

Complex syllables in the beginning of the phrase are similar in temporal pattern with those of the middle part of the phrase in M. ibragimovi ( Figs. 78–83 ). However, in other traits the calling signals of the two species are quite different.

Material examined. 3—foothills of Chatkal Mtn. Range, Kara-Suu River Valley near Ak-Jol Village (5 km South-East from type locality), 12. VII. 2009, 7 ♂, 3 ♀, calling signals of 2 ♂ recorded on disk at 22o C. 5— Bekechal Ravine on the left bank of Lower Naryn River Valley, ca. 40 km downstream from Kara-Kul’, 5. VII. 2011, 3 ♂, 5 ♀, calling signals of 2 ♂ recorded on disk at 22o C.

Distribution. West Tien Shan Mts.: foothills and midlands of Chatkal and Ferghana Mtn. Ranges ( Kyrgyzstan). The range of the host plant includes West Tien Shan and Pamir-Alai Mtn. Systems.

Remarks. The type locality of M. asiatica, Jany-Jol Village , is situated in the Kara-Suu River Valley 5 km downstream of Ak-Jol, where part of my material was collected. The original description of this species is rather superficial, but fits my specimens.
