Macropsis populicola Dubovskiy, 1966: 92–93 (synonymy by Tishechkin, 2011).

Macropsis albinata Dubovskiy, 1966: 91–92 (synonymy by Tishechkin, 2014).

Macropsis albidula Dubovskiy, 1966: 92 (synonymy by Tishechkin, 2014).

Description. Pale greenish (specimens from old collections sometimes yellowish), usually with more or less developed black pattern on head, pro-, mesonotum, and forewings. In Central Asian populations, specimens with weakly developed pattern or without it prevail ( Figs. 8–9 ).

Abdominal apodemes of 2 nd tergite in male elongate, sometimes slightly bent inwards, broadly separated by an oval or U-shaped notch ( Figs. 55–56 ). Sternal apodemes strongly convergent, with wide bases and slightly expanded truncate or rounded tips usually touching each other or even slightly overlapped ( Figs. 57–58 ). Penis in side view wide, with distinct extension in middle ( Figs. 59–60 ). 2 nd valvulae of ovipositor normally with one preapical tooth each ( Fig. 61 ).

Body length (including tegmina): ♂, 4.0– 4.4 mm; ♀, 4.7–5.2 mm.

Host. Silver poplar ( Populus alba ).

Distribution. Temperate parts of Europe including European Russia (northwards at least as far as Moscow Oblast), Northern Caucasus, Kazakhstan, Central Asia, southern regions of Western Siberia. Introduced to North America ( Hamilton, 1980).

Widespread in Northeastern Kazakhstan, where wild Silver poplar grows. The southernmost known locality is the flood-plain of the Ayagoz River 45 km southwest of Ayagoz Town, ca. 50 km north of the boundary of the studied region. Can be found in Southeastern Kazakhstan on ornamental Silver poplar.
