Figs. 36–37 , 190–195

Macropsis obscurinervis Vilbaste, 1965: 31–32 (synonymy by Tishechkin, 1994).

Description. Pale yellow with black pattern on head, pro-, and mesonotum ( Figs. 36–37 ). Forewings more or less infumose with dark veins. Male darker than female.

Abdominal apodemes of 2 nd tergite in male wide, rounded, separated by very narrow notch ( Figs. 190–191 ). Sternal apodemes narrow triangular, separated by U-shaped notch ( Fig. 192 ). Penis stem in side view narrow, usually, bent at almost right angle ( Figs. 193–194 ). 2 nd valvulae of ovipositor very wide, with one preapical tooth each ( Fig. 195 ).

Small species; body length (including tegmina): ♂, 3.2–3.4 mm; ♀, 3.4–3.9 mm.

Host. Spiraea hypericifolia in European Russia, Kazakhstan, and Central Asia, S. aquilegifolia and, possibly, some other Spiraea species in Transbaikalia.

Distribution. Steppe zone of Palearctic from European Russia to Eastern Transbaikalia and Mongolia. In Southeastern Kazakhstan is common in steppes in the plains and low mountains; the only Macropsis species abundant outside river valleys.

Remark. Identification of this species is based on investigation of type specimens from Troitskosavsk (presently Kyakhta Town), Southern Transbaikalia, deposited in ZIN.

Species feeding on Rosa and Hippophae rhamnoides are indistinguishable in the shape of the male abdominal apodemes and genitalia and in most cases are also similar in the shape the 2 nd valvulae of the ovipositor. At the same time, they distinctly differ from each other in coloration and can be easily identified by external appearance. For this reason, we give a description of apodemes and genitalia here and omit this section in the descriptions of species.

Abdominal apodemes of 2 nd tergite in male wide, rounded, separated by wide round notch, sternal apodemes narrow triangular, separated by U-shaped angular notch. Penis in side view narrow ( Figs. 196–197 ), bent at almost right angle. 2 nd valvulae of ovipositor with 4–8 preapical teeth each, only in M. pictipes (Horvath, 1904) with 10–13 preapical teeth each.
