Figs 17–20, 25–28.

DISTRIBUTION. Natural range of this species includes eastern Transbaikalia, Mongolia, southern part of the Russian Far East, northern China, and Japan. Was introduced to Central Asia, Kazakhstan, South Urals, and the southern half of European Russia with ornamental Ulmus pumila L. [ Dmitriev, 1999, 2001; Anufriev, 2006b; Tishechkin, 2020b].

RECORD. Moscow Oblast, Voskresensk District , environs of Beloozerskiy Town, from cultivated U. pumila . First record in Moscow Oblast and the northernmost record in European Russia .

REMARKS. The discovery of M. illota in Moscow Oblast suggests further northward expansion of its range.

In the shape of abdominal apodemes and genitalia, males from Moscow Oblast are indistinguishable from males collected from wild-growing trees of U. pumila in Transbaikalia. Calling signals of 3 males from Moscow Oblast recorded on 25.VII.2021 at 22 ° C. Signal patterns in males from Moscow Oblast and Transbaikalia are almost identical ( Figs 25, 27 and 26, 28 ) .
