Remarks.

Politodorcadion eurygyne is distributed in eastern Kazakhstan and West Siberia. This species includes two subspecies: P. e. eurygyne and P. e. lailanum Danilevsky, 2007 (Danilevsky 2018a). The nominotypical subspecies occurs in two separate regions in E Kazakhstan: north of Lake Zaysan and to the south of the Tarbagatay Mountains. Its range in the latter area is limited only to southern foothills of the Kalbinsky Ridge (Danilevsky 2007b). The beetles inhabit clayey deserts and semi-deserts (at an altitude of approx. 500 m a.s.l.) with sparse grass vegetation where they feed on various species of Poaceae (Toropov and Milko 2013).
