Dorcadion gebleri   is distributed in eastern Kazakhstan and northwestern China. The species includes four subspecies: A. g. demimetrum   Danilevsky, 1996, A. g. gebleri   , A. g. lukhtanovi   Danilevsky, 1996 and A. g. takyr   Danilevsky, 1996. Most of them are endemic to E Kazakhstan; only the nominotypical form extends its range into China ( Danilevsky 2018a). This taxon mainly occurs on a small area around Lake Zaysan. The imagines are active rather early from the end of April to May, and sometimes even in June ( Danilevsky 1996a). According to Danilevsky (1996b), this is the largest representative of the entire Dorcadion   genus. The larvae feed on the roots of Achnatherium   spp., especially on A. splendens   . The adults feed on the above-ground parts of their host plants on which they also copulate ( Toropov and Milko 2013).

Several males and females (Fig. 13E) that were collected in May were observed in pasture habitats overgrown by high tufts of Festuca   sp. (Fig. 13F). The specimens that were found in mid-June consisted of rather old body remains, which confirms the very early period of the occurrence of this species. The plot was also overgrown by high tufts of Festuca   sp. The two males that were depicted (Fig. 6I, J) were collected in two different plots located approx. 100 km from each other.
