Material examined.

Almaty Region: 2 km N of Kegen [ Қеғен] (43°02'N, 79°13'E), 1809 m a.s.l., 12 VI 2017, 7♂♂, leg. WTS; 3♂♂, leg. LK; 4♂♂, leg. MW.


Dorcadion arietinum  includes seven described subspecies that are distributed in southern and southeastern Kazakhstan and northwestern China. The nominotypical subspecies is known to occur only in the area of SE Kazakhstan ( Danilevsky 2018a). It inhabits mountain valleys and semi-arid areas at altitudes of approx. 600-2000 m a.s.l. The larvae feed on the roots of various grass Poaceae  (e.g. Stipa  spp.) and sedges of the Cyperaceae  species. The adults feed on the aboveground parts of their host plants ( Toropov and Milko 2013).

The males (Fig. 13C) were collected in a mountain steppe habitat sympatrically with Dorcadion crassipes crassipes  Ballion, 1878 and Dorcadion semenovi semenovi  Ganglbauer, 1884. Although the plot (Fig. 13D) was mainly covered with high tufts of grass, there were also large, bare sandy spots where reddish and rather active beetles were clearly visible.
