Remarks. Eodorcadion humerale impluviatum is endemic to Mongolia. In the southeastern part of the country, it is only known from a few localities (Fig. 4), while most of the sites are concentrated around Ulaanbaatar (Danilevsky 2007). We observed this taxon sympatrically with other Eodorcadion species, for instance with Eodorcadion oryx (Jakovlev, 1895), however, most of the adults of E. h. impluviatum were already dead. This subspecies was discussed in our previous paper (Karpiński, Szczepański, Boldgiv et al. 2018).
