Remarks. Eodorcadion intermedium is a very variable species that is distributed in the southern part of Mongolia, and most likely also in China (Inner Mongolia) (Danilevsky 2007). The species currently includes two subspecies. The boundary of their range runs approx. along the meridian 103° east. Populations westwards from that line belong to the nominative subspecies. Nonetheless, a status of several local populations, which can be regarded as subspecies, requires further studies (Danilevsky 2007).

The nominative subspecies was discussed in our previous paper (Karpiński, Szczepański, Boldgiv et al. 2018).
