Literature data. Dornogovi: Khötöl-Us [ca. 43.450, 100.716] (type locality) (Jakovlev 1889; Danilevsky 2007); from Dalanzadgad to Tsagaan Ders, 3.08.1949, 11 ♂♂, 4 ♀♀, Eglon leg. (ZIN) ( Danilevsky 2007); Noyon ridge, 10 km N of Noyon [ca. 43.292, 102.108], 22– 23.08.1969, 1 ♂, Zaitzev leg. (JV) (ibid); 30 km W Tost-Uul ridge [ca. 43.142, 100.041], 8.08.1981, 2 ♂♂, 1 ♀, Lvovsky leg. (ZIN) (ibid).

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).
