Eodorcadion (Humerodorcadion) humerale humerale (Gebler, 1823)

Literature data. Sükhbaatar: Khadatyn-Bulag, 60 km N from Bayanterem [ca. 47.671, 112.464], 950 m a.s.l., 31.07.1965, 1 ♂, exp. Dr. Z. Kaszab (HNHM) (Heyrovský 1967b; Danilevsky 2007).

Remarks. Eodorcadion humerale, a widespread species, which includes five subspecies (Danilevsky & Lin 2012b), is distributed in Russia, between Transbaikalia and the Pacific Ocean in the Primorsky region, in the central and north-eastern territories of Mongolia, and in north-eastern China. According to Danilevsky (2020), the nominative subspecies is known from East Siberia, northeastern China (Heilongjiang and Inner Mongolia), and easternmost Mongolia (it was mistakenly given as limited to the territory of Mongolia in Karpiński, Szczepański, Boldgiv et al. (2018), instead of E. h. impluviatum).

Based on the morphology of the endophallic structures (Danilevsky et al. 2004), this species together with Eodorcadion lutshniki (Plavilstshikov, 1937) are the only representatives of the subgenus Humerodorcadion Danilevsky, Kasatkin & Rubenian, 2005 .
