Remarks. Eodorcadion zichyi is endemic to Mongolia. All its known localities are localised in Dornogovi aimag, mainly in the environs of Hovsgol ( Danilevsky 2007). The locality near Khoer-Dzan seems to require some confirmation as it has not been mapped in the Danilevsky’s revision, and it is the only one that slightly stands out from the compact range of this species more to the west.

This is one of the latest occuring Eodorcadion species in Mongolia —according to Danilevsky (2007) imagines emerge only in the first quarter of August, when the activity period of most other species is over or has been going on. A huge series of this species was collected by this author on 9–10 August 2002. Such an exceptionally late occurrence seems to be also confirmed by our own observations made in the last quarter of July in the type locality; we have not found even first single males in any of several suitable sites despite that other late Eodorcadion species , such as E. gorbunovi and E. intermedium were already active.
