Eodorcadion dorcas dorcas (Jakovlev, 1901) Figs 3G, H , 11A

Material examined.

Govi-Altai Aimag: 20 km SSW of Bayan-Uul (46°51'N, 95°07'E), 1878 m a.s.l., 11 VIII 2015, 1♂, 2♀♀, leg. MW; 4♂♂, leg. LK.

Remarks.

This taxon is endemic to Mongolia and is distributed from the Khovd environs to the west and the southern parts Zavkhan Aimag and then to the northern part of Gobi-Altai Aimag ( Danilevsky 2007).

Only a few specimens were collected in the late afternoon in a small enclave (Fig. 11B ) with high tufts of grass Achnatherum splendens (Fig. 11C ) during rather cold (22 °C), cloudy and windy weather. The males (Fig. 11A ) were rather mobile, running and trying to hide in the tufts of grass. In this locality, the remains of several imagines were found (Fig. 11D ).
