Eodorcadion maurum australe Danilevsky, 2014 Figs 3I , 4A , 10F, G

Material examined.

Khovd Aimag: 20 km NW of Zereg (47°23'N, 92°28'E), 1158 m a.s.l., 14 VIII 2015, 10♂♂, 2♀ (1♀ dead - remains), leg. LK; 21♂♂, leg. MW; 14♂♂, leg. WTS .

Remarks.

This is a recently described subspecies that is distributed in the northern and central parts of Khovd Aimag. All previously known specimens were collected from end of June to July ( Danilevsky 2014b). Two other taxa occur in Mongolia: E. m. katharinae Reitter, 1898 and E. m. maurum Jakovlev, 1889 ( Danilevsky 2017c).

Before noon, during rather windy and cold weather, nearly 50 individuals were observed on the border of tall and short grass meadows (Fig. 10H ). The population was dominated by males (Fig. 10F ); the only living female (Fig. 10G ) was collected in the afternoon at the end of our stay at this locality. The males behaved rather apathetically, hiding and still drying from the morning dew in the grass. The females are likely to have been more active later than males when the weather conditions had improved. The remains of approx. ten males and one female were also found in the grass.
