Material examined.

Bulgan Aimag, 20 km N of Ulaanshiveet, (47°37'N, 103°51'E), 1108 m a.s.l.; 19 VIII 2015: 6♂♂, 3♀♀, leg. MW; 3♂♂, 4♀♀, leg. WTS; 1♂, 4♀♀, leg. LK.

Remarks.

This subspecies is distributed in the eastern part of Mongolia from the western boundary of Khentey Aimag to the Chinese border ( Danilevsky 2007).

The adults are active at the turn of July and August. Danilevsky (2007) observed imagines of this species feeding on Caragana stems. This shrub has not been found in the presented locality.

In the late evening hours (about 8-9 p.m.), the specimens were collected during slightly windy weather from a habitat (pasture) that was mainly covered with low grass and herbs (Fig. 14H ). In this locality, most of the beetles were hidden under rocks and cow dung (Fig. 14G ).
