REMARKS. This subspecies is known to populate Skalistyi Mt. Range in the interfluve of Terek and Argun rivers, other subspecies of C. kasakorum substitute it westwards, C. nothus occurs eastwards of Argun valley ( Fig. 1 ). It inhabits alpine zone at 2200–2800 m and prefers stony hillside wastes, where population density is high, activity of adults starts with the snow melting.

C. kasakorum tschetschenicus is rather variable in body appearance and proportions in different populations (Table 1–2), individual populations are variable too, this appears in elytral sculpture intensity, pronotum and elytra proportions, and dorsum luster variations ranging from completely black to bright gold, bronze, or green.
