Various representatives of this subgenus have already been discussed in the thread devoted, it seems, to the classification and definition of loci, so this topic is just an addition. The subgenus includes large and beautiful beetles. In the fauna of Russia (according to the updated list of ZIN) - 5 species: vietinghoffi, violaceus, aurolimbatus, exaratus, septemcarinatus.

Megodontus violaceus adrzejuscii, Fisch. 1823-Zap. Ukraine, Ivano-Frankivsk region, roc. Kosova, 17-27. VII. 2000
The beetle is distributed mainly in Europe, up to the western regions of Russia, in forests. Very changeable.

I looked up the taxonomy of the Carabus violaceus taxon in the Deuve catalog (also French, by the way). The layout is as follows-60 subspecies!!!

I won't list it, it will take up a lot of space. The main mass of subspecies is Europe.
However, in the preface to the catalog in the section "taxonomy", he says that there are the main generally accepted ("strong") subspecies-they are highlighted. The rest - as if secondary ("weak"). bicinctus is a secondary subspecies, purpurascens is a primary subspecies.Thus, the spelling of this taxon will be-Carabus (Megodontus) violaceus ssp. purpurascens F., 1787, however, indicates that if desired (in relation to this case), you can use this option - Carabus (Megodontus) violaceus (purpurascens) bicinctus Born, 1905 This absolutely does not contradict the international code (ICZN). So choose the option you like!

Pre-Urals and the Urals, in Zap. It is sporadic in Siberia, Novosibirsk, Tomsk, Kemerovo regions, Altai Krai, Tuva, Krasnoyarsk Krai, and the Baikal Region.
Mainly in mountain forests in a large range of heights, sometimes reaching the subalpine. Rare. Shellfish feeding was noted (Shilenkov V. G.©)
According to the latest list of ground beetles in Russia, this species is included in the subgenus Pachycranion. This subgenus is absent from well-known foreign catalogues of the genus Carabus. Several color forms of the view are described. Ab. melanchlorus (pronotum and elytra edging are black), ab. gouberti (elytra edges are golden green), ab. chakassicus (elytra are chocolate brown with dark blue edging).

Alexander, do these forms have a clear geographical distinction? Or can they run together?
