Large form, body size 34.5-43.0 mm, males 34.5-39.0 (37.6) mm, females 37.2-43.0 (40.6) mm long. Underside black, dorsum bright bronze, red-gold, green, violet, dark blue, black, with metallic lustre in males and matte in females. Appendages black, rarely the femora are red and basal antennomeres reddish-brown (approx. 5 % of individuals). Body usually monochromatic dorsally, less frequently bicolored (head and pronotum being usually greenish, the elytra bronze or reddish-bronze). Body massive and rather high.
Head huge, somewhat inflated. Pronotum transverse to subquadrate, hind angles protruding backwards and in some individuals sidewards. PW/PL = 1,18-1,55 (1,37) in males and 1,29-1,67 (1,45) in females. Elytra faintly elongate, ovate; more elongate, sometimes with depression in the middle in females, EL/EW = 1,52-1,92 (1,72); generally more ovate, convex, and smoothed in males, EL/EW = 1,42-1,78 (1,59). Elytral sculpture precise to homodynamous and confused, with hardly any distinguishable primary interspaces in males. Male genitalia practically identical to other taxa of C. (A.) besleticus (I.Solodovnikov et all., 2014).
Populates boreal slopes of Bzybian Mt. Range on the right bank of River Reshevie (= Reshava) at 700-1000 m. Occurs sympatrically with C. (A). pseudopshuensis, the population density of the latter being somewhat higher. Occurrence of this subspecies at the left bank of River Reshevie and downstream River Bzyb seems also possible, but collected material does not confirm this possibility at present.
Prefers slightly sloping beech and fir-beech forest sites rich in ground litter on karstic landforms. Activity of imago proceeds from April to July. Carabus (Archiplectes) pseudopshuensis, C. (Tribax) apschuanus apschuanus, C. (Tribax) constantinovi otcharensis, C. (Tribax) circassicus circassicus (natio abasinus), С. (Microplectes) argonautarum reischitzi, С. (Megodontus) septemcarinatus, C. (Sphodristocarabus) armeniacus dvorschaki, and C. (Procerus) caucasicus colchicus occur together with this subspecies (I.Solodovnikov et all., 2014).
