DESCRIPTION. Medium sized subspecies ( Figs 27–34 View Figs 27–34 ). GBL = 21.0– 26.3 mm, males 21.0– 23.2 mm, females 22.5–

26.3 mm, SBL = 19.2–23.3 mm in both sexes. Underside black, dorsum with metallic luster similar both in males and females, head black, pronotum black on disk, lateral sides with metallic coloration, elytra with bright metallic green or bronze luster, legs, antennae, and mandibles black, with faint brownish tint. Head not inflated, with nearly equal length and width, HL = 3.0– 3.7 mm in males, 3.3–4.3 mm in females, HW = 3.4–3.7 mm in males, 3.5–4.8 mm in females; neck punctate, surface with coarse rugosity near eyes; mandibles elongate; antennae reaching one-third to middle of elytra. Pronotum nearly rectangular, sides with very faint sinuation before base, PW = 3.4–3.7 mm in males, 4.5–6.1 mm in females, PB = 3.5–4.0 mm in males, 3.3–4.5 mm in females, PL = 3.2–3.9 mm in males, 3.5–4.1 mm in females, PW/HW = 1.2–1.5 in both sexes, PW/PL = 1.3–1.6 in both sexes, PW/ PB = 1.2–1.4 in both sexes; hind angles faintly protruding posteriorly; disk completely punctate, punctation more coarse at sides and base. Legs moderately long. Elytra faintly convex, ovate, somewhat elongate, EW/PW = 1.4–1.9 in both sexes; EL = 12.0– 13.5 mm in males, 12.9–15.6 mm in females, EW = 3.44. 4 mm in males, 3.5–4.8 mm in females, EL/EW = 1.4–1.8 in both sexes; elytral sculpture pronounced, 3 rows of impressions are distinguishable, these punctures regularly covering entire elytral surface.

Aedeagus faintly bent basally, apical lamella hardly protruding ( Figs 35–37 View Figs 35–39 ). Endophallus with strongly developed mediolateral and ventroapical lobes, basiolateral and dorsoapical lobes less prominent, aggonoporius small.

DIFFERENTIAL DIAGNOSIS AND REMARKS.A new subspecies reliably differs from C. kasakorum in the male genitalia structure. It is distinguishable from the other known subspecies of C. nothus by constantly brighter dorsal coloration, not characteristic for them. From the most close morphologically subspecies C. nothus daghestanicola it differs also in more depressed elytra and fainter protruding posteriorly hind angles of pronotum.

DISTRIBUTION AND HABITAT. A new subspecies populates mountain masses of Skalistyi Mt. Range in the interfluve of Argun and Sharoargun rivers, it inhabits meadows at 1200 –2400 m and prefers stony sites. The adults are active from the end of May, beginning with the snow melting. Following Carabus forms occur together with this subspecies: C. (Pachycarabus) staehlini Adams, 1817 , C. (Tomocarabus) convexus Fabricius, 1775 , C. (Sphodristocarabus) adamsi Adams, 1817 , C. (Cechenochilus) boeberi Adams, 1817 , C. (Tribax) osseticus Adams, 1817 , C. (Eu-

carabus) cumanus Fischer von Waldheim, 1823 , C. (Megodonthus) exaratus Quensel, 1806 , and C. (Procrustes) clypeatus Adams, 1817 .

ETYMOLOGY. The subspecific epithet refers to the name Sharoy, indicating both historical geographic and administrative district of Chechen Republic, and one of 9 Chechen tukhums and taips.
