Type locality. – Georgia, Lesser Caucasus , Borjomi-Kharagauli National Park, 959 m a.s.l., 41°44'51.756''N / 43°10'36.48''E GoogleMaps .

Differential diagnosis. – Idolus caucasicus sp. n. resembles Idolus adrastoides Reitter, 1888 in general shape but can be separated by its larger size, shinier pronotum, shorter antennae, narrower dorsal stripe on the elytra, finer and more regular pubescence of the body, the regularly rounded apex of the ninth sternite and differences in the sclerites of the bursa copulatrix and aedeagus.

Description of the holotype ( Fig. 1)

Coloration. – Body elongate; head, pronotum, scutellum, meso-, metasternum and abdomen black to black-brown with reddish shadings at the anterior angles of pronotum and parts of prosternum and hypomeron; elytra light brown, darkened at base of elytra,scutellum and along the suture and at the lateral margins; dorsal stripe confined to the first interstria, diffusing into the second in the middle of elytra; legs yellowish brown; antennae dark brown, first three antennomeres reddish yellow; maxillary and labial palps yellowish brown; entire body covered with fine and recumbent pubescence, head and pronotum with light yellow, elytra with yellow and rusty-yellow pubescence.

Frons. – Convex; anterior margin arcuate, directed downwards, nearly touching the clypeus in the middle; punctuation dense, punctures umbilicate with shiny intervals, smaller than their diameters.

Antennae. – Exceeding by a half antennomere the apices of the posterior angles of pronotum; second antennomere sub-cylindrical, third antennomere sub-conical, almost subequal in length, the third is barely visible shorter than the second, taken together 1.5 times longer than fourth, very slightly serrated from the fourth antennomere on, the last antennomeres nearly with sub-parallel sides.

Pronotum. – As long as wide, widest at the apices of the posterior angles; moderately convex, with a short shallow mid-longitudinal depression at the basal slope; sides narrowed anteriorly, sub-parallel in the middle; posterior angles long, slightly divergent, unicarinate; carina sharp; pronotal lateral margins complete, almost fully visible in a dorsal view (not visible near anterior angles); punctuation moderate dense; punctures slightly umbilicate with variable intervals, equal to their diameters to smaller; interstices on disc shiny ( Fig. 5); smooth and shiny areas at the lateral slope.

Scutellum. – Tongue-shaped, long as wide, flat to slightly convex, with straight frontal margin, slightly sinuate at the sides; punctured, interstices with weakly wrinkled surface.

Elytra. – 2.86x longer than pronotum, 2.58x longer than wide, moderately convex, sides sub-parallel from the base to almost the middle, then gradually tapering to the apices, the latter truncate and weakly dentate; striae regularly distinct punctured, larger intervals towards the apices; interstriae flat, finely punctured.

9th sternite. – Long as wide; lateral sides from half gradually narrowed toward apex, apically rounded (Fig. 7) (length 0.8 mm).

Aedeagus. – As in Fig. 9 (length 0.7 mm).
