Description. Male (holotype). Body medium stout, subparallel. Head: rostrum moderately stout, medium long (l/ w 4.40, Rl/Pl 1.33), black, very close to apex blackish; in lateral view slightly evenly curved, same width from base to antennal insertion, beyond antennal insertion moderately tapered to apex, at antennal insertion slightly widened; in dorsal view very slightly broadened from base to apex, at base moderately laterally constricted, in distal part moderately flattened dorsoventrally; basal part until antennal insertion very densely to confluent longitudinally punctured, apical part with well separated subelongate punctures, at apex glabrous, shiny; basal part covered with recumbent, moderately elongate yellowish-gray scales, apical part with suberect, long, whitish seta-like scales. Head between eyes relatively broad, of about 0.6 rostrum width at base. Eyes rounded, not protruding from head outline. Antennae reddish brown with darkened club, inserted at 0.7 of rostrum length; funicle of about 2/3 of scape length, segment 1 wider and somewhat shorter than segment 2, more than twice as long as wide, segments 3–4 slightly longer than wide, segment 5 subquadrate; club elongate, about 3.2 × as long as wide, of approximately same length as funicle, densely covered with recumbent, dark brown, thin long setae and sparse strongly erect, long whitish sensilla. Pronotum: black, somewhat wider than long (Pl/Pw 0.65), with very densely arranged but clearly separated small subrotund punctures, covered with recumbent to subrecumbent elongate (l/w 3–5), yellowish scales being densely arranged on pronotum sides, anterior and posterior margin, and midline; widest at base, with almost parallel sides in its basal half, then conically narrowed to anterior margin, slightly convex on disc. Prosternum: anterior margin with marked, sharply deep incised emargination not reaching coxae. Scutellum: black, subtriangular, with blunt apex, covered with sparsely distributed, subrecumbent, elongate, backwardly oriented, yellowish scales. Elytra: dark brown with black base, slightly rounded, somewhat elongate (El/Ew 1.36), widest at about half of their length, at base markedly wider than pronotum (Ew/Pw 1.71), humeri moderately prominent, rounded, with shallow posthumeral impression; very slightly convex to flat on disc; interstria 1 moderately broadened at about 1/3 of medial length encompassing black tomentous, unclearly bounded, small round macula with scattered yellowish scales, interstria 1 markedly elevated in apical part of elytra, here without macula; odd interstriae approximately as wide as even ones, with evenly distributed dark tomentous, subquadrate to round spots; striae shallow with only indistinct punctures divided by thin, tiny transverse septa; entire integument except tomentous maculation covered with recumbent to subrecumbent, backwardly oriented elongate (l/w 3–5), yellowish scales leaving integument partially visible. Venter: sparsely covered with recumbent, elongate scales, more densely arranged at apex of ventrite 5, metepisternum with dense yellowish scales; mesosternal process very short, blunt; metasternum moderately concave, sparsely finely punctured; ventrite 1 with deep medial impression, in middle of impression with longitudinal broad carina disappearing posteriorly, ventrite 2 with shallow flat impression with sparse fine punctation; ventrite 1 1.4 × as long as ventrite 2, ventrites 1–2 combined 3.0 × as long as ventrites 3–4 combined, ventrites 3–4 combined of 0.9 length of ventrite 5. Legs: femora black, tibiae, tarsomeres 1–3 and distal part of onychia blackish-brown, proximal part of onychia and claws reddish-brown; profemora with small blunt teeth, meso- and metafemora with large sharp teeth; femora, tibiae, tarsomeres 1–3 relatively densely covered with recumbent to subrecumbent elongate yellowish scales, onychia with sparsely distributed, suberect whitish setae; onychia of anterior legs very long, of about 1.1 length of tarsomeres 1–3 combined; protarsal lateral claws of about half length of medial ones, meso- and metatarsal medial claws by about 1/3 shorter than their pair-claws. Penis: Figs 14 d–f, its body very large and long, in lateral view sinuate, in basal part parallel, then tapered to apex.

Female. Rostrum slightly longer (Rl/Pl 1.37), elytra broader (El/Ew 1.33) than in male. Ventrites 1–2 without impression. Onychia of anterior legs short, of about 0.75 length of tarsomeres 1–3 combined. Claws almost equally long.

Variability. Length: ♂♂ 4.35–4.60 mm, ♀♀ 4.58–4.80 mm. The type series does not show remarkable vari- ability. The elytral integument is black in some specimens. The onychia may be almost completely blackish-brown to reddish-brown (especially in females).

Diagnosis. This species is easily recognizable by slender body, apical elevation of elytral interstria 1, elongate antennal club, missing apical elytral spot in both sexes, and typical medial longitudinal carina in impression on ventrite 1 in male.

Comparative notes. This species is most closely related to C. subalpinus , from which it differs by slender body, markedly elongate antennal club, missing apical elytral spot, marked elevation of apical part of elytral interstria 1, elytral pattern and carina in impression on ventrite 1 in males.

Biological notes. The type series was collected on Scrophularia sp. before its flowering period. Specimens were sitting in terminals and at the leaf insertions of the upper parts of the plant.

Distribution. Armenia.

Etymology. This species was dedicated to the first author´s deceased father Dr. Doděk Košťál, who awoke and developed his interest in natural sciences.

Non-type specimens examined. None.
