Diagnosis. Frontoclypeal region and vertex with very fine and sparse puncturation; pronotum subrectangular, sides strongly rounded in anterior third and very weakly convergent in posterior third; in males metaventrite with trapezoidal median impression; metaventral process about 1/3 of maximum metaventral width, posteromesal margin slightly concave; lateral projections nearly as long as broad; aedeagus in ventral view with slender, subtriangular and pointed apex.

Description. Male. Body length 1.28–1.34 mm, moderately convex, head and pronotum brown with reddish hue, elytra dark brown, antennae and legs light brown, tarsi and mouth parts yellowish, mandibles with black apices, setation yellowish.

Head broadest across moderately small eyes; length 0.14–0.16 mm, width 0.26–0.29 mm; frontoclypeal region subtrapezoidal, slightly convex; vertex slightly convex; supraantennal tubercles slightly raised. Frontoclypeal region and vertex with very fine and sparse puncturation; setation moderately long, sparse, suberect. Length of antennae 0.48–0.54 mm; antennomeres I–II subcylindrical, 1.4 times as long as broad, III–IV slightly longer than broad, V elongate, 1.2 times as long as broad, VI slightly longer than broad, VII elongate, 1.2 times as long as broad, larger than V, VIII subtrapezoidal, IX transverse, 1.2 times as broad as long, X transverse, 1.4 times as broad as long, XI subconical, 1.5 times as long as broad.

Pronotum subrectangular, slightly convex, widest slightly anterior to middle, length 0.39–0.41 mm, width 0.46–0.50 mm, with broadly rounded anterior margin, posterior margin weakly biemarginate; sides strongly rounded in anterior third and very weakly convergent in posterior third. Lateral carina well-marked, microserrate, posterior corners almost right. Puncturation very fine, moderately dense, composed of small and shallow punctures; setation moderately long, suberect to erect.

Elytra oval, elongate, moderately convex, length 0.73–0.79 mm, width 0.51–0.55 mm, EI 1.39–1.45; widest at middle; apical margins of elytra almost straight. Each elytron with small single basal fovea located in middle between humerus and scutellum; humeral carina as long as 1/8 of elytral length. Puncturation relatively fine, moderately dense, punctures shallow, distance between punctures 1.0–2.5 times of their diameter. Setation moderately long, suberect to erect.

Metaventrite with median trapezoidal impression, weakly punctured, distance between punctures 0.5–1.0 times of their diameter, with moderately short and sparse setation; metaventral process as broad as 1/3 of maximum metaventral width, posteromesal margin slightly concave; lateral projections nearly as long as broad, apex of each forming sharp angle with pointed tip.

Aedeagus ( Figs. 14–15 ) length 0.42–0.44 mm, in ventral view with slender, subtriangular and pointed apex; each paramere slender with long apical seta; endophallus as in Fig. 16 .

Legs moderately long and slender; protibiae as in Fig.17 .

Female. Very similar to male, except metaventrite which is in middle slighty convex; body length 1.27–1.30 mm; head length 0.15–0.17 mm, width 0.27–0.29 mm; length of antennae 0.49–0.51 mm; pronotum length 0.37–0.39 mm, width 0.48–0.51 mm; length of elytra 0.72–0.74 mm, width of elytra 0.51–0.53 mm; EI 1.40–1.45.

Distribution. Serbia, Macedonia, Bulgaria and Greece.

Etymology. Species dedicated to Stanislav Vít, a specialist on Scydmaeninae and a collector of the type material.

Remarks. The new species is similar to C. assingi sp. n., but it can be distinguished by the following combination of characters: 1) the body is longer, 2) the antennae are much longer, 3) in males the metaventrite has a median trapezoidal impression, while in C. assingi the metaventrite is in the middle with a shallow oval impression, and 4) a different structure of the aedeagus.
