Diagnosis. Frontoclypeal region and vertex slightly convex; pronotum subrectangular; in males metaventrite with oval median impression, wealky punctured, metaventral process as broad as 1/3 of maximum metaventral width, posteromesal margin straight; aedeagus in ventral view with abruptly narrowing, elongate subtrapezoidal and blunt apical part.
Description. Male. Body length 1.32–1.34 mm, moderately convex, brown with reddish hue, legs and antennae light brown, tarsi and mouth parts yellowish, mandibles dark-brown with black apices, setation yellowish.
Head broadest across moderately small eyes; length 0.14–0.15 mm, width 0.25–0.27 mm; frontoclypeal region subtrapezoidal, slightly convex; vertex slightly convex; supraantennal tubercles slightly raised. Puncturation on frontoclypeal region and vertex very sparse, well-marked; setation moderately long, very sparse, suberect. Length of antennae 0.55–0.60 mm; antennomeres I–II subcylindrical, 1.6 times as long as broad, III–V subcylindrical, 1.4 times as long as broad, antennomere VI subquadrate, VII elongate, 1.4 times as long as broad, VIII subtrapezoidal, IX transverse, 1.2 times as broad as long, X transverse,1.3 times as broad as long, XI subconical, 1.7 times as long as broad.
Pronotum subrectangular, moderately convex, widest near middle, length 0.39–0.40 mm, width 0.48–0.49 mm, with broadly rounded anterior margin, posterior margin weakly arcuate, sides strongly rounded in anterior third and almost parallel in posterior half; posterior corners obtuse. Lateral carina well-marked, finely microserrate. Puncturation fine, moderately dense, composed of small and shallow punctures; setation moderately long, suberect to erect.
Elytra oval, elongate, moderately convex, length 0.77–0.80 mm, width 0.52–0.54 mm, EI 1.44–1.48; widest in basal third; apices of elytra separately rounded. Each elytron with single basal fovea located in middle between humerus and scutellum; humeral carina as long as 1/7 of elytral length. Puncturation relatively fine, punctures shallow, moderately large, distance between punctures 0.6–2.2 times of their diameter. Setation moderately long, suberect to erect.
Metaventrite with oval median impression, weakly punctured, distance between punctures 2.0–3.0 times of their diameter, with short and sparse setation; metaventral process as broad as 1/3 of maximum metaventral width, posteromesal margin straight; lateral projections as long as broad, apex of each forming right angle with pointed tip.
Aedeagus (Figs. 46–47) length 0.37–0.38 mm, in ventral view with abruptly narrowing, elongate subtrapezoidal and blunt apical part, parameres slender with long apical seta; endophallus as in Fig. 48.
Legs moderately long and slender; protibiae as in Fig. 49.
Female. Very similar to male, except metaventrite slightly convex in middle; body length 1.30–1.32 mm; head length 0.14–0.15 mm, width 0.26–0.27 mm; length of antennae 0.54–0.56 mm; pronotum length 0.38–0.41 mm, width 0.48–0.50 mm; length of elytra 0.77–0.78 mm, width of elytra 0.53–0.55 mm; EI 1.42–1.45.
Distribution. Bulgaria.
Etymology. Locotypic, named after the Vitosha (Витоша) mountanis in western Bulgaria.
Remarks. The new species is similar to C. leonhardi, but it can be distinguished by the following combination of characters: 1) the body color, in C. leonhardi the elytra are darker, 2) a different structure of the aedeagus.
