Diagnosis. Puncturation on frontoclypeal region and vertex fine, very sparse; antennomere VII elongate, 1.2 times longer than broad, VIII nearly spherical; pronotum subrectangular; in males metaventrite with shallow median oval transverse impression and metaventral process as broad as about 1/3 of maximum metaventral width, posteromesal margin slightly cancave; aedeagus in ventral view with elongate subtrapezoidal apical part demarcated by deep lateral constriction and parameres in ventral view with broadened apices and subtriangular projection, with very short apical seta.
Description. Male. Body length 1.33–1.38 mm, moderately convex, pronotum reddish-brown; elytra brown; legs, mandibles and antennae slighty brown; tarsi and mouth parts yellowish, setation yellowish.
Head broadest across moderately large eyes; length 0.15–0.17 mm, width 0.27–0.30 mm; frontoclypeal region subtrapezoidal, slightly convex; vertex slightly convex; supraantennal tubercles weakly raised. Puncturation on frontoclypeal region and vertex fine, very sparse, setation moderately long, suberect. Length of antennae 0.57–0.60 mm; antennomere I subcylindrical, 1.4 times as long as broad, II subcylindrical, 1.3 times as long as broad, antennomeres III–IV about as long as broad, V slightly longer than broad, VI about as long as broad, VII elongate, 1.2 times longer than broad, VIII nearly spherical, IX transverse, 1.2 times as broad as long, X transverse, 1.5 times as broad as long, XI subconical, 1.5 times as long as broad.
Pronotum subrectangular, moderately convex, widest near anterior third, length 0.40–0.43 mm, width 0.49–0.51 mm, with broadly rounded anterior margin, posterior margin weakly biemarginate. Lateral carina wellmarked, microserrate, sides strongly rounded in anterior third, posterior corners blunt. Puncturation very fine, moderately dense, composed of small and shallow punctures; setation moderately long, suberect to erect.
Elytra oval, elongate, moderately convex, length 0.76–0.80 mm, width 0.56–0.59 mm, EI 1.33-1.39; widest slightly anterior to middle; apical margins of elytra almost straight. Each elytron with single basal fovea located in middle between humerus and scutellum; humeral carina as long as 1/10 of elytral length. Puncturation coarse, punctures shallow, distance between punctures 1.1–2.2 times of their diameter. Setation moderately long, suberect to erect.
Metaventrite with shallow median oval transverse impression, sparsely punctured, distance between punctures 0.5–1.5 times of their diameter with moderately short setation; metaventral process as broader as about 1/3 of maximum metaventral width, posteromesal margin slightly cancave; lateral projections 1.2 times longer than broad, apex of each forming right angle with blunt tip.
Aedeagus (Figs. 18–19) length 0.50–0.53 mm, in ventral view with elongate subtrapezoidal apical part demarcated by deep lateral constriction; parameres (Fig. 21) in ventral view with broadened apices and subtriangular projection and each paramere with very short apical seta¸endophallus as in Fig. 20, simple.
Legs moderately long and slender; protibiae as in Fig. 22.
Female. Very similar to male, except metaventrite which is in middle slightly convex; body length 1.34 mm; head length 0.16 mm, width 0.28 mm; length of antennae 0.56 mm; pronotum length 0.42 mm, width 0.51 mm; length of elytra 0.76 mm, width of elytra 0.57 mm; EI 1.33.
Distribution. Serbia and Bulgaria.
Etymology. The name ” fallax “ (in Latin „false“) refers to the appearance of the new species that resembles C. fairchildi.
Remarks. See remarks for C. fairchild sp. n.
