Type locality. Shirahone (Nagano Prefecture, Japan).

Diagnosis. Body length 2.9–3.2 mm. Dorsal vestiture with brown and white scales intermixed. Rostrum stout in both sexes, short in male, slightly longer in female, somewhat curved in lateral view, gradually and weakly tapered from base to apex. Pronotum moderately transverse, with recumbent scales. Elytra subglobose, short, slightly longer than wide, moderately wider than pronotum; interstriae covered with 3–4 irregular rows of recumbent to slightly raised scales. Mesofemora with small sharp tooth and metafemora with slightly more distinct sharp tooth; uncus of metatibiae in male distinctly pointed at apex.

Redescription. Length 2.9–3.2 mm. Body globose, stout. Integument black ( Fig. 7–10 View FIGURES 1–12 ). Rostrum stout in both sexes, short in male ( Fig. 28 View FIGURES25–36 ), slightly longer in female ( Fig. 29 View FIGURES25–36 ) (Rl/Rw male 4.11–4.44, female 4.40–4.80; Rl/Pl male 0.89–1.02, female 0.88–0.95), somewhat curved in lateral view, gradually and weakly tapered from base to apex. Antennae inserted between middle and apical third of rostrum in male, at middle of rostrum in female. Eyes flat. Pronotum moderately transverse (Pw/Pl 1.32–1.40), widest at base, then gradually narrowed to apex, with rounded sides, moderately convex, with recumbent brown and whitish intermixed, long, seta-like scales. Scutellum with short, light brown scales. Elytra subglobose, short (El/Ew 1.16–1.24), moderately wider than pronotum (Ew/ Pw 1.30–1.40), at base gradually directed forwards from interstria 5 to humeri, with somewhat rounded sides; interstriae covered with 3–4 irregular rows of recumbent to slightly raised, whitish and light brown intermixed, seta-like scales. Mesofemora with small sharp tooth and metafemora with slightly more distinct sharp tooth ( Fig. 47–50 View FIGURES 43–50 ), uncus of metatibiae 0.07–0.10 mm, in male distinctly pointed at apex ( Fig. 38 View FIGURES 37–42 ). Genitalia. Male: penis 1.84–1.90 mm in length, gradually narrowed from base to apex, with sides weakly concave at middle; endophallus at base with flagellum enlarged and connected with long and crooked sclerite ( Fig. 68 View FIGURES 67–72 ). Female: spermatheca 0.22– 0.27 mm, hook-shaped, with body thin, long, with sides parallel in basal half, then gradually narrowed to apex, with collum long, as long as half of body, with ramus very short ( Fig. 74 View FIGURES73–82 ). Spiculum ventrale 1.00 mm, with subparallel arms ( Fig. 79 View FIGURES73–82 ).

Remarks and comparative notes. This species is one of the few that is easily distinguishable from all the other Palaearctic species, mainly due to the uncommonly stout rostrum in both sexes and the pattern of the dorsal vestiture composed of whitish and light brown scales intermixed, which it shares only with C. danfengensis .

Distribution. Japan (Honshū Island), Russia (southern Russian Far East). New record from China (northeastern provinces).
