Etymology: The specific epithet is the past participle of the Latin verb frangere (to fold, to break) and alludes to the subapically distinctly curved male protibiae.

Description: Body length 1.1–1.3 mm; length of pronotum 0.38–0.42 mm; width of pronotum 0.45–0.51 mm; length of antennae 0.55–0.60 mm. Habitus as in Figs 2–3 View Figs 1–8 . Colouration: body reddish to brown, often with the elytra somewhat darker than the head and pronotum.

Eyes composed of 6–8 ommatidia. Antenna of similar shape as in C. bodemeyeri .

Pronotum approximately 1.2 times as broad as long, broadest in anterior half, and moderately convex in crosssection; lateral margins straight in posterior half.

Elytra noticeably broader than pronotum, anteriorly with a subcircular impression with tomentose whitish pubescence; humeral carina fine, approximately as long as the combined length of the basal three antennomeres.

: protibia distinctly bent subapically and flattened in subapical portion, apically dilated; metaventrite extensively flattened, but not distinctly impressed; aedeagus ( Figs 32 View Figs 25–35 , 46 View Figs 36–47 ) long and slender, 0.60–0.66 mm long; ventral process constricted in the middle and apically with a moderately long apical extension in ventral view; internal sac with weakly sclerotized small structures; paramere long and straight, extending to apical fifth of ventral process, with a long and weakly curved apical seta.

Comparative notes: This species is distinguished from the similar C. bodemeyeri by slightly shorter antennae, slightly smaller eyes, smaller and more circular anterior tomentose impressions on the elytra, subapically more sharply bent male protibiae, and a longer and more slen- der aedeagus with a differently shaped ventral process with a shorter apical extension, by straight parameres, and by internal structures of different shapes.

Distribution and natural history: The distribution is confined to Bursa, Balıkesir, Kocaeli, and Çanakkale provinces, Northwest Anatolia ( Map 2 View Map 2 ). The specimens were sifted from litter in beech and hornbeam forests, mostly with rhododendron undergrowth and often in dark stream valleys. The altitudes range from 600 to 1430 m. In one locality in Kocaeli, the species was collected together with C. bodemeyeri .
