Published records. CHINA: BEIJING, JIANGXI, TAIWAN, ZHEJIANG (without specified localities; FIKÁČEK et al. 2015a).

Redescription. Length 1.6–2.3 mm. Yellowish red to reddish brown with black head and sternites; head, pronotum, and metaventral elevation with distinct longitudinal microsculptural lines ( Fig. 16 View Figs 9–16 ). Punctures on pronotum and elytral intervals fine and sparse. Elytral striae seven and eight more or less fused but series of punctures distinctly separated ( Fig. 12 View Figs 9–16 ), intervals flat basally but somewhat convex apically and laterally ( Figs 9, 11 View Figs 9–16 ). Paramere ( Figs 13, 14 View Figs 9–16 ) ca. 1.25× as long as phallobase, gradually narrowed from base to middle, almost parallel from middle to subapex, distinctly expanded outwards, with membrane and setae subapically inwards. Median lobe broad, almost parallel at basal four-fifth, abruptly narrowed at apical fifth and gradually narrowed apicad, gonopore situated subapically.

Differential diagnosis. This species is similar to C. minutum , but it can be easily distinguished from the latter by its light color, and the pronotum, elytra and metaventrite with finer and moderately dense punctures. The head, and disc of the pronotum and metaventrite have distinct short longitudinal microsculpture between punctures.

Biology. Living in decaying organic material, particularly in compost heaps, barn manure, excrements of mammals (e.g. horse and cattle dung), among various plant debris, also in nests of birds ( RYNDEVICH & LUNDYSHEV 2005). This species can be easily collected at light from April to November in South China.

Distribution. Widespread in Eastern Palearctic and China, in early 20th century introduced to North America, and in 1960ʼs to Europe ( SMETANA 1978, HANSEN 1999). In China previously recorded from Beijing, Jiangxi, Taiwan and Zhejiang. Newly recorded for Fujian, Guangdong, Guangxi, Guizhou, Hebei, Hubei, Hunan, Nei Mongol, Qinghai, Shaanxi, Shanghai, Shanxi, Sichuan, Yunnan.
