Length 26-31 mm. The elytral sculpture of C. lugens is confused and all intervals are flattened but still it is possible to recognize grainy alignments with a pattern of pentaploid type. On the primary intervals there are small cupric foveae that, carefully watching, stand out on the dark color of the upper body.
C. lugens is found throughout northern China and Mongolia up to Kraj Primorskij in Russia. According to data from Kwon & Lee (1984), the species is also present in various locaties in North and South Korea of which Imura (2010) shows the map. Moreover, Imura, reviewing all existing data for the Far East, also mentions, albeit with some doubts, three isolated catches in Japan (Tsunugawa and Yakeyama in Honshu and the Mt-dake of Shiretoko in Hokkaido).
