Typically only one of the body parts is modified (most often the elytra), but in some cases multiple modifications occur. This species group currently comprises 11 species, all occurring in China : C. bicolor Jałoszyński, 2007a , C. excavatus Jałoszyński, 2007a , C. hamatus Jałoszyński, 2007a , C. spinosus Jałoszyński, 2007a , C. superlatus Jałoszyński, 2007a , C. baculifer Jałoszyński, 2007b , C. caudatus Jałoszyński, 2007b , C. nigricollis Jałoszyński, 2007b , C. scolytoides Jałoszyński, 2007b , C. subcaudatus Jałoszyński, 2007b and C. uenoi Jałoszyński, 2007b .
