Maturity: Lm ?  range ? - ? cm

A species belonging to the C. fimbriatus species group which is distinguished mainly from its congeners by having two large pale patches on its dorsal surface, one associated with the embedded third dorsal spine and another before the origin of the soft dorsal fin; mainly four neuromasts in the lower preopercular series (vs. mainly 3 in other congeners) (Ref. 94130).
Benthic (Ref. 58302). Edible (Ref. 637).
