C. microprion is a shallow-water species usually found on silty reefs.


Maximum total length about 24 cm.


Following Boulenger’s (1895) influential work C. microprion was usually considered a synonym of C. pachycentron (C. boenak). Randall (1987) recognized C. microprion as a valid species, and distinguished it from C. boenak.
