Catophragminae is a subfamily of acorn barnacles. This subfamily includes the genera Catophragmus Sowerby, 1826, and Catolasmus Ross & Newman, 2001. Species included all have a calcareous basis, carinate imbricating plates, and with long multi-segmented caudal appendage.
Originally, Utinomi established Catophragminae as a subfamily of the Chthamalidae to include those genera with imbricating plate whorls. Chionelasmus was at first considered a chthamalid,40 but was later placed into its own family, Chionelasmatidae. Ross and Newman, 2001 re-established Catophragminae.
Catophragminae are the Northern Hemisphere representatives of the Catophragmidae. Their present range is Pacific Coast of Central America, Caribbean, Bermuda, Cuba, and tropical Western Atlantic. They prefer cryptic subtidal or lower intertidal locations on rocky shores.
