Etymology: Parapriacanthus: Greek, para = near + Greek, prion = saw + Greek, akantha = thorn (Ref. 45335); punctulatus: Name from Latin 'punctulatus' for dotted; referring to the profusion of dark dots on the side of the body below the lateral line that extend well posterior to the origin of the anal fin; these dots are more evident on preserved specimens than in life.
