A new species of armored searobin, Peristedion, from the western Atlantic Ocean is described. It is distinguished from P. antillarum in having more numerous lip and chin barbels, shorter and broader rostral exsertions, and a spinous, serrated perifacial rim, and from all other western Atlantic species in having two or three serrated ridges on the mandible. Methods and terminology are revised and clarified. Taxonomic problems resolved are: Acanthostedion = Satyrichthys, Peristedion spiniger = P. truncatum, P. bartschi = P. longispatha, P. taeniopterum = P. gracile, P. megintyi = P. miniatum, and P. schmitti = P. thompsoni. “Acanthostedion” is proposed to describe the postlarval stages of peristediids. P. ecuadorensis does not occur in the Pacific; its type locality is corrected to the western Atlantic.
