The anatomy of the pelvic girdle of acanthomorph fishes is reviewed. Derived morphological features of the pelvic complex are identified and discussed as evidence for the recognition of a monophyletic Acanthomorpha, Acanthopterygii and Percomorpha. Within the Percomorpha, evidence is presented to support the grouping of the Holocentridae with the remaining percomorph assemblage. An additional sub-grouping of “higher percomorphs” is also proposed.
