1) The objective of this study were fivefold: to establish the monophyly of the perciform family Sciaenidae; to determine the phyletic position of the family within the suborder Percoidei; to determine intergeneric relationships within the family; to provide a zoogeographic analysis compatible with sciaenid evolution; and to present a new higher classification reflecting sciaenid phylogeny. 2) Relationships were analyzed by cladistic methods based on morphological, osteological, and myological characters. Character polarities were determined according to one or more of the following: taxonomic outgroup comparison and functional outgroup comparison. Zoogeographic analyses followed the progression rule of Hennig (1966). 3) Monophyly of the Sciaenidae is demonstrated by 21 synapomorphies. 4) No close relationship of the Sciaenidae to other percoid families was detected. An earlier held view that the Sciaenidae is a sister group of the Haemulidae is rejected, since the Gerreidae is the sister group of the latter. The retention of a series of primitive features by the Sciaenidae indicates that the family has arisen early in percoid evolution
