Complete Cyt b gene sequences (1 141 bp) of 9 species of 8 genera from the Carangidae and Pomadasys maculates in the China Sea were cloned and sequenced. Together with homologous sequences of 14 species of 4 genera from the Carangidae in USA, Angola, Greece and Panama Sea downloaded from GenBank, molecular phylogenetic trees were reconstructed by maximum parsimony (MP) and neighbor-joining (NJ) methods using Pomadasys maculates as the designated outgroup. The phylogenetic analysis showed that: (1)  classifying the Carangidae into four subfamilies Caranginae, Seriolinae, Trachinotinae and Chorineminae was acceptable; (2) it is incorrect to define subgenus in Caranx of Caranginae; (3) Alepes djedaba and Alepes kleinii have a close relationship, so they belong to the same genus; (4) nominating Trachinotus blochii as Trachinotus ovatus in the current systematic synopsis of fishes in China is not approporiate and thus should be revised accordingly[Acta Zoologica Sinica 53(4):641–650, 2007].
