Partial sequences of 16S and 12S mitochondrial ribosomal DNA were used to examine the phylogenetic relationships of the primarily eastern Pacific genus Paralabrax (Perciformes: Serranidae) and allied taxa. Paralabrax is considered a basal serranine, which is itself considered the basal subfamily in the Serranidae. Multiple serranines reported closely related to Paralabrax from the genera Serranus, Hypoplectrus, Cratinus, and Centropristis were used as outgroups. Species from the remaining two subfamilies, Epinephilinae and Anthiinae, of the Serranidae were also used in the analyses. The tree of the Serranidae was rooted with the families Polyprionidae and Priacanthidae. Paralabrax, the Serranidae, and the Serraninae were monophyletic in this study. Serranus was found to be paraphyletic. Centropristis, formerly considered the sister taxon to Paralabrax, was not closely related in these analyses. Cratinus agassizii, a monotypic genus from the eastern Pacific, was found to be the sister taxon to Paralabrax. There is greater resolution for intergeneric and subfamily relations than interspecific relationships. A single most parsimonious tree for the interspecific relationships of Paralabrax and allied taxa is proposed. This proposed molecular phylogeny is consistent with known biogeographic processes in the eastern Pacific.
利用16S和12S线粒体核糖体DNA的部分序列来研究东太平洋沿岸主要的副平鲉属（鲈形目：鮨科）及相关类群的系统发育关系。副平鲉属被认为是鮨科基部类群，而鮨科本身又被认为是鮨科中的基部亚科。将多个与副平鲉属关系密切、分别来自锯鮨属、低纹鮨属、小岩鮨属和尖吻鲈属的鮨科鱼类作为外类群。鮨科其余两个亚科，石斑鱼亚科和花鲈亚科的物种也用于分析。鮨科的系统发育树以叶鲷科和天竺鲷科作为根节点。在本研究中，副平鲉属、鮨科和鮨亚科均为单系类群。发现锯鮨属是并系类群。以前被认为是副平鲉属姐妹分类单元的尖吻鲈属，在这些分析中与其关系并不密切。发现阿氏小岩鮨，一种来自东太平洋的单型属鱼类，是副平鲉属的姐妹分类单元。属间和亚科间关系的分辨率高于种间关系。提出了一个关于副平鲉属及相关类群种间关系的最简约树。这个提出的分子系统发育与东太平洋已知的生物地理过程一致。
