Abstract
-
The monophyly of the Centrarchidae is supported by the presence of prominent wing-like transverse processes on the first haemal spine and more than one anal pterygiophore united with the first haemal spine groove. Two subfamilies are recognized within the Centrarchidae. The Elassomatinae with one monophyletic genus Elassoma is characterized by numerous reductive characters. The Centrarchinae consists of eight monophyletic genera, Micropterus, Lepomis, Enneacanthus, Acantharchus, Ambloplites, Archoplites, Centrarchus, and Pomoxis based mainly on a combination of synapomorphies associated with the haemal-anal-axial character complex. A cladogram of the most parsimonious hypothesis of relationships for the genera of the Centrarchidae established by the present study is congruent with the previous phylogenetic relationships proposed by Smith and Bailey (1961) and Mok (1981). In an attempt to evaluate the potential utilization and understanding of the haemal-anal-axial character complex, representative taxa from major groups of teleosts are surveyed. The sister group relationship between the Centrarchidae and Percichthyidae is suggested and the systematic usefulness of the haemal-anal-axial character complex at different taxonomic levels is indicated.
