Abstract:

Partial sequences of the 1st intron of S7 ribosomal protein gene among four genera and 10 species of Haemulidae fish were analyzed. A phylogenetic tree was constructed using the MP and NJ methods. The results show that 10 Haemulidae fishes were divided into two clades in the phylogenetic tree: with one clade composed of Hapalogenys and Plectorhynchus, and another, of Pomadasys and Haemulon, so the 10 Haemulidae fishes forming a monophyletic group. The genera Hapa-logenys and Plectorhynchus had a close relationship. Based on genetic distance, Hapalogenys and Haemulon were more closely related than Hapalogenys and Pomadasys. So our study supports the viewpoint that the phylogenetic position of Ha-palogenys was between Plectorhynchus and Haemulon and could not be upgraded to the family of Hapalogeniidae.
