The mean nucleotide diversity was found to be 0.0792. Average sequence divergence between species of Sebastidae and Scorpaenidae was 8.4%, and 6.4%. between species of the genus Scorpaena. For congeneric comparisions, the lowest genetic divergence (0.7%) was observed between S. porcus and S. notata, and the highest divergence (10.8%) was detected between S. maderensis and S. notata. High levels of nucleotide divergence were detected between species of two families, and the maximum value was found to be 14.5% between H. dactylopterus and S. elongata. The two phylogenetic methods (NJ and MP) identified twomajor lineages. In theNJ tree S. elongatawas the sister group to S. scrofa. S. maderensis was more divergent from these groups. Another lineage contained S. porcus and S. notata. The topology of the MP tree is similar to that of the NJ tree. The pattern and degree of morphological differentiation was not congruent with the genetic differentiation. The Euclidiean distances of morphological data revealed very high morphological divergence between the two families. The highest morphological divergence was observed betweenH. dactylopterus and S. porcus, and the lowestwas detected between S. elongata and S. notata.
