Genetic confirmation of the first Mediterranean record of Holacanthus africanus Cadenat, 1951

Abstract

The first Mediterranean record of the pomacanthid Holacanthus africanus, caught within the Maltese waters, was assigned based on morphological and meristic characters. However, molecular and genetic analyses are required to confirm the taxonomic determination and avoid misidentification given the abundance of closely-related Pomacanthidae species and the biogeographic significance of this record for the Mediterranean. At the species level, the analyzed specimens gave a 99.7% identity match with H. africanus. This study represents yet another example of molecular analyses supplementing the conclusions of conventional morphological identification exercises.
