A new endemic Actinia species (Actiniaria: Actiniidae) from the central Macaronesian Archipelagos

The presence of some endemic taxa of the genus Actinia from Madeira and the Canary Islands is discussed. A new species, Actinia nigropunctata, is described, and some characters of the poorly known Actinia virgata are discussed. In addition, we discuss the main characters proposed by Schmidt (1971) to distinguish species of Actinia.
