Fissurella graeca var. caprensis Bellini, 1929a: 58

Type locality: Capri Island (Napoli, Tyrrhenian Sea, Italy) .

Original description: “con apice più elevato e reticolatura meno marcata” [with a more prominent apex and a less marked reticulate sculpture—with respect to Diodora graeca ( Linnaeus, 1758) , reported as Fissurella graeca L.].

Remarks: having been instituted as a geographic race, we rank it subspecific, and thus available ( ICZN 2012: Art. 10, glossary). Considered a junior synonym of Diodora graeca ( Linnaeus, 1758) by Fasulo (2012), although no figures were ever published by Bellini (1929a). The original description may easily fit several Mediterranean fissurellid limpets, all occurring in Capri Island and not even congeneric—e.g. Fissurella nubecula ( Linnaeus, 1758) , D. graeca , Diodora italica (Defrance, 1820) . Thus, it is considered a nomen dubium ( ICZN 2012: glossary).
