Type material. MCZR–M–14178 —1 sh “ A. corbuloides Monts Grande esemplare di Civitavecchia (Donati)”// 1 sh “A. corboloides Monts d’Algeria! coll. Tiberi……”

Type locality. Described from Palermo (Sicily), Civitavecchia (Italy) , Algeria, and southern Spain .

Remarks. Monterosato proposed the name for his Arca polii var. “ grandis ” Monterosato (1875a: 12), regarded as distinct from Arca polii Mayer, 1868 . The varietal name “ grandis ” is a nomen nudum, and the binomen Arca corbuloides must be adopted. The syntypes found in the Monterosato collection originated from the Donati and Tiberi collections. They match very well part of the material reported in the original description. Recorded by MolluscaBase (2018) as Anadara corbuloides (Monterosato, 1878) .
