Helix surrentina var. anacaprica Bellini, 1915: 173 [ex Monterosato ms.]

( Fig. 8A )

Type locality: Capri Island (Naples, Italy) .

Original description: “striatura più sottile, colore più chiaro, fascie meno numerose, più tratteggiate, di colore giallo-bruno chiaro” [less prominent striae, lighter colour, less numerous colour bands, more dashed—with respect to Marmorana fuscolabiata (Rossmässler, 1842) , reported as Helix surrentina A. Schmidt —, yellowish-whitish in colour].

Material examined: two shells (both previously glued) labelled by Monterosato “preso 3 esempl— H. Anacaprica —Capri!! Monts—Non ut Surrentina ” [3 specimens sampled— H. Anacaprica —Capri!! Monts—Not like Surrentina] (MCCIC—drawer 22, n. 356) ( Fig. 8B, C ); eight shells labelled by Monterosato “ H. Anacaprica Monts—Di Anacapri—Is. di Capri” [ H. Anacaprica Monts—From Anacapri—Capri Island] and “Come H. Surrentina v. Anacaprica ( H. anacaprica Monts. ) in Bellini—Boll. Sc. Nat. Napoli Vol. XXVII 1914 pag. 173 t. 3 f. 6—Anacapri” (MCZR-M-4508) ( Fig. 8 D–F). Two glued shells labelled “Dono Monterosato” [Donated by Monterosato] and “ Helix (Murella) Surrentina A. Schm. —var.—(Iberus)—Cava dei Tirreni”, labelled by Monterosato “ Helix Surrentina A. Schmidt—var. [variety]—Cava dei Tirreni—leg. Monts—Oct. 1902” (MZF2—box 29, n. 168), are here reported for comparison ( Fig. 8G, H ).

Remarks: Helix surrentina Von Martens, 1858 is a junior synonym of Marmorana fuscolabiata (Rossmässler, 1842) ( Alzona 1971; Bodon et al. 1995). Having been instituted as a geographic race, we rank Helix surrentina var. anacaprica Bellini, 1915 subspecific, and thus available ( ICZN 2012: Art. 10, glossary). Considered a synonym of Marmorana fuscolabiata (Rossmässler, 1842) by some authors ( Sacchi 1955b; Fasulo 2013), whilst Alzona (1971) initially considered it a synonym of M. fuscolabiata and then a species dubia. Fiorentino et al. (2010) recently reviewed the Marmorana species complex, supporting a reassessment of their taxonomy both at genus and species level and calling for further analysis. Thus, H. surrentina var. anacaprica is here considered as belonging to the M. fuscolabiata species complex. Specimens ascribed to M. fuscolabiata were found again in Capri Island during recent field studies ( Petraccioli et al. 2005, 2006).
