Dizoniopsis coppolae (Aradas, 1870)
Mediterranean. Predator on sessile preys in the infralittoral, among photophilic algae on coarse sand or fine gravels, or around Posidonia patches on hard substrate. Original taxon: Cerithium coppolae. Synonym: neglectum Sowerby II, 1856.
 
« Shell high, conical, solid. […] Protoconch narrow and styliform, easily broken off, with convex whorls and a sculpture of flexuous axial riblets which start from the adapical suture and gradually fade out; these are irregularly distributed on the last protoconch whorls and vary in strength among individuals. Sculpture of teleoconch composed by two spiral cords, approximately as broad as the intervening space, crossed by axial ribs which form very distinct beads at their intersection with the cords. On the first teleoconch whorl, the abapical cord is more prominent than the other one and the axial ribs are not very conspicuous. On the following whorls, the adapical cord progressively takes over as the thickest one. » – Bouchet & al.: “Notes on mediterrranean Dizoniopsis…” Iberus 28(2), 2010, p.53.

40m deep, Cannizzaro, Catania, E. Sicily. 5mm.
Dizoniopsis: two rows of buttons per whorl of teleoconch.
 
« On the last whorl, the beads of the adapical cord become slightly more elongated but do not split. The abapical part of the body whorl bears one cord, slightly ragged but not beaded, in prolongation of the suture, and two more similar cords between this and the siphonal canal; these cords are markedly narrower than the beaded cords on the ribs and the spaces between them are crossed by raised threads parallel to the growth lines. Aperture oval, with a broad and short siphonal canal and a smaller channel at the opposite end. […] Colour brown, grading to paler or even white towards the apical whorls; the nodes are paler with a greyish hue contrasting with the dark brown on spaces between nodes on the cords, and the abapical cords are also somewhat darker than the intervening spaces. » – Bouchet & al.: op. cit. The species is dedicated to the sicilian musician P. A. Coppola (1793-1877), composer and conductor.
