Jujubinus seguenzae Ghisotti & Melone, 1975 |
Northeastern coast of Sicily, in the shallow infralittoral. Grazer in rocky algal environment. Protoconch: 1 whorl, flattened, of the same colour than that of the background of the teleoconch, densely covered with irregular microgranules, which rapidly merge together into a pair of spiral threads. Teleoconch: about 5 whorls, the first one dome-shaped, the others being almost flat and separated from each other by a shallow suture. Sculpture made up of 8 flat spiral beads, twice as large as their interspaces, and of almost the same strength, except the two spirals close to the suture, which are slightly more marked; spirals and interspaces are crossed by numerous prosocline micro-striae. The periphery is angled, the base almost flat; columella straight, slightly folded. Above and below: a specimen collected on Ulva lactula Linné, Messina. 4,4mm. Original pictures provided by A. Nappo (IT). – (CC BY-NC-SA) – |
On the pale greenish background, some more or less orthocline areas concentrate dark blotches, on the spiral beads exclusively; there are some color gradients between these blotches and the background, both on beads and interspaces. |
