Jujubinus eleonorae new species

(Figs 1.1–1.6; 2.1–2.4; 3.1–3.5)

Diagnosis: Small and stout shell; flat spiral cords, ratchet spiral sculpture; distinct basal cord; prosocline lamellae absent between cords.

Description: Shell of small size for the genus, conical, solid, holotype 5.7 mm high, 4.7 mm in diameter. Usually 5–5.5 mm, rarely up to 6 mm high, 4–4.5 mm in diameter. Protoconch smooth, 240–250 µm in diameter, comprising about 1.3 whorls. Teleoconch of 4.5–5.5 whorls; whorls slightly convex, with 6–7 flat spiral cords including the basal one; spiral cords of about the same strength, slightly shouldered. Basal cord pronounced, rounded and divided by a furrow, which produces two parallel cordlets, the lower twice as wide as the upper one. Suture barely visible. Whole teleoconch surface covered by faint prosocline growth striae, in some specimens more evident and irregular. Base convex, with 4–5 flat concentric spiral cords, regularly spaced, crossed by numerous growth striae. Umbilicus closed also in juveniles, covered with a white callus. Aperture quadrangular, with a columellar callus thickened in the middle portion. Interior of the aperture whitish nacreous. Colour of protoconch and initial teleoconch whorls bright red, remaining whorls and base green-brownish with three regularly spaced yellowish-orange bands covering a portion of the spiral cords. Yellowish-orange bands increasing in number (4–5) on the teleoconch base.

Type material: One hundred and twenty two shells from the type locality. Holotype: MNHN 25883; paratype 1: MZB 49668; paratype 2: MCZR 00227; paratypes 3–39: CS-PM; paratypes 40–59: EDS; paratypes 60–69: MO; paratypes 70–79: IN; paratypes 80–119: PT; paratypes 120–121: BA.

Other material examined: Twenty-five specimens from type locality: MO; 606 specimens from type locality: IN.

Etymology: The species name is after Eleonora De Sabata, marine photo-journalist who provided the marine sediment which yielded the studied specimens.

Locus typicus: Skerki Bank (37°45’00”N, 10°50’00”E), infralittoral bottom, at a depth of 37 m, Sicily Channel, Mediterranean Sea.

Distribution: Only known from the type locality.
