Putzeysia wiseri ( Calcara, 1842) — Giannuzzi-Savelli et al. 1994 (p. 84, fig. 263); Repetto et al. 2005 (p. 89, top right fig.); Portalatina 2008 (p. 155, fig. 4A); Mastrototaro et al. 2010 (fig. 5 c).

Diagnostic characters. Trochiform shell; umbilical chink closed by parietal callus in most specimens; rounded prosocline aperture; thin, prosocline collabral riblets and superimposed spiral cords; spiral cords increasing in number by intercalation during growth; nodules at the intersections of riblets and spiral cords; strongest spiral cord suprasutural forming the periphery. Protoconch: low, consisting of 1.25 whorls; diameter about 310 µm; surface finely granulated; transition to the teleoconch marked by a simple, slightly everted lip.

Occurrence. Box-corer samples BC04 (1 specimen), BC05 (2), BC11 (1), BC22 (1), BC66 (7), BC67 (7), BC68 (2), BC70 (2), BC71 (59), BC72 (21); cores BC05 (1), BC21 (1), BC72 (3). Maximum height: 5.5 mm.

Distribution and habitat. Putzeysia wiseri is distributed from the NE Atlantic to the Mediterranean, dwelling on coralline or muddy bottoms between 150 and 3000 m depth, but being more frequent in association with deep water corals in the 500–2000 m interval; it is possibly a cold-water species relict on deep water corals ( Ghisotti & Melone 1971; Guidastri et al. 1984; Poppe & Goto 1991; Ratmeyer et al. 2004). It has been regarded to represent an exclusive characteristic element of the VP (bathyal mud) biocoenosis (Di Geronimo 1979[a]) and an associated element of the CB (deep-sea white corals) biocoenosis ( Guidastri et al. 1984). In the Santa Maria di Leuca CWC biotope, it was found on living colonies of Madrepora oculata (Mastrototaro et al. 2010) , being common in coral rubble and solitary coral thanatofacies (Rosso et al. 2010).

Fossil record. Pliocene (doubtful) of Sicily ( Guidastri et al. 1984); Pleistocene of central and southern Italy (Di Geronimo 1979[a]; Di Geronimo & Li Gioi 1980; Guidastri et al. 1984; Di Geronimo & Bellagamba 1985; Di Geronimo & La Perna 1997; Di Geronimo et al. 2005). The species was originally described by Calcara (1842) on fossil material from Sicily; other authors (Ghisotti & Melone 1 971; Guidastri et al. 1984) recorded it from the same sediments as Trochus gemmulatus .
