Alvania cimicoides (Hoenselaar & Goud, 1998) — De Frias Martins et al. 2009 (p. 62, figs. 152–153). Diagnostic characters. Conical shell; ovate aperture; thick labial varix; barely visible umbilical chink; commarginal ribs and superimposed spiral cordlets forming a rectangular reticulated pattern; small nodules at the intersections of ribs and spirals. Protoconch: conical; 2.75 whorls; diameter about 310 μm (protoconch I: 70 μm); height about 320 μm; first whorl (protoconch I) granular; subsequent whorls (protoconch II) with spiral zigzag elements, forming continuous lines near the sutures; transition to the teleoconch marked by a thin sinuous lip. Occurrence. Box-corer samples BC04 (6 specimens), BC05 (14), BC11 (4), BC22 (1), BC41 (1), BC66 (28), BC67 (14), BC68 (2), BC71 (4), BC72 (165); cores BC04 (5), BC05 (27), BC21 (41), BC51 (111), BC52 (1), BC67 (30), BC72 (41). Maximum height: 4 mm. Distribution and habitat. Alvania cimicoides is distributed from Greenland, Iceland and Norway to the Azores, the Canaries and the Mediterranean, dwelling on silty, sandy and rocky current swept bottoms in the 30– 2000 m depth interval, being more common between 100 and 1000 m (Fretter & Graham 1978; Bouchet & Warén 1993; Warén 1996; Pons-Moyà & Pons 1999). It has been regarded to represent a preferential characteristic element of the VP (bathyal mud) and CB (deep-sea white corals) biocoenoses (Di Geronimo 1979[a]; Di Geronimo & Bellagamba 1985). In the Santa Maria di Leuca CWC biotope, it was found on living colonies of Madrepora oculata (Mastrototaro et al. 2010), being very abundant in coral rubble, abundant in solitary coral and mollusk mud, and common in the Gryphus-Isidella thanatofacies (Rosso et al. 2010). Fossil record. Pliocene and Pleistocene of Italy; Holocene of Denmark (Monterosato 1 872; Seguenza 1903; Di Geronimo & Bellagamba 1985; Bouchet & Warén 1993; Di Geronimo & La Perna 1997; Petersen 2004; Di Geronimo et al. 2005).
