Alvania testae (Aradas y Maggiore, 1843)— Giribet & Peñas 1997 (p. 62, figs. 7, 9, 10). Diagnostic characters . Conical, slightly cyrtoconoid shell; ovate aperture; moderately thick labial varix; imperforated base; commarginal ribs and superimposed spiral cordlets forming a squarish reticulated pattern; small nodules at the intersections of ribs and spirals. Protoconch: conical; 2.5 whorls; diameter about 290 µm (protoconch I: 130 µm); height about 230 µm; first whorl (protoconch I) with spiral lines forming a polygonal pattern adapically; subsequent whorls (protoconch II) with sparse granules adapically, widely spaced oblique bars medially and irregular spiral threads abapically; transition to the teleoconch marked by a sinuous lip. Remarks . Alvania abyssicola (Forbes, 1850) is currently regarded as a junior synonym (CLEMAM 2016; WoRMS 2016). The closely related A. subsoluta (Aradas, 1847) differs in having a larger (about 400 µm) and differently scupltured protoconch of the lecitotrophic type (cf. Oliverio et al. 1993). Occurrence . Box-corer sample BC72 (5 specimens); cores BC05 (3), BC21 (2), BC72 (1). Maximum height: 2.5 mm. Distribution and habitat . The species ranges from northern Norway to Morocco (to 31° N) and the Mediterranean, as far East as Israel; it dwells on mud, sand, clay and coral rubble in the 15–1085 m bathymetric interval, occasionally deeper (Panetta 1971; Fretter & Graham 1978; Barash & Danin 1982; Warén 1996; Giribet & Peñas 1997; Petersen 2004). It is present in the VP biocoenosis (Di Geronimo et al. 1982; Della Bella & Tabanelli 2004). Fossil record.
