MATERIAL AND DIMENSIONS. — Maximum height 9.4 mm, width 3.6 mm. — RGM.1364930 (17), leg. WG; RGM.1365013 (43), leg. ACJ; RGM.1365215 (1), leg. ACJ; RGM.1365118 (50), leg. AWJ; RGM.1365215 (1), leg. ACJ.
SPECIES CHARACTERISATION. — Small, fusiform shell. Protoconch not preserved. Five convex teleoconch whorls separated by weakly marked suture. Sculpture consists of 12 orthocline to prosocline, broad, round ribs and two spiral cords running over the ribs on the first teleoconch whorl, the third appears below the suture and the fourth above the suture on second whorl. Third whorl has 5 spiral cords. Last whorl with six spiral cords, continuing until the columella. Aperture ovate, extended by a broad, twisted siphonal canal.
DISTRIBUTION. — Upper Miocene: Atlantic, southwestern Spain (Cárdenas et al. 2019); central Proto-Mediterranean, Italy (Montanaro 1937: Venzo & Pelosio 1963). — Lower Pliocene: NSB, Coralline Crag, England (S.V. Wood 1848; Harmer 1915); Atlantic, Guadalquivir Basin, S. Spain (González-Delgado 1993); central Mediterranean, Italy (Chirli 1997; Brunetti & Cresti 2018). — Upper Pliocene: NSB, Red Crag, England (S.V. Wood 1848; Harmer 1915); western Mediterranean, Estepona Basin, southern Spain (Vera-Peláez 2002; Landau et al. 2022); central Mediterranean (Bellardi 1877; Cavallo & Repetto 1992). — Lower Pleistocene: central Mediterranean, Italy (Cerulli-Irelli 1914). — Middle Pleistocene: eastern Mediterranean, Rhodes Island (Chirli & Linse 2011). — Pleistocene (indeterminate): Atlantic, England (Harmer 1915, 1918). — Upper Pleistocene: western Mediterranean, Balearic Islands (Cuerda Barceló 1987). Holocene: NSB (Strand Petersen 2004). — Present-day: Atlantic: Norway (HØisaeter 2016), Scotland (E.H. Smith 1967), British Isles (Fretter & Graham 1984; Graham 1988), Galicia (Oliver et al. 2022), south to Portugal (Nobre 1931) and Canary Islands (Nordsieck & García-Talavera 1979); western Mediterranean (Bucquoy et al. 1882), central Mediterranean (Bogi et al. 1980; Cachia et al. 2001). Today it is occurs in the Atlantic from Norway (HØisaeter 2016), Scotland (Smith 1967) and British Isles (Fretter & Graham 1984; Graham 1988) to Galicia (Oliver et al. 2022), south to Portugal (Nobre 1931) and Canary Islands (Nordsieck & García-Talavera 1979) and in the western Mediterranean (Bucquoy et al. 1882) and central Mediterranean (Bogi et al. 1980; Cachia et al. 2001).
