Diagnostic characters. Fusiform shell; oval aperture; moderately long and twisted siphonal canal; rather deep anal sinus; 11 collabral ribs per whorl crossed by spiral cordlets; short recurved spines at the intersections of ribs and cordlets; stronger spines bordering the subsutural shelf. Protoconch: conical; 3.5 whorls; diameter about 480 µm (protoconch I: 250 µm); height about 630 µm; first 1.5 whorls (protoconch I) with spirally connected T-shaped granules forming a square reticulated pattern; subsequent whorls (protoconch II) with sinuous, collabral, opisthocyrt axial riblets and non-collabral prosocline riblets; the latter riblets absent in the adapical third, where only collabral riblets are present; terminal spiral keel; transition to the teleoconch at sinusigera.
Remarks. A single juvenile specimen was at hand.
Occurrence. Core BC21 (1 specimen). Height: 2 mm.
Distribution and habitat. Pleurotomella eurybrocha ranges from the northeastern Atlantic to the Azores and the Mediterranean, being a soft bottom dweller at bathyal depths, occasionally found at lower settings in the Mediterranean ( Panetta 1971; Nordsieck 1977; Bouchet & Warén 1980; Poppe & Goto 1991). It was regarded as a characteristic element of the VP (bathyal mud) biocoenosis ( Di Geronimo et al. 1982).
Fossil record. Possibly Pleistocene of Sicily ( Di Geronimo et al. 1982 as P. cf. eurybrocha ).
