Fusiform shell; spire whorls angular; subhorizontal subsutural shelf giving the spire a stepped appearance; oval aperture; short and wide siphonal canal; rather narrow U-shaped anal sinus; 12 to 16 rounded collabral ribs per whorl; superimposed thin spiral cords rapidly increasing in number by intercalation during growth; nodules at the intersections of ribs and cords. Protoconch: conical; 3 whorls; diameter about 530 µm (protoconch I: 310 µm); height about 560 µm; first 1.5 whorls (protoconch I) with spirally connected T-shaped granules forming a square reticulated pattern; subsequent whorls (protoconch II) with an oblique reticulated pattern of sinuous, collabral axial riblets and non-collabral prosocline riblets; the latter riblets absent in the adapical fourth, where only collabral riblets are present; transition to the teleoconch marked at a sinusigera. Occurrence . Box-corer samples BC71 (11 specimens), BC72 (1). Maximum height: 10 mm. Distribution and habitat . Pleurotomella demosia is distributed from the northeastern Atlantic southward to the Lusitanic province and the Mediterranean, in the 120–1980 m depth interval (Bouchet & Warén 1980; Poppe & Goto 1991; Bouchet & Taviani 1992). In Sardinian waters, it was found associated with a deep water population of Corallium rubrum (Crocetta & Spanu 2008). Fossil record.
