« Shell spindle-shaped […]decorated with axial costae – of which 8 on last whorl – of rounded section, with slight bend at suture insertion. Very thin spiral striae – in a few specimens alternating with a few in higher relief – in intervals between axial costae. Aperture elongate, narrow, hardly higher than half last whorl. Anterior canal relatively short, straight, sculptured with striae that are sparser, more oblique and more prominent than those between axial costae. C-shaped posterior sinus thickened by callous extending over inside outer lip. Thick, wide varix outside rim of lip. Protoconch paucispiral (< 1.5 whorls), smooth apart from a few markedly arched axial folds, crossed by a series of very slender spiral striae, microsculpture marking passage to teleoconch. » – Spada & Della Bella: “Identification and neotype designation of Mangelia striolata, type species of Mangelia Risso, 1826 (Neogastropoda, Conoidea)”, Bollettino Malacologico vol.46, Milano 2010, p.80.

« Background colour ranging from whitish to ivory, with spiral yellowish stripes that become denser on lower half of last whorl. Small brown spirally elongate maculation visible on outer lip halfway down last whorl. » – Ibid.
