Spiral sculpture on the last whorl of 18 cordlets, of which 8 above the aperture, with interspaces wider (x 1.5) than the cordlets. Cancellation rectangular, with small and elongated tubercles at the intersection of axials and spirals. Tubercles on the adapical cordlets of the first whorls narrow and spinulose. Sculpture visible in transparency throughout the internal shell wall. Anal sinus evident, corresponding to two spiral cordlets. Columella simple, slightly sinuous anteriorly, gently angled posteriorly. Outer lip with 11 strong inner denticles; the anteriormost, weakest, delimiting the siphonal canal and the posteriormost delimiting the anal sinus. Siphonal canal short, widely open, slightly curved.

On the last whorl, the eighth abapical cordlet becoming lighter toward the peristome, with some white spots. The two axials closest to the peristome white on the central part. » – Pusateri & al.: “A revision of the Mediterranean Raphitomidae 2: On the sibling species Raphitoma lineolata (B.D.D., 1883) and Raphitoma smriglioi n. sp.”, Iberus vol. 31(1), Barcelona 2013, p.13-14. – 12m deep, Vouliagmeni area, Attikí, SE. Greece. 6,03mm.
