2004 Distorsio cancellina (Lamarck) – LANDAU et al., p. 71, pl. 6, figs 1–3 (cum syn.).

2013 Distorsio cancellina (Lamarck) – LANDAU et al., p. 132, pl. 19, figs 10–12 (cum syn.).

Material – 103 specimens (SL 14–43); HNHM: INV 2017.690 . (Figs 57– 58), INV 2017.691. (4) , 98 specimens in private collections.

Description – Fusiform shell, moderately elevated, irregularly coiled spire, six teleoconch whorls, last whorl expanded to left of the aperture. Denticulate aperture, short, recurved siphonal canal, short fasciole. Spiral sculpture of narrow cords, axial sculpture of rounded ribs and low varices with small tubercles at the intersections.

Remarks – The revision of the taxon was accomplished by LANDAU et al. (2004). In Hungary the species was recorded from the Börzsöny and Cserhát Mts as Triton tortuosum Borson ( NOSZKY 1925), but it has never been illustrated in the Hungarian literature. D. cancellina is rare at the Paratethys localities; its abundance in the mollusc assemblage of Letkés is noteworthy.

Distribution – Burdigalian-Tortonian: PMS ( Italy), late Burdigalian-Langhi- an: NSB ( the Netherlands, Germany), Aquitanian-Serravallian: NEA ( France), Badenian:CP ( Austria, Bulgaria, Hungary, Romania), Langhian-Serravallian:PMS ( Turkey), Tortonian: NEA ( Portugal).
