D. marianae is close to culteriana by its marked spiral sculpture, but differs from the latter by a smaller size, a more elevated spire, the more numerous spiral cords, and by the spirals of the protoconch (not visible on the picture). The species is named «  in honour of Marian Ramos, Director of the “Fauna Ibérica” project, for her contribution to Zoology in Spain. » – Rubio, Dantart & Luque: “Two new species of Dikoleps (Gastropoda, Skeneidae) from the Mediterranean coast of Spain”, Iberus vol.16(1), Barcelona 1998, p.88.
