Like so many other serpulid genera, Ditrupa has a history of taxonomic confusion, even to the extent that the worm tubes have been included in the Mollusca by some workers. In recent publications, most authors follow Fauvel (e.g. 1953) and recognise a single species, Ditrupa arietina O.F. Miiller, 1776, worldwide, despite the fact that descriptions of this species were based on European and Atlantic material. A re-examination of type specimens and study of a broad range of samples from the Indo-Pacific now justifies the recognition of a separate species, Ditrupa gracillima Grube, 1878, from this region. It shows extreme variation, at least partly related to depth: from 100 m downwards an ecophenotype prevails, previously described as D. arietina var. monilifera.

Distribution
distribution: Atlantic Ocean and Mediterranean Sea (see ten Hove & Smith 1990) [details]
Editor's comment
Mostly Scaphopoda, but the part which is referred to as "Hake's tooth" is likely to be Ditrupa arietina [details]
Status
not serpulid but belongs to the Foraminifera, assigned to Lagena laevis by e.g. Brown (1827) [details]
Syntype
in Wroclaw #272 (see Wiktor 1980) and Zoological Museum Berlin #1560 [details]
Taxonomy
erected for Dentalium corneum non Linnaeus sensu Lamarck (mostly = Ditrupa arietina); for Dentalium coarctatum ... [details]
Taxonomy
in Mörch (1863: 426-427) mentioned as synonym of Ditrupa gadus Montagu, variant spelling of Ditrupa, and probably ... [details]
