It is known only from a stuffed specimen described by Albert Günther in 1870, which has since been lost. In 1970, Springer and Collette assigned a jaw, tail, and two embryos from off Sierra Leone to this species, but later investigation found that the jaw belonged to a guitarfish, and the tail and embryos to a different species, possibly Dasyatis hastata.[1] References1. ^1 {{Cite journal | author = Séret, B. | author2 = Couzens, G. | author3 = Valenti, S.V. | last-author-amp = yes | title = Hypanus rudis | journal = The IUCN Red List of Threatened Species | volume = 2016 | page = e.T161620A104133548 | publisher = IUCN | date = 2016 | url = http://www.iucnredlist.org/details/161620/0 | doi = 10.2305/IUCN.UK.2016-3.RLTS.T161620A104133548.en | access-date = 23 December 2017}} {{Taxonbar|from=Q3016849}}{{Rajiformes-stub}} 2 : Dasyatis|Fish described in 1870 |
