Status Cushman comments from 1931: "Under this name [Discorbina rosacea] there are a great many records from the Atlantic and other regions. It has been a favorite "dumping ground" for numerous discorbis-like forms. Of the many records for ''Discorbina rosacea," there are very few which figure the species and practically none of these can be referred to the same species. d'Orbigny's "Rotalia rosacea" is from the Miocene of the Bordeaux region well represented by Model No. 39. It is very clearly an Amphistegina of the less complex type. I have abundant specimens of this species from several localities in the Bordeaux region through the kindness of Prof. G. Dollfuss, and they are uniformly a rather high-spired Amphistegina. The structure is rather too complex to place them in Asterigerina as was done later by d'Orbigny, although they show well the transition from one of these genera to the other.
It becomes impossible to use this species name for any of the many forms of Discorbis called by various authors ''rosacea" and the problem of straightening out the various species involved can onlybe accomplished by a careful study of original material on which these records were based.
Brady's figures have undoubtedly been followed by many later authors. He has two species, one of which (pi. 8, fig. 1) is Discorbis advena Cushman. The other is an Indo-Pacific species common especially in the Australian region and unlike the western Atlantic forms which have been assigned to "Discorbina rosacea."" [details]

Identification The species R. rosacea described by d'Orbigny from the Burdigalian of Bordeaux differs from the many recent records from the Atlantic. As suggested by Cushman (1931), those records should be reworked.
For identification clarity the umbilical part is convex as explained by Poignant (1998). [details]
