The diagnosis follows Bischoff (1964). Cytherelloidea btaterensis Bischoff, 1964 resembles Cytherelloidea circumvallata Bonnema, 1941 (middle Albianearly Cenomanian of the Netherlands) (Bonnema 1941; Grndel 1966), but the latter has an extra central ridge, which is absent in the former. Cytherelloidea knaptonensis Kay, 1963, from the Albian of Lebanon (Bischoff 1964), can be separated from the present species by its ornamentation, which does not include reticulations and punctuations between the ridges; also, the shape of the posterior ridge is remarkably different, especially along the dorso-posterior margin. A similar species, Cytherelloidea kayei Weaver, 1982 from the middlelate Cenomanian of England (Weaver 1982), has thicker ridges overall.
