Reticulocosta edrianae n. sp. is similar to Reticulocosta tarfayensis (Reyment, 1978), even presenting some degree of intraspecific variation on the reticulate ornamentation, like the latter (see Reyment, 1978; Andreu-Boussut, 1991; Majoran, 1991). Even so, the aforementioned species, plus Reticulocosta vitiliginosa (Apostolescu, 1961), differ from the present species by its overall lesser presence of reticulation and sharper ridges, when compared to them (see Apostolescu, 1961). In addition, Reticulocosta edrianae n. sp. has its occurrence restricted to the Lower Cretaceous (Albian), while the others are Upper Cretaceous species (upper Cenomanian-Santonian).
