Taxonomic revision uncovers morphological discrepancies in Pseudolituonella mariae, suggesting its transfer to Gerochella foraminifera.
Pseudolituonella mariae Gendrot from the Santonian of southern France represents the only post-Cenomanian Upper Cretaceous species of the genus. The test morphology, inner and wall structure however are not in conformity with the characteristic features of Pseudolituonella Marie. P. mariae is taxonomically revised and transferred to the genus Gerochella Neagu thereby becoming the second species of the genus besides the lowermost Cretaceous Romanian type-species G. cylindrica. Other specimens of Gerochella described in open nomenclature from the late Maastrichtian of SW Iran show that the genus was widely distributed in Cretaceous shallow-water carbonates.
