The classification is based upon: ATLAS OF PALEOCENE PLANKTONIC FORAMINIFERA by Richard K. Olsson, Christoph Hemleben, William A. Berggren, Brian T. Huber, Editors and MEMBERS OF THE PALEOGENE PLANKTONIC FORAMINIFERA WORKING GROUP
Acarinina is described as having "coarse pustules (muricae) which become dense, enlarged and spike-like on the umbilical surface around the aperture", which somehow resembles the lower part.
