Opis

Diagnosis. — Very shallow conical basal cavity, variously developed platform around the basal cone, apparatus of generalized morphology. 

Remark. — Early species of the genus, with weakly developed platform, are transitional to the probably ancestral species of Pandorinellina, P. vulgaris. The difference between transitional populations is only in the width of the basal cone, in fact, very variable.
