Belongs within: Rotalioidea.
The Elphidiidae are a group of Foraminifera known from the Palaeocene to the present, characterised by a canal system opening to rows of sutural pores. Members of the genus Elphidium have a lenticular test with deeply incised sutures and vertical canals communicating from the umbilical plug to the spiral canals. Cellanthus is a similar genus with a fully developed septal flap (BouDagher-Fadel 2008).
Characters (Loeblich & Tappan 1964b): Test planispiral, trochospiral, or uncoiling; sutural canal system opening into single or double row of sutural pores; wall calcareous, perforate, radial in structure; aperture interiomarginal, single or multiple, or areal.
