Belongs within: Rosalinida.
The Eponididae are a group of free-living Foraminifera known from the Palaeocene to the present day. In the genus Eponides, the primary aperture is an interiomarginal arch without an internal tooth plate (Loeblich & Tappan 1964).
Characters (Loeblich & Tappan 1964): Test free, low trochospiral coil or may be uncoiled; aperture basal or areal, single or multiple, may be covered by plate or spongy material.
