Taxonomy:
Distinguishing features: Small cylindrical Scyphosphaera with narrow circular base
Original description: Diagnosis: A lophadolith in which the wall extends from a circular proximal base at an angle outwards a short distance and then vertically upwards.
Description: This small species of Scyphosphaera has a circular and flat proximal base with a short but distinct outward jutting edge. A cylindrical wall extends from the edge and terminates without any outer flaring or inward curvature. The outer surface of the wall is heavily ornamented. The minimum diameter of the species lies at the proximal base.
