Diagnosis Test planispiral, bilaterally symmetrical, commonly involute although larger microspheric individuals may become only partially involute in the later stage, chambers numerous and enlarging rapidly, sutures distinct, may be elevated, radial near the umbilici but strongly curved back at the periphery, canal system opening along the lateral chamber sutures in a single row of pores, intraseptal canal system repeatedly branching at the periphery to envelop the peripheral part of the chamber, periphery carinate and with a few canaliculate spines; wall calcareous, finely perforate, optically radial, numerous somewhat irregular ridges on the proximal part of the chamber surface, perpendicular to the suture and parallel to the periphery, and may bifurcate before dying out toward the anterior face of the chamber, vertical ridges also extend a short distance up the apertural face from its base; aperture consists of a row of pores near the base of the apertural face. Oligocene to Holocene; Australia: New South Wales, Victoria, Tasmania. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
