Diagnosis Test free, flaring, rhomboidal in section, lateral margins acutely angled, broad and low chambers biserially arranged throughout, sutures depressed, oblique; wall finely agglutinated; aperture a low interiomarginal arch in the early stage, later with one or two additional areal openings above the basal one, the multiple openings may fuse to produce a very high and narrow slitlike opening extending up to one-third the distance across the terminal surface of the chamber, its scalloped margin reflecting the origin from separate openings. M. Eocene to L. Miocene; New Zealand. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
