Diagnosis Test trochospiral and planoconvex in the early stage, chambers rapidly broadening to become crescentic and coarsely perforate on the spiral side, umbilical side imperforate with radial sutures, later chambers added in cycles, the chambers having lateral apertures; the gamont generation during gamogony produces a balloon chamber and enclosed float chamber like those of Cymbaloporetta but of greater complexity, the imperforate inner float chamber is fused to the wall of the similarly imperforate balloon chamber except where peripheral infolding forms branching channels, arching of the balloon chamber over the branching channels of the float chamber produces branching tubes, reflected externally as ridges that each terminate in a rounded aperture, the tubes that radiate from the apertures of the trochospiral test to the external openings of the balloon chamber providing multiple pathways for cytoplasm and gametes. Holocene; Pacific Ocean and Indian Ocean. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
