Diagnosis Test large, discoidal to reniform, microspheric test with a vestigial spire, followed by arcuate uniserial chambers that form £a flabelliform adult test; megalospheric test with large round proloculus followed by a reniform but not distinctly spiral stage; adult chambers evolute and cyclical, lateral zone on each side of the test with exoskeletal beams and rafters producing a thin and delicate subepidermal network, central zone of early chambers undivided, but as the test thickens interseptal pillars appear in the median plane, aligned from one chamber to the next, additional tiers of pillars being added as the test thickens with growth; apertures alternate in position with the pillars within a chamber. Paleocene to M. Eocene; Saudia Arabia; Iraq; Yugoslavia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
