Diagnosis Test planispiral and evolute, flattened, of medium to large size, numerous narrow chambers in many rapidly expanding whorls, sutures strongly curved back at the periphery, septal flap moderately to strongly folded laterally, the folds alternating in position with the septal stolons, marginal cord with numerous superposed marginal canals, intraseptal canal system with symmetrical lateral canals and sutural canals that are strongly curved forward on the lateral wall to open in the zone of interseptal pillars, proximal row of sutural canals vertical, forked, or branching and distal row branching and inclined in the direction of growth, leading from the lateral intraseptal canal in the fold of the septal flap obliquely across the perforate lateral wall and opening into the median zone of the chamber surface between the pores and interseptal pillars, multiple secondarily formed simple supplementary stolons are radial, arranged regularly in the median plane and alternating with the folds of the septal flap; wall calcareous, lamellar, finely perforate, surface may be smooth or pustulose, with numerous septal and cameral pustules; interseptal foramen formed by resorption at the base of the septal face. Oligocene to Holocene; cosmopolitan subtropical. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
