Diagnosis Test free, planispiral to slightly asymmetrically coiled, rarely uncoiling, numerous broad and low chambers, whorls enlarging rapidly, sutures depressed, periphery subangular, microspheric tests large and flaring, up to 3 mm in diameter, megalospheric ones somewhat smaller and more nautiloid; wall with imperforate epidermal layer and subepidermal reticular meshwork as in the Choffatellinae, chamber lumen subdivided into chamberlets by somewhat irregular or even bifurcating transverse septula perpendicular to the septa, these being less evenly spaced than in Spirocyclina, septula progressively reduced inward to form discontinuous pillars and finally only small projections, leaving the chambers open in the subcentral zone, but with a more or less continuous median partition resulting from a single elongate median septulum present in successive chambers that divides the test axially into two equal parts; aperture cribrate, the openings irregularly scattered over the slightly depressed central part of the apertural face, and absent from the compact thickened zone at the margins. U. Cretaceous (Coniacian); France. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
