Diagnosis Test irregularly discoidal, megalospheric test with spherical proloculus and hemispherical deuteroconch, early stage planispiral and evolute, chambers low, increasing in breadth as added in peneropline fashion, and later becoming annular; wall finely agglutinated, microgranular, with exoskeleton of simple beams and shallow rafters, early structure not well known, but exoskeletal beams present by third chamber, lateral walls not differentiated into epidermis or choffatelloid subepidermal network, endoskeleton nearly completely divides the chamber lumen in the equatorial plane of the test and merges laterally with the exoskeletal beams, being pierced by the unique crosswise oblique stolon system; apertures oblique, aligned in a row on each side of the median plane, those of successive annular chambers alternating in position rather than being radially aligned. U. Cretaceous (Campanian); Spain. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
