Diagnosis Test conical, up to about 1.6 mm in height, megalospheric generation forming a narrow cone, up to 1.2 mm in maximum diameter, microspheric generation larger and more spreading, with maximum diameter up to 3.8 mm; simple megalospheric proloculus at the test apex followed by a few semilunate chambers, and then by many uniserial discoidal chambers of rapidly enlarging diameter; microspheric generation apparently uniserial immediately following the proloculus, final chambers of the spreading test annular; exoskeleton consists of the thick peripheral wall and numerous elongate radial beams subdividing the chamber interior, one or two shorter beams intercalated between adjacent major ones in the marginal zone, a single horizontal rafter near the periphery of each chamber, midway between chamber floor and roof, subdivides the marginal zone; wall agglutinated, endoskeletal chamberlets formed by the undulating ends of the radial beams that join in the chamber interior to produce a reticulate structure, chamberlets alternating in position from chamber to chamber; aperture of numerous round openings at the center of the apertural face, leading obliquely inward and alternating in position from chamber to chamber but absent from the marginal zone. U. Cretaceous (Campanian); Spain. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
