Diagnosis Test conical, megalospheric generation with apically located two-or three-chambered simple embryonic apparatus indicated by external sutures, as septa may be secondarily resorbed; later with broad, low rectilinear chambers that increase rapidly in diameter as added, marginal zone of chambers subdivided by numerous fine radial exoskeletal beams, of constant thickness throughout, the somewhat longer major beams alternate with shorter secondary ones, outermost part of the chambers with a single layer of horizontal rafters that together with the numerous beams subdivide the marginal zone into a reticular network, central zone occupied by vertical endoskeletal pillars that thicken toward both chamber floor and roof, where there is a slight tendency to anastomose, pillars narrowest slightly above the floor and appear triangular in axial section; wall of imperforate microgranular calcite; aperture not observed, probably a series of pores on the central part of the final septum. L. Cretaceous (Valanginian); Spain. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
