Diagnosis Test conical to subcylindrical, with simple embryonal apparatus followed by evolute subapical trochospire, later uncoiled with uniserial discoidal chambers, with marginal zone subdivided into rectangular chamberlets by alternating longer and shorter radial beams, the longer beams continuing into the central zone and secondary ones limited to the marginal zone, beams of successive chambers in vertical alignment; apertural face flat to convex, with smooth marginal zone and central zone that may have approximately radially arranged grooves, apertural pores with small collars, forming a circlet at the junction of the marginal and central zones, as well as scattered over the surface in the central zone, either obliquely piercing the radial plates or passing vertically through the septa between the radial plates. L. Cretaceous (U. Hauterivian to L. Bedoulian); France; Switzerland; Italy: Sardinia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
