Diagnosis Test conical, similar to Palorbitolina in structure but with embryonal apparatus at one side of the apex and consisting of globular proloculus and a lateral chamber, later uniserial and discoidal chambers with differentiated marginal zone having strongly developed vertical radial beams or septula, and central zone with more labyrinthine arrangement, rather than with pillars. L. Cretaceous (Barremian); France. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
