Diagnosis Low conical test with slightly concave base, apically located embryonal apparatus consisting of simple protoconch and septulate deuteroconch, primary chambers discoidal and rectilinear, a relatively wide marginal zone subdivided by radial vertical exoskeletal beams that produce elongated chamberlets, beams of successive chambers being vertically aligned rather than alternating in position and with horizontal exoskeletal rafters, the short beams and rafters forming many small chamberlets in the marginal zone, central zone filled with small endoskeletal pillars that alternate in position from chamber to chamber, rather than being aligned. L. Cretaceous (Barremian to Aptian); Italy: Sardinia; China: Xizang Prov. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
