Diagnosis Proloculus followed by undivided enrolled tubular second chamber, evolute, whorls aligned, central stellate region present but outer whorls without complexity and no secondary deposits; wall with reduced inner microgranular layer and reduced outer hyaline radial layer covering all whorls but lacking any umbilical masses; aperture simple, at the open end of the tubular chamber. L. Carboniferous (L. to M. Visean); USSR; North America. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
