Description Diagnosis: Test large, conical, uniseriate. Chambers inflated. Wall thick with a calcareous agglutinate. Aperture terminal, areal, simple.
Occurrence: Latest Tournaisian (MFZ7 and basal part of MFZ8) of Palaeotethys, Urals and Perigondwana Provinces (Devuyst, 2006, p. 33). “V1a” in Belgium (Groessens et al., 1977) and Germany (Mansourian, 1979).

Diagnosis Test large, uniserial, and rectilinear to slightly arcuate, consisting of a few rapidly enlarging globular to ovate chambers that enclose the terminal end and neck of the preceding chamber, sutures strongly constricted; wall calcareous, granular, with calcite inclusions, probably due to recrystallization of the wall, and possibly with some agglutinated particles, thick, particularly in the region of the neck; aperture terminal, simple, rounded, at the end of the prominent neck. L. Carboniferous (L. Visean); USSR: Urals. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
