Description Solitary corallum. Elliptical calice. Deep calicular platform. Radial elements are compact, free, bicuneiform, straight to curved costosepta. Ornamentation weak but not satisfactorily observable on the strongly silicified lectotype. Radial symmetry possibly hexameral. Bilateral symmetry characterized by the elongated fossa, the elliptical shape of the corallite and the torsion of septa. Endotheca made of vesicular dissepiments sloping down from the parathecal wall to the center of the corallite. [details]

Status Alloiteau (1957, p. 114) created the subgenus Plesiomontlivaltia using the species Montlivaltia inflata as the type species. In addition, however, he grouped the same species with Paramontlivaltia Alloiteau (1957, p. 110) [details]

Comparison Differs from Montlivaltia (Montlivaltia) by the septal ornamentation [details]Description Solitary corallum. Elliptical calice. Deep calicular platform. Radial elements are compact, free, bicuneiform, straight to curved costosepta. Ornamentation weak but not satisfactorily observable on the strongly silicified lectotype. Radial symmetry possibly hexameral. Bilateral symmetry characterized by the elongated fossa, the elliptical shape of the corallite and the torsion of septa. Endotheca made of vesicular dissepiments sloping down from the parathecal wall to the center of the corallite. [details]
Remark Three nominal species were reported (all three by Alloiteau). This subgenus and the double assignation of the type-species to Plesiomontlivaltia (as a subgenus of Montlivaltia) and to Paramontlivaltia (placed in the Smilotrochiidae) demonstrates how the variability of the septal ornamentation in Montlivaltia has never been studied thoroughly enough. The potential use of this subgenus is subordinate to a populational study of intraspecific variability in Montlivaltia [details]
