Description
Cerioid, with lonsdaleoid dissepimentarium; with lathlike columella continuous with one, or two opposite, major septa; no wall-forming axial tabellae noted in figured type specimen, nor any radial septal lamellae; tabular floors subhorizontal, more commonly slightly convex or in places updrawn at columell; a few slightly concave; fossula not distinct. [Diagnosis based only on lectotype. Older names Petalaxis MILNE-EDWARDS & HAIME, 1852, which see, and Acrocyathus D'ORBIGNY, 1849, Lithostrotionina, Lithostrotionidae, Acrocyathinae, are available for species with different morphologies commonly attributed to Lithostrotionella; because knowledge of the range of variation in L. unica is lacking, it is recommended that the name Lithostrotionella not be used. See also EASTON, 1973, p. 128.]
