Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Bilotta 2010 | Compressed platycone shells, with evolute or very evolute inner whorls and involute to moderately involute outer whorls. Sub-elliptic whorl section, higher than wide. In internal moulds the phragmocone can be smooth or in some instances ribbed; when the test is preserved, the flank shows sinuous striae which can cross the venter, where they fade, forming a weak chevron. On the body chamber, biconcave constrictions can be present and sometimes also more or less
sinuous ribs or hemi-ribs due to the bundling of striae, which near the ventro-lateral edge originate short cuneiform tuberclespines. The body chamber is apparently long about threequarters of whorl; the peristome is not known with certainty, but it should substantially repeat the course of constrictions and striae. Suture from pseudoceratitic to poorly indented with non arborescent lobes; E lobe with transversal cut; L bifid or bitrifid, nearly as large as U2 or more; LS1 saddle usually more advanced than ES; sub-lituid embracing I lobe |
