If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. M. Larsson et al. 2014 | Emended diagnosis. Sclerites microscopic, apatitic by original composition, growing via basal-internal accretion.
Scleritome comprising at least three clearly distinctive sclerite types: symmetrical sclerite types S1 and S2 and laterally compressed asymmetrical L sclerites. S1 sclerites pyramidal with posterior triangular notch and U-shaped anterior plate. S2 sclerites concave and acutely triangular. External surface with micro-ornament consisting of polygonal compartments. Scleritome consisting of one S2 sclerite nested within triangular notch of one S1 sclerite; multiple L sclerites lining antapical margins in additional rows forming an open tube. It differs from Eccentrotheca by the presence of two specialized bilaterally symmetrical sclerites in the scleritome and the distinct polygonal external micro-ornament. Differs from Kulparina by more regular and less compressed sclerite shape and the distinct polygonal external micro-ornament. Differs from Sunnaginia by the presence of individual sclerite types, the bilateral symmetry of S1 and S2 sclerites and the absence of right- and left-hand sclerite pairs, polygonal micro-ornament and the shell microstructure. |
