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.
|J. Jin 2012||Shell subcircular, ventribiconvex in adults; multicostellate to weakly fascicostellate, with medial line of dorsal valve marked by interspace. Punctae differentiated into two sizes; aditicules absent. Dental plates divergent posteriorly, becoming subparallel anteriorly to serve as lateral bounding ridges of small, cordate muscle field. Cardinal process delicate, with bilobate myophore; brachiophore plates inclined baso-medially; fulcral plates normally present (emended Jin and Bergström 2010).|
