Diagnosis
ReferenceDiagnosis
J. Jin 2012Shell 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).
