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 | |
|---|---|---|
| J. Jin et al. 2006 | Medium-sized, elongate, ventribiconvex shells, with high, rostrate ventral umbo; ventral and dorsal interareas relatively large, well defined; ventral sulcus and dorsal fold weak to moderately developed; delthyrium open. Costae subrounded, unequal in size, increasing anteriorly by bifurcation. Spondylium extending for one-half to two-thirds of shell length, V-shaped in cross section, bearing incipient comb structure at distal end; median septum extending for one-half shell length. Inner hinge plates very short, subparallel to, or basolaterally divergent, from each other towards valve floor; outer hinge plates longer. Crura rodlike, slightly longer than spondylium. |
