Genera of family “Clade O”

Cedhagenia

Morphologically, the new genus is most similar to vellaria, notably in the presence in some specimens of a delicate, flared apertural extension. However, this structure is not as well developed as in Vellaria and the overall test shape is more lenticular. Molecular analyses indicate that Cedhagenia is not related related to Vellaria but most closely related to Ovammina.
