Remarks

The genus Arasella is somewhat problematic because of its very simple suture line; an unambiguous attribution to a distinct family is therefore difficult. The shape of the external lobe rather speaks for placing it in the family Xenodiscidae rather than the Dzhulfitidae . The shape of the conch and the sculpture are similar to the early Changhsingian Shevyrevites , but this genus has multidentate adventive and lateral lobes.
