Classification and/or Status

Salenioida; Saleniidae; Hyposaleniinae.



Distinguished from other Hyposaleniinae by its non-crenulate tubercles. However, all individuals are small and no material has been examined, so the validity of this taxon is uncertain. It may turn out to be no more than a synonym of Hyposalenia.
