subfamilia_authority = Coovert and Coovert, 1995"Persiculinae" is a
taxonomic subfamily of minute to smallpredatory seasnail s, marinegastropod mollusk s. This subfamily includes several species which aremicromollusk s.The subfamily is sometimes placed in the family
Cystiscidae , and is sometimes instead left in the familyMarginellidae the margin snails. It is within the infraorderNeogastropoda .(Note: Gastropod
taxonomy has been in flux for more than half a century, and this is especially true currently, because of new research inmolecular phylogeny . Because of all the on-going changes, different reliable sources can yield very different classifications.)Shell description
