ringicula, Nassa [ Tritia pygmaea (Lamarck, 1822) ] ( Figures 21K, L )

1890c: 185 [XXXVIII c: 919]—available name

Type material. MCZR–M–18093 —2 sh “ N. ringicula Monts in Conch. Prof. Pal. —Nat. Sic. 1890 p. 25 S. Vito”. Type locality. Described from San Vito lo Capo (Sicily) .

Remarks. Recorded by MolluscaBase (2018) as taxon inquirendum. This taxon was based on specimens with a protoconch wider than Tritia pygmaea as commonly conceived. It may just represent a different phenotype, or a cryptic distinct species, and we provisionally keep the most conservative position [new synonymy].
