Semicassis iheringi (Carcelles, 1953) revalidated, new stratum
Remarks: The species has been previously considered both a subspecies of Semicassis labiata (Perry, 1811) or a synonym of S. labiata zeylanica (Lamarck, 1822) , taxa described in the Indo-Pacific region.In an ongoing study on Tonnoidea , samples of Semicassis from Brazil, Australia, and New Zealand were compared, revealing significant anatomical differences among them. These differences support the separation of these populations at the species level, with the Brazilian population identified as S. iheringi , and those in the Southwest Pacific region identified as S. zeylanica and S. labiata . While all the data are still being prepared for publication, this preliminary evidence suggests that S. iheringi should be treated as a separate and valid species from now on.
