Nomenclature When they described Callostracon tyrrhenicum, Smriglio & Mariottini combined the specific epithet with Callostracon as used by Nordsieck (1972). The latter, however, is a misspelling of Colostracon Hamlin, 1884, a genus of Mesozoic caenogastropods unrelated to the Recent Mediterranean species. Recognizing this situation, Repetto & Bianco established the name Callostracon for the Mediterranean species. Callostracon Repetto & Bianco, 2012, is not a junior homonym of "Callostracon" as used by Nordsieck, as the latter is an incorrect subsequent spelling, and thus not a nomenclaturally available name.
Species Callostracon amabile (R. B. Watson, 1883) Callostracon chariis (R. B. Watson, 1883) Callostracon tyrrhenicum (Smriglio & Mariottini, 1996)
