Heliacus d’Orbigny, 1842 (Mollusca, Gastropoda): proposed conservation

The purpose of this application, in reference to Article 24.2.5 of the Code, is to establish priority of the generic name Heliacus d’Orbigny, 1842 over Torinia Gray, 1842 (Mollusca, Gastropoda, ARCHITECTONICIDAE). The two nominal genera are subjective synonyms both published in the same year, but their relative priority remained unresolved. As a consequence both Heliacus and Torinia have been used in the literature, but Heliacus has predominant usage and Torinia seems to have been used only twice in the last 24 years. Evidence supports priority of the name Heliacus established by action of the First Reviser; however, suppression of the name Torinia is proposed to ensure stability.
