Clarification on the name-bearing type designation of several cyclophorid species (Mollusca, Gastropoda) by H. H. Godwin-Austen (1915)

Abstract

The type series boundary and the name-bearing type designation of each cyclophorid taxon originally described by Godwin-Austen are clarified based on an interpretation that complies with the ICZN. Previous statuses of type specimens designated by previous authors are reconsidered. Lectotypes of <jats:italic>Spiraculum oakesi</jats:italic> Godwin-Austen, 1915, <jats:italic>Spiraculum kempi</jats:italic> Godwin-Austen, 1915, <jats:italic>Pterocyclos aborensis</jats:italic> Godwin-Austen, 1915, <jats:italic>Pterocyclos miriensis</jats:italic> Godwin-Austen, 1915, <jats:italic>Pterocyclos brahmakundensis</jats:italic> Godwin-Austen, 1915, <jats:italic>Spiraculum luyorensis</jats:italic> Godwin-Austen, 1915, <jats:italic>Spiraculum putaoensis</jats:italic> Godwin-Austen, 1915, and <jats:italic>Theobaldius oakesi</jats:italic> Godwin-Austen, 1915 are here designated to stabilize the existing nomenclature. In addition, the type specimens of <jats:italic>Pterocyclos miriensis</jats:italic> and <jats:italic>Theobaldius oakesi</jats:italic> are photographed and figured for the first time.
