PAGODATROCHUS, A NEW GENUS FOR MINOLIA VARIABILIS H. ADAMS, 1873 (GASTROPODA: TROCHIDAE)
Department of Mollusca, Natal Museum Pietermaritzburg, R.S.A.
Nomenclaturel confusion surrounding the name Minolia variabilis H. Adams, 1873 is clarified. Joint consideration of overall shell morphology and radula structure indicates previous subfamilial and generic referral of the taxon to be incorrect. This necessitates the proposal of Pagodatrochus gen. nov. which is provisionally placed in the Gibbulinae. Trochus mariei Fischer, 1886, and Minolia eutyches Melvill, 1918, are shown to be synonyms. Lectotypes of the following species are designated and figured: M. eutyches, Gibbula holdsworthana G. & H. Nevill, 1871, and Vanitrochus tragema (Melvill & Standen, 1896); the holotype of Trochus mariei is also figured. Minolia charmosyne Melvill, 1918, is synonymised with Gibbula holdsworthana G. & H. Nevill, 1871.
