Remarks. Name attributed to Peters by Troschel but Köhler & Glaubrecht (2006: 208) considered that Peters was only the collector. By designating the lectotype, Köhler & Glaubrecht (2006: 208) restricted the type locality to Tete, although paralectotypes are also from Sena. Valid species, teste G.B. Sowerby III (1916: 67), who placed it in Lanistes s. str ., and Pilsbry & Bequaert (1927: 196), Brown (1980: 52, 1994: 62) and Berthold (1991: 246), who all placed it in Lanistes subg. Meladomus .
