Natica (Glyphepithema) cayennensis : Warmke & Abbott, 1961: 96-97 (pl. 3e, 17f); Rios, 1970: 65-66 , 1975: 68 (pl. 19, fig. 274), 1985: 68 (pl. 24, fig. 300), 1994: 81 (pl. 27 fig. 314), 2009: 145 (fig. 345); Abbott, 1974: 159 (fig. 1717). Naticarius cayennensis : Simone, 2011: 269 , 276, 283, 290, 297, 304 (figs. 15, 20). Stigmaulax cayennensis : Rosenberg et al., 2009: 638 ; MolluscaBase, 2023. Type locality: Cayenne [ French Guiana ]. Remarks: Recently, Naticariuscayennensis hasbeenreclassified into the genus Stigmaulax Mörch, 1852 , and formerly into the subgenus Glyphepithema Rehder,1943 (refer to synonymy above).However, phylogenetic studies,partially published in Simone (2011) , reveal that N. cayennensis is the sister taxon of Naticarius canrena ( Linné, 1758 ) , the type species of this genus.This close relationship is based on anatomical similarities, as well as attributes of the shell, radula, and operculum.These factors provide justification for the suggested combination herein.
