Advena grayi (Sykes, 1900:141)
Taxonomy & Nomenclature
Detailed synonymy (following Hyman et al., 2024:S1 Appendix): Fretum grayi Sykes, 1900: 141, pl. 13, figs 6-7; Mathewsoconcha grayi: Iredale, 1945: 67; Advena grayi: Hyman, Caiza & Köhler, 2023: 429; Belloconcha elevata Preston, 1913: 529; Iredale, 1945: 67, pl. 5, figs 13-15; Mathewsoconcha elevata: Smith, 1992: 237
Previously considered a synonym of M. suteri (Smith, 1992; MolluscaBase, 2022), but it was reportedly rediscovered in November 2022 (Power, 2022). It is now considered a valid species in the genus Advena (Hyman et al., 2023, 2024).
