Morrison H.M., Kirkendale L.A. & Wilson N.G. 2020. A review of extant Tudivasum Rosenberg & Petit, 1987 (Neogastropoda: Turbinellidae) and description of three new species from Western Australia. Journal of Molluscan Studies 87(1): eyaa030. DOI:10.1093/mollus/eyaa030
Résumé [+] [-]Tudivasum Rosenberg & Petit, 1987 is a morphologically distinct gastropod genus of low diversity. All but one species are known from Australia and they occur from the intertidal zone down to hundreds of metres on the continental shelf. These carnivorous gastropods are thought to have intracapsular development. The six currently recognized extant species are reviewed here and their geographical ranges clarified. Two new species, Tudivasum chaneyi n. sp. and T. ashmorense n. sp., are described from Ashmore Reef, Western Australia, and are characterized by differences in protoconch colour and shell sculpture. The third new species, T. westrale n. sp., is described from the mid-west coast of Western Australia, where it has long been misidentified as T. spinosum (H. Adams & A. Adams, 1864). We generated a molecular phylogeny based on mitochondrial DNA sequence data to test morphological species concepts and reconstruct relationships among four of the described species. High levels of divergence within one of the new species could indicate an additional cryptic species.
