Revision of Hyperaulax

Freshly pressed: a paper by Salvador & Cavallari on the Brazilian genus Hyperaulax. “The genus Hyperaulax Pilsbry, 1897 comprises two living species endemic to the oceanic Fernando de Noronha Archipelago, offnorth-eastern Brazil. They are currently allocated in two subgenera, Hyperaulax s. str. and Bonnanius Jousseaume, 1900, belonging to the family Odontostomidae. Herein we present a taxonomic revision of these species, assessing their familiar allocation within Orthalicoidea, offering updated diagnoses and descriptions, figuring the type materials and further relevant specimens, and providing barcoding DNA sequences. We conclude that Bonnanius is a junior synonym of Hyperaulax, which is classified in Odontostomidae.The genus contains two valid species, H. ridleyi and H. ramagei, both endemic to Fernando de Noronha“.

This genus has been associated also with Floridian fossils for many years, until Auffenbach et al. showed that these fossils belonged to the Bulimulidae. This revision of the two species neatly shows that subgeneric splitting should be avoided.
