Type species
Cossmann stated the type species of ''Epalxis'' to be ''Pleurotoma crenulata''
Lamarck, 1804; however he used the latter name in the sense of Deshayes (1834). ''P. crenulata'' in the sense of Deshayes and Cossmann is in fact ''Pleurotoma ventricosa''
Lamarck, 1804. Brebion
992, Cossmanniana, Hors-série 1accepted ''P. ventricosa'' as the type species of ''Epalxis'', and Tracey et al. (2019) accepted Brebion's type species fixation under Art. 70.3 and 86.1.1 of the Code. However, Art. 70.3 cannot be applied retroactively to Brebion's type species fixation. Tracey et al. should have invoked Art. 70.3 in their own right if they chose to do so. For the time being, this leaves ''Pleurotoma crenulata''
Lamarck, 1804, as the type species of ''Epalxis'' by OD.
