Abstract

The only species of Polyplacophora known from the Eocene of Gant is Tonicia pannonica. Re-examination of the type material of this species indicates that the two syntypes of Szőts belong to two different species. One of those syntypes (the tail valve) is designated as lectotype herein, in order to provide stability to nomenclature by preserving the generic attribution of the species pannonica to the genus Tonicia. New samples were collected near the type locality, and the nearly 200 valves recovered belong to four species: Tonicia pannonica, Lepidochitona gantensis sp. nov., L. szoetsi sp. nov., and L. viciani sp. nov. The paralectotype of Tonicia pannonica, an intermediate valve, is here excluded from that species and attributed to Lepidochitona szoetsi sp. nov
