Cancellaria inermis Pusch, 1837 by subsequent designation of Korobkov (1955) . Middle Miocene , Poland . Discussion. Cancellaria inermis Pusch, 1837 was selected as type species of the genus Inermia by Korobkov (1955) —a genus name that was already preoccupied for the fish genus Inermia Poey, 1860. This lapsus was recognised by Petit and Harasewych (2005) without designating a replacement name. Therefore, in honour of Richard E. Petit, we propose Petitina as new genus name for the preoccupied Inermia .
