  • 🧍 On the Notification List in the April 2018 issue of IJSEM, the List Editors state that the names Clavibacter capsici, Clavibacter insidiosus, Clavibacter nebrasksensis, Clavibacter sepedonicus and Clavibacter tesselarius proposed by Li et al. are illegitimate as they contravene Rule 34a and 50a of the International Code of Nomenclature of Prokaryotes. The use of illegitimate names contravenes Rule 51a. Objection: Tindall (2019). Publication: Tindall BJ. The role of incorrect citation of the International Code of Nomenclature of Prokaryotes and subsequent misinterpretation in causing unnecessary nomenclatural confusion.
