Proposals to emend Rules 8, 15, 22, 25a, 30(3)(b), 30(4), 34a, and Appendix 7 of the International Code of Nomenclature of Prokaryotes

Abstract

To complete the ongoing revision of the International Code of Nomenclature of Prokaryotes, we here propose emendation of Rules 8, 15, 22, 25a, 30(3)(b), 30(4), 34a and Appendix 7. These proposed emendations deal with: the nomenclatural type of taxa above genus; the suitability of names published in supplementary material or in papers published on e-print servers for effective publication; the number of culture collection designations to be included in an effective publication of a name of a species or subspecies to qualify for validation of the name; the kinds of restrictions that may be attached to deposits of type strains; and the question whether elevation of a subspecies to the rank of species or lowering of a species to the rank of subspecies establish new combinations. Some of these emendations change the meaning of the Code while others are mere textual clarifications.
