On the status of the names Corynebacteriales Goodfellow and Jones 2015, Mycobacteriales Janke 1924 (Approved Lists 1980) and Mycobacteriales Cavalier-Smith 2002.

Abstract

The name CorynebacterialesGoodfellow and Jones 2015 has been validly published by inclusion in Validation List 164, with the nomenclatural type defined as CorynebacteriumLehmann and Neumann 1896 (Approved Lists 1980). The name MycobacterialesJanke 1924 (Approved Lists 1980) appeared on the Approved Lists of Bacterial Names and is validly published, with the nomenclatural type defined as MycobacteriumLehmann and Neumann 1896 (Approved Lists 1980). The name Mycobacteriales Cavalier-Smith 2002 was validly published by inclusion in an article in the International Journal of Systematic and Evolutionary Microbiology with the nomenclatural type defined as MycobacteriumLehmann and Neumann 1896 (Approved Lists 1980). As circumscribed by the authors MycobacterialesJanke 1924 (Approved Lists 1980), Mycobacteriales Cavalier-Smith 2002 and CorynebacterialesGoodfellow and Jones 2015 all contain the genus MycobacteriumLehmann and Neumann 1896 (Approved Lists 1980), which is the nomenclatural type of MycobacterialesJanke 1924 (Approved Lists 1980). Consequently, the name CorynebacterialesGoodfellow and Jones 2015 is not the earliest validly published name, contravenes Rule 51b (1) of the International Code of Nomenclature of Prokaryotes and according to Rule 54 must be replaced. In the case of Mycobacteriales Cavalier-Smith 2002 the status of the name appears to be currently uncertain, but a solution may be in sight.
