Judicial opinion 128

Abstract

Judicial Opinion 128 addresses nomenclatural issues related to the names of classes validly published under the International Code of Nomenclature of Prokaryotes. It is confirmed that the common ending -proteobacteria of some class names is not indicative of a joint taxonomic or phylogenetic placement; that the nomenclatural type of Mollicutes Edward and Freundt 1967 (Approved Lists 1980) is Mycoplasmatales Freundt 1955 (Approved Lists 1980); and that the placement of a name on the list of rejected names does not imply that another name with the same spelling but a distinct rank is also placed on that list. The names at the rank of class Anoxyphotobacteria (Gibbons and Murray 1978) Murray 1988, Archaeobacteria Murray 1988, Bacteria Haeckel 1894 (Approved Lists 1980), Firmibacteria Murray 1988, Microtatobiotes Philip 1956 (Approved Lists 1980), Oxyphotobacteria (ex Gibbons and Murray 1978) Murray 1988, Photobacteria Gibbons and Murray 1978 (Approved Lists 1980), Proteobacteria Stackebrandt et al. 1988, Schizomycetes Nägeli 1857 (Approved Lists 1980), Scotobacteria Gibbons and Murray 1978 (Approved Lists 1980) are placed on the list of rejected names. For three common nominative singular suffixes of genus names their genitive singular and nominative plural forms are confirmed: -bacter (-bacteris, -bacteres); -fex (-ficis, -fices); and -genes (-genis, -genes). The class names Aquificae Reysenbach 2002, Chrysiogenetes Garrity and Holt 2002, Chthonomonadetes Lee et al. 2011, Gemmatimonadetes Zhang et al. 2003, Opitutae Choo et al. 2007 and Verrucomicrobiae Hedlund et al. 1998 are orthographically corrected to Aquificia, Chrysiogenia, Chthonomonadia, Gemmatimonadia, Opitutia and Verrucomicrobiia, respectively.
