J.P. Euzéby: List of Prokaryotic names with Standing in Nomenclature

Number of published names

Contents:

Introduction:

The International Code of Nomenclature of Bacteria (1990 Revision) states that the name of a taxon is validly published, and therefore has standing in nomenclature:
. if it is cited in the Approved Lists of Bacterial Names,
. or if it is published in papers in the International Journal of Systematic Bacteriology or in the International Journal of Systematic and Evolutionary Microbiology and conforms to requirements laid down in the Bacteriological Code,
. or if it is validly published by announcement in a Validation List.

In addition to valid publication of a name, the Bacteriological Code (1990 Revision) also states that only correct names are to be used, i.e. based on legitimacy and priority of publication.

Notes:

C) Four subgenera are validly published: Acetobacter (subgen. Acetobacter Beijerinck 1898), Acetobacter (subgen. Gluconoacetobacter Yamada and Kondo 1985), Moraxella (subgen. Branhamella Catlin 1970), and Moraxella (subgen. Moraxella Lwoff 1939). However, the category subgenus is not in current use. So, the subgenera and species included in these subgenera are not cited in the records.

D) Names of taxa above the rank of class and Candidatus (taxonomic categories not covered by the Rules) are outside the scope of the Bacteriological Code (1990 Revision). However some taxa above the rank of class and some Candidatus names have been published in IJSB/IJSEM and they are included in the records (see: Names of taxa above the rank of class and Candidatus).

E) There is no validly published name for the categories "subfamily" and "subtribe".

Two divisions were included in the Approved Lists. However, the category Divisio is not covered by the Rules and the divisons are not included below.
. Classes: 7
. Subclasses: 1
. Orders: 21
. Suborders: 3
. Families *: 66
. Tribes: 24
. Genera: 290
. Species **: 1,792
. Subspecies: 131

. Names validly published (year and taxonomic category):

III. Names of taxa above the rank of class (taxonomic categories not covered by the Rules)

The taxonomic categories above the rank of class are not covered by the Rules of the Bacteriological Code (1990 Revision) [Rule 5b]. However, two divisions were included in the Approved Lists of Bacterial Names, two divisions were cited on Validation List n° 15, several taxa proposed by Cavalier-Smith (Int. J. Syst. Evol. Microbiol., 2002, 52, 7-76) appear in the Notification List published in the March 2002 issue of the IJSEM (Int. J. Syst. Evol. Microbiol., 2002, 52, 293-295), nine phyla (= divisions) are cited in Validation List n° 85, one phylum cited in the July 2003 issue of the IJSEM appears in the Notification List published in the November 2003 issue of the IJSEM (Int. J. Syst. Evol. Microbiol., 2003, 53, 1703-1705), one phylum appears in Validation List 98, one phylum is cited in the Validation List n° 106, two phyla are proposed in the 2009 issues of the IJSEM, one phylum is cited on Validation List 132, one phylum is cited in the June 2010 issue of the IJSEM, and one phylum is cited in the June 2011 issue of the IJSEM.
These names are outside the scope of the Bacteriological Code (1990 Revision) and they have no standing in bacterial nomenclature. See the file ¤ "Taxa above the rank of class".

- Kingdom (regnum): 1
- Subkingdom (subregnum): 2
- Infrakingdom (infraregnum): 2
- Superdivision (superdivisio): 1
- Subdivision (subdivisio): 9
- Superclass (superclassis): 2
- Total: 17

. Total: 51

IV. Candidatus (taxonomic category not covered by the Rules)

The category Candidatus is not covered by the Rules of the Bacteriological Code (1990 Revision). During the 1996 meetings in Jerusalem, the Judicial Commission unanimously voted to recommend to the ICSB (now ICSP) that this taxonomic category be adopted as an Appendix to the Bacteriological Code (1990 Revision). Thereafter, the proposal of the Judicial Commission was unanimously accepted by the ICSB (now ICSP). See the file ¤ "List of Candidatus".

- Candidatus (published in the IJSB/IJSEM): 106

The number of names is 65 in the Approved Lists of Bacterial Names and 66 in the Amended Edition of the Approved Lists of Bacterial Names. This difference is linked to the status of the family name Enterobacteriaceae.
The family name ¤ Enterobacteriaceae Rahn 1937 was omitted from the body of the Approved Lists of Bacterial Names 1980, but a footnote was inserted on page 236 indicating that the name was sub judice, referring to the proposal by Lapage. This has led to some confusion over the status of the name. The Judicial Commission has reviewed this question and concluded that the family name Enterobacteriaceae Rahn 1937 is valid and should have been incorporated in the body of the Approved Lists of Bacterial Names 1980. So, this nomenclature is listed in the Amended Edition of the Approved Lists.

**:

The Approved Lists of Bacterial Names and the Amended Edition of the Approved Lists of Bacterial Names did not included the name Rhodococcus sputi which was published by Tsukamura (1978) in the International Journal of Systematic Bacteriology [1]. In view of the fact that the name was not included in the Approved Lists, Tsukamura and Yano revived the name Rhodococcus sputi: Rhocococcus sputi (ex Tsukamura 1978) Tsukamura and Yano 1985 [2]. However, according to Rule 24a, Note 1, the name Rhodococcus sputi Tsukamura 1978 is to be treated as being included in the Approved Lists and this name has priority over Rhodococcus sputi (ex Tsukamura 1978) Tsukamura and Yano 1985 [3].

***:

3,1164 nomenclatural changes have been published in Validation Lists. However, only 3,090 names are included in the records for the following reasons:
. The 23 names listed in the Validation Lists 1, 2 and 3 have been included in the Approved Lists of Bacterial Names (see the file ¤ "Names validly published by announcement in a Validation List").
. Nineteen names are listed twice: Actinokineospora, Actinokineospora riparia, Bifidobacterium saeculare, Clostridium puniceum, Brevibacterium casei, Brevibacterium epidermidis, Enterococcus sulfureus, Halobacterium mediterranei, Methanothrix thermoacetophila, Nitrobacter alkalicus, Nitrospira, Nitrospira marina, Planctomycetaceae, Planctomycetales, Rhodococcus opacus, Staphylococcus chromogenes, Tetragenococcus, Tetragenococcus halophilus, and Thermus scotoductus.
. The taxonomic categories above the rank of class are not covered by the Rules of the Bacteriological Code (1990 Revision) [Rule 5b]. However, two divisions are cited on Validation List n° 15, nine phyla (divisions) are cited in Validation List n° 85, one phylum is cited in Validation Lisy n° 98, one phylum cited in Validation List n° 106, one phylum cited in Validation List n° 132, and seven phyla are cited in Validation List n° 143. These names are not included in the table.
. Thermus profundus Kobayashi et al. 1995 (validation list n° 52) is an orthographically incorrect name and it is not included in the records (the correct entry, Thermococcus profundus Kobayashi et al. 1995, appears in validation list n° 53).
. Thermodesulfobacterium mobile (Rozanova and Khudyakova 1974) Rozanova and Pivovarova 1991 (validation list n° 36) is an illegitimate name and it is not included in the table.
. Crinalium epipsammum De Winder et al. 1991 is not validly published under the Rules of the Bacteriological Code (1990 Revision) and it is not included in the table.
. One emendation is cited in Validation List n° 26 (Actinoplanes Couch 1950 (Approved Lists 1980) emend. Stackebrandt and Kroppenstedt 1988) and it is not included in the records.
. Two entries are names cited as synonyms (Sphingobacterium spiritivorum (Holmes et al. 1982) Yabuuchi et al. 1983 pro synon Flavobacterium yabuuchiae Holmes et al. 1988, and Serpulina Stanton 1992 pro synon. Brachyspira Hovind-Hougen et al. 1983) and they are not included in the records.
. Nematospora sinecauda is cited in validation list n° 25. However, Nematospora sinecauda is a yeast and it is not included in the records.
. Acetobacter (subgen. Acetobacter, Acetobacter (subgen. Acetobacter) aceti, Acetobacter (subgen. Gluconoacetobacter), Acetobacter (subgen. Gluconoacetobacter) liquefaciens are cited in Validation List n° 17. However, the category subgenus is not in current use. So, the subgenera and the species included in these subgenera are not  cited in the table.
