Judicial Opinion 130.

Area of Science:

• Bacteriology
• Nomenclature
• Taxonomy

Background:

• The bacterial genus name Rhodococcus Zopf 1891 (Approved Lists 1980) faced legitimacy questions.
• This genus name was identified as a later homonym of Rhodococcus Hansgirg 1884, a validly published cyanobacterial name.

Purpose of the Study:

• To clarify the legitimacy of the genus name Rhodococcus Zopf 1891.
• To determine if the Judicial Commission could resolve homonym conflicts through name conservation.

Main Methods:

• The Judicial Commission reviewed a Request for an Opinion concerning the nomenclature of Rhodococcus.
• The commission assessed the validity and significance of the conflicting names Rhodococcus Zopf 1891 and Rhodococcus Hansgirg 1884.

Main Results:

• The genus name Rhodococcus Zopf 1891 was confirmed as illegitimate because it is a later homonym of Rhodococcus Hansgirg 1884.
• The Judicial Commission conserved the name Rhodococcus Zopf 1891 over Rhodococcus Hansgirg 1884 due to its greater scientific importance.
• This conservation action rendered Rhodococcus Zopf 1891 legitimate.

Conclusions:

• The genus name Rhodococcus Zopf 1891 is now legitimate following conservation by the Judicial Commission.
• The Judicial Commission possesses the authority to conserve names over earlier homonyms to maintain taxonomic stability.
• This decision ensures the continued use of the significant Rhodococcus genus name in scientific literature.
