The epithet aurantiaca in Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) is illegitimate and requires a replacement epithet. Opinion 89. Judicial Commission of the International Committee on Systematics of Prokaryotes.

Abstract

The Judicial Commission affirms that the combination Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) may not serve as the correct name of the taxon because Rule 12b states that no specific or Subspecific epithets within the same genus may be the same if based on different types and the specific epithet aurantiaca in Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) is the same as the subspecific epithet aurantiaca in Micromonospora carbonacea subsp. aurantiaca Luedemann and Brodsky 1964 (Approved Lists 1980) and the latter has priority. According to Rule 53, the duplication of the same specific or subspecific epithet based on different types creates an illegitimate epithet with the principle of priority determining which is to be replaced as specified in Rule 54. The replacement of the specific epithet aurantiaca in Micromonospora aurantiaca Sveshnikova et al. 1969 (Approved Lists 1980) also requires that the authorship of the original authors is retained. However, action of this nature requires that the original epithet is maintained in the original combination. There currently appears to be no mechanisms where such action can be taken.
