Chapter 12: Homonymy


Article 57. Species-group names.

57.1. Application of the Principle of Homonymy to names of species and subspecies. The Principle of Homonymy applies to species-group names that are or are deemed to be spelled identically [Art. 58] and are published originally or subsequently in combination with the same generic name [Art. 53.3], including names of collective groups and of ichnotaxa at genus-group level [Arts. 10.3 and 42.2.1].

57.2. Primary homonyms. Identical species-group names established for different nominal taxa when originally combined with the same generic name (see also Articles 11.9.3.2 and 57.8.1) are primary homonyms [Art. 53.3] and the junior name is permanently invalid (but see Article 23.9.5) except when:

Examples. The following are primary homonyms: Culex affinis Stephens, 1825 and Culex affinis Adams, 1903; Lycaena argus nevadensis Oberthür, 1910 and Lycaena nevadensis Zullich, 1928; Aporia hippia transiens Alpheraky, 1897 and Aporia crataegi transiens Lempke, 1953.

57.3. Secondary homonyms.

57.4. Subgeneric name irrelevant. The presence of different subgeneric names placed in parentheses between the same generic name and identical species-group names is irrelevant to the homonymy between the names concerned.

Example. The specific names of Aus (Bus) intermedius Pavlov and Aus (Cus) intermedius Dupont were both originally established in the genus Aus, and so are primary homonyms. The specific name of Aus (Dus) intermedius (Nomura) was originally established in the genus Xus, and so is a secondary homonym of the species names of both Aus (Bus) intermedius and Aus (Cus) intermedius.

57.5. Difference in spelling of generic names. Identical species-group names (or species-group names deemed to be identical [Art. 58]) established for different nominal taxa are homonyms when combined with the same generic name (but see Article 57.8.1) even if the spelling of the generic name with which one or more of the species-group names is combined is an incorrect spelling or an emendation [Art. 11.9.3.2].

57.6. One-letter difference. Except as specified in Article 58, a one-letter difference between species-group names combined with the same generic name is sufficient to prevent homonymy.

57.7. Precedence of names of species over those of subspecies. Of two homonymous species-group names of identical date, one established for a species takes precedence over one established for a subspecies [Art. 24.1] or over one deemed to be of subspecific rank [Art. 45.6].

57.8. Exceptions.
