Chapter 12: Homonymy


Article 55. Family-group names.

55.1. Application of the Principle of Homonymy. The Principle of Homonymy applies to all family-group names, including names of ichnotaxa at the family-group level.

55.2. Homonymy from identical generic names. See Article 39.

55.3. Homonymy from similar generic names. Homonymy between family-group names may result from similarity but not identity of the names of their type genera.

55.4. One-letter difference. Even if the difference between two family-group names is only one letter, they are not homonyms.

Example. The family names LARIDAE (Aves), based on Larus Linnaeus, 1758, and LARRIDAE (Hymenoptera), based on Larra Fabricius, 1793, differ by one letter and are not homonyms.

55.5. Precedence of names at higher rank. Of two homonymous family-group names of identical date but established at different ranks, the one established at the higher rank is deemed to be the senior homonym [Art. 24.1].
