Chapter 9: Genus-group Nominal Taxa and their Names


Article 42. The genus group.

42.1. Definition. The genus group, which is next below the family group and next above the species group in the hierarchy of classification, encompasses all nominal taxa at the ranks of genus and subgenus (see also Articles 10.3 and 10.4).

42.2. Provisions applicable to all genus-group nominal taxa and their names. Genus-group nominal taxa and their names are subject to the same provisions whatever their rank, except when these apply explicitly at one rank alone.

42.3. Application of genus-group names. The application of each genus-group name is determined by reference to the type species [Arts. 61, 66 to 70] of the nominal taxon that it denotes.

42.4. Formation and treatment of genus-group names. A genus-group name is to be formed and treated in accordance with Articles 10.3, 10.4 and 11.8, and the relevant provisions of Articles 25 to 33.
