Chapter 14: Types in the Family Group


Article 63. Name-bearing types. The name-bearing type of a nominal family-group taxon is a nominal genus called the "type genus"; the family-group name is based upon that of the type genus [Art. 29]. (See also Articles 11.7, 35, 39 and 40).

63.1. Coordinate nominal taxa. Coordinate nominal taxa of the family group have the same type genus [Arts. 36, 37, 61.2].

"Name-bearing types. The name-bearing type of a nominal family-group taxon is a nominal genus-group taxon called the "type genus"; the family-group name is based upon that of the type genus [Art. 29]. (See also Articles 11.7, 35, 39 and 40). ". The type genus can currently be classified at the generic or subgeneric rank.

Example.
The gastropod family name Agriolimacidae was based on the genus Agriolimax Mörch, 1865. Today Agriolimax is commonly regarded as a subgenus of Deroceras Rafinesque, 1820.

A discussion on the [iczn-list] mailing list in Feb 2011 revealed that the present wording created the possible misunderstanding that if a type genus is classified as a subgenus, the family may lose its identity.

Alternatively, the Glossary could define "nominal taxon" better, in accordance with its usage here and in Art. 67.1. See Glossary. It seems to me that "nominal species", "nominal species and subspecies" and "nominal species-group taxon" is the same. The Code should consistently use only one expression.
