Protofrankia

Recommendation 10

Authors should attend to the following Recommendation and those of Recommendation 9 when forming genus names.

1. Names that have the same suffixes as those used for the higher taxonomic ranks should be avoided: -aceae, -ales, -ia, and -ota (see Table 1).

Rule 16

Each named taxon must have a designated nomenclatural type. The nomenclatural type, referred to in the SeqCode as “type”, for a species or subspecies is the evidence for that taxon (DNA sequence, see Rule 18a) with which the name is permanently associated. For taxa above the rank of species, the type is one of the subordinate taxa, with which the name is permanently associated. Formation of names of the taxa above the level of genus is based on the names of the types, allowing tracing which biological entity is included in the taxon. The nomenclatural type is not necessarily the most typical or representative element of the taxon.

Types of the various taxonomic categories are presented in Table 2.

Rule 17

The type of a taxon must be designated for the name to be validly published (see Section 5).

Rule 26

A name of a new taxon, or a new combination for an existing taxon, is not validly published unless the following criteria are met:

1. The name is effectively published under the rules of the SeqCode.
2. The name is registered in the SeqCode Registry, along with mandatory data fields listed below.
3. The type of the taxon is clearly designated. In the case of species or subspecies, the type sequence is deposited according to Rule 18a and the accession number cited.
4. The taxonomic rank is designated.
5. The derivation (etymology) of a new name (and if necessary of a new combination) is given wherein one or more distinguishable roots are identified. Roots can originate from any language in use or extinct (see also Recommendation 9).

Note 1. When a new species or a new combination results in the proposal of a new genus, both the new genus name and the new species name or the new combination must be validly published. Publication of the new species epithet or new combination alone does not constitute valid publication of the new genus name.

Note 2. When possible, authors are recommended to include the SeqCode Registry identifier in the effective publication.

Note 3. If the information provided in the registration and the effective publication differ, the registration is considered definitive.

Rule 21a

The nomenclatural type of a genus is the type species that was designated when the genus name was originally validly published.

Rule 24a

Effective publication under the SeqCode means that the name and evidence for the taxon have been published in a peer-reviewed journal or book.

Rule 26

A name of a new taxon, or a new combination for an existing taxon, is not validly published unless the following criteria are met:

1. The name is effectively published under the rules of the SeqCode.
2. The name is registered in the SeqCode Registry, along with mandatory data fields listed below.
3. The type of the taxon is clearly designated. In the case of species or subspecies, the type sequence is deposited according to Rule 18a and the accession number cited.
4. The taxonomic rank is designated.
5. The derivation (etymology) of a new name (and if necessary of a new combination) is given wherein one or more distinguishable roots are identified. Roots can originate from any language in use or extinct (see also Recommendation 9).

Note 1. When a new species or a new combination results in the proposal of a new genus, both the new genus name and the new species name or the new combination must be validly published. Publication of the new species epithet or new combination alone does not constitute valid publication of the new genus name.

Note 2. When possible, authors are recommended to include the SeqCode Registry identifier in the effective publication.

Note 3. If the information provided in the registration and the effective publication differ, the registration is considered definitive.
