Article 79. List of Available Names in Zoology. An international body of zoologists (such as an International Congress, an international society, or a consortium of national or regional societies, or a Scientific Member of the International Union of Biological Sciences) in consultation with the Commission may propose that the Commission adopt for a major taxonomic field (or related fields) a Part of the List of Available Names in Zoology. The Commission will consider the proposal and may adopt the Part subject to the proposing body and the Commission meeting the requirements of this Article.

79.1. Form of the proposal. The proposal to the Commission shall be made in the form of the Part proposed for adoption and shall

79.1.1. specify the scope of the proposal, such as the taxonomic field, ranks, and time period covered, (e.g. Amphibia, Names of the Species Group established before 31 December 1995 [full date, i.e. day, month, year]);

79.1.2. for each name to be listed, give the bibliographic reference to the work in which it is established, its authorship, its date of publication and its status (including its precedence if this is different from its priority);

79.1.3. for each name to be listed, give details of the name-bearing type of the nominal taxon it denotes; in the case of a species-group name, if the details of how the type specimen(s) may be recognized are not known, state whether the name is based on a holotype, syntypes, lectotype or neotype and the place(s) of deposition (if any) recorded in the type fixation (but no lectotype or neotype designation can be made for the purposes of listing alone [Arts. 74.7, 75.3]);

79.1.4. for any name to be listed which has been the subject of a Commission ruling [Arts. 80, 81], give the relevant Opinion and the status of the name as ruled therein; and

79.1.5. if applicable, specify how homonymy with names beyond the scope of the proposal has been resolved.

79.2. Requirements concerning notification, consultation and voting by the Commission.

79.2.1. Upon being advised by an international body of zoologists that it intends to propose a Part of the List, the Commission shall appoint by its Council an ad hoc committee [Constitution Art. 10] to consult with the proposers.

79.2.2. Upon receipt of a proposal the Commission shall

79.2.2.1. publish a notice of the proposal in the Bulletin of Zoological Nomenclature giving details of the proposing body, proposed scope of the Part and a source from which copies (on paper or otherwise) of the proposed Part may be obtained by zoologists, and inviting comments from zoologists during the following twelve months;

79.2.2.2. submit the notice for publication in journals publishing taxonomic work in the taxonomic field covered by the proposal;

79.2.2.3. refer the proposal to its ad hoc committee for it to receive comments, consult with the proposers and others and, not less than two years from the date of publication of the notice referred to in Article 79.2.2.1, consider either a revised proposal or a recommendation that the proposal be abandoned;

79.2.2.4. ensure that the revised proposal does not contain any name established less than five years before the submission of the initial proposal;

79.2.2.5. following receipt of the revised proposal from its ad hoc committee, publish notice of it and invite comments on the revised proposal in the same manner as for the initial proposal [Arts. 79.2.2.1, 79.2.2.2];

79.2.2.6. take into account comments received (if any) and comments of the proposers thereon, and vote to adopt the Part proposed or to abandon the proposal, under procedures prescribed in the Constitution [Art. 12] and the Bylaws of the Commission for voting under its plenary power.

79.3. Effective date of Parts and their accessibility. The Commission shall publish a notice in the Bulletin of Zoological Nomenclature of a decision to adopt any Part of the List of Available Names in Zoology as soon as possible after the decision is taken.

79.3.1. Before publishing the notice of adoption, the Commission shall satisfy itself that the Part newly adopted is accessible either by purchase or gratis and shall include that information in the notice.

79.3.2. Any Part of the List of Available Names in Zoology adopted by the Commission becomes effective from the date of publication in the Bulletin of Zoological Nomenclature of a notice of the decision of the Commission to adopt it.

79.3.3. The notice shall specify the title under which the Part of the List adopted by the Commission shall be known and its scope (including the taxonomic field and dates covered).

79.4. Status of names, spellings, dates of availability, and types specified in the List of Available Names in Zoology.

79.4.1. A name occurring in an adopted Part of the List of Available Names in Zoology is deemed be an available name and to have the spelling, date, and authorship recorded in the List (despite any evidence to the contrary).

79.4.2. A nominal taxon denoted by a name occurring in an adopted Part of the List of Available Names in Zoology is deemed to have the name-bearing type recorded therein (despite any evidence to the contrary).

79.4.3. No unlisted name within the scope (taxonomic field, ranks, and time period covered) of an adopted Part of the List of Available Names in Zoology has any status in zoological nomenclature despite any previous availability.

Recommendation 79A. Citation of previously available names. If for taxonomic and historical purposes an author desires to cite a name that is no longer available because it is not included in the relevant Part of the List of Available Names in Zoology adopted by the Commission, it should be made clear that it no longer has a status in zoological nomenclature.

79.5. Power of the Commission to amend the status of a name occurring in the List of Available Names in Zoology. If there are exceptional circumstances and only when an entry in the List of Available Names in Zoology is a cause of confusion, the Commission may amend the entry by use of its plenary power [Art. 81] and publish its ruling in an Opinion [Art. 80.2].

79.5.1. From the date of the publication in the Bulletin of Zoological Nomenclature of the amended entry the relevant name has the status, spelling, date of availability, and authorship, and the nominal taxon it denotes has the name-bearing type, as shown in the amended entry.

79.5.2. The requirement that amendments to the status of names occurring in the List may be made only by the Commission using its plenary power does not prevent an author from designating a type species for a nominal genus-group taxon published before 1931, if one has not already been fixed, or from designating a lectotype [Art. 74] from syntypes recorded in the List of Available Names in Zoology, or a neotype when circumstances exist that require neotype designation [Art. 75]. Such subsequent fixations may be inserted by the Commission in the List.

Recommendation 79B. Request to authors designating lectotypes or neotypes for names in the List of Available Names in Zoology. Authors are requested to inform the Commission of lectotype or neotype designations made by them for the nominal taxa of names in the List of Available Names in Zoology as soon as possible after publication.

79.6. Power of the Commission to add omitted names to the List of Available Names in Zoology. If the Commission determines that there is a previously available name within the scope of an adopted Part of the List of Available Names in Zoology that has been omitted from the List, in exceptional circumstances the Commission may by use of the plenary power add an appropriate entry to that Part of the List and record this in an Opinion. The availability of the name thereby becomes restored.
