How to … Write a protologue for a new species (or infraspecific) name
A protologue is everything associated with a name at its valid publication, e.g. a description, diagnosis, illustrations, references, synonymy, geographical data, citation of specimens, discussion, comments, etc.
A protologue may be a whole paper (where the paper deals with only one taxon) or a part of a (multi-taxon) paper. In modern practice, a protologue is usually a taxonomic entry in a taxonomy section of a paper.
A protologue of a species or infraspecific name must have the following elements:
The new name itself, which should be followed by a designation of its nomenclatural status, e,g, sp. nov., subsp. nov., comb. nov., stat. nov., or nom. nov. (see How to indicate the nomenclatural status of a new name).
For the name of a new taxon, the word “holotypus” or “typus”, or its abbreviation (e.g. "holo."), or its equivalent in a modern language (e.g. "holotipo", "holotype", "tipo", "type"), followed by
an unambiguous designation of the holotype specimen (see How to choose a type specimen for a name of a new species and How to cite a specimen), followed by
specification of the single herbarium or collection or institution in which the holotype specimen is conserved (see How to cite a herbarium), and
if the type is a culture, a statement that it is preserved in a metabolically inactive state.
For the name of a new taxon, a description and/or a diagnosis; note that at least one of these must be in either English or Latin.
- For a new combination, name at new rank, or replacement name, a full and direct reference to the basionym or replaced synonym, including author and place and year of publication (see How to fully and directly cite a name).
- For a fungal name (including fossil fungi), the identifier issued for the name by a recognized repository must be cited in the protologue (Art. F.5).
