LepsGlossary (P)
page precedence
When two names for the same taxon are first published in the same publication, then the one which appears on the earlier page has precedence. Page precedence does not necessarily mean priority as well — this is determined by the action of the first reviser. See also: Line precedence.
paralectotypeAny one of the original syntypes remaining after the selection of a lectotype.
paratypeEvery specimen in a type series other than the holotype which were before the author at the time of preparation of the original description and were so designated and indicated there.
part of the List of Available Names in ZoologyA list, adopted by the Commission under Article 79 (ICodeZN), of available names in a major taxonomic field.
perfect namesee Nomen perfectum.
phenetic classificationClassification based on degree of overall similarity.
phenotypeThe total characteristics of an individual (i.e. its appearance) resulting from interaction between its genotype and its environment.
Plenary PowersThe Commission is empowered by use of its Plenary Powers to prevent the application of a rule of the Code where such application in a particular case would disturb the stability or universality or cause confusion in zoological nomenclature. Articles 78, 81 (ICodeZN).
plesiotypeA specimen identified by a subsequent author as belonging to a particular species.
potentially valid nameAn available name which is not objectively invalid.
precedenceThe order of seniority of available names or nomenclatural acts determined
preoccupied name— by application of the Principle of Priority as specified in Article 23 (ICodeZN), or — in the case of simultaneously published names or acts, as specified in Article 24 (ICodeZN), or — by a ruling of the Commission using its Plenary Power. The later published of two identical but independently proposed names for the same or different taxa. = Junior homonym.
preprintA work published, with its own specified date of publication (imprint date), in advance of its later reissue as part of a collective or cumulative work. Preprints may be published works for the purposes of zoological nomenclature. See also: Separate.
prevailing usagesee Usage, prevailing.
primary homonymEach of two or more identical species names, which, at the time of original publication, were proposed in combination with the same generic name i.e. the species were named for different, though homonymous genera. See also: Homonym.
principle of binominal nomenclatureThe principle that the scientific name of a species, and not of a taxon at any other rank, is a combination of two names (a binomen); the use of a trinomen for the name of a subspecies and of uninominal names for taxa above the species group is in accord with the Principle. See Articles 5, 11.4 (ICodeZN).
principle of coordinationThe principle that within the family group, genus group or species group a name established for a taxon at any rank in the group is deemed to be simultaneously established with the same author and date for taxa based on the same name-bearing type at other ranks in the group [Articles 36, 43, 46 (ICodeZN)].
principle of homonymyThe principle that the name of each taxon must be unique. Consequently a name that is a junior homonym of another name must not be used as a valid name [Article 52 (ICodeZN)].
principle of priorityThe principle that the valid name of a taxon is the oldest available name applied to it (taking into consideration the other provisions of Article 23 (ICodeZN)), provided that the name is not invalidated by any provision of the Code or by any ruling by the Commission [Article 23 (ICodeZN)].
principle of the first reviserThe principle that the relative precedence of two or more names or nomenclatural acts published on the same date, or of different original spellings of the same name, is determined by the First Reviser [Article 24.2 (ICodeZN)].
principle of typificationThe principle that each nominal taxon in the family group, genus group or species group has, actually or potentially, a name-bearing type fixed to provide the objective standard of reference by which the application of the name is determined [Article 61 (ICodeZN)] (see Typification).
printer’s errorAn incorrect spelling made in type-setting (often called typographical error).
priority, of a name or nomenclatural actSeniority fixed by the date of availability.
priority, principle ofsee Principle of priority.
pro parte, p. p.In part, used in author citations to show that only part of a taxon, as defined by a previous author, is being referred to by the writer.
proposal to Commissionsee Application to commission.
protected namesee Nomen protectum.
provisionsTerm equivalent to rules.
publication(1) — Any published work; (2) — The issuing of a work conforming to Articles 8 and 9 (ICodeZN).
published nameAny name which is printed and circulated (i.e. meets the criteria of publication as stated by the ICodeZN Articles 8 & 9), may be available, unavailable, valid or invalid.
