Principles of ICZN

• 1. (Principle of Binomial Nomenclature) Zoological nomenclature is independentof other systems of nomenclature, forexample botanical nomenclature. This implies that animals can have the same generic names as plants.
• In the system of nomenclature for animals the name of a species is composed of a combination of a genus name and a species name, together they make a binomial name.
• (Principle of Priority) The correct formal scientific name for an animal taxon, the name that is to be used is called the valid name, and is the oldest available name that applies
• (Principle of Coordination) The act of publishing a new zoological name automatically and simultaneously establishes all the corresponding names in the relevant other ranks, with the same type.
• (Principle of First Reviser) In cases of conflicts between simultaneously published divergent acts, the first subsequent author can decide which one shall be regarded as the one that should have precedence.
• (Principle of Homonymy) The name of each taxon must be unique
• (Principle of Typification) Any named taxon would have a name-bearing type which allows the objective

  application of that

  name.
