[1][2] The International Society for Phylogenetic Nomenclature (ISPN) was established in the first international phylogenetic nomenclature meeting, which convened in the Muséum national d'histoire naturelle, in Paris, on July 6–9, 2004.
It was also decided then to expand the CPN (Committee on Phylogenetic Nomenclature) from nine to twelve members.
The editors of the Companion Volume presented a progress report, and a demonstration of the RegNum on-line registration database was given.
Shortly after that meeting, the ISPN was admitted as a scientific member of IUBS, the International Union of Biological Sciences, to which other regulating bodies of biological nomenclature (such as the International Association for Plant Taxonomy and the International Commission on Zoological Nomenclature, among others) also belong.
