Nomenclature of parthenogenetic, gynogenetic and hybridogenetic vertebrate taxons: new proposals

Article published in volume 8 fascicle 3, of 10/1990, pages 61 - 74



In order to homogenize, standardize and simplify the nomenclature of parthenogenetic, gynogenetic and hybridogenetic vertebrate taxons, new proposals are made, which rely on a clear separation between the need of a single nomenclatural system at the species level for all living animals, and that of a distinction between different kinds of evolutionary units in nature. Three major kinds of species-rank taxons can be distinguished in animals: (1) species (s. str.), or bisexual species, with sexual reproduction (including normal meiosis, usually with recombination, fertilization of egg by sperm, and non-clonal inheritance); (2) kleptons, which depend on sexual parasitism for their reproduction, and which include zygokleptons (with sexual reproduction, hybridogenetic meiosis, fertilization of egg by sperm, and hemiclonal inheritance) and gynokleptons (with parasexual reproduction, modified meiosis or ameiosis, gynogenesis, and clonal inheritance); (3) klonons, with parasexual or asexual reproduction, modified meiosis or ameiosis or absence of gametes, parthenogenesis or absence of germ, and clonal inheritance. All these evolutionary systematics categories are considered here to be of the same nomenclatural rank within the Linnaean system, that of species, and names of the corresponding taxons should be submitted to the same rules, those of the International Code for Zoological Nomenclature for species names. To distinguish kleptons and klonons from species (s. st.), it is suggested to add the abbreviations kl. and kn., respectively, between the generic and the specific names.
