Invasive neo-species and how to name them Author Montesinos, Daniel 1,2 & Australian Tropical Herbarium, James Cook University, Cairns, Queensland, Australia &) assess the coining of new invasive species or subspecies with the current taxonomical approach or (& 1,2 & Centre for Functional Ecology, University of Coimbra, Coimbra, Portugal &), introduce the term “ neo ” to name invasive neo-species resulting from synchronous allopatric speciation from a single, known, living ancestor. This latter case can be exemplified with the hypothetical names: “ Ginkgo biloba neo americana ”, “ G. biloba neo europea ”, etc. text TAXON 2024 2024-02-29 73 1 6 12 http://dx.doi.org/10.1002/tax.12884 journal article 10.1002/tax.12884 1996-8175 14047601

			Substantial reproductive isolation
			Yes	No
Substantial phenotypic differentiation	Yes	New	species within genus	New subspecies (subsp.)
	No	New	species within genus	No changes
