“…The interaction of these two uses of available names, as contended by John & Vane-Wright (2019), creates a further problem -that of confusion in communication. Thus in this case, if I use the name Danaus dorippus, am I referring to a taxon of the species group (species, superspecies, allospecies, semispecies, subspecies - Helbig et al 2002), or to a phenotype that can transcend the boundaries of geographically circumscribed taxa, and thus be regarded as a form found in two or more species group taxa due to gene flow, shared descent (trans-species polymorphism in the sense of Ségurel et al 2012), or convergent evolution?…”
