the difference is surely one of how the backbone of the phylogeny would be reconstructed if the taxon in question were coded as a character and you say coded under deltran optimisation. but there will be a class of ambiguous cases which i think are usually called polyphyletic.

I've generally taught that when evaluating previously named taxa in the
light of phylogenetic analysis, paraphyletic groups are those that some
folks will defend to the death, while polyphyletic groups are those most
people realize are "mistakes"! - Barry
