If it is fair to change criteria, then I would say that a phylogenetic
species cannot exclusively be phenetic.  Examples would include units with
a common phylogenetic past which is also a contributing source of other
functional demarcations such as phenetic similarity, reproductive
isolation, recognition, cohesion, and evolutioary fate.

Throw in homoploid reticulate evolution and the whole thing falls apart.
