holophylyHolophylie (ger.)

  [A monophyletic group comprises all descendants of a group of individuals that at their time belonged to a [...] single biological species"

  I propose the word holophyly, a tribe of all, for the concept that Hennig calls monophyly. Holophyly and paraphyly, then, become two aspects of the more general concept, monophyly.
