Ataxon that does not include the last common ancestor of all its members is a group.

A monophyletic taxon is also called a clade. Paraphyletic taxon : A group composed of a collection of organisms, including the most recent common ancestor of all those organisms. Unlike a monophyletic group, a paraphyletic taxon does not include all the descendants of the most recent common ancestor.

Does this help?
