Paraphyly

Reptilia (green field) is a paraphyletic group comprising all amniotes (Amniota) except for two subgroups Mammalia (mammals) and Aves (birds); therefore, Reptilia is not a clade. In contrast, Amniota itself is a clade, which is a monophyletic group.

Wasps are paraphyletic, consisting of the clade Apocrita without ants and bees, which are not usually considered to be wasps.

In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups. The group is said to be paraphyletic with respect to the excluded subgroups. The term is commonly used in phylogenetics (a subfield of biology) and in linguistics.
