This page is about the general term. For the phylotypic stage of vertebrates, see Pharyngula

A phylotype is an observed similarity that classifies a group of organisms by their phenetic relationship. This phenetic similarity, particularly in the case of asexual organisms, may reflect the evolutionary relationships. The term is rank-neutral,[1] thus one can choose the rank at which the phylotype is described, e.g. species, class, 97% genetic similarity or homology. The term is often used in microbiology since the genomes of prokaryotes do not lend themselves to classification via Linnean taxonomy as easily as do many eukaryotes such as plant and animals.

A related meaning of phylotype is the phylotypic stage, a point in embryogenesis where "all members in the taxon look essentially the same".[2]
