Using the principles and methods of phylogenetic systematics, the phylogenetic relationships among the basic closed descendent communities (monophyla) of the taxon Platyhelminthes are discussed.

A phylogenetic system of the Platyhelminthes is presented and several hypothesized autapomorphies of the well-known main subordinated monophyla of free-living and parasitic platyhelminths are named. A monophylum ‘Turbellaria’ does not exist in reality.
