Trematoda - Flukes, probably paraphyletic to Cestoda.
Cestoda - Tapeworms
Monogenea - Ectoparasitic flukes with simpler life cycles than Trematode flukes. They live an exclusively parasitic existence.

The flatworms (Platyhelminthes, Greek "platy"': flat; "helminth": worm) are a phylum of relatively simple soft-bodied invertebrate animals. With about 25,000 known species they are the largest phylum of acoelomates.
