Pseudophyllidea

thumb|Pseudophyllid Pseudophyllid cestodes (former order pseudophyllidea) are tapeworms with multiple "segments" (proglottids) and two bothria or "sucking grooves" as adults. Proglottids are identifiably pseudophyllid as the genital pore and uterine pore are located on the mid-ventral surface, and the ovary is bilobed ("dumbbell-shaped").

The order has been discovered by phylogenetic analysis to be paraphyletic, and has been broken up into two orders, Bothriocephalidea and Diphyllobothriidea. Eggs have one flat end (the operculum) and a small knob on the other end. All pseudophyllid cestodes have a procercoid stage in their life cycle, and most also have a plerocercoid stage.
