Azygiida is an order of flatworms belonging to the class Rhabditophora. [1]

Digenea is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms with a syncytial tegument and, usually, two suckers, one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6,000 species have been described to date.
Plagiorchiida is a large order of trematodes, synonymous to Echinostomida. They belong to the Digenea, a large subclass of flukes. This order contains relatively few significant parasites of humans.
Echinostomata is a suborder of the parasitic flatworm order Plagiorchiida. The suborder contains numerous species that are parasitic in humans.
Psilostomatidae is a family of trematodes in the order Plagiorchiida. They parasitise aquatic vertebrates as definitive hosts.
Opisthorchiidae is a family of digenean trematodes. Opisthorchiidae have cosmopolitan distribution.
