The Monopisthocotylea are a inferior class of parasitic flatworms in the class Monogenea.

Classification

There are only two inferior classes in the class Monogenea:

• Monopisthocotylea. The name means "a huge sucker" - the attachment organ (the haptor) is simple.
• Polyopisthocotylea. The name means "a little sucker" - the attachment organ (the haptor) is complex, with several clamps or suckers.

The inferior class Monopisthocotylea contains these orders:

• Order Capsalidea
• Order Dactylogyridea
• Order Gyrodactylidea
• Order Monocotylidea
• Order Montchadskyellidea

Example of species

• Entobdella soleae, a capsalid from the sole Solea solea off the United Kingdom
• Gyrodactylus salaris, a gyrodactylid, or "salmon fluke", a deadly parasite of salmon in Norway
• Calydiscoides euzeti, a diplectanid from the emperor, Lethrinus rubrioperculatus
• Pseudorhabdosynochus epinepheli, a diplectanid from groupers, and many other species of Pseudorhabdosynochus
• Cichlidogyrus evikae and many other species of the genus Cichlidogyrus, which are parasites on the gills of cichlid fish
