Clamps in various genera of Protomicrocotylidae. Black: additional sclerite, characteristic of the Mazocraeidea

Mazocraeidea is an order of flatworms in the subclass Polyopisthocotylea within the class Monogenea.

The species of this order have various structures in the clamps of their posterior attachment organ, including additional sclerites in the Gastrocotylidae and related families. However, these additional sclerites, and even the clamps themselves, are lacking in certain members of the family Protomicrocotylidae.
