Acotylea is a suborder of free-living marine turbellarian flatworms in the order Polycladida.
Description
As currently defined, Acotylea includes polyclads with a Lang's vesicle in the female reproductive system and the male copulatory apparatus directed backwards. When tentacles are present, they are nuchal. The eyespot groups can be nuchal, cerebral, and marginal.
