Digenea

Adult schistosomes share all the fundamental features of the digenea.

It is a subclass of the trematoda, and sister group to the Digenea.

They belong to the Digenea, a large subclass of flukes.

Protandry is the general rule among the Digenea.

They have direct life-cycles with no asexual reproduction (unlike the Digenea).

The Echinostomida are an order of flatworms, belonging to the large group Digenea.

Trematodes are divided into two groups, Digenea and Aspidogastrea (also known as Aspodibothrea).

The Digenea, which constitute the majority of trematode diversity, are obligate parasites of both mollusks and vertebrates, but rarely occur in cartilaginous fish.

In 1953, kainic acid was originally isolated from the seaweed called "Kainin-sou"(海人草) or "Makuri" (Digenea simplex) in Japan.

A similar tegument is found in other members of the Neodermata; a group of platyhelminths comprising the Digenea, Aspidogastrea, Monogenea and Cestoda.

Evidence for this comes from the ubiquity of molluscs as first intermediate hosts for digeneans, and the fact that most aspidogastreans (the sister group to the Digenea) also have mollusc associations.

Levinseniella deblocki, new species (Trematoda: Digenea: Microphallidae) from salt marshes along the eastern Gulf of Mexico with notes on its functional morphology and life history (abstract only).

Characteristic features of the digenea include a syncitial tegument; that is, a tegument where the junctions between cells are broken down and a single continuous cytoplasm surrounds the entire animal.

The evolutionary origins of the Digenea have been debated for some time, but there appears general agreement that the proto-digenean was a parasite of a mollusc, possibly of the mantle cavity.

The lizard harbors parasites such the digenea flatworm Mesocoelium monas and several nematodes, such as Oswaldocruzia vitti, Physalopteroides venancioi, Strongyluris oscari, and Physaloptera retusa.
