Ax P, Doerjes J 1966 (citation)- description and illustration - is from fresh water- 1st fresh water acoel- collected in many places in Germany under stones in rivers, pilings, logs, etc. A rheopile organ. Klima 1967 (citation)- electron microscopy work on. Dorjes J 1968 (citation)- problems iwth genus and this species - 10-40 bursae, and p 89 lists. Kolasa J, Faubel A 1974 (citation)- mentions as only other fresh water species. Riser NW 1974 (citation)- p 519 mentions embryology of in his review. Henley C 1974 (citation)- p 277 - notes Ax P, Doerjes J 1966 (citation) found 10-40 bursae, also p 279- found 8 pairs each with nozzle of ventral prostaboid organ. Kolasa J 1977 (citation)- on marine origin of this. Smith JPS 1981 (citation)- mentions electron microscopy on by Klima 1967 (citation).
Smith JPS, Tyler S 1985 (citation)- "The acoel turbellarians: kingpins of metazoan evolution or a specialized
offshoot?" Look at ultrastructural characters (body wall, parenchyma, digestive tract). "....it appears
that acoels are derived, and cannot logically be fitted into any of the current theories of interphyletic
relationships, either as models of primitiveness or as reduced coelomates. Instead, the Nemertodermatida,
sister group to the Acoela, and the Catenulida appear more primitive, and consideration of these groups for
phylogenetic schemes is more likely to bear fruit." Species of Acoela include:
Diopisthoporus cf. longitubus
Diopisthoporus sp. (= Diopisthoporus gymnopharyngeus Smith JPS, Tyler S 1985 (citation))
Hesiolicium inops
Convoluta convoluta
