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
Convoluta sp. nov. (= Convoluta pulchra Smith JPS, Bush L 1991 (citation))
