Boguta KK 1970 (citation)- Definition, description in Russian- English summary. "Anaperus biaculeatus species new offters two large glandular aculer (prostomis composita) in the region of the male sexual aperture. Antrum is not differentiated. Penis is absent. The species possesses 25-30 bursal organs. Gonads are not twin; testis is dorsal, ovary is ventral. Anaperus biaculeatus has a broad and flat body which attains 5 mm in length. The ventral surface of the body is able to invaginate. the colour of Anaperus biaculeatus varies from yellow to organge due to the dermal glands containing a secretory substance of a peculiar form. The species was observed at a depth of 0-2 meters within the slime line of Tchupa Bay." Boguta KK 1972 (citation)- Early development of. Boguta KK 1972 (citation)- Early development of.

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:

[translated summary "...differentiation of the secretory cells of the epidermal glands in the parenchyma,
and the presence of muscular and nervous elements in the epidermal layer, leads to the conclusion that in
the Acoela there is a close interrelation between the parenchyma and the epidermis, and that phagocytoblast
and kinoblast are still poorly separated."]
