Is the Turbellaria polyphyletic
Hydrobiologia, 1986Within the last two decades, syntheses of both light-microscopic and ultrastructural characters have shown that there are three well-defined monophyletic groups within the Platyhelminthes: 1) the Catenulidale, 2) the Nemertodermatida-Acoela, and 3) the Haplopharyngida-Macrostomida-Polycladida-Neoophora (+ parasitic platyhelminth classes).

Philosophical Transactions of the Royal Society of London, 1879
Two forms of considerable interest belonging to this group were found to be tolerably abundant. They belong to the genera Tetrastemma and Geoplana , I can scarcely entertain a doubt that these animals will finally prove to have a much wider geographical range, or, in other words, that it ...

Entre los Platyhelminthes, los turbelarios son tradicionalmente reconocidos como la clase que agrupa a los representantes de vida libre del phylum. Sin embargo, no tienen sinapomorfías que los definan, siendo la presencia de una epidermis ciliada en el adulto la característica principal que los relaciona, carácter ausente en las formas parásitas del ...

Parazitologiia, 2001
The ultrastructure of the epithelium in Notentera ivanovi (Turbellaria, Fecampiida) has been studied. Notentera ivanovi lacks the digestive system but has a pad of the epidermal cells on the dorsal side of the body, which seems to be similar to the digestive epidermis on LM.

Chemoreception in Turbellaria.
Experimental biology, 1989This paper reviews the ultrastructural features and the behavioural aspects of presumptive chemoreceptors as reported in the literature, and adds some new observations. The involvement of both uniciliary and multiciliary sensory receptors has been cited.

Freshwater Triclads (Platyhelminthes, Turbellaria) and Continental Drift
Nature, 1969THERE is no fossil record of the freshwater Tricladida but they are particularly suitable organisms for zoogeographical studies because of their low vagility. Their dispersal powers have been reviewed by several workers1–3 and the general absence of resistant eggs or stages, and the fragility of adults have led to the conclusion that the usual agencies

Revision of Koinocystididae (Turbellaria)
Zoologica Scripta, 1980The revision deals with the anatomy and systematics of the known 38 species of Koinocystididae. The taxonomy within the family is revised, a key for the identification of live specimens is given and an attempt is made to reconstruct the phylogeny of genera and species on the basis of anatomical transformation series. New genera are Axiutelga. Brunetia,
