EOL Text
The triclads (Tricladida) constitute an order of free-living platyhelminths characterized by a gut divided in three main branches or trunks and by the anterior position of the ovaries, next to the brain. As many other free-living platyhelminthes, the triclads are popularly known as planarians or flatworms.
Triclads inhabit marine environments (Maricola), freshwater bodies (Dendrocoelidae, Dugesiidae, Kenkiidae, Planariidae) and terrestrial habitats (Geoplanidae).

Noren & Jondelius (2002) (citation) declare "The Neoophora is rendered non-monophyletic by the sister-group position of the ‘archoophoran’ Haplopharynx rostratus Meixner, 1938 (Haplopharyngida) to the Lecithoepitheliata, with moderate support" on p. 408.
However, Rieger (2001) (citation) also considered such molecular-sequence data (from Littlewood et al. 1999) (citation) and rejected the notion that Haplopharynx rostratus would fall outside of the Macrostomorpha in light of the numerous morphological characters and their evolution within the Macrostromorpha. That is, a split of the Macrostomida and Haplopharyngida is not valid, and a sister-group relation between Haplopharyngida and Lecithoepitheliata is unlikely. The only morphological characters supporting the Haplopharyngida/Lecithoepitheliata relationship are those of the penial structures and the follicular surrounding of accessory cells.
