This paper presents a revised classification for the higher taxa within the Tricladida. A historical sketch is provided of the higher classificatory systems of triclad flatworms. As far as possible, the new classification is based on published phylogenetic studies. A phylogenetic tree generalizing currently available hypotheses on the higher-taxon relationships of the Tricladida forms the backbone of the new classification. There is no longer any room in formal classifications for the taxon… 
Molecular phylogeny of Geoplaninae (Platyhelminthes) challenges current classification: proposal of taxonomic actions
TLDR
A phylogenetic hypothesis for selected taxa of Geoplaninae based on the molecular data is presented and discussed in the light of morphological features, and a number of well‐supported clades are unveiling morphologically homogeneous groups.
Planarian (Platyhelminthes, Tricladida) Diversity and Molecular Markers: A New View of an Old Group
TLDR
Case examples ranging from delimiting species in an integrative style, and barcoding them, to analysing their evolutionary history on a lower scale to infer processes affecting biodiversity origin, or on a higher scale to understand the genus level or even higher relationships are presented.
Phylogeny and biogeography of the Cavernicola (Platyhelminthes: Tricladida): Relicts of an epigean group sheltering in caves?
TLDR
The results point to an evolutionary scenario in which the Cavernicola originated in a freshwater habitat, subsequently radiated and colonized both epigean and hypogean environments, and the sister-group relationship to the Maricola falsify the morphology-based phylogeny of the latter.
Amphibioplanidae: a new branch and family on the phylogenetic tree of the triclad flatworms (Platyhelminthes: Tricladida), represented by a species from Sardinian caves with a remarkable lifestyle
TLDR
Molecular analysis reveals a sister-group relationship between this new family of cave-dwelling triclad flatworms, Amphibioplanidae, and the family Dimarcusidae of the suborder Cavernicola, together constituting the sister- group of thesuborder Maricola.
A molecular analysis of the phylogenetic position of the suborder Cavernicola within the Tricladida (Platyhelminthes), with the description of a new species of stygobiont flatworm from Benin
TLDR
This work is the first molecular study to demonstrate unequivocally that the Cavernicola does not group with either the freshwater planarians or the land planarians, i.e. is not closely related to the suborder Continenticola, and corroborates the suggested sister-group relationship with the marine triclads or Maricola.
Two new Geoplaninae species (Platyhelminthes: Continenticola) from Southern Brazil based on an integrative taxonomic approach
TLDR
Two new species of Geoplaninae are described, occurring in areas of ombrophilous forest which belong to the southern portion of the Brazilian Atlantic Rain Forest, and are sympatric in their type-locality.
An integrative taxonomic approach reveals the first marine triclad (Platyhelminthes) trapped in a cave from a semiarid Neotropical environment
TLDR
A new genus and species of the suborder Maricola, representing the first marine triclad living in freshwater within a cave, is described, and is characterised by a secondary copulatory bursa and ovaries located behind the root of the pharynx.
Towards a comprehensive, integrative analysis of the diversity of European microplaninid land flatworms (Platyhelminthes, Tricladida, Microplaninae), with the description of two peculiar new species
TLDR
This part of the study resulted in a re-evaluation of the taxonomic status of several nominal species and in the following taxonomic conclusions; the current diagnosis of the genus Microplana should be amended such that it refers to the situation that the species generally have two small eyes but occasionally may have multiple eyes.
Tracking the diversity of the flatworm genus Imbira (Platyhelminthes) in the Atlantic Forest
TLDR
The Bayesian and maximum likelihood analyses based on DNA barcoding recovered the monophyly of the genus Imbira, but indicate that specimens representing I. marcusi correspond to five distinct lineages, and sequence analysis revealed 32 molecular autapomorphies for all independent evolutionary units within the genus.
The evolutionary terrestrialization of planarian flatworms (Platyhelminthes, Tricladida, Geoplanidae): a review and research programme
  • R. Sluys
  • Biology
    Zoosystematics and Evolution
  • 2019
TLDR
A framework of a research programme is sketched, which has as its main objective to test hypotheses on the evolution of land planarians, specifically whether particular anatomical and physiological key innovations have contributed to their evolutionary successful terrestrial colonization and radiation.

We explore and review the taxonomic distribution of morphological features that may be used as supporting apomorphies for the monophyletic status of various taxa in future, more comprehensive
A robust molecular phylogeny of the Tricladida (Platyhelminthes: Seriata) with a discussion on morphological synapomorphies
TLDR
The results show that the Maricola is monophyletic and is the primitive sister group to the rest of the Tricladida (the Paludicola plus the Terricola), which is suggested to be a new clade, the Continenticola, which comprises the families Dugesiidae, Planariidae, Dendrocoelidae and the terricola.
Phylogenetic relationships of the triclads (Platyhelminthes, Seriata, Tricladida)
TLDR
A phylogenetic hypothesis for the triclads is presented and the characters on which it is based are discussed, with the result that it is postulated that the Maricola is the primitive sister group of the Terricola and the Paludicola together and that thePaludicola represents the most advanced group within the Tricladida.
Global diversity of free living flatworms (Platyhelminthes, “Turbellaria”) in freshwater
TLDR
Diversity of turbellarian species by biogeographical regions is reviewed, suggesting that species richness may be at least one order of magnitude higher than the currently reported number of species.
Molecular phylogeny of the Platyhelminthes
TLDR
Phylum-wide analyses based on complete ribosomal and other nuclear genes addressed to answer the main issues facing systematics and phylogeny of Platyhelminthes are reviewed.
Molecular phylogeny of land and freshwater planarians (Tricladida, Platyhelminthes): from freshwater to land and back.
TLDR
New molecular data including sequences of nuclear genes, 28S rDNA, and a mitochondrial gene (COI) of a wider sample of dugesiid and terricolan species support a monophyletic origin for Terricola followed by a likely return of some species to freshwater habitats.
Index of the genera and species of the freshwater triclads (Turbellaria) of the world
TLDR
An index is presented of the genera, subgenera, species, and subspecies of the freshwater triclads (Tricladida Paludicola or Probursalia) of the world, as well as their distributional areas and their principal morphological, taxonomic, and ecological literature.

TLDR
The Dimarcusidae represents a fourth lineage within the Tricladida and is more closely related to the Paludicola and Terricola than to the Maricola.

The phyletic status of the Paludicola
TLDR
There seems little doubt on morphological grounds of the close relationship between the Planariidae and the Dendrocoelidae but it is difficult to connect, phylogenetically, the Dugesiidae with these groups.
